Cowman, Brendan S. Crabb During blood stage Plasmodium falciparum infection, merozoites invade uninfected erythrocytes via a complex, multistep process involving a series of distinct receptor-ligand binding events. Understanding each element in this process increases the potential to block the parasite’s life cycle via drugs or vaccines. To investigate specific receptor-ligand interactions, they…

    I was invited by my friend Dax Rushlow to go Bigfoot hunting on snowmobiles in New Hampshire. I hadn’t had an adventure for awhile so I took him up on his offer. Let me tell you, when Dax says he knows where the Bigfoot are, you best believe him! I arrived at the airport late on Thursday and Dax was there to pick me up. We went back to his house where he had a nice bottle of wine waiting for me and his wife had bought some pizza for us. We chatted for awhile then crashed for the evening. We got up and out the next morning for our 4 hour drive up to the White Mountains. Driving up…

  • Preventing 1 case of HIV could save $338,400

    Karen Walters-Cornell
    27 Feb 2015 | 12:13 pm
    Preventing just one person at high risk from contracting HIV could save from $229,800 to $338,400, depending on the continuity of treatment. Researchers projected the savings by estimating the lifetime medical costs of people both with and without HIV, assuming that the HIV-infection occurred at age 35. The findings will be used by fiscal planners and public health advocates as they evaluate current prevention programs and make decisions about resource allocation. One relatively new—and expensive—HIV prevention option is pre-exposure prophylaxis (PrEP), which is targeted at high-risk…
  • Bluebird moms can make competitive sons

    Daniel Stolte-Arizona
    27 Feb 2015 | 11:54 am
    Female bluebirds can produce more or less competitive sons by influencing the amounts of hormones in their eggs, say biologists. “Mothers are uniquely positioned to be a bridge between current environmental conditions and the traits of their offspring,” says Renée Duckworth, an assistant professor in the department of ecology and evolutionary biology in the University of Arizona College of Science. “This is one of those rare cases where we can see how these local behavioral interactions, which can be exceptionally variable, can lead to highly predictable ecological patterns…
  • How tiny wires trap a ‘tornado’

    Phil Sneiderman-JHU
    27 Feb 2015 | 11:40 am
    Wires only a billionth as thick as a human hair may help keep the “super” in superconductivity. Superconductors are materials that, at low temperatures, can carry electric current without the wasteful loss of energy caused by resistance. But this useful ability can be crippled or lost when electrons swirl into tiny tornado-like formations called vortices. Magnetic fields, such as those produced by electric motors, can cause these disruptive mini-twisters. Physicists have now figured out how to trap troublesome vortices within extremely short, ultra-thin nanowires, keeping…
  • Can alternating feast and famine boost health?

    Morgan Sherburne-Florida
    27 Feb 2015 | 9:43 am
    A recent clinical trial shows that a feast-or-famine diet may mimic some of the benefits of fasting. The findings also suggest that adding antioxidant supplements may counteract those benefits. Fasting has been shown in mice to extend lifespan and to improve age-related diseases. But fasting every day, which could entail skipping meals or simply reducing overall caloric intake, can be hard to maintain. “People don’t want to just under-eat for their whole lives,” says Martin Wegman, an MD-PhD student at the University of Florida College of Medicine and coauthor of the paper…

    Of the 29.1 million Americans living with diabetes, an estimated 8.1 million are undiagnosed. New research suggests a trip to the dentist could be an effective way to identify people who might diabetes and don’t know it. Published in the American Journal of Public Health, the study of 408 dental patients shows that using gingival crevicular blood (GCB) for hemoglobin A1c (HbA1c) testing produces values that are nearly identical to those obtained using finger stick blood (FSB), with a 99 percent correlation between the two samples.

  • Storks Could Be Poisoned By Pesticides During Migration To Africa

    News Staff
    28 Feb 2015 | 6:10 pm
    Not all storks migrate to Africa, many spend the winter in the Iberian Peninsula, where landfills have become a permanent source of food. Scientists from Extremadura have analyzed the presence of pollutants and pesticides (some prohibited in Spain) in the blood of nestlings from three colonies, two of which are close to landfill sites, and the results reveal that the main source of contamination can be due to the use of insecticides still used in African countries where the birds migrate to, who transfer their contaminated load onto their offspring through their eggs. read more

  • How to calculate wind chill

    Wind-chill, windchill, wind chill factor, wind chill index is an estimate of how cold you will feel at a given air temperature when there is a wind blowing. It is a popular tool used by weather presenters to make you feel worse about going outside when it’s cold and windy! Seriously, if, for example, the reported air temperature (as measured by a thermometer housed in one of those white boxes with the grills, a Stevenson screen, or shelter) is -7 Celsius and the wind is blowing at a steady 8 km/h, then it will “feel” like it’s -11 Celsius.

    by Richa Sardana, Xin Liu, Sander Granneman, Jieyi Zhu, Michael Gill, Ophelia Papoulas, Edward M. Marcotte, David Tollervey, Carl C. Correll, Arlen W. Johnson In eukaryotes, the highly conserved U3 small nucleolar RNA (snoRNA) base-pairs to multiple sites in the pre-ribosomal RNA (pre-rRNA) to promote early cleavage and folding events. Binding of the U3 box A region to the pre-rRNA is mutually exclusive with folding of the central pseudoknot (CPK), a universally conserved rRNA structure of the small ribosomal subunit essential for protein synthesis. Here, we report that the DEAH-box helicase…
  • PROTEIN TARGETING TO STARCH Is Required for Localising GRANULE-BOUND STARCH SYNTHASE to Starch Granules and for Normal Amylose Synthesis in Arabidopsis

    David Seung et al.
    24 Feb 2015 | 2:00 pm
    by David Seung, Sebastian Soyk, Mario Coiro, Benjamin A. Maier, Simona Eicke, Samuel C. Zeeman The domestication of starch crops underpinned the development of human civilisation, yet we still do not fully understand how plants make starch. Starch is composed of glucose polymers that are branched (amylopectin) or linear (amylose). The amount of amylose strongly influences the physico-chemical behaviour of starchy foods during cooking and of starch mixtures in non-food manufacturing processes. The GRANULE-BOUND STARCH SYNTHASE (GBSS) is the glucosyltransferase specifically responsible for…

  • A Human Platelet Calcium Calculator Trained by Pairwise Agonist Scanning

    Mei Yan Lee et al.
    27 Feb 2015 | 2:00 pm
    by Mei Yan Lee, Scott L. Diamond Since platelet intracellular calcium mobilization [Ca(t)]i controls granule release, cyclooxygenase-1 and integrin activation, and phosphatidylserine exposure, blood clotting simulations require prediction of platelet [Ca(t)]i in response to combinatorial agonists. Pairwise Agonist Scanning (PAS) deployed all single and pairwise combinations of six agonists (ADP, convulxin, thrombin, U46619, iloprost and GSNO used at 0.1, 1, and 10xEC50; 154 conditions including a null condition) to stimulate platelet P2Y1/P2Y12 GPVI, PAR1/PAR4, TP, IP receptors, and guanylate…

    by David G. García Münzer, Margaritis Kostoglou, Michael C. Georgiadis, Efstratios N. Pistikopoulos, Athanasios Mantalaris Mammalian cell cultures are intrinsically heterogeneous at different scales (molecular to bioreactor). The cell cycle is at the centre of capturing heterogeneity since it plays a critical role in the growth, death, and productivity of mammalian cell cultures. Current cell cycle models use biological variables (mass/volume/age) that are non-mechanistic, and difficult to experimentally determine, to describe cell cycle transition and capture culture heterogeneity.

    27 Feb 2015 | 2:00 pm
    by J. Harry Caufield, Marco Abreu, Christopher Wimble, Peter Uetz Large-scale analyses of protein complexes have recently become available for Escherichia coli and Mycoplasma pneumoniae, yielding 443 and 116 heteromultimeric soluble protein complexes, respectively. We have coupled the results of these mass spectrometry-characterized protein complexes with the 285 “gold standard” protein complexes identified by EcoCyc. A comparison with databases of gene orthology, conservation, and essentiality identified proteins conserved or lost in complexes of other species. For instance, of 285…

    by Tiberiu Teşileanu, Lucy J. Colwell, Stanislas Leibler Statistical coupling analysis (SCA) is a method for analyzing multiple sequence alignments that was used to identify groups of coevolving residues termed “sectors”. The method applies spectral analysis to a matrix obtained by combining correlation information with sequence conservation. It has been asserted that the protein sectors identified by SCA are functionally significant, with different sectors controlling different biochemical properties of the protein. Here we reconsider the available experimental data and note that it…

    by Young-Jun Kim, Oghomwen Igiesuorobo, Cathy I. Ramos, Hong Bao, Bing Zhang, Mihaela Serpe Stabilization of neurotransmitter receptors at postsynaptic specializations is a key step in the assembly of functional synapses. Drosophila Neto (Neuropillin and Tolloid-like protein) is an essential auxiliary subunit of ionotropic glutamate receptor (iGluR) complexes required for the iGluRs clustering at the neuromuscular junction (NMJ). Here we show that optimal levels of Neto are crucial for stabilization of iGluRs at synaptic sites and proper NMJ development. Genetic manipulations of Neto levels…

    by Junghyun Lim, M. Lenard Lachenmayer, Shuai Wu, Wenchao Liu, Mondira Kundu, Rong Wang, Masaaki Komatsu, Young J. Oh, Yanxiang Zhao, Zhenyu Yue Disruption of proteostasis, or protein homeostasis, is often associated with aberrant accumulation of misfolded proteins or protein aggregates. Autophagy offers protection to cells by removing toxic protein aggregates and injured organelles in response to proteotoxic stress. However, the exact mechanism whereby autophagy recognizes and degrades misfolded or aggregated proteins has yet to be elucidated. Mounting evidence demonstrates the selectivity…

    by Huy Q. Nguyen, Jonathan Nye, Daniel W. Buster, Joseph E. Klebba, Gregory C. Rogers, Giovanni Bosco The spatial organization of chromosomes within interphase nuclei is important for gene expression and epigenetic inheritance. Although the extent of physical interaction between chromosomes and their degree of compaction varies during development and between different cell-types, it is unclear how regulation of chromosome interactions and compaction relate to spatial organization of genomes. Drosophila is an excellent model system for studying chromosomal interactions including homolog…
  • Region-Specific Activation of oskar mRNA Translation by Inhibition of Bruno-Mediated Repression

    Goheun Kim et al.
    27 Feb 2015 | 2:00 pm
    by Goheun Kim, Chin-I Pai, Keiji Sato, Maria D. Person, Akira Nakamura, Paul M. Macdonald A complex program of translational repression, mRNA localization, and translational activation ensures that Oskar (Osk) protein accumulates only at the posterior pole of the Drosophila oocyte. Inappropriate expression of Osk disrupts embryonic axial patterning, and is lethal. A key factor in translational repression is Bruno (Bru), which binds to regulatory elements in the osk mRNA 3′ UTR. After posterior localization of osk mRNA, repression by Bru must be alleviated. Here we describe an in vivo assay…

    by Jing-Ti Deng, Xiu-Ling Wang, Yong-Xiang Chen, Edward R. O’Brien, Yu Gui, Michael P. Walsh Rho-associated kinase (ROCK) and zipper-interacting protein kinase (ZIPK) have been implicated in diverse physiological functions. ROCK1 phosphorylates and activates ZIPK suggesting that at least some of these physiological functions may require both enzymes. To test the hypothesis that sequential activation of ROCK1 and ZIPK is commonly involved in regulatory pathways, we utilized siRNA to knock down ROCK1 and ZIPK in cultured human arterial smooth muscle cells (SMC).

It was taking the place of the paper version that accountants manually edited, added to, and taped together. From the original article, a fine use of quotation marks: All this powerful scenario-testing machinery right there on the desktop induces some people to experiment with elaborate models. They talk of "playing" with the numbers, "massaging" the model. Computer "hackers" lose themselves in the intricacies of programming; spreadsheet hackers lose themselves in the world of what-if.

    Michael Beuoy's win probability model plotted on FiveThirtyEight starts all NBA teams at a 50% chance of winning. Then the probability of winning a game increases and decreases from there. However, practically speaking, we know something about the teams before each game, and we don't give even chances to the worst and best team at the zero-minute mark. So Todd Schneider took a different approach to minute-by-minute win probability — from a gambling perspective. Each line in the time series starts closer to the end probability as gamblers wager based on what they think the final outcome…
  • Every NBA team’s chances of winning, by game minute

    26 Feb 2015 | 3:33 am
    Michael Beuoy made a win probability model for NBA teams and games, based on play-by-play data from 2000 to 2012. The basic calculator lets you punch in the game state, such as time left and the score difference, and it spits out the probability of a win. Or, for a team-centric view, you can see the chart from Beuoy and Allison McCann for FiveThirtyEight, which plots the average probability using the same model. Steady rise means a steady pull towards a win, whereas spikes and steeper, positive slopes mean a tendency towards scoring spurts. Tags: basketball, FiveThirtyEight

  • First detailed microscopy evidence of bacteria at the lower size limit of life

    27 Feb 2015 | 2:40 pm
    Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley. The existence of ultra-small bacteria has been debated for two decades, but there hasn't been a comprehensive electron microscopy and DNA-based description of the microbes until now.

  • Big Bang, Deflated? Universe May Have Had No Beginning

    28 Feb 2015 | 6:00 am
    If a new theory turns out to be true, the universe may not have started with a bang. In the new formulation, the universe was never a singularity, or an infinitely small and infinitely dense point of matter. "Our theory suggests that the age of the universe could be infinite," said study co-author Saurya Das, a theoretical physicist at the University of Lethbridge in Alberta, Canada. The new concept could also explain what dark matter — the mysterious, invisible substance that makes up most of the matter in the universe — is actually made of, Das added.
  • Rare Roman Tombstone Discovered in England

    28 Feb 2015 | 5:09 am
    A 1,800-year-old tombstone was discovered at a Roman cemetery in England this week. Because of its inscription, archaeologists know who was buried in the grave: a 27-year-old woman named Bodica. "It's incredibly rare," Neil Holbrook, of Cotswold Archaeology, told Live Science. For the last two months, Holbrook's team has been excavating a Roman cemetery just outside the ancient city walls of Cirencester, a town in Gloucestershire, to make way for the construction of a new office park.

    27 Feb 2015 | 2:40 pm
    The death of "Star Trek" actor Leonard Nimoy has prompted an outpouring of condolences and heartfelt reflection from astronauts, scientists, celebrities and even President Barack Obama. People from around the world flocked to social media  to honor Leonard Nimoy — made famous by his portrayal of the logical Vulcan Spock on the original "Star Trek" TV show — after his death was reported earlier today (Feb. 27). "Long before being nerdy was cool, there was Leonard Nimoy," Obama said in a statement released today. Cool, logical, big-eared and level-headed, the…
  • Leonard Nimoy, Spock on 'Star Trek,' Dies at 83

    27 Feb 2015 | 11:12 am
    Actor Leonard Nimoy, who portrayed the iconic logical Vulcan Spock on TV's "Star Trek" and in feature films, has died. Nimoy's career spanned TV, feature films, art and photography, but he was perhaps best known for playing Spock, the logical Vulcan on the starship the USS Enterprise, in "Star Trek." Nimoy died from complications due to "end-stage chronic obstructive pulmonary disease," according to the New York Times, which first reported the actor's death Friday morning (Feb. 27). His idea for Spock's signature Vulcan salute was actually…

    Little chemicalBIG SMELL: Leave it to a pinch of beta-mercaptoethanol to overpower the lab. While not every chemical has such a pungent reminder about where it should be handled (hint: not at the bench), a good rule of thumb is to make use of your chemical fume hood whenever possible! We looked recently at the types of hoods that can be found around your research center (Beginners Guide to Fume Hood and Safety Cabinets). If you’re planning to run an experiment in one, here are a few tips to help you prepare: 1. Check the pressure gauge Fume hoods run 24/7/365 except during maintenance.

  • Quantifying Your NGS Libraries

    James Hadfield
    20 Feb 2015 | 2:04 pm
    If you want to get the maximum yield and quality from your next-generation sequencing experiment then you are going to need to make sure each of the libraries you produce is carefully quantified ready for pooling and/or loading onto a flow cell. If the quantification goes wrong you’ll get a bad balance of samples within your pool, and if the loading goes wrong you might get no data at all! There are three places you really need to consider careful quantification in next-generation sequencing workflows: your input DNA/RNA, mixing libraries to create multiplex pools, and flow-cell or PGM-chip…

  • Bees have false memories too – this might help explain how our own form

    Tibi Puiu
    28 Feb 2015 | 3:00 am
    Memories aren't infallible - even for those with photographic memory - so, more often than not, they'll seem fuzzy. And the older these get, the fuzzier they're recalled. Mixing names, faces and events in your head can sometimes be embarrassing, but at least we're not alone. Seems like bees have false memories too, according to a study made by British researchers at Queen Mary University of London. Previously, false memories had been induced in other animals, like mice, but this is the first time natural false memories have been shown to happen. Research like this might help us, in time,…

    One of the prime arguments climate change skeptics throw about is how surface temperatures have remained more or less constant for the past 15 years, hence there is no man-made global warming – it’s all a sham, a conspiracy to keep scientists busy with gratuitous grants and fill Al Gore’s pockets.

    A complex artificial intelligence program developed by DeepMind, a London-based company which was acquired by Google last year for $400 million, mastered classic ATARI video games, like Breakout, Video Pinball, and Space Invaders. It was so effective that it outperformed professional game testers in 29 of the 49 games it tried out. As is the case with such demonstrations, there's more to it than just humiliating humans. The same algorithms could be used to develop and improve autonomous robots or self-driving cars.

    Some technologies flash in the pan so quickly they hardly leave a trace (Google Glass anyone?); while others seem to stick around long past their use by date. And still other creations appear to be gone for good, only to make a comeback within a niche—and likely nostalgic—community. We set out to explore the rhymes and reasons behind these ebbs and flows of technological innovation and obsolescence. First we go to a place where digital nostalgia is alive and well: a vintage video arcade outside of Chicago. Reporter Colleen Pellissier tells the story of one man who dedicates his life to…

    You wouldn’t know a limpet had teeth from looking at it. These soft, squishy sea snails cling to rocks and scrape algae into their mouths, which means their teeth need to be stronger than rock. Last week, a paper in the Royal Society’s journal Interface published the results of a limpet tooth stress test. It turns out that these teeth are the strongest biological material on the planet. (We wrote about graphene a few months ago, which is one of the strongest human-made materials.)The study reports that the teeth can take between 3.0 to 6.5 GPa (gigapascals) of stress before failing.

The former NASA roboticist pointed out that the most incredible thing about the Rosetta mission wasn’t its unprecedented proximity to a comet, or the decade it took to get there. It was the harpoons used to anchor the Philae lander to the comet.This incongruity between an ancient whaling weapon and an advanced space probe is not only an opportunity for humor, it’s also an example of the unexpected second lives of some…

Twenty-first-century technology is mostly black boxed, its workings invisible and unknowable by most.Our upcoming podcast on technology and obsolescence (due out on iTunes and our website February 18) inspired me to read Nicholas Carr’s The Glass Cage: Automation and Us.

And it's easy to make, in its various forms.Cornflour Slime:All you need is cornflour (made from actual corn - maize - not the "wheaten" version you can get in Australia, which is made from wheat), water, some colouring, a bowl and a spoon. The process is: Pour cornflour into a bowl, Stir in small amounts of water until the cornflour becomes a thick paste. I prefer to have the water coloured at this point, as it helps to more effectively spread the colour throughout the slime.And that's it. Try stirring the slime slowly (should be easy) and then quickly (should be almost…

  • Science for kids - detergent powered boats

    9 Jan 2015 | 8:38 pm
    This is an easy one, assuming you occasionally clean your dishes. You just need some bread ties, water and detergent. The video is a little unimpressive, but you could dress the bread ties up to make them look like boats. Essentially, the detergent is breaking the surface tension of the water, and if you break the surface tension behind the bread tie, the tension in front of the tie pulls it forward. Detergents are surfactants, which means they have a polar end (which is attracted to water) and a non-polar end (which is attracted to oil and grease). This is how detergents (and soaps) bond to…

    One of the biggest mysteries in galaxy evolution is the fate of the compact massive galaxies that roamed the early Universe. “When our Universe was young, there were lots of compact, elliptical-shaped galaxies containing trillions of stars,” says Alister Graham of Swinburne University of Technology. “Due to the time it takes for light to travel across the vastness of space, we see these distant galaxies as they were in our young Universe. However in the present-day Universe very few such spheroidal stellar systems have been observed.” Closer to home, the central spheroid of our own…

    If temperatures continue to rise in New York’s Oneida Lake, it’s likely bye bye to the burbot fish there, according to a release from Cornell University. In addition to the local extinction of the cold water fish species, the shallow lake will become more vulnerable to algal blooms and lower oxygen levels, researchers say. The predictions are being made following a study by scientists at Cornell who modeled the lake’s future using data on stream temperature and discharge, weather and lake temperature at varying depths.

    24 Feb 2015 | 7:57 am
    Scientists at the University of Georgia have launched a new lake monitoring effort called CyanoTRACKER, according to a release from the school. The work is funded by the National Science Foundation and will rely on crowdsourced data to spot lakes in Georgia at risk from harmful algal blooms. Much of the data collection will rely on social media sites like Twitter, Facebook and Instagram that citizen scientists in the state can use to help identify blooms. Those online venues will complement current remote sensing efforts of cyanobacteria outbreaks in Georgia, as well as take advantage of…
  • New Freshwater Bacteria Implicated In Eagle Deaths

    Scientists at the University of Georgia have identified for the first time a toxic cyanobacterium that has been implicated in the deaths of once-endangered American bald eagles, according to a release from the school. The bacteria, they say, can be found on the leaf bottoms of invasive hydrilla that makes its home in most all freshwater bodies of the U.S. The researchers have studied the bacterium for some time but only recently determined that it was an undiscovered species in a new genus. “This new species has a growth form and gene sequence so unusual that it does not fit into any of the…

    The amount of ice cover on Lake Michigan has nearly doubled in the past seven days, according to data from the Great Lakes Environmental Research Laboratory. But it still has a ways to go to catch up with Lake Erie, which sits at nearly 96 percent covered. “It’s interesting to note that this year Lake Erie is about 95.5 percent ice covered. Last year it was about 92 percent ice covered, so a little bit more this year,” said George Leshkevich, physical scientist at the GLERL to WTMJ Radio in Wisconsin. “It’s the same with Lake Ontario, which is 36 percent ice covered…and in…
  • Tropical Mountain Lakes Can’t Escape Climate Change

    12 Feb 2015 | 7:18 am
    Researchers from Queen’s University made trips in 2011 to study three mountain lakes near Cuenca, Ecuador. Even though the lakes sit far away from human activity, the scientists found that the water bodies can’t escape the effects of climate change, according to a study published during February 2015 in the open-access journal PLOS ONE. All three of the lakes reside in the Andes Mountains and are part of a chain of 270 lakes that sit in El Cajas National Park. Those hundreds of lakes, as well as lands around them, were set aside because of their importance culturally and historically…

    Several years ago, writer Ann Morgan noticed that she didn’t read much literature from countries outside of the United Kingdom and United States — and had yet to dive into stories from around the globe. From this realization, her blog, A Year of Reading the World, was born. You can read about Ann’s journey in her new book, Reading the World: Confessions of a Literary Explorer, available now in the UK. (The US version, The World Between Two Covers, will be released on May 4.) I chatted with Ann about the blog-to-book journey and her experience of reading and blogging about…

It is a popular tool used by weather presenters to make you feel worse about going outside when it’s cold and windy! Seriously, if, for example, the reported air temperature (as measured by a thermometer housed in one of those white boxes with the grills, a Stevenson screen, or shelter) is -7 Celsius and the wind is blowing at a steady 8 km/h, then it will “feel” like it’s -11 Celsius.

      Combustion, which is simply the burning of something, is a rather complex chemical process. We rely quite heavily on combustion technologies for energy. For example, we burn gasoline to power our cars; we often burn oil or gas in home heating systems; and power plants usually burn coal, oil or natural gas to generate electricity. Many families, particularly in the developing world, burn wood and other biomass to cook food and heat their homes. However, burning wood and other solid fuels produces a lot of smoke, which is harmful to health and the environment. In fact, the World Health…

  • Growth signal can influence cancer cells’ vulnerability to drugs, study suggests

    27 Feb 2015 | 8:11 am
    In theory, a tumor is an army of clones, made up of many copies of the original cancerous cell. But tumor cells don’t always act like duplicates, and their unpredictable behavior can create problems for treatment. For while some cells within a tumor succumb to anti-cancer drugs, others may survive to bring the cancer back to life once therapy has ended.

    What will you discover? (Photo Credit: Courtesy of Grand Teton National Park Service, via Wikimedia Commons) Project: iNaturalist.org When we were children, we naturally spent a great deal of time exploring the world around us. Everything was a delight. The robins in our backyard were new to us; the spiders in the houseplants were fascinating; the squirrels at the park were endlessly entertaining.

All of it to reduce friction – you get the idea… Now bring a strong magnet towards it, you’ll repel the grape. Try doing it with the other pole of the magnet. It still goes away. So are grapes magnetic? Well, intrinsically the grapes are not magnetized, but when you bring a strong magnet closer, it gets magnetized in the field of this magnet. Stronger  the magnet, more is the magnetization.

    By Anupum Pant “Imagine an alien that could float through space with a giant brain shaped like a doughnut, eight arms on its head and three hearts pumping blue blood.” This thing that I’m talking about is no alien. It’s the cuttlefish – A flesh eating creature that can hide from predators pretty well. Of course octopus does it well, cuttle fish does it better!

  • As You Know Bob – I Dont Exist

    Brett Davidson
    28 Feb 2015 | 11:00 am
    As You Know Bob the nature of consciousness is entrenched in mystery, leading some philosophers to conclude, "I don't exist." As you know Bob, I don’t exist – but I am, for all intents and purposes, immortal. You must have wondered many times of course just what is meant by the word ‘self’. Certainly there is conscious awareness, but where does that awareness stand? What is its platform? Personality, as we understand it, is a combination of memory and action – declarative memory of the sort that tells you that Paris is the capital of France and it is procedural memory that enables…
  • The Science Behind The Munchies

    Andrew Seel
    28 Feb 2015 | 9:00 am
    The munchies cause cannabis enthusiasts everywhere to reach for tasty snacks and scientists have identified why. It is a mystery that has perplexed cannabis enthusiasts since they gathered on the muddy fields of Woodstock—why does tetrahydrocannabinol (THC), the active compound in cannabis, cause smokers bellies to rumble? The answer is quite simple, and will come as no surprise to smokers who often find themselves halfway through a jar of Nutella in a comatose state. THC replaces naturally occurring chemicals in the brain, causing dramatic changes that enhance the sense of taste and smell.

    In Mind Job privacy no longer exists, and thoughts are recorded for AI machines to pass judgment, but one detective searches for justice. Mind Job It was past midnight when Detective Jensen received a thought from the Mental Larceny Division. A mind jobber had been busted. The huge cache of stolen memories would have to be read, as well as the jobber's mind. The download would take days, but would likely lead to breakthroughs in several of her cases. She thought about what particular memories, people and places she was looking for more evidence on, and the computer recorded all faithfully.

    The Amazon rainforest is in the northeast of South America and is a dense humid jungle, while the Sahara Desert is a mass of a nearly uninterrupted band of sand that lays on the northern part of Africa. When strong winds move across the Sahara, a huge cloud of dust rises in the air, then stretches between each of the continents. That is what connects the two—dust, lots of it. A NASA satellite for the first time has quantified in three dimensions the dust that is moving across the Atlantic.

Was this an extraterrestrial anomaly or satellite in the western skies? People could see it from Arizona to Canada.

    Edy Hardjo es el encargado de esta galería de fotos donde nos demuestra que los juguetes no son solo para los niños, y pone a nuestros superheroes favoritos en posiciones divertidas y en ocasiones bastante comprometedoras.Antes de poner las figuras en las posiciones correctas, remueve algunos de sus accesorios y en ocasiones utiliza photoshop para darle un toque un poco más realista. Para alguien que toma fotografías solo como hobbie ciertamente realiza un trabajo genial.En un entrevista dijo "Utilizo mi experiencia como fuente diaria de inspiración... Todo lo que hago es…

    I’m writing this post from a Bangkok-Dubai flight. It’s a 6 hours trip in a brand new giant Airbus 380. We have in-flight Internet. Slow, but functional. This is the way to go. Economy is stagnated in most of the world. There are micro actions that could probably help if not revert, at least to alleviate this situation. One of them is to reduce dead times when people can’t produce or consume. Airports and flights are a deep holes of such dead times. In-flight Internet is still rare. Same about phone calls. Most of time, it isn’t due to technical issues. It’s…

    It’s one month since we watched perplexed the terrorist attacks at the Charlie Hebdo. What have we learned since then? Are we still Charlie? As you probably know, the cover of the first post-attack edition of the Charlie Hebdo featured a caricature of Mohamed, the prophet, dropping a tear, holding a “Je suis Charlie” sign, and standing under the phrase “Tout est pardonné” (Everything is forgiven). Over that cover, thousands protested in Islamic counties, Cristian churches were burned, a dozen died somewhere in Africa. This made me think of how amazing the power…
  • The Crooked Lines of Mr. Newton

    Newton created his mechanics as something between an anti-atheist manifest and a treat of theology. Poor Sir Isaac, he had no idea he was gifting civilization with a major contribution to a godless world. Most of people think of space as an empty volume where things stand. Take all things out, the space would still be there. René Descartes wasn’t most of people. For him, space was only a relation between things, with no existence whatsoever. Thus, motion is always relative, as there is no absolute space framing the world. Moreover, Descartes believed that the universe was composed of…

    In the last post, I wrote a short fictional dialogue, where two colleagues, Edwin and Friedrich, discussed possible scenarios for the future of the universe. In this post, I want to come back to that topic to explore a bit of the science behind those ideas. 1. Cyclic Universe and Eternal Return The first scenario, proposed by Friedrich, was a cyclic universe with eternal return. Eternal return was a relatively popular concept in the 19th century. We find Nietzsche, Boltzmann, Poincaré, and other less shinning names–Dühring, Blanqui, Le Bon, Heine–speculating about it. The idea…
