Nobel keeps its kudos but award from Yuri Milner and friends is fairer
The Breakthrough Prize in Life Sciences gave away $33m to eleven winners, all in one fell swoopThe annual science prizes set up by Yuri Milner over the past year are worth $3m apiece. That is more than twice the cash that accompanies a Nobel prize, the awards with which they are inevitably compared. But no one goes into science for the money. Kudos and tenure? Yes.And this is where the prizes differ. The Nobel prize has a cachet that will not be surpassed in a hurry. For all its faults, and sometimes, because of them, the prizes are seen as the pinnacle of a scientific career. Unlike the Milner prizes, there is a limit on ...

Could Another Chelyabinsk-Scale Meteor Sneak Up on Us?
[caption id="attachment_11024" align="alignleft" width="300" caption="Credit: ESA"] [/caption]When a 17-meter asteroid barreled into Earth's atmosphere over central Russia on February 15, releasing a powerful shock wave that injured more than 1,000 people, many observers wondered how such a momentous event could arrive unheralded. The fact is, the object that exploded in a fireball over Chelyabinsk, releasing hundreds of kilotons of energy , was small potatoes. There may be millions of comparably sized objects in the inner solar system, only a small fraction of which have been discovered. The searches to date have been f...

Can Ethanol from Corn Be Made Sustainable?
A new plant is rising from the fields around Emmetsburg, Iowa--one that will ferment into ethanol the cobs, stems and husks of corn from nearly 50,000 hectares of farmland. Such cellulosic ethanol offers a way to get the energy and environmental security benefits of biofuels without disrupting the food supply when the edible corn itself is used. [More]

Geoffrey Coates obituary
Geoffrey Coates, the distinguished organometallic chemist, has died aged 95. In his academic research, Geoffrey worked with hazardous air- and moisture-sensitive compounds containing metal-carbon or metal-hydrogen bonds. Their study helped our understanding of chemical bonding (and of safety issues), and led to new catalysts, semiconducting materials and reagents for use in the chemical, oil, plastics and pharmaceutical industries.His authoritative book on organometallic compounds, which grew from a slim monograph to a comprehensive, two-volume third edition in a decade, greatly helped generations of students and researche...

Upstream Battle: Fishes Shun Modern Dam Passages, Contributing to Population Declines
Fishes may not need bicycles, as Gloria Steinem once suggested , but elevators and ladders can come in handy. Since the 1960s the Federal Energy Regulatory Commission has required dam builders to install state-of-the-art fish passages on public waterways to help shad, salmon and other species make their annual spring journeys upriver to spawn. Hydropower dams have built inclined water channels called ladders that fishes could swim through or elevators that use caged buckets to lift fish up and over the dam. Although these passages are monitored to ensure that fishes use them, a new study by ecologists and economists shows...

What do TV screens, bullet-proof vests and soap all have common? | Athene Donald

And how does they relate to why soap is effective at cleaning us? If you know what a liquid is (key properties include that it flows and changes shape to fit the container in which it sits), and have a memory of copper sulphate crystals at the bottom of a test-tube from school chemistry lessons, the idea of a liquid crystal may seem a bit odd. It is, however, a well-d...

Everyday chemicals 'pose threat to health'
Conclusion The media headlines, while a little sensationalist, did reflect the WHO/UNEP conclusion that EDCs do present a threat to human health, and that measures to reduce this threat should be considered. The report stops short of saying that EDCs definitely cause specific conditions, but it described the evidence as very strong in some cases. Ultimately, this report tackles risks on a nationwide scale, so it didn't predict individual risk from exposure to EDCs. This will vary tremendously from person to person. Similarly, it did not deal with how we can reduce our exposure to EDCs, or whether this is advisable. Inste...

Antimicrobial peptides from plants: stabilization of the γ core of a tomato defensin by intramolecular disulfide bond
Cysteine‐containing antimicrobial peptides of diverse phylogeny share a common structural signature, the γ core, characterized by a strong polarization of charges in two antiparallel β sheets. In this work, we analyzed peptides derived from the tomato defensin SolyC07g007760 corresponding to the protein γ core and demonstrated that cyclization of the peptides, which results in segregation of positive charges to the turn region, produces peptides very active against Gram negative bacteria, such as Salmonella enterica and Helicobacter pylori. Interestingly, these peptides show very low hemolytic activity and thus repres...

Individual differences in mental rotation: what does gesture tell us?
Abstract Gestures are common when people convey spatial information, for example, when they give directions or describe motion in space. Here, we examine the gestures speakers produce when they explain how they solved mental rotation problems (Shepard and Meltzer in Science 171:701-703, 1971). We asked whether speakers gesture differently while describing their problems as a function of their spatial abilities. We found that low-spatial individuals (as assessed by a standard paper-and-pencil measure) gestured more to explain their solutions than high-spatial individuals. While this finding may seem surprising, fine...

Twisting space: are rigid and non-rigid mental transformations separate spatial skills?
Abstract Cognitive science has primarily studied the mental simulation of spatial transformations with tests that focus on rigid transformations (e.g., mental rotation). However, the events of our world are not limited to rigid body movements. Objects can undergo complex non-rigid discontinuous and continuous changes, such as bending and breaking. We developed a new task to assess mental visualization of non-rigid transformations. The Non-rigid Bending test required participants to visualize a continuous non-rigid transformation applied to an array of objects by asking simple spatial questions about the position of...
