Humans have a mighty bite
The robust jaws and formidable teeth of some of our ancestors and ape cousins may suggest that humans are wimps when it comes to producing a powerful bite: but a new study has found the opposite is true. The surprise findings suggest that early modern humans did not necessarily need to use tools and cooking to process high-nutrient hard foods, such as nuts, but may have lost an ability to eat very tough items, such as tubers or leaves.

Research from Rensselaer Polytechnic Institute professor offers clues to Alzheimer's disease
An organic compound found in red wine -- resveratrol -- has the ability to neutralize the toxic effects of proteins linked to Alzheimer's disease, according to research led by Rensselaer Professor Peter M. Tessier. The findings, published in the May 28 edition of the Journal of Biological Chemistry, are a step toward understanding the large-scale death of brain cells seen in certain neurodegenerative diseases.

Growing brain is particularly flexible
Science has long puzzled over why a baby's brain is particularly flexible and why it easily changes. Is it because babies have to learn a lot? A group of researchers from the Bernstein Network Computational Neuroscience, the Max Planck Institute for Dynamics and Self-Organization in Göttingen, the Schiller University in Jena and Princeton University have now put forward a new explanation: Maybe it is because the brain still has to grow.

VLT detects first superstorm on exoplanet
Astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied "hot Jupiter" HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side of the planet. The observations also allow another exciting "first" -- measuring the orbital speed of the exoplanet itself, providing a direct determination of its mass.

Separation between Neanderthal and Homo sapiens might have occurred 500,000 years earlier
Spanish scientists have analyzed the teeth of almost all species of hominids that have existed during the past 4 million years. Thus, they achieved to identify Neanderthal features in ancient European populations. Dental fossils suggest that the separation occurred at least a million years ago, while DNA-based analyses suggest that this occurred much later.

Polio outbreak in Tajikistan is cause for alarm
The rapidly growing polio outbreak in Tajikistan raises serious concerns that the disease could spread to other regions in the world, states an editorial in CMAJ (Canadian Medical Association Journal). It is imperative that health agencies attempt to limit further spread by ensuring high vaccination rates.

Evidence that nanoparticles in sunscreens could be toxic if accidentally eaten
Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death. Their study is in ACS' Chemical Research in Toxicology, a monthly journal.

Nematodes vanquish billion dollar pest
Diabrotica virgifera virgifera beetle larvae (known as western corn rootworm) wreak havoc on maize, causing an estimated $1 billion of damage every year to US agriculture. Knowing that Heterorhabditis bacteriophora nematodes kill the pest, researchers at the University of Neuchatel, Switzerland, have successfully improved the nematode's response to a chemical, (E)-beta-caryophyllene, released by damaged maize roots, to attract the nematodes directly to the pest in a bid to produce an environmentally safe pesticide.

Behavior breakthrough: Like animals, plants demonstrate complex ability to integrate information
A University of Alberta research team has discovered that a plant's strategy to capture nutrients in the soil is the result of integration of different types of information. Cahill found plants also have the ability to integrate information about the location of both food and competitors. As a result, plants demonstrate unique behavioral strategies to capture soil resources.

Antihypertensive drugs may protect against Alzheimer's disease
Researchers at Mount Sinai School of Medicine have found that the drug carvedilol, currently prescribed for the treatment of hypertension, may lessen the degenerative impact of Alzheimer's disease and promote healthy memory functions. The new findings are published in two studies in the current issues of Neurobiology of Aging and the Journal of Alzheimer's Disease.

Brown team finds widespread glacial meltwater valleys on Mars
A research team led by Brown University has documented dozens of channels carved by melted water from glaciers located in the midlatitude region of Mars. The glaciofluvial valleys were carved in Mars' most recent epoch, the team reports, supporting the idea that the Red Planet was home to diverse watery environments in its recent past. Results are published in Icarus.
