Penn biologists show how plants turn off genes they don't need
New research led by University of Pennsylvania biologists and published this week in the journal Nature Genetics has identified small sequences in plant DNA that act as signposts for shutting off gene activity, directing the placement of proteins that silence gene expression.

Hidden river once flowed beneath Antarctic ice
Using the most precise seafloor maps ever created of Antarctica's Ross Sea, Rice University researchers have discovered a long-dead river system that once flowed beneath Antarctica's ice and influenced how ice streams melted after Earth's last ice age. The research appears online this week in Nature Geoscience.

Plants under heat stress must act surprisingly quickly to survive
In The Plant Cell, UMass Amherst molecular biologist Elizabeth Vierling reports that heat-stressed plants not only need to produce new proteins to survive the stress, they need to make them right away. 'We found that a delay of even six hours of new protein translation will inhibit optimal growth and reproduction. The plants might not outright die, but they are severely impaired without the rapid synthesis of these new proteins.'

Polarization for controversial scientific issues increases with more education
A commonly proposed solution to help diffuse the political and religious polarization surrounding controversial scientific issues like evolution or climate change is education. However, Carnegie Mellon University researchers found that the opposite is true: people's beliefs about scientific topics that are associated with their political or religious identities actually become increasingly polarized with education, as measured by years in school, science classes, and science literacy.

Research reveals 'exquisite selectivity' of neuronal wiring in the cerebral cortex
In a study appearing today in Nature Neuroscience, a team from Cold Spring Harbor Laboratory uses advanced technologies to illuminate the connectivity pattern of chandelier cells, a distinctive kind of inhibitory cell type in the mammalian brain. They reveal for the first time how this candelabra-shaped cell interacts in a highly selective way with hundreds of excitatory cells in its neighborhood, receiving information from some, imparting information to others.

Cholesterol-lowering drugs may fight infectious disease
Duke scientists found a gene variant that affects cholesterol levels also could increase the risk of contracting typhoid fever. A common cholesterol-lowering drug could protect animal models against Salmonella Typhi, the culprit behind the potentially deadly infection. The findings give insight into the mechanisms that govern human susceptibility to infectious disease and point to possible avenues to protect against pathogens -- like Salmonella or Ebola -- whose entry into host cells is regulated by cholesterol.

A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries.

Spoiler alert: Computer simulations provide preview of next week's eclipse
Researchers from Predictive Science Inc. used NASA and National Science Foundation-supported supercomputers to run highly-detailed forecasts of the Sun's corona -- the aura of plasma that surrounds the sun -- at the moment of the eclipse. The team combined data from NASA's Solar Dynamics Observatory, magnetic field maps, solar rotation rates and cutting-edge mathematical models to predict the state of the Sun's surface. The simulations are the largest produced by the group and include new physics.

UMass Amherst computer scientists offer new techniques to measure social bias in software
Brun says, "Unchecked, biases in data and software run the risk of perpetuating biases in society. For example, prior work has demonstrated that racial bias exists in online advertising delivery systems, where online searches for traditionally-minority names were more likely to yield ads related to arrest records. Such software behavior can contribute to racial stereotypes and other grave societal consequences."

Communicating in a foreign language takes emotion out of decision-making
If you could save the lives of five people by pushing another bystander in front of a train to his death, would you do it? And should it make any difference if that choice is presented in a language you speak, but isn't your native tongue? Psychologists at the University of Chicago know communicating in a foreign language matters. In a new study, they take a major step toward understanding why.

Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene
As graphene's popularity grows as an advanced 'wonder' material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the research group of SungWoo Nam, assistant professor of mechanical science and engineering at Illinois, has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide (CO2) in the form of carbonic acid as the electrolyte solution.
