What's New in Science - More news
  • Solar-cell efficiency improved with new polymer devices
    New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer -- a type of large molecule that forms plastics and other familiar materials -- which improved the efficiency of solar cells. The group also determined the method by which the pol...
  • Climate Change: Dwindling wind may tip predator-prey balance
    Rising temperatures and shifting precipitation patterns may get the lion?s share of our climate change attention, but predators may want to give some thought to wind, according to a zoologist?s study, which is among the first to demonstrate the way ?global stilling? may alter predator-prey relations...
  • Better way to track emerging cell therapies using MRIs
    The first human tests of using a perfluorocarbon (PFC) tracer in combination with non-invasive magnetic resonance imaging to track therapeutic immune cells injected into patients with colorectal cancer have been reported by scientists.
  • Domestic violence likely more frequent for same-sex couples
    Domestic violence occurs at least as frequently, and likely even more so, between same-sex couples compared to opposite-sex couples, according to a new review of research. Abuse is underreported in same-sex couples due to the stigma of sexual orientation, researchers note.
  • Possible 6,800 new Ebola cases this month, research predicts
    A possible 6,800 new Ebola cases this are predicted this month, as suggested by researchers who used modelling analysis to come up with their figures. The rate of new cases significantly increased in August in Liberia and Guinea, around the time that a mass quarantine was put in place, indicating th...
  • Using genetic screening to improve Korean white wheat
    Korean white winter wheat is particularly susceptible to preharvest sprouting, according to researchers. Researchers have identified proteins that are differentially expressed in tolerant cultivars, with the goal of breeding more resistant varieties that can help increase wheat production in Korea.
  • Pathway that contributes to Alzheimer's disease revealed by research
    A defect in a key cell-signaling pathway has been discovered that researchers say contributes to both overproduction of toxic protein in the brains of Alzheimer?s disease patients as well as loss of communication between neurons ? both significant contributors to this type of dementia.
  • Genetically driven gut feelings help female flies choose a mate
    Even among flies, mating is a complicated ritual. Their elaborate, and entirely innate, courtship dance combines multiple motor skills with advanced sensory cues. Now, researchers have determined that the Abdominal-B (Abd-B) gene, previously known as the gene that sculpts the posterior parts of the ...
  • Fingertip sensor gives robot unprecedented dexterity
    Researchers have equipped a robot with a novel tactile sensor that lets it grasp a USB cable draped freely over a hook and insert it into a USB port.
  • Gene responsible for traits involved in diabetes discovered
    A new gene associated with fasting glucose and insulin levels in rats, mice and in humans, has been discovered by researchers. 29 million Americans have diabetes -- more than nine percent of the total population. It is the 7th leading cause of death, and experts estimate diabetes is an underreported...
  • A refined approach to proteins at low resolution
    Crystals of membrane proteins and protein complexes often diffract to low resolution owing to their intrinsic molecular flexibility, heterogeneity or the mosaic spread of micro-domains. At low resolution, the building and refinement of atomic models is a more challenging task. The deformable elastic...
  • Soft robotics 'toolkit' features everything a robot-maker needs
    A new resource provides both experienced and aspiring researchers with the intellectual raw materials needed to design, build, and operate robots made from soft, flexible materials. With the advent of low-cost 3-D printing, laser cutters, and other advances in manufacturing technology, soft robotics...
  • Reflected smartphone transmissions enable gesture control
    Engineers have developed a new form of low-power wireless sensing technology that lets users "train" their smartphones to recognize and respond to specific hand gestures near the phone.
  • Don't cry wolf: Drivers fed up with slowing down at inactive roadwork sites
    Drivers are frustrated at slowing down at inactive roadwork sites are ignoring reduced speed limits, an Australian study has found. The survey involved more than 400 people who were asked to estimate their speed for a range of different roadwork site scenarios, some of which were inactive sites and ...
  • Hadrosaur with huge nose discovered: Function of dinosaur's unusual trait a m...
    Call it the Jimmy Durante of dinosaurs -- a newly discovered hadrosaur with a truly distinctive nasal profile. The new dinosaur, named Rhinorex condrupus by paleontologists, lived in what is now Utah approximately 75 million years ago during the Late Cretaceous period.
  • Simple test can help detect Alzheimer's before dementia signs show, study shows
    A simple test that combines thinking and movement can help to detect heightened risk for developing Alzheimer's disease in a person, even before there are any telltale behavioural signs of dementia, researchers report, adding that the findings don't predict who will develop Alzheimer's disease, but ...
  • Graphene sensor tracks down cancer biomarkers
    An ultrasensitive biosensor made from the wonder material graphene has been used to detect molecules that indicate an increased risk of developing cancer. The biosensor has been shown to be more than five times more sensitive than bioassay tests currently in use, and was able to provide results in a...
  • Environmental pollutants make worms susceptible to cold
    Some pollutants are more harmful in a cold climate than in a hot, because they affect the temperature sensitivity of certain organisms. Now researchers have demonstrated how this happens, and it can help us better predict contamination risks, especially in the Arctic.
  • Computers 1,000 times faster? Quick-change materials break silicon speed limi...
    Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.
  • Some patients with advanced, incurable cancer denied palliative care
    Many patients with advanced, incurable cancer do not receive any palliative care, reveals new research. The findings are astonishing as they come at the same time as 15 new oncology centres in Europe, Canada, South America and Africa are being awarded the title of 'ESMO Designated Centre of Integrat...
