What's New in Science - More news
  • Building trustworthy big data algorithms
    Much of our reams of data sit in large databases of unstructured text. Finding insights among emails, text documents, and websites is extremely difficult unless we can search, characterize, and classify their text data in a meaningful way. A new algorithm shows better accuracy and reproducibility th...
  • Heavy drinking in middle-age may increase stroke risk more than traditional f...
    Drinking more than two alcoholic beverages a day in middle-age raised stroke risks more than traditional factors such as high blood pressure and diabetes. Heavy drinking in mid-life was linked to having a stroke about five years earlier in life irrespective of genetic and early-life factors.
  • FDA approves first-of-kind device to treat obesity
    The U.S. Food and Drug Administration has approved the Maestro Rechargeable System for certain obese adults, the first weight loss treatment device that targets the nerve pathway between the brain and the stomach that controls feelings of hunger and fullness.
  • Is this the year you join the top one percent? Affluence more fluid than once...
    Here's some good news for the New Year: According to new research, there's a 1 in 9 chance that a typical American will hit the jackpot and join the wealthiest 1 percent for at least one year in her or his working life. And now the bad news: That same research says only an elite few get to stay in t...
  • Complex environments push 'brain' evolution
    Little animations trying to master a computer game are teaching neuroscience researchers how the brain evolves when faced with difficult tasks. Neuroscientists have programmed animated critters that they call 'animats.' The critters have a rudimentary neural system made of eight nodes: two sensors, ...
  • Privacy challenges: Just four vague pieces of info can identify you, and your...
    Just four fairly vague pieces of information -- the dates and locations of four purchases -- are enough to identify 90 percent of the people in a data set recording three months of credit-card transactions by 1.1 million users. If someone had copies of just three of your recent receipts -- or one re...
  • Scientists investigate link between skyrocketing sea slug populations, warmin...
    A team of California scientists believes a far-flung Okenia rosacea bloom -- along with a slew of other marine species spotted north of their typical ranges -- may signal a much larger shift in ocean climate and a strong forthcoming El Niño.
  • Structure of world's largest single cell is reflected at the molecular level
    Biologists used the world?s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
  • Generating Mobius strips of light
    Physicists have experimentally produced Möbius strips from the polarization of light, confirming a theoretical prediction that it is possible for light's electromagnetic field to assume this peculiar shape.
  • New technique for growing high-efficiency perovskite solar cells
    Researchers have revealed a new solution-based hot-casting technique that allows growth of highly efficient and reproducible solar cells from large-area perovskite crystals. The researchers fabricated planar solar cells from pervoskite materials with large crystalline grains that had efficiencies ap...
  • Powerful tool promises to change the way scientists view proteins
    Life scientists now have access to a publicly available web resource that streamlines and simplifies the process of gleaning insight from 3-D protein structures. Aquaria, as it's known, is fast, easy-to-use and contains twice as many models as all other similar resources combined.
  • Erectile dysfunction drugs could protect liver from sepsis-induced damage
    Drugs that are on the market to treat erectile dysfunction could have another use: they might be able to protect the liver from damage caused by sepsis, a systemic inflammatory response to infection, say researchers.
  • In a role reversal, RNAs proofread themselves
    Building a protein is a lot like a game of telephone: information is passed along from one messenger to another, creating the potential for errors. Enzymatic machines proofread at each step, and scientists have uncovered a new quality control mechanism along this path. But in a remarkable role rever...
  • Where did the missing oil go? New study says some is sitting on the Gulf floor
    Some 6 million to 10 million gallons of oil from the BP oil spill are buried in the sediment on the Gulf floor, about 62 miles southeast of the Mississippi Delta, researchers have discovered.
  • CAT scan of nearby supernova remnant reveals frothy interior
    Cassiopeia A, or Cas A for short, is one of the most well studied supernova remnants in our galaxy. But it still holds major surprises. Astronomers have now generated a new 3-D map of its interior using the astronomical equivalent of a CAT scan. They found that the Cas A supernova remnant is compose...
  • First-ever view of protein structure may lead to better anxiety drugs
    When new medicines are invented, the drug may hit the intended target and nullify the symptoms, but nailing a bull's eye -- one that produces zero side effects -- can be quite elusive. New research has, for the first time, revealed the crystal structure of a key protein, TSPO, which is associated wi...
  • Global warming won't mean more storms: Big storms to get bigger, small storms...
    Atmospheric physicists predict that global warming will not lead to an overall increasingly stormy atmosphere, a topic debated by scientists for decades. Instead, strong storms will become stronger while weak storms become weaker, and the cumulative result of the number of storms will remain unchang...
  • Individuals may fail to navigate complex tradeoffs in privacy decision-making
    Researchers have detailed the privacy hurdles people face while navigating in the information age, and what should be done about privacy at a policy level, in a new review.
  • Key element in circadian clock speed discovered
    In a discovery that may lead to new treatments for sleep disorders, jet lag and other health problems tied to circadian rhythms, researchers have identified a determinant of the circadian clock's period.
  • New minimally invasive test identifies patients for Barrett's esophagus scree...
    A new minimally invasive cell sampling device coupled with assessment of trefoil factor 3 expression can be used to identify patients with reflux symptoms who warrant endoscopy to diagnose Barrett's esophagus, according to a new study.
