What's New in Science - More news
  • New brain pathways for understanding type 2 diabetes and obesity uncovered
    Researchers have identified neural pathways that increase understanding of how the brain regulates body weight, energy expenditure, and blood glucose levels ? a discovery that can lead to new therapies for treating Type 2 diabetes and obesity.
  • Scalping can raise ticket prices
    A new study finds that resale markets like Craigslist can add value to tickets sold by concert venues and Ticketmaster.
  • New EMS system dramatically improves survival from cardiac arrest
    A new emergency medicine system that sent patients to designated cardiac receiving centers dramatically increased the survival rate of victims of sudden cardiac arrest in Arizona, according to a study. Under the study, 31 hospitals, serving about 80 percent of the state's population, were designated...
  • Designer potatoes on the menu to boost consumption
    A decline in overall potato consumption has breeders working on ?designer? spuds that meet the time constraints and unique tastes of a younger generation.
  • Slow walking speed, memory complaints can predict dementia
    A study involving nearly 27,000 older adults on five continents found that nearly 1 in 10 met criteria for pre-dementia based on a simple test that measures how fast people walk and whether they have cognitive complaints. People who tested positive for pre-dementia were twice as likely as others to ...
  • Anti-inflammatory drug can prevent neuron loss in Parkinson's model
    An experimental anti-inflammatory drug can protect vulnerable neurons and reduce motor deficits in a rat model of Parkinson's disease, a study has shown. The findings demonstrate that the drug, called XPro1595, can reach the brain at sufficient levels and have beneficial effects when administered by...
  • Manipulating key protein in brain holds potential against obesity, diabetes
    A protein that controls when genes are switched on or off plays a key role in specific areas of the brain to regulate metabolism, researchers have found. The research potentially could lead to new therapies to treat obesity and diabetes, since the transcription factor involved ? spliced X-box bindin...
  • Experiences at every stage of life contribute to cognitive abilities in old age
    Early life experiences, such as childhood socioeconomic status and literacy, may have greater influence on the risk of cognitive impairment late in life than such demographic characteristics as race and ethnicity, a large study has found. "These findings are important," explained the lead author of ...
  • Collecting just the right data: Algorithm helps identify which data to target
    Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon and Netflix. But some types of data are harder to collect -- information about geological formations thousands of f...
  • Intensity of hurricanes: New study helps improve predictions of storm intensity
    While predicting the path of hurricanes has gotten better, little has been done to improve predicting a storm's intensity. That is, until now. "The air-water interface -- whether it had significant waves or significant spray -- is a big factor in storm intensity," said one expert involved in a new s...
  • Test increases odds of correct surgery for thyroid cancer patients
    The routine use of a molecular testing panel increases the likelihood of performing the correct initial surgery for thyroid cancer patients by 30 percent, researchers report. "Before this test, about one in five potential thyroid cancer cases couldn't be diagnosed without an operation to remove a po...
  • Magnets for fusion energy: High-temperature superconductor achieves new world...
    Scientists have achieved an electrical current of 100,000 amperes, which is by far the highest in the world, by using the new idea of assembling the state-of-the-art yttrium-based high-temperature superconducting tapes to fabricate a large-scale magnet conductor.
  • Why do men prefer nice women? Responsiveness and desire
    Does responsiveness increase sexual desire in the other person? Do men perceive responsive women as more attractive, and does the same hold true for women's perceptions of men? A recent study undertook to answer those questions.
  • New system to detect mercury in water systems
    A new ultra-sensitive, low-cost and portable system for detecting mercury in environmental water has been developed by researchers. "The promising sensing performance of this system along with its cost-competiveness and portability make it an excellent potential alternative to current analytical tec...
  • Nanoparticle 'alarm clock' tested to awaken immune systems put to sleep by ca...
    Researchers are exploring ways to wake up the immune system so it recognizes and attacks invading cancer cells. One pioneering approach uses nanoparticles to jumpstart the body?s ability to fight tumors. Nanoparticles are too small to imagine. One billion could fit on the head of a pin. This makes t...
  • Monitoring rise and fall of the microbiome
    Close analysis of bacteria in the human digestive tract reveals links to diet and other lifestyle factors, researchers report. Trillions of bacteria live in each person's digestive tract. Scientists believe that some of these bacteria help digest food and stave off harmful infections, but their role...
  • Total darkness at night key to success of breast cancer therapy, study shows
    Exposure to light at night, which shuts off nighttime production of the hormone melatonin, renders breast cancer completely resistant to tamoxifen, a widely used breast cancer drug, says a new study. Melatonin by itself delayed the formation of tumors and significantly slowed their growth, researche...
  • Informed consent: False positives not a worry in lung cancer study
    A false positive screen result -- a screening test in which initial findings of concern for cancer are later found not to be worrisome -- did not cause participants undue anxiety or reduced quality of life, a new study shows. Researchers hypothesize that clear and accurate consent forms prepared pat...
  • Less than 1% of UK public research funding spent on antibiotic research in pa...
    Less than 1% of research funding awarded by public and charitable bodies to UK researchers in 2008?13 was awarded for research on antibiotics, according to new research. The study, which is the first detailed assessment of public and charitable funding to UK researchers focusing on bacteriology and ...
  • Could heart attack patients could be treated more quickly?
    Clinical judgement, combined with an electrocardiogram (ECG) and blood test on arrival, is effective in reducing unnecessary hospital admissions for chest pain, a new study shows. The findings of a research group could potentially make a huge difference to a large number of patients. Researchers ass...
