What's New in Science - More news
  • Family dinners good for teens' mental health, could protect from cyberbullying
    Cyberbullying was associated with mental health and substance use problems in adolescents, a new study shows, but family dinners may help protect teens from the consequences of cyberbullying and also be beneficial for their mental health.
  • Quality of US diet improves, gap widens for quality between rich and poor
    The quality of the US diet showed some modest improvement in the last decade in large measure because of a reduction in the consumption of unhealthy trans fats, but the gap in overall diet quality widened between the rich and the poor.
  • Viewers eat more while watching Hollywood action flick on TV
    Television shows filled with action and sound may be bad for your waistline. TV viewers ate more M&Ms, cookies, carrots and grapes while watching an excerpt from a Hollywood action film than those watching an interview program.
  • Nature's tiny engineers: Corals control their environment, stirring up water ...
    Conventional wisdom has long held that corals -- whose calcium-carbonate skeletons form the foundation of coral reefs -- are passive organisms that rely entirely on ocean currents to deliver dissolved substances, such as nutrients and oxygen. But now scientists have found that they are far from pass...
  • Mom's hormones could make female magpie chicks more adventurous
    Female magpies have been shown to be more adventurous than their male siblings, according to new research. ?The fact that observable differences between the first hatched and last hatched magpie?s behaviors exist indicates that mothers may be able to produce variable traits, possibly through adjusta...
  • Childhood adoption experiences: Effect later in adulthood
    Adoptions have been running at record levels in the UK, with recent figures showing an annual rate of almost 4,000 ? up by 15 per cent ? while Government reforms have attempted to boost the process. Now a researcher is investigating the long-term impact that adoption makes on individuals.
  • Training your brain to prefer healthy foods
    It may be possible to train the brain to prefer healthy low-calorie foods over unhealthy higher-calorie foods, according to new research.
  • Scientists call for investigation of mysterious cloud-like collections in cells
    About 50 years ago, electron microscopy revealed the presence of tiny blob-like structures that form inside cells, move around and disappear. But scientists still don't know what they do -- even though these shifting cloud-like collections of proteins are believed to be crucial to the cell, and ther...
  • How neurons in bats' brains ensure a safe flight
    Bats emit ultrasound pulses and measure the echoes reflected from their surroundings. They have an extremely flexible internal navigation system that enables them to do this. A study shows that when a bat flies close to an object, the number of active neurons in the part of a bat's brain responsible...
  • Greenhouse whitefly: Will the unwanted greenhouseguest make it in the wild?
    Greenhouses have improved the possibilities of invasion of greenhouse whitefly into the wild in the boreal region, new study finds. Genetic analysis sheds new light on the survival of whiteflies in Finland and helps to plan efficient pest management. 
  • Why plants in the office make us more productive
    'Green' offices with plants make staff happier and more productive than 'lean' designs stripped of greenery, new research shows. The team examined the impact of 'lean' and 'green' offices on staff's perceptions of air quality, concentration, and workplace satisfaction, and monitored productivity lev...
  • New tuberculosis blood test in children: reliable, highly specific
    A new blood test provides a fast and accurate tool to diagnose tuberculosis in children, a new proof-of-concept study shows. The newly developed test is the first reliable immunodiagnostic assay to detect active tuberculosis in children. The test features excellent specificity, a similar sensitivity...
  • Invisible blood in urine may indicate bladder cancer
    One in 60 people over the age of 60 who had invisible blood in their urine -- identified by their GP testing their urine -- transpired to have bladder cancer, researchers report. The figure was around half of those who had visible blood in their urine -- the best known indicator of bladder cancer. H...
  • Sniffing-out smell of disease in feces: 'Electronic nose' for rapid detection...
    A fast-sensitive "electronic-nose" for sniffing the highly infectious bacteria C-diff, that causes diarrhea, temperature and stomach cramps, has been developed.
  • Radar and alarm system for construction vehicles
    Researchers have developed an alarm system for construction vehicles with a low-cost radar network that can prevent collisions and improve safety in work environments.
  • Carcinogenic role of protein in liver decoded
    The human protein EGFR controls cell growth. It has mutated in case of many cancer cells or exists in excessive numbers. For this reason it serves as a point of attack for target-oriented therapies. A study group has now discovered that the risk of this protein does not -- as previously assumed -- d...
  • Neurons in human skin perform advanced calculations
    Neurons in human skin perform advanced calculations, previously believed that only the brain could perform. A characteristic of neurons that extend into the skin and record touch, is that they branch in the skin so that each neuron reports touch from many highly-sensitive zones on the skin. Accordin...
  • Plant life forms in the fossil record: When did the first canopy flowers appear?
    Most plant fossils are isolated organs, making it difficult to reconstruct the type of plant life or its ecosystem structure. Botanists have now used leaf vein density, a trait visible on leaf compression fossils, to document the occurrence of stratified forests with a canopy dominated by flowering ...
  • Consequences of teen alcohol, marijuana use studied
    Alcohol use was more commonly reported to compromise relationships with friends and significant others (e.g., boyfriends), researchers studying its consequences report. It was also reported to lead to more regret, particularly among females. Marijuana use on the other hand was more commonly reported...
  • Inhibiting inflammatory enzyme after heart attack does not reduce risk of sub...
    In patients who experienced an acute coronary syndrome event -- such as heart attack or unstable angina -- use of the drug darapladib to inhibit the enzyme lipoprotein-associated phospholipase A2 -- believed to play a role in the development of atherosclerosis -- did not reduce the risk of recurrent...
