  • Record-breaking solar flight reaches Hawaii after 5 nights and days airborne without fuel
    The longest and most difficult leg of the Round the World Solar Flight attempted since last March by Swiss explorers Bertrand Piccard and André Borschberg ended successfully in Hawaii. At the controls of Solar Impulse 2, pilot André Borschberg landed safely in Hawaii after flying 117 hours and 52 minutes over the Pacific Ocean from Japan powered only by the sun.
  • Waiting to harvest after a rain enhances food safety
    To protect consumers from foodborne illness, produce farmers should wait 24 hours after a rain or irrigating their fields to harvest crops, experts say. Rain or irrigation creates soil conditions that are more hospitable to Listeria monocytogenes, which when ingested may cause the human illness Listeriosis. Waiting to harvest crops reduces the risk of exposure to the pathogen, which could land on fresh produce.
  • A 'movie' of ultrafast rotating molecules at a hundred billion per second
    Can you imagine how subnano-scale molecules make an ultrafast rotation at a hundred billion per second? Do the ultrafast rotating subnano-scale molecules show a wave-like nature rather than particle-like behavior? Scientists took sequential 'snapshots' of ultrafast unidirectionally rotating molecules at a hundred billion per second to see for themselves.
  • REM sleep critical for young brain development; medication interferes
    Rapid eye movement or REM sleep actively converts waking experiences into lasting memories and abilities in young brains, reports a new study. The finding broadens the understanding of children's sleep needs and calls into question the increasing use of REM-disrupting medications such as stimulants and antidepressants.
  • Novel DNA repair mechanism brings new horizons
    The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. A group of researchers has discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases.
  • The oceans can’t take any more: Fundamental change in oceans predicted
    Our oceans need an immediate and substantial reduction of anthropogenic greenhouse gas emissions. If that doesn't happen, we could see far-reaching and largely irreversible impacts on marine ecosystems, which would especially be felt in developing countries.
  • Observation of 4?h hyperhydrogen by decay-pion spectroscopy of electro-produced hypernuclei
    An international team has been developing a new experimental technique - the decay-pion spectroscopy of electro-produced hypernuclei since 2011. They have now used this new technique to successfully measure the mass of [4?H], which consists of one proton, two neutrons and one ? particle.
  • Early exposure to cat urine makes mice less likely to escape from cats
    Mice that are exposed to the powerful smell of cat urine early in life do not escape from cats later in life. Researchers have discovered that mice that smell cat urine early in life, do not avoid the same odor, and therefore do not escape from their feline predators, later in life.
  • Supercharging stem cells to create new therapies
    A new method for culturing stem cells has been developed, which sees the highly therapeutic cells grow faster and stronger. Stem cell therapy is showing promising signs for transplant patients, and the IL-17 treated stem cells should be even more effective at preventing and treating inflammation in transplant recipients -- particularly controlling rejection in transplant patients.
  • Greenhouse gas emissions remain primary threat to polar bears
    Greenhouse gas emissions remain the primary threat to the preservation of polar bear populations worldwide. This conclusion holds true under both a reduced greenhouse gas emission scenario that stabilizes climate warming and another scenario where emissions and warming continue at the current pace, according to updated research models.
  • New test could predict arthritis drug failure in patients
    It may be possible to predict early which rheumatoid arthritis patients will fail to respond to the biologic drugs given to treat them, a study of 311 patients has found. These findings could help better manage patients' symptoms.
  • 'Ghost': Technology that leaps out of the screen
    Exciting new technologies, which allow users to change the shape of displays with their hands, promise to revolutionize the way we interact with smartphones, laptops and computers. Imagine pulling objects and data out of the screen and playing with these in mid-air. Today we live in a world of flat-screen displays we use all day – whether it’s the computer in the office, a smartphone on the train home, the TV or iPad on the couch in the evening. The world we live in is not flat, though; it’s made of hills and valleys, people and objects. Imagine if we could use our fingertips to manipulate the display and drag features out of it into our 3D world.

  • New lithium ion battery is safer, tougher, and more powerful
    Lithium ion batteries are a huge technological advancement from lead acid batteries which have existed since the late 1850's.  Thanks to their low weight, high energy density and slower loss of charge when not in use, these have become the preferred choice for consumer electronics.  Lithium-ion cells with cobalt cathodes hold twice the energy of a nickel-based battery and four-times that of lead acid.  Despite being a superior consumer battery, lithium-ion batteries still have some drawbacks.  Current manufacturing technology is reaching the theoretical energy density limit for lithium ion batteries and overheating leading to thermal runaway i.e. "venting with flame" is a serious concern.
  • Millions of children's lives saved through low-cost investments
    More than 34 million children's lives have been saved since 2000 because of investments in child health programs at a cost of as little as $4,205 per child, according to a new analysis. From 2000 to 2014, low- and middle-income country governments spent $133 billion on child health. Donors spent $73.6 billion. The governments saved about 20 million children, and the donors saved an additional 14 million children.
  • Romeo and Juliet roles for banded mongooses
    Female banded mongooses risk their lives to mate with rivals during pack 'warfare' and both males and females have also learned to discriminate between relatives and non-relatives to avoid inbreeding even when mating within their own social group.
  • First trial of gene therapy for cystic fibrosis to show beneficial effect on lung function
    For the first time gene therapy for cystic fibrosis has shown a significant benefit in lung function compared with placebo, in a phase 2 randomized trial. The technique replaces the defective gene response for cystic fibrosis by using inhaled molecules of DNA to deliver a normal working copy of the gene to lung cells.
  • Bioprinted 'play dough' capable of cell and protein transfer
    Scientists have developed a new technique allowing the bioprinting at ambient temperatures of a strong paste similar to 'play dough' capable of incorporating protein-releasing microspheres. The scientists demonstrated that the bioprinted material, in the form of a micro-particle paste capable of being injected via a syringe, could sustain stresses and strains similar to cancellous bone -- the 'spongy' bone tissue typically found at the end of long bones.
  • Seafaring spiders depend on their 'sails' and 'anchors'
    Spiders travel across water like ships, using their legs as sails and their silk as an anchor, according to new research. The study helps explain how spiders are able to migrate across vast distances and why they are quick to colonize new areas.
  • Stopping Candida in its tracks
    Scientists are one step closer to understanding how a normally harmless fungus changes to become a deadly infectious agent.

  • Old World monkey had tiny, complex brain
    The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as Victoriapithecus, first made headlines in 1997 when its 15 million-year-old skull was discovered on an island in Kenya's Lake Victoria. Now, X-ray imaging reveals that the creature's brain was tiny but surprisingly wrinkled and complex. The findings suggest that brain complexity can evolve before brain size in the primate family tree.
  • Studies confirm regorafenib benefit in pre-treated metastatic colorectal cancer

  • Do you really think you're a foodie?
    Think you're a foodie? Adventurous eaters, known as 'foodies,' are often associated with indulgence and excess. However, a new study shows just the opposite -- adventurous eaters weigh less and may be healthier than their less-adventurous counterparts.
  • Long-term memories are maintained by prion-like proteins
    Researchers have uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time.
  • Viral protein in their sights
    A team using electron cryomicroscopy has for the first time revealed at the atomic level the structure of a protein required for viral replication in vesicular stomatitis virus, a virus that is a model for a group of RNA viruses that includes Ebola and other threats to human health.
  • Telomeres linked to origins of idiopathic pulmonary fibrosis
    Researchers have now discovered that telomeres, the structures that protect the chromosomes, are at the origin of pulmonary fibrosis. This is the first time that telomere damage has been identified as a cause of the disease. This finding opens up new avenues for the development of therapies to treat a disease for which there is currently no treatment.
  • Commonly prescribed drugs affect decisions to harm oneself and others
    Healthy people given the serotonin-enhancing antidepressant citalopram were willing to pay almost twice as much to prevent harm to themselves or others than those given placebo drugs in a moral decision-making experiment. In contrast, the dopamine-boosting Parkinson's drug levodopa made healthy people more selfish, eliminating an altruistic tendency to prefer harming themselves over others.
  • What bee-killing mites can teach us about parasite evolution
    An infestation of speck-sized Varroa destructor mites can wipe out an entire colony of honey bees in two to three years if left untreated. Pesticides help beekeepers rid their hives of these parasitic arthropods, which feed on the blood-like liquid inside of their hosts and lay their eggs on larvae, but mite populations become resistant to the chemicals over time.
  • Can autism be measured in a sniff?
    Imagine the way you might smell a rose. You'd take a nice big sniff to breathe in the sweet but subtle floral scent. Upon walking into a public restroom, you'd likely do just the opposite -- abruptly limiting the flow of air through your nose. Now, researchers have found that people with autism spectrum disorder don't make this natural adjustment like other people do.
  • Encryption made easier: Just talk like a parent
    A researcher has created an easier email encryption method – one that sounds familiar to parents who try to outsmart their 8-year-old child. The new technique gets rid of the complicated, mathematically generated messages that are typical of encryption software. Instead, the method transforms specific emails into ones that are vague by leaving out key words.
  • Water to understand the brain
    To observe the brain in action, scientists and physicians use imaging techniques, among which functional magnetic resonance imaging (fMRI) is the best known. These techniques are not based on direct observations of electric impulses from activated neurons, but on one of their consequences. Indeed, this stimulation triggers physiological modifications in the activated cerebral region, changes that become visible by imaging. Until now, it was believed that these differences were only due to modifications of the blood influx towards the cells. By using intrinsic optical signals (IOS) imaging, researchers have now demonstrated that, contrary to what was thought, another physiological variation is involved: the activated neurons swell due to the massive entry of water.
  • First comprehensive analysis of the woolly mammoth genome completed
    The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt Arctic life, including skin and hair development, insulin signaling, fat biology, and even traits such as small ears and short tails. A mammoth gene for temperature sensation was resurrected in the lab as a functional test.
  • New technology using silver may hold key to electronics advances
    Engineers have invented a way to fabricate silver, a highly conductive metal, for printed electronics that are produced at room temperature. There may be broad applications in microelectronics, sensors, energy devices, low emissivity coatings and even transparent displays.

    Physicists have found a way of using everyday technology found in kitchen microwaves and mobile telephones to bring quantum technology closer.
  • Working out in artificial gravity
    Engineers have built a compact human centrifuge with an exercise component: a cycle ergometer that a person can pedal as the centrifuge spins. The centrifuge was sized to just fit inside a module of the ISS. After testing the setup on healthy participants, the team found the combination of exercise and artificial gravity could significantly lessen the effects of extended weightlessness in space -- more so than exercise alone.
  • How our sense of smell evolved, including in early humans
    A group of scientists has studied how our sense of smell has evolved, and has even reconstructed how a long-extinct human relative would have been able to smell.
  • Dark matter map begins to reveal the Universe's early history
    Researchers have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in Hawai'i.
  • Scientists warn of species loss due to human-made landscapes
    Researchers say farmland is a poor substitute for natural areas but simple improvements could make a difference to biodiversity conservation.
  • Review indicates where cardio benefits of exercise may lie
    A systematic review of 160 clinical trials of the cardiometabolic benefits of exercise shows which health indicators improve most with physical activity and for whom. For example, some of the benefits are greater for men, people under 50 and among those battling type 2 diabetes or other cardiovascular conditions.
  • Digesting bread and pasta can release biologically active molecules
    Biologically active molecules released by digesting bread and pasta can survive digestion and potentially pass through the gut lining, suggests new research. The study reveals the molecules released when real samples of bread and pasta are digested, providing new information for research into gluten sensitivity.
  • Bad sleep habits linked to higher self-control risks
    Poor sleep habits can have a negative effect on self-control, which presents risks to individuals' personal and professional lives, according to researchers. Psychologists concluded a sleep-deprived individual is at increased risk for succumbing to impulsive desires, inattentiveness and questionable decision-making.
