  • How stress can curb the desire to eat in an animal model
    Eating disorder researchers have discovered a neurocircuit in mice that, when activated, increased their stress levels while decreasing their desire to eat. Read more »
  • Physiological mechanisms leading to enterovirus opening revealed
    Enteroviruses are one of the most common human pathogens leading to high number of acute and chronic infections worldwide. The physiological events leading to successful enterovirus infection are still poorly understood. Researchers have found significant new information concerning the role of Albumin and ions in host cell vesicles that promote genome release and efficient infection. Read more »
  • Discovery of anti-opioid pathway offers new route to designing safer pain medications
    A team has discovered a biological system that manages cells' response to opioid drug exposure. The unexpected discovery offers new ideas for improving the safety of the one of the most effective, and most abused, group of pain medications. Read more »
  • Children with mild asthma can use inhalers as needed, study suggests
    A new study supports evidence that children with mild asthma can effectively manage the condition by using their two inhalers -- one a steroid and the other a bronchodilator -- when symptoms occur. This is in contrast to the traditional method of using the steroid daily, regardless of symptoms, and the bronchodilator when symptoms occur. The as-needed use of both inhalers is just as effective for mild asthma as the traditional protocol, according to the investigators. Read more »
  • Researchers refine guidelines for pediatric brain injuries
    There are no guidelines on whether a noninvasive method of measuring carbon dioxide from patients' exhalations, known as end-tidal capnography, is as effective as drawing blood through a child's artery. This study found that measuring the carbon dioxide level through an artery is still the most accurate diagnostic for pediatric brain trauma. Read more »
  • Cannabis-related poison control calls for Massachusetts kids doubled after medical pot legalized
    After medical marijuana became legal in Massachusetts, cannabis-related poison control calls involving the commonwealth's children and teenagers doubled, according to a public health investigation. Read more »
  • Neuronal mechanism that is central to human free recall identified
    Recently Weizmann Institute scientists succeeded in recording these rapid bursts of activity -- called 'hippocampal ripples' -- in the human brain, and they were able to demonstrate their importance as a neuronal mechanism underlying the engraving of new memories and their subsequent recall.

  • Researcher decodes the brain to help patients with mental illnesses
    Approximately 1 in 5 adults in the United States experience mental illness in a given year. Severe mental illnesses cause the brain to have trouble dealing with cognitively effortful states, like focusing attention over long periods of time, discriminating between two things that are difficult to tell apart, and responding quickly to information that is coming in fast.

  • How E. coli knows how to cause the worst possible infection
    The discovery could one day let doctors prevent the infection by allowing E. coli to pass harmlessly through the body. Read more »
  • Wireless sensors that stick to the skin to track our health
    Engineers have developed experimental stickers that pick up physiological signals emanating from the skin, then wirelessly beam these health readings to a receiver clipped onto clothing. It's all part of a system called BodyNet. Read more »

  • July 2019 was hottest month on record for the planetJuly 2019 was hottest month on record for the planet
    Much of the planet sweltered in unprecedented heat in July, as temperatures soared to new heights in the hottest month ever recorded. The record warmth also shrank Arctic and Antarctic sea ice to historic lows. Read more »
  • Moon glows brighter than sun in images from NASA's FermiMoon glows brighter than sun in images from NASA's Fermi
    If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade. Read more »
  • Young Jupiter was smacked head-on by massive newborn planetYoung Jupiter was smacked head-on by massive newborn planet
    A colossal, head-on collision between Jupiter and a still-forming planet in the early solar system, about 4.5 billion years ago, could explain surprising readings from NASA's Juno spacecraft, according to a new study. Read more »
  • New study shows how autism can be measured through a non-verbal markerNew study shows how autism can be measured through a non-verbal marker
    Researchers have identified a non-verbal, neural marker of autism. This marker shows that individuals with autism are slower to dampen neural activity in response to visual signals in the brain. This first-of-its kind marker was found to be independent of intelligence and offers an objective way to potentially diagnose autism… Read more »
  • Brain molecule identified as key in anxiety modelBrain molecule identified as key in anxiety model
    Boosting a single molecule in the brain can change 'dispositional anxiety,' the tendency to perceive many situations as threatening, in nonhuman primates, researchers have found. The molecule, neurotrophin-3, stimulates neurons to grow and make new connections. Read more »
  • Microplastic drifting down with the snowMicroplastic drifting down with the snow
    Over the past several years, microplastic particles have repeatedly been detected in sea-water, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow -- and even in such remote regions as the Arctic and… Read more »
  • How many Earth-like planets are around sun-like stars?How many Earth-like planets are around sun-like stars?
    A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Read more »
  • Schrödinger's cat with 20 qubitsSchrödinger's cat with 20 qubits
    Dead or alive, left-spinning or right-spinning -- in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, together with experts from Forschungszentrum Jülich, have now succeeded in transforming 20 entangled quantum bits into such a… Read more »
