Why people didn’t social distance
The Stanford-led study found the most common reasons people did not follow social distancing recommendations were work requirements, mental and physical health concerns and beliefs that other precautions were enough. Maintaining social distance has been crucial in slowing the spread of novel coronavirus infections (COVID-19), yet some people did not follow early recommendations to limit physical contact with others.

Spider venom key to pain relief without side-effects
Molecules in tarantula venom could be used as an alternative to opioid pain killers for people seeking chronic pain relief. University of Queensland researchers have designed a novel tarantula venom mini-protein that can potentially relieve severe pain without addiction. Dr Christina Schroeder from UQ's Institute for Molecular Bioscience said the current opioid crisis around the world meant urgent alternatives to morphine and morphine-like drugs, such as fentanyl and oxycodone, were desperately needed.

Molecular and isotopic evidence for milk, meat, and plants in prehistoric eastern African herder food systems
Molecular and isotopic evidence for milk, meat, and plants in prehistoric eastern African herder food systems
The development of pastoralism is known to have transformed human diets and societies in grasslands worldwide. Cattle-herding has been (and still is) the dominant way of life across the vast East African grasslands for thousands of years. This is indicated by numerous large and highly fragmentary animal bone assemblages found at archaeological sites across the region, which demonstrate the importance of cattle, sheep and goat to these ancient people.

Risk of viruses emerging in humans may not depend on their animal host
The likelihood of emerging viruses spreading to humans from animals may not depend on the specific animal reservoir of the original virus. Like the current pandemic caused by the coronavirus SARS-CoV-2, which is thought to have originated in bats, most emerging infectious diseases are zoonotic viruses - diseases that spread from animals to infect humans.

Supernova that outshines all others
A supernova at least twice as bright and energetic, and likely much more massive than any yet recorded has been identified by an international team of astronomers, led by the University of Birmingham. The team, which included experts from Harvard , Northwestern University and Ohio University , believe the supernova, dubbed SN2016aps, could be an example of an extremely rare ‘pulsational pair-instability' supernova, possibly formed from two massive stars that merged before the explosion.

Yale test of immunotherapy drug for advanced lung cancer shows promise
Lung cancer spreads to the brain in about one-quarter of patients with an advanced form of the disease. To date, radiation has been the only treatment option, but it comes with toxic side effects. Researchers at Yale Cancer Center (YCC) have found that use of the checkpoint inhibitor pembrolizumab in place of radiation can extend life with very few side effects in this patient population.

Milk allergy guidelines may cause overdiagnosis in babies and children
Current medical guidelines for diagnosing cow's milk allergy in babies and young children may be linked to overdiagnosis of the condition. This is the finding of a new analysis from Imperial College London and Sechenov University in Moscow. Many infants who are labelled as having milk allergy don't have the condition Dr Robert Boyle Study author In the paper, a review published in the journal JAMA Pediatrics , the team found that around 1 per cent of children have cow's milk allergy, but up to 14 per cent of families believe their child to have the condition.

Provides new insights into menopause and weight gain
Can women in menopause get the benefits of hormone replacement therapy without the risks' A new UCLA study conducted with mice points in that direction, but additional research is necessary. Women commonly experience hot flashes and weight gain, among other changes, during and after menopause. Hormone therapy, which gives women additional estrogen, can help alleviate some of these symptoms, but it has been linked to a higher risk of heart disease and breast cancer.

Brightest Supernova Ever Seen
Harvard & Smithsonian today announced the discovery and study of the brightest, most energetic, and likely most massive supernova ever identified. SN2016aps is believed to be an example of a "pulsational pair instability" supernova, and may have formed as the result of the merging of two massive stars prior to the explosion.

Mandated TB vaccination predicts flattened curves for COVID-19 spread
If the United States had mandatory tuberculosis vaccination in place several decades prior, the total number of coronavirus-related deaths might not have reached triple digits by late March. In fact, according to a new University of Michigan report, the U.S. would have suffered an estimated 94 deaths, which would have been only 4% of the actual death toll of 2,467 in this country on March 29.

PulseCam peeks below skin to map blood flow
PulseCam peeks below skin to map blood flow
Rice U. tech could let doctors monitor blood perfusion in real time Rice University engineers have found a way to use a video camera to peek below the skin and make high-resolution maps that show doctors and nurses exactly how much blood is reaching the capillaries. PulseCam uses a patented process to combine information from video recordings and a pulse oximeter to create high-resolution blood perfusion maps.

Researchers achieve remote control of hormone release
Using magnetic nanoparticles, scientists stimulate the adrenal gland in rodents to control release of hormones linked to stress. Abnormal levels of stress hormones such as adrenaline and cortisol are linked to a variety of mental health disorders, including depression and posttraumatic stress disorder (PTSD).

First sighting of mysterious Majorana fermion on a common metal
First sighting of mysterious Majorana fermion on a common metal
Physicists at MIT and elsewhere have observed evidence of Majorana fermions - particles that are theorized to also be their own antiparticle - on the surface of a common metal: gold. This is the first sighting of Majorana fermions on a platform that can potentially be scaled up. The results, published in the Proceedings of the National Academy of Sciences , are a major step toward isolating the particles as stable, error-proof qubits for quantum computing.

How artificial intelligence can help to design new drugs
How artificial intelligence can help to design new drugs
Traditional methods for predicting interactions between proteins and other molecules rely on complex supercomputer simulations. Instead, a group of researchers from EPFL and USI developed a new artificial intelligence system that analyzes the 3D structure of protein surfaces. The new methodáMaSIF (Molecular Surface Interaction Fingerprinting) is a collaboration between the EPFL Protein Design & Immunoengineering lab (headed by Prof. Bruno Correia) and the group of Michael Bronstein , professor at USI and Imperial College of London, and head of research in Graph Learning at Twitter.

Risk aversion as a survival strategy in ants
Risk aversion as a survival strategy in ants
Ants are excellent navigators and always find their way back to the nest. But how do they react when an obstacle or a predator blocks their path? An international team including Antoine Wystrach, a CNRS researcher at the Research Centre on Animal Cognition (CNRS/UniversitÚ Tou-louse III - Paul Sabatier), has shown that ants are capable of changing their familiar route to avoid traps thanks to an aversive learning mechanism: by associating visual cues with negative experiences, they can memorise potentially dangerous routes.
