Reactivation of Steamboat Geyser
Researchers examine why the world’s tallest geyser reactivated. Steamboat Geyser in Yellowstone National Park’s Norris Geyser Basin erupted on March 15, 2018, after more than 3 years of dormancy. To better understand why the geyser reactivated, Mara Reed, Michael Manga,…
Moving after natural disasters is linked to long-term health problems
Individual and group relocation after the 2011 earthquake and tsunami in Japan was associated with different long-term health issues, a study finds. Large-scale natural disasters can lead to residential displacement, but relatively little is known about the long-term health consequences.…
Human expansion changed climatic niches mammals occupy
A recent fossil analysis covering 11,700 years finds that many US mammal species are living in different climates than they did prior to human expansion. The growth of cities and agricultural areas contributes to range loss and habitat fragmentation. Silvia…
COVID-19 and climate change concerns in the United Kingdom
According to a representative longitudinal survey of more than 1,800 adults in the United Kingdom, conducted in April 2019 and June 2020, belief in the reality and severity of anthropogenic climate change has not diminished during the COVID-19 pandemic and…
Neuroscientists seek Parkinson’s, addiction insights by tracking gene expression
Two MIT neuroscientists have received grants from the G. Harold and Leila Y. Mathers Foundation to screen for genes that could help brain cells withstand Parkinson’s disease and to map how gene expression changes in the brain in response to…
Alpha-ray missile therapy: tumor cells attacked from intracellular region
Researchers at Osaka University have developed a technique of attacking cancer cells with lethal alpha rays from within by using a nutrient transporter to deliver radionuclides into malignant tumors

Scientists crunch data to “screen” candidates for drug repurposing
Research shows a few beneficial organisms could play key role in treating type 2 diabetes
PORTLAND, Ore. – Researchers at Oregon State University have found that a few organisms in the gut microbiome play a key role in type 2 diabetes, opening the door to possible probiotic treatments for a serious metabolic disease affecting roughly…
Self-control and midlife aging
Researchers examine how childhood self-control influences midlife aging. The relationship between self-control and aging is unclear. To determine whether self-control in childhood can predict the course of aging, Leah Richmond-Rakerd and colleagues followed a cohort of 1,037 individuals born in…
Single-cell RNA sequencing of immune cells involved in asthma attacks
A study provides insight into the immune response involved in asthma exacerbation. Asthma exacerbations, or asthma attacks, are the major cause of asthma-related hospitalizations and the primary source of asthma-related healthcare costs. Asthma exacerbations resist standard glucocorticoid-based therapy and are…
Convex to concave: More metasurface moiré results in wide-range lens
The odd, wavy pattern that results from viewing certain phone or computer screens through polarized glasses has led researchers to take a step toward thinner, lighter-weight lenses. Called moiré, the pattern is made by laying one material with opaque and…
Study of 50,000 people finds brown fat may protect against numerous chronic diseases
Brown fat is that magical tissue that you would want more of. Unlike white fat, which stores calories, brown fat burns energy and scientists hope it may hold the key to new obesity treatments. But it has long been unclear…

Traditional stereotypes about masculinity may help explain support for Trump
UNIVERSITY PARK, Pa. — American politicians have long been expected to uphold a certain veneer: powerful, influential and never vulnerable. New Penn State research has found that these idealized forms of masculinity may also help explain support for Donald Trump…
Views of masculinity and support for Donald Trump
Seven studies involving 2,007 people find that, in both the 2016 and 2020 US presidential elections, men’s and women’s endorsement of hegemonic masculinity–which reinforces the power, status, and toughness of dominant men over women and marginalized men–predicted voting for and…
The impact of climate shock on a fishing industry
Researchers report fishing industry responses to the 2015-16 Dungeness crab fishery closures to show how network analysis of pre-shock harvesting behavior can predict the extent to which resource use patterns change during a climate shock. The 2014-2016 North Pacific marine…

Announcement of new peer-reviewed journal for neurosurgeons and medical personnel.
Clinical criteria for diagnosing autism inadequate for people with genetic conditions
More than half of individuals with one of four genetic conditions had significant autistic symptoms, despite not qualifying for formal diagnosis
Nanoparticle drug-delivery system developed to treat brain disorders
Use of the delivery system in mouse models results in unprecedented siRNA penetration across the intact blood brain barrier
Putty-like composites of gallium metal with potential for real-world application
Excellent intrinsic properties of these composites will allow them to have a wide range of use, from shielding the grid from coronal mass ejection events to more effective thermal pastes
Comb of a lifetime: a new method for fluorescence microscopy
Scientists develop a fluorescence “lifetime” microscopy technique that uses frequency combs and no mechanical parts to observe dynamic biological phenomena
