Lithium treats intellectual defects in mouse model of Bardet-Biedl Syndrome
Thu, 22 Apr 2021 18:19:07 EDT
Mice with symptoms that mimic Bardet-Biedl Syndrome (BBS) have difficulty with learning and generating new neurons in the hippocampus. However, according to a new study, these mental defects can be successfully treated with lithium.
Ancient Indigenous forest gardens promote a healthy ecosystem
Thu, 22 Apr 2021 18:19:02 EDT
A new study by historical ecologists finds that Indigenous-managed forests -- cared for as 'forest gardens' -- contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators.

Thu, 22 Apr 2021 18:18:56 EDT
In a worldwide study of 2,100 pregnant women, those who contracted COVID-19 during pregnancy were 20 times more likely to die than those who did not contract the virus.
Mars has right ingredients for present-day microbial life beneath its surface, study finds
Thu, 22 Apr 2021 15:04:13 EDT
New research suggests that rocks in the Martian crust could produce the same kind of chemical energy that supports microbial life deep beneath Earth's surface.
Ground and satellite observations map building damage after Beirut explosion
Thu, 22 Apr 2021 12:36:49 EDT
Days after the 4 August 2020 massive explosion at the port of Beirut in Lebanon, researchers were on the ground mapping the impacts of the explosion in the port and surrounding city. The goal was to document and preserve data on structural and fa├žade damage before rebuilding.
The science of spin: Asteroseismologists confirm older stars rotate faster than expected
Thu, 22 Apr 2021 12:36:46 EDT
Stars spin faster than expected as they age according to a new study which uses asteroseismology to shed new light on this emerging theory.
Study of 'breakthrough' cases suggests COVID testing may be here to stay
Thu, 22 Apr 2021 12:36:31 EDT
Two new cases helped scientists confirm what many have come to suspect: that people can get infected by SARS-CoV-2 variants even after successful vaccination. The findings suggest continued testing may be needed to prevent future outbreaks in a post-vaccine world.
How we know whether and when to pay attention
Thu, 22 Apr 2021 12:36:28 EDT
International team of researchers identifies cognitive computations underlying human predictive behavior.
Using exoplanets as dark matter detectors
Thu, 22 Apr 2021 12:36:20 EDT
In the continuing search for dark matter in our universe, scientists believe they have found a unique and powerful detector: exoplanets. Astrophysicists suggest dark matter could be detected by measuring the effect it has on the temperature of exoplanets, which are planets outside our solar system.
Fighting harmful bacteria with nanoparticles
Thu, 22 Apr 2021 12:36:16 EDT
Multi-resistant pathogens are a serious and increasing problem in today's medicine. Where antibiotics are ineffective, these bacteria can cause life-threatening infections. Researchers are currently developing nanoparticles that can be used to detect and kill multi-resistant pathogens that hide inside our body cells. The team published the study in the current issue of the journal Nanoscale.
California's wildfire season has lengthened, and its peak is now earlier in the year
Thu, 22 Apr 2021 12:36:11 EDT
Researchers have analyzed CALFIRE wildfire statistics from 2000 to 2019, comparing them with data from 1920 to 1999, to learn that the annual burn season has lengthened in the past two decades and that the yearly peak has shifted from August to July.
Among COVID-19 survivors, an increased risk of death, serious illness
Thu, 22 Apr 2021 12:36:03 EDT
Researchers showed that COVID-19 survivors -- including those not sick enough to be hospitalized -- have an increased risk of death in the six months following diagnosis with the virus. They also have catalogued the numerous diseases associated with COVID-19, providing a big-picture overview of the long-term complications of COVID-19 and revealing the massive burden this disease is likely to place on the world's population in the coming years.
Mars' changing habitability recorded by ancient dune fields in Gale crater
Thu, 22 Apr 2021 10:29:01 EDT
An international team has found evidence of ancient dunes on Mars that could help explain ancient surface conditions.
The future looks bright for infinitely recyclable plastic
Thu, 22 Apr 2021 10:28:51 EDT
Plastics are ubiquitous, but they're not practical. Less than 10% are recycled, and the other approximately 8 billion tons are creating a pollution crisis. Researchers are determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.
Artificial intelligence model predicts which key of the immune system opens the locks of coronavirus
Thu, 22 Apr 2021 09:39:43 EDT
A new artificial intelligence (AI) method is helping researchers link immune cells to their targets and, for example, uncouple which white blood cells recognize SARS-CoV-2. The tool has broad applications in understanding the function of the immune system in infections, autoimmune disorders, and cancer.
Faster air exchange in buildings not always beneficial for coronavirus levels
Thu, 22 Apr 2021 09:38:49 EDT
Vigorous and rapid air exchanges might not always be a good thing when it comes to levels of coronavirus particles in a multiroom building, according to a new modeling study. Particle levels can spike in downstream rooms shortly after rapid ventilation.
Common antibiotic effective in healing coral disease lesions
Thu, 22 Apr 2021 09:38:47 EDT
An antibiotic used to treat bacterial infections in humans is showing promise in treating stony coral, found throughout the tropical western Atlantic, including several areas currently affected by stony coral tissue loss disease. Preserving M. cavernosa colonies is important due to its high abundance and role as a dominant reef builder in the northern section of Florida's Coral Reef. Results show that the Base 2B plus amoxicillin treatment had a 95 percent success rate at healing individual disease lesions.
More belly weight increases danger of heart disease even if BMI does not indicate obesity
Thu, 22 Apr 2021 09:38:42 EDT
Research on how obesity impacts the diagnosis, management and outcomes of heart and blood vessel disease, heart failure and arrhythmias is summarized in a new statement. Waist circumference, an indicator of abdominal obesity, should be regularly measured as it is a potential warning sign of increased cardiovascular disease risk. Interventions that lead to weight loss improve risk factors yet may not always lead to improvement in coronary artery disease outcomes.
ALMA discovers rotating infant galaxy with help of natural cosmic telescope
Thu, 22 Apr 2021 09:38:39 EDT
Using ALMA, astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark 'normal galaxies' in the early Universe, which greatly advances our understanding of the initial phase of galaxy evolution.
Know your ally: Cooperative male dolphins can tell who's on their team
Thu, 22 Apr 2021 09:38:35 EDT
When it comes to friendships and rivalries, male dolphins know who the good team players are. New findings reveal that male dolphins form a social concept of team membership based on cooperative investment in the team.
