Immune system, not COVID virus, may pose greatest risk to pregnant women

Scientists investigated whether the COVID-19 virus could be affecting placental tissue of infected expectant mothers. Their analysis found that while evidence of the virus in the placenta is rare, the placenta in infected mothers tended to exhibit a much higher level of immune system activity than those of non-infected pregnant women, they report.

Using exoplanets as dark matter detectors

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

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.

Among COVID-19 survivors, an increased risk of death, serious illness

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...

The future looks bright for infinitely recyclable plastic

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.

Common antibiotic effective in healing coral disease lesions

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...

More belly weight increases danger of heart disease even if BMI does not indicate obesity

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...

ALMA discovers rotating infant galaxy with help of natural cosmic telescope

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...

Higher mushroom consumption is associated with a lower risk of cancer

Higher mushroom consumption is associated with a lower risk of cancer, according to a new study. The systematic review and meta-analysis examined 17 cancer studies published from 1966 to 2020. Analyzing data from more than 19,500 cancer patients, researchers explored the relationship between mushroom consumption and cancer risk.
