Slimming down a colossal fossil whale

A 30 million year-old fossil whale may not be the heaviest animal of all time after all, according to a new analysis by paleontologists. The new analysis puts Perucetus colossus back in the same weight range as modern whales and smaller than the largest blue whales ever recorded.

Lockdowns had an impact on gut microbes and allergies in newborns, new research reveals

Lockdowns imposed during the COVID-19 pandemic had an impact on the gut microbiome development of babies born during these periods according to new research. Our gut microbiome, an ecosystem of microbes that live in our digestive tract, plays an essential role in human health. The study reveals significant differences in the microbiome development of babies born during lockdown periods when...


A safer treatment path for high-risk children to overcome food allergies

New research reveals a safe path to overcoming food allergies for older children and others who can't risk consuming allergens orally to build up their resistance. It's called sublingual immunotherapy (SLIT), and it involves placing smaller amounts of food allergens under the tongue. A study has found SLIT to be as safe and effective for high-risk older children and adolescents as oral...

In fight against brain pathogens, the eyes have it

The eyes have been called the window to the brain. It turns out they also serve as an immunological barrier that protects the organ from pathogens and even tumors, researchers have found. In a new study, researchers showed that vaccines injected into the eyes of mice can help disable the herpes virus, a major cause of brain encephalitis. To their surprise, the vaccine activates an immune response...

The West is best to spot UFOs

Researchers identified environmental factors that explain why reports of Unidentified Anomalous Phenomena (UAP) are more common in certain regions of the country. Most sightings occur in the American West where proximity to public lands, dark skies and military installations afford more opportunities to see strange objects in the air. Understanding the environmental context of these sightings will...

Climate change shrinking fish

Fish weight in the western North Pacific Ocean dipped in the 2010s due to warmer water limiting food supplies, according to a new study. Researchers analyzed the individual weight and overall biomass of 13 species of fish. In the 1980s and 2010s, the fish were lighter. They attributed the first period of weight loss to greater numbers of Japanese sardine, which increased competition with other...

Want fewer microplastics in your tap water? Try boiling it first

Nano- and microplastics are seemingly everywhere -- water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and...


Teens benefit from 'forest bathing' -- even in cities

Youth mental health in urban environments is significantly better when more nature is incorporated into city design. A new study suggests that forest bathing, the simple method of being calm and quiet amongst the trees, observing nature around you while breathing deeply, can help youth de-stress and boost health and well-being.

Addressing societal concerns of genetic determinism of human behavior by linking environmental influences and genetic research

In a new perspective article, researchers underscore the importance of integrating environmental effects into genetic research. The authors discuss how failure to do so can perpetuate deterministic thinking in genetics, as historically observed in the justification of eugenics movements and, more recently, in cases of racially motivated violence.

Maths: Smart learning software helps children during lockdowns -- and beyond

Intelligent tutoring systems for math problems helped pupils remain or even increase their performance during the coronavirus pandemic, according to a new study. Researchers analyzed data from five million exercises done by around 2,700 pupils in Germany over a period of five years. The study found that particularly lower-performing children benefit if they use the software regularly.
