Volcanic fertilization of the oceans drove severe mass extinction

Science Daily - 02/12/2021
Scientists have discovered that two intense spells of volcanic activity triggered a period of global cooling and falling oxygen levels in the oceans, which caused one of the most severe mass extinctions in Earth history - the 'Late Ordovician Mass Extinction', 450 million years ago.

How digital and molecular data can be integrated and used to improve health

Science Daily - 02/12/2021
Analysing molecular characteristics and their variation during lifestyle changes, by combining digital tools, classical laboratory tests and new biomolecular measurements, could enable individualised prevention of disease. The researchers show what a proactive healthcare model could comprise and how it could help in maintaining good health.

A pair of gold flakes creates a self-assembled resonator

Science Daily - 02/12/2021
For exploring materials right down to the nano-level, researchers often need to construct a complex structure to house the materials -- a time-consuming and complicated process. But imagine if there was a way the structure could simply build itself?

Climate modeling confirms historical records showing rise in hurricane activity

Science Daily - 02/12/2021
Scientists have now used climate modeling, rather than storm records, to reconstruct the history of hurricanes and tropical cyclones around the world. The study finds that North Atlantic hurricanes have indeed increased in frequency over the last 150 years, similar to what historical records have shown.

Mouse study suggests manipulation of certain nerve cells can help regenerate lost heart muscle

Science Daily - 02/12/2021
Human heart muscle cells cease to multiply after birth, making any heart injury later in life a permanent one, reducing function and leading to heart failure. Now, however, researchers say they have new evidence from mouse experiments that manipulating certain nerve cells or the genes that control them might trigger the formation of new heart muscle cells and restore heart function after heart attacks and other cardiac disorders.

Cannabis impacts sperm counts, motility in two generations of mice

Science Daily - 02/12/2021
An intense but short-term exposure to cannabis vapor lowered sperm counts and slowed sperm movement, or motility, not only in the directly exposed male mice but also in their sons, according to a new study. The findings build on other human and animal research, showing that cannabis can impede male reproductive function. The current study uses more controlled circumstances than human studies, which often have to rely on surveys, and is the first known reproductive study to use vaporized whole cannabis in mice, which is the more common form humans use. Previous animal studies use other administration methods such as injections of tetrahydrocannabinol (THC), the main psychoactive component of cannabis.

Septic system waste pervasive throughout Florida’s Indian River lagoon

Science Daily - 02/12/2021
There are more than 300,000 septic systems permitted in six counties adjacent to the 156-mile-long Indian River Lagoon (IRL) in Florida. Researchers assessed water quality and measured stable nitrogen isotopes in groundwater, surface water, and macrophyte tissue to identify nitrogen sources impacting the lagoon. Sucralose, an artificial sweetener that is not completely broken down by septic systems or wastewater treatment plants, was used as a human wastewater tracer, and fecal indicator bacteria density was used as an indicator of wastewater pollution. Results showed that nitrogen enrichment of all sub-drainage basins in this study supports that even 'properly functioning' septic systems contribute nitrogen to surficial (shallow) groundwater.

Improving perceptions of emerging technologies can help ease strain on health-care systems

Science Daily - 02/12/2021
More attention must be paid to improving perceptions of emerging technologies like AI-powered symptom checkers, which could ease the strain on health-care systems, according to a recent study.

Ocean plastic is creating new communities of life on the high seas

Science Daily - 02/12/2021
Coastal plants and animals have found a new way to survive in the open ocean -- by colonizing plastic pollution. A new commentary reports coastal species growing on trash hundreds of miles out to sea in the North Pacific Subtropical Gyre, more commonly known as the 'Great Pacific Garbage Patch.'

Which role models are best for STEM? Researchers offer recommendations in new analysis

Science Daily - 02/12/2021
An analysis of the effect role models have on students' motivation in studying STEM subjects points to new ways to deploy these leaders in order to encourage learning across different populations.

Novel immune cell population may trigger inflammation in multiple sclerosis and other brain disorders

Science Daily - 02/12/2021
A group of immune cells that normally protect against inflammation in the gastrointestinal tract may have the opposite effect in multiple sclerosis (MS) and other brain inflammation-related conditions, according to a new study. The results suggest that countering the activity of these cells could be a new therapeutic approach for such conditions.
