Exercise is healthy. That is common knowledge. But just how rigorous should that exercise be in order to really impact a person’s fitness level? And, if you sit all day at a desk, but still manage to get out and exercise, does that negate your six, seven, or eight hours of sedentary behavior? 

These were the sort of questions Matthew Nayor and his team at Boston University School of Medicine set out to answer in the largest study to date aimed at understanding the relationship between regular physical activity and a person’s physical fitness. 

The rapid development of effective mRNA vaccines for COVID-19 has led some observers to suggest that mRNA will push other types of vaccines out of the market completely in the near future. But is that desirable? Is it even possible?

The coconut is the sixth most cultivated fruit on earth and thanks to fads around things like coconut oil and water, demand continues to rise.

Growing products that rich people want is great for developing nations but they face challenges. Trees grow slowly and natural plagues Lethal Yellowing Disease put existing ones at risk. The answer may be what made bananas the staple they are now: cloning.

"Coconut plants do not form side shoots. They put all their energy into one shoot that has to grow as fast and as tall as possible. This makes it very difficult to clone and store the plants," said Bart Panis of KU Leuven.

Man's best friend learns to understand human emotions, and that can help them predict our behavior and informs their decision making.

Coronavirus may only have been identified as distinct from the common cold in the 1960s, and it may have only had two pandemics (SARS and MERS) in this century prior to COVID-19, but there is a reason it is called COVID-19 and not just COVID. There have been too many to know about.

Viruses evolve and adapt. New research shows Sarbecoviruses they have been hitting us with disease for over 20,000 years.

In 2019, astronomers spotted a snowball in space moving at over 110,000 miles per hour. They quickly realized they had never seen it before. It was not even from our solar system.

Now named Borisov, it was the first interstellar comet ever detected by humans. That doesn't make it rare.

A new computer estimate instead believes that in the Oort Cloud—a shell of debris in the farthest reaches of our solar system—interstellar objects outnumber objects belonging to our solar system.
