Darkness is as essential to our biological welfare, to our internal clockwork, as light itself.

David Dominoni, of Glasgow university, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clocks, leading to them being wide awake when they should be asleep.

For example, the moment you get on the airplane, start adjusting your biological clock to the destination's time.

Light is a powerful biological force, and on many species it acts as a magnet.

One important biological factor that helps women live longer is the difference in hormones between men and women.

One reason for this is biological.

In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.

Our food intake is determined by our biological needs

Behavioral genetics has made important contributions to the biological revolution, providing information about the extent to which biology influences mind, brain and behavior.

On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more.

Their invention is a small biological circuit they call E-Kaia.

While we argue phasing out racial terminology ( ' , 术语 ) in the biological sciences, we also acknowledge that using race as a political or social category to study racism, although filled with lots of challenges, remains necessary given our need to understand how structural inequities and discrimination produce health disparities ( ' , 差异 ) between groups, Yudell said.

Today, the mainstream belief among scientists is that race is a social construct without biological meaning.

The researchers also acknowledged that there are a few areas where race as a construct might still be useful in scientific research: as a political and social, but not biological, variable.

E.B.Du Bois was concerned that race was being used as a biological explanation for what he understood to be social and cultural differences between different populations of people.

There is a biological rhythm for learning, though it affects different people in different ways.

today, the mainstream belief among scientists is that race is a social construct without biological meaning.

Coinciding with the groundbreaking theory of biological evolution proposed by British naturalist Charles Darwin in the 1860s, British social philosopher Herbert Spencer put forward his own theory of biological and cultural evolution.

Join the Club is filled with too much irrelevant detail and not enough exploration of the social and biological factors that make peer pressure so powerful.

Biological factors behind eye contact are being investigated.
