We know the left and right side of our brain are specialized for cognitive abilities like language (left hemisphere) and the right hand. That functional lateralization is reflected by morphological asymmetry too. The left and right hemispheres differ subtly in brain anatomy, distribution of nerve cells, connectivity and even neurochemistry.

It can be seen on endocasts. Most humans have a combination of a more projecting left occipital lobe (located in the back of the brain) with a more projecting right frontal lobe.

Despite what you've heard, birds of a feather often don't flock together. In the real world, multiple bird species are often flying and feeding together. In the Amazon, 50 species may travel as a unit.

But are birds in these mixed flocks cooperating with one another or competing?

A new study suggests both. Just like a K-pop band such as BTS, Blackpink, or Red Velvet.

In a world of New York Times best-selling diet books and epidemiological claims about food and chemicals - even that if your mother used cosmetics it may have made you fat - it can be difficult for the public to know what to trust.

It won't be intermittent fasting, juice cleanses, or 10,000 steps, it will always be the calories. Energy balance matters, no matter how many times Center for Science in the Public Interest claims it's conspiracy to claim calories are why we gain weight.

After the 2020 census, it is expected that California will lose a seat in Congress and Texas will gain it. Texans tout greater personal freedom and lower taxes but a new study says it may be water.

California is mostly desert and gets the bulk of its water from other states. After another drought a few years ago the pubic demanded new water infrastructure, noting that California hasn't undertaken a major program since the 1960s while the population is over 100 percent greater. Housing costs are high because new construction can't take place without a water contract, forcing people to stay in coastal cities.

Smallpox was wiped out by using mathematical containment rings coupled with vaccines and it makes sense that one way to contain an infectious disease outbreak is to limit travel.

Unless travel bans are only bans for some people. In communist China, elites are still going on vacation, they are still traveling for business, they are still going to foreign colleges. The novel coronavirus in Wuhan, China, now known as COVID-19, has infected tens of thousands and killing hundreds while spreading to at least 24 other countries. That led many governments, including the United States, to restrict travel to and from China.

Mosquitoes rely on sense of smell to get what they need to survive. Females need blood to produce their eggs, so they find a host to bite and spots to lay eggs, while both males and females feed on nectar.

Their dominant source of food is nectar from flowers yet scientists know little about the scents that draw mosquitoes toward certain flowers, or repel them from others. Discovering this could help develop less toxic and better repellents, more effective traps, and lead to an understanding of how the mosquito brain responds to sensory information -- including the cues that, on occasion, lead a female mosquito to bite one of us.
