Watching bacteria and viruses duke it out, evolving to outwit each other.
UC San Diego
A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
We are told driverless cars will be much safer, because human error causes more than 90% of crashes.
Human-operated cars affect health in three main ways, all negatively. How might driverless cars be healthier?
Having to own multiple cars comes at a cost to the finances and health of residents in the sprawling outer suburbs.
One of the most effective ways to reduce health inequalities across Australia is to design neighbourhoods that free residents from having to rely on cars for transport.

Dropping old, bad habits is hard, but starting new, good ones may not be so difficult. Or so a recent study suggests. Read how a simple sign at an airport made a difference.
Computer training can decrease children’s biases.
Racial bias is associated with dehumanizing social groups different from your own. Psychologists trained kids to differentiate individuals of another race – with lasting effects on their biases.
Staying physically active can play a big part in ageing well – and a well-designed neighbourhood helps with that.
Our ageing population presents several social and economic challenges, particularly for the health sector. Physical activity can tackle many of these.

Congress has an opportunity to build on DACA's success. An immigration expert explains how.
It’s actually a big developmental milestone.
In a new study, psychologists observed young children in real time figuring out how not to tell the truth.

The wealthy evade taxes and are less likely to donate to charity, but does this mean they're more selfish than everyone else? New research suggests not.
How you package the information matters.

Are we in a race against climate change? Or is it a war? How does thinking of the past or the future affect your support for the science? Researchers are learning how metaphors and context matter.

We need international agreement on a set of Earth's 'vital signs' and how to measure them.
A wall to nowhere?

President Trump signed an executive order to get construction started and ask Congress to pay up front, but good luck getting Mexico to foot the bill.

This isn't the first time the US has banned people based on nationality. History shows these exclusions have put our national security at risk and caused rifts with foreign allies.
Yeah, I’m not hearing that.

Quirks of human psychology can pose problems for science communicators trying to cover controversial topics. Recognizing what cognitive science knows about how we deal with new information could help.

We have a reliable and easy-to-use test to measure blood alcohol concentration. But right now we don't have a fast, reliable test to gauge whether someone is too doped up to drive.

As the vaquita porpoise heads towards extinction, new management measures in Mexico still may have missed the point -- affecting not one but two critically endangered marine species.
Cell nucleus with RNA.
Aging and cancer appear to be closely linked, as over time, cells accumulate hits in their DNA code. But now research has turned to the role of RNA. Is RNA the key to a longer life?

Could this new technology do for the microscopic marine world what the first telescopes did for the heavens above?
Imagined view from the surface of one of the newly discovered planets, with ultracool dwarf star TRAPPIST-1 in the background.
We don't need to look for Earth-like planets exclusively around Sun-like stars. Tiny, dim TRAPPIST-1 has only 11 percent the diameter of the Sun and is much redder.
