Patient with leg ulcers.
Dangerous open wounds known as cutaneous ulcers are common in people with diabetes and bedsores. Now scientists have figured out how to reprogram the cells inside these wounds to heal themselves.
You've heard the adage, you are what you eat. But a new study suggests that you are 'when' you eat may be more accurate. Restricting eating times can keep chronic diseases at bay and ward off obesity.
Nuevos records de suicidio indican que en México, varios años de baños de sangre sin precedentes han traumatizado a los residentes en las zonas donde existe mayor violencia.

New suicide data indicates that years of record bloodshed in Mexico have traumatized residents in places where the violence is most concentrated.
Ciudad Juárez, on the US-Mexico border, has suffered high levels of deadly violence for over a decade. New suicide data reveals the severe mental health impacts of living with chronic violence.
California’s San Onofre Nuclear Generating Station was shut down in 2013.
Commercial nuclear reactors provide roughly one-fifth of the electricity produced in the US. But they face grave threats to their continued operation.
What if it were a lot easier to install solar power?
Silicon is cheap and a good semiconductor, but it's bulky and rigid. Using organic polymers as semiconductors could yield solar panels with the physical characteristics of plastics.

Electric rideables are making life less comfortable and more dangerous for pedestrians. Here's how makers of rideables could help make cities safer for everybody.
Sitting can do more than give you a headache. It is linked to diabetes and obesity.
Researchers are learning even more about how a sedentary lifestyle is bad for our bodies. A recent study shows a link between sitting patterns and diabetes in older people.

In the largest citizen science experiment to date, 11,336 people sent poop samples to this San Diego lab so that microbiologists could figure out how the microbes in our guts make us healthy or sick.
Watching bacteria and viruses duke it out, evolving to outwit each other.

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.
