The causes and risks of the Amazon fires

Fires have been breaking out at an unusual pace in Brazil this year, causing global alarm over deforestation in the Amazon region. The world's largest rainforest is often called the "lungs of the earth." Here's a look at ...

Scientists explore outback as testbed for Mars

This week, scientists from NASA's upcoming Mars 2020 mission joined their counterparts from the joint European-Russian ExoMars mission in an expedition to the Australian Outback, one of the most remote, arid regions on the ...

The West is trading water for cash. The water is running out

When it comes to global warming's one-two punch of inundation and drought, the presence of too much water has had the most impact on U.S. agriculture this year, with farmers across the Midwest swamped by flooding throughout ...

Bioprinting complex living tissue in just a few seconds

Tissue engineers create artificial organs and tissues that can be used to develop and test new drugs, repair damaged tissue and even replace entire organs in the human body. However, current fabrication methods limit their ...

Breath! Respiring microbes generate more energy

How do cells generate and use energy? This question might seem simple, but the answer is far from simple. Furthermore, knowing how microbial cell factories consume energy and how proteins are allocated to do so is crucial ...

Scientists use a new method to track pollution from cooking

Cooking organic aerosol (COA) is one of the most important primary sources of pollution in urban environments. There is growing evidence that exposure to cooking oil fumes is linked to lung cancer. Currently, the most effective ...

Laser-produced uranium plasma evolves into more complex species

When energy is added to uranium under pressure, it creates a shock wave, and even a tiny sample will be vaporized like a small explosion. By using smaller, controlled explosions, physicists can test on a microscale in a safe ...
