Some domesticated plants ignore beneficial soil microbes

A review by biologists finds that plant domestication has often had a negative effect on plant microbiomes, making domesticated plants more dependent on fertilizer and other soil amendments than their wild relatives. To make crops more productive and sustainable, the authors recommend reintroduction of genes from the wild relatives of commercial crops that restore domesticated plants' ability to...

Second patient has been cured of HIV, study suggests

A study of the second HIV patient to undergo successful stem cell transplantation from donors with a HIV-resistant gene, finds that there was no active viral infection in the patient's blood 30 months after they stopped anti-retroviral therapy, according to a case report.

To make ultra-black materials that won't weigh things down, consider the butterfly

Some butterflies have ultra-black wings that rival the blackest materials made by humans, using wing scales that are only a fraction as thick. Using scanning electron microscopy and computer simulations to examine the microscopic structures on the wings of 10 species of ultra-black butterflies and four regular black or dark brown butterflies from Central and South America and Asia, researchers...

Community factors influence how long you'll live, study shows

While lifestyle choices and genetics go a long way toward predicting longevity, a new study shows that certain community characteristics also play important roles. American communities with more fast food restaurants, a larger share of extraction industry-based jobs, or higher population density have shorter life expectancies, according to researchers.

Scientists categorize neurons by the way the brain jiggles during a heartbeat

The brain jiggles when the heart beats, and now, researchers have found a way to use that motion to better study the differences between types of neurons. In a new study, researchers find that by analyzing the changes in the waveforms they record from neurons during a heartbeat, they can more accurately classify the different types of neurons in the human brain.

Children and teens worry about political issues

A new psychological study suggests that children and teens are worried about political issues, though it's unclear that children's and teens' worry is a cause for concern, or that it is interfering with their mental health functioning.

Mangrove conservation can pay for itself in flood protection

The natural coastal defenses provided by mangrove forests reduce annual flooding significantly in critical hotspots around the world. Without mangroves, flood damages would increase by more than $65 billion annually, and 15 million more people would be flooded, according to a new study.

Knowing more about a virus threat may not satisfy you

People who rate themselves as highly knowledgeable about a new infectious disease threat could also be more likely to believe they don't know enough, a new study suggests. In the case of this study, the infectious disease threat was the Zika virus. But the authors of the new study say the results could apply to the recent novel coronavirus (COVID-19) outbreak.

Hot time in the city: Urban lizards evolve heat tolerance

Faced with a gritty landscape of metal fences, concrete walls and asphalt pavement, city lizards in Puerto Rico rapidly and repeatedly evolved better tolerance for heat than their forest counterparts, according to new research. Studies that delve into how animals adapt in urban environments are still relatively rare. But anoles are becoming a model system for urban evolutionary research.

New acoustic smart material inspired by shark skin

Researchers created a new sharkskin-inspired smart material that allows shifts in acoustic transmission on demand using magnets. As a result the new material can achieve multiple properties in one structure by switching between states, for example transmitting and also damping external noise transmission in a submarine through a single device. This smart material can recreate properties intrinsic...
