Phys.org / Gold-MXene catalyst converts nitrate to ammonia using sunlight and 1.5 volts

Plants need nitrogen fertilizers, which are usually ammonia-based. Ammonia is therefore one of the most important chemical products. However, its production is currently extremely energy-intensive. An international team from ...

Phys.org / Two antibody gene systems may help explain vesper bats' unusual viral tolerance

It is a mystery that has puzzled scientists for years. How can the world's only winged mammals carry viruses that cause severe disease while rarely becoming seriously ill themselves?

Phys.org / Flexible DNA directs proteins into atomically ordered crystals, overturning crystallization assumptions

For decades, scientists have largely relied on painstaking trial and error to coax proteins into crystalline forms. Crystallization enables scientists to determine the molecular structures of proteins, which can provide a ...

Phys.org / Problematic internet users are crabbier, more stressed and more tempted than the rest of us

People described as "problematic" internet users report higher stress, worse mood and greater neglect of other activities than those who surf the web sparingly, according to a study published in PLOS One by Silke M. Müller ...

Phys.org / Repeating distance patterns let optical systems tackle large optimization problems

From planning transportation networks to organizing massive datasets, many of society's most important challenges boil down to an optimization problem: finding the best solution among an enormous number of possibilities. ...

Phys.org / Finding order in the inner chaos of our cells: Shape-shifting proteins get a design tool

The vast majority of proteins in our bodies contain regions that are in a constant state of wiggling, shape-shifting every few nanoseconds to completely change how they look. Information on how these shape-shifting proteins ...

Phys.org / Like a molecular shrink ray, AI tool redesigns proteins without sacrificing function

Researchers at Duke University School of Medicine have developed an artificial intelligence framework that can redesign proteins on a scale previously seen only in natural evolution. The tool can create shorter, longer and ...

Phys.org / Gene discovery could shave years off avocado breeding

Scientists have found a genetic switch that could shave years off avocado breeding by allowing researchers to identify one of a young tree's most important traits long before it flowers.

Phys.org / Oil beetle larvae smell like flowers to manipulate bees and sneak into their nests

For the first time, a research team from the Max Planck Institute for Chemical Ecology and Friedrich Schiller University in Jena, Germany, has demonstrated that insects can mimic floral scents to manipulate pollinators.

Phys.org / Why the hepatitis E virus cannot infect mice

Many viruses can infect both humans and animals, including hepatitis E virus. This virus is often transmitted to humans via contaminated meat products, such as by ingesting raw or undercooked pork or wild game. However, mouse ...

Phys.org / Captured carbon dioxide could yield strong, flexible plastics designed for recycling

Researchers at Colorado State University have developed a process to transform naturally occurring, highly stable carbon dioxide into recyclable, high-performance materials that could replace today's plastics in many situations. ...

Phys.org / Mosquitoes are rapidly activating enzymes against common insecticide, researchers warn

Traditionally, public health programs have relied on chemicals for mosquito management, which may be why combating mosquitoes is becoming more difficult. Over time, insecticides trigger biochemical and genetic variations ...
