Researchers create light-powered yeast, providing insights into evolution, biofuels, cellular aging

You may be familiar with yeast as the organism content to turn carbs into products like bread and beer when left to ferment in the dark. In these cases, exposure to light can hinder or even spoil the process. In a new study published in Current Biology, researchers in Georgia Tech’s School of Biological Sciences … Read more

Scientists propose a self-organizing model of connectivity that applies across a wide range of organisms

Hebbian dynamics produce power–law connection strengths. Credit:bioRxiv (2022). DOI: 10.1101/2022.05.30.494086 A study by physicists and neuroscientists from the University of Chicago, Harvard and Yale describes how connectivity among neurons comes about through general principles of networking and self-organization, rather than the biological features of an individual organism. The study, titled “Heavy–tailed neuronal connectivity arises from … Read more

Dogs may wag their tails so much due to rhythm-loving humans, scientists say | Animal behaviour

Whether it is an elegant swish or a furious oscillation, tail wagging is ubiquitous among dogs. Now researchers have suggested it may have become commonplace during canine domestication because humans love its rhythm. It is thought humans domesticated dogs sometime between 15,000 and 50,000 years ago – a process that has led to a fervent … Read more

Core-shell ‘chemical looping’ boosts efficiency of greener approach to ethylene production

Ethylene is sometimes called the most important chemical in the petrochemical industry because it serves as the feedstock for a huge range of everyday products. It’s used in the production of antifreeze, vinyl, synthetic rubber, foam insulation, and plastics of all kinds. Currently, ethylene is produced through an energy- and resource-intensive process called steam cracking, … Read more

Moon age daydream: modern lunar exploration

Credit: Pixabay/CC0 Public Domain Japan, whose unmanned “sniper” probe will attempt a lunar landing on Saturday, is one of many countries and private companies launching new missions to the moon. It is a feat so far only achieved by four nations—the United States, the Soviet Union, China and most recently India—with spacecraft often losing communication … Read more

A moment that changed me: my husband and I split up – and I started walking 15,000 steps a day | Health & wellbeing

One sweltering evening in 2020 during the first lockdown, as we sat drinking wine in the shed at the end of the garden, my husband and I came to the surprise decision to finish our 17-year relationship. “It’s the end of the line, isn’t it?” I ventured. “I know,” he replied, looking down at his … Read more

Scabies Is Making a Comeback

The high number of cases in the UK also reflects the difficulty of eradicating an outbreak, says Jo Middleton, a research fellow at Brighton and Sussex Medical School, who is involved in scabies research in the UK and around the globe. Bedding and furniture need to be completely decontaminated, while medicines like permethrin are not … Read more

Squishy, metal-free magnets to power robots and guide medical implants

“Soft robots,” medical devices and implants, and next-generation drug delivery methods could soon be guided with magnetism — thanks to a metal-free magnetic gel developed by researchers at the University of Michigan and the Max Planck Institute for Intelligent Systems in Stuttgart, Germany. The material is the first in which carbon-based, magnetic molecules are chemically … Read more
