Viruses found to use intricate 'treadmill' to move cargo across bacterial cells: State-of-the-art technologies reveal bacterial cells organized like human cells, offering insights for new phage therapies on untreatable infections
Now, using advanced technologies to explore the inner workings of bacteria in unprecedented detail, biologists at the University of California San Diego have discovered that in fact bacteria have more in common with sophisticated human cells than previously known. Publishing their work June 13 in the journal Cell, UC San
How multi-celled animals developed: Evolutionary discovery to rewrite textbooks
Using new technology to investigate how multi-celled animals developed, their findings revealed a surprising truth.Professor Bernie Degnan said the results contradicted years of tradition.
Earth's heavy metals result of supernova explosion, research reveals
In a finding that may overthrow our understanding of where Earth's heavy elements such as gold and platinum come from, new research by a University of Guelph physicist suggests that most of them were spewed from a largely overlooked kind of star explosion far away in space and time from
Origin of life: A prebiotic route to DNA
How were the building-blocks of life first formed on the early Earth? As yet, only partially satisfactory answers to this question are available.
Two hours a week is key dose of nature for health and wellbeing
Research led by the University of Exeter, published in Scientific Reports and funded by NIHR, found that people who spend at least 120 minutes in nature a week are significantly more likely to report good health and higher psychological wellbeing than those who don't visit nature at all during an
New evidence links ultra-processed foods with a range of health risks: Policies that limit ultra-processed food intake are urgently needed, say researchers
The researchers say further work is needed to better understand these effects, and a direct (causal) link remains to be established, but they call for policies that promote consumption of fresh or minimally processed foods over highly processed foods. Ultra-processed foods include packaged baked goods and snacks, fizzy drinks, sugary

How old are your organs? To scientists' surprise, organs are a mix of young and old cells: Scientists discover cellular structures with extreme longevity, leading to insights for age-associated diseases
"We were quite surprised to find cellular structures that are essentially as old as the organism they reside in," says Salk Vice President, Chief Science Officer Martin Hetzer, senior author and professor. "This suggests even greater cellular complexity than we previously imagined and has intriguing implications for how we think
The fellowship of the wing: Pigeons flap faster to fly together
Birds that fly in 'V'-formations, such as geese, are able to conserve energy by flying in aerodynamically optimal positions.
Small cluster of neurons is off-on switch for mouse songs: With precise control, researchers could make a mouse sing or not on command
In fact, they now understand these neurons well enough to be able to make a mouse sing on command or to silence it so that it can't sing, even when it wants to impress a mate.
