The world got its first close-up look at a Mars landing on Friday, as NASA released a stunning picture of its newest rover being lowered onto the dusty red surface.
This week's killer freeze in the U.S. was no surprise.
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the realization of...
Microorganisms possess natural product biosynthetic gene clusters (BGCs) that may harbor unique bioactivities for use in drug development and agricultural applications. However, many uncharacterized microbial BGCs remain inaccessible. Researchers at University of Illinois Urbana-Champaign previously demonstrated a technique using transcription factor decoys to activate large, silent BGCs in...

Duke researchers have been studying something that happens too slowly for our eyes to see. A team in biologist Philip Benfey's lab wanted to see how plant roots burrow into the soil. So they set up a camera on rice seeds sprouting in clear gel, taking a new picture every 15 minutes for several days after germination.
A survey by a Boston University researcher of nearly 33,000 college students across the country reveals the prevalence of depression and anxiety in young people continues to increase, now reaching its highest levels, a sign of the mounting stress factors due to the coronavirus pandemic, political unrest, and systemic racism and inequality.
Northwestern University synthetic biologist Joshua Leonard used to build devices when he was a child using electronic kits. Now he and his team have developed a design-driven process that uses parts from a very different kind of toolkit to build complex genetic circuits for cellular engineering.
Scientists have discovered the first evidence of protein folding driven by liquid-liquid phase separation, a phenomenon in which fluids form into microscopic droplets and separate inside cells—like drops of oil in water.

A leaked scientific report jointly prepared by Israel’s health ministry and Pfizer claims that the company’s covid-19 vaccine is stopping nine out of 10 infections and the country could approach herd immunity by next month. The study, based on the health records of hundreds of thousands of Israelis, finds that the vaccine may sharply curtail transmission of the coronavirus. “High...

Adam Steltzner, the chief engineer on the Perseverance project, said his team was ‘overwhelmed with excitement and joy’ as he revealed new colour photographs beamed back from Nasa’s Perseverance roverNasa scientists release new images of Perseverance rover on Mars at news briefingNasa scientists hail Perseverance rover’s arrival on Mars with stunning images Continue...
A research team has successfully developed a technique to reach near-unity efficiency of SHEL by using an artificially-designed metasurface.
Disorders of the cells' energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on mitochondrial function to find future treatments. A new study shows how an important molecule inside the mitochondria affects their function in mice and fruit flies. The study adds valuable knowledge on formerly relatively unexplored protein...
Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists have now shown what the speed limit is for complex quantum operations. The results are important for the realization of quantum computers, among other things.
A new study, in which the Andalusian Earth Sciences Institute (IACT) (CSIC-UGR) participated, has described for the first time a key stage in the beginning of the great glaciations and indicates that it can happen to our planet in the future. The study claims to have found a new connection that could explain the beginning of the ice ages on Earth.
A gene linked to unusually long lifespans in humans protects brain stem cells from the harmful effects of stress, according to a new study.
A new study found consuming a high number of refined grains, such as croissants and white bread, is associated with a higher risk of major cardiovascular disease, stroke and early death.
Researchers have found that elevated concentrations of proteins within the droplets triggered a folding event, increasing the potential for protein aggregation -- or misfolding -- which has been linked to neurological diseases including Alzheimer's disease and amyotrophic lateral sclerosis (ALS).
Car-sized vehicle designed to seek signs of life is pronounced ‘healthy’ after dramatic descent to surface of the red planetNasa scientists have said the Perseverance Mars rover is “healthy” and is beaming back many stunning new images from the surface of the planet, promising significant scientific discoveries ahead.
