Researchers take "significant leap forward" with quantum simulation of molecular electron transfer
Researchers at Rice University have made a meaningful advance in the simulation of molecular electron transfer—a fundamental process underpinning countless physical, chemical and biological processes. The study, published in Science Advances, detai.....»»
3 underrated Amazon Prime Video movies you should watch this weekend (December 20-22)
The holiday season is here, and with it comes plenty of stress. If you’re looking to unwind, the best way to do that might be to find some time to watch a movie. Once you’ve done that, though, you’ve still got to pick the film you w.....»»
Volunteers should not become friends with patients, say Norwegian researchers
When a volunteer supports a patient, a special and often rather unequal relationship can develop between the helper and the person receiving the help. Researchers have now investigated this relationship and offer guidance on finding the right balance.....»»

Grapevine protein resembles animal ion transport function, researchers discover
Researchers at the University of Adelaide have discovered that a protein which mediates the transport of alkali metal ions, such as potassium, and halide ions across plant membranes acts similarly to a protein found in animals......»»
Genetically encoded biosensors measure living cells" charge in real time
Biological cells have many vital functions in the organism. For example, they produce proteins, carbohydrates and fats. But they are also responsible for detoxifying harmful molecules and transmitting signals and immune defense steps. A so-called red.....»»
Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
Dark energy "doesn"t exist" so can"t be pushing "lumpy" universe apart, physicists say
One of the biggest mysteries in science—dark energy—doesn't actually exist, according to researchers looking to solve the riddle of how the universe is expanding......»»
Programming cells: New RNA tool enhances precision in synthetic genetic circuits
Researchers have successfully developed a modular synthetic translational coupling element (SynTCE), significantly enhancing the precision and integration density of genetic circuits in synthetic biology. Their study was recently published in the jou.....»»
Clever trick to cook young stars detected for first time—astronomers highlight magnetic fields as the missing ingredient
The missing ingredient for cooking up stars in the same way you might steam your Christmas pudding has been spotted for the first time by astronomers. Much like a pressure cooker has a weight on top of its lid to keep the pressure in and get your fes.....»»

We’re about to fly a spacecraft into the Sun for the first time
"Quite simply, we want to find the birthplace of the solar wind." Almost no one ever writes about the Parker Solar Probe anymore. Sure, the spacecraft got some attention when it l.....»»
By looking at individual atoms in tooth enamel, researchers are learning what happens to our teeth as we age
Teeth are essential for helping people break down the food they eat, and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repa.....»»
New physics sim trains robots 430,000 times faster than reality
"Genesis" can compress training times from decades into hours using 3D worlds conjured from text. On Thursday, a large group of university and private industry researchers unveile.....»»
New "molecular flipbook" gives researchers the best look yet at ribosomal motion
At one time or another, most of us have played with a flipbook, using our thumbs to rapidly flip a series of pictures to create an illusion of movement......»»
Sugar solution matches antibiotics in treating cow infections
A concentrated sugar solution could be just as effective as antibiotics at treating a common infection in dairy cows, according to a new study led by researchers at Penn State. The results were recently published in the journal Frontiers in Veterinar.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Researchers unveil chip for quick antibiotic monitoring in water
Antimicrobial resistance (AMR) is a growing global health crisis because of microbes, such as bacteria, becoming resistant to antibiotics. A leading factor in this rise is the improper use and disposal of antibiotics in the environment......»»
