Malfunction in spermatogenesis: Researchers uncover contribution of cylicin proteins to male fertility
For successful fertilization, sperm should move forward rapidly and be shaped correctly. The unique structure of the sperm cells forms during spermiogenesis. Now, researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research.....»»
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.....»»
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.....»»
Shedding light on snow"s crucial role in Earth"s climate system
EU researchers are braving extreme Arctic conditions to shed light on snow's crucial role in Earth's climate system......»»
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.....»»
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.....»»
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......»»
Discovery of egg"s immune-like attack on sperm mitochondria may aid fertility
Within minutes of fertilization, the egg of a fruit fly becomes a scene from the battle of the sexes. The egg attacks and destroys the cellular "power plants" (mitochondria) from the sperm that had fertilized it, so that only its own mitochondria rem.....»»
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......»»
Researchers highlight role "workhorse protein" plays in keeping nervous system running smoothly
A team of researchers from the University of Massachusetts Amherst is the first to show how proteins called "chaperones" are vital in ensuring that neurons can transmit signals to one another. When this neurotransmission breaks down, devastating dise.....»»
Hybrid dune experiment tests erosion resistance during storms
Last week, a 100-meter-long test dune was raised on the coast near Monster. A hybrid dune, consisting of a combination of sand and hard elements. Researchers from TU Delft are monitoring how different configurations erode during stormy weather condit.....»»
Sustainability not an important criterion in top executives" remuneration
A study by an international team of researchers from the University of Tübingen and the HEC business school in Paris has shown that the payment of bonuses to executive board members in large European corporations is only minimally influenced by whet.....»»
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune re.....»»
Why don"t more women choose to propose to their male partners?
The Christmas period isn't just for presents, sparkling lights and too much festive food—it's also prime time for couples to get engaged. And for heterosexual couples, this is likely to happen in a specific way. The man will do the asking......»»
Tech used by WWI flying aces inspires new cellular behavior discovery
Researchers at the University of Massachusetts Amherst have designed a new technology that takes inspiration from WWI fighter aircraft machine gun and propeller synchronization to manipulate cell behavior by precisely modulating the pH of the cell's.....»»
