New study reveals how human astroviruses bind to humans cells and paves the way for new therapies and vaccines Human astroviruses are a leading viral cause of the stomach bug—think vomiting, diarrhea, and fever. It often impacts young children and older adults, leading to vicious cycles of sickness and malnutrition, particularly for those in low and middle income countries. It’s very commonly found in wastewater studies, meaning it’s frequently circulating in communities. As of now, there are no vaccines for…
UC San Diego-led team discovers new method for producing large amounts of color-changing, nature-inspired pigment in the lab Scientists at UC San Diego have moved one step closer to unlocking a superpower held by some of nature’s greatest “masters of disguise.” Octopuses, squids, cuttlefish and other animals in the cephalopod family are well known for their ability to camouflage, changing the color of their skin to blend in with the environment. This remarkable display of mimicry is made possible by…
Scientists uncover how support cells, once thought harmless, send damaging signals that weaken the heart Heart failure (HF) is one of the leading causes of death and disability worldwide, affecting millions of people and placing an enormous burden on healthcare systems. The disease occurs when the heart can no longer pump blood efficiently, leaving patients short of breath, fatigued, and at risk of life-threatening complications. For decades, scientists have focused on studying cardiomyocytes—the heart’s muscle cells responsible for pumping blood—believing…
The appearance of a hot sauce or pepper doesn’t reveal whether it’s mild or likely to scorch someone’s taste buds. So, researchers made an artificial tongue to quickly detect spiciness. Inspired by milk’s casein proteins, which bind to capsaicin and relieve the burn of spicy foods, the researchers incorporated milk powder into a gel sensor. The prototype, reported in ACS Sensors, detected capsaicin and pungent-flavored compounds (like those behind garlic’s zing) in various foods. “Our flexible artificial tongue holds tremendous…
Study reveals new information about how to prevent chronic inflammation from zombie-like cells that accumulate with age In humans and other multicellular organisms, cells multiply. This defining feature allows embryos to grow into adulthood, and enables the healing of the many bumps, bruises and scrapes along the way. Certain factors can cause cells to abandon this characteristic and enter a zombie-like state known as senescence where they persist but no longer divide to make new cells. Our bodies can remove…
University of Arizona neuroscientists studying the brains of songbirds have found that aging alters the gene expressions that control the birds’ song. The finding could lead to earlier diagnoses and better treatments for human neurodegenerative disorders such as Parkinson’s disease and Alzheimer’s disease, which are known to hinder vocal production in their early stages. The study, published in the journal Neurobiology of Aging, found that networks of interacting genes, in a region of the bird’s brain involved with singing, dramatically…
A new type of antibody which stimulates the immune system to target cancer cells slows tumor growth, according to new research Antibody treatment which activates the patient’s own immune system against cancer, known as immunotherapy, is increasingly being investigated as an alternative for chemotherapy and radiotherapy. This is because it specifically targets the cancer cells, which reduces the side effects seen with more conventional therapies. Tumours, such as some breast and ovarian cancers, can express the marker HER2. HER2 is…
Gemini North’s MAROON-X instrument finds evidence for four mini-Earth exoplanets around our famous cosmic neighbor Barnard’s Star For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star system to Earth [1]. Barnard’s Star is classified as a red dwarf — low-mass stars that often host closely-packed planetary systems, often with multiple rocky planets. Red dwarfs are extremely numerous in the Universe, so scientists…

Heliconius are a group of tropical butterflies known for their wide variety of wing patterns and colors, which act as a warning to predators. Because wing coloration is crucial for their…
Understanding children’s subjective experiences through color As a child, did it ever occur to you that your perception of color differed from that of others? It’s quite common to have this thought, but it turns out that the human color experience may be more universal than we previously believed. In psychology and neuroscience, the relationship between subjective experience, such as how we perceive color, and physical brain activity has remained an unresolved problem. Furthermore, due to their limited language abilities,…

These results remained significant after statistically adjusting for chronotype. “Our study demonstrated that individuals who habitually procrastinate their bedtime were actually less likely to…
Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

Using a global network of telescopes, astronomers have detected the lowest-mass dark object yet found in the universe. Finding more such objects and understanding their nature could rule out some theories about the nature of dark matter, the mystery substance that makes up about a quarter of the universe. The work is described in two papers published Oct. 9 in Nature Astronomy and Monthly Notices of the Royal Astronomical Society. Because the object does not emit any light or other radiation, it was…
Scientists digging through data collected by the Cassini spacecraft have found new complex organic molecules spewing from Saturn’s moon Enceladus. This is a clear sign that complex chemical reactions are taking place within its underground ocean. Some of these reactions could be part of chains that lead to even more complex, potentially biologically relevant molecules. Published today in Nature Astronomy, this discovery further strengthens the case for a dedicated European Space Agency (ESA) mission to orbit and land on Enceladus….

Unless you’ve owned reptiles, you might not know that many of them “pee” crystals. Researchers publishing in the Journal of the American Chemical Society investigated the solid urine of more than 20 reptile species and found spheres of uric acid in all of them. This work reveals how reptiles uniquely package up and eliminate crystalline waste, which could inform future treatments for human conditions that also involve uric acid crystals: kidney stones and gout. Most living things have some sort…
Enabled by a new high-resolution mapping technique, the findings overturn a long-held belief that the genome loses its 3D structure when cells divide CAMBRIDGE, MA — Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that as division occurs, the genome loses the distinctive 3D internal structure that it typically forms. Once division is complete, it…
Researchers at the University of North Carolina have created microscopic soft robots shaped like flowers that can change shape and behavior in response to their surroundings, just like living organisms do. These tiny “DNA flowers” are made from special crystals formed by combining DNA and inorganic materials. They can reversibly fold and unfold in seconds, making them among the most dynamic materials ever developed on such a small scale. Each flower’s DNA acts like a tiny computer program, telling it…
Researchers have created a polymer “Chinese lantern” that can snap into more than a dozen curved, three-dimensional shapes by compressing or twisting the original structure. This rapid shape-shifting behavior can be controlled remotely using a magnetic field, allowing the structure to be used for a variety of applications. The basic lantern object is made by cutting a polymer sheet into a diamond-like parallelogram shape, then cutting a row of parallel lines across the center of each sheet. This creates a…

New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
Earthquakes in the American state of Utah, the Soultz-sous-Forêts region of France or in the Dutch province of Groningen should not be able to occur even if the subsurface has been exploited for decades. This is because the shallow subsurface behaves in such a way that faults there become stronger as soon as they start moving. At least that is what geology textbooks teach us. And so, in theory, it should not be possible for earthquakes to occur. So why…
