A new study in Genome Biology and Evolution, published by Oxford University Press, finds that the African Swine Fever virus, currently circulating in Europe, is not the result of a recent introduction. Instead, the virus has been present in the region since 2007. Its current dramatic spread appears to be driven largely by people within Europe traveling longer distances. African Swine Fever virus is a highly virulent DNA virus that causes a severe hemorrhagic disease of the same name affecting both…
Some two-thirds of riders and drivers for food delivery and ride-hailing apps in the UK may work in fear of “unfair feedback” and experience anxiety over sudden changes to working hours, a new survey study led by the University of Cambridge suggests.* Three-quarters of riders and drivers in the study report anxiety over potential for income to drop, with over half (51%) saying they risk health and safety while working. Some 42% of delivery and driver gig workers say they…
Consensus on how mindset and surroundings shape therapy outcomes is an important step toward regulatory approval for use of drugs like MDMA and psilocybin in treatment of debilitating mental health conditions As psychedelics gain traction as potential treatments for mental health disorders, an international study led by researchers at McGill University, Imperial College London, and the University of Exeter stands to improve the rigour and reliability of clinical research. Up to now, psychedelic clinical trials have had what has been widely acknowledged…
In September 2023, a bizarre global seismic signal was observed which appeared every 90 seconds over nine days – and was then repeated a month later. Almost a year later, two scientific studies proposed that the cause of these seismic anomalies were two mega tsunamis which were triggered in a remote East Greenland fjord by two major landslides which occurred due to warming of an unnamed glacier. The waves were thought to have become trapped in the fjord system, forming…
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,…
University of Arizona astronomers have learned more about a surprisingly mature galaxy that existed when the universe was just less than 300 million years old – just 2% of its current age. What Does the James Webb Telescope Tell Us About the Universe? Ever since the launch of the James Webb Telescope, it has sailed across the starry universe, discovering galaxies formed around thirteen billion years ago—almost the inception of time itself! It possesses advanced infrared capabilities, much more evolved…

Could black holes help explain high-energy cosmic radiation? The universe is full of different types of radiation and particles that can be observed here on Earth. This includes photons across the entire range of the electromagnetic spectrum, from the lowest radio frequencies all the way to the highest-energy gamma rays. It also includes other particles such as neutrinos and cosmic rays, which race through the universe at close to the speed of light. Curiously, “cosmic rays” are not actually rays…
Laser Ion acceleration uses intense laser flashes to heat electrons of a solid to enormous temperatures and propel these charged particles to extreme speeds. These have recently gained traction for applications in selectively destroying cancerous tumor cells, in processing semiconductor materials, and due to their excellent properties – for imaging and fusion relevant conditions. Massive laser systems with several Joules of light energy are needed to irradiate solids for the purpose. This produces a flash of ions which are accelerated…
The elucidation of the biosynthetic pathway of ipecacuanha alkaloids shows how two distantly related plant species could develop the same substance independently Plants produce an enormous abundance of natural products. Many plant natural products are ancestry-specific and occur only in certain plant families, sometimes only in a single species. Interestingly, however, the same substances can sometimes be found in distantly related species. In most cases, however, only the end product is known and it is largely unclear how these substances…
Uncovering the genetic basis of purring in cats Kyoto, Japan — Whether you are lucky enough to have a cat companion or must merely live this experience vicariously through cat videos, Felis catus is a familiar and comforting presence in our daily lives. Unlike most other feline species, cats exhibit sociality, can live in groups, and communicate both with other cats and humans, which is why they have been humans’ trusted accomplices for millennia. Despite this intimacy, there is still…
Chlorinated organic substances can be converted into dioxins in the atmosphere Are the risks of hazardous chemicals being determined appropriately? In certain cases, apparently not–according to a study published in the journal Angewandte Chemie by a team of Chinese researchers. The study indicates that chlorinated volatile organic compounds on mineral dust particles in the atmosphere can be converted into highly toxic polychlorinated dibenzo-p-dioxins and dibenzofurans by sunlight. Hazardous chemicals are frequently assessed under national and international regulatory frameworks, which primarily…
A small deletion in a gene on the X-chromosome lies behind the fiery coats of ginger tabbies and the splotchy orange patches of calicos and tortoiseshell cats. Fukuoka, Japan – From Tama, Japan’s most famous stationmaster calico cat, to the lasagna-loving, ginger Garfield, cats with orange fur are both cultural icons and beloved pets. But their distinctive color comes with a genetic twist-most orange tabbies are male, while calicos and tortoiseshells are nearly always female. This pattern points to an…

CHAMPAIGN, Ill. — Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car…
Triboelectric nanogenerators (TENGs) are a transformative class of next-generation devices for energy conversion and self-powered sensing. Selecting appropriate triboelectric and conductive materials is crucial for optimizing TENG performance. In recent years, MXenes, especially Ti3C2 MXene, have become highly promising candidates for both triboelectric and conductive materials in TENGs. Although many studies (including research and review articles) have focused on TENG construction and performance, there is a significant gap in the literature: a comprehensive summary of MXene applications from a materials…
Oxygen defect engineering enables efficient sulfone production using molecular oxygen at low temperature Sulfones, a class of sulfur-containing compounds, are chemically derived from the selective oxidation of sulfides. While these compounds form the core of the pharmaceuticals, solvents and polymer industries, their chemical synthesis is often hindered by high reaction temperatures and extreme reaction conditions. Additionally, these also require costly additives and harsh solvents for production. Against this backdrop, a team of researchers from Japan introduced a new catalyst design,…

A combination of stressors, not sea levels alone, cause the demise of reefs New research led by the University of Sydney adds to our understanding of how rapidly rising sea levels due to climate change foreshadow the end of the Great Barrier Reef as we know it. The findings suggest the reef can withstand rising sea levels in isolation but is vulnerable to associated environmental stressors arising from global climate change. Led by Professor Jody Webster from the School of…
Flooding in coastal communities is happening far more often than previously thought, according to a new study from North Carolina State University and the University of North Carolina at Chapel Hill. The study also found major flaws with the widely used approach of using marine water level data to capture instances of flooding. “Government agencies and researchers use data from tide gauges to measure water levels in coastal areas, then use that data to estimate flood frequency in the region,”…
Frontiers in Ocean Sustainability author Dr. Mary Livingston reflects on her decades-long career as a marine scientist by Dr Mary Elizabeth Livingston In my recently published paper ‘My love affair with the sea’ I describe how from a very early age I fell in love with the sea and pursued that love throughout my younger years and at university, ending up with a 40-year career as a fisheries scientist.
