The Mediterranean Sea is widely perceived as having a low tsunami risk. History and recent modeling technology have demonstrated that destructive waves have already hit the French coast and could do so again. The results of a project carried out in Nice and along the French Riviera show why anticipation and preventive evacuation measures remain the only truly effective means of saving lives. [...]
Photoreceptors are specialized cells in the eye that convert light energy into neural signals. Several diseases that cause irreversible vision loss, including age-related macular degeneration, retinitis pigmentosa and retinal detachment, are associated with dying photoreceptors. While there are many molecular pathways that result in cell death, there are also many that try to keep the cell alive. [...]
Monoclonal antibodies are widely used to treat diseases ranging from cancer to autoimmune disorders. The safety and efficacy of these biologic drugs depend on maintaining their correct three-dimensional organization, known as their higher-order structure (HOS). [...]
The More You Know: This week, researchers successfully reconstructed videos from the brain activity of mice. According to a new study, female birds are more likely to sing when their extended families help with childcare. And mathematicians have disproven a decades-old classical geometry rule by constructing two compact, self-contained torus objects that have the same metric and mean curvature but are structurally different on a global scale. So that's neat. [...]
A team of US researchers has gained new insights into how large protein molecules consistently fold themselves into useful shapes. Using a new approach to fluorescence microscopy, Hoi Sung Chung and colleagues at the National Institute of Diabetes and Digestive and Kidney Diseases have shown that the process likely occurs through the coordinated folding of many different parts of each biomolecule. Their results are published in Physical Review Letters. [...]
Researchers at the University of New Hampshire have documented the farthest trek of a young female fisher (Pekania pennanti) moving 118 kilometers (over 73 miles) from Durham to the outskirts of Lincoln, a small town in New Hampshire's White Mountains. This trip marks the longest known recorded dispersal for the species. [...]
New research co-led by Liu-Qin Yang, a professor of psychology at Portland State University (PSU), suggests that the true damage of a toxic boss goes far deeper than a bad mood—it fundamentally alters how employees perceive their own humanity. Published in the Journal of Occupational Health Psychology, the study identifies "organizational dehumanization" as the primary mechanism that strips employees of their agency, leading to severe burnout and a collapse in workplace collaboration. [...]
Microbial bioelectronic sensors use living bacteria that can create an electrical signal in response to the presence of a target substance, or analyte. These types of sensors offer many advantages over other types of biosensors based on proteins and enzymes: The bacteria can perform multiple functions, survive in a variety of environments and even grow and regenerate for potential long-term use. [...]
In 2000, a group of STRI botanists collected samples of all the plants from the genus Clusia they could find in Panama to find out how the different species in this group are related. [...]
Math nerds and dessert enthusiasts unite to celebrate Pi Day every March 14, the date that represents the first three digits of the mathematical constant pi. [...]
A global database documenting the location of critical habitats for sharks, rays, and chimeras has recently expanded to include Australia, with years of extensive research by Charles Darwin University (CDU) contributing to this crucial digital record. [...]
More than 7.5 million people immerse themselves in lakes, rivers, seas and lidos every year in the UK. But getting in the water means getting in pollution too for most outdoor swimmers. Raw sewage was discharged into UK waters for 4.7 million hours during 2024. But sewage is only part of the water pollution problem. Rain washing into rivers and streams contains fertilizers, pesticides and animal waste from farmlands, forever chemicals from car tires, plus drugs from our own bodies. Industry deregulation and privatization have produced a water crisis. [...]
The performance horse industry had a problem: Some of their most beloved and sought-after mares simply couldn't have foals safely. To make matters more complicated, in vitro fertilization (IVF) had not yet produced a healthy equine embryo, despite years of success in other species like cattle. [...]
In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an otherworldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together at the same time and follow the exact same pattern—a synchronous light show you can see only in few places in the United States. [...]
Wet wipes conveniently clean and sanitize soiled surfaces and skin. Because some labels do not clearly indicate how consumers should dispose of them, these small cloths are often flushed down the toilet and released by sewage plants into waterways. Now, researchers report in ACS ES&T Water that some of these wipes break down into plastic fibers, or microplastics, that could harm aquatic life. [...]
Dragonfly integration and testing—the activities involved in assembling the mission's rotorcraft lander and testing it for the rigors of launch and extreme conditions of space—is officially underway in clean rooms and control rooms at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. [...]
Wildlife populations that become small and isolated, often due to habitat loss, inevitably experience inbreeding which can lead to the loss of fitness and eventual extinction. One solution is to perform a genetic rescue: a management intervention where new blood is brought in by introducing outsiders to a population to reduce inbreeding and restore diversity. But how do researchers know the inbreeding problem has been solved? [...]
Multiferroic metals are materials that exhibit both electric polarization and magnetic order in the same crystal—a state known as multiferroicity. Because these properties coexist, they can interact through magnetoelectric (ME) coupling, allowing electric fields to influence magnetism. [...]
MLIP calculations successfully identify suitable dopants for a novel photocatalytic material, report researchers from the Institute of Science Tokyo. As demonstrated in their study, published in the Journal of the American Chemical Society, a materials informatics approach could predict which ions can be stably introduced into orthorhombic Sn3O4, a promising and recently discovered photocatalytic tin oxide. [...]
An international team from China and Italy has reported a possible cosmic encore to the landmark 2017 multi-messenger discovery. In November 2024, the LIGO-Virgo-KAGRA observatories detected gravitational waves from a binary black hole merger, designated S241125n. Remarkably, just seconds later, satellites recorded a short gamma-ray burst (GRB) from the same region of the sky. [...]
The customer is always right. It's the first rule of customer service, one that often means "I'm sorry" is the de facto response if mistakes are made. But a new study published in the Journal of Consumer Research indicates that the age-old maxim might not hold water. In fact, apologies might actually make things worse, both for businesses and customers. [...]
A new LMU study shows how proteins function reliably even without a stable 3D structure—and the crucial importance not only of short sequence motifs, but also of chemical characteristics. [...]
A tropical insect has been found to change color from vivid hot pink to green within a fortnight, which scientists believe may mimic the young leaves of rainforest plants. The findings, published this week in the journal Ecology, focuses on Arota festae, a leaf-masquerading katydid also known as a "bush cricket," native to Panama, Colombia and Suriname. [...]
A research team associated with the European project DEATHREVOL has published a study in the journal Scientific Reports that proposes new analytical tools to better understand how fractures of the human skull occur and how these injuries can be interpreted in order to distinguish between accidental trauma and trauma resulting from interpersonal violence. The study involved researchers from Centro Nacional de Investigación sobre Evolución Humana (CENIEH) and from the University of Burgos and Rey Juan Carlos University (Madrid). [...]
Scientists from the National University of Singapore (NUS) have developed a biochemical technique that captures fleeting "handshakes" between newly made proteins and the cellular helpers. These short interactions are important because they can determine whether a protein turns out healthy and useful or is faulty and in need of removal. The research has been published in the journal Molecular Cell. [...]
It's long been assumed that for an organism to learn, remember or draw conclusions, it needs a brain. But mounting evidence, including a recent Cognitive Science study, challenges that assumption, suggesting that neurons might not be necessary for complex information processing. [...]
Two locations have been identified as the most likely entry points into Australia for a disease that poses a huge risk to the beef and dairy industries. A University of Queensland-led team has built the first geospatial model to map where insects carrying lumpy skin disease virus (LSDV) could arrive either blown by strong wind or carried on ships. [...]
An international team of researchers has achieved a breakthrough in the production of doxorubicin, a vital chemotherapy agent. The study identifies and resolves molecular "bottlenecks" that have limited the natural production of this drug for over 50 years. The research is published in Nature Communications. [...]
There is a near-infinite number of material candidates out there—and simply not enough time to hunker down in the lab and test them all. Thankfully, researchers have a variety of tools (such as AI) at their disposal to streamline what would otherwise be a time-consuming process of trial-and-error. [...]
Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large cancer drugs enter tumor cells and cause them to self-destruct. Dubbed "Sonoporation-assisted Precise Intracellular Nanodelivery"—or SonoPIN for short—the technology caused 50% of targeted cancer cells in a benchtop experiment to self-destruct, while leaving 99% of non-targeted cells healthy. The results show promise for precisely delivering a wide variety of large-molecule therapeutics to cells with few off-target effects. The research appears in Proceedings of the National Academy of Sciences. [...]
