Everyday levels of antibiotics in the environment may accelerate the global spread of resistance, new study finds

2025-11-14
Antibiotic resistance is widely recognized as one of the most urgent public health challenges of the twenty first century. Now, a new study shows that even very small amounts of antibiotics that commonly appear in soil, rivers, wastewater, and agricultural runoff may significantly accelerate the spread of antibiotic resistance genes among bacteria. The research, published in Biocontaminant, investigates how four typical antibiotics found in the environment influence both vertical and horizontal gene transfer, the two major pathways through which bacteria pass on resistance. The team examined tetracycline, ...

What happens to ecosystems when you restore iconic top predators? It’s more complicated than you might think.

2025-11-13
Across North America, mountain lions, bears, and gray wolves have made a remarkable comeback over the last 50 years. Once nearly exterminated, these animals have been recovering their populations and returning to the landscapes they historically roamed, thanks to protections like the Endangered Species Act, hunting limits, and reintroduction programs. The ecological impact of restoring these large carnivores is potentially huge, in part because of the way they could help to balance ecosystems by keeping prey populations under control.    One ...

Mystery of how much squid short-finned pilot whales eat resolved

2025-11-13
How much squid do short-finned pilot whales (Globicephala macrorhynchus) off the coast of Hawai’i need to consume each day to survive and are there sufficient squid to sustain the population? Knowing these basic facts is essential in the fight to protect populations. Researchers from the USA, Spain, Australia and Denmark reveal in Journal of Experimental Biology that individual Hawaiian short-finned pilot whales consume between 82 and 202 squid per day, adding up to a total of 88,000 tonnes of squid per year for the entire ...

New frog-like insects leap into the science books

2025-11-13
Seven new species of a distinctive frog-like insect have been discovered by a scientist from Anglia Ruskin University (ARU) in Cambridge, England. Belonging to the genus Batracomorphus, the seven previously unknown species of leafhopper were found by Dr Alvin Helden during fieldwork in the tropical rainforest of Uganda. The name Batracomorphus derives from the Greek for “frog-shaped”, and these leafhoppers are mostly green, possess large eyes and jump using their long hind legs, which are tucked alongside their bodies like frogs. The details of Dr Helden’s discoveries have been published in the journal Zootaxa and they are the first new ...

Researchers reveal intricate control system for key immune gene

2025-11-13
SAN FRANCISCO—The immune system faces a delicate balancing act: it must be aggressive enough to fight infections and cancer, yet restrained enough to avoid attacking the body’s own tissues. More than two decades ago, researchers identified a gene called FOXP3 as playing a critical role in maintaining this balance and preventing autoimmune disease—work that garnered this year’s Nobel Prize in Physiology or Medicine. Now, scientists at Gladstone Institutes and UC San Francisco (UCSF) have mapped the intricate network of genetic switches ...

New DNA analysis approach could transform understanding of disease evolution

2025-11-13
Research institutions around the world house valuable genetic information that could help unlock countless medical mysteries. However, because DNA degrades over time, it is difficult for researchers to analyze DNA samples older than 20 years using conventional analytical approaches. Although modern technologies have transformed researchers’ ability to learn about disease, these technologies have primarily been used on modern genetic samples. The ability to study genetic data from earlier decades has been exceedingly limited, which hinders researchers’ understanding of old diseases and why changes in ...

Arctic fossils reveal complex and diverse Early Triassic marine vertebrate communities

2025-11-13
Just a few million years after the end-Permian mass extinction event (EPME), aquatic reptiles and other vertebrates had recovered to form thriving and diverse oceanic ecosystems, according to a study of an Early Triassic-age fossil site in the Arctic. The findings challenge previous assumptions of a slow and gradual establishment of mid-Triassic marine communities and suggest that vertebrate evolution paralleled the rapid resurgence of invertebrate life in the Early Triassic. The EPME, which occurred roughly 251.9 million years ago (Ma), wiped out upwards of 90% of all marine species on Earth. It has long been thought that recovery of ocean ecosystems following this event was slow, taking ...

Ancient DNA shows dogs joined human migrations and trade

2025-11-13
As human groups migrated and settled across Holocene Eurasia, dogs often traveled with them, researchers report in a new genomic study – and sometimes dogs were traded among populations. The study reveals the integral role these animals played in culture and exchange. For at least the last 11,000 years, dogs and humans have lived side-by-side. However, the true antiquity of their association with humans remains elusive. Some evidence suggests that major dog lineages in different parts of the world appear to have diversified thousands of years earlier, suggesting that these dogs may have traveled with humans as they colonized different parts of Europe, ...

Magnetically guided microrobots for targeted drug delivery

2025-11-13
A magnetically guided microrobotics system is capable of navigating the body’s intricate passageways and vasculature to deliver drugs with pinpoint accuracy, according to a new study. The novel system could enable safer, targeted drug treatments that minimize unwanted side effects. Systemic drug treatments often cause unwanted side effects due to off-target exposure and account for nearly one-third of failures in clinical trials, illustrating the need for precise, targeted drug delivery strategies. To address this, researchers have worked to develop magnetic micro- and nanorobots designed to deliver drugs directly to diseased tissues. Advances in materials ...

Microrobots finding their way

2025-11-13
Every year, 12 million people worldwide suffer a stroke; many die or are permanently impaired. Currently, drugs are administered to dissolve the thrombus that blocks the blood vessel. These drugs spread throughout the entire body, meaning a high dose must be administered to ensure that the necessary amount reaches the thrombus. This can cause serious side effects, such as internal bleeding. Since medicines are often only needed in specific areas of the body, medical research has long been searching for a way to use microrobots to deliver pharmaceuticals to where they need to be: in the case of a stroke, directly to the stroke-related thrombus. Now, a ...

‘Beautiful energy sandwich’ could power next-generation solar and lighting

2025-11-13
Researchers have achieved a new level of control over the atomic structure of a family of materials known as halide perovskites, creating a finely tuned ‘energy sandwich’ that could transform how solar cells, LEDs and lasers are made. Due to their remarkable ability to absorb and emit light, and because they are cheaper and can be configured to convert more of the solar spectrum into energy than silicon, perovskites have long been touted as a potential replacement for silicon in solar cells, LEDs and quantum technologies. However, their instability and durability has, so far, largely limited perovskite devices to the laboratory. ...

Which came first: The sponge or the comb jelly? HHMI scientists weigh in

2025-11-13
In the world of phylogenetics, there’s team sponge and team comb jelly. Which creature roots the animal tree of life — the simple sponge or the more complex comb jelly — has stirred fierce debate among phylogeneticists, researchers who study evolutionary history. Scientists long assumed the muscle-less and neuron-less sponges gave rise to more complex organisms, including humans. But genomic analyses in 2008 comparing hundreds of genes from many different animals and their relatives delivered ...

Extensive dog diversity millennia before modern breeding practices

2025-11-13
A groundbreaking archaeological study has revealed when domestic dogs first began to show the remarkable diversity that characterises them today.  By applying cutting-edge shape analysis to hundreds of archaeological specimens spanning tens of thousands of years, researchers have traced the emergence of distinct dog forms deep into prehistory, pinpointing the moment dogs began to diversify in size and shape - at least 11,000 years ago. These findings challenge long-standing assumptions that canine diversity is largely a recent phenomenon shaped by selective breeding, ...

Oldest oceanic reptile ecosystem from the Age of Dinosaurs found on Arctic island

2025-11-13
The fossils were found in 2015, but took nearly a decade of painstaking work to excavate, prepare, sort, identify, and analyse. The long-awaited research findings have now been published by a team of Scandinavian palaeontologists from the Natural History Museum at the University of Oslo, and the Swedish Museum of Natural History in Stockholm. Spitsbergen in the Svalbard archipelago is world famous for producing marine fossils from the beginning of the Age of Dinosaurs. These are preserved in rock layers that were once mud at ...

Scientists call on better regulation for chemical cocktails in Europe

2025-11-13
In a policy brief published in Science, scientists call on European Union for a new approach to protect people and nature from the hidden risks of chemical cocktails. Every day, people and all other living organisms are potentially exposed to dozens or even hundreds of chemicals – from plastics and pesticides to cosmetics and cleaning agents. While each chemical may individually meet safety standards, their combined effects can quietly add up. A new policy brief published in Science argues that current chemical ...
