Common patterns found among scientists with remarkable early-career citation success

A new analysis of data on scientists with exceptional early-career success—according to a metric known as citation impact—has identified common characteristics among them, some of which could also be indicators of problematic or fraudulent behaviors. John Ioannidis of Stanford University, U.S., presents these findings in the open-access journal PLOS One on August 6, 2025. Citation impact reflects a scientist’s overall influence in their field, which depends, in part, on the number of ...

Toxic well water will affect household pets first, new study finds

Dogs drink water wherever they happen to find it — a puddle, a pond, a toilet. But the stuff in their actual water bowls almost always comes from the same tap their owners use. When that water is contaminated, both dogs and humans may suffer. The risk is especially high for the 15 million American households that rely on private wells, according to a new Virginia Tech study in the journal PLOS Water. In dog drinking water sampled from wells across the country, 64 percent contained excessive levels of at least one potentially toxic heavy metal, such as lead, iron, sulfur, or arsenic. Whatever’s ...

Changes to El Niño occurrence causing widespread tropical insect and spider declines

Arthropods, including insects and spiders, make up the vast majority of animal species on the planet. Despite their small size they are irreplaceable contributors to the health of natural habitats, as well as vital food sources for birds and other larger animals. But, arthropods may be declining globally. There is some evidence to support reduced numbers of species in temperate regions of the Northen Hemisphere. In the tropics, however, evidence for arthropod declines has so far been limited. A recent international collaboration of scientists has attempted to find this missing evidence, with the findings published in Nature. The ...

Archaeologists find oldest evidence of humans on ‘Hobbit’s’ island neighbor – who they were remains a mystery

Recent findings, made by Griffith University researchers, show that early hominins made a major deep-sea crossing to reach the Indonesian island of Sulawesi much earlier than previously established, based on the discovery of stone tools dating to at least 1.04 million years ago at the Early Pleistocene (or ‘Ice Age’) site of Calio. Budianto Hakim from the National Research and Innovation Agency of Indonesia (BRIN) and Professor Adam Brumm from the Australian Research Centre for Human Evolution at Griffith University led the ...

Small-world networks can mitigate ESG controversies for multinationals, suggests new study

Multinational enterprises (MNEs) can negate supplier-induced environmental, social and governance (ESG) controversies by setting up ‘small-world’ networks, according to new research co-authored by Bayes Business School. Globalising supply chains has become a dominant strategy for MNEs. Benefits include lower costs of labour and distribution, and greater scope for innovation. However, long-distance operations also carry associated risks. Contrasting ethical standards of suppliers in different areas of the world can lead to ...

Seeing with fresh eyes: Snails as a system for studying sight restoration

KANSAS CITY, MO—August 6, 2025—The eye of the apple snail is unusually similar to a human eye—but, unlike human eyes, it can regrow itself if injured or even amputated. New research from the Stowers Institute for Medical Research has established the apple snail as a novel research organism to study eye regeneration, with the potential to better understand and find treatments for eye conditions in humans like macular degeneration. The study, from the lab of Stowers President and Chief Scientific Officer Alejandro Sánchez Alvarado, Ph.D., published in Nature Communications on [date], describes a new system to study sensory organ ...

This snail’s eyes grow back: Could they help humans do the same?

Human eyes are complex and irreparable, yet they are structurally like those of the freshwater apple snail, which can completely regenerate its eyes. Alice Accorsi, assistant professor of molecular and cellular biology at the University of California, Davis, studies how these snails regrow their eyes — with the goal of eventually helping to restore vision in people with eye injuries. In a new study published Aug. 6 in Nature Communications, Accorsi shows that apple snail and human eyes share many anatomical and genetic features. “Apple snails are an extraordinary organism,” said Accorsi. “They provide a unique opportunity to study regeneration of complex ...

New European toolkit launched by EU agencies to help eliminate viral hepatitis B and C in prisons

The new toolkit is designed to support the implementation and scale-up of hepatitis B and C interventions in prisons across Europe. It also reinforces the principle of ‘equivalence of care’, ensuring that people in prison receive healthcare comparable to that available in the community. People in prison experience higher levels of viral hepatitis than the general population, making them a key group for targeted prevention and treatment. In Europe, individuals entering prison are also more likely to have a history of injecting ...

Could the timing of food assistance payments affect crime rates?

Based on more than a decade’s worth of data across 36 U.S. states, a study in Contemporary Economic Policy finds that spreading out food assistance payments over more days reduces financially motivated crimes—especially robberies. Compared with a single-day lump-sum monthly distribution through the Supplemental Nutrition Assistance Program (SNAP), a disbursement schedule consisting of 15 or more distribution days was associated with a decline of 0.03 robbery incidents per 100,000 population. Similarly, when SNAP distribution was staggered across 15 or more days, the incidence of robbery ...

Predicting respiratory disorder mortality in dogs

Respiratory disorders in dogs can quickly become critical and are reported to be the second leading cause of cardiac arrest in canines. Therefore, it is necessary to take appropriate measures according to each patient’s condition. This, however, requires rapid and accurate disease severity assessments. In human medicine, scoring systems that incorporate physical examinations and blood tests results with respiratory function assessments exist, and enable more accurate severity assessments. In contrast, there are only a few reports on severity assessments that use tests other than respiratory function evaluations in veterinary medicine. Further, these evaluations usability ...

On-board camera footage offers bird’s eye glimpse into seabird flights and feeding behaviour

Scientists have captured unique on-board footage of Indian Ocean seabirds speeding just above the waves to catch flying fish on the wing. The footage, obtained by lightweight bird-borne cameras formed part of a study of the lives of seabirds in the waters around the remote archipelago they call home. Two red-footed boobies - a tropical cousin of the more familiar gannet – were carefully fitted with the tiny cameras to record how they catch their favourite food; flying fish. Of 15 capture attempts, 14 were towards flying fish while in flight and one was an underwater dive. This is the first such on-board footage revealing that flying ...

Why birds on the edge stay there: Study sheds light on murmuration mysteries

They twist and turn across the sky in dense, whirling formations—murmurations of birds that seem to move as one, captivating watchers and puzzling scientists for decades. Now, a new analysis suggests that one of the most mysterious features of these aerial displays—the behaviour of birds at the edges—may stem from accident rather than intent. A study examining the flocking patterns of jackdaws has found that the sharp borders of murmurations, and the way certain birds linger at the edges, can be explained by the mathematical rules that govern how individuals ...

There’s something fishy going on with great white sharks that scientists can’t explain

Key points White sharks exhibit stark differences between the DNA in their nuclei and the DNA in their mitochondria. Until now, scientists have pointed to the migration patterns of great whites to explain these differences. Scientists tested this theory in a new study by analyzing genetic differences between global white shark populations. In doing so, they discovered that great whites were restricted to a single population in the Indo-Pacific Ocean at the end of the last ice age 10,000 years ago and have since expanded to their current global distribution. The results also invalidate the migration theory, but an alternative explanation remains elusive. White sharks (Carcharodon carcharias) ...

Like us, pregnant roaches need more sleep

It might be humbling to consider, but cockroaches and people have more in common than we knew. Biologists at the University of Cincinnati discovered that some cockroaches, like people, need more sleep when they’re pregnant. And baby cockroaches need the mom to sleep longer for proper development. The study was published in the Journal of Experimental Biology. “A lot of us take adequate sleep for granted because we don’t usually experience an immediate adverse effect of sleep deprivation,” said study co-author Oluwaseun Ajayi, a postdoctoral researcher in UC’s College of Arts and Sciences. “The truth is the health consequences ...
