Females of some whale species have evolved to live drastically longer lives so they can care for their families, new research shows.

Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.

Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.

Recreating the action of opening doors in the virtual world requires engineering ways in which to provide the equivalent haptic feedback and steer users away from walls in the real world. A research group has done just this; developing RedirectedDoors+, which employs door robots and rotation to create a more realistic experience.

A new tool will help orthodontists correctly fit braces onto teeth. Using artificial intelligence and virtual patients, the tool predicts how teeth will move, so as to ensure that braces are neither too loose nor too tight.

Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.

Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.

Researchers used AI to scour information from websites and social media to map bat hunting and trade. Research found evidence of bat exploitation in 22 countries that had not previously been identified by traditional academic research. Following concerns about the reliability of the IUCN Red List, new research demonstrates how AI's ability to filter vast amounts of online data can support wildlife conservation.

A large find of dinosaur tracks and fossilized plants and tree stumps in far northwestern Alaska provides new information about the climate and movement of animals near the time when they began traveling between the Asian and North American continents roughly 100 million years ago.

The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers have found.

New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.

A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.

Obesity, which could reach 50% of the population in certain developed countries by 2030, is a major public health concern. It not only affects the health of those who suffer from it, but could also have serious consequences for their offspring. Scientists have studied the impact of maternal obesity on the risk of developing liver disease and liver cancer. Using an animal model, the team discovered that this risk was indeed much higher in the offspring of mothers suffering from obesity.

A new study has answered a long-held question about why medium-sized land animals like cheetahs tend to be fastest.

While most small insects and mammals urinate in droplets, cicadas urinate in jets. Researchers say the finding could be used to create better robots and small nozzles.

Scientists have discovered the specific enzyme that a species of sandfly uses to produce a pheromone attractant, which could lead to the creation of targeted traps to control them and reduce the spread of the potentially fatal disease, Leishmaniasis.

Researchers have developed a haptic device capable of reproducing the softness of various materials, from a marshmallow to a beating heart, overcoming a deceptively complex challenge that has previously eluded roboticists.

Grand-offspring of male frogs exposed to the pesticide linuron exhibited changes in their DNA that was linked to significant physiological impacts, a study reveals. The research highlights the profound transgenerational consequences of environmental pollution on amphibian populations, which are already under threat of extinction.

Researchers have painstakingly taken computed topography (CT) scans of more than 13,000 individual specimens to create 3D images of more than half of all the world's animal groups, including mammals, fishes, amphibians and reptiles.
