A gene that limits cellular damage could be the key to surviving prolonged cold exposure.

Cleaner wrasse check their body size before fights due to having their own mental representation

Medaka fish that lacked functional Hmgn2 genes were unable to distinguish between simple shapes, revealing a new function for the regulatory gene.

Feeder-free induced pluripotent stem cells hold hope in therapies for cats’ chronic kidney disease

Wild boars and red junglefowl gave rise to common pigs and chickens. These animals’ genes evolved to express themselves differently, leading to signatures of domestication — such as weaker bones and better viral resistance — in pigs and chickens, according to a research team based in Japan.

Study shows fish may use punishment to promote help from their offspring

Genetic analysis finds evidence suggesting that acoustic fat bodies in the heads of toothed whales were once the muscles and bone marrow of the jaw.

A marine biologist is inching closer to conquering science’s over 120-year pursuit to farm lobsters by letting these “dragons of the sea” get real weird.

Acoustic recordings of a colony of little auks reveal their nocturnal activities and offer valuable monitoring means for avian biology in the Arctic.

Scientists at Osaka Metropolitan University have developed an efficient, non-invasive, and pain-free method to generate canine-induced pluripotent stem cells (iPSCs). They identified six reprogramming genes that can boost canine iPSC generation by 120 times compared to conventional methods using fibroblasts. The iPSCs were created from urine-derived cells without the need for feeder cells, an impossible feat until now. Their findings are expected to advance regenerative medicine and genetic disease research in veterinary medicine.

Pair-bonded Java sparrows show enlarged eye rings to signal breeding readiness.

Acoels have been found to host a wide diversity of symbiotic, photosynthetic microalgae.

Parasitic infections in salmonid fish can increase or decrease their vulnerability to angling, depending on their body condition.

Lim Boo Liat (21 August 1926 – 11 July 2020), a leading authority in the conservation of Malaysia’s biological diversity, had his initial interest in the outdoors piqued by nature lessons in school.

Important, yet often neglected: Tadpoles play a critical role in the ecology of aquatic habitats. On 279 pages, a new book presents descriptions for 99 species from the southeast Asian island of Borneo, covering all species commonly found, as well as representatives of the more cryptic ones. LIB-scientist Alexander Haas and his team of international collaborators worked over 20 years on its completion and just released “A Guide to the Tadpoles of Borneo”.

Biologists from Hong Kong Baptist University (HKBU) have discovered in Hong Kong waters three new species of hard coral which have never been identified anywhere else in the world. The findings come shortly after their discovery of one new coral and two new nudibranch species, which was announced last year under their research project on coral health in Hong Kong.

Scientists have revealed the genetic structure and diversity, and inferred the population history, of the wild house mouse across Europe and Asia.

A study on puddle frogs suggests underestimated biodiversity in Southeast Asia.

An international team of researchers respond to criticisms on previous work that demonstrated Mirror Self-Recognition (MSR) in the cleaner fish Labroides dimidiatus, by 1) successfully repeating the mark test with a larger sample size, 2) showing the MSR behaviour to be the visual result of the mark not a physical response to it, and 3) showing that MSR-trained fish do not show aggression to spatially varied mirror images of themselves. Additionally, they further demonstrate potential self-awareness in L. dimidiatus by showing that they do not demonstrate MSR behaviour when visually presented with the mark on other fish and solidify the importance of ecologically relevant marks presented in previous work by showing MSR behaviour of L. dimidiatus with brown marks, meant to resemble a main food source of the fish, as opposed to no such behaviour in fish with green or blue marks.

Researchers from DGIST explore the role of symbiotic skin bacteria in wound healing for different fish species

Just as humans may leave their home five minutes early to avoid a talkative neighbor or depart work late to avoid a rude coworker, carnivorous mammals may go out of their way to avoid other species. But they’re not trying to navigate awkward social interactions; rather, they are negotiating space and resources for survival.

Võ Quý (31 December 1929 – 10 January 2017) was a Vietnamese ornithologist who studied the destruction of tropical forests and agricultural lands in Vietnam by Agent Orange, a herbicide used by the U.S. military during the Vietnam War.

Abnormally high levels of DNA methylation have been identified in dogs exposed to high levels of lead near a mining area in Kabwe, Zambia, by a team of scientists from Japan and Zambia.

A collaboration between Osaka City University and Setsunan University sheds light on the effect urbanization has on the flesh fly species Sarcophaga similis. Through a series of laboratory and in-field experiments, scientists show that an increase in nighttime illumination and temperature, two of the major characteristics of urbanization, can postpone S. similis hibernation anywhere from 3 weeks to a month.
