A team of biologists from NYU and Harvard has identified new details in a cellular mechanism that serves as a defense against stress. The findings potentially offer insights into tumor progression and neurodegenerative diseases, such as Parkinson’s and Alzheimer’s—the cell’s inability to respond to stress is a major cause of these diseases.
Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. Scientists have known about the presence of ri…
A new study by Kansas State University veterinary diagnosticians finds that pets with out-of-date rabies vaccinations are very unlikely to develop the fatal disease if given a rabies booster immediately after exposure to the virus.
Leaving heavier Merino ewes untreated for worms while treating their skinnier counterparts may help combat drench-resistant worms, research suggests.
The value of a herd bull is determined not just by his genetic merit, but also by the number of calves he may or may not sire, according to a Texas A&M AgriLife Extension Service specialist.
Researchers have identified a population of “progenitor” cells in the skin that are solely responsible for the generation and maintenance of touch-sensing Merkel cells. The study appears in The Journal of Cell Biology.
US President Barack Obama said Sunday he would recommend a large swath of Alaska be designated as wilderness, the highest level of federal protection, in a move likely to anger oil proponents.
Ugandan wildlife officers have seized a huge haul of elephant ivory and pangolin scales, representing the deaths of hundreds of endangered animals, police said Sunday.
Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
Shortly before 11 am on the last Saturday in May, a heavily laden white Mitsubishi truck pulled into the Fuji Motors East Africa car dealership in an industrial neighbourhood on the northern edge of Mombasa.
From the pittance paid to local poachers to a multi-billion dollar industry, here are some of the key numbers related to Africa’s endangered elephants:
Pallid sturgeon come from a genetic line that has lived on this planet for tens of millions of years; yet it has been decades since anyone has documented any of the enormous fish successfully producing young that survive to adulthood in the upper Misso…
A camera can accurately count freshwater fish, even in the thickest of underwater vegetation, a key finding for those who manage fisheries and control the invasive plant hydrilla, new University of Florida research shows.
It has been assumed that the increased transmission of sexually-transmitted diseases in the case of mating promiscuity is influential in shaping the immune system of mammals. Results published in the scientific journal Functional Ecology this week demo…
Department of Fisheries staff and Kalbarri fishermen have released 24,000 Roe’s abalone (Haliotis roei) onto reef platforms along the cliffs north of Kalbarri, to restock a population decimated by the marine heat wave of 2010-11.
In literature, crows and ravens arebad omens and are associated with witches. Most people believe they steal, eat other birds’ eggs and reduce the populations of other birds. But a new study, which has brought together over 326 interactions between cor…
A light brown remains light brown: For gerbils, the fur color of their conspecifics appears identical under different lighting conditions. The ability of color constancy in rodents has been demonstrated for the first time by Munich neurobiologists.
The manner and routes of dispersal vary with the species and the ecological conditions. Many fish form shoals to avoid predation. Shoaling with familiar conspecifics affords the fish an even greater advantage by increasing the benefit for relatives. Th…
