Cichlid fishes exhibit differing degrees of curiosity. The cause for this lies in their genes, as reported by researchers from the University of Basel in the journal Science. This trait influences the cichlids' ability to adapt to new habitats.

Scientists have called for a concerted global effort to stem the tide of disposable electronic technologies—such as vapes—contributing to international waste accumulation and environmental degradation.

In a landmark study based on one of the most comprehensive genomic datasets ever assembled, a team led by scientists at the University of Wisconsin–Madison and Vanderbilt University offer a possible answer to one of the oldest questions about evolution: why some species are generalists and others specialists.

For most human proteins, there are no small molecules known to bind them chemically (so-called "ligands"). Ligands frequently represent important starting points for drug development but this knowledge gap critically hampers the development of novel medicines.

Different types of barley recruit distinct communities of soil microbes to grow around their roots by releasing a custom mix of sugars and other compounds, according to a new study led by Jacob Malone of the John Innes Center, UK, published in the open-access journal PLOS Biology.

Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper.

ESA's Hera asteroid mission for planetary defense will make a swingby of Mars next March, borrowing speed to help reach its target Didymos binary asteroid system.

As Lyme disease cases rise in the U.S., humans are not the only ones at risk. Veterinarians with the Virginia-Maryland College of Veterinary Medicine say dogs are increasingly vulnerable to this tick-borne illness.

PFAS, or forever chemicals, are widespread and more likely to be found in public water systems serving low-income communities and communities of color in New Jersey, according to new research from Northeastern University.

Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free-floating—or rogue—planet. The planet was discovered using gravitational microlensing where the planet passed in front of a star, distorting its light and revealing its presence.

Dog aggression is a condition that can hit home for pet owners, as it can be unsettling, stressful, and even dangerous, not only for the dog but also for other pets, family members, and strangers.

As the climate changes, animals are doing what they can to adapt. Researchers from UBC Okanagan—which includes partners from Biodiversity Pathways' Wildlife Science Center, the Alberta Biodiversity Monitoring Institute, the University of Alberta, and Environment and Climate Change Canada—wanted to evaluate why deer densities in the boreal forest are rapidly increasing.

A research team has reviewed the process of gel formation in fermented sausages, emphasizing the crucial role of myofibrillar proteins and the influence of lactic acid bacteria, temperature, and processing methods on gel properties.

A research team has demonstrated that gene-based breeding (GBB) offers a transformative approach to advancing plant and animal breeding, showing remarkable predictability, speed, and cost-effectiveness. The review highlights GBB's impact on improving crop and livestock genetics, while also laying the foundation for molecular precision agriculture and medicine.

A research team has provided an overview for understanding the genetic basis of ornamental and cold resistance traits in Mei (Prunus mume), a tree valued both for its ornamental and cultural significance in China.

A research team reviewed the physiological and morphological changes in cool-season turfgrasses under high temperature stress, alongside advances in molecular characterization of their temperature regulatory networks. They proposed methods to enhance the turfgrasses' heat tolerance and highlighted the challenges in researching heat tolerance mechanisms.

Most American workers are hired "at will": Employers owe their employees nothing in the relationship except earned wages, and employees are at liberty to quit at their option. As the rule is generally stated, either party may terminate the arrangement at any time for a good or bad reason, or none at all.

A research team has substantially enhanced the annotation of the sweetpotato genome "Taizhong 6," introducing a more comprehensive and detailed version, v1.0.a2. This update utilizes 12 Nanopore full-length RNA libraries and 190 Illumina RNA-seq libraries, resulting in the identification of 360 new genes, modification or addition of 31,771 gene models, and refined gene nomenclature.

Did you receive a mail-order package this week? Carriers in the U.S. shipped 64 packages for every American in 2022, so it's quite possible.

A research team developed Fourier transform infra-red (FTIR) spectroscopy-based partial least squares regression (PLSR) models to assess Cenchrus spp (buffel grass) accessions, discovering significant correlations between cell wall composition and digestibility metrics like neutral detergent fiber (NDF) and indigestible NDF (iNDF).

A new University of Alberta study helps define the most helpful breeding habitat for the least flycatcher, a species of bird in rapid decline. The findings are published in The Wilson Journal of Ornithology.

Who plans the agenda for vacations in your family? Who's the first to step up to care for mom and dad or grandma and grandpa? Who's the one organizing family holidays? Chances are if you have an older sister, it's her. And if she's the only one in your family doing this, she may have "eldest daughter syndrome."

The collapse of key ecosystems would severely harm the global economy, researchers have warned. Researchers from UCL's Institute for Innovation and Public Purpose (IIPP) and the Global Systems Institute at the University of Exeter reviewed the likely impacts of "ecosystem tipping points" such as the dieback of the Amazon rainforest, tropical peatland collapse and widespread die-off of coral reefs.

South African president Cyril Ramaphosa recently painted a rosy picture in which the country's youth—"democracy's children"—had enormous opportunities for advancement, all thanks to successive post-apartheid governments led by the African National Congress (ANC) that he leads.

Arctic riverbanks are typically resilient, thanks to the power of permafrost. This permanently frozen soil locks in sediment, leading to low erosion rates. But as Arctic river water warms due to climate change, some researchers worry that riverbanks in the region will thaw and crumble. This, in turn, could cause problems, including the release of stored soil carbon and damage to infrastructure near rivers.
