Yet the treatment of these animals as livestock can be harsh, especially during transport. New international research, led by Southern Cross University animal welfare expert Associate Professor Barbara Padalino and published in the journal Animals, shows that more humane camel transportation is possible by using food as an incentive in place of physical punishment.

The ability to detect viruses and other harmful pathogens is highly advantageous for animals, as it can guide their behavior and prevent them from illness, and—in severe cases—death. When it comes to species that live in organized groups, such as bees, ants and some other insects, it can be even more crucial, as it can prevent the spread of pathogens across entire colonies.

Chronic stress is already tough on your gut—but new research suggests late-night eating could make things even worse. Scientists analyzing thousands of people found that those under high stress who also ate a large portion of their calories after 9 p.m. were far more likely to suffer from constipation and diarrhea. The combination appears to hit the gut twice, not only disrupting digestion but also reducing the diversity of beneficial gut bacteria.

Short-term nutritional state can reshape T cell metabolism, with post-meal lipid metabolism enhancing T cell metabolic capacity, cytokine production, and persistence after activation. The study identifies triglyceride-rich chylomicrons as key drivers of this effect, suggesting nutritional timing may matter for immune monitoring, vaccination research, and cell-therapy manufacturing.

While the world is a big place, humans are making greater and greater demands on the same areas of land. "This means that, unless we use the same land to serve multiple needs and coordinate this effort through planning, it is unlikely that we will have enough land for conservation, food and energy," said Grace Wu, a professor in UC Santa Barbara's Environmental Studies Program.

Thus, lighting along riverbanks or streams can have far-reaching ecological consequences. These results are published in Functional Ecology.

This scoping review found that social supermarkets can offer a more dignified, choice-based way to access lower-cost food while also helping divert some surplus food from waste. However, the evidence suggests they work best as a complement to existing food support, not as a solution to the underlying causes of food insecurity or overproduction across the food system.

A Nature Medicine study found that healthy Australian adults were widely exposed to plastic-associated chemicals, with processed, packaged, and canned foods emerging as important modifiable contributors to urinary phthalate and bisphenol levels.

Gibraltar’s macaques have been observed engaging in geophagy, the consumption of soil and clay, in an apparent attempt to quell their nausea from eating fatty and salty foods offered by tourists

Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. Troops of macaques living on Gibraltar—the only free-ranging monkey population in Europe—have been scientifically observed for the first time regularly engaging in geophagy, the practice of intentionally ingesting soil. The work appears in Scientific Reports.

Rising stream temperatures may be weakening the foundation of river food webs by altering how carbon moves through these watery ecosystems. In a new study published in the journal Ecosphere, researchers from Northern Arizona University found that when water temperatures increase, microbes and aquatic insects process fallen leaves, twigs, and bark more rapidly, but a smaller fraction of that leaf litter supports their growth and a bigger fraction is released into the water and air as carbon dioxide.
