Methane is the second-largest contributor to climate warming after carbon dioxide, and so scientists have put a lot of attention toward addressing one of the top sources: methane emissions from livestock. In other words, cow burps are bad for the planet. Farmers add various seaweeds to cow diets as a source of protein, unsaturated fats, and other health-promoting ingredients that provide immediate energy, says Dipti Pitta of the University of Pennsylvania School of Veterinary Medicine, and a 2016 study in Australia found that feeding sheep a species ...

Native trees adapt to the climate and environmental conditions of their area to survive.

Traditional epidemiological studies have identified numerous potential risk factors, but observational studies have struggled to establish causal links due to confounding factors and reverse causation. Theoretically avoiding confounding and reverse causation, Mendelian randomization (MR) infers causality, offering novel research perspectives and methods for investigating risk factors of intestinal diseases (Figure 1). MR research on intestinal disease Based on MR methodology, researchers have identified lifestyle factors, circulating nutrients, and obesity as being associated with the risk of ...

Among the vastly different ways of tackling a disease, controlling the genetic expression of cells is undoubtedly one of the most powerful. Over the past few decades, scientists have come up with dozens of innovative strategies that involve using messenger RNA (mRNA) to ‘force’ cells to build specific proteins. These mRNA-based therapies have recently gained prominence as vaccines against infectious diseases like COVID-19. Additionally, they hold significant potential for treating cancer and genetic disorders. Since mRNA itself is ...

When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee “conversations” have found that they communicate back and forth using gestures following the same rapid-fire pattern. The findings are reported on July 22 in the journal Current Biology. “While human languages are incredibly diverse, a hallmark we all share is that our conversations are structured with fast-paced turns of just 200 milliseconds on average,” ...

An international team of researchers, including a Northwestern University chemist, has discovered that metallic minerals on the deep-ocean floor produce oxygen — 13,000 feet below the surface. The surprising discovery challenges long-held assumptions that only photosynthetic organisms, such as plants and algae, generate Earth’s oxygen. But the new finding shows there might be another way. It appears oxygen also can be produced at the seafloor — where no light can penetrate — to support the oxygen-breathing (aerobic) sea life living in complete darkness. The ...

Precision medicine aims to tailor treatments to individual patients to get the best possible outcomes. It does this by considering many different factors specific to the patient, such as the patient’s genetics, environment, lifestyle and more. But until now there have been no standardized guidelines for reporting precision ...

Research Highlights: Two new, basic research studies in rodents (mice and rats) analyzed the impacts that alcohol may have on the heart. In a mouse study, abnormal heart rhythms that can occur after a pattern of repeated simulation of binge drinking may be related to a spike in a stress protein found in the heart. Researchers tested a heart protective molecule to reduce the stress protein spike and the resulting irregular heart rhythms. In a study using rats that lacked estrogen production to simulate human menopause, alcohol exposure resulted ...

Soft rehabilitation gloves have become popular tools for helping patients with hand function-related disabilities recover finger movement. These gloves often use soft pneumatic actuators that employ air pressure to generate movements. Despite significant design improvements in recent years, many available soft actuators have drawbacks in achieving bidirectional motion typical of finger joints—such soft actuators facilitate finger bending (or flexion) but not finger straightening (or extension).   A group of biomedical researchers from Chiba University successfully ...

The bull elephants gather in the evening coolness to drink. After a spell, a senior male lifts his head and turns from the waterhole. With ears flapping gently, he lets out a deep, resonant rumble.  One by one, the others respond, their voices overlapping in a sonorous, infrasonic chorus that whispers across the savanna. This elephant barbershop quartet conveys a clear message: It’s time to move on. Gradually, the elephants shift, their massive bodies swaying as they follow their rumbling leader to the next stop on their nocturnal wanderings. For the first time, scientists from Stanford University and other institutions have documented male elephants using “let’s ...

Submarine canyons are crucial for the instability of the Antarctic ice sheet Antarctic canyons play a crucial role in the instability of the East Antarctic Ice Sheet, as they facilitate the transfer of relatively warm water (Circumpolar Deep Water) from the abyssal areas to the continental shelf and from there to the base of the ice sheet, thus contributing to its melting.  The new study, conducted by an international team of researchers led by the National Institute of Oceanography and Applied Geophysics (OGS) and including the University of Southampton, ...
