Researchers conducted a study to determine if replacing dietary fats from palm oil, soy and other agricultural crops with fats created synthetically in chemical or biological processes could help reduce climate change-causing greenhouse gases. The researchers' analysis finds a reduction in carbon emissions and other benefits, such the opening of agricultural lands to reforestation which benefits biodiversity and creates a carbon sink.

Research in mice shows that the anti-inflammatory properties of exercise may arise from immune cells mobilized to counter exercise-induced inflammation. Immune cells prevent muscle damage by lowering levels of interferon, a key driver of chronic inflammation, inflammatory diseases, and aging. Read more ›

There are many creatures on our planet with more advanced senses than humans. Turtles can sense Earth's magnetic field. Mantis shrimp can detect polarized light. Elephants can hear much lower frequencies than humans can. Butterflies can perceive a broader range of colors, including ultraviolet (UV) light. Read more ›

Past cold periods such as the Little Ice Age were associated with reduced strength of North Atlantic currents and increased surface salinity in the Caribbean. This was accompanied by disturbances in the distribution of salt to the north leading to longer, stronger cooling phases in the northern hemisphere. Read more ›

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall. Read more ›

Researchers in Germany and the USA have produced the first theoretical demonstration that the magnetic state of an atomically thin material, ?-RuCl3, can be controlled solely by placing it into an optical cavity. Crucially, the cavity vacuum fluctuations alone are sufficient to change the material's magnetic order from a zigzag antiferromagnet into a ferromagnet. Read more ›

Mass spectrometers are high-tech machines that play an important role in our society. They are highly sensitive analytical instruments that are indispensable in areas such as medical diagnostics, food quality control and the detection of hazardous chemical substances. A research group is working to modify mass spectrometers so that they can be used for a completely different purpose: the chemical synthesis of new molecules. Read more ›

A species of exotic tick arrived in Ohio in 2021 in such huge numbers that their feeding frenzy on a southeastern farm left three cattle dead of what researchers believe was severe blood loss. The scientists have reported on the state's first known established population of Asian longhorned ticks, and are now conducting research focused on monitoring and managing these pests. Read more ›

As the world warms and ice sheets melt, the ocean continually rises. The greater Boston area can expect to see between one and six feet of sea level rise by 2100, according to recent estimates. To find out what this rise might mean for freshwater supplies, a team of hydrogeologists developed an innovative new model that can not only predict saltwater intrusion over the next 75 years, but also pinpoint...

By comparing genomes of several cat species, the project has helped researchers understand why cat genomes tend to have fewer complex genetic variations (such as rearrangements of DNA segments) than other mammal groups, like primates. It also revealed new insights into which parts of cat DNA are most likely to evolve rapidly and how they play a role in species differentiation. Read more ›

Americans who have a tooth pulled or another painful dental procedure in the United States today are far less likely to get opioid painkillers than they were just a few years ago, a new study shows. But the COVID-19 pandemic seems to have thrown a wrench into the effort to reduce opioid use in dental care. Read more ›

A team of researchers has unveiled a first-of-its-kind stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device's heat movement. The group's study details how the device works and its potential applications. With top speed and performance, the transistor could open new frontiers in heat management of computer chips through an atomic-level design and molecular engineering. The advance could also further the understanding of... Read more ›

An international team of researchers has discovered that formaldehyde, a widely spread pollutant and common metabolite in our body, interferes in the epigenetic programming of the cell. This finding expands the knowledge of formaldehyde, previously considered only as a DNA mutagen, and helps establishing a further link with cancer. Read more ›
