Carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by researchers in academia.

Researchers have unveiled evidence for ancient human resilience to climate change in the Eastern Mediterranean.

The inventors of a suite of tests that enable food packages to signal if their contents are contaminated are working to bring producers and regulators together to get their inventions into commercial products, with the goal of preventing illness and reducing food waste.

As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.

Evapotranspiration (ET) includes evaporation from soil and open water pools such as lakes, rivers, and ponds, as well as transpiration from plant leaves. The difference between precipitation and ET indicates the water balance available for societal needs, including agricultural and industrial production. However, measuring ET is challenging. A new study presents a computer model that uses artificial intelligence (AI) for ET prediction based on remote sensing estimates.

The link between massive flood basalt volcanism and the end-Triassic (201 million years ago) mass-extinction is commonly accepted. However, exactly how volcanism led to the collapse of ecosystems and the extinction of entire families of organisms is difficult to establish. Extreme climate change from the release of carbon dioxide, degradation of the ozone layer due to the injection of damaging chemicals, and the emissions of toxic pollutants, are all seen as contributing factors. One toxic element stands out: mercury.

A team of researchers has investigated the motivation and potential incentives for and challenges of low-intensity grazing among farmers and land users in Europe.

Researchers have developed a chemical process using plasma that could create sustainable jet fuel from methane gas emitted from landfills, potentially creating a low-carbon aviation industry.

A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United Nations for that year.

Scientists report significant progress in cultivating nephron progenitor cells (NPCs), the cells destined to form the kidney's filtration system, the nephrons. NPCs hold immense promise for understanding kidney development, modeling diseases, and discovering new treatments. The team improved the chemical cocktail for generating and growing NPCs in the laboratory, enabling the sustained growth of both mouse and human NPCs in a simple 2-dimensional format.

A new type of bioplastic could help reduce the plastic industry's environmental footprint. Researchers have developed a biodegradable form of thermoplastic polyurethane (TPU) filled with bacterial spores that, when exposed to nutrients present in compost, germinate and break down the material at the end of its life cycle.

A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.

The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.

Scientists have applied a dynamic model of the landscape to patterns of human migration into Sahul, the combined continent of Australia, Tasmania and New Guinea.

An estimated 168 billion gallons of wastewater -- or produced water -- is generated annually by the Permian Basin fracking industry, according to a 2022 report. The major waste stream has proved both difficult and costly to treat because of the chemical complexity of the water.

Researchers have discovered a new mechanism of oil biosynthesis and found a way to genetically engineer a type of test plant to more efficiently produce different kinds of seed oil that it otherwise wouldn't make. While the engineering is proof-of-concept, this discovery could lead to improved production of valuable oils used in food and by a range of industries. The modified plant overcame metabolic bottlenecks and produced significant amounts of an oil similar to castor oil that it doesn't naturally produce.

Researchers have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants). This sheds light on the complex actions that cause plant adaptation and ecological diversity.

After-care food and drink accounted for about 22% of the day's added sugar and about one-third of the sweet and salty snack foods the children ate, according to a new study.

Cranberry extracts appear to improve intestinal microbiota and help prevent chronic diseases such as diabetes and cardiovascular diseases. The study reported beneficial effects after only four days of use.

3D microscopes are used in applications from the life sciences to semiconductor manufacturing. Now engineers are developing patented and patent-pending innovations making them work faster to capture even more 3D images and less expensive to manufacture.
