It is imperative for the success of the grape industry to develop new grape varieties capable of enduring shifting climates and heightened pressures from diseases and insects. The majority of grape cultivars rely on a specific amount of "chilling hours"' to complete dormancy for optimal growth and yield.

Kelp spores are being seeded and grown on small rocks and scallop shells—a seafood waste product—in efforts to regenerate the UK's coastal kelp forests.

A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered, and possibly one of the most dark matter-dominated systems known.

University at Albany researchers at the RNA Institute have developed a new method to test COVID-19 vaccine integrity that could allow anyone with basic skills in vaccine handling to detect expired vaccines quickly and effectively, without specialized lab equipment.

NASA's Europa Clipper spacecraft, headed to Jupiter's ice-covered moon Europa in October 2024, will carry a laser-etched message that celebrates humanity's connection to water. The message pays homage to past NASA missions that carried similar messages.

In research published in the journal Science experts addressed setting standards for three key indoor pollutants—carbon dioxide (CO2), carbon monoxide (CO), PM2.5, which are particles so small they can lodge deep in the lungs and enter the bloodstream—and ventilation rate. The paper is titled "Mandating indoor air quality standards for public,"

Vaccination not only reduces the severity of TB in infected cattle, but reduces its spread in dairy herds by 89%, research finds. The research, led by the University of Cambridge and Penn State University, improves prospects for the elimination and control of bovine tuberculosis (TB), an infectious disease of cattle that results in large economic costs and health impacts across the world. The study is published in the journal Science.

Every day, our cells are hard at work multiplying. Cell division is a precise process, but sometimes this process is impaired and diseases like cancer occur. Mitosis is one of the most important phases in the cell cycle. During this phase, a cell's DNA is split into two equal sets of chromosomes and it divides into two genetically identical daughter cells.

The nematode worm C. elegans will stay away from dangerous bacteria in its environment when exposed to certain bacterial RNAs—and can transmit that learned behavior to future generations. A team led by Coleen Murphy at Princeton University report these findings in a new study, published in the journal PLOS Genetics.

The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada.

All plants mediate their environmental interactions via chemical signals. An example is the alkaloid gramine produced by barley, one of the world's most widely-grown cereals. Gramine provides protection against herbivorous insects and grazing animals and inhibits the growth of other plants. Despite long-standing interest, the key gene for the formation of gramine remained elusive.

A global group of scientists has predicted that climate change may cause dramatic movements in venomous snake populations across many countries in Africa. The scientists took into account climate change predictions about changes to the current habitats of 209 venomous snakes, and mapped where those environments were found elsewhere. Based on this, they predict that snakes were likely to migrate to those African countries whose environments remained suitable for snakes after 2070. This could modify the dynamics of snakebites across Africa.

A new study, led by Carbon Mapper scientists alongside researchers from NASA Jet Propulsion Laboratory, Arizona State University, University of Arizona, Scientific Aviation, and the U.S. Environmental Protection Agency, provides the largest comprehensive assessment of hundreds of U.S. landfills using direct observations through airborne surveys.

According to the study, people aged 18–30 have the most negative attitudes towards adulthood, which could be due to them spending their early adult years struggling to "get ahead" amid the challenges of a pandemic and cost of living crisis.

When you think about a red object, you might picture a red carpet, or the massive ruby in the Queen's crown. Indeed, Western monarchies and marketing from brands such as Christian Louboutin have cemented our association of the color red with power and wealth.

An increasing number of places of worship are offering same-sex weddings, a decade on from same-sex marriage in England and Wales becoming legal, a new study shows.

Non-native species introduced mainly via increasing trade of goods and services have huge economic, health, and environmental costs. These "biological invasions" involve the intentional or unintentional transport and release of species beyond their native biogeographical ranges, facilitating their potential spread.

The UK will be increasingly tested by more droughts like 2022, emphasizing the importance of being prepared for similar extreme weather in future, say scientists who have analyzed that summer's events.

In the dark, early morning sky of March 21 over NASA's Wallops Island Flight Facility on the Virginia coast, a Rocket Lab Electron rocket carried a National Reconnaissance Office (NRO) manifest featuring three collaborative research missions into low-Earth orbit—including the latest piece of home-grown space hardware from the Naval Postgraduate School (NPS).

While the marshes may have meant danger for Pip in "Great Expectations," these wetland habitats are important wildlife havens and mitigate climate change.

Many policies and international frameworks—including the UN Sustainable Development Goals—recognize the need to end destructive fishing practices to conserve marine resources, protect the ocean and ensure peace and prosperity for people and the planet.

Having two autoimmune diseases is unusual for a dog, but having three is exceptionally rare.

A nasty quarrel arose in the 11th century over what kind of bread should be used in holy communion.

An international subcommittee of geologists recently voted to reject a proposal to make the Anthropocene an official new geological epoch, defined by humanity's enormous impact on the planet. Assuming some protests do not overturn the ruling, it will now take another decade for the decision to be reviewed.

Marine Protected Areas (MPAs) have been used as a conservation measure for decades, but critics continue to argue that evidence of their economic benefits is weak, particularly with regard to fisheries.
