Leaks from the Nord Stream gas pipelines released some 70,000 metric tons of the powerful greenhouse gas methane, researchers said Wednesday, less than previously thought.

"Fixed-duration" strikes—such as the three-day walkout by 15,000 nurses in mid-September—protect worker interests and impose financial and reputational costs on employers, suggesting that confrontational tactics can help unions counteract increasing employer power, according to new Cornell University ILR School research.

Climate change is driving more volatile precipitation patterns around the world—very dry stretches punctuated by storms that drop large amounts of rain or snow in a short amount of time. While wetter and drier spells may have certain effects that are easy to predict, such as on water levels in lakes and rivers, a recent study focused on California reveals that they can affect slow-moving...

Observations from the spacecraft's pass of the moon provided the first close-up in over two decades of this ocean world, resulting in remarkable imagery and unique science.

Drought that stretched across three continents this summer—drying out large parts of Europe, the United States and China—was made 20 times more likely by climate change, according to a new study.

Some solid materials have a memory of how they have previously been stretched out, which impacts how they respond to these kinds of deformations in the future. A new Penn State study lends insight into memory formation in the foams and emulsions common in food products and pharmaceuticals and provides a new method to erase this memory, which could guide how materials are prepared for future use.

The Earth System Grid Federation, a multi-agency initiative that gathers and distributes data for top-tier projections of the Earth's climate, is preparing a series of upgrades that will make using the data easier and faster while improving how the information is curated.

The complexity of life on Earth was derived from simplicity: From the first protocells to the growth of any organism, individual cells aggregate into basic clumps and then form more complex structures. The earliest cells lacked complicated biochemical machinery; to evolve into multicellular organisms, simple mechanisms were necessary to produce chemical signals that prompted the cells to both move...

Two renewable resources—cellulose from wood pulp and chitin from the shells of crabs, lobsters and other crustaceans—are known to industrial chemists for their potential for creating highly versatile nanocrystals, useful for making pharmaceuticals, cosmetics, industrial additives and much more.

In 2019, Boston University School of Public Health (BUSPH) eliminated the Graduate Record Examination as a requirement for admission to the school's graduate programs for a pilot period of three years.

A group of researchers led by Cornell is unlocking the full potential of aluminum nitride—an important material for the advancement of electronics and photonics—thanks to the development of a surface cleaning technique that enables high-quality production.

Over a 50-year period, logging on British Columbia's Central Coast preferentially targeted the highest value locations on the landscape, according to new research from Simon Fraser University. The systematic depletion of high-value components of the environment raises concerns about future sustainability and intergenerational access to natural resources.

Thanks to new RNA vaccines, we humans have been able to protect ourselves incredibly quickly from new viruses like SARS-CoV-2, the virus that causes COVID-19. These vaccines insert a piece of ephemeral genetic material into the body's cells, which then read its code and churn out a specific protein—in this case, telltale "spikes" that stud the outside of the coronavirus—priming the immune...

An application developed in collaboration with vulnerable communities to transmit early warnings of the risk of floods and environmental disasters has become public policy in Brazil, and the methodology is being replicated for use elsewhere. With practical results obtained in 2022, part of the discussions involving proposals to improve flood risk governance began at least two years ago.

Carnegie Mellon University researchers have pioneered the CMU Array—a new type of microelectrode array for brain computer interface platforms. It holds the potential to transform how doctors are able to treat neurological disorders.

Developing tools for precise control of biological processes has been one of the main pillars of the now mature field of synthetic biology. These scientific tools borrow principles from a multitude of research fields which, when combined, enable unique applications that are potentially transformative for the modern society.

In June of 2020, Stephen Gosser, a self-described "diehard birder," was out in the woods of Western Pennsylvania when he thought he heard the song of the elusive and strikingly beautiful scarlet tanager. The blood-red bird with black wings and tail is a favorite among birders for both its beauty and rarity, as the birds prefer to stay hidden high in the forest canopy.

Trying to understand people we disagree with can feel like an effort hardly worth making, particularly in contentious political environments in which offering even the smallest olive branch to the opposition can be perceived as betraying our own side. Research in Psychological Science, however, suggests that cross-partisan empathy may actually make our political arguments more persuasive, rather...

October is inarguably pumpkin season, which raises questions about food safety for everything from pumpkin pie to pumpkin seeds.

New research from marine scientists raises potential red flags for sharks that are caught and released by recreational anglers. The team has discovered that the ocean's iconic predators typically spike in temperature after they have been caught, which may have physiological and behavioral impacts.

A study by MBARI researchers and their collaborators published today in Ecology Letters sheds new light on the movements of mysterious, endangered blue whales. The research team used a directional hydrophone on MBARI's underwater observatory, integrated with other advanced technologies, to listen for the booming vocalizations of blue whales. They used these sounds to track the movements of blue...

Soil and its macrofauna are an integral part of many ecosystems, playing an important role in decomposition and nutrient recycling. However, soil biodiversity remains understudied globally. To help fill this gap and reveal the diversity of soil fauna in Hong Kong, a team of scientists from The Chinese University of Hong Kong initiated a citizen science project involving universities,...

A proposal to cover Arctic sea ice with layers of tiny hollow glass spheres about the thickness of one human hair would actually accelerate sea-ice loss and warm the climate rather than creating thick ice and lowering the temperature as proponents claim, according to a new study.

Chris Taylor, director of the beverage management program in the University of Houston Conrad N. Hilton College of Global Hospitality Leadership, watched in awe as sales of White Claw skyrocketed seemingly overnight in the summer of 2019.
