Addressing climate change is a massive and daunting challenge. But many economists say gradually increasing taxes on emissions would significantly reduce the amount of greenhouse gas spewed into the air at the lowest economic cost.

A study led by Simon Fraser University researchers has discovered that sufficient water flows during summer can be critical to a Chinook salmon population in the interior of British Columbia.

Gender bias in physics labs—where women typically work more on the computer and on communication tasks, while men more often handle equipment—is not rooted in personal preference, according to new Cornell research.

The sun emitted a mid-level solar flare on Jan. 20, 2022, peaking at 1:01 a.m. EST. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event.

In 2021, NASA technology saved 330 lives in the U.S. network region of the international satellite-aided search and rescue effort, Cospas-Sarsat. NASA has lent technical expertise to the Cospas-Sarsat program since its founding, aiding in the rescue of over 48,000 individuals globally.

Federal agents on Thursday returned two ancient stone artifacts to representatives of the Iraqi government at the country's consulate in Los Angeles.

State officials said Thursday they will increase deliveries to farms and cities that belong to the State Water Project—a sign that this winter's rain and snow has eased drought conditions in California.

In a win-win for commercial fisheries and marine wildlife, researchers have found that using lighted nets greatly reduced accidental bycatch of sharks, rays, sea turtles, and unwanted finfish.

Concerned about nightmarish traffic jams at Yosemite National Park from more than half a dozen major new construction projects, park leaders are drawing up plans that could limit the number of visitors this summer by requiring reservations for day visits.

Male and female mouse brains differ in important ways, according to a new study led by Stanford Medicine investigators.

Associate Professor Jonathan Boreyko and graduate fellow Mojtaba Edalatpour have made a discovery about the properties of water that could provide an exciting addendum to a phenomenon established over two centuries ago. The discovery also holds interesting possibilities for cooling devices and processes in industrial applications using only the basic properties of water. Their work was published on Jan. 21 in the journal Physical Review Fluids.

Demand for rhino horn in Asian markets, especially Vietnam and China, has pushed the remaining rhino populations to the brink of extinction. In the past decade, nearly 10,000 rhinos were killed by poachers in Africa. The remaining rhino populations in Africa and Asia are steadily declining, with fewer than 30,000 animals left in 2020 from a population of 500,000 at the beginning of the 20th century.

Rebooting a quantum computer is a tricky process that can damage its parts, but now two RIKEN physicists have proposed a fast and controllable way to hit reset.

Combining topological states of matter with strong electron correlation promises many exotic phenomena such as charge fractionalization, excitonic instability, and axionic excitation. Layered transition-metal pentatellurides ZrTe5 and HfTe5 were found to be close to an accidental topological semimetal phase with low carrier density. Even in a relatively low magnetic field, they can form highly degenerated Landau levels and dramatically enhance the correlation effect of Dirac electrons therein. Therefore... Читать дальше...

We have been living in a COVID-19 pandemic world for two years—and almost everything about our lives has been affected. Travel and holidays in particular have been constrained through border closures and lockdowns. It's too early to say what effect this may have on overseas travel long term. But one form of travel that is forecast to grow in popularity is pilgrimage.

A team of researchers affiliated with several entities across Australia has found that in order to save the world's coral reefs, conservationists must also protect the corridors that connect them. In their paper published in the journal Science, the group describes their study of coral and fish larval sources and sinks and the dispersal corridors promote health and diversity in coral reefs.

A study of electron dynamics timed to millionths of a billionth of a second reveals the damage radiation can do on a molecular level.

Bumblebees are important pollinators because they pollinate many different plant species and are extremely resilient. They can still manage to fly at temperatures that are too cold for other pollinators. Like many other insects, they are in sharp decline. This makes it even more important to find out what bumblebees need to reproduce successfully. A team from the University of Göttingen has shown that a diverse landscape and a diverse pollen diet, which the bumblebees collect as a protein source to nourish their offspring... Читать дальше...

Researchers at the University of Helsinki have developed a new, faster and more reliable technique for reverting human cells to the stem cell state. Pluripotent stem cells are a key tool in biomedicine for modeling various diseases and developing novel therapies.

It's no accident that both the Massachusetts Institute of Technology and the California Institute of Technology claim the beaver (Castor canadensis) as their mascots. Renowned engineers, beavers seem able to dam any stream, building structures with logs and mud that can flood large areas.

As vaccination rates continue to rise and government border policies change, the need for hotel quarantine is fading.

Though they may be small, microorganisms are the most abundant form of life in the ocean. Marine microbes are responsible for making roughly half of the organic carbon that's usable by life. Many marine microbes live near the surface, depending on energy from the sun for photosynthesis.

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless combinations before cooling and settling into more stable configurations to make the neutrons and protons of ordinary matter.

The catalog of planet candidates found with NASA's Transiting Exoplanet Survey Satellite (TESS) recently passed 5,000 TOIs, or TESS Objects of Interest.

When baking a cake, even a small change to your recipe can have a major impact on the final product. Recently, researchers in Japan have demonstrated that a small alteration in the gene expression "recipe" of the model organism Ciona intestinalis leads to a significant change in the development of sensory cells.
