The summit of an underwater mountain, higher than Mount Kosciuszko, has been mapped for the first time by the Australian icebreaker Research and Supply Vessel (RSV) Nuyina.

Realizing the vision of culturing organs for use in life-saving transplantation procedures is still a long way off. However, the work of Prof. Jacob Hanna on stem cells is paving the way for this to become a reality.

A new study shows how cell membranes curve to create the "mouths" that allow the cells to consume things that surround them.

Natural evolution is a slow process that relies on the gradual accumulation of genetic mutations. In recent years, scientists have found ways to speed up the process on a small scale, allowing them to rapidly create new proteins and other molecules in their lab.

More hurricanes are likely to slam Connecticut and the region as the planet continues warming due to greenhouse gas emissions, according to a study led by Yale University researchers.

Nearly three months after an undersea pipeline spilled thousands of gallons of crude oil into the waters off Southern California, authorities have announced that coastal cleanup efforts are now complete.

Let's take a journey into the depths of the Earth, down through the crust and mantle nearly to the core. We'll use seismic waves to show the way, since they echo through the planet following an earthquake and reveal its internal structure like radar waves.

A tiger was shot dead at a Florida zoo after biting a cleaner who had put his arm through the fencing of its enclosure, law enforcement and local media said.

A joint research team led by Prof. Husi Letu from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) has developed a new dataset, East Asia-Pacific longwave/shortwave downward radiation at the surface data set (2016–2020), from the new generation geostationary satellite Himawari-8.

With the holiday season's soon ending, many retailers are preparing for consumer returns requesting either exchanges and/or refunds.

Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. The rings are associated with basic physical properties such as the transition from an outer region where ice can form where water can only exist as water vapor. The astronomers made use of a spread of simulation to explore different possibilities of inner planet evolution. Our solar system's inner regions are a rare... Читать дальше...

Orchid hunting conjures images from the 1800s—explorers in mud-spattered khaki, traipsing through impenetrable jungle, overloaded with equipment: jars, bottles, bags and boxes, a gun (to shoot down tree-top orchids) and a magnifying glass. Things have changed a bit since then. You don't need to sail halfway around the world—and all you need is a camera or smartphone.

Has your home recently been overrun by tiny gray moths, flapping erratically around your kitchen? Spotted some suspicious webs in a cereal box? You might be sharing your dried food with pantry moths (Plodia interpunctella).

The publishing of several articles that reveal the vulnerability of farmed fish to the anisakis parasite has prompted the research group in Marine Zoology of the University of Valencia to experimentally assess the infective susceptibility of fish. The results from the ANITEST project, which just ended, show that in the improbable case that the parasite reaches farms, fish are not very susceptible to being infected.

Newly discovered imprints on a Welsh beach have been described as dinosaur footprints. The trackway dates from the Triassic, over 200 million years ago, and offers a unique snapshot of a moment in time.

With over 2,050 known species, Begonia is one of the largest plant genera. Since most Begonias are small weeds, a Begonia taller than a human is a very unusual sight. However, the newly discovered Begonia gigantica is one of the few exceptions.

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team led by Dr. Wang Shuangqiang from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences discovered plasma lensing phenomenon in a black widow pulsar PSR J1720-0533.

Scientists from the Institute of Microbiology of the Chinese Academy of Sciences (IMCAS) recently reported a minimized synthetic carbon fixation cycle. The cycle only contains four biochemical reactions and is capable of condensing two molecules of carbon dioxide into one molecule of oxalate in each round. The study was published in ACS Catalysis.

Observations suggest a warming trend in the Arctic, and a cooling trend in Eurasia during the past several decades. Is there a cause-and-effect relationship in this pattern? The question has been hotly debated for quite a while.

A team of researchers affiliated with multiple institutions in the U.S., the Institute for Advanced Study in Toulouse, France and the Max Planck Institute for Evolutionary Anthropology in Germany has found evidence that suggests early humans gained an energy budget by increasing their rate of energy acquisition, not by taking advantage of adaptive strategies. In their paper published in the journal Science, they describe their study of energy expenditure versus energy intake in early humans.

Researchers from the University of Chicago and Fordham University have conducted a long-term monitoring of three ultraluminous X-ray sources (ULXs) in the spiral galaxy NGC 891. Results of the research, presented in a paper published December 22 on arXiv.org, provide more insights into the properties of these sources and could help us better understand the nature of the host galaxy.

India's tiger conservation body said 126 of the endangered big cats died in 2021, the highest toll since it began compiling data a decade ago.
