This image taken by the NASA/ESA Hubble Space Telescope revisits the Veil Nebula, which was featured in a previous Hubble image release. In this image, new processing techniques have been applied, bringing out fine details of the nebula's delicate threads and filaments of ionized gas.

The directly catalytic oxidation of alkanes has high atomic economy and application value to form corresponding chemical organic products such as alcohols, aldehydes, ketones and carboxylic acid. It is challenging to achieve efficient and selective oxidation of alkanes under mild conditions due to the inert C-H bonds of alkanes.

As an essential material for the survival and reproduction of almost all aerobic organisms, oxygen is closely related to the formation and development of complex organisms. A recent review provides a systematic overview of the latest advances in the oxygen cycle at different spatial and temporal scales and the important role that oxygen plays in shaping our current habitable Earth.

Across California's Central Valley, under stress from large-scale agriculture and climate change, native bee species that are flexible in their pollination behavior when around other wild bee populations appear best suited for survival in shrinking habitats.

With its belching smokestacks, Bulgaria's Bobov Dol coal plant symbolises the type of industry the EU aims to eliminate—and the hurdles it faces in its green transition.

Proteins are large, highly complex and naturally occurring molecules can be found in all living organisms. These unique substances, which consist of amino acids joined together by peptide bonds to form long chains, can have a variety of functions and properties.

ESA's M-Argo mission will be the first CubeSat to traverse interplanetary space under its own power. Due to launch in 2024-5, the suitcase-sized spacecraft will travel to a near-Earth asteroid, up to 150 million km away.

A new book published today explains how the famous mummy Takabuti was likely to have been murdered over 2,600 years ago.

Andrew Whiten, an evolutionary and developmental psychologist with the University of St. Andrews in the U.K., has published a Review piece in the journal Science giving an overview of evidence for culture in many species of animals, including insects and fish. In his paper, he notes that the long-held notion that only humans have culture has long been dispelled.

In a September 2020 essay in Nature Energy, three scientists posed several "grand challenges"—one of which was to find suitable materials for thermal energy storage devices that could be used in concert with solar energy systems. Fortuitously, Mingda Li—the Norman C. Rasmussen Assistant Professor of Nuclear Science and Engineering at MIT, who heads the department's Quantum Matter Group—was already thinking along similar lines. In fact, Li and nine collaborators (from MIT, Lawrence Berkeley National Laboratory... Читать дальше...

Just over half of teaching assistants in schools stepped-up to manage classes on their own during the winter lockdown ensuring vulnerable and key worker children could attend lessons, according to a new study by UCL researchers.

Quillon Simpson, a postdoctoral research associate at Northeastern, spotted the tiny black-and-white border collie pup from clear across the country via video during the pandemic last August and instantly knew she was the pooch for him.

The pandemic has been bad for business, but it hasn't necessarily been bad for U.S. state tax revenues; in fact, 22 states saw tax revenues increase during 2020. These outcomes ran counter to estimates made during the year, but a new analysis from researchers at NC State and the University of Texas at Dallas reveals one possible explanation.

Chemical reactions and physical processes that involve water surfaces will be easier to model thanks to the discovery by an all-RIKEN team of how the molecules at water surfaces lose energy.

The development of innovative magnetic nanodevices is one step closer to reality thanks to the observation by RIKEN physicists of a type of rotation that can be realized in materials consisting of light elements.

Polar bears are often considered the poster-child species for climate change impacts. With global warming and sea-ice declines, it becomes harder for polar bears to hunt their preferred prey—seals. Increased global temperatures are having the greatest impact on Arctic and Antarctic environments, with arctic polar bears projected to decline by 30 percent by 2050.
