Researchers from Newcastle University, UK have engineered Escherichia coli bacteria to capture carbon dioxide (CO2) using hydrogen gas (H2) to convert it into formic acid. The research, published today in Applied and Environmental Microbiology raises the possibility of converting atmospheric CO2 to commodity chemicals.

The diversity of human languages can be likened to branches on a tree. If you're reading this in English, you're on a branch that traces back to a common ancestor with Scots, which traces back to a more distant ancestor that split off into German and Dutch. Moving further in, there's the European branch that gave rise to Germanic; Celtic; Albanian; the Slavic languages; the Romance languages like Italian and Spanish; Armenian; Baltic; and Hellenic Greek. Before this branch, and some 5,000 years into human history... Читать дальше...

The eyes have it. They are constantly on the move when viewing scenes in augmented reality (AR).

h-index, g-index, i10 index, m-quotient, Journal Impact Factor, Altmetrics … it's long been an intractable issue plaguing the research community—how to assess the relative merits of research objectively across disciplines and make fair comparisons between early career and established researchers, different genders, and even different research disciplines.

Like a spider trapping its prey, our immune system cells cooperate to capture and "eat" bacteria.

Making eye contact repeatedly when you're talking to someone is common, but why do we do it? When two people are having a conversation, eye contact occurs during moments of "shared attention" when both people are engaged, with their pupils dilating in synchrony as a result, according to a Dartmouth study published in the Proceedings of the National Academy of Sciences.

A decades-long study of voles on the Norwegian archipelago of Svalbard is offering insights into a longstanding puzzle of Arctic ecology—effectively, what drives the well-established population cycles of small Arctic mammals, such as voles and lemmings.

Natural and manmade physical structures all lose energy, and scientists work hard to eliminate that loss or compensate for it. Optical and photonic devices lose energy through light scattering, radiation or material absorption. In some situations, however, intentionally yet carefully designing loss in open optical devices and systems can lead to unconventional physical phenomena which inspires novel methods for optical control and engineering.

The diet of the yellow-legged gull in the Medes Islands (Girona, Spain) has changed extremely over the last decades, according to a study that analyzes the changes in the diet of this species over the last twenty years. Regarding these gulls, which eat strictly marine resources, landfills and meat industries ̶ which are abundant in the area ̶ are nowadays the source for food of about 50% of their diet.

An Orland Park, Illinois, woman who raises butterflies in her home hit the monarch migration jackpot: A tiny tag affixed to one of her 2020 butterflies was recovered in the mountainous region of central Mexico where Midwestern migratory monarchs spend the winter.

Climate change scientists don't like to use the term "prediction." Rather, they're making "projections" about the future of the planet as sea levels rise, wildfires sweep the West and hurricanes become more ferocious.

To provide X-ray beams that are both very bright and very tightly focused, an Argonne team had to create a new system of mirrors, lenses and equipment for the upgraded Advanced Photon Source.

Global computing could be responsible for a greater share of greenhouse gas emissions than previously thought and these emissions will continue to rise significantly unless action is taken, a new study highlights.

Hurricane Olaf slammed into the Los Cabos resorts at the tip of Mexico's Baja California Peninsula and then drenched the region Friday with torrential rains as emergency workers evacuated people from flood-prone areas .

A study into the energy-making process in plants could help engineer crops more resistant to stress or bacteria that produce pharmaceuticals.

Hunter-gatherer populations with a strong seasonal dependence on meat in their diets had fewer people per square kilometer than those that had abundant plant foods throughout the year.

A research team from the Universitat Autònoma de Barcelona (UAB) has generated the first rat model recapitulating all disabling alterations experienced by patients with Mucopolysaccharidosis type IVA, also known as Morquio A disease. The team has developed a gene therapy that fully corrects the severe whole-body alterations in the rat model after a single intravenous viral vector administration. The research opens the door to a future therapy which could be administered at young ages in patients diagnosed with this rare disease... Читать дальше...

A new study from North Carolina State University suggests textbook wording that portrays climate change information as uncertain can influence how middle and high school students feel about the information, even for students who say they already know about climate change and its human causes.

Right now, there's just one virus on everyone's minds: SARS-CoV-2, the virus that causes COVID-19. But humanity is plagued by many respiratory viruses, such as influenza A (IAV) and respiratory syncytial viruses (RSV), which cause hundreds of thousands of deaths every year. Most of these viruses—apart from influenza and SARS-CoV-2—have no vaccines or effective treatments.

A group of united astronomers have successfully convinced Europe's leading astronomy journal Astronomy & Astrophysics to institute a name change policy for transgender people and others. "It's really frustrating that such a large organization needed an initiative from outside to adopt a more inclusive policy," says astronomer Emily Hunt.

Scientists say they've found the first evidence of tool use by a kea for the purpose of self-care, in a new study from the University of Auckland.

An international collaboration of scientists has taken a significant step toward the realization of a nearly "green" zero-net-carbon technology that will efficiently convert carbon dioxide, a major greenhouse gas, and hydrogen into ethanol, which is useful as a fuel and has many other chemical applications. The study reports a "roadmap" for successfully navigating this challenging reaction and provides a picture of the full reaction sequence using theoretical modeling and experimental characterization.

Global mean surface temperatures reached 1.2°C above the pre-industrial average in 2020, and the Intergovernmental Panel on Climate Change warned in its recent report that Earth could hit 1.5°C in as little as a decade. The 0.3°C separating these two temperatures make a world of difference. Scientists believe that stabilizing our warming world's temperature at 1.5°C could help avoid the most serious effects of climate change.

In a study published in Cell Stem Cell, the research group led by Dr. Zhou Bo from the Center for Excellence in Molecular Cell Science, Shanghai Institute of Biochemistry and Cell Biology of the Chinese Academy of Sciences reported the transition of skeletal progenitor during postnatal bone growth.

Nearly half of adults (44 percent) reported having experienced some kind of discrimination since the start of the pandemic, find UCL researchers as part of the COVID-19 Social Study.
