Researchers at Forschungszentrum Jülich and the Berlin Institute of Health at Berlin's Charité Hospital have developed a novel method for determining the number of subunits within protein complexes. The method is a further development of "super-resolution" single molecule localization microscopy (SMLM), whose developers were awarded the Nobel Prize in Chemistry in 2014. The new technique allows researchers to analyze the composition of protein complexes in intact cells.

New details surrounding the dark cloud L1527 and its protostar have been revealed by NASA's James Webb Space Telescope. The nebula's vibrant colors, only visible in infrared light, show the protostar is in the midst of gathering material on its way to becoming a full-fledged star.

A new study by the dating app Match in partnership with Indiana University researchers shows that political issues are increasingly important to singles in the Midwest when it comes to considering potential partners. According to the study, 29% of Midwestern singles consider not having an opinion on a key political issue a dealbreaker—up from just 15% in 2017.

It starts with a fairly simple premise: A majority of people, no matter which side of the political aisle they occupy, believe that someone with a history of violence should not be able to have a gun. This common ground between gun owners and non-gun owners is the basis for a policy platform proposed in a report out today from Tufts University School of Medicine experts, who led research into the topic, and 97percent, a bipartisan organization of gun owners and non-gun owners committed to reducing gun deaths.

Researchers at the University of São Paulo's Center for Nuclear Energy in Agriculture (CENA-USP) in Brazil, collaborating with colleagues in Canada, France, Italy and Spain, reviewed 1,154 original scientific articles published between 2009 and 2022 on the effects of nanomaterials in 1,374 plants belonging to 253 species. The metadata review assembled and organized quantitative information on the experimental parameters used in the scientific literature of the past decade.

The nearshore rocky reefs of the Santa Barbara Channel are dynamic places, with populations of fish, mollusks, algae and other assorted sea life shifting in response to currents, storms and a variety of other conditions. They wax and wane, typically returning to some sort of baseline composition—a kind of standard demographic—after disturbances temporarily disrupt the neighborhood, and then subside.

Government agencies and public sector organizations face unique constraints that impede their ability to discover new innovations, according to new research from Binghamton University, State University of New York.

Researchers from University of Colorado Denver, California State University Long Beach, Texas A&M University, and Kansas State University published a new Journal of Marketing article that examines the role of innovation potential as a credible signal that reduces the adverse selection present in IPO deals with insider sales.

Scientists hope that the electricity generated by renewable energy can be used to convert CO2 into value-added fuels, and the stored energy in these chemicals can be released as electricity through fuel cells or other technologies. Such a practice can not only realize the storage of renewable energy, but also mitigate anthropogenic CO2 emission.

Is there life in Martian caves?

For research, plants are frequently grown under stable lighting, which does not reflect natural conditions. In a series of experiments with changing light conditions, simulating the natural interplay of light and shadow, researchers from the Max Planck Institute of Molecular Plant Physiology in Potsdam-Golm (Germany) and the College of Natural Science at Michigan State University (U.S.) reveal the importance of two key proteins for the dynamic control of photosynthesis. The study was recently published in the journal New Phytologist.

Negotiators from around 200 countries appeared to be struggling to reach consensus at the COP27 climate conference on Tuesday, with disagreement on the phaseout of fossil fuels and the 1.5 degrees Celsius warming mark.

When polar seas freeze and ice forms, it is not only due to cold air chilling the surface of the water. Even more important is that warm water is prevented from rising to the surface from the depths of the ocean, due to the much lower salinity of the surface water. Researchers from the University of Gothenburg and elsewhere have described this effect in a new scientific study.

Ending a requirement that has been in place for the past three years, Yosemite National Park won't require people to make reservations next year for day visits to the famed Sierra landmark.

The Earth's climate has undergone some big changes, from global volcanism to planet-cooling ice ages and dramatic shifts in solar radiation. And yet life, for the last 3.7 billion years, has kept on beating.

Female putty-nosed monkeys deliberately use alarm calls to recruit males to defend the group. This is the conclusion reached by Claudia Stephan, an evolutionary biologist at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), together with colleagues from the Wildlife Conservation Society after conducting observations in the Republic of the Congo.

A new report by UNICEF, supported by University of Southampton researchers, says 559 million children currently exposed to high heat waves could rise to 2.02 billion globally by the year 2050.

What will happen to our sun?

International climate talks in Egypt known as COP27 are into their second week. Thursday is Solutions Day at the summit. Recognizing that urban planning is now a front-line response to climate change, discussions will focus on sustainable cities and transport, green buildings and resilient infrastructure.

Tap water in more than 500 remote Indigenous communities isn't regularly tested and often isn't safe to drink, according to a water industry report released last week. In some communities, drinking water contained unacceptable levels of uranium, arsenic, fluoride and nitrate.

A couple of weeks before her short stint as prime minister ended, Liz Truss delivered on a pledge to tackle what some—including Truss—saw as red tape holding back "thousands of growing businesses" in the UK. The move focused on exempting small businesses from certain regulations to help stimulate growth. It involved expanding the government's definition of "small business" to release "thousands of UK businesses" from reporting requirements and regulations.

Since 2008, Australia has spent more than A$11 billion dollars over ten years to expand government-funded preschool (or kinder in Victoria) for four-year-olds to better prepare children for school.

It couldn't have been a case of better timing. Egyptologists celebrating the centenary of the discovery of the tomb of Tutankhamun, now have a promising new archaeological discovery that appears to have been made in Egypt. Excavators have discovered a tunnel under the Taposiris Magna temple, west of the ancient city of Alexandria, which they have suggested could lead to the tomb of Queen Cleopatra. Evidence that this is really the case remains to be seen, but such a discovery would be a major find... Читать дальше...

The world population has just hit a new record: 8 billion. As is often the case, there are heated debates about the planet's so-called "carrying capacity"—the total number of people who can live on Earth sustainably. Experts are generally divided into two camps. There are those who argue that we need to drastically reduce the human population to avoid ecological catastrophe. And then there are those who believe that technology will find smart solutions without any need to actively tackle the issue head-on.

NASA's Artemis I launch is a major step forward in humans going deeper and spending longer in space than ever before.
