A new study offers entrepreneurs some savvy sales advice: When pitching to investors for funding, a high-octane product pitch with great enthusiasm can be a double-edged sword.

A research team lead by scientists from the Max Planck Institute for Biology, Tübingen, Germany, has now made substantial progress in understanding how gut bacteria succeed in their human hosts on a molecular level. They investigated how bacteria produce inositol lipids, substances vital for many cellular processes in humans and other eukaryotes but hitherto rarely observed in bacteria. The results, now published in the journal Nature Microbiology, indicate that inositol lipids have implications... Читать дальше...

Society recognizes that many politicians lie. In five new studies, researchers have examined how conservative and liberal Americans responded to media reports of politicians' falsehoods. Even accounting for partisan biases in how much people dismissed the reports as fake news and assumed the lies were unintentional, the studies consistently identified partisan evaluations in how much these falsehoods were considered justifiable. The researchers' work—which also touches on issues of trustworthiness... Читать дальше...

To solve a long-standing puzzle about how long a neutron can "live" outside an atomic nucleus, physicists entertained a wild but testable theory positing the existence of a right-handed version of our left-handed universe. They designed a mind-bending experiment at the Department of Energy's Oak Ridge National Laboratory to try to detect a particle that has been speculated but not spotted. If found, the theorized "mirror neutron"—a dark-matter twin to the neutron—could explain a discrepancy between... Читать дальше...

This summer's Chesapeake Bay "dead zone" is expected to be smaller than the long-term average, according to a forecast released today by researchers from the University of Michigan, Chesapeake Bay Program, University of Maryland Center for Environmental Science and U.S. Geological Survey.

A team of Florida State University researchers has uncovered a way to use low-energy light to manipulate photopolymers or plastic films—a finding that has implications for a wide range of technologies that use light as an energy source to create shape-shifting structures.

Some Americans still say no to getting any COVID-19 vaccination even as others are currently committing to their fourth shot. What accounts for differences in attitude between the fully vaccinated and those who opt out? The biggest factor could be political ideology, a new survey from the University of Houston shows.

A chemical compound discovered in 2019 in the wintertime air of Fairbanks, Alaska accounts for a significant portion of the community's fine particulate pollution, according to new research that seeks to better understand the causes and makeup of the dirty air.

The "anomie" concept—that the society is disintegrating and losing moral standards—explains why people with low socioeconomic status trust politics less than those with a higher one, concludes a new study published in the scientific journal Social Psychological Bulletin.

The BirdNET app, a free machine-learning powered tool that can identify over 3,000 birds by sound alone, generates reliable scientific data and makes it easier for people to contribute citizen-science data on birds by simply recording sounds.

NASA scientists hope to solve a fundamental mystery about Mars' atmosphere, and you can help. They've organized a project called Cloudspotting on Mars that invites the public to identify Martian clouds using the citizen science platform Zooniverse. The information may help researchers figure out why the planet's atmosphere is just 1% as dense as Earth's even though ample evidence suggests the planet used to have a much thicker atmosphere.

A new Concordia study of early childhood bilingualism in Canada reveals a portrait of language acquisition in the home that reflects the country's diversity. Immigration patterns, urban–rural demography and Indigenous populations are some of the main contributing factors to this varied picture.

Through CRISPR and other gene-editing technologies, researchers and developers are poised to bring dozens—if not hundreds—of new products to grocery stores: mushrooms with longer shelf lives, drought-resistant corn and bananas impervious to a fungus threatening the global supply. A few, including a soybean variety that produces a healthier cooking oil, are already being sold commercially in the U.S.

Chronic wasting disease (CWD) is an infectious disease that affects the central nervous systems of animals, typically affecting cervids such as deer, elk and moose.

Salmon famously travel hundreds of miles upstream to reach their home waters to spawn, but climate change is shrinking their destination. A new study offers high-resolution details on how Chinook salmon habitats are being lost on Bear Valley Creek, a headwater stream of the Salmon River in central Idaho.

In the meat industry, it's common practice to turn the whole animal into food products. In the fish industry, over half of the weight of the fish ends up as side-streams which never reach our plates. This takes a toll on the environment and is out of step with Swedish food and fisheries strategies. Now, food researchers at Chalmers are introducing a new sorting technology that means we get five good cuts from fish and not just the filet. A herring processing plant on Sweden's west coast is already implementing the new method.

Increased flooding in the U.S. is exposing more people to industrial pollution, especially in racially marginalized urban communities, according to new research from Rice University, New York University and Brown University.

A team of researchers has assembled a reference genome for Solanum lycopersicoides, a wild relative of the cultivated tomato, and developed web-based tools to help plant researchers and breeders improve the crop.

A new paper examining whether heated tobacco products emit smoke has been published in the academic journal American Chemical Society Omega.

The Wake Forest Institute for Regenerative Medicine (WFIRM) researchers, who were the first to identify that stem cells in human urine have potential for tissue regenerative effects, continue their investigation into the power of these cells. In their latest published study, they focus on how telomerase activity affects the regenerative potential of these and other types of stem cells.

The emerging field of valleytronics, which exploits the momentum preference of excited electrons, or excitons, in a variety of optoelectronic devices, is closely tied to the fabrication of novel 2D materials just atoms thick. This month, a group of valleytronics researchers from Central South University in Changsha, China, have developed one such 2D material that significantly enhances the utility of these exciting particles.

A new study of the ancient world of Anatolia—now Turkey—shows how they adapted to climate change but offers a warning for today's climate emergency.

Since 2009, many central U.S. residents have faced increasing earthquake activity. Research has suggested that these tremors are linked to wastewater injection into deep wells by oil and gas companies. However, the precise dynamics of these earthquakes are still being revealed.

Although the microbiome—the collection of all microbes that live in the body—in the fecal matter of dogs has been investigated extensively, those studies have mostly been limited to domesticated dogs. In a new study, researchers have sampled the fecal microbiomes across diverse geographical populations to better understand what they look like around the world.

They're not too cuddly, but bearded dragons are working their way into the hearts and homes of American families. And now, researchers at the University of Illinois Urbana-Champaign are ensuring that these scaly companion animals receive the same medical care as Fluffy, Stripes, and Snowball.
