While the American Rescue Plan Act provided a major infusion of economic aid to low-income and middle-class Americans, more should be done to tackle racial wealth inequality and the structural issues in the tax code that allow those at the top of the income distribution to benefit disproportionately from tax subsidies, an Indiana University professor wrote.

When it comes to electrons—one of the fundamental building blocks of all matter—there are lots of unanswered questions. How big are they? What are they made out of? What … are they?

High school students who have trouble paying attention in class are more likely to admit to cheating, a new study shows.

A study of the management plans for 118 conservation units in Brazil shows that 60% use unsuitable methods to detect the presence of deer, and that 38% do not even describe the method used. Conservation of these animals may be endangered as a result. Eight deer species occur in Brazil; three are red-listed as "vulnerable" by IUCN.

A contagious blood cancer jumped from one species of clam to another and spread among clams living in the Atlantic Ocean and Mediterranean Sea, shows a study published today in eLife.

The SETI Institute teamed up with Louisiana State University (LSU) and Mississippi State University (MSU) to help students design the science program for AstronetX PBC's first lunar-based camera (L-CAM 1). The scientific program planning is funded by a Gordon and Betty Moore Foundation grant to AstronetX. Additional funding for student participation is provided by the National Science Foundation (NSF) Research Experiences for Undergrads (REU) program at LSU.

Researchers from the University of Saskatchewan (USask) and St. Paul's Hospital in Saskatoon used the Canadian Light Source (CLS) at USask to help improve health outcomes for patients on dialysis.

ExxonMobil pledged Tuesday to reach "net zero" greenhouse gas emissions in its operations by 2050, but stopped short of extending the promise to products it sells throughout the global economy.

Shape-shifter molecules are in never-ending motion. Their structure fluctuates because the carbon bonds that hold them together constantly break up and form again. Researchers have now found a way to "tame" a shape-shifter molecule called bullvalene. In the journal Angewandte Chemie, they report that integrating the molecule into a coordination cage enables its shape-shifting behavior to be restricted through molecular recognition. Such form capturing could play a role in responsive materials.

University of Surrey researchers have developed a single-step procedure to put single-crystal silicon under more strain than has been achieved before. The discovery, which has a patent pending, could be crucial to the future development of silicon photonics, which underpins the technologies behind the internet-of-things, and is currently constrained by the lack of cheap, efficient, and easily integrated optical emitters.

An international team of researchers has found that extra-pair paternity in pied flycatchers leads to cooperation between males and females in feeding and fending off threats. In their paper published in Proceedings of the National Academy of Sciences, the group describes experiments they conducted with wild pied flycatchers given boxes for nesting and what they learned from them.

The skills of talented people in living in rural Cornwall are being wasted because of poor public transport and lack of internet access, a new study warns.

Conspiracy theories have circulated at all times, in all cultures, and among all populations. They routinely appear in conjunction with major incidents, such as those that today take the form of terrorist attacks, the COVID-19 pandemic, and presidential elections. As two recent surveys undertaken in 26 countries have demonstrated, an individual's belief in conspiracies tends to go hand-in-hand with his or her predilection for the political extremes.

University of South Australia scientists have made a surprising discovery in the origins of an antibiotic-resistant gene previously thought to have been confined to Adelaide.

Astronomers from Louisiana State University (LSU) and College of Charleston have performed photometric observations of a recurrent nova known as V2487 Oph. The observational campaign identified superflares on this source occurring almost daily. The finding was detailed in a paper published January 11 on arXiv.org.

Total suspended solids (TSS) affect water quality in recirculating aquaculture systems (RAS). The TSS with small particle size in traditional RAS is easy to accumulate, resulting in excessive ammonia and nitrite nitrogen, which limits the aquaculture capacity in RAS.

Investors react more negatively to transactions between firms in different countries if there is evidence of weak political affinity, a new study suggests.

The world's second-most megadiverse country stands to benefit ecologically, economically and socially through membership in the Earth Biogenome Project, according to research from the University of East Anglia (UEA).

Sperm can't claim all the credit for their strong swimming. Carpets of tiny hairs lining the inside of the fallopian tubes give them an extra boost, propelling them upwards.

Mitochondria are key components of our cells. Cell respiration and control of many metabolic and signaling processes take place within them. In order for the biochemical reactions to take place flawlessly, complex interactions between specialized protein molecules are required. Yet up to now, it wasn't known how many of the proteins in cells are also actual components of the mitochondria because the technology for such precise allocation was unavailable. A team working with Prof. Dr. Bettina Warscheid, Prof. Читать дальше...

In ecological terms, coniferous formations represent the biggest terrestrial carbon sink, they play an essential part in the pollination of the ecosystems where they grow and, moreover, help improve agricultural production. At the same time, from an economic point of view, they are the main source of raw material for wood industries.

Bluefin tuna have been tagged with state-of-the-art acoustic tracking tags for the first time in UK waters.

Carbon nanotubes are of great interest in both scientific research and commercial applications thanks to the unique properties of the material. A new thesis at Karlstad University looks at how the atomic structure influences the different properties of the material.

While the transition from today's service and brain-based economy to an environmentally sustainable economy will take decades to complete, the change has already begun. The time scale of the change is important to understand. I base my sense of the time scale on a change process that I, along with many residents of New York City, unknowingly lived through. It was New York's painful evolution from a manufacturing city to a city with a radically different economic base.

Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences recently obtained the annual distribution of Suaeda salsa (S. salsa) using remote sensing data from the past 30 years in Bohai Bay, China. They analyzed influencing factors of S. salsa changes.
