For years, we’ve known that a special kind of molecular assembly known as a “polyelectrolyte complex” helps your cells keep themselves organized. These complexes are very good at forming interfaces to keep two liquids separated: your cells use them to create compartments. These abilities have led scientists to consider them for technological applications, including filtering water, better batteries, and even underwater glue, as well as for better pharmaceutical drugs. But for decades, no one knew exactly ...

Researchers from the University of Tokyo and Stanford University show what differentiates slow and fast earthquakes and how their magnitudes vary with time.     Normally, earthquakes last up to a few minutes and radiate strong seismic waves. But around 23 years ago, scientists discovered an unusual slow-slip phenomena called slow earthquakes. Slow earthquakes last days or even months. Though they involve significant tectonic movement, you may never feel them. Since slow earthquakes could indicate future fast earthquakes, monitoring and ...

A research team led by Prof. Yossi Paltiel at the Hebrew University of Jerusalem with groups from HUJI, Weizmann and IST Austria new study reveals the influence of nuclear spin on biological processes. This discovery challenges long-held assumptions and opens up exciting possibilities for advancements in biotechnology and quantum biology. Scientists have long believed that nuclear spin had no impact on biological processes. However, recent research has shown that certain isotopes behave differently due to their nuclear spin. The team focused on stable oxygen isotopes (16O, 17O, 18O) and found ...

University of Texas at Dallas researchers are using geospatial mapping techniques to identify social and environmental obstacles in communities that might impede burn injury survivors’ reentry into society. The project is designed to help patients with burn injuries better adapt to their lives after medical discharge, including improving patient access to transportation, employment, food and other necessities. “Our study looks at how people who survive burn injuries reenter the community,” said Dr. Richard Scotch, program head of sociology and a professor of public policy and political economy in the School of ...

Environmental change, such as ocean warming, alters resource competition and biodiversity. Thus, it is essential to understand how organisms respond to increased competition because changes in their size and metabolism affect the productivity of ecosystems. Competition has long been recognized as a driving force behind rapid evolution. Still, until now, a mechanistic framework for identifying the specific traits that evolve and their trajectories has yet to be developed. Researchers at Gulbenkian and Monash University turned to metabolic theory, which explicitly predicts how competition shapes the evolution of metabolism ...

The REPLANT Act provides money for the US Forest Service to plant more than a billion trees in the next nine years. The World Economic Forum aims to help plant a trillion trees around the world by 2030. Many US cities have plans to shade their streets with millions of trees. Major government and private funding is being invested in planting trees as a powerful tool to fight climate change, protect water, clean air, and cool cities. In short, trees are hot. But new research shows a troubling bottleneck that could threaten these efforts: U.S. ...

(Boston) – Tuberculosis (TB) disproportionately affects vulnerable populations including those with limited economic resources, HIV patients, those whose diet is deficient in nutrients and others. Resistant TB (MDR TB) does not respond to first line medications and is difficult to treat, requiring long regimens of 15-20 months that are associated with significant side effects and poor outcomes. Recently, new six-month regimens have been shown to have better results than the long-term treatments, with improved quality of life and health equity. But these novel regimens have not yet been adopted widely in the United States. ...

People solve new problems readily without any special training or practice by comparing them to familiar problems and extending the solution to the new problem. That process, known as analogical reasoning, has long been thought to be a uniquely human ability. But now people might have to make room for a new kid on the block. Research by UCLA psychologists shows that, astonishingly, the artificial intelligence language model GPT-3 performs about as well as college undergraduates when asked to solve the sort of reasoning problems that typically appear on intelligence tests and standardized tests such as the SAT. The study is published in Nature Human Behaviour. But the paper’s authors ...

Using energy from light to activate natural enzymes can help scientists create new-to-nature enzymatic reactions that support eco-friendly biomanufacturing — the production of fuels, plastics, and valuable chemicals from plants or other biological systems. Applying this photoenzymatic approach, researchers have developed a clean, efficient way to synthesize crucial chemical building blocks known as chiral amines, solving a longstanding challenge in synthetic chemistry. The study, published in Nature Catalysis, ...

Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers at the University of Bonn and ETH Zurich have now ...

(Boston)—In the face of ongoing political threats to the rights and well-being of sexual and gender minority (SGM) populations, public health and health care institutions and practitioners must explicitly address the needs of marginalized populations while ensuring that those with multiple marginalized identities are well represented in research, according to a commentary in JAMA Network Open.  “If we continue to exclude SGM in research, we will remain oblivious to the troubles they face in achieving health and well-being,” said lead author Carl G. Streed, Jr., MD, MPH, FACP, ...

An article to be published on July 31 in Nature Ecology & Evolution reveals that Luzio, the oldest human skeleton found in São Paulo state (Brazil), was a descendant of the ancestral population that settled the Americas at least 16,000 years ago and gave rise to all present-day Indigenous peoples, such as the Tupi. Based on the largest set of Brazilian archeological genomic data, the study reported in the article also offers an explanation for the disappearance of the oldest coastal communities, who built the icons of Brazilian archeology known as sambaquis, huge mounds of shells and fishbones used as dwellings, cemeteries and territorial boundaries. Archeologists often ...

The first bees evolved on an ancient supercontinent more than 120 million years ago, diversifying faster and spreading wider than previously suspected, a new study shows. Led by Washington State University researchers, the study provides a new best estimate for when and where bees first evolved. Newly published in the journal Current Biology, the project reconstructed the evolutionary history of bees, estimated their antiquity, and identified their likely geographical expansion around the world. The results indicate their point of origin was in western Gondwana, an ancient supercontinent that at that time included today's continents of Africa and South America. “There’s ...

CHAMPAIGN, Ill. — Scientists have identified a protein that plays a pivotal role in the action of several emerging cancer therapies. The researchers say the discovery will likely aid efforts to fine-tune the use of immunotherapies against several challenging cancers. They report their findings in the journal Cancer Research.  “Most anticancer drugs cause cancer cells to shrivel up and die in a controlled process known as apoptosis. But apoptosis does not usually strongly activate immune cells,” said David Shapiro, a professor ...
