Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new paper in PNAS focused on the spatial patterns found in drylands offers important empirical evidence validating the models. Drylands make up 40 percent of the Earth’s landmass and are places where water is the limiting resource for life. They often display a characteristic ...

DURHAM, N.C. – As the HIV virus glides up outside a human cell to dock and possibly inject its deadly cargo of genetic code, there’s a spectacularly brief moment in which a tiny piece of its surface snaps open to begin the process of infection. Seeing that structure snap open and shut in mere millionths of a second is giving Duke Human Vaccine Institute (DHVI) investigators a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine. Their findings appear Feb. 2 in Science Advances. Being able to attach an antibody specifically to ...

Some hereditary genetic defects cause an exaggerated immune response that can be fatal. Using the CRISPR-Cas9 gene-editing tool, such defects can be corrected, thus normalizing the immune response, as researchers led by Klaus Rajewsky from the Max Delbrück Center now report in “Science Immunology.” Familial hemophagocytic lymphohistiocytosis (FHL) is a rare disease of the immune system that usually occurs in infants and young children under the age of 18 months. The condition is severe and has a high mortality rate. It is caused by various gene mutations that prevent cytotoxic T cells from functioning normally. These ...

BIRMINGHAM, Ala. – Cigarette smoke exposure is associated with the development and severity of chronic obstructive pulmonary disease, or COPD, which is the third leading cause of death worldwide. Cigarette smoke contains 2 to 3 micrograms of cadmium, a highly toxic metal and environmental pollutant, per cigarette. Burning tobacco releases cadmium oxide that can be adsorbed onto microparticles in smoke that travel deep into the lungs. Furthermore, the body is not able to remove cadmium, which accumulates in longtime smokers. In ...

First-of-its-kind research on cryptocurrency finds that the most regulated coins create the most efficient markets. That crypto regulation, often provided by cryptocurrency exchanges like Binance, can also help protect investors by providing reliable, public information. “Both small and institutional investors should know, if they invest in coins without any regulation, they may suffer from price manipulation or a severe lack of insider information,” said Liangfei Qiu, a University of Florida professor of business and one of the authors of the new study. “Instead, they may want to invest in coins listed with platforms ...

The ancient astronomer Nicolaus Copernicus was the first scientist to document the theory that the sun is the center of the universe in his book, De Revolutionibus Orbium Coelestium (On the Revolutions of the Heavenly Spheres). That first edition book, along with a delicate manuscript from astronomer Johannes de Sacrobosco, that is contrary to Copernicus’ groundbreaking theory, has now found a permanent home at Rochester Institute of Technology. The texts were donated to RIT’s Cary Graphic Arts Collection, one of the world’s premier libraries on graphic communication history and practices. The donor is Irene ...

The genetic material, in the form of DNA, contains the information that is crucial for the correct functioning of every human and animal cell. From this information repository, RNA, an intermediate between DNA and protein, the functional unit of the cell, is generated. During this process, the genetic information must be tailored for specific cell functions. Information that is not needed (introns) is cut out of the RNA and the important components for proteins (exons) are preserved. A team of researchers led by Professor Dr Mirka Uhlirova at the University of Cologne’s CECAD Cluster of ...

RICHLAND, Wash.—Doctors have nearly a dozen new targeted drugs to treat patients with acute myeloid leukemia, or AML, yet three of four patients still die within five years. Some patients succumb within just a month or two, despite the battery of drugs used to treat the aggressive blood disease, where blood cells don’t develop properly.   A new study draws on a field of science known as proteogenomics to try to improve the outlook. In a paper published Jan. 16 in Cell Reports Medicine, scientists report new ...

Oxidation can degrade the properties and functionality of metals. However, a research team co-led by scientists from City University of Hong Kong (CityU) recently found that severely oxidized metallic glass nanotubes can attain an ultrahigh recoverable elastic strain, outperforming most conventional super-elastic metals. They also discovered the physical mechanisms underpinning this super-elasticity. Their discovery implies that oxidation in low-dimension metallic glass can result in unique properties for ...

One of the study authors, Professor Hans Frankort, Professor of Strategy at Bayes Business School, City, University of London, said: “Sports – particularly motorsports – can be a good proxy for several other industries as they are extremely competitive: if you don’t perform and progress you may be out. Workers in sectors such as consultancy and financial services face similar pressures.” The peer reviewed paper, which has been published on the website of the Academy of Management Journal, found that riders systematically adjusted their internal ...

LAWRENCE — The study of “exoplanets,” the sci-fi-sounding name for all planets in the cosmos beyond our own solar system, is a pretty new field. Mainly, exoplanet researchers like those in the ExoLab at the University of Kansas use data from space-borne telescopes such as the Hubble Space Telescope and Webb Space Telescope. Whenever news headlines offer findings of “Earth-like” planets or planets with the potential to support humanity, they’re talking about exoplanets within our own Milky Way. Jonathan Brande, a doctoral candidate in the ExoLab at the University of Kansas, has just published findings in the open-access ...

East Hanover, NJ – February 2, 2024 – Labor market indicators showed slight declines over the last two months for both people with and without disabilities, according to today’s National Trends in Disability Employment – semi-monthly update (nTIDE), issued by Kessler Foundation and the University of New Hampshire’s Institute on Disability (UNH-IOD). These declines may reflect the end of seasonal employment and the impact of the Federal Reserve’s anti-inflationary measures aimed at minimizing the risk of recession. ...

New research has shown a new type of inhibitor drug could prevent microvascular diabetic complications, such as diabetic eye and kidney disease.  The University of Bristol-led research is published in Cardiovascular Diabetology. Diabetes, a disease which results in uncontrolled blood glucose levels, is estimated to affect one in 11 adults worldwide.  Even when managed, this common disease can result in life-altering complications, impacting the small blood vessels of the body, known as the microvasculature.   While treatments ...

The University of Tennessee, Knoxville, continued to expand its impact and research footprint last year, breaking university records for both research expenditures and sponsored project awards for the second straight year. Since 2019, UT has more than doubled its sponsored project awards, reaching a record $428 million in the fiscal year that ended in June 2023. The university also reported $339 million in research expenditures in fiscal year 2023, an increase of nearly $15 million over fiscal year 2022 and the highest amount in UT history. Research expenditures include internal and external funds that support UT research ...

In the fossil record, trees typically are preserved with only their trunks. They don’t usually include any leaves to show what their canopies and overall forms may have looked like. But now, researchers reporting in the journal Current Biology on February 2 describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.  “The way in which this tree produced hugely long leaves around its spindly trunk, and the sheer number over a short length of trunk, is startling,” says Robert Gastaldo of Colby College in Waterville, Maine. The forms taken by these ...

Embargoed until 11am ET USA/4pm GMT UK on Friday 2 February (Current Biology embargo) -With pictures- Fruit flies have provided scientists with new insight into the genetic basis for the rapid evolution of male external genitalia driven by sexual selection. Secondary sexual characteristics such as peacocks’ tails and the male external genitalia of insects are known to be among the fastest evolving animal body parts. It is thought that this is driven by sexual selection including through female choice and the different evolutionary needs of each sex to find the right mate and maximise their fitness. Now scientists at Durham University and Oxford ...

About The Study: The findings of this study of 1,404 mental health treatment facilities indicate that there were no differences in the availability of mental telehealth services based on the prospective patient’s clinical condition, perceived race or ethnicity, or sex; however, differences were found at the facility-, county-, and state-level. These findings suggest widespread disparities in who has access to which telehealth services throughout the U.S.  Authors: Jonathan Cantor, Ph.D., of the RAND Corporation in Santa Monica, California, is the corresponding author. To access the embargoed study: Visit ...

About The Study: This study including 432,000 patients who underwent major surgery for eight cancer types found an increased rate of venous thromboembolism associated with cancer surgery. The risk persisted for about two to four months postoperatively but varied between cancer types. The increased rate is likely explained by the underlying cancer disease and adjuvant treatments. The results highlight the need for individualized venous thromboembolism risk evaluation and prophylaxis regimens for patients undergoing different surgery for different cancers. Authors: Johan ...

Telehealth availability for mental health care varies significantly across states -- from less than half of treatment facilities contacted in states like Mississippi and South Carolina to every facility contacted in states like Maine and Oregon, according to a new RAND study.   Researchers found there were differences in services offered depending on whether a mental health treatment facility was located in in a rural or metropolitan area.   The types of services offered -- and the types of telehealth modalities available -- also varied widely among ...

About The Study: The results of this study of 89,000 adults suggest that wellness visits and preventive health screenings in the U.S. have not returned to pre-pandemic levels. Screening rates for blood pressure, cholesterol, blood glucose, and common cancers were lower in 2021 versus 2019, and varied across racial and ethnic groups, with Asian adults experiencing the most pronounced declines. These findings support the need for public health efforts to increase the use of preventive health screenings among eligible adults.  Authors: Rishi K. Wadhera, ...

A team of researchers from the Badalona Applied Research Group in Oncology (B·ARGO) and the Urologic Tumours Unit of the Institut Català d'Oncologia (ICO) and the Germans Trias i Pujol Research Institute (IGTP) have found a new therapeutic strategy for patients with a specific subtype of metastatic prostate cancer resistant to standard chemotherapy treatment with docetaxel. In this study, published in the journal Frontiers in Pharmacology, they propose a new treatment based on a combination of kinase inhibitors in patients who inevitably stop responding to docetaxel. The team found that resistance to this drug is associated with the hyperactivation ...
