In patients with severe artery blockage in the lower leg, an artery-supporting device called a resorbable scaffold is superior to angioplasty, which has been the standard treatment, according to the results of a large international clinical trial co-led by researchers at Weill Cornell Medicine and NewYork-Presbyterian. Angioplasty involves the widening of a narrowed artery with a small, balloon-like mechanism. A resorbable scaffold is a stent-like structure that props the artery open but is biodegradable and dissolves within a few years, avoiding some of the potential complications of a permanent ...

A compound—one of 27 million screened in a library of potential new drugs—reversed four types of chronic pain in animal studies, according to new research led by NYU College of Dentistry’s Pain Research Center and published in the Proceedings of the National Academy of Sciences (PNAS). The small molecule, which binds to an inner region of a calcium channel to indirectly regulate it, outperformed gabapentin without troublesome side effects, providing a promising candidate for treating pain. Calcium channels play a central role in pain signaling, in part through the release of neurotransmitters such as glutamate and GABA— “the ...

An international team of researchers has developed a handheld, non-invasive device that can detect biomarkers for Alzheimer’s and Parkinson’s Diseases. The biosensor can also transmit the results wirelessly to a laptop or smartphone.  The team tested the device on in vitro samples from patients and showed that it is as accurate as the state of the art. Ultimately, researchers plan to test saliva and urine samples with the biosensor. The device could be modified to detect biomarkers for other conditions as well.  Researchers present their findings ...

A research team from the University of Cologne, in collaboration with colleagues from the Leibniz Institute for Food Systems Biology in Freising, has discovered a receptor for bitter taste in twelve different cartilaginous fish (sharks and rays). The receptor belongs to the so-called taste receptors type 2 (T2R), which also make humans perceive bitter and potentially toxic foods. Until now, it was assumed that such receptors only occur in bony vertebrates. The work was published under the title ‘A singular shark bitter taste receptor provides insights into the evolution of bitter taste perception’ ...

To paraphrase Mark Twain, reports of declining phytoplankton in the North Atlantic may have been greatly exaggerated. A prominent 2019 study used ice cores in Antarctica to suggest that marine productivity in the North Atlantic had declined by 10% during the industrial era, with worrying implications that the trend might continue. But new research led by the University of Washington shows that marine phytoplankton — on which larger organisms throughout the marine ecosystem depend — may be more stable than believed in the North Atlantic. The team’s analysis of an ice core going ...

People with arthritis who report more negative feelings about how they are aging tend to get less physical activity and perceive themselves as less healthy, according to a new study by researchers at Hospital for Special Surgery (HSS) and Weill Cornell Medicine. However, self-perception of good health explained the effect of negative thinking – providing an opportunity for clinicians to focus on a patient’s outlook on aging as well as their overall health. “Physical activity is essential for older adults with arthritis, as it can help to reduce pain and stiffness, improve ...

Researchers at Karolinska Institutet and SciLifeLab in Sweden have combined artificial intelligence (AI) techniques used in satellite imaging and community ecology to interpret large amounts of data from tumour tissue. The method, presented in the journal Nature Communications, could contribute to more personalised treatment of cancer patients. While recent advances in tumour imaging provide a great insight into the microscopic world of tumours, the challenge is to interpret the huge amount of data generated. With hundreds of molecules being measured simultaneously in tens or hundreds of thousands of cells, it has become difficult for researchers to know what molecules and cells ...

Artificial intelligence (AI) is on the rise. Until now, AI applications generally have “black box” character: How AI arrives at its results remains hidden. Prof. Dr. Jürgen Bajorath, a cheminformatics scientist at the University of Bonn, and his team have developed a method that reveals how certain AI applications work in pharmaceutical research. The results are unexpected: the AI programs largely remembered known data and hardly learned specific chemical interactions when predicting drug potency. The results have now been published in Nature Machine Intelligence. Which drug molecule is most effective? Researchers are feverishly ...

BINGHAMTON, N.Y. -- Migrant couples who can effectively balance the culture of their homeland while adapting to the dominant culture of their new home are more likely to have a better relationship, according to newly published research from psychologists at Binghamton University, State University of New York.  “When immigrants venture into a new country, they embark on a journey of blending cultures while keeping their roots alive,“ said Binghamton University PhD candidate Quinn Hendershot. “There has been limited research on how their ability to adjust to a new culture while embracing the cultures of their homeland can affect the relationship.” Hendershot ...

– The National Institutes of Health (NIH) has awarded $1.1 million to a team led by Worcester Polytechnic Institute (WPI) researcher Ulkuhan Guler to develop a first-of-its-kind wearable sensor for premature infants that will address racial bias in healthcare by monitoring oxygen levels two different ways and correcting the measurements to account for variations in skin color. The four-year project will create a convenient, affordable, noninvasive sensor about the size of a bandage that will enable infants at risk of lung disease to leave hospitals sooner and be accurately monitored at home, said Guler, an associate professor in the Department ...

HOUSTON – (Nov.13, 2023) – When it comes to chemical reactions, fluorine has a reputation as a ‘magic bullet atom’ for its ability to increase a drug’s absorption and prolong its lifetime. However, traditional methods of adding it to compounds entail expensive materials and can be difficult to pull off. Rice University scientists developed a reliable and cost-effective process of adding fluorine to molecules for increased pharmaceutical drug efficiency using an iron and ...

People in many parts of the United States possess few chances for the robust community engagement that underpins healthy democracies, according to a new report that for the first time maps civic opportunity across the country. The heat map created by Johns Hopkins University’s SNF Agora Institute, reveals patterns of inequality in civic opportunity tied to race, class, immigration status and education. Researchers also found that a great deal of civic engagement happens through local faith institutions and social and fraternal organizations, not D.C.-based advocacy organizations that tend to carry political clout. The report is the initial phase ...

Immigration to and living on Mars have long been depicted in science fiction works. But before dream turns into reality, there is a hurdle man has to overcome -- the lack of essential chemicals such as oxygen for long-term survival on the planet. However, hope looms up thanks to recent discovery of water activity on Mars. Scientists are now exploring the possibility of decomposing water to produce oxygen through electrochemical water oxidation driven by solar power with the help of oxygen evolution reaction (OER) catalysts.
