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 ...

  Media kit New research suggests that a realistic estimate of additional global forest carbon-storage potential is approximately 226 gigatonnes of carbon—enough to make a meaningful contribution to slowing climate change.   The study, published today in the journal Nature, highlights the critical importance of forest conservation, restoration and sustainable management in moving toward international climate and biodiversity targets. It involved hundreds of scientists around the world, who stress that this potential can be achieved by incentivizing community-driven efforts to promote biodiversity.   Forest ...

ST. LOUIS, MO, November 13, 2023 — An international research team led by James Umen, PhD, member, Donald Danforth Plant Science Center has made an unexpected discovery of a biased counting mechanism used by the single-celled green alga Chlamydomonas to control cell division. Chlamydomonas cells can grow very large and then divide multiple times in succession. The team found that the number of divisions a mother cell undertakes to restore its daughters to the correct starting size deviates from the mathematical optimum that was assumed to dictate ...

In a recent publication in Nature Communications, a joint research team of Johannes Gutenberg University Mainz (JGU), the University of Cologne, and the University of Oldenburg has presented their findings on the functioning of an atypical cryptochrome protein (Cry). These proteins are found in a variety of organisms, and they are often involved in light-controlled biological processes. The marine bristle worm Platynereis dumerilii, for example, employs a special Cry protein designated L-Cry to distinguish between sunlight and moonlight as well as between different moon phases. This is essential for the worms ...

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 ...

A form of brain-inspired computing that exploits the intrinsic physical properties of a material to dramatically reduce energy use is now a step closer to reality, thanks to a new study led by UCL and Imperial College London researchers. In the new study, published in the journal Nature Materials, an international team of researchers used chiral (twisted) magnets as their computational medium and found that, by applying an external magnetic field and changing temperature, the physical properties of these materials could be adapted to suit different machine-learning tasks. Such an approach, known as physical reservoir ...

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. The challenge is to find a ...

Young adults are now more likely to vape than to use traditional cigarettes. After years of public health success in decreasing the numbers of people using cigarettes, researchers are seeing striking increases in the numbers of young people who use e-cigarettes regularly – so much so that, for the first time, there are more young people who begin to use nicotine through vaping rather than through cigarettes.   “We now have a shift such that there are more ‘never smokers’ who vape than established smokers,” ...

About The Study: This analysis finds that COVID-19 and the drug overdose epidemic were major contributors to the widening gender gap in life expectancy (nearly six years) between women and men in recent years. Men experienced higher COVID-19 death rates for likely multifactorial reasons, including higher burden of comorbidities and differences in health behaviors and socioeconomic factors, such as labor force participation, incarceration, and homelessness. Differentially worsening mortality from diabetes, heart disease, homicide, and suicide suggest that chronic metabolic disease and mental illness may also contribute.   Authors: Brandon W. Yan, M.D., ...

About The Study: The data from this nationally representative survey study reveal a shift in tobacco use among young adults (ages 18-24), showing historically low cigarette use, which has positive public health significance. However, e-cigarette use is higher (14.5%) than reported previously, coinciding with the introduction of salt-based devices in 2015 to 2018. Over half of established vaping young adults never regularly smoked. Research suggests that exclusive e-cigarette users are unlikely to ...

About The Study: The findings of this study indicate an increase in the prevalence of breastfeeding initiation and breastfeeding duration at 12 months from 1999 to 2018 in the U.S. Temporal changes of breastfeeding duration at 12 months were more prevalent among male infants, older mothers, Mexican American and multiracial participants, and households with higher income.
