Association of smoking cessation and cardiovascular, cancer, and respiratory mortality

JAMA Internal Medicine

2023-11-27

(Press-News.org) About The Study: Excess cardiovascular mortality among former smokers was about one-third that of continuing smokers within the first decade after quitting, and the cardiovascular mortality rate of former smokers was similar to that of never smokers 20 to 29 years after quitting in this study of 438,000 U.S. adults. These findings emphasize that with sustained cessation, cause-specific mortality rates among former smokers may eventually approximate those of never smokers.

Brain boost: Can a coach help elders at risk for Alzheimer’s?

2023-11-27

Brain Boost: Can a Coach Help Elders at Risk for Alzheimer’s? Study shows cognitive improvements when participants keep active and socially engaged, control blood pressure and diabetes. As more medications move towards federal approval for Alzheimer’s disease, a new study led by researchers at UC San Francisco and Kaiser Permanente Washington has found that personalized health and lifestyle changes can delay or even prevent memory loss for higher-risk older adults. The two-year study compared cognitive ...

Early-stage stem cell therapy trial shows promise for treating progressive MS

2023-11-27

An international team has shown that the injection of a type of stem cell into the brains of patients living with progressive multiple sclerosis (MS) is safe, well tolerated and has a long-lasting effect that appears to protect the brain from further damage. The study, led by scientists at the University of Cambridge, University of Milan Bicocca and Hospital Casa Sollievo della Sofferenza (Italy), is a step towards developing an advanced cell therapy treatment for progressive MS. Over 2 million people live with MS worldwide, ...

Irritability, agitation, and anxiety in Alzheimer’s patients caused by brain inflammation, study says

2023-11-27

PITTSBURGH, Nov. 27, 2023 – Common neuropsychiatric symptoms that doctors see in Alzheimer’s disease patients originate from brain inflammation rather than amyloid and tau proteins, report University of Pittsburgh School of Medicine researchers today in JAMA Network Open. The finding strengthens mounting evidence for the role of neuroinflammation in Alzheimer’s progression and suggests new pathways for the development of therapies targeting neurological symptoms of the disease. “Neuropsychiatric symptoms such as irritability, agitation, anxiety and depression are among the most difficult ...

Sensitive ecosystems at risk from mine waste

2023-11-27

Nearly a third of the world’s mine tailings are stored within or near protected conservation areas, University of Queensland research has found. A study led by UQ’s Bora Aska, from the Sustainable Minerals Institute and School of the Environment, said these waste facilities pose an enormous risk to some of earth’s most precious species and landscapes. “Mine tailings contain the waste and residue that remains after mineral processing, and the storage facilities built to contain it are some of the world’s largest engineered structures,” Ms Aska said. “We found of the 1,721 disclosed tailings ...

Genes influence whether infants prefer to look at faces or non-social objects

2023-11-27

Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. This has now been demonstrated by researchers at Uppsala University and Karolinska Institutet. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about. The study has been published in the scientific journal Nature Human Behaviour. The way in which we explore our environment with our eyes affects what we notice, think about and learn. The new study analysed preference for faces versus non-social objects in ...

Collaboration between women helps close the gender gap in ice core science

2023-11-27

A Perspective article published today in Nature Geoscience tackles the longstanding issue of gender representation in science, focusing on the field of ice core science. Prior work has shown that despite progress toward gender parity over the past fifty years1, women continue to be significantly underrepresented within the discipline of Earth sciences2 and receive disproportionately fewer opportunities for recognition, such as invited talks, awards, and nominations3. This lack of opportunity can have long-term negative impacts on women’s careers. To help address these persistent gender gaps, the study evaluates patterns related to women’s publication in ice core science over the ...

Stanford Medicine study reveals why we value things more when they cost us more

2023-11-27

Ahab hunting down Moby Dick. Wile E. Coyote chasing the Road Runner. Learning Latin. Walking over hot coals. Standing in a long line for boba tea or entrance to a small, overpriced clothing retail store. Forking up for luxury nonsense. What do these activities have in common? They’re all examples of the overvaluation of what economists call “sunk costs”: the price you’ve already irretrievably paid in time, money, effort, suffering or any combination of them for an item, an experience or a sense of self-esteem. It’s a ...

Innovative design achieves tenfold better resolution for functional MRI brain imaging

2023-11-27

An intense international effort to improve the resolution of magnetic resonance imaging (MRI) for studying the human brain has culminated in an ultra-high resolution 7 Tesla scanner that records up to 10 times more detail than current 7T scanners and over 50 times more detail than current 3T scanners, the mainstay of most hospitals. The dramatically improved resolution means that scientists can see functional MRI (fMRI) features 0.4 millimeters across, compared to the 2 or 3 millimeters typical of today's standard 3T fMRIs. "The NexGen 7T scanner is a new tool that allows us to look at the brain circuitry underlying different diseases of the brain with ...

Hamburg collaboration paves the way to cleaner technologies for industry

2023-11-27

During the nearly five decades of its operation, the European Molecular Biology Laboratory (EMBL) in Hamburg has developed many fruitful collaborations with other scientific institutions located in the Hamburg metropolitan area. One example is the long-lasting collaboration between researchers at EMBL Hamburg and the Center for Biobased Solutions (CBBS) at the Hamburg University of Technology (TUHH), which has recently yielded new insights into the structure and function of a lipid-degrading enzyme found in a microbe adapted to living in extreme conditions. The findings could help improve ...

Pioneering research method reveals bluefin tuna’s fate

2023-11-27

The return of bluefin tuna to Northern European waters is a conservation success story, but rising sea temperatures in their Mediterranean nursery grounds mean this recovery may be short-lived, according to new research led by the University of Southampton. Temperatures expected in the Mediterranean within the next 50 years are expected to drive juvenile tuna out of the Mediterranean, where they may be accidentally caught in existing sardine and anchovy fisheries – requiring fishery managers to adapt their methods to allow tuna nurseries to establish. Outlining the research, published in Nature, lead author Clive Trueman, Professor of Geochemical Ecology ...
