(Press-News.org) About The Study: Between 1999 and 2020, deaths coded as being caused by falls among adults age 65 or older in the U.S. increased in number and rates for the overall population and for every population subgroup, although the magnitude of the increase varied. However, the relative ranking of the different groups has not changed over time.

Extracting the best flavor from coffee
2023-05-09
WASHINGTON, May 9, 2023 – Espresso coffee is brewed by first grinding roasted coffee beans into grains. Hot water then forces its way through a bed of coffee grains at high pressure, and the soluble content of the coffee grains dissolves into the water (extraction) to produce espresso.
In 2020, researchers found that more finely ground coffee beans brew a weaker espresso. This counterintuitive experimental result makes sense if, for some reason, regions exist within the coffee bed where less or even no coffee is extracted. This uneven extraction becomes more pronounced when coffee is ground more finely.

Preserving pine forests by understanding beetle flight
2023-05-09
WASHINGTON, May 9, 2023 – The mountain pine beetle is one of the main causes of tree mortality in the pine forests of North America. For example, the insect has killed thousands of acres of pine forest in British Columbia and Alberta, and as a result, the areas are more vulnerable to wildfire. Increased tree mortality has turned Canada’s forests into a large net source of atmospheric carbon dioxide – emitted from the burned or decaying wood of dead trees – rather than a sink.
In Physics of Fluids, by AIP Publishing, researchers from the University of Alberta studied the flight performance of the mountain pine beetle from a fluid mechanics and an entomological perspective. ...
US gun violence: half of people from Chicago witness a shooting by age 40, study suggests
2023-05-09
Study following Chicagoans over a 25-year period suggests over half of the city’s Black and Hispanic population, and a quarter of its White population, have seen a shooting by age 40.
Researchers followed over two thousand people, with 50% of all the study’s participants witnessing a shooting.
Average age when first witnessing a shooting was just 14 years old.
Women only slightly less likely than men to witness shootings, despite men being far more likely to get shot.
Such levels of violence exposure may cause chronic stress and knock-on health implications for populations in Chicago and elsewhere.

Assessment of medical cannabis and health-related quality of life
2023-05-09
About The Study: In this study, patients using medical cannabis reported improvements in health-related quality of life, which were mostly sustained over time. Adverse events were rarely serious but common, highlighting the need for caution with prescribing medical cannabis.
Authors: Thomas R. Arkell, Ph.D., of the Swinburne University of Technology in Melbourne, Victoria, Australia, is the corresponding author.

Making vaccines longer lasting
2023-05-09
The SARS-Cov-2 pandemic illustrates how variable vaccines can be in their length of efficacy, with regular boosters needed to keep people protected. In comparison, the immunity generated by a single vaccination against the measles virus can last decades.
It has always remained a scientific mystery as to why only some vaccines lead to life-long protection. Now a paper published in the journal, Immunity, led by Prof. David Tarlinton and Dr Marcus Robinson, both from Monash University’s Central Clinical School in Melbourne, Australia, has found that the clue likely lies in the body producing a unique subtype of an immune cell in response to some ...
Long-term study pinpoints who has been shot and witnessed shootings by race, sex, and birth year
2023-05-09
Exposure to gun violence is one of the great traumas of American life, but its harms are not equally distributed. In a first-of-its-kind study published Tuesday in JAMA Network Open, a Harvard sociology professor and his colleagues set out to examine exposure to shootings by race, sex, and birth year in a long-term study that followed respondents from childhood up to age 40.
“The idea here is to take a life-course perspective,” said Robert J. Sampson, the Woodford L. and Ann A. Flowers University Professor. ...
Not all statins are created equal
2023-05-09
We’ve all recently gotten a crash-course in drug repurposing, thanks to near-daily news reports about efforts to identify existing medicines that could help treat COVID-19 in the early phase of the pandemic. A team of scientists at the Wyss Institute at Harvard University jumped into the fray in the spring of 2020, applying novel computational drug repurposing approaches to confront the COVID-19 challenge. This early work led to the surprising prediction that a some, but not all, types of statins (drugs that are widely prescribed to lower cholesterol) might protect patients against SARS-CoV-2 infection. In the flurry of clinical studies being published by other scientists studying ...
Motion capture and 3D scans bring history to life for new Dambusters docudrama
2023-05-09
A new docudrama featuring the attack on the Sorpe Dam, using motion capture technology and 3D scans to create life-like digital representations of RAF 617 Squadron aircrew, is being premiered in Bristol on 13 May 2023 to coincide with the 80th anniversary of the Dambusters raid.
Bristol-based film maker Andrew Panton worked with University of Bath researchers at CAMERA, using the latest digital technology to recreate specific scenes for a film featuring the attack on the Sorpe Dam.
Andrew started working on the documentary in 2017 with the last surviving Dambuster George ...
Exploring the underground connections between trees
2023-05-09
Fungal networks interconnecting trees in a forest is a key factor that determines the nature of forests and their response to climate change. These networks have also been viewed as a means for trees to help their offspring and other tree-friends, according to the increasingly popular “mother-tree hypothesis”. An international group of researchers re-examined the evidence for and against this hypothesis in a new study.
Trees in a forest are interconnected through thread-like structures of symbiotic fungi, called hyphae, which together form an underground network called a mycorrhizal network. While it is well known that ...
New research sheds light on how human vision perceives scale
2023-05-09
Researchers from Aston University and the University of York have discovered new insights into how the human brain makes perceptual judgements of the external world.
The study, published on 8 May in the journal PLOS ONE, explored the computational mechanisms used by the human brain to perceive the size of objects in the world around us.
The research, led by Professor Tim Meese, in the School of Optometry at Aston University and Dr Daniel Baker in the Department of Psychology at University of York, tells us more about how our visual system can exploit ‘defocus blur’ to infer perceptual scale, but that it does ...
