DALLAS - April 22, 2021 - Being Black or Hispanic, living in high-poverty neighborhoods, and having Medicaid or no insurance coverage are associated with higher mortality in men and women under 40 with cancer, a review by UT Southwestern Medical Center researchers found.
An international group of scientists from Italy, the USA, China and Russia have studied the relationship between collectivism, individualism and life satisfaction among young people aged 18-25 in four countries. They found that the higher the index of individualistic values at the country level, the higher the life satisfaction of young people's lives. At the individual level, however, collectivism was more significant for young people. In all countries, young people found a positive association between collectivism, particularly with regard to family ties, and life satisfaction.
Nagoya University researchers and colleagues in Japan have uncovered a molecular pathway that enhances chemotherapy resistance in some pancreatic cancer patients. Targeting an RNA to interrupt its activity could improve patient response to therapy and increase their overall survival.
A new molecular 'freeze frame' technique has allowed WEHI researchers to see key steps in how the protein MLKL kills cells.
Small proteins called 'monobodies' were used to freeze MLKL at different stages as it moved from a dormant to an activated state, a key process that enables an inflammatory form of cell death called necroptosis. The team were able to map how the three-dimensional structure of MLKL changed, revealing potential target sites that might be targets for drugs - a potential new approach to blocking necroptosis as a treatment for inflammatory diseases.
Thunderstorm development is not always dependent on atmospheric physics alone. Often, the surrounding landscape can influence convection, especially in regions with dramatic elevation changes. The Yangtze river basin in China's Jiangxi Province, which is surrounded by the Nanling Mountains, often experiences mesoscale convective systems (MCS) or squall line thunderstorms during the summer. These MCSs develop along the persistent mei-yu front, and often exhibit quickly developing parallel back-building, or training thunderstorms, resulting in torrential flooding. A research team led by Dr.
MINNEAPOLIS - Women who have migraine before menopause may have an increased risk of developing high blood pressure after menopause, according to a study published in the April 21, 2021, online issue of Neurology®, the medical journal of the American Academy of Neurology.
In 2016, an inflatable arch wreaked havoc at the Tour de France bicycle race when it deflated and collapsed on a cyclist, throwing him from his bike and delaying the race while officials scrambled to clear the debris from the road. Officials blamed a passing spectator's wayward belt buckle for the arch's collapse, but the real culprit was physics.
Despite our efforts to sort and recycle, less than 9% of plastic gets recycled in the U.S., and most ends up in landfill or the environment.
Swing voters in battleground states delivered Donald Trump his unexpected victory in the 2016 presidential election, suggests a new study coauthored by Yale political scientist Gregory A. Huber.
Substantial cuts in global greenhouse gas emissions could be achieved by raising water levels in agricultural peatlands, according to a new study in the journal Nature.
Peatlands occupy just three per cent of the world's land surface area but store a similar amount of carbon to all terrestrial vegetation, as well as supporting unique biodiversity.
In their natural state, they can mitigate climate change by continuously removing CO2 from the atmosphere and storing it securely under waterlogged conditions for thousands of years.
The natural menopause occurs when the menstrual periods cease due to the naturally decreased ovary function. There is a significant interindividual variation in the age at natural menopause but, on average, women undergo it around the age of 51 in Western countries. Furthermore, the length of the preceding menopausal transition, characterized by irregular menstrual cycles and menopausal symptoms, is also known to vary between individuals.
Perhaps no other ocean creature lives in the human imagination like the great white shark. But while great white sharks might be plentiful in the minds of beachgoers across the country, there are only a handful of places in the world where white sharks can be consistently found. In those areas -- such as Central California, Guadalupe Island Mexico, South Australia and South Africa -- they tend to be found aggregated in small hotspots, often located around seal colonies.
Meaningful legislation addressing health care inequities in the U.S. will require studies examining potential health disparities due to geographic location or economic status.
Careful criminals usually clean a scene, wiping away visible blood and fingerprints. However, prints made with trace amounts of blood, invisible to the naked eye, could remain. Dyes can detect these hidden prints, but the dyes don't work well on certain surfaces. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a fluorescent polymer that binds to blood in a fingerprint -- without damaging any DNA also on the surface -- to create high-contrast images.
