Structural racism and lung cancer risk

JAMA Oncology

2023-11-30
(Press-News.org) About The Study: The findings of this study suggest that structural racism must be considered as a fundamental contributor to the unequal distribution of lung cancer risk factors and thus disparate lung cancer risk across different racial and ethnic groups. Additional research is needed to better identify mechanisms contributing to inequitable lung cancer risk and tailor preventive interventions. 

Authors: Sidra N. Bonner, M.D., M.P.H., M.Sc., of the University of Michigan in Ann Arbor, is the corresponding author.

Traumatic memories are represented differently than regular sad memories in the brains of people with PTSD, new research shows

Traumatic memories are represented differently than regular sad memories in the brains of people with PTSD, new research shows
2023-11-30
A new analysis of the brain activity of people with post-traumatic stress disorder (PTSD) is the first to reveal that traumatic memories are represented in the brain in an entirely different way than sad autobiographical memories. This finding supports the notion that traumatic memories in PTSD are an alternate cognitive entity that deviates from regular memory, and may provide a biological explanation for why the recall of traumatic memories often displays as intrusions that differ profoundly from “regular” negative memories for patients with PTSD. The study, ...

Study reveals distinct brain activity triggered by memories of trauma

2023-11-30
New Haven, Conn. — It is well known that people who have lived through traumatic events like sexual assault, domestic abuse, or violent combat can experience symptoms of post-traumatic stress disorder (PTSD), including terrifying flashbacks, severe anxiety, and uncontrollable thoughts about the incident. But what exactly happens in the brains of PTSD patients as they recall these traumatic events? Are they remembered the same way as, say, the loss of a beloved pet — or, for that matter, a relaxing walk on the beach? A new study co-led by Yale researchers finds that the brain activity triggered by recollections of traumatic experiences ...

Armed to the hilt: Study solves mystery behind bacteria’s extensive weaponry

2023-11-30
New study tackles the mystery of why bacteria often carry diverse ranges of weapons. The findings show that different weapons are best suited to different competition scenarios. Short-range weapons help bacteria to invade established communities; long-range weapons are useful once established. A new study led by the University of Oxford has shed light on why certain species of bacteria carry astonishing arsenals of weapons. The findings, published today in the journal Nature Ecology & Evolution, could help us to engineer microbes that can destroy deadly pathogens, reducing our reliance on antibiotics. Many species of bacteria possess ...

Gladstone team uncovers why maternal diabetes predisposes babies to heart defects

2023-11-30
SAN FRANCISCO—November 30, 2023—When women with diabetes become pregnant, they face not only the typical challenges of pregnancy and impending parenthood, but also a scary statistic: they’re five times more likely to have a baby with a congenital heart defect. Researchers at Gladstone Institutes have now discovered why that is, identifying the cells and molecules that go awry in the developing hearts of fetuses in women with diabetes. They found that a small subset of cells destined to become part of the heart’s aorta and pulmonary artery have unusually high levels of retinoic acid activity, which coaxes them to behave more like cells found ...

CityU researchers tackle a century-old teletraffic challenge to enhance medical and public service efficiency

CityU researchers tackle a century-old teletraffic challenge to enhance medical and public service efficiency
2023-11-30
Efficiently meeting the growing demand for public services in metropolitan areas has long been a persistent challenge. A research team at City University of Hong Kong (CityU) has developed a novel performance evaluation method, which marks a major breakthrough in tackling a century-old problem of evaluating blocking probabilities in queueing systems with overflow, providing ways to allocate limited resources better. With the remarkable advances in computational efficiency and accuracy, the method has great potential to optimise the performance of numerous telecommunication networks and even medical care systems, ultimately enhancing ...

Bringing asteroids to class: COSPAR joins new Erasmus+ program

Bringing asteroids to class: COSPAR  joins new Erasmus+ program
2023-11-30
COSPAR and the Erasmus+ Education Programme COSPAR’s participation in Erasmus+ programmes is part of the COSPAR Panel on Education’s new approach to its mission of developing “means and media to encourage and spread space-related education”. The StudenTs As plaNetary Defenders (StAnD) project aims to engage primary and secondary school students in the subject of asteroids, meteors, and planetary defence. The 36-month StudenTs As plaNetary Defenders (StAnD) programme brings asteroids, comets, meteors and meteorites to the classroom using carefully prepared activities and experiments. The programme includes the installation of meteor detection cameras in participating ...

Developing a superbase-comparable BaTiO3−xNy oxynitride catalyst

Developing a superbase-comparable BaTiO3−xNy oxynitride catalyst
2023-11-30
Basic oxide catalysts contain oxygen ions with unpaired electrons that can be shared with other species to facilitate a chemical reaction. These catalysts are widely used in the synthesis of chemicals, pharmaceuticals, and petrochemicals. There have been efforts to improve the catalytic power of these catalysts by improving their basicity or the ability to donate electrons or accept hydrogen ions. Various strategies include doping the catalyst with highly electronegative cations such as alkali metals, substituting oxide ions ...

Hurricanes boost cone production in longleaf pine

Hurricanes boost cone production in longleaf pine
2023-11-30
New research on tree reproduction is helping solve a puzzle that has stumped tree scientists for decades. Many tree species exhibit a reproductive phenomenon known as “masting”, where individual trees have very low seed production in most years followed by a sudden burst of seed production that is synchronized over large parts of its range. The reason for this coordinated reproduction within a species is unclear.  A new study by scientists at The Jones Center at Ichauway and the USDA Forest Service Southern Research Station showed ...

Scientists uncover how fermented-food bacteria can guard against depression, anxiety

Scientists uncover how fermented-food bacteria can guard against depression, anxiety
2023-11-30
University of Virginia School of Medicine researchers have discovered how Lactobacillus, a bacterium found in fermented foods and yogurt, helps the body manage stress and may help prevent depression and anxiety. The findings open the door to new therapies to treat anxiety, depression and other mental-health conditions. The new research from UVA’s Alban Gaultier, Ph.D., and collaborators is notable because it pinpoints the role of Lactobacillus, separating it out from all the other microorganisms that naturally live in and on our bodies. These organisms are collectively known as the microbiota, and scientists have increasingly ...

Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables

Broadband buzz: Periodical cicadas chorus measured with fiber optic cables
2023-11-30
Annapolis, MD; November 30, 2023—Hung from a common utility pole, a fiber optic cable—the kind bringing high-speed internet to more and more American households—can be turned into a sensor to detect temperature changes, vibrations, and even sound, through an emerging technology called distributed fiber optic sensing. However, as NEC Labs America photonics researcher Sarper Ozharar, Ph.D., explains, acoustic sensing in fiber optic cables "is limited to only nearby sound sources or very loud events, such as emergency vehicles, car alarms, or cicada emergences." Cicadas? Indeed, periodical cicadas—the ...
