Washington, DC-- Aerosol emissions from burning coal and wood are dangerous to human health, but it turns out that by cooling the Earth they also diminish global economic inequality, according to a new study by Carnegie's Yixuan Zheng, Geeta Persad, and Ken Caldeira, along with UC Irvine's Steven Davis. Their findings are published by Nature Climate Change.
Many younger Americans are aware of new products that heat tobacco to produce a breathable aerosol, and individuals who use other tobacco products are those most likely to use them, according to a new RAND Corporation study.
About 12% of the young adults surveyed were aware of heated tobacco products and 5% reported using the products at some point in their life. The devices heat -- but do not burn -- tobacco to produce a nicotine-containing aerosol that is inhaled, similar to what occurs in smoking cigarettes or vaping e-cigarettes.
The terminology humans have conceived to explain and study our own brain may be mis-aligned with how these constructs are actually represented in nature. For example, in many human societies, when a baby is born either a "male" or a "female" box is checked on the birth certificate. Reality, however, may be less black and white. In fact, the assumption of dichotomic differences between only two sex/gender categories may be at odds with our endeavours that try to carve nature at its joints.
A new study by the University of Houston Institute for Research on Women, Gender & Sexuality (IRWGS) reports that women lag far behind men on multiple fronts in Harris County. Women are almost 50% more likely to live in poverty than men and the wage gap for men and women by race and ethnicity is considerably greater here than nationally.
A healthy diet is essential to living well, but as we age, should we change what we eat?
UTS research fellow Dr Luna Xu has studied data from 139,000 older Australians and found strong links between certain food groups, memory loss and comorbid heart disease or diabetes.
Dr Xu found high consumption of fruit and vegetables was linked to lowered odds of memory loss and its comorbid heart disease. High consumption of protein-rich foods was associated with a better memory.
Researchers in Japan have identified a new quality control system that allows cells to remove damaged and potentially toxic proteins from their surroundings. The study, which will be published February 18 in the Journal of Cell Biology, finds that the Clusterin protein and heparan sulfate proteoglycans combine to bring misfolded proteins into cells for degradation. The findings may lead to new therapeutic targets for neurodegenerative disorders, including Alzheimer’s disease.
The accumulation of aberrant proteins in the body will cause various neurodegenerative diseases. Amyloid β, one of these aberrant proteins, is a known risk factor for Alzheimer's disease. Eisuke Itakura, an assistant professor at Chiba University, says, "Human cells have functions for maintaining homeostasis. Scientists are now actively studying the typical intracellular protein degradation systems by autophagy and proteasome, but our knowledge of how cells act on aberrant external substances is still limited."
Early exposure to household cleaning products is associated with asthma and wheeze in young children
Early exposure of babies to household cleaning products is associated with the development of childhood asthma and wheeze by age 3 years, according to new research in CMAJ (Canadian Medical Association Journal).
The first articulated Neanderthal skeleton to come out of the ground for over 20 years has been unearthed at one of the most important sites of mid-20th century archaeology: Shanidar Cave, in the foothills of Iraqi Kurdistan.
Researchers say the new find offers an unparalleled opportunity to investigate the "mortuary practices" of this lost species using the latest technologies.
Shanidar Cave was excavated in the 1950s, when archaeologist Ralph Solecki uncovered partial remains of ten Neanderthal men, women and children.
CINCINNATI - The continuing epidemic of pre-term births includes this stark reality: tiny, fragile babies are born with underdeveloped lungs and prone to lifelong respiratory infections and related chronic illnesses.
WASHINGTON, February 18, 2020 -- People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to manipulate soft tissues. Astronauts are also hampered by heavy spacesuits and find it difficult to work with equipment while wearing heavy gloves.
Bethesda, Maryland (Feb. 18, 2020) - Patients at average risk of colorectal cancer who have a normal colonoscopy do not need to repeat screening for 10 years. It is common for polyps to be removed and tested during a colonoscopy, but the amount and size of polyps removed will change the patient's follow-up screening schedule. In two new publications from the U.S.
BEER-SHEVA, ISRAEL...February 18, 2020 - Researchers from Ben-Gurion University of the Negev's (BGU) Cyber Security Research Center have found that they can cause the autopilot on an autonomous vehicle to erroneously apply its brakes in response to "phantom" images projected on a road or billboard.
New research from the CHILD Cohort Study shows that frequent exposure to common household cleaning products can increase a child's risk of developing asthma.
Asthma is the most common chronic childhood disease and is the primary reason why children miss school or end up in hospital.
The study was published today in the Canadian Medical Association Journal. It found that young infants (birth to three months) living in homes where household cleaning products were used frequently were more likely to develop childhood wheeze and asthma by three years of age.
The origin of an understudied hybrid population of poisonous frogs--highly endangered colorful animals that live deep in the Colombian jungle--is the result of natural breeding and not caused by wildlife traffickers moving them, a University of Saskatchewan (USask) study shows.
