2021-04-21
(Press-News.org) What The Study Did: Researchers looked at whether short-term exposure to air pollution from a 2018 California wildfire was associated with changes in the number of clinic visits for eczema or itch and medications prescribed for eczema.

Authors: Maria L. Wei, M.D., Ph.D., of the University of California, San Francisco, is the corresponding author.

First of its kind study links wildfire smoke to skin disease

2021-04-21
Wildfire smoke can trigger a host of respiratory and cardiovascular symptoms, ranging from runny nose and cough to a potentially life-threatening heart attack or stroke. A new study suggests that the dangers posed by wildfire smoke may also extend to the largest organ in the human body, and our first line of defense against outside threat: the skin. During the two weeks in November 2018 when wildfire smoke from the Camp Fire choked the San Francisco Bay Area, health clinics in San Francisco saw an uptick in the number of patients visiting with concerns of eczema, also known as atopic dermatitis, and general itch, compared to the same time of the year ...

Scientists reveal origin of neuronal diversity in hypothalamus

Scientists reveal origin of neuronal diversity in hypothalamus
2021-04-21
A mechanistic understanding of brain development requires a systematic survey of neural progenitor cell types, their lineage specification and maturation of postmitotic neurons. Cumulative evidences based on single-cell transcriptomic analysis have revealed the heterogeneity of cortical neural progenitors, their temporal patterning and the developmental trajectories of excitatory and inhibitory neurons in the developing neocortex. Nevertheless, the developmental hierarchy of the hypothalamus, which contains an astounding diversity of neurons that regulate endocrine, autonomic and behavioral functions, has not been well understood. Recently, however, Prof. WU Qingfeng's ...

Review: Changing views on atherosclerosis

2021-04-21
WHO Peter Libby, MD, cardiovascular medicine specialist at Brigham and Women's Hospital and the Mallinckrodt Professor of Medicine at Harvard Medical School; author of a new review paper published in Nature. WHAT Atherosclerosis -- hardening of the arteries -- is now involved in the majority of deaths worldwide, and advances in our understanding of the biology of the disease are changing traditional views and opening up new avenues for treatment. The picture of who may be at risk for a heart attack has evolved considerably in recent decades. At one time, a heart attack might have conjured up the image of a middle-aged white man with high cholesterol and high blood pressure who smoked cigarettes. Today, traditional concepts of what contributes to risk have changed. These ...

Bistable pop-up structures inspired by origami

Bistable pop-up structures inspired by origami
2021-04-21
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. Today's inflatable structures, used for everything from field hospitals to sporting complexes, are monostable, meaning they need a constant input of pressure in order to maintain their inflated state. Lose that pressure and the structure ...

In calculating the social cost of methane, equity matters

2021-04-21
What is the cost of 1 ton of a greenhouse gas? When a climate-warming gas such as carbon dioxide or methane is emitted into the atmosphere, its impacts may be felt years and even decades into the future - in the form of rising sea levels, changes in agricultural productivity, or more extreme weather events, such as droughts, floods, and heat waves. Those impacts are quantified in a metric called the "social cost of carbon," considered a vital tool for making sound and efficient climate policies. Now a new study by a team including researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) ...

To design truly compostable plastic, scientists take cues from nature

To design truly compostable plastic, scientists take cues from nature
2021-04-21
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. Biodegradable plastic bags and containers could help, but if they're not properly sorted, they can contaminate otherwise recyclable #1 and #2 plastics. What's worse, most biodegradable plastics take months to break down, and when they finally do, they form microplastics - tiny bits of plastic that can end up in our oceans, fish, and even our bodies. Now, as reported in the journal Nature, scientists at the Department ...

Recolonization of Europe after the last ice age started earlier than previously thought

Recolonization of Europe after the last ice age started earlier than previously thought
2021-04-21
A study that appeared today on Current Biology sheds new light on the continental migrations which shaped the genetic background of all present Europeans. The research generates new ancient DNA evidence and direct dating from a fragmentary fossil mandible belonging to an individual who lived ~17,000 years ago in northeastern Italy (Riparo Tagliente, Verona). The results backdate by about 3,000 years the diffusion in Southern Europe of a genetic component linked to Eastern Europe/Western Asia previously believed to have spread westwards during later major warming shifts. "By looking into the past of this particular individual, ...

Astronomers release new all-sky map of the Milky Way's outer reaches

2021-04-21
Astronomers using data from NASA and the ESA (European Space Agency) telescopes have released a new all-sky map of the outermost region of our galaxy. Known as the galactic halo, this area lies outside the swirling spiral arms that form the Milky Way's recognizable central disk and is sparsely populated with stars. Though the halo may appear mostly empty, it is also predicted to contain a massive reservoir of dark matter, a mysterious and invisible substance thought to make up the bulk of all the mass in the universe. The data for the new map comes from ESA's Gaia mission and NASA's Near Earth Object Wide Field Infrared Survey Explorer, or NEOWISE, which operated from 2009 to 2013 under the moniker WISE. The study, led by astronomers at the Center for ...

Improved management of farmed peatlands could cut 500 million tons CO2

Improved management of farmed peatlands could cut 500 million tons CO2
2021-04-21
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. But many peatland areas have been substantially modified by human activity, including drainage for agriculture and forest plantations. This results in the ...

Bubble with titanium trigger titanic explosions

Bubble with titanium trigger titanic explosions
2021-04-21
Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode. This work is based on Chandra observations of the remains of a supernova called Cassiopeia A (Cas A), located in our galaxy about 11,000 light-years from Earth. This is one of the youngest known supernova remnants, with an age of about 350 years. For years, scientists have struggled to understand how massive stars - those with masses over about 10 times that of the Sun - explode when they run ...
