2021-01-04
(Press-News.org) What The Study Did: The findings of a survey study using data from California suggests the COVID-19 pandemic was associated with increases in self-reported worry about violence for oneself and others, increased firearm acquisition and changes in firearm storage practices.

Authors: Nicole Kravitz-Wirtz, Ph.D., M.P.H., University of California Firearm Violence Research Center and Violence Prevention Research Program, Department of Emergency Medicine, University of California Davis School of Medicine in Sacramento, is the corresponding author.

Chemists succeed in synthesis of aminoalcohols by utilizing light

Chemists succeed in synthesis of aminoalcohols by utilizing light
2021-01-04
Whether in beta-blockers to treat high blood pressure or in natural products: So-called vicinal aminoalcohols are high-quality organic compounds that are found in many everyday products. However, their production is difficult. For a long time, chemists are trying to develop efficient methods of synthesizing them. In their recent study published in the journal Nature Catalysis, scientists led by Prof. Dr. Frank Glorius of Münster University have found a solution for the production of a special variant of aminoalcohols. "The new method helps to study the properties of the substance and to find applications for these ...

Super surfaces

Super surfaces
2021-01-04
Assembling tiny chips into unique programmable surfaces, Princeton researchers have created a key component toward unlocking a communications band that promises to dramatically increase the amount data wireless systems can transmit. The programmable surface, called a metasurface, allows engineers to control and focus transmissions in the terahertz band of the electromagnetic spectrum. Terahertz, a frequency range located between microwaves and infrared light, can transit much more data than current, radio-based wireless systems. With fifth generation (5G) communications systems offering speeds 10 to 100 times faster than the previous generation, demand for bandwidth is ever increasing. Facing the emergence of technologies such as self-driving cars and augmented reality ...

Changes in abortion in Texas following executive order ban during pandemic

Astronomers agree: Universe is nearly 14 billion years old

2021-01-04
ITHACA, N.Y. - From an observatory high above Chile's Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old - give or take 40 million years. A Cornell University researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community. The new estimate, using data gathered at the National Science Foundation's Atacama Cosmology Telescope (ACT), matches the one provided by the standard ...

Prediabetes subtypes identified

Prediabetes subtypes identified
2021-01-04
All prediabetes is not the same: in people in the preliminary stages of type 2 diabetes, there are six clearly distinguishable subtypes, which differ in the development of the disease, diabetes risk, and the development of secondary diseases. This is shown in a study by the Institute for Diabetes Research and Metabolic Diseases (IDM) of Helmholtz Zentrum München at the University of Tübingen, Tübingen University Hospital and the German Center for Diabetes Research (DZD). The results have now been published in Nature Medicine. The new classification can help in the future to prevent the manifestation of diabetes ...

Severe sepsis predicted by common protein

2021-01-04
A sugar-binding protein could fuel terrible inflammation and worsen sepsis, a disease that kills more than 270,000 people every year in the US alone, reports a team of researchers led by UConn Health in the 4 January issue of Nature Immunology. Sepsis is caused mostly by bacterial infections. The immune system runs out of controls and triggers a cytokine storm, a condition in which inflammation-causing proteins flood the blood. Organs may break down, and death often follows.  Other diseases can also cause cytokine storms; medical historians believe cytokine storms were behind the lethality of the ...

Why do males have to wait for 'round 2'? The reason may be different from what we think

2021-01-04
If you type into a search engine - "why do men have to wait before having sex again?" - you will very quickly come across Prolactin. This little hormone is thought to be involved in hundreds of physiological processes in the body. Among them is the male post-ejaculatory refractory period. This period begins when a male ejaculates and ends when he recovers his sexual capacity. If you search a bit more, you'll see that this theory has even led to the development of so called "treatments". These promise to shorten the length of a person's refractory period by reducing their body's prolactin levels. Well, here is some bad news for anyone who has bought any such merchandise. A new study in mice by scientists at the Champalimaud Centre for the Unknown ...

New clues on why pregnancy may increase risk of organ transplant rejection

2021-01-04
A research study at the University of Chicago has found that in pregnancy, while the T cell response to a fetus becomes tolerant to allow for successful pregnancy, the part of the immune system that produces antibodies (known as the humoral response) becomes sensitized, creating memory B cells that can later contribute to the rejection of a transplanted organ. The results help to clarify why it is that the immune system can tolerate a fetus during pregnancy, but later may be more likely to become sensitized to and reject an organ transplant. The study was published on January 4, 2021 in the END ...

First glimpse of polarons forming in a promising next-gen energy material

First glimpse of polarons forming in a promising next-gen energy material
2021-01-04
Polarons are fleeting distortions in a material's atomic lattice that form around a moving electron in a few trillionths of a second, then quickly disappear. As ephemeral as they are, they affect a material's behavior, and may even be the reason that solar cells made with lead hybrid perovskites achieve extraordinarily high efficiencies in the lab. Now scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have used the lab's X-ray laser to watch and directly measure the formation of polarons for the first time. They reported their findings in Nature ...
