What The Study Did: Symptoms of posttraumatic stress disorder, depression, anxiety and insomnia among health care workers in Italy during the COVID-19 pandemic are reported in this observational study.
Authors: Rodolfo Rossi, M.D., of the University of Rome Tor Vergata in Italy, is the corresponding author.

Many insects process visual information to make decisions about controlling their flying skills and movements- flies must decide whether to pursue prey, avoid a predator, maintain their flight trajectory or land based on their perceptions.
Why is understanding this process important? We move every day and perceive the world differently as a result.
For example, if you're driving on the freeway your visual system adapts to high speed, and after a while 50km/h feels very slow. In contrast, when running or walking you are able to maintain a more steady velocity.
Users of high-potency cannabis are four times more likely to report associated problems, and twice as likely to report anxiety disorder, than users of lower-potency strains, according to new research from the University of Bristol.
Published today on JAMA Psychiatry the research uses data from Children of the 90s, a long-term health study that recruited more than 14,000 pregnant women and their babies born in and around Bristol in the early 1990s and has been following their health and development ever since.
The Near East was a crossroad for the ancient world's greatest civilizations, and invasions over centuries caused enormous changes in cultures, religions and languages. However, a new study of the DNA of ancient skeletons spanning 4,000 years has revealed that most of these changes had no lasting effect on the genetics of the local population of Beirut.
CAMBRIDGE, MA -- Many proteins are useful as drugs for disorders such as diabetes, cancer, and arthritis. Synthesizing artificial versions of these proteins is a time-consuming process that requires genetically engineering microbes or other cells to produce the desired protein.
New research on one history's most important trading hubs provides some of the earliest genetic glimpses at the movement and interactions of populations that lived in parts of Western Asia between two major events in human history: the origins of agriculture and the rise of some of the world's first cities.
The work reveals how a high level of human movement in the region not only led to the spread of ideas and material culture but to a more genetically connected society well before the rise of cities, not the other way around, as previously thought.
The existence of a planet the size of Earth around the closest star in the solar system, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva (UNIGE). The results, which you can read all about in the journal Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 earth masses and is located in the habitable zone of its star, which it orbits in 11.2 days.
Major life events such as marriage, death of a loved one or bankruptcy all affect our wellbeing. Now, for the first time, researchers have compared the differing impact of these events on the happiness and life satisfaction and how long that impact lasts.
The study examined 18 major life events, and how they affected a sample of 14,000 Australians between 2002 and 2016. The data was taken from the HILDA survey, which examines the social, health and economic conditions of Australian households using face-to-face interviews and self-completion questionnaires.
In proteins, amino acids are held together by amide bonds. These bonds are long-lived and are robust against changes in temperature, acidity or alkalinity. Certain medicines make use of reactions involving amide bonds, but the bonds are so strong they actually slow down reactions, impeding the effectiveness of the medicines. Researchers devised a way to modify amide bonds with a twist to their chemical structure that speeds up reactions by 14 times.
If you make your bio-product 100% sustainable it may be way too expensive to produce. If you make it less environmentally friendly, you may, at some point, end up having a feasible product that can compete on market terms. But is it still sustainable? This balancing game is very real to lots of companies producing bio-chemicals; that is chemicals produced from biomass instead of petroleum which chemicals are conventionally made from.
New research provides insight into how housing prices and neighborhood values have become polarized in some urban areas, with the rich getting richer and the poor becoming poorer.
The results of the study, done in Columbus, Ohio, suggest that some of the factors long thought to impact neighborhood values - such as the distance to downtown, nearby highways, or attractions such as city parks - no longer matter much to changing housing prices in an area.
The first ever specimen of a pterodactyl, more commonly found in China and Brazil, has been found in the United Kingdom.
A fossil hunter recently discovered a peculiar shaped fragment of fossil bone while out walking his dog in Sandown Bay on the Isle of Wight.
Not sure what it was, he passed it to University of Portsmouth Palaeontology student Megan Jacobs, who thought it might be the jaw bone from a pterodactyl. Further research proved she was right.
An international research team has for the first time obtained the structure of the light-sensitive sodium-pumping KR2 protein in its active state. The discovery provides a description of the mechanism behind the light-driven sodium ion transfer across the cell membrane. The paper came out in Nature Communications.
A study of the methodology for credibility assessment of historical global LUCC datasets has been published in SCIENCE CHINA Earth Sciences. The corresponding author is professor Fang Xiuqi of Beijing Normal University.
A team around Ron Pinhasi at the University of Vienna carried out a detailed analysis of ancient DNA of individuals from the Bronze Age Southern Levant known as 'Canaanites', to provide insights on the historical and demographic events that shaped the populations of that time and area. The scientists aimed at answering three basic questions: How genetically homogenous were the people from the Bronze Age Southern Levant, what were their plausible origins with respect to earlier peoples, and how much change in ancestry has there been in the region since the Bronze Age?
