Engineering nanobodies as lifesavers when SARS-CoV-2 variants attack
Scientists are pursuing a new strategy in the protracted fight against the SARS-CoV-2 virus by engineering nanobodies that can neutralize virus variants in two different ways.

A warming climate and intensifying land use increase mercury content in fish
Recent studies show that, in the future, the mercury concentration of fish in Finnish Lapland can shift closer to the level found in lakes located below the Arctic Circle. According to researchers, mercury content should be increasingly carefully investigated and monitored in fish and food webs, as the climate and land use change.

Four-component, and asymmetric radical 1,4-oxy-trifluoromethylation to olefins
Asymmetric three-component 1,2-oxytrifluoromethylations of styrenes were explored by using N-oxyphthalimide (NOPI) as the resulting benzylic radical anchor after cross-coupling by a CF3 radical under the catalyses of chiral N-salicylidene-derived oxovanadium(V) complexes. Unprecedented, four-component, and asymmetric radical 1,4-oxy-trifluoromethylation to olefins was also achieved. DFT calculations were performed to explain the enantioselectivity. The enantioselectivity profile was dominated by several noncovalent interactions between the intermediary vanadium(NOPI) complex and the resulting benzylic radical.

Analysing volcanoes to predict their awakening
A team led by UNIGE has reviewed the literature on the internal and external mechanisms that lead to a volcanic eruption. Analyzing the thermo-mechanics of deep volcanic processes and magma propagation to the surface, together with magma chemistry, the geologists determined that most of the magma rising from depth actually does not cause a volcanic eruption. They also show that older volcanoes tend to produce less frequent, but larger and more dangerous eruptions.

Multiple long-term physical health problems increase risk of depression later in life
Middle-aged people in the UK with at least two long-term physical health conditions are at a greater risk of developing depression or anxiety later in life compared to those with none or only one long-term physical health condition, according to new research from King's College London.

No northern escape route for Florida's coral reefs
Warming seas are driving many species of marine life to shift their geographic ranges out of the tropics to higher latitudes where the water is cooler. Florida's reefs will not be able to make that northward move, however, as they will be caught between intolerably hot tropical waters and increasingly frequent water-cooling cold snaps, according to new findings from Florida Institute of Technology, the U.S. Geological Survey, and several other institutions to be published June 22 in Nature's Scientific Reports.

Aviation's contribution to cutting climate change likely to be small
Although the emissions targets for aviation are in line with the overall goals of the Paris Agreement, there is a high likelihood that the climate impact of aviation will not meet these goals, according to a new study.

Future wood use assures long-term climate benefit from commercial forests
A new study published in Nature Communications demonstrates the important role that planting new commercial forests could play in the fight against climate change by including new accounting of greenhouse gas (GHG) mitigation achieved from future use of harvested wood. The study applied a novel, time-dependent assessment to capture the complex dynamics of carbon uptake, storage and partial eventual release back to the atmosphere, alongside product and energy substitution by wood products, over a 100 years.

More than 6% of Europeans suffer from depression
A study in 27 European countries puts the prevalence of depression at 6.4% of the population. The work, published in The Lancet Public Health, analyzed data from the European Health Interview Survey, which includes responses from more than 250,000 people. The incidence is higher in women at 7.7%, while in men it is 4.9%. Strong differences are seen between countries, with higher rates in more economically developed states.

Ben-Gurion U. develop new measure continuous traumatic stress impact
"Current scales assess the more commonly known effects of exposure to traumatic stress, mainly post-traumatic stress disorder (PTSD). This limits patient assessment and may lead to misdiagnoses and ineffective treatment," says Dr. Goral. "The research was conducted to address this gap by developing a validated, comprehensive assessment tool, the Continuous Traumatic Stress Response (CTSR) Scale."

UBC Sauder study shows cigarette tax hikes can help boost bigger brands, hurt consumers
For decades, governments and health authorities have tried to steer people away from "vice" products such as tobacco through counter-marketing measures such as tax increases, but according to a new study from the UBC Sauder School of Business, they can help people quit -- but how much they help, and who pays the price, varies significantly.

Bee-impersonating flies show pollinator potential
An observational study found that out of more than 2,400 pollinator visits to flowers at urban and rural farms in in Western Washington about 35% of were made by flies -- most of which were the black-and-yellow-striped syrphid flies. For a few plants, including peas, kale and lilies, flies were the only pollinators observed. Bees still made the majority, about 61%, of floral visits, but the rest were made by other insects and spiders.

12,000 scientific articles a year -- can they all be wrong?
X-ray photoelectron spectroscopy (XPS) is often used to determine the chemical composition of materials. It was developed in the 1960s and is accepted as a standard method in materials science. Researchers at Linköping University, Sweden, however, have shown that the method is often used erroneously.

Twin study is first to reveal genetic risk factors for PTSD and migraine
While scientists have known that PTSD and migraine often co-occur, no-one had studied this link, before now. A new study by the open access publisher Frontiers on identical twins investigates the genetic basis for both migraine and PTSD. It reveals epigenetic risk factors that are shared by PTSD and migraine, suggesting that similar environmental risk factors are at play in both conditions. The findings could help researchers to develop new treatments.
