Metal chalcogenide supertetrahedral clusters (MCSCs) are of significance for developing crystalline porous framework materials and atomically precise cluster chemistry. Early research focused on the synthetic and structural chemistry of MCSC-based porous semiconductor materials and their applications. Recently, focus has shifted to establish the atomically precise structure-composition-property relationship of MCSCs. This review covers three decades of e?orts on MCSCs, an outlook on remaining problems to be solved and future trends is also presented.

Researchers from the Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, have developed a new method for rapid and accurate detection of viral nucleic acids - a breakthrough that can be easily adapted to detect different DNA/RNA targets in viruses like the coronavirus. The method called RApid DIgital Crispr Approach (RADICA) is four times faster and significantly less expensive than conventional polymerase chain reaction (PCR) methods.

Travelers abroad may pick up bacteria and other vectors containing genes conferring antimicrobial resistance which remain in the gut when returning to their home country, according to a study published in Genome Medicine.

Cows can pass on the hypoglycin A toxin through their milk, a study by the Martin Luther University Halle-Wittenberg (MLU) and the Leibniz Institute of Plant Biochemistry (IPB) in Toxins shows. The substance can cause severe symptoms in humans and animals. Small amounts of the toxin were detected in the raw milk of cows that grazed in a pasture exposed to sycamore maple. The team calls for further investigations to realistically assess the potential dangers.

New research identified a novel interaction between the SARS-CoV-2 spike protein and the galectin-3-binding protein (LGALS3BP) which could be a new therapeutic anti-viral target.

Antarctica has experienced significant temperature changes, especially since the last glacial period. An international collaboration including scientists from the CNRS1 has now challenged previously accepted estimates of these variations, using new measurements published on June 4, 2021 in Science. Their study highlights differences in behavior between East and West Antarctica, connected in particular to differing variations in their altitude.

A new report by the International Osteoporosis Foundation draws attention to the burden of osteoporosis and the gaps/inequalities in the provision of primary and secondary prevention of fractures due to osteoporosis across Europe. 'SCOPE 2021: a new scorecard for osteoporosis in Europe' provides findings for 27 countries of the European Union as well as Switzerland and the UK, covering key indicators for four domains: burden of disease, policy framework, service provision and service uptake.

Researchers from Osaka University discovered a novel molecular mechanism by which immune cells migrate and reach sites of infection. By studying dendritic cells, specialized immune cells that are responsible for the activation of lymph nodes during infections, they found that the lysosomal Ragulator complex is indispensable for cell migration. In the absence of the Ragulator complex in dendritic cells, mice showed an impaired immune response. This study may help develop novel therapies against autoimmune diseases.

As Australia officially enters winter, UniSA ecologists are urging coastal communities to embrace all that the season brings, including the sometimes-unwelcome deposits of brown seaweed that can accumulate on the southern shores.

A study published today in open access in the journal Environment International found high levels of lead in indigenous people in Peruvian Amazonia living near areas where oil extraction takes place.

An international coalition of eye researchers used machine learning to develop classification criteria for 25 of the most common types of uveitis, a collection of over 30 diseases characterized by inflammation inside the eye.

The recent attacks against Asian Americans, have put Asians in the U.S. in the spotlight. A new Dartmouth study explores who Asian Americans are today and the range of identities this category encompasses. Based on 2016 pre-election survey data, the study finds that Asian Americans tend to have progressive opinions towards public policy, including on healthcare, education, climate change, and racial justice, but diverge on views towards Muslim immigration.

Stuart Lindsay, a researcher at the Biodesign Institute at ASU, has been at the forefront of efforts to improve rapid DNA sequencing and has more recently applied his talents to explore the much thornier problem of sequencing protein molecules, one molecule at a time.In a new overview article, Lindsay's efforts are described along with those of international colleagues, who are applying a variety of innovative strategies for protein sequencing at the single-cell, and even single-molecule level.

A new study published in JAMA Internal Medicine finds that bots (large numbers of automated accounts controlled by single users) on Facebook spread malicious COVID-19 misinformation at far greater rates than ordinary users.

What The Study Did: Researchers analyzed conversations on public Facebook groups to explore automated misinformation.

What The Study Did: Among children with a COVID-19 diagnosis, researchers in this study examined what other conditions are common and which are associated with severe COVID-19 illness.

What The Study Did: In this study, short-term effectiveness of the first dose of the BNT162b2 (BioNTech/Pfizer) vaccine against SARS-CoV-2 infection 13 to 24 days after immunization in a real-world setting was assessed.

Physicists led by the University of Iowa report definitive evidence of how auroras are created. In experiments, the physicists demonstrated the physical mechanisms for the acceleration of electrons by Alfven waves under conditions corresponding to Earth's auroral magnetosphere. Results appear in the journal Nature Communications.

Bdelloid rotifers are multicellular animals so small you need a microscope to see them. Despite their size, they're known for being tough, capable of surviving through drying, freezing, starvation, and low oxygen. Now, researchers reporting in the journal Current Biology on June 7, 2021 have found that not only can they withstand being frozen, but they can also persist for at least 24,000 years in the Siberian permafrost and survive.

Jet packs, robot maids and flying cars were all promises for the 21st century. We got mechanized, autonomous vacuum cleaners instead. Now a team of Penn State researchers are exploring the requirements for electric vertical takeoff and landing (eVTOL) vehicles and designing and testing potential battery power sources.
