In a study published in Nature Communications, a research team led by CHEN Tao from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences discovered the unique defect properties of low-dimensional materials particularly Sb2S3 through building the bridge between the deep-level defects of Sb2S3 and anion/cation ratio.

Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides such as lindane or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Empa and Eawag used these bacteria to generate enzymes that can break down these dangerous chemicals.

Russian scientists have developed a simple and easily reproducible cell labeling system that allows tracking the behavior and movement of individual cells when solving problems that require maximum accuracy.

Researchers at the University of Gothenburg have observed the absorption of a single electron by a levitated droplet with such a magnification that it is visible with the naked eye and can even be measured with a normal millimeter scaled ruler.

Scientists find the impact of anthropogenic forcing on drought risk over Southeast Asia has already exceeded internal climate variability in the late 20th and they call for actions to reduce anthropogenic aerosol loading and greenhouses gases emissions.

A new species of nematode (roundworm), named Cryptaphelenchus abietis, was isolated from bark beetles from a dead log collected in Nagano, Japan. The females of this newly described species can be identified based on the size of the post-uterine sac and the conical tail with an elongate posterior part. The males have seven genital papillae and a narrow bursal flap-like extension. The culturability of this species means it may be useful in further nematode research.

Researchers at the Cluster of Excellence CIBSS - Centre for Integrative Biological Signalling Studies develop technology to introduce genes into single cells in a targeted manner.

Researchers from the Hospital del Mar and Pompeu Fabra University have confirmed that messenger RNA vaccines pre-prepared in syringes for their administration can be transported by road for up to three hours. The researchers have conducted stress tests on syringes pre-prepared for administering the Pfizer BioNTech and Moderna vaccines, and have found that the vector these vaccines use, the messenger RNA, maintains its integrity despite being subjected to movement.

The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs was published in Astrophysical Journal Letters on June 9, 2021, are based on 40 orbits of NASA's Hubble Space Telescope, with imaging by the Advanced Camera for Surveys and a "tip of the red giant branch" (TRGB) analysis.

Professor DENG Tao from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences and his collaborators from China and the U.S.A. recently reported a new species Paraceratherium linxiaense sp. nov., which offers important clues to the dispersal of giant rhinos across Asia.

Research published today in the journal Cell is the first to establish how a specific gut bacterium, activated Bifidobacterium infantis EVC001 (B. infantis), influences immune system development in infants, and could thereby reduce the risk of allergic and autoimmune conditions later in life.

Many diseases caused by a dysregulated immune system, such as allergies, asthma and autoimmunity, can be traced back to events in the first few months after birth. To date, the mechanisms behind the development of the immune system have not been fully understood. Now, researchers at Karolinska Institutet show a connection between breast milk, beneficial gut bacteria and the development of the immune system. The study is published in Cell.

- POLQ inhibitors identified as a new class of targeted drugs- New drug class can kill cancer cells with BRCA gene mutations and those that have become resistant to PARP inhibitors- POLQ inhibitor drug soon to be tested in clinical trials

The 'Xpert Ultra' molecular test has a greater capacity than its predecessor ('Xpert MTB/RIF') in detecting tuberculosis cases, either passively (i.e. people who attend the hospital with disease symptoms) or actively (searching for possible cases in the community among contacts of cases).

What The Study Did: Researchers estimated survival and other outcomes of very preterm infants in China discharged against medical advice from neonatal intensive care units before complete care can be provided compared with infants who receive full intensive care treatment.

What The Study Did: In this survey study, COVID-19 was associated with large reductions in economic security among women at high risk of HIV infection in Kenya. However, shifts in sexual behavior may have temporarily decreased their risk of HIV infection.

What The Study Did: This study examined whether mandatory daily employee symptom data collection can be used as an early alert surveillance system to estimate COVID-19 hospitalizations in communities where employees live.

What The Study Did: Researchers evaluated the association of convalescent plasma treatment with 30-day mortality in hospitalized adults with hematologic (blood) cancers and COVID-19.

What The Study Did: The findings of this study suggest that the increased mortality among Black patients hospitalized with COVID-19 is associated with the hospitals at which Black patients disproportionately received care.

If Black patients were admitted to the same hospitals that serve a majority of White patients, researchers showed that their risk of death would drop by 10 percent.
