An accurate, non-invasive, and low-cost method of testing for COVID-19 using samples taken from the screens of mobile phones has been developed by a team led by UCL researchers at Diagnosis Biotech.

Pioneering research has shown marine ecosystems can start working again, providing important functions for humans, after being wiped out much sooner than their return to peak biodiversity.

A paper published in the prestigious journal Nature Medicine on long-COVID, describes persistent symptoms six months after acute COVID-19, even in young home isolated people. The most common symptoms were loss of smell and/or taste, fatigue, shortness of breath, impaired concentration, and memory problems.

Communication is crucial for elephants that live in complex multi-tiered social systems. Apart from their iconic trumpets uttered through the trunk, Asian elephants also produce species-specific squeaks by buzzing their lips. This demonstrates once again the elephant's flexibility in sound production. These results are presented in a publication in BMC Biology by behavioral biologist Veronika Beeck from the University of Vienna and colleagues.

A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 years old, more than what was thought to date.

On June 23, 2021, China is launching EarthLab in Beijing to better research how the spheres interact and impact the planet.

Organic solar elements with the self-assembling molecular-thin layer (SAM) of hole-transporting material, the technology, which was used in producing a record-breaking tandem solar cell, achieved 18.4 power conversion efficiency. The invention of Lithuanian chemists working at Kaunas University of Technology (KTU), commercialized by several global companies proved versatile and applicable to different solar technologies.

A new paper based on a literature review and a participatory process identifies principles and indicators for healthy urban design.

Research Associate Artyom Gusarov studied a vast array of erosion data to make a general takeaway that soil erosion and river sediment load in the aforementioned region has significantly decreased throughout the post-Soviet period.

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth. The study is published today in Monthly Notices of the Royal Astronomical Society.

Scientists revealed the mechanism underlying the formation of the first carbon-carbon (C-C) bond formation during the methanol-to-olefins (MTO) process.

Researchers at the University of North Carolina at Chapel Hill have uncovered a mechanism that activates specific genes, leading to the development of cancers. They showed that a mutation that fuses two unrelated genes can promote a process similar to that observed when oil and water are mixed but do not blend together. The process, called liquid-liquid phase separation, can promote cancers such as acute leukemias.

Migratory birds carry most seeds in the wrong direction to help plants cope with climate change, new research shows.

What The Study Did: Researchers examined family voucher-based kidney donations and the capability of voucher redemption to provide timely kidney transplants.

What The Study Did: The hours worked and patterns of work activities among U.S. physicians before and during the COVID-19 pandemic were examined in this study.

What The Study Did: Researchers investigated the association between counties that adopted state mask mandates in Kansas with COVID-19 cases, hospitalizations and deaths.

Skin problems after a first mRNA COVID-19 vaccine dose occurred in 1.9% of surveyed employees from hospital system Mass General Brigham. Among employees who experienced a skin reaction to the first dose, 83% had no recurrence of symptoms following the second dose.

What The Study Did: Hospital employees were surveyed about symptoms such as a rash, itching, hives or swelling around the face after receiving a messenger RNA COVID-19 vaccine.

Scientists at Cornell University and the American Museum of Natural History have identified 2,034 nearby star-systems - within the small cosmic distance of 326 light-years - that could find Earth merely by watching our pale blue dot cross our sun.

Researchers rescued mice from early death caused by a muscle-weakening disease with an antibody treatment.
