Divalent samarium compounds are important reagents for reductive transformations in organic chemistry. However, currently, a high amount of this reagent is required in most reactions, and it also necessitates the use of harmful chemicals. To address this issue, researchers have developed a visible-light-antenna ligand that coordinates with stable trivalent samarium compounds, which, upon exposure to visible light, are reduced to divalent samarium, enabling milder conditions and smaller amounts of samarium...

Can an immunoassay be created and selectively detect a virus in under 5 minutes? In a new study, researchers report that it can be done using a low-power laser like a laser pointer with a little liquid sample like a sesame seed. Read more ›

Linnaeus collected 643 different plant species that were then fed to horses, cows, pigs, sheep and goats. The results were carefully compiled but not analyzed until now, 275 years later. Read more ›

A new study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of metatranscriptomic data released by the Chinese Center for Disease Control and Prevention (CDC). The data come from more than 800 samples collected in and around the Huanan Seafood Wholesale market beginning... Read more ›

Ice may look safe for a game of pick-up hockey on the lake, but as a new study has found, looks can be deceiving. Warming winters are not only affecting ice thickness and timing -- when a lake freezes and thaws -- but also quality, making it potentially unstable and unsafe. The problem, say researchers, is that the unpredictable and warmer winter weather is creating thinner layers of black ice... Read more ›

Modern integrated microelectronic devices are often poorly repairable and difficult to recycle. Debondable adhesives play a key role in the transition to a circular economy with sustainable resources, less waste, and intelligent repair/recycling strategies. A research team has now introduced a method for making adhesives that can be deactivated 'on command'. Read more ›

Ancient DNA has provided spectacular insights into human history, particularly in Europe and Asia, where researchers have reconstructed the genomes of thousands of people. However, fewer than two dozen ancient genomes have been recovered from southern Africa -- specifically Botswana, South Africa and Zambia -- which has some of the world's earliest evidence of modern humans, with the oldest genomes dating back around 2,000 years.

Thermoelectric devices are devices that can convert heat into electrical energy. Researchers have now developed a thermoelectric device composed of organic materials that can generate electricity from ambient temperature alone. The device is made from copper phthalocyanine and copper hexadecafluoro phthalocyanine as charge transfer materials and was combined with fullerenes and BCP as electron transport layers. Read more ›

Researchers have developed a model that uses gene activity to predict when Somei Yoshino cherry tree buds awake from dormancy. Their findings could not only help improve the accuracy of flowering forecasts, but also highlight the potential of climate change to threaten flowering in Japan's southern region. Read more ›

Researchers have developed an innovative technique to rejuvenate aged oocytes, or immature egg cells, to boost their quality, paving the way for improved outcomes for in-vitro fertilization. This groundbreaking approach involves constructing hybrid ovarian follicles by transplanting aged oocytes into a young follicular environment to partially restore their reproductive potential.

Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases from mothers to human children. Read more ›

Researchers have found evidence that low oxygen levels in tumors could actually enhance some of the body's immune responses against cancer, in contrast with the general paradigm that hypoxia exclusively helps cancer progression. Their findings identified a macrophage subpopulation displaying more potent immune responses under low oxygen concentrations in tumors. Read more ›

A research team has discovered a mechanism in which blood stem cells respond to acute, severe anemia, through lipoprotein metabolism modification. It has been known how immediate erythroid precursors respond under acute anemic conditions, however, whether and how more immature stem cells react remained unknown. The outcome of this research is expected to contribute to the development of novel therapies for treating severe anemia patients who do not respond to... Read more ›

A new way of making ammonia by harnessing the unique power of liquid metal could lead to significant cuts in carbon emissions caused by production of the widely-used chemical. Ammonia is used in fertilizer to grow much of our food, but also plays a role in clean energy as a carrier to safely transport hydrogen. Read more ›

Lavas from hotspots - -whether erupting in Hawaii, Samoa or Iceland -- likely originate from a worldwide, uniform reservoir in Earth's mantle, according to an evaluation of volcanic hotspots. Read more ›

Rising temperatures are thought to reduce the number of ice crystals in clouds, leading to the formation of liquid-dominated clouds. However, a new study has found that Arctic warming is causing an increase in the emission of natural aerosols from snow/ice-free barren and vegetated areas in the Arctic. These aerosols can encourage ice crystal formation in mixed-phase clouds, potentially affecting cloud composition and the Arctic climate. Read more ›

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research shows that this part of the brain also plays a role in complex cognitive tasks like visual categorization and decision making. Read more ›
