The honor of the 2020 Nobel Prize in Chemistry went to those who developed lithium-ion rechargeable batteries. These batteries have become an essential energy source for electronic devices ranging from small IT devices to electric vehicles. Tesla, a leading U.S. automaker, recently emphasized the need to establish an innovative production system and reduce battery cost. The price of batteries accounts for a large portion of electric vehicles and cost reduction is vital to popularizing them.
The development of pharmaceutical treatments is difficult -- clinicians and researchers know a certain drug can regulate particular functions, but they might not know how it actually works. Researchers at Tokyo University of Agriculture and Technology (TUAT) have developed a new, streamlined method to better understand the molecular mechanisms underpinning these interactions.
They published their approach on Dec. 17, 2020 in Organic & Biomolecular Chemistry, a journal of the U.K. Royal Society of Chemistry.
(Singapore--January 30, 2021 11:00 p.m. SPT/January 30, 2021 10:00 a.m. EST)-- Primary analysis of the Lung Cancer Mutation Consortium (LCMC) 3 study revealed that neoadjuvant atezolizumab prior to lung cancer surgery was well tolerated by patients and met its primary endpoint of 20% major pathologic response rate, according to research presented today at the International Association for the Study of Lung Cancer's World Conference on Lung Cancer.
CHICAGO (January 30, 2021) -- Select patients born with heart defects and who undergo congenital heart surgery recover with few complications and reduced opioid use when a comprehensive, evidence-based enhanced recovery after surgery (ERAS) program is used, according to research presented at the 57th Annual Meeting of The Society of Thoracic Surgeons.
CHICAGO (January 30, 2021) -- The most deadly global health crisis in a century has resulted in a substantial decline in overall heart surgery volume and an unexplained increase in deaths after coronary artery bypass grafting, according to late-breaking research presented at the 57th Annual Meeting of The Society of Thoracic Surgeons.
What if scientists knew exactly what impact the SARS-CoV-2 virus had inside our lung cells, within the first few hours of being infected? Could they use that information to find drugs that would disrupt the virus' replication process before it ever gets fully underway? The discovery that several existing FDA-approved drugs--including some originally designed to fight cancer--can stop coronavirus in its tracks indicates the answer is a resounding yes.
In northern Canada, the forest floor is carpeted with reindeer lichens. They look like a moss made of tiny gray branches, but they're stranger than that: they're composite organisms, a fungus and algae living together as one. They're a major part of reindeer diets, hence the name, and the forest depends on them to move nutrients through the ecosystem. They also, at least in parts of Quebec, are having a lot more sex than scientists expected.
Researchers at Linköping University, Sweden, have developed a proton trap that makes organic electronic ion pumps more precise when delivering drugs. The new technique may reduce drug side effects, and in the long term, ion pumps may help patients with symptoms of neurological diseases for which effective treatments are not available. The results have been published in Science Advances.
(Singapore--January 29, 2021 9:35 a.m. SPT/January 28, 2021 8:35 p.m. EST)--Two radiation oncology trials presented at the IALSC World Conference on Lung Cancer Singapore highlight how some researchers are exploring use of higher radiation boost doses to only PET-positive regions in locally-advanced non-small cell lung cancer (NSCLC). A previous large RTOG phase III trial revealed that the unform delivery of a high dose to the entire tumor led to poorer survival.
CAMBRIDGE, MA -- In many ways, our brain and our digestive tract are deeply connected. Feeling nervous may lead to physical pain in the stomach, while hunger signals from the gut make us feel irritable. Recent studies have even suggested that the bacteria living in our gut can influence some neurological diseases.
What The Study Did: This study investigated how unemployment insurance and a $600 per week federal supplement to unemployment insurance were associated with food insecurity among people in low- and middle-income households who lost jobs during the COVID-19 pandemic.
Authors: Julia Raifman, Sc.D., of the Boston University School of Public Health, is the corresponding author.

In 2017, the Nobel Prize in Physiology or Medicine went to three scientists who uncovered the molecular mechanisms that control the circadian rhythm, otherwise known as the "wake-sleep" cycle. To carry out their work, the scientists used the common fruit fly Drosophila melanogaster, making this the sixth Nobel to be awarded to research involving it.
Fruitful fruit flies
CHICAGO (January 29, 2021): Trauma patients and patients who need emergency surgery have little to no opportunity to get acquainted with the surgeon and team that will perform their operation. However, a large study has found that effective and meaningful physician communication is a more important contributor to the overall satisfaction of trauma patients and those having emergency surgery than it is for patients admitted to the hospital for medical reasons or for elective procedures.
An international team of scientists, coordinated by the Seville Institute of Biomedicine (IBiS) and the University of Seville has solved one of the hitherto unresolved enigmas of basic biology: how exactly do lipids distribute proteins within a cell? To do this, they used a new, completely innovative microscopy technology, which they applied to "mutant" cells they designed in their laboratory.
