Scientists at St. Jude Children's Research Hospital have found a link between post-cancer treatment frailty and neurocognitive decline in young adult childhood cancer survivors. A paper on this work was published today in the Journal of Clinical Oncology.
To reach the target of carbon neutral, a transition from fossil energy to renewable energy generation is indispensable. Photovoltaic technology is considered as one of the most prominent sources of renewable energy. For decades, about 90% of global solar cell market has been dominated by silicon solar cells. Although the price of silicon solar panels decreases year by year, it is a big challenge to significantly reduce its manufacturing cost further. Hence, next-generation photovoltaic technologies are in urgent need of new materials and novel techniques.
One of the major challenges in modern cancer therapy is the adaptive response of cancer cells to targeted therapies: initially, these therapies are very often effective, then adaptive resistance occurs, allowing the tumor cells to proliferate again. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. The analysis of these mechanisms is limited by the complexity of cause and effect relationships that are extremely difficult to observe in vivo in tumor samples.
Tsukuba, Japan - Rice is the world's most commonly grown and consumed crop. It also supports lives and livelihoods, especially in low- and middle-income regions. As such, methods for securing abundant and profitable rice harvests are key in global food security.
Since buildings consume 75% of electricity in the U.S., they offer great potential for saving energy and reducing the demands on our rapidly changing electric grid. But how much, where, and through which strategies could better management of building energy use actually impact the electricity system?
Aryl sulfide, an aromatic compound in which sulfur is attached to an aryl (a functional group derived from an aromatic ring), is found in biologically active materials effective against asthma, Alzheimer's disease, and cancer. As a result, chemists have shown a lot of interest in synthesizing aryl sulfides. Traditionally, carbon-sulfur (C-S) bond formation reactions between thiols and aryl electrophiles catalyzed by transition metals have been employed for aryl sulfide synthesis because of their high reliability. However, thiols have an unpleasant smell and are toxic.
Nanomaterials have been used in a variety of emerging applications, such as in targeted pharmaceuticals or to bolster other materials and products such as sensors and energy harvesting and storage devices. A team in the McKelvey School of Engineering at Washington University in St. Louis is using nanoparticles as heaters to manipulate the electrical activity of neurons in the brain and of cardiomyocytes in the heart.
Rome (Italy), July 21st, 2021 - The remarkable structural properties of the basket sponge (E. aspergillum) might seem fathoms removed from human-engineered structures. However, insights into how the organism's latticework of holes and ridges influences the hydrodynamics of seawater in its vicinity could lead to advanced designs for buildings, bridges, marine vehicles and aircraft, and anything that must respond safely to forces imposed by the flow of air or water.
It's hard to save what you can't identify. That's been a problem for the endangered salt marsh harvest mouse, which is found only in the salty, brackish waters of the San Francisco Bay area. The mouse competes for space with about eight million humans, and more than three-quarters of its habitat has been eaten by development and land conversion. That loss is expected to increase amid rising sea levels.
Conserving the population has proven tricky, in part because it looks so much like another mouse in the area--the western harvest mouse--that is abundant throughout western U.S.
Researchers from the Antimicrobial Resistance (AMR) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, alongside collaborators from Biobot Analytics, Nanyang Technological University (NTU) and Massachusetts Institute of Technology (MIT), have successfully developed an innovative, open-source molecular detection method that is able to detect and quantify the B.1.1.7 (Alpha) variant of SARS-CoV-2.
