After a nuclear war, wild-catch marine fisheries will not offset the loss of food grown on land, especially if widespread overfishing continues, according to a Rutgers co-authored study. But effective pre-war fisheries management would greatly boost the oceans’ potential contribution of protein and nutrients during a global food emergency, according to the study in the journal Proceedings of the National Academy of Sciences. The study for the first time explored the effects of nuclear war on wild-catch marine fisheries.
Through large-scale profiling of protein changes in response to drug treatments in cancer cell lines, researchers at The University of Texas MD Anderson Cancer Center have generated a valuable resource to aid in predicting drug sensitivity, to understand therapeutic resistance mechanisms and to identify optimal combination treatment strategies.
COVID-19 is caused by the virus SARS-CoV-2, which is structurally similar to the viruses that cause SARS-CoV and MERS-CoV. In The Journal of Chemical Physics, scientists report molecular-level investigations of these viruses, providing a possible pathway to antiviral drugs to fight the diseases. They looked at a viral protein that plays a role in the virus’s ability to replicate and in defeating the host’s immune system, making it an attractive target for potential drug treatments.

Researchers from the National University of Singapore have identified a new avenue to maintain bone health, which opens up new and potentially more effective osteoporosis treatments.
In severe cases of COVID-19, damage can spread beyond the lungs and into other organs, such as the heart, liver, kidney and parts of the neurological system. Beyond these specific sets of organs, however, the virus seems to lack impact. Ernesto Estrada aimed to uncover an explanation as to how it is possible for these damages to propagate selectively rather than affecting the entire body. He discusses his findings in the journal Chaos.
Lawrence Livermore National Laboratory (LLNL) researchers, in collaboration with Pennsylvania State University (PSU) and Idaho National Laboratory (INL), have designed a new process, based on a naturally occurring protein, that could extract and purify rare earth elements (REE) from low-grade sources. It could offer a new avenue toward a more diversified and sustainable REE sector for the United States. The protein, lanmodulin, enables a one-step extraction and purification of (REE)s from complex metal mixtures, including electronic waste and coal byproducts.
As the COVID-19 pandemic continues to spread, many researchers are studying epidemiological models to predict its propagation. However, a mathematician and expert in complex systems decided to focus on finding targets within SARS-CoV-2 for new drugs to attack. In the journal Chaos, he discusses the dramatic increase in the sensitivity of the main protease of SARS-CoV-2 to small disturbances, which made him suspect there is a role for inhibitors to play in killing the virus.
Scientists open doors to new treatment possibilities by using a metal complex to accelerate serum albumin protein destruction with infrared laser beams
Algae in the oceans often steal genes from bacteria to gain beneficial attributes, such as the ability to tolerate stressful environments or break down carbohydrates for food, according to a Rutgers co-authored study.
The study of 23 species of brown and golden-brown algae, published in the journal Science Advances, shows for the first time that gene acquisition had a significant impact on the evolution of a massive and ancient group of algae and protists (mostly one-celled organisms including protozoa) that help form the base of oceanic food webs.
Proteins are the building blocks of life and scientists have long studied how to improve them or design new ones. Traditionally, new proteins are created by mimicking existing proteins or manually editing their amino acids. This process is time-consuming, and it is difficult to predict the impact of changing an amino acid. In APL Bioengineering, researchers explore how to create new proteins by using machine learning to translate protein structures into musical scores, presenting an unusual way to translate physics concepts across domains.
New research from the University of Notre Dame shows these silent mutations are worth a closer look.
