A protein complex from plant stem cells regulates their division and response to stress

Eurekalert - Jul 06 2021 - 00:07
A team led by researchers from Barcelona has discovered that two proteins, which are involved in the control of stem cells' division in plant roots, need each other for these cells to function properly. The study combines experimental work with plants and mathematical modelling.The mechanism provides knowledge that could be useful, for agriculture and for the design of efficient strategies in medicine and cosmetics that slow down cellular aging.

High-throughput metabolic profiling of single cells

Eurekalert - Jul 06 2021 - 00:07
Scientists from the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Center (DKFZ) have presented a new method for generating metabolic profiles of individual cells. The method, which combines fluorescence microscopy and a specific form of mass spectroscopy, can analyze over a hundred metabolites and lipids from more than a thousand individual cells per hour. Researchers expect the method to better answer a variety of biomedical questions in the future.

SwRI-led team addresses mystery of heavy elements in galactic cosmic rays

Eurekalert - Jul 06 2021 - 00:07
Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving energetic particles, mostly hydrogen ions called protons, the lightest and most abundant elements in the universe. Scientists have long debated how trace amounts of heavy ions in GCRs are accelerated.

Falling in line: The simple design and control of MOF electric flow

Eurekalert - Jul 06 2021 - 00:07
Using epitaxial growth approach, researchers address the electrical conductivity problem of thin film materials by realizing a highly conductive in-plane orientation of a metal-organic framework. Furthermore, they show that it is possible to fabricate oriented thin film patterns by integration with UV lithography technology.

New study presents transformative metasurface based on zerogap embedded template

Eurekalert - Jul 06 2021 - 00:07
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has developed a new technique of predefining the crack pattern on a flexible substrate by a sequential deposition of metallic layers which leads to a formation of a zerogap between the adjacent lateral patterns.

SARS-CoV-2 encoded miRNA is a biomarker for stratification of severe patients

Eurekalert - Jul 06 2021 - 00:07
The multi-centre study identified a microRNA-like small RNA encoded by SARS-CoV-2 in the serum of COVID-19 patients, which can be developed as a non-invasive biomarker for stratification of severe patients from mild/moderate ones and for identification of high-risk individuals before clinical manifestation of severe symptoms. This biomarker ensures proper allocation of patients to different levels of medical facilities and allows more effective control of the pandemic and relief of social economic burdens.

Epsilon variant mutations contribute to COVID immune evasion

Eurekalert - Jul 06 2021 - 00:07
Three mutations in the Epsilon coronavirus spike protein dampen the neutralizing potency of antibodies induced by current vaccines or past COVID infections. The mutations give this coronavirus variant of concern a means to totally evade specific monoclonal antibodies used in clinics and reduce the effectiveness of antibodies from plasma of vaccinated people. The latest molecular exploration of the mutation-remodeled configuration of the coronavirus infection machinery shows that the Epsilon variant relies on an indirect and unusual neutralization-escape strategy.

Castration delays DNA aging

Eurekalert - Jul 06 2021 - 00:07
It's no secret that women live longer than men. But fellas, if we told you there was one thing that may increase your lifespan, would you do it? New Zealand researchers, in collaboration with Allen Distinguished Investigator Steve Horvath from UCLA, have demonstrated that castration of male sheep delays aging of DNA compared to intact males, and that it also drives feminine characteristics of DNA and the chemical tags it holds, known as DNA methylation.

Long-term urban emissions data show a decrease in high-income countries

Eurekalert - Jul 06 2021 - 00:07
A new study shows how urbanisation has influenced anthropogenic CO2 and air pollutant emissions across all world regions, by making use of the latest developments in the Emissions Database for Global Atmospheric Research (EDGAR, https://edgar.jrc.ec.europa.eu/) developed by the Joint Research Centre of the European Commission. The results show that by 2015 urban centres were the source of a third of global anthropogenic greenhouse gases, and the majority of air pollutant emissions.
