Climate-friendly microbes chomp dead plants without releasing heat-trapping methane

Scientists have identified a new phylum of microbes found around the world that appear to be playing an important (and surprising) role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane. The phylum is named Brockarchaeota after Thomas Brock, a pioneer in the study of microbes that live in extreme environments who died on April 4.

New blood markers may reveal heart attack in chest pain patients

When a patient with chest pain arrives at hospital, time is of the essence. Doctors must quickly rule heart attack in or out and start treatment as soon as possible. A new study reveals blood biomarkers that could help. By analyzing blood samples from patients with chest pain, researchers found a unique fingerprint of heart attack in the form of blood biomarkers. The results could help doctors to...

Patching up your health

Researchers from Osaka University and JOANNEUM RESEARCH develop ultrathin piezoelectric flexible patches that harvest the body's energy to monitor the patient's pulse and blood pressure. This work may lead to novel biosensors and self-powered wearable electronics.

People with heart rhythm disorders warned over cannabis use

: A study of 2.4 million hospitalised cannabis users has found that those with an arrhythmia were 4.5 times more likely to die while in hospital than those without. The research is presented at EHRA 2021, an online scientific congress of the European Society of Cardiology (ESC). "People should be aware of this devastating outcome and be careful when using cannabis if they have a concomitant heart...

Quantum steering for more precise measurements

Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles.

3D printed models provide clearer understanding of ground motion

It seems like a smooth slab of stainless steel, but look a little closer, and you'll see a simplified cross-section of the Los Angeles sedimentary basin. Caltech researcher Sunyoung Park and her colleagues are printing 3D models like the metal Los Angeles proxy to provide a novel platform for seismic experiments.

A new method for fighting 'cold' tumors

Researchers Michael Knitz and radiation oncologist and University of Colorado Cancer Center member Sana Karam, MD, PhD, address cold tumors in new research published this week in the Journal for ImmunoTherapy of Cancer. Working with mouse models in Karam's specialty area of head and neck cancers, Knitz and Karam studied the role of T cells in tumor treatment.

A new study identifies interleukin 11 as a marker of cancer-associated fibroblasts

A research group led by Prof. Hiroyasu Nakano of Department of Biochemistry, Toho University Faculty of Medicine, found that interleukin 11 (IL-11)-positive cells rapidly appear in the colons of mice with colitis and colitis-associated colorectal cancers. In RNA-seq analysis of the gene expression profiles, they found that high expression of enriched genes in IL-11-positive fibroblasts correlated...

ALMA discovers rotating infant galaxy with help of natural cosmic telescope

Using ALMA, astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark "normal galaxies" in the early Universe, which greatly advances our understanding of the initial phase of...

Among COVID-19 survivors, an increased risk of death, serious illness

Researchers at Washington University School of Medicine in St. Louis showed that COVID-19 survivors -- including those not sick enough to be hospitalized -- have an increased risk of death in the six months following diagnosis with the virus. They also have catalogued the numerous diseases associated with COVID-19, providing a big-picture overview of the long-term complications of COVID-19 and...

Anti-aging compound improves muscle glucose metabolism in people

In the first clinical trial of nicotinamide mononucleotide (NMN), researchers at Washington University School of Medicine in St. Louis have found that the compound previously demonstrated to counteract aspects of aging and improve metabolic health in mice also has clinically relevant effects in people.

Army-funded research paves way for improved lasers, communications

New photonics research paves the way for improved lasers, high-speed computing and optical communications for the Army. Using light's speed and the way information can be layered in its various physical properties can increase the speed of communication while reducing wasted energy; however, light sources such as lasers need to be smaller, stronger and more stable to achieve that, researchers...

Artificial intelligence model predicts which key of the immune system opens the locks of coronavirus

With an artificial intelligence (AI) method developed by researchers at Aalto University and University of Helsinki, researchers can now link immune cells to their targets and for example uncouple which white blood cells recognize SARS-CoV-2. The developed tool has broad applications in understanding the function of immune system in infections, autoimmune disorders, and cancer.
