A link between childhood stress and early molars

Eurekalert - Jun 09 2021 - 00:06
Research from the University of Pennsylvania's Allyson Mackey and graduate student Cassidy McDermott shows that children from lower-income backgrounds and those who go through greater adverse childhood experiences get their first permanent molars sooner. The findings align with a broader pattern of accelerated development often seen under conditions of early-life stress.

Study shows adaptive brain response to stress, and its absence in people with depression

Eurekalert - Jun 09 2021 - 00:06
A new study identifies a novel biomarker indicating resilience to chronic stress. This biomarker is largely absent in people suffering from major depressive disorder, and this absence is further associated with pessimism in daily life, the study finds.

Astronomers discover a 'changing-look' blazar

Eurekalert - Jun 09 2021 - 00:06
A University of Oklahoma doctoral student, graduate and undergraduate research assistants, and an associate professor in the Homer L. Dodge Department of Physics and Astronomy in the University of Oklahoma College of Arts and Sciences are lead authors on a paper describing a 'changing-look' blazar -- a powerful active galactic nucleus powered by supermassive blackhole at the center of a galaxy. The paper is published in The Astrophysical Journal.

Origin of fairy circles: Euphorbia hypothesis disproved

Eurekalert - Jun 09 2021 - 00:06
The fairy circles of the Namib are one of nature's greatest mysteries. Millions of these circular barren patches extend over vast areas along the margins of the desert in Namibia. An early hypothesis by G.K. Theron was that poisonous substances from Euphorbia damarana leaves induced fairy circles. Now new research at Göttingen University and the Gobabeb Namib Research Institute found the original experiment and, 40 years later, the researchers are able to conclusively disprove this hypothesis.

The impact of double-cropping

Eurekalert - Jun 09 2021 - 00:06
A new study published in Nature Food quantifies for the first time the impact that double-cropping had on helping Brazil achieve its national grain boom. Jing Gao, assistant professor of geospatial data science in the University of Delaware's College of Earth, Ocean and Environment (CEOE) and Data Science Institute (DSI), was a co-author on the study that included collaborators from institutions in China and Brazil.

Corals' natural 'sunscreen' may help them weather climate change

Eurekalert - Jun 09 2021 - 00:06
Smithsonian Conservation Biology Institute scientists are one step closer to understanding why some corals can weather climate change better than others, and the secret could be in a specific protein that produces a natural sunscreen.

Study suggests unmedicated, untreated brain illness is likely in mass shooters

Eurekalert - Jun 09 2021 - 00:06
The first analysis of medical evidence on domestic mass shooters in the US finds that a large majority of perpetrators have psychiatric disorders for which they have received no medication or other treatment, reports a study in the Journal of Clinical Psychopharmacology. The journal is published in the Lippincott portfolio by Wolters Kluwer.

Common mechanism found for diverse brain disorders: Study

Eurekalert - Jun 09 2021 - 00:06
Researchers at Vanderbilt University Medical Center (VUMC) have identified a common mechanism underlying a spectrum of epilepsy syndromes and neurodevelopmental disorders, including autism, that are caused by variations in a gene encoding a vital transporter protein in the brain.

A new culprit in antibacterial resistance: cysteine persulfide

Eurekalert - Jun 09 2021 - 00:06
A joint research project based in Kumamoto University, Japan has developed a new, highly sensitive analytical method that can detect degraded β-lactam antibacterial agents used in the treatment of bacterial infections. With this method, researchers found that reactive sulfur species produced by bacteria degrade and inactivate β-lactam antibiotics.

Single-Shot COVID-19 Vaccine Generates Robust Immune Responses Against COVID-19 Variants

Eurekalert - Jun 09 2021 - 00:06
In a new study published in Nature, Dan Barouch, MD, PhD, Director of Beth Israel Deaconess Medical Center's Center for Virology and Vaccine Research, and colleagues report on the antibody and cellular immune responses generated by the Ad26.COV2.S vaccine against the original viral strain and against SARS-CoV-2 variants of concern. The team found that this vaccine induced immune responses against all the viral variants.

Study: Important contribution to spintronics has received little consideration until now

Eurekalert - Jun 09 2021 - 00:06
The movement of electrons can have a significantly greater influence on spintronic effects than previously assumed. This discovery was made by an international team of researchers led by physicists from the Martin Luther University Halle-Wittenberg (MLU). Until now, a calculation of these effects took, above all, the spin of electrons into consideration. The study was published in the journal "Physical Review Research" and offers a new approach in developing spintronic components.

Assessing feasibility concerns in climate mitigation scenarios

Eurekalert - Jun 09 2021 - 00:06
What drives the feasibility of climate scenarios commonly reviewed by organizations like the Intergovernmental Panel on Climate Change (IPCC)? And can they actually be extrapolated to the real world? A new systematic framework can help understand what to improve in the next generation of scenarios and explore how to make ambitious emission reductions possible by strengthening enabling conditions.

Brain connections mean some people lack visual imagery

Eurekalert - Jun 09 2021 - 00:06
New research has revealed that people with the ability to visualize vividly have a stronger connection between their visual network and the regions of the brain linked to decision-making. The study also sheds light on memory and personality differences between those with strong visual imagery and those who cannot hold a picture in their mind's eye.
