Boring to study slow earthquakes

Eurekalert - Jun 28 2021 - 00:06
Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes. For the first time, researchers use deep-sea boreholes to gauge pressures far below the seafloor.

Virtual reality boosts brain rhythms crucial for neuroplasticity, learning and memory

Eurekalert - Jun 28 2021 - 00:06
A new discovery in rats shows that the brain responds differently in immersive virtual reality environments versus the real world. The finding could pave the way for "virtual reality therapy" for learning and memory-related disorders ranging including ADHD, autism, Alzheimer's disease, epilepsy and depression.

Paleonursery offers rare, detailed glimpse at life 518 million years ago

Eurekalert - Jun 28 2021 - 00:06
All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international team of researchers.

New face mask prototype can detect COVID-19 infection

Eurekalert - Jun 28 2021 - 00:06
Engineers at MIT and Harvard have designed a prototype face mask that can diagnose the person wearing the mask with Covid-19 within about 90 minutes. The technology can also be used to design wearable sensors for a variety of other pathogens or toxic chemicals.

A new type of supernova illuminates an old mystery

Eurekalert - Jun 28 2021 - 00:06
A worldwide team led by scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. The discovery also sheds new light on the thousand-year mystery of the supernova from A.D. 1054 that was seen all over the world in the daytime, before eventually becoming the Crab Nebula.

The discovery of a new type of supernova illuminates a medieval mystery

Eurekalert - Jun 28 2021 - 00:06
A worldwide team led by UC Santa Barbara scientists at Las Cumbres Observatory has discovered the first convincing evidence for a new type of stellar explosion -- an electron-capture supernova. While they have been theorized for 40 years, real-world examples have been elusive. They are thought to arise from the explosions of massive super-asymptotic giant branch (SAGB) stars, for which there has also been scant evidence.

First-ever transient pacemaker harmlessly dissolves in body

Eurekalert - Jun 28 2021 - 00:06
The thin, flexible, lightweight device could be used in patients who need temporary pacing after cardiac surgery or while waiting for a permanent pacemaker. All components of the pacemaker are biocompatible and naturally absorb into the body's biofluids over the course of five to seven weeks, without needing surgical extraction.

Face masks that can diagnose COVID-19

Eurekalert - Jun 28 2021 - 00:06
What if your face mask could tell you if you have COVID-19? Now it can, thanks to researchers from the Wyss Institute and MIT. They embedded freeze-dried cell-free biological reactions that can detect SARS-CoV-2 in a patient's breath into a face mask, creating a wearable diagnostic that can quickly and accurately diagnose COVID-19.

Gene variant linked to unnecessary bone marrow biopsies in African Americans

Eurekalert - Jun 28 2021 - 00:06
A gene variant that lowers white blood cell levels and is common in individuals with African ancestry contributes to unnecessary bone marrow biopsies, according to a study published June 28 in JAMA Internal Medicine. The findings from three institutions, led by investigators at Vanderbilt University Medical Center, provide an example of how using genetic data could reduce a health disparity.

Model that explains how charged biopolymers enhance protein clustering in amyloid diseases

Eurekalert - Jun 28 2021 - 00:06
Amyloid diseases, including Alzheimer's, Parkinson's, type-2 diabetes and other life-threatening diseases, involve pathologic deposits of normally soluble proteins or peptides as insoluble amyloid fibrils. When this happens in vital organs, such as the brain, kidney, liver and heart, it causes organ damage and, if left untreated, death. Unfortunately, the available treatment options are very limited.
