New treatment for fear-related anxiety disorders by extinguishing fear memories

Researchers at The University of Queensland have discovered a DNA modification that enhances our ability to extinguish fear. The findings, published in the journal Nature Neuroscience, could help guide the development of new treatments for fear-related anxiety disorders. Professor Timothy Bredy of UQ’s Queensland Brain Institute (QBI) said while fear is an important survival mechanism which uses cues in

Could cooling computers be a simple as running an LED with the electrodes reversed?

In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away. The approach could lead to new solid-state cooling technology for future microprocessors, which will have so many transistors packed

Scientific discoveries made by machine-learning techniques should be checked for accuracy and reproducibility

Rice U. expert: Key is creating ML systems that question their own predictions Rice University statistician Genevera Allen says scientists must keep questioning the accuracy and reproducibility of scientific discoveries made by machine-learning techniques until researchers develop new computational systems that can critique themselves. Allen, associate professor of statistics, computer science and electrical and computer engineering at

A single systemic treatment using CRISPR can safely and stably correct a genetic disease – Duchenne muscular dystrophy – in mice

Genetic edits and protein restoration in mouse models of Duchenne muscular dystrophy remain viable one year after single CRISPR treatment Researchers at Duke University have shown that a single systemic treatment using CRISPR genome editing technology can safely and stably correct a genetic disease — Duchenne muscular dystrophy (DMD) — for more than a year

New CRISPR-Cas9 gene editing technique prevents rejection of stem cell transplants

Technique Prevents Transplant Rejection in the Lab, a Major Advance for Stem Cell Therapies UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally “invisible” to the immune system, a feat of biological engineering that, in laboratory studies, prevented rejection of stem cell transplants. Because

Controlling deadly allergic reactions by controlling an immune cell function

In cases of severe, even deadly, allergic reactions to foods such as peanuts and fish, immune cells go into hyperdrive. This can trigger anaphylactic shock, sending blood pressure plummeting and obstructing breathing. Michigan State University scientists have identified a master control mechanism on mast cells, a type of immune cell, that can prevent the immune

A blood test for pain?

A breakthrough test developed by Indiana University School of Medicine researchers to measure pain in patients could help stem the tide of the opioid crisis in Indiana, and throughout the rest of the nation. A study led by psychiatry professor Alexander Niculescu, MD, PhD and published this week in the high impact Nature journal Molecular Psychiatry tracked hundreds of

Could biosynthetic fibers solve our unseen plastic pollution?

While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem. “These materials, during production, processing and after

Can desalination waste be turned into a useful resource?

Process developed at MIT could turn concentrated brine into useful chemicals, making desalination more efficient The rapidly growing desalination industry produces water for drinking and for agriculture in the world’s arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed of by dumping it

Could the key to treating Crohn’s disease be using patients’ own modified cells?

A new technique using patients’ own modified cells to treat Crohn’s disease has been proven to be effective in experiments using human cells, with a clinical trial of the treatment expected to start in the next six months. Researchers at the NIHR Guy’s and St Thomas’ Biomedical Research Centre (BRC) developed the technique by studying white blood

The promise of stem cell technologies for treating Parkinson’s

Despite challenges, new advances in stem cell biology and genetic engineering show potential for better cell replacement therapies, say experts in a special supplement to JPD Cell replacement may play an increasing role in alleviating the motor symptoms of Parkinson’s disease (PD) in future. Writing in an open access special supplement to the Journal of Parkinson’s Disease, experts describe how
