DARPA teams begin work on tiny brain implant to treat PTSD

Posted by in categories: biotech/medical, computing, neuroscience

Circa 2014 o,.o.


The Defense Advanced Research Projects Agency, or DARPA, has announced the start of a five-year, $26 million effort to develop brain implants that can treat mental disease with deep-brain stimulation.

The hope is to implant electrodes in different regions of the brain along with a tiny chip placed between the brain and the skull. The chip would monitor electrical signals in the brain and send data wirelessly back to scientists in order to gain a better understanding of psychological diseases like Post-Traumatic Stress Disorder (PTSD). The implant would also be used to trigger electrical impulses in order to relieve symptoms.

EPA approves two Lysol products as the first to effectively kill novel coronavirus on surfaces

Posted by in category: biotech/medical

Lysol Disinfectant Spray and Lysol Disinfectant Max Cover Mist meet the EPA’s criteria for use against the SARS-CoV-2, the virus responsible for the ongoing pandemic, based on laboratory testing that found both products kill the virus two minutes after contact, the agency announced in a statement Monday.

While there are more than 420 products on the list of disinfectants that the EPA says are strong enough to ward off “harder-to-kill” viruses than the novel coronavirus, the two Lysol products are the first to have been tested directly against the virus and proved effective.

Quarantine cuisine: Easy meals to support a healthy immune system

Posted by in category: biotech/medical

COVID-19 has led to limited food budgets, and shelter-in-place adds a layer of complexity to buying and planning meals. At the same time, we’re bombarded with ads shouting “Take this supplement to boost your immunity!” So, what’s a person to do?


Filling your cart with the basics might make you feel secure in the short term. But as Dr. Chu found, it’s a different ballgame when you get these items home. Can you make healthy meals with shelf-stable foods? Will the family eat your creation? And does food really boost our immunity? Yes, yes, and yes – over time.

I field questions like these often as director of UT Southwestern’s Culinary Medicine Program. We help people transform food preparation and eating into a healthier part of their daily lives. The program focuses on creating budget-friendly meals with shelf-stable ingredients, as well as mindful eating practices.

Researchers identify nanobody that may prevent COVID-19 infection

Posted by in category: biotech/medical

Researchers at Karolinska Institutet in Sweden have identified a small neutralizing antibody, a so-called nanobody, that has the capacity to block SARS-CoV-2 from entering human cells. The researchers believe this nanobody has the potential to be developed as an antiviral treatment against COVID-19. The results are published in the journal Nature Communications.

“We hope our findings can contribute to the amelioration of the COVID-19 pandemic by encouraging further examination of this nanobody as a therapeutic candidate against this viral infection,” says Gerald McInerney, corresponding author and associate professor of virology at the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet.

The search for effective nanobodies—which are fragments of antibodies that occur naturally in camelids and can be adapted for humans—began in February when an alpaca was injected with the new ’ spike protein, which is used to enter our cells. After 60 days, from the alpaca showed a strong immune response against the spike protein.

Inheritance in plants can now be controlled specifically

Posted by in categories: biotech/medical, evolution, genetics

A new application of the CRISPR/Cas molecular scissors promises major progress in crop cultivation. At Karlsruhe Institute of Technology (KIT), researchers from the team of molecular biologist Holger Puchta have succeeded in modifying the sequence of genes on a chromosome using CRISPR/Cas. For the first time worldwide, they took a known chromosome modification in the thale cress model plant and demonstrated how inversions of the gene sequence can be undone and inheritance can thus be controlled specifically. The results are published in Nature Communications.

About 5,000 years ago, genetic information of thale cress was modified. To date, it has spread widely and is of major interest to science. On the chromosome 4 of the plant, a so-called occurred: The chromosome broke at two points and was reassembled again. The broken out section was reinserted, but rotated by 180°. As a result, the sequence of genes on this chromosome section was inverted. This chromosome mutation known as “Knob hk4S” in research is an example of the fact that evolution cannot only modify the genetic material of organisms, but determine it for a long term. “In inverted sections, genes cannot be exchanged between homologous during inheritance,” molecular biologist Holger Puchta, KIT, explains.

This is a part of a longer interview which you can watch in parts or listen in one go though it is posted on youtube as audio only for the latter.


Let’s say we find a way to reverse aging. How far could we wind things back and when should we do it?

Low-temperature plasma device may lead to more efficient engines

Posted by in categories: biotech/medical, food, nanotechnology

Low-temperature plasmas offer promise for applications in medicine, water purification, agriculture, pollutant removal, nanomaterial synthesis and more. Yet making these plasmas by conventional methods takes several thousand volts of electricity, says David Go, an aerospace and mechanical engineer at the University of Notre Dame. That limits their use outside high-voltage power settings.

In work supported by the U.S. National Science Foundation, Go and a team of researchers conducted research that explores making plasma devices that can be operated without electrical power—they need only human or .

Their paper in Applied Physics Letters introduces a strategy the scientists call “energy-conversion plasma” as an alternative to producing “transient spark” discharges without the need for a very high-voltage power supply.

This Gene May Be Why Women with Alzheimer’s Disease Live Longer

Posted by in categories: biotech/medical, neuroscience, sex

Women with Alzheimer’s disease tend to live longer than men with the disease — and a new study suggests that a gene on the X chromosome may help explain why.

Each person typically has one pair of sex chromosomes in each cell of their body. People assigned female at birth typically have two X chromosomes, while people assigned male at birth typically have one X chromosome and one Y chromosome.

Researchers say a gene called KDM6A may explain why women with Alzheimer’s disease tend to live longer than men with the same condition.
