Single test for over 50 genetic diseases will cut diagnosis from decades to days

Posted: 04 Mar 2022 11:46 AM PST

A single DNA test has been developed that can screen a patient's genome for over 50 genetic neurological and neuromuscular diseases such as Huntington's disease, muscular dystrophies and fragile X syndrome. The new test avoids a 'diagnostic odyssey' for patients that can take decades. The team has shown that the test is accurate. They are now working on validations to make it available in pathology labs. They expect it to be standard in global pathology labs within five years.

Making diversity, equity, inclusion integral part of physics education

Posted: 04 Mar 2022 09:40 AM PST

While many physics instructors are beginning to incorporate lessons on diversity, equity, and inclusion in the classroom, it can often feel like an add-on rather than an integral component of becoming a physicist. Scientists are helping to change this by presenting discussions and activities on DEI as a fundamental and essential part of physics training. The team created two approaches for DEI curriculum, replacing a question on a weekly homework assignment with a reflection essay on a topic important to physicists and including activities and discussions during a two-day unit on representation.

Changing the standard of care for stage III melanoma surgery

Posted: 04 Mar 2022 09:40 AM PST

For years, surgery for patients with stage III melanoma -- melanoma that has spread to the lymph nodes -- involved removing those lymph nodes along with the primary tumor. Known as completion lymph node dissection (CLND), the surgery was meant to ensure that no cancer remained after surgery. More recently, however, cancer surgeons have discovered that CLND has the potential to cause more problems than it solves. In most cases, patients do better on immunotherapy alone than they do when their surgery involves removal of the lymph nodes, due to potential complications from lymph node surgery.

Researchers map magnetic fields in 3D, findings could improve device storage capacity

A new study relates liquid fructose intake to fatty liver disease

Posted: 04 Mar 2022 08:20 AM PST

A high-fat diet is not enough to cause short-term fatty liver disease. However, if this diet is combined with the intake of beverages sweetened with liquid fructose, the accumulation of fats in the liver accelerates and hypertriglyceridemia -- a cardiovascular risk factor -- can appear, according to researchers.

Major automotive manufacturers are ramping up production of electric trucks as a key strategy to reduce the greenhouse gas emissions of their vehicles.

Microneedle approach to address peanut allergy shows promise in mice

Posted: 04 Mar 2022 08:20 AM PST

Mice that received treatments with peanut-coated microneedles had significant increased rates of desensitization to peanut allergy compared with epicutaneous immunotherapy (EPIT), a new study found. The microneedle treatment success was achieved despite applying a dose of peanut protein 10-times lower than the dose delivered by EPIT. Researchers say the findings demonstrate the potential for peanut microneedles to improve food allergen immunotherapy through the skin.

Mindfulness meditation can reduce guilt, leading to unintended negative social consequences, study finds

Posted: 04 Mar 2022 07:10 AM PST

Mindfulness meditation is a stress-management practice with ancient lineage that cultivates nonjudgmental awareness of the present moment, often by directing attention to the physical sensations of breathing. But there may be an unanticipated downside to secular mindfulness meditation practices, according to new research.

'Fingerprint' machine learning technique identifies different bacteria in seconds

Posted: 04 Mar 2022 07:10 AM PST

Bacterial identification can take hours and often longer -- precious time when diagnosing infections and selecting appropriate treatments. There may be a quicker, more accurate process. By teaching a deep learning algorithm to identify the 'fingerprint' spectra of the molecular components of various bacteria, the researchers could classify various bacteria in different media with accuracies up to 98%.

Predicting solar cell performance from terahertz and microwave spectroscopy

Posted: 04 Mar 2022 07:09 AM PST

Many semiconducting materials are possible candidates for solar cells. In recent years, perovskite semiconductors in particular have attracted attention, as they are both inexpensive and easy to process and enable high efficiencies. Now a new study shows how terahertz (TRTS) and microwave spectroscopy (TRMC) can be used to reliably determine the mobility and lifetime of the charge carriers in new semiconducting materials. Using these measurement data it is possible to predict the potential efficiency of the solar cell in advance and to classify the losses in the finished cell.

More alcohol, less brain: Association begins with an average of just one drink a day

Posted: 04 Mar 2022 06:03 AM PST

Even light-to-moderate drinking is associated with harm to the brain, according to a new study. Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day -- the equivalent of about half a beer -- and rises with each additional drink.

Henipavirus glycoprotein architecture suggests therapeutic strategies

Posted: 04 Mar 2022 06:03 AM PST

3D structural findings are reported on a critical component of the Nipah virus' infection mechanism, and how antibodies home in on an important part of the machinery that attaches the virus to host cells. The results point to multipronged strategies for preventing and treating the deadly Nipah and Hendra viruses, which are carried by bats, but which have jumped species to infect other animals and people. The results of this latest research suggest a blueprint for computer-engineered, next-generation vaccine candidates,

This is the first study to assess such a large number of proteins for their connection to COVID-19. The findings provide insight into potential new targets for approaches to treat and prevent severe COVID-19.

Researchers find 'genetic baggage' accumulates in the genomes of aging mutant animals

Posted: 03 Mar 2022 11:12 AM PST

You are probably familiar with the term that some people carry 'a lot of extra baggage.' Usually that term refers to that person's emotional history, but in genetics and our genomes, 'extra baggage' can also describe the transposons lurking in our genomes, a historical record of our genomes surviving traumatic invasions during evolution. Transposons are repetitive DNA sequences that have the capability to move (transpose) from one location to another in the genome (an organism's complete set of genetic instructions) and are considered important invaders of our genomes during evolution.

Cohorting patient care model during pandemic improved patient outcomes, researchers find

Posted: 03 Mar 2022 09:50 AM PST
