Innovation in Metalworking: Welding Metal Foam Without Melting Its Bubbles

Posted by in category: innovation

North Carolina State University researchers have discovered a new welding method for composite metal foam (CMF), preserving its light, strong, and thermally insulating properties, vital for numerous applications.

Researchers at North Carolina State University have now identified a welding technique that can be used to join composite metal foam (CMF) components together without impairing the properties that make CMF desirable. CMFs hold promise for a wide array of applications because the pockets of air they contain make them light, strong and effective at insulating against high temperatures.

Characteristics and Challenges of CMF.

Supernova Scavenger Hunt: Cracking the Case of Cosmic Ghost Stars

Posted by in categories: cosmology, physics

Supernovae–stellar explosions as bright as an entire galaxy–have fascinated us since time immemorial. Yet, there are more hydrogen-poor supernovae than astrophysicists can explain. Now, a new Assistant Professor at the Institute of Science and Technology Austria (ISTA) has played a pivotal role in identifying the missing precursor star population. The results, now published in Science, go back to a conversation the involved professors had many years ago as junior scientists.

The Enigma of Hydrogen-Poor Supernovae

Watch Tesla Full Self-Driving Beta v12 autonomously look for a parking spot

Posted by in categories: Elon Musk, robotics/AI

A Tesla driver using the new Full Self-Driving (FSD) Beta v12 software managed to showcase a new behavior: FSD Beta autonomously looking for a parking spot.

The Tesla v12 software update is expected to introduce what CEO Elon Musk has been calling “end-to-end neural nets”. The biggest difference with previous FSD updates is that the vehicle’s controls would now be handled by neural nets rather than being coded by programmers.

It is being touted as the difference maker.

Researchers create more realistic synthetic human mini hearts

Posted by in categories: biotech/medical, engineering, health

Thanks to advancements in the development of patented synthetic human-like hearts first created at Michigan State, researchers can study human heart development and congenital heart disease on highly accurate models. This is facilitating the development of new therapies and pharmaceutical drugs to treat a variety of heart-related diseases just in time for the observance of American Heart Month in February.

Similar in size and development to fetal human hearts, these mini heart organoids are becoming increasingly complex and realistic. The MSU research team that created the mini hearts first published their findings in 2020. They have quickly become a world leader in this field and their latest advancements have been published in Nature Communications and Stem Cell Reports.

Aitor Aguirre, associate professor of biomedical engineering and chief of the division of developmental and in MSU’s Institute for Quantitative Health Science and Engineering, explained that the introduction of realistic models is essential to the discovery of effective and clinically translatable solutions to . An estimated 21 million annual deaths are related to this condition, including disorders of the heart and blood vessels. And that number is growing.

Vision impairment in older adults tied to symptoms of depression, anxiety and social isolation: JAMA

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

USA: A cross-sectional study comprising 2,822 US adults revealed that worse examination-based and self-reported vision impairment is associated with anxiety and depressive symptoms, and worse examination-based vision impairment is linked with severe social isolation.

These findings, published in JAMA Ophthalmology, provide evidence to support prioritizing research aimed at enhancing the health and inclusion of people with vision impairment.

Vision impairment and psychosocial function, including symptoms of anxiety, depression and social isolation, are a major cause of morbidity in the US. However, there is a lack of nationally representative studies evaluating associations between subjective and objective vision impairment with psychosocial function following the COVID-19 pandemic.
