Cell muscle movements visualised for first time

Posted by in categories: materials, nanotechnology

The movements of cell muscles in the form of tiny filaments of proteins have been visualised at unprecedented detail by University of Warwick scientists.

In a study published in the Biophysical Journal, scientists from the University’s Department of Physics and Warwick Medical School have used a new microscopy technique to analyse the molecular motors inside that allow them to move and reshape themselves, potentially providing new insights that could inform the development of new smart materials.

Myosin is a protein that forms the motor filaments that give a cell stability and are involved in remodelling the actin cortex inside the cell. The actin cortex is much like the backbone of the cell and gives it its shape, while the myosin filaments are similar to muscles. By ‘flexing’, they enable the cell to exert forces outside of it and to propagate.

Researchers use nanotechnology to develop new treatment for endometriosis

Posted by in category: nanotechnology

Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

Research led by Oleh Taratula of the Oregon State University College of Pharmacy and Ov Slayden of the Oregon National Primate Research Center at Oregon Health & Science University used photo-responsive nanoparticles loaded with dye to find and remove the lesions associated with the disorder.

Findings were published today in the journal Small.

Tesla will slash employee pay and furlough employees

Posted by in categories: biotech/medical, Elon Musk, health, sustainability

Tesla will cut pay for all of its salaried employees and will furlough hourly workers until May 4, when it intends to resume production of electric cars, according to an internal e-mail that multiple employees shared with CNBC. The pay reductions are expected to be in place until the end of the second quarter.

Health orders, implemented to curb the spread of COVID-19, forced Elon Musk’s electric car company to wind down production at its main vehicle assembly plant in Fremont, California.

The new pay cuts follow Tesla’s first-quarter vehicle production and deliveries report, which pleased investors — the company said it delivered approximately 88,400 vehicles and produced 103,000 in Q1. Tesla has yet to withdraw guidance it gave investors for 2020, saying it should “comfortably exceed” 500,000 vehicle deliveries for the year.

Resveratrol and Other Polyphenols Support Genomic Stability

Posted by in categories: biotech/medical, food, genetics, life extension

New research shows that resveratrol, a chemical found in red wine, contributes to genomic stability by reducing the occurrence of DNA double-strand breaks and prolongs lifespan in genetically modified mice that are prone to carcinogenic mutations [1].

DSBs and genomic instability

Genomic instability, one of the hallmarks of aging, is a condition characterized by frequent mutations within the genome, and it has long been associated with cancer [2]. The authors of this study state that one of its major causes is the erroneous repair of DNA double-strand breaks (DSBs). High numbers of DSBs have been found in pre-cancerous cells, and DNA lesions caused by unrepairable DSBs accumulate with time, both in organisms and in cultured cells. One of the possible culprits is the degradation of DNA repair mechanisms in aged cells [3].

Dyson Creates 44 Free Engineering & Science Challenges for Kids Quarantined During COVID-19

Posted by in categories: biotech/medical, education, engineering, science

A heads up: Dyson has “created 44 engineering and science activities for children to try out while at home during the coronavirus pandemic, from making a balloon-powered car to building a bridge from spaghetti,” writes the Dezeen website. They go on to add: “Comprised of 22 science tasks and 22 engineering activities, the Challenge Cards can be completed by children using common household items such as eggs, string and balloons.” You can also find a related playlist of videos on YouTube, one of which appears above.

This engineering/science activities have been added to our refreshed collection, 200 Free Kids Educational Resources: Video Lessons, Apps, Books, Websites & More. If you know of any great K-12 resources, especially ones that are always free, please add them in the comments below, and we will try to add them to the list.
