Recently, the PLA has put into service a new low-altitude air defense system (SHORAD), which looks similar to the recently deployed US SHORAD Stryker defence system.
According to a video released by China State Television (CCTV), China’s new SHORAD system, consisting of a 35mm anti-aircraft ԍuɴ along with two surface-to-air missiles, is mounted on an armored vehicle chassis. steel 8×8 wheels.
A cancer treatment that uses messenger RNA to launch an immune attack on cancer cells can completely shrink tumours in mice and is now being tested in people.
Messenger RNAs – or mRNAs – are molecules that instruct cells to make proteins. They have risen to fame with the roll out of mRNA covid-19 vaccines.
Exploring The Gut Microbiota-Brain Axis In Health, Disease, and Aging — Dr. Marina Ezcurra, Ph.D. University of Kent.
Dr. Marina Ezcurra (https://marinaezcurralab.com/) is a Lecturer in the Biology of Aging, and NeuroBiology, at the School of BioSciences, at the University of Kent, UK (https://www.kent.ac.uk/biosciences/people/2081/ezcurra-marina).
Dr. Ezcurra received her PhD from the Karolinska Institute in 2011. Her PhD research was a collaborative project between Karolinska and the Medical Research Council Laboratory of Molecular Biology at Cambridge, where she studied neural circuits and behavior using C. elegans in the lab of Dr. Bill Schafer.
During her PhD, Dr. Ezcurra identified extra-synaptic mechanisms by which nutritional status modulates nociception, involving neuro-peptidergic and dopaminergic signaling. She went on to do a postdoc working on aging with Dr. David Gems at University College London.
During her postdoc, Dr. Ezcurra developed methods to monitor the development of multiple age-related diseases in-vivo in C. elegans, leading to the discovery of a previously unknown process, Intestinal Biomass Conversion. This mechanism enables the C. elegans intestine to be broken down to produce vast amounts of yolk, resulting in poly-morbidity and mortality in aging nematodes. This work illustrates how aging and age-related diseases can be the result of run-on of wild-type gene function, rather than stochastic molecular damage.
Mentions telomeres.
~~~
People with rare disorders that cause shortened telomeres—protective caps that sit at the end of chromosomes—may be more likely to have blood cancers such as leukemia or myelodyplastic syndrome. Now, Johns Hopkins Medicine scientists have discovered several “self-correcting” genetic mutations in bone marrow that may protect such patients from these cancers.
In a study published online August 3 2021, in the Journal of Clinical Investigation, the researchers also suggest these mutations can serve as biomarkers that may indicate if patients with short telomere syndromes are likely to develop blood cancers.
“These are the most common cancers we see in patients with short telomere syndromes,” says Mary Armanios, M.D., director of the Telomere Center and professor of oncology at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins. “We know that at a certain point, the cells of patients with shortened telomeres either become cancerous or stay healthy.”
Circa 2020
The setup of lasers and mirrors effectively “solved” a problem far too complicated for even the largest traditional computer system.
Optical lattice clocks could help scientists detect gravitational waves, hunt for dark matter and much more.
Two physicists just snagged $3 million for helping develop a super-precise clock that could allow scientists to study and explore the universe like never before.
Summary: Researchers have identified 2,000 genes in humans linked to longevity. The genes are associated with biological mechanisms that drive the prolongation of life in mammals, including DNA repair, coagulation, and immune response.

What determines the life expectancy of each species? This is a fundamental and highly complex question that has intrigued the field of research throughout history. From the evolutionary point of view, the major cause of these differences between species lies in their ecological adaptations. For example, life expectancy is longer in species adapted to living in trees, underground, or with large body mass, since all these adaptations reduce mortality by predation.
I recently set sail on Sunwater Marine’s Ramblin’ Rose, a 40-foot sailing yacht powered by solar panels and electric propulsion.
While we at Electrek often tend to focus on electric vehicles taking over roads, it’s important to remember that our inevitable abandonment of fossil fuels stems to all modes of transportation, whether it’s by land, air, or even the sea. I recently had the opportunity to set sail on Sunwater Marine’s Ramblin’ Rose, a 40-foot sailing yacht powered by solar panels and electric propulsion. It’s one of the only vessels of its kind on the West Coast.
It was founded by president James Richmond in 2,020 amid the global pandemic. Richmond had a little more free time to search for a boat for blue water cruising to which he could add solar.
