The dna sequence of these microbes could be used to prolong life almost indefinitely.
Bacteria 75 meters below the sea floor began to divide after a light snack.

With only 1% difference, the human and chimpanzee protein-coding genomes are remarkably similar. Understanding the biological features that make us human is part of a fascinating and intensely debated line of research. Researchers at the SIB Swiss Institute of Bioinformatics and the University of Lausanne have developed a new approach to pinpoint, for the first time, adaptive human-specific changes in the way genes are regulated in the brain.
The Turkish metropolis of Istanbul is also known as the “City of Cats,” due to the many thousands of felines living on its streets. However, since the onset of the coronavirus pandemic, life has been tough for these strays.
Circa 2015
Conventional particle accelerators are typically big machines that occupy a lot of space. Even at more modest energies, such as that used for cancer therapy and medical imaging, accelerators need large rooms to accommodate the required hardware, power supplies and radiation shielding.
A new discovery by physicists at the University of Maryland could hold the key to the construction of inexpensive, broadly useful, and portable particle accelerators in the very near future. The team has accelerated electron beams to nearly the speed of light using record-low laser energies, thus relieving a major engineering bottleneck in the development of compact particle accelerators. The work appears in the November 6, 2015 issue of the journal Physical Review Letters.

Chemists at Martin Luther University Halle-Wittenberg (MLU) have developed a way to integrate liquids directly into materials during the 3D printing process. This allows, for example, active medical agents to be incorporated into pharmaceutical products or luminous liquids to be integrated into materials, which allow monitoring of damage. The study was published in Advanced Materials Technologies.
3D printing is now widely used for a range of applications. Generally, however, the method is limited to materials which are liquefied through heat and become solid after printing. If the finished product is to contain liquid components, these are usually added afterwards. This is time-consuming and costly. “The future lies in more complex methods that combine several production steps,” says Professor Wolfgang Binder from the Institute of Chemistry at MLU. “That is why we were looking for a way to integrate liquids directly into the material during the printing process.”
To this endeavor, Binder and his colleague Harald Rupp combined common 3D printing processes with traditional printing methods such as those used in inkjet or laser printers. Liquids are added drop by drop at the desired location during the extrusion of the basic material. This allows them to be integrated directly and into the material in a targeted manner.
““Green tea has five tested chemical compounds that bind to different sites in the pocket on Mpro, essentially overwhelming it to inhibit its function,” Xie said. “Muscadine grapes contain these inhibitory chemicals in their skins and seeds. Plants use these compounds to protect themselves, so it is not surprising that plant leaves and skins contain these beneficial compounds.””
Glad I picked up a refill on my resveratrol this week!
Green tea, muscadine grape and dark chocolate chemical compounds inhibit an important SARS-CoV-2 enzyme.

An epidemiologist who helped to tie the 2012 outbreak of Middle East respiratory syndrome (MERS) to camels; a food-safety officer who studies how pathogens spread in markets; and a veterinarian who found evidence linking the 2014 West Africa Ebola outbreak to bats roosting in a hollow tree. These researchers are among the team that the World Health Organization (WHO) has assembled to investigate the origins of the coronavirus pandemic.
Ten researchers with expertise in virology, public health and animals will seek to answer this key question.
As awe-inspiring as they may be, no one would ever call a supercar practical. But there are certain driving tasks for which only an ultra-high-performance vehicle will do. And, apparently, one of them is transporting a donor organ a long distance in a very short period of time.
That’s the conundrum Italian Police faced earlier this month, reports The Drive. Luckily for all involved, the department happened to have a Lamborghini Huracán on hand to drive the donor kidney 300 miles in just over two hours.
The supercar drove the organ from Rome to Padua in less than half the time it would normally take.
Researchers have identified a cancer-causing mutation in the PDGFRA gene that drives cell mutation and growth when activated. The findings have implications for the treatment of a subset of glioblastoma brain cancer.
Dead Cells
It’s an intriguingly microscopic example of pro-social behavior — an adaptation that doesn’t help an individual survive, but does let it use its death to help others, therefore making the entire swarm more likely to survive and reproduce.
“Dead cells are helping the community survive,” University of Texas at Austin professor of molecular biosciences told Live Science.
