The soft "spaghetti" of proteins that"s essential for the resistance of bacteria
Bacteria are increasingly resistant, especially to antibiotics, which is a major global health problem. An example, related to the pandemic? Covid weakens hospitalized people so much that we are now witnessing an upsurge in bacterial infections (resi.....»»
Researcher develops low-sugar ice cream with smooth texture
Wageningen researcher Qi Wang has developed a new variant of low-sugar ice cream that mimics the texture and melting properties of traditional ice cream. By replacing half of the sugar with broken-down proteins or the sweetener xylitol, she succeeded.....»»
Strategies for maximizing recombinant protein production in tobacco plants
Plant molecular farming (PMF) is a modern, sophisticated technology that utilizes plants' biosynthetic machinery to synthesize a plethora of recombinant proteins, including industrial and therapeutic enzymes. It has several advantages over traditiona.....»»
Tailwinds don’t help “everesting” cyclists
"There are no clever tricks to get around the necessary diet and exercise." Enlarge / Physicist Martin Bier in an aerodynamic tuck, a cycling position that reduces wind resistance. (credit: Martin Bier) Many avid bicycli.....»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Broadcom responds to AT&T’s VMware support lawsuit: AT&T has “other options”
Broadcom defends against renewal, citing "End of Availability" provision. Enlarge (credit: Getty) Broadcom is accusing AT&T of trying to "rewind the clock and force" Broadcom "to sell support services for perpetual soft.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
VW CEO Oliver Blume expects significant concessions from unions in crunch talks
VW Group CEO Oliver Blume said the automaker's costs in Germany are too high compared to international competition, setting up a clash with unions who have pledged fierce resistance to job cuts and plant closures......»»
Potential breakthrough in battle against antibiotic resistance from historic brine
A historic brine bath is the site of a potential breakthrough in the prevention of antibiotic resistance in relation to MRSA, and other hospital pathogens......»»
A new catalog charts the evolution of the universe over time
An atlas doesn't seem to be an essential item in cars these days, but think about them and most people will think about distances. An atlas of the stars not only covers distances but must also take into account time too. The Andromeda galaxy, for exa.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
From chaos to order: Proteins can re-structure themselves to create important substances
The protein "MIPS" changes its internal structure when it becomes active. Its disordered active center becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8,.....»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
EmuDeck is slowly taking over my PC gaming setup
EmuDeck is a quick way to set up emulators on your Steam Deck, but it's slowly grown to be an essential app on my main gaming PC......»»
New method developed to relocate misplaced proteins in cells
Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally s.....»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Genome sequence analysis identifies new driver of antimicrobial resistance
Antibiotics are a lifesaving tool. Yet, due to their chronic overuse, microbes are evolving and developing immunity against them. As a result, once-effective medications can no longer stave off infections, complicating treatment and increasing mortal.....»»
