Lower antibiotic resistance in intestinal bacteria with forgotten antibiotic
A forgotten antibiotic, temocillin, led to lower selection of resistant bacteria than the standard treatment for febrile urinary tract infection. Thus, temocillin may be useful in treating severe urinary tract infections that give rise to fever, and.....»»
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.....»»
This 2004 sci-fi thriller has been largely forgotten. Is it still worth remembering in 2024?
In 2004, Julianne Moore starred in a sci-fi thriller that's been largely forgotten. Is it worth remembering, and watching, in 2024?.....»»
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.....»»
This forgotten Ridley Scott action thriller is better than you remember (and no, it’s not Blade Runner)
From Alien and Blade Runner to 2024's Gladiator II, Ridley Scott has directed some great movies. This 1989 film isn't one of them, but it's still worth a look......»»
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......»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
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.....»»
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......»»
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.....»»
Researchers explore physiological and molecular processes underlying graft healing
Grafting has long been a cornerstone in agriculture and forestry, allowing for the propagation of desirable plant traits and improved resistance to environmental challenges. Despite its widespread application, grafting still encounters obstacles, inc.....»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»
Do bacteria age?
Any organism that lives, grows and reproduces must also age. People often think of aging in the physical sense—gray hair, slowed movements and wrinkles—but aging fundamentally occurs on a molecular level, inside of cells......»»
