Graphene binds drugs that kill bacteria on medical implants
Bacterial infections relating to medical implants place a huge burden on healthcare and cause great suffering to patients worldwide. Now, researchers at Chalmers University of Technology, Sweden, have developed a new method to prevent such infections.....»»
An Ultrathin Graphene Brain Implant Was Just Tested in a Person
A Spanish biotech company sees the carbon material as a way to power the brain-computer interfaces of the future......»»
Scientists inject bacteria into fungi to study endosymbiosis
Endosymbiosis is a fascinating biological phenomenon in which an organism lives inside another. Such an unusual relationship is often beneficial for both parties. Even in our bodies, we find remnants of such cohabitation: mitochondria evolved from an.....»»
LEGO-inspired RNA sensors enable customizable gene control
A research team has developed an RNA-based sensor platform that can regulate gene expression in bacteria. Their findings were recently featured in the journal Advanced Science......»»
Seeing double: Designing drugs that target "twin" cancer proteins
Some proteins in the human body are easy to block with a drug; they have an obvious spot in their structure where a drug can fit, like a key in a lock. But other proteins are more difficult to target, with no clear drug-binding sites......»»
Scientists fear underfunded Argentina research on verge of collapse
Argentine biochemist Alejandro Nadra worries that President Javier Milei's budget cuts will undo his scientific quest to unravel the cause of genetic diseases that disable and kill millions......»»
Pitting good versus bad fungi on sweet corn: A delicate dance
The same defenses that help some varieties of sweet corn resist fungal diseases can also stymie the potency of a beneficial fungus used to kill hungry caterpillar pests, studies by Agricultural Research Service (ARS) scientists suggest. The researche.....»»
Hunting down giant viruses that attack tiny algae
They were said to come from outer space, and there were even claims that they were actually bacteria and that they undermined the very definition of viruses. Giant viruses, nicknamed "giruses," contain enormous quantities of genetic material—up to.....»»
Bioengineers and chemists design fluorescent 3D-printed structures with potential medical applications
In a process as simple as stirring eggs and flour into pancakes, University of Oregon researchers have mixed fluorescent ring-shaped molecules into a novel 3D printing process. The result: intricate glowing structures that support the development of.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
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.....»»
Research reveals best conditions for storing graphene oxide
A research team from Skoltech and other scientific organizations conducted a study to determine which conditions are the most suitable for storing graphene oxide—a promising material that can be used for manufacturing composite materials, gas senso.....»»
Spinning artificial spider silk into next-generation medical materials
It's almost time to dust off the Halloween decorations and adorn the house with all manner of spooky things, including the classic polyester spider webs. Scientists reporting in ACS Nano have made their own version of fake spider silk, but this one c.....»»
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.....»»
Graphene at 20: Still no sign of the promised space elevator, but the material is quietly changing the world
Twenty years ago this October, two physicists at the University of Manchester, Andre Geim and Konstantin Novoselov, published a groundbreaking paper on the "electric field effect in atomically thin carbon films." Their work described the extraordinar.....»»
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......»»
