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......»»
These New Biomaterials Can Help Decarbonize Fashion and Construction
Designers are imagining a future where bacteria powers both clothing and cement—and their ideas are coming to a shop near you......»»
Sidney Wolk, roadside assistance company founder who dreamed big, dies at 89
Sidney Wolk, who founded Cross Country Motor Club in 1972 and turned it into one of the country's largest networks of independent service providers, died at age 89......»»
Bacteria-derived enzyme shows potential for polyethylene biodegradation
Every year, 400 million tons of plastic products are produced worldwide, half of which are single-use items discarded within a year. In particular, non-biodegradable plastic waste, which takes over 500 years to decompose naturally, is mostly treated.....»»
Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Protein involved in the early stages of age-related macular degeneration offers hope for prevention
Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss in the United States. Despite existing treatments, the underlying causes of this disease and effective therapies remain elusive. Research published in the journal D.....»»
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......»»
How the Apple Watch saved my life
Have you ever almost died? I did, due to a heart attack at the age of 33. In the years since, here's how the Apple Watch has repeatedly saved my life......»»
To build a giant sheep, man spends 10 years smuggling, cloning, and inseminating
He takes his hobbies seriously. Readers of a certain age might remember Dolly, a Finn-Dorset sheep born in 1996 to three mothers and some proud Scottish scientists. Dolly generate.....»»

What’s new in October 2024: 8 new games to look forward to
From remakes like Silent Hill 2 to brand new titles like Dragon Age: The Veilguard, these are some of the games you should be looking forward to in October......»»
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.....»»
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.....»»
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.....»»
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.....»»
