High resolution ultrasound could enable faster prostate cancer diagnosis
2025-03-23
Biopsies guided by high resolution ultrasound are as effective as those using MRI in diagnosing prostate cancer, an international clinical trial has shown.
The technology, called micro-ultrasound, is cheaper and easier to use than MRI. It could significantly speed up diagnosis, reduce the need for multiple hospital visits and free up MRI for other uses, researchers say.
The results of the OPTIMUM trial are presented today [Sunday 23 March 2025] at the European Association of Urology Congress in Madrid and published in JAMA.
OPTIMUM is the first randomised trial to compare micro-ultrasound (microUS) guided biopsy with ...
Guardians of the vineyard: Canines and chemistry work to combat powdery mildew
2025-03-23
SAN DIEGO, March 23, 2025 — Dogs have many jobs but one you may not expect is identifying grapevines coated in a destructive and highly contagious fungus. Although dogs can detect serious vine infections by smell, scientists don’t know exactly what odor molecules are triggering the response. Researchers are now analyzing volatile chemicals emanating from grape leaves infected by a fungus called powdery mildew with the goal of improving training for vineyard canines.
Nayelly Rangel, a graduate student at Texas Tech University, will present the team’s results at the spring meeting of the American Chemical Society (ACS). ACS Spring 2025 is being held ...
Improving GLP-1 drug delivery by ‘painting’ it on antibodies
2025-03-23
SAN DIEGO, March 23, 2025 — Glucagon-like peptide-1 (GLP-1) receptor agonists are peptide-based therapeutics for treating diabetes and for weight loss. Unfortunately, shortages and high costs have made it difficult for people to start and maintain treatment. Now, researchers report a drug delivery system that “paints” these peptides directly on the antibodies they target. In studies with mice, the system led to sustained weight loss and prolonged blood sugar management with a GLP-1 injection one fourth that of the standard dose.
Bradley Pentelute, professor of chemistry at the Massachusetts Institute of Technology (MIT), will present his team’s results at the spring ...

Origin of life: How microbes laid the foundation for complex cells
2025-03-21
Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form of microbes.
With computer assistance, the researchers assembled these fragments like puzzle pieces to compile the entire genome. It was only then that they realised they were dealing with a previously unknown group of archaea.
Like bacteria, archaea are single-celled organisms. Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and metabolic processes.
After ...
How the brain links related memories formed close in time
2025-03-21
COLUMBUS, Ohio – If you’ve ever noticed how memories from the same day seem connected while events from weeks apart feel separate, a new study reveals the reason: Our brains physically link memories that occur close in time not in the cell bodies of neurons, but rather in their spiny extensions called dendrites.
This discovery stems from studies in mice, in which researchers observed memory formation using advanced imaging techniques, including miniature microscopes that captured single-cell resolution in live animals.
The study shows that memories are stored in dendritic compartments: When one memory forms, the affected ...
Case study: Bartonella, babesia, found in brain tissue of child with seizures
2025-03-21
In a new case study, researchers from North Carolina State University found Bartonella henselae, Babesia odocoilei and Babesia divergens-like MO-1 DNA in brain tissue samples from a young child with seizures and suspected Rasmussen’s encephalitis. The findings further support the idea that these pathogens can be a cofactor in complex neurological illnesses.
Bartonella are a group of vector-borne bacteria transmitted primarily via arthropods like fleas, lice and potentially ticks, but also by the animals that harbor them. Of the (at least) 45 currently known Bartonella species, ...
“Concierge” screening for kidney transplant candidates leads to better outcomes, UNM researcher finds
2025-03-21
Patients hoping for a kidney transplant must first undergo a battery of medical tests to determine whether they are suitable candidates for the procedure and healthy enough to take post-transplant immunosuppressant drugs to prevent organ rejection.
In most transplant centers, the burden falls on the patient to arrange tests like cardiac catheterization, CT scans, mammograms or colonoscopies, which can year or more to complete, meaning some people never complete the process, while others get sicker or die.
But a new study published in JAMA Internal Medicine led by a University of New Mexico Health Sciences researcher demonstrates that a “concierge” ...
New study sheds light on how bacteria ‘vaccinate’ themselves with genetic material from dormant viruses
2025-03-21
FOR IMMEDIATE RELEASE
Key Takeaways:
Bacteria get invaded by viruses called phages.
Scientists are studying how bacteria use CRISPR to defend themselves from phages, which will inform new phage-based treatments for bacterial infections that are resistant to antibiotics.
Bacteria seize genetic material from weakened, dormant phages and use it to form a biological “memory” of the invader that their offspring inherit and use for anti-phage defense.
Like people, bacteria get invaded by viruses. In bacteria, the viral invaders are called bacteriophages, ...
Four advances that could change tuberculosis treatment
2025-03-21
As of early 2025, tuberculosis cases are increasing in the U.S. This disease, often shortened to TB, causes significant lung damage and, if not treated, is almost always lethal. World TB Day on March 24 raises awareness about the disease and commemorates Robert Koch’s discovery of the source bacterium Mycobacterium tuberculosis. More than a century later, scientists continue refining TB diagnosis methods and treatment strategies, some of which are in these four ACS journal articles.

New Microbiology Society policy briefing on Antimicrobial Resistance (AMR) in wastewater
2025-03-21
AMR occurs when disease-causing bacteria, viruses, fungi and parasites (pathogens) are no longer affected by the medicines that have been developed to target them. Drug-resistant pathogens can cause infections that are difficult or impossible to treat; they increase the risk of disease spread and can lead to severe illness, disability and death.
Wastewater is commonly contaminated with antimicrobial resistant micro-organisms and antimicrobial compounds. Upon entering our environment, such as rivers and seas, contaminated wastewater therefore serves as a pathway for, and major contributor to, the spread of AMR in the UK and ...
Transition point in romantic relationships signals the beginning of their end
2025-03-21
The end of a romantic relationship usually does not come out of the blue but is indicated one or two years before the breakup. As the results of a psychological study have demonstrated, the terminal stage of a relationship consists of two phases. First, there is a gradual decline in relationship satisfaction, reaching a transition point one to two years before the dissolution of the relationship. "From this transition point onwards, there is a rapid deterioration in relationship satisfaction. Couples in question then move towards separation," said Professor ...
