Metals could be the link to new antibiotics

University of Queensland researchers have discovered 23 metal compounds with antibacterial and antifungal activity, selectively killing bacteria like MRSA but not human cells. The findings offer promise for outwitting bacterial resistance, as the new compounds may use different mechanisms than existing antibiotics.

Hazardous waste or edible food?

A University of Vaasa researcher highlights the need for retailers to adopt creative solutions to reduce bread waste. By managing potential food waste, implementing marketing strategies, and engaging with staff, stores can minimize hazardous waste and meet the UN's Sustainable Development Goals.

How big is the neutron?

Researchers at Ruhr-University Bochum have determined the neutron charge radius from lightest atomic nuclei using a more direct methodology, differing significantly from previous calculations. The new result corrects the previously assumed value for the size of a neutron.

Ohio State first in US to use new atrial fibrillation device

The Ohio State University Wexner Medical Center has successfully used a new atrial fibrillation device, achieving 100% pulmonary vein isolation without nerve injuries or serious side effects. The PFA technology uses pulsed electric fields to interrupt pathways and triggers in the heart, potentially becoming the standard tool for resolv...

UCLA engineers develop miniaturized 'warehouse robots' for biotechnology applications

The researchers created disc-shaped magnets about 2 millimeters in diameter, called ferrobots, which can move and manipulate droplets of fluid with precision. These robots could transform various biotech-related industries, including medical diagnostics, drug development, genomics, and the synthesis of chemicals and materials.

Researchers overcome the space between protons and neutrons to study heart of matter

Researchers used novel method to access space between protons and neutrons, capturing snapshots of correlations to study nuclear matter. They found that leading theories on interactions describe the strong nuclear force at short distances, with a tensor interaction at close range and a scalar interaction at smaller scales.

New bile discovery will rewrite textbooks

Scientists at Michigan State University discovered new bile acids produced by microbes in the gut, which expand our understanding of mammalian bile and its connection to gastrointestinal diseases. These novel acids are particularly abundant in people suffering from conditions like Crohn's disease and cystic fibrosis.

Drinks with added sugars linked to lipid imbalance, which increases CVD risk

A new observational study published in the Journal of the American Heart Association found that drinking 12 ounces of sugary drinks more than once per day is linked to lower levels of HDL-C and higher levels of triglycerides. The study also found that regularly consuming sugar-sweetened beverages increases the risk of cardiovascular di...

Potential new heartburn drug studied at VUMC

A new study suggests that investigational drug IW-3718 can reduce the severity of heartburn symptoms in patients with treatment-resistant gastroesophageal reflux disease (GERD) when combined with a proton pump inhibitor (PPI). The study, conducted by Vanderbilt University Medical Center and Ironwood Pharmaceuticals, found significant r...

Seagulls favor food humans have handled

New research shows that seagulls are more likely to peck at food that has been handled by humans. This suggests they use human actions when deciding what to eat. The study, published in Royal Society Open Science, also found that gulls' preference for food is not just based on the sight of food.

Stimulating resonance with two very different forces

Parametric oscillators can be made to resonate when driven by high and low frequencies, a discovery that could improve our understanding of nonlinear systems in various fields. This is achieved through the tuning of the high-frequency driving force to match the low frequency, causing the system to exhibit resonance.
