Femtosecond laser direct writing “guiding” Leidenfrost droplet motion

A team of scientists has developed a method to control the motion of Leidenfrost droplets on a heated surface using femtosecond laser processing. The droplets exhibit a hybrid boiling state, combining the advantages of film and transition-boiling states, allowing for efficient heat transfer and directional propulsion.

A secret weapon against superbugs

Researchers have developed a new approach to combat superbugs by partnering existing antibiotics with molecular compounds called adjuvants. Using this method, they successfully restored the activity of vancomycin against drug-resistant E. faecium, a potentially life-threatening infection.

GLP-1 diabetes drugs linked to increased risk of hair loss

Researchers have found a potential side effect of GLP-1 receptor agonists used to treat type 2 diabetes: an increased risk of non-scarring alopecia. The absolute risk is low, but awareness may inform treatment decisions. Rapid weight loss and hormonal changes are thought to be contributing factors.

Gut microbiomes follow distinct trajectories during urbanization across South Asia

Researchers found that geography and community affiliation explain more variation in gut microbiome composition than urban lifestyle. Urbanization consistently influences the gut microbiome, but the magnitude and nature of changes differ among communities, reflecting differences in local diets, environments, and cultural practices.

Crowd reactions influence whether people receive controversial political messages positively or negatively

A new study by Aston University researchers suggests that positive crowd reactions like applause and laughter can make controversial political messages more acceptable to viewers. The research found that mixed laughter and booing were particularly damaging to the message, reducing ratings compared to other conditions.

Local policies drive global emissions: The unintended carbon cost of "livestock-free zones"

Local policies in China's 'Livestock-Free Zones' successfully reduced local carbon emissions, but this achievement was overshadowed by a significantly larger 'policy leakage' effect. A study found that for every unit of carbon reduced locally, approximately 3.14 units of carbon emissions were displaced to neighboring regions.

Greener route to acne-care ingredients shows why more antioxidants do not always make a better product

A new extraction method concentrates antioxidant compounds from medicinal plants, but the resulting ingredient's safety and effectiveness depend on various factors. The researchers found that a crude herbal extract was more biologically safe than a highly enriched fraction, despite having lower antioxidant potency.
