Researchers at Washington University School of Medicine in St. Louis have found that multidrug-resistant bacteria and bacterial spores can be killed by ultrashort-pulse lasers. The findings could lead to new ways to sterilize wounds and blood products …

Melanoma researchers published a study that gives a new explanation of what causes moles to change into melanoma. These findings pave the way for more research into how to reduce the risk of melanoma, delay development, and detect melanoma early.

The petrochemical industry turns oil and gas into precursors used to synthesize lubricants and other critical products. Chemists show that bacteria can be metabolically engineered to generate similar precursors, providing a sustainable replacement for …

One in five individuals avoided healthcare during lockdown in the COVID-19 pandemic, often for potentially urgent symptoms, according to a new study.

Astronomers have discovered an ultrahot Jupiter with shortest orbit of any known gas giant planet.

Researchers have developed a method for incorporating security in the physical nature of the wireless transmission signal for 5G and future networks.

Aspirin use is associated with a 26% raised risk of heart failure in people with at least one predisposing factor for the condition.

Good news for those of us who can’t face the day without their morning flat white: a long-term study has revealed drinking higher amounts of coffee may make you less likely to develop Alzheimer’s disease.

A new study has revealed the death rate of babies in ancient societies is not a reflection of poor healthcare, disease and other factors, but instead is an indication of the number of babies born in that era.

Researchers have developed a technique for assembling optoelectrodes that looks to offer the best of silicon-based electrodes and polymer-based electrodes. The scientists demonstrated it is possible to efficiently create a semiflexible light-emitting e…

Researchers categorize origami- and kirigami-based mechanical metamaterials, artificially engineered materials with unusual mechanical properties, and subdivided them into rigid or deformable categories based on the elastic energy landscape. The resear…

Researchers report developing a database of speech samples from children ages 5 to 18 to explore two questions: What types of changes occur in children’s voices as they become adults, and how do listeners adjust to the enormous variability in acoustic …

A little-known species of tropical bee has evolved an extra tooth for biting flesh and a gut that more closely resembles that of vultures rather than other bees.

The recovery of new lumbar vertebrae from the lower back of a single individual of the human relative, Australopithecus sediba, and portions of other vertebrae of the same female from Malapa, South Africa, together with previously discovered vertebrae,…

NASA’s Mars mission InSight probes the geology of the Elysium Planitia, finding alternate layers of basalt and sediments. An international team of scientists compares on-the-ground data with data from models, which helps to understand, e.g., the surfac…
