Microarray patches safe and effective for vaccinating children, trial suggests

The first study of the use of microarray patches to vaccinate children has shown that the method is safe and induces strong immune responses. The phase 1/2 randomized trial compared results from the measles and rubella vaccine delivered by a microarray patch, a small sticking plaster-like device with an array of microscopic projections that painlessly penetrate the skin and deliver the vaccine, or by conventional injection with a needle and syringe.

A virus could help save billions of gallons of wastewater produced by fracking

An estimated 168 billion gallons of wastewater -- or produced water -- is generated annually by the Permian Basin fracking industry, according to a 2022 report. The major waste stream has proved both difficult and costly to treat because of the chemical complexity of the water.

These giant, prehistoric salmon had tusk-like teeth

Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.

Ancient Maya blessed their ballcourts

Using environmental DNA analysis, an international team of researchers identified a collection of plants used in ceremonial rituals in the ancient Maya city of Yaxnohcah in Mexico. The plants, known for their religious associations and medicinal properties, were discovered beneath a plaza floor where a ballcourt was built.

New circuit boards can be repeatedly recycled

Researchers have developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer -- a cutting-edge class of polymer -- into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these 'vPCBs' (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

Using stem cell-derived heart muscle cells to advance heart regenerative therapy

Regenerative heart therapies involve transplanting cardiac muscle cells into damaged areas of the heart to recover lost function. However, the risk of arrhythmias following this procedure is reportedly high. In a recent study, researchers tested a novel approach that involves injecting 'cardiac spheroids,' cultured from human stem cells, directly into damaged ventricles. The highly positive outcomes observed in primate models highlight the potential of this strategy.

Squids' birthday influences mating

The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.
