Animals first flex their muscles

A 560-million-year-old fossil discovery in Newfoundland, Canada, has provided the oldest evidence of muscle tissue in animals. The find, named Haootia quadriformis, is a rare example of an Ediacaran animal with bundles of fibres similar to those found in modern cnidarians.

Children's Hospital of Philadelphia reports on 100 recent fetal surgeries for spina bifida

The Children's Hospital of Philadelphia has reported successful results from 100 recent cases of fetal surgery for spina bifida, achieving comparable outcomes to the landmark MOMS trial. The study found improved rates of shunting and pulmonary edema, as well as shorter operative times and decreased transfusion rates.

Social inequalities in salt consumption remain

A study published in BMJ Open found that social inequalities in salt intake have hardly changed in Britain over the last decade, despite a national average salt reduction. The research suggests that poorer households still consume more salt than higher socio-economic groups, highlighting the need to address these disparities to achieve...

A glucose meter of a different color provides continuous monitoring

Researchers developed a new continuous glucose monitoring material that changes color as glucose levels fluctuate, offering higher sensitivity and precision than current point measurements. The color-changing material is simple, low-cost to manufacture, and can be used for short-term monitoring of patients in intensive care units.

Competition for graphene

Researchers at Berkeley Lab have observed ultrafast charge transfer in MX2 materials, a new family of 2-D semiconductors. The recorded charge transfer time is comparable to the fastest times for organic photovoltaics, opening up potentially rich new avenues for photonics and optoelectronics.

New statin guidelines an improvement, Yale study shows

A Yale University study found that new national guidelines can accurately prescribe statins to patients at risk for cardiovascular disease. The research shows the new guidelines produce a modest increase in patient treatment, with only 92% of those with heavy plaque being assigned to statin therapy under the new method.

Tilted acoustic tweezers separate cells gently

Researchers have developed a device that uses tilted-angle standing surface acoustic waves to separate cells with minimal energy. The method is gentler than traditional methods like centrifugation and can efficiently sort cells with high purity.

Key to universal flu vaccine: Embrace the unfamiliar

A new strategy for generating broadly cross-reactive antibodies has been developed against the H5N1 flu virus. Researchers found that human volunteers immunized with the H5N1 virus generated antibodies against the stem region of the viral hemagglutinin protein, which could provide protection against a variety of flu strains.
