Nearly pain-free microneedle patch can test for antibodies and more in the fluid between cells. Medical researchers have developed a biosensing microneedle patch that can be applied to the skin, capture a biomarker of interest and, thanks to its unprecedented sensitivity, allow clinicians to detect its presence.

Blood draws are no fun. They hurt. Veins can burst, or even roll — like they’re trying to avoid the needle, too...

A unique six-planet system, 200 light years away from Earth, has been observed around the star TOI-178 by an international research team including scientists from the University of St Andrews.

The observations were made using the CHEOPS (Characterising ExOPlanets Satellite) space telescope that was launched in December 2019 with the important goal of precisely measuring the size of known planets. However, as this work finds, the spacecraft has the exciting potential to discover new planets.

CHEOPS is a joint mission by the European Space Agency (ESA) and Switzerland, under the aegis of the University of Bern in collaboration with the University of Geneva and the University of St Andrews.

The team had believed there ...

The Sun’s extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.

One explanation is that, in the middle layer (the chromosphere), magnetic waves exert a force that separates the Sun’s plasma into different components, so that only the ion particles are transported into the corona, while leaving neutral particles behind (thus leading to a build-up of elements such as iron, silicon and magnesium in the outer atmosphere).

Now, in a new study published in The Astrophysical Journal, researchers combined observations from a telescope in New Mexico, the United States, with satellites located near Earth to identify a link between magnetic waves in the chromosphere and area...

Researchers in WMG at the University of Warwick, in collaboration with Imperial College London, have found a way to enhance hybrid flow batteries and their commercial use. The new approach can store electricity in these batteries for very long durations for about a fifth the price of current technologies, with minimal location restraints and zero emissions.

The researchers enhanced three hybrid flow cells using nitrogen doped graphene (exposed to nitrogen plasma) in a binder-free electrophoresis technique (EPD).

Wind and solar power are increasingly popular sources for renewable energy. Unfortunately, intermittency issues keep them from connecting widely to the National grid...
