Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new record for the most extreme range of orbits yet observed: the outermost planet is more than a thousand times further from the star than the innermost one, which raises interesting questions about how such a system might have formed.

The star is just two million years old – a ‘toddler’ in astronomical terms – and is surrounded by a huge disc of dust and ice...

Researchers at the University of Sussex have become the first in the world to develop technology which can bend sound waves around an obstacle and levitate an object above it. SoundBender, developed by Professor Sriram Subramanian, Dr Gianluca Memoli and Dr Diego Martinez Plasencia at the University of Sussex, is an interface capable of producing dynamic self-bending beams that enable both levitation of small objects and tactile feedback around an obstacle.

The technology, to be presented at the 31st ACM User Interface Software and Technology Symposium in Berlin this Monday [October 15], overcomes two key limitations of previous ultrasound levitation set-ups, which were ...

After 11 months of dupilumab treatment, significant pigmented hair has grown across the patient’s scalp.

Massachusetts General Hospital (MGH) physicians are reporting an unexpected side-effect from treatment with dupilumab, which is FDA approved for the treatment of moderate to severe eczema, also called atopic dermatitis. In their case report published in JAMA Dermatology, the physicians describe how their 13-year-old patient, who has alopecia totalis – a total lack of scalp hair – along with eczema, experienced significant hair regrowth while being treated with dupilumab, a drug marketed under the brand name Dupixent.

“We were quite surprised since this patient hadn’t grown scalp hair since the age of 2, and other treatments that can help with hair loss did not in her case,” says Marya...

Diagrammatic comparison of our bioinspired high-dynamic-range polarization camera with its biological counterpart, the mantis shrimp ommatidium.

New camera mimics mantis shrimp vision to significantly improve dynamic range and add polarization information. Inspired by the visual system of the mantis shrimp – among the most complex found in nature – researchers have created a new type of camera that could greatly improve the ability of cars to spot hazards in challenging imaging conditions.

The new camera accomplishes this feat by detecting a property of light known as polarization and featuring a dynamic range about 10,000 times higher than today’s commercial cameras. Dynamic range is a measure of the brightest and darkest areas a camera can capture simultaneously...
