Findings could lead to targeted approach for treating aging.

Research from the Babraham Institute has developed a method to ‘time jump’ human skin cells by 30 years, turning back the aging clock for cells without losing their specialized function. Work by researchers in the Institute’s Epigenetics research program has been able to partly restore the function of older cells, as well as rejuvenating the molecular measures of biological age. The research is published today (April 7, 2022) in the journal eLife and whilst at an early stage of exploration, it could revolutionize regenerative medicine.

The furious debate over Aduhelm has now sparked controversy over the Alliance for Aging Research, which has seen half of its scientific advisory board members resign.

A team of scientists has discovered how working memory is “formatted”—a finding that enhances our understanding of how visual memories are stored.

Researchers have developed a new fabrication process that allows infrared (IR) glass to be combined with another glass and formed into complex miniature shapes. The technique can be used to create complex infrared optics that could make IR imaging and sensing more broadly accessible.

“Glass that transmits IR wavelengths is essential for many applications, including spectroscopy techniques used to identify various materials and substances,” said research team leader Yves Bellouard from Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. “However, infrared glasses are difficult to manufacture, fragile and degrade easily in the presence of moisture.”

In the journal Optics Express, the researchers describe their new technique, which can be used to embed fragile IR glasses inside a durable silica matrix. The process can be used to create virtually any interconnected 3D shape with features measuring a micron or less. It works with a wide variety of glasses, offering a new way to fine-tune the properties of 3D optics with subtle combinations of glass.

A powerful radio-wave laser, called a “megamaser”, has been observed by the MeerKAT telescope in South Africa. The record-breaking find is the most distant megamaser of its kind ever detected, at about five billion light years from Earth.

The light from the megamaser has traveled 58 thousand billion billion (58 followed by 21 zeros) kilometers to Earth. The discovery was made by an international team of astronomers led by Dr. Marcin Glowacki, who previously worked at the Inter-University Institute for Data Intensive Astronomy and the University of the Western Cape in South Africa.

Dr. Glowacki, who is now based at the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) in Western Australia, said megamasers are usually created when two galaxies violently collide in the Universe.

Scientists find a sub-atomic particle’s mass is at odds with one a theory underpinning modern physics.

Physicists are using quantum math to understand what happens when black holes collide. In a surprise, they’ve shown that a single particle can describe a collision’s entire gravitational wave.

A pair of researchers working in the Personal Robotics Laboratory at Imperial College London has taught a robot to put a surgical gown on a supine mannequin. In their paper published in the journal Science Robotics, Fan Zhang and Yiannis Demiris described the approach they used to teach the robot to partially dress the mannequin. Júlia Borràs, with Institut de Robòtica i Informàtica Industrial, CSIC-UPC, has published a Focus piece in the same journal issue outlining the difficulties in getting robots to handle soft material and the work done by the researchers on this new effort.

As researchers and engineers continue to improve the state of robotics, one area has garnered a lot of attention—using robots to assist with health care. In this instance, the focus was on assisting patients in a hospital setting who have lost the use of their limbs. In such cases, dressing and undressing falls to healthcare workers. Teaching a robot to dress patients has proven to be challenging due to the nature of the soft materials used to make clothes. They change in a near infinite number of ways, making it difficult to teach a robot how to deal with them. To overcome this problem in a clearly defined setting, Zhang and Demiris used a new approach.

The setting was a simulated hospital room with a mannequin lying face up on a bed. Nearby was a hook affixed to the wall holding a surgical gown that is worn by pushing arms forward through sleeves and tying in the back. The task for the robot was to remove the gown from the hook, maneuver it to an optimal position, move to the bedside, identify the “patient” and its orientation and then place the gown on the patient by lifting each arm one at a time and pulling the gown over each in a natural way.
