Three ways to travel at (nearly) the speed of light

One hundred years ago today, on May 29, 1919, measurements of a solar eclipse offered verification for Einstein's theory of general relativity. Even before that, Einstein had developed the theory of special relativity, which revolutionized the way we understand light. To this day, it provides guidance on understanding how particles move through space—a key area of research to keep spacecraft and astronauts safe from radiation.

Sensor-packed glove learns signatures of the human grasp

Wearing a sensor-packed glove while handling a variety of objects, MIT researchers have compiled a massive dataset that enables an AI system to recognize objects through touch alone. The information could be leveraged to help robots identify and manipulate objects, and may aid in prosthetics design.

Outsmarting deep fakes: AI-driven imaging system protects authenticity

To thwart sophisticated methods of altering photos and video, researchers at the NYU Tandon School of Engineering have demonstrated an experimental technique to authenticate images throughout the entire pipeline, from acquisition to delivery, using artificial intelligence (AI).

Men who choose active surveillance for early prostate cancer often don't follow monitoring rules

Preliminary results from a University of North Carolina Lineberger Comprehensive Cancer Center study found that just 15 percent of a group of men in North Carolina with early-stage prostate cancer who choose active surveillance instead of treatment followed the recommended monitoring guidelines.

Research reveals role of fat storage cells in anti-obesity intervention

New research from a team at the Marshall University Joan C. Edwards School of Medicine establishes a role of adipocyte Na/K-ATPase signaling in worsening obesity and its companion diseases, including neurodegeneration and non-alcoholic steatohepatitis (NASH), that was enhanced by specific targeting of NaKtide, an antagonist of Na/K-ATPase signaling, to the adipocyte.

Excess cause-specific mortality tied to chronic proton pump inhibitor use

(HealthDay)—Taking proton pump inhibitors (PPIs) is associated with an excess of cause-specific mortality, according to a study published online May 30 in The BMJ.

More than half of patients in pain management study took no opioids after operations

The opioid epidemic has become a public health crisis in the U.S. While primary care physicians have been writing fewer opioid prescriptions over the last several years, new opioid prescriptions by surgeons increased 18 percent from 2010-2016. However, many surgeons are now diligently working to change their prescribing practices. One approach has been to try reducing excessive opioid prescriptions by exploring pain management strategies that include fewer or no opioids at all for surgical patients.

Quick liquid packaging: Encasing water silhouettes in 3-D polymer membranes for lab-in-a-drop experiments

The ability to confine water in an enclosed compartment without directly manipulating it or using rigid containers is an attractive possibility. In a recent study, Sara Coppola and an interdisciplinary research team in the departments of Biomaterials, Intelligent systems, Industrial Production Engineering and Advanced Biomaterials for Healthcare in Italy, proposed a water-based, bottom-up approach to encase facile, short-lived water silhouettes in a custom-made adaptive suit.

Nailing digital fakes with AI-learned artifacts

We see the imaginative feats of photo fakery; now we have to figure out what to do about them. Being able to tell fake from real is the goal, but how to get there? Forensics is the key tool to hunt down fake photos and it does not appear to be an easy task in getting that tool to perform well.

A deep neural network that can maximize or minimize coloring to blend into or stand out against a background

A team of researchers at the University of Bristol has developed a deep learning neural network that can identify the best way to minimize or maximize coloring to allow for blending into a background or standing out. In their paper published in Journal of the Royal Society Interface, the team describes their network and possible uses for it.

Nature's first aid kit: A fungus growing on the sides of birch trees

If you've ever stopped to admire a birch tree, you may unknowingly have something in common with a 5,300-year-old mummy called Ötzi. In 1991, hikers found Ötzi in an alpine glacier on the Austrian-Italian border, and perfectly preserved with him were pieces of fungus attached to leather cords, safely stowed in his bag. That fungus is the same one you can see growing on birch trees today: the birch polypore.

The most complete study of battery failure sees the light

An international team of researchers just published in Advanced Energy Materials the widest study on what happens during battery failure, focusing on the different parts of a battery at the same time. The role of the ESRF, the European Synchrotron, in France, was crucial for its success.

Electrified methane reformer produces far less carbon dioxide

A team of researchers from several institutions in Denmark, along with colleagues from Sintex and Haldor Topsoe, has developed an electrified methane reformer that produces far less CO2 than conventional steam-methane reformers. In their paper published in the journal Science, the group describes their new technology and how well it works. Kevin Van Geem, Vladimir Galvita and Guy Marin with the Laboratory for Chemical Technology and Center for Sustainable Chemistry in Ghent have published a Perspective piece on the work done by the team in the same journal issue.
