A multi-camera optical tactile sensor that could enable vision-based robotic skins

A team of researchers at ETH Zurich in Switzerland has recently developed a multi-camera optical tactile sensor (i.e., a tactile sensor based on optical devices) that collects information about the contact force distribution …

Tropical fish shredding kelp forests in temperate zones

Climate change is causing previously temperate oceans to become more tropical with coral reef fish moving south, settling in and changing how things work in their new temperate neighborhood, according to a study by The University …

Cells lose their ability to share resources as we get older

A research team led by The University of Western Australia has found that our cells deteriorate and share fewer resources as we age, which can lead to the onset of diseases such as osteoporosis, arthritis, cardiovascular …

Decoding the fundamental mechanisms of human salivary lubrication

An interdisciplinary team of scientists led by the University of Leeds have uncovered the fundamental mechanism by which human saliva lubricates our mouth. Their multi-scale study opens the door to advancing dry mouth therapies …

The antibiotic arms race moves at high speed

Acinetobacter baumannii is a pathogen that creates serious problems in hospitals throughout the world. It causes opportunistic infections in the bloodstream, urinary tract, and other soft tissues, accounting for as much as …

Researchers sequence genome of the ‘devil worm’

When scientists discovered a worm deep in an aquifer nearly one mile underground, they hailed it as the discovery of the deepest-living animal ever found. Now American University researchers, reporting in Nature Communications, …

Scientists first to develop rapid cell division in marine sponges

Vertebrate, insect, and plant cell lines are important tools for research in many disciplines, including human health, evolutionary and developmental biology, agriculture and toxicology. Cell lines have been established for …

New hybrid device can both capture and store solar energy

Researchers from the University of Houston have reported a new device that can both efficiently capture solar energy and store it until it is needed, offering promise for applications ranging from power generation to distillation …

Magnetic wave flows under better control from now on

Even faster processors with even smaller dimensions? Wherever neither electronics nor spintronics can cope with performance or miniaturization, magnonics comes to the rescue. But before that happens, scientists must learn …

Fractured ice sheets on Mars

Where the two hemispheres of Mars meet, the planet is covered in broken-up terrain: a sign that slow-but-steady flows of icy material once forged their way through the landscape, carving out a fractured web of valleys, cliffs …

Eliminating cracks in 3-D-printed metal components

Researchers at EPFL have developed a new laser 3-D-printing technique to manufacture metal components with unprecedented resistance to high temperature, damage and corrosion. The method has applications in fields ranging …

Unlocking the power of sulfur in future drug design

Organosulfur compounds are widely present in our bodies and the natural environment. They are found in onions, shallots and even cauliflower. Medical research finds that when consumed, they can protect against cancer, heart …

Digital inclusion and wellbeing in New Zealand

New research using four large-scale surveys of New Zealanders shows those in social housing and people with disabilities appear to be particularly disadvantaged with respect to internet access.

Building a Mars base with bacteria

How do you make a base on Mars? Simple: you send some bacteria to the red planet and let them mine iron. After a couple of years, you send in human settlers who use the iron to construct a base. That, in a nutshell, is the …

Researchers design an improved pathway to carbon-neutral plastics

Researchers from U of T Engineering and Caltech have designed a new and improved system for efficiently converting CO2, water, and renewable energy into ethylene—the precursor to a wide range of plastic products, from medical …

To navigate, flies make flexible mental maps of the world

In a circular arena, a fruit fly navigates a virtual landscape illuminated by black and blue lights. The fly is tethered in place, able to flap its wings but not move its head. Images on the wall rotate to give the illusion …
