MobiKa: A low-cost mobile robot that can assist people in a variety of settings

Researchers at Fraunhofer IPA, in Stuttgart, Germany, have recently developed MobiKa, a low-cost, mobile robot capable of two-modal (voice and text) interactions with humans. Their robot, presented in a paper pre-published on arXiv, could be particularly useful for assisting elderly people.

A gut check for heart failure patients

Heart failure patients who consume more dietary fibre tend to have healthier gut bacteria, which is associated with reduced risk of death or need of a heart transplant. The fibre study was presented today at Heart Failure 2019, a scientific congress of the European Society of Cardiology (ESC).

Zero-carbon electric transport is already in reach for small islands

At a recent talk on the UK's energy sector, the head of an electric utility company claimed that "the problem of decarbonising our electricity sector is fixed". Eyebrows were raised at this, but his point quickly became clear. The technologies needed to decarbonise the UK's electricity system now exist, he explained. Indeed, grid operators in the UK expect a zero carbon electricity system by 2025.

Mobile phone app designed to boost physical activity in women shows promise in trial

Activity trackers and mobile phone apps are all the rage, but do they really help users increase and maintain physical activity? A new study has found that one mobile phone app designed for inactive women did help when combined with an activity tracker and personal counseling.

NASA's Mars 2020 mission drops in on Death Valley

On a test flight in Death Valley, California, an Airbus helicopter carried an engineering model of the Lander Vision System (LVS) that will help guide NASA's next Mars mission to a safe touchdown on the Red Planet. During the flight - one in a series—the helicopter (which is not part of the mission and was used just for testing) and its two-person crew flew a pre-planned sequence of maneuvers while LVS collected and analyzed imagery of the barren, mountainous terrain below.

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.

CycleMatch: a new approach for matching images and text

Researchers at Leiden University and the National University of Defense Technology (NUDT), in China, have recently developed a new approach for image-text matching, called CycleMatch. Their approach, presented in a paper published in Elsevier's Pattern Recognition journal, is based on cycle-consistent learning, a technique that is sometimes used to train artificial neural networks on image-to-image translation tasks. The general idea behind cycle-consistency is that when transforming source data into target data and then vice versa, one should finally obtain the original source samples.

Three convolutional neural network models for facial expression recognition in the wild

Two researchers at Shanghai University of Electric Power have recently developed and evaluated new neural network models for facial expression recognition (FER) in the wild. Their study, published in Elsevier's Neurocomputing journal, presents three models of convolutional neural networks (CNNs): a Light-CNN, a dual-branch CNN and a pre-trained CNN.

Paper stickers to monitor pathogens are more effective than swabs

Using paper stickers to collect pathogens on surfaces where antisepsis is required, such as in food processing plants, is easier, and less expensive than swabbing, yet similarly sensitive. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

100% renewables doesn't equal zero-carbon energy, and the difference is growing

While 160 companies around the world have committed to use "100 percent renewable energy," that does not mean "100 percent carbon-free energy." The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study published today in Joule. Entities committed to fighting climate change can and should measure the environmental benefits of their renewable strategies accurately, the authors write.
