There is a critical need for non-invasive solutions to monitor heart failure progression around the clock. This novel wearable device is based on sensors embedded in a lightweight belt that monitors thoracic impedance, electrocardiogram (ECG), heart rate and motion activity detection. The device was tested in different conditions including sitting, standing, lying down and walking. Findings showed that all of sensors kept track of the changes for all of the different conditions.

Using a new analytical method, Empa researchers have tracked viruses as they pass through face masks and compared their failure on the filter layers of different types of masks. The new method should now accelerate the development of surfaces that can kill viruses, the team writes in the journal Scientific Reports.

The precise relationship between vaccine hesitancy and COVID-19 vaccination side effects has not previously been explored in vaccinated persons. A fundamental question arises in regard to the directionality of this vaccine hesitancy-vaccine side effect link, namely which variable predicts which. One possibility is that side effects from an earlier dose predict one’s vaccine hesitancy towards a later dose. Alternatively, one’s psychological negativity (hesitancy) towards an earlier dose could predict subsequent side effects from a later vaccination dose. The latter direction reflects a Nocebo effect, i.e., side effects driven by psychological factors rather than by an active treatment component. Results showed only the latter direction to be true. Namely, only earlier vaccine hesitancy towards the second COVID-19 dose predicted subsequent nocebo side-effects following the booster vaccination. To put this in perspective up to 16% of one’s vaccine side effects were explained by earlier va
While most animals don’t learn their vocalizations, everyone knows that parrots do – they are excellent mimics of human speech. Researchers aim to add to what we know about animal vocal learning by providing the largest comparative analysis to date of parrot vocal repertoires.

Collaborative research between SMU nanorobotics authority MinJun Kim’s Biological Actuation, Sensing, and Transport (BAST) Lab and international research and engineering company ARA has demonstrated for the first time that certain chemical coatings, applied to micro/nanoparticles, can alter their swimming propulsion within biological fluids.
Volcanic eruptions are dangerous and difficult to predict. A team at the University of Tokyo has found that the ratio of atoms in specific gases released from volcanic fumaroles (gaps in the Earth’s surface) can provide an indicator of what is happening to the magma deep below — similar to taking a blood test to check your health.
Capuchin monkeys (Sapajus spp.) are among only a few primates that use tools in day-to-day activities.
Engineers and physicians at UC San Diego have developed a device to non-invasively measure cervical nerve activity in humans, a new tool they say could potentially inform and improve treatments for patients with sepsis or post-traumatic stress disorder.
Our sensory urges ranging from anger to hunger are regulated by hormonal or neuronal signals. Often, these impulses appear as behavioral responses, evoked through complex biological reactions.
The researcher and GRS Radioisotopes technician from the University of Seville, Jorge Rivera, has participated in an incredible discovery that is unique in Europe.
A delicacy in Japanese cuisine, puffer fish (fugu) also contain a lethal toxin.
Understanding how active, healthy ageing can be achieved is one of the most relevant problems today. Dogs can be used as model animals for studying ageing, and their welfare is also a public concern.

A new study led by researchers from the National University of Singapore revealed that variation in primate eye colouration is partly due to differences in lighting in the habitats of primate species. This helps tip the balance towards an ecological, rather than sexual selection explanation, for the evolution of blue eye colour in humans.
Modern humans may have co-existed with Neanderthals in France and northern Spain for between 1,400 and 2,900 years before Neanderthals disappeared, according to a modelling study published in Scientific Reports.

Since becoming available, vaccines against COVID-19 have been vital in preventing deaths.
Combining microbiology with engineering technologies, this novel 3D model uses a single microfluidic chip to study the complicated processes that take place in malaria-infected placenta as well as other placenta-related diseases and pathologies. The technology supports formation of microengineered placental barriers and mimics blood circulations, which provides alternative approaches for testing and screening.
Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now.
With autocorrect and auto-generated email responses, algorithms offer plenty of assistance to help people express themselves. But new research from the University of Georgia shows people who rely on algorithms for assistance with language-related, creative tasks didn’t improve their performance and were more likely to trust low-quality advice.
