THYME project discovers a sub-Neptune exoplanet orbiting young star

Astronomers report the discovery of a new sub-Neptune exoplanet as part of the TESS Hunt for Young and Maturing Exoplanets (THYME) program. The newly found alien world, designated HD 110082 b, is about three times larger than the Earth and orbits a relatively young star. The finding is reported in a paper published February 11 on arXiv.org.

Russian cargo ship docks at International Space Station

An unmanned Russian cargo ship docked at the International Space Station Wednesday with a load of supplies.

This is what happens to spacecraft when they re-enter the Earth's atmosphere

When one of the Russian Progress resupply ships undocks from the International Space Station, timing is everything. The Progress needs to fire its engines at just the right time to instigate the deorbit burn in order for the ship to enter the atmosphere at just the right place so that its destructive re-entry occurs over the Pacific Ocean. That way, any potential surviving bits and pieces that might reach Earth will hit far away from any land masses—which are home to people, buildings, and other things we don't want to get bonked.

Tactile avatar: Tactile sensing system mimicking human tactile cognition

Tactile avatar is an artificial tactile perception and cognition system used as a surrogate for human tactile cognition with potential to produce smooth or soft and rough tactile sensations by its user. In a new report now published on Advanced Science, researchers used a piezoelectric tactile sensor to record varying physical information including pressure, temperature, hardness, sliding velocity and surface topography. In this work, Kyungsoo Kim and a team of scientists in information and communication engineering, neurology, brain and cognitive sciences in Korea engineered artificial tactile cognition by testing the tactile feelings of human participants to a variety of materials ranging from smooth or soft to rough. To account for the response variation among humans, Kim et al. designed a deep learning structure for personalization through training based on individualized histograms of tactile cognition while recording physical tactile information. The decision error of each avatar system was less than 2% for 42 different types of materials, where tactile data could be measured with 100 trials for each material. The tactile avatar machine categorized new experiences of materials based on the knowledge of the tactile training data to show a high correlation with the specific user's approach. The scientists intend to propose an advanced method with tactile emotional exchange capabilities for advanced digital experiences in electronic devices.

Walking quadruped is controlled and powered by pressurized air

Engineers at the University of California San Diego have created a four-legged soft robot that doesn't need any electronics to work. The robot only needs a constant source of pressurized air for all its functions, including its controls and locomotion systems.

Power outages across the Plains: 4 questions answered about weather-driven blackouts

Energy expert Michael E. Webber explains why weather extremes can require such extreme steps.

Underwater soft robot inspired by the brittle star

Soft robots are better suited to certain situations than traditional robots. When interacting with an environment, humans or other living things, the inherent softness built into the structure of a robot made of rubber, for example, is safer than metal. Soft robots are also better at interacting with an unstable or uncertain environment—if a robot contacts an unpredicted object, it can simply deform to the object rather than crashing.

Underwater robots are key to understanding and protecting deep-water species

A new study shows that the combined use of fixed acoustic reception stations and underwater robots for the study of deep-sea species allows for a better understanding of their ecology. These technological advances could improve the recovery of deep-sea demersal populations.

Blockchain-based copyright protection

Blockchain is a decentralized technology used to protect the security and privacy of online transactions and is usually associated with cryptocurrencies such as Bitcoin. However, it can be applied to all kinds of digital exchanges. In a new study, Amna Qureshi and professor David MegĂ­as, director of the IN3, analyzed existing blockchain-based multimedia content protection systems and established a taxonomy to classify them according to their technical features, the protection techniques they use and their performance. The study is the first detailed analysis of this type of application and looks at the technological and scientific challenges for their improvement and implementation.

Wearable microfluidic sensor to measure lactate concentration in real time

With the seemingly unstoppable advancement in the fields of miniaturization and materials science, all sorts of electronic devices have emerged to help us lead easier and healthier lives. Wearable sensors fall in this category, and they have received much attention lately as useful tools to monitor a person's health in real time. Many such sensors operate by quantifying biomarkers, that is, measurable indicators that reflect one's health condition. Widely used biomarkers are heartrate and body temperature, which can be monitored continuously with relative ease. On the contrary, chemical biomarkers in bodily fluids, such as blood, saliva, and sweat, are more challenging to quantify with wearable sensors.
