Researchers have compiled a dataset that captures the detailed behavior of a robotic system physically pushing hundreds of different objects. Using the dataset — the largest and most diverse of its kind — researchers can train robots to 'learn' pushing dynamics that are fundamental to many complex object-manipulation tasks, including reorienting and inspecting objects, and uncluttering scenes.
Read moreNext-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term 'green technology.' Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency of the devices in a series of laboratory tests, according to an international team of researchers.
Read moreBioscience engineers have developed a method to measure the snow depth in all mountain ranges in the Northern Hemisphere using satellites. This technique makes it possible to study areas that cannot be accessed for local measurements, such as the Himalayas.
Read moreA new study is the first to compare professional electronic sport (esport) players with recreational video game players and explores the similarities and differences between what motivates each group. While the two groups are psychosocially different, they found that both esport and recreational gamers run the risk of developing internet gaming disorder when their intense immersion in the activity is tied to escapism.
Read moreIntroducing tablets and laptops to the classroom has certain educational virtues, according to one researcher, but her research suggests that tech has its limitations as well. A new study shows a decrease in academic motivation for students who participated in a technology-based intervention.
Read moreSwapping a single amino acid in a simple bacterial protein changes its structure and function, revealing the effects of complex gene evolution, finds a new study. The study — conducted using E. coli bacteria — can help researchers to better understand the evolution of transporter proteins and their role in drug resistance.
Read moreResearchers have developed an open-source tool that allows users to track and record the behavior of JavaScript programs without alerting the websites that run those programs. The tool, called VisibleV8, runs in the Chrome browser and is designed to detect malicious programs that are capable of evading existing malware detection systems.
Read moreA team of psychology researchers is providing one of the first comprehensive literature reviews on arrogance, as well as a way to classify the condition on different levels across a spectrum, similarly to how autism is diagnosed. The team acknowledges everyone seems to have some degree of arrogance, so in addition to the literature review, the researchers suggest a way to classify the different levels of arrogance a person could exhibit.
Read moreIn clinical trials of adults with Huntington's disease (HD) the Q-Suite Motor Assessment Tool (Q-Motor) has proven to be helpful to detect and quantitate subtle motor abnormalities. With the anticipated arrival of preventive gene therapies that will most likely be administered to young children known to be carriers of the HD mutation, it is crucial to have a means to evaluate motor abilities in children that is sensitive to the child's stage of development.
Read moreScientists have developed a forensic tracer that uses lead isotopes to detect and measure coal fly ash in dust, soil and sediments. Tests show the new tracer can distinguish between the isotopic signature of lead derived from coal ash and lead that comes from other major human or natural sources. Exposure to fly ash from dust, soil or sediments has been linked to numerous diseases and health concerns.
