RNA drugs are the next frontier of medicine, but manufacturing them requires an expensive and labor-intensive process that limits production and produces metric tons of toxic chemical waste. Researchers report a new, enzyme-based RNA synthesis method that can produce strands of RNA with both natural and modified nucleotides without the environmental hazards.

Engineers have trained a humanoid robot to perform a variety of expressive movements, from simple dance routines to gestures like waving, high-fiving and hugging, all while maintaining a steady gait on diverse terrains. This work marks a step towards building robots that perform more complex and human-like motions.

Scientists have developed a tiny ‘claw machine’ that is able to pick up and drop a marble-sized ball in response to exposure to chemical vapors. The findings point to a technique that can enable soft actuators–the parts of a machine that make it move–to perform multiple tasks without the need for additional costly materials. While

A new study suggests that giving users control over the interface feature of autoplay can help them realize that they are going down a rabbit hole. The work has implications for responsibly designing online content viewing platforms and algorithms, as well as helping users better recognize extreme content.

In a new study, researchers used low-intensity ultrasound technology to noninvasively alter a brain region associated with activities such as daydreaming, recalling memories and envisioning the future.

Without additional regulation, burning ammonia in ship engines could cause serious impacts on air quality that could result in more than 600,000 additional premature deaths per year, according to new research.

By constructing hexagonal metallic-mean approximants of the honeycomb lattice, scientists have linked incommensurately modulated structures and quasicrystals, two classes of aperiodic crystals. They found that a quasicrystal converges to a modulated honeycomb crystal on arranging tiles based on metallic means. This metallic-mean tiling pattern was also identified in polymer and colloidal systems in soft-matter self-assemblies,

How do people like to interact with robots when navigating a crowded environment? And what algorithms should roboticists use to program robots to interact with humans? These are the questions that a team of mechanical engineers and computer scientists sought to answer in a recent study.

The possibility of hydrogen-powered flight means greater opportunities for fossil-free travel, and the technological advances to make this happen are moving fast. New studies show that almost all air travel within a 750-mile radius (1200 km) could be made with hydrogen-powered aircraft by 2045, and with a novel heat exchanger currently in development, this range

A small 3-ounce sensor capable of recording 2,400 data points of movement in just one second being tested and refined by researchers could be key in reducing the number of injuries to racehorses. Researchers used the biometric sensors to track thoroughbreds as they raced and trained at some of the top racetracks in the country.
