Researchers have created a new type of tiny 3D-printed robot that moves by harnessing vibration from piezoelectric actuators, ultrasound sources or even tiny speakers. Swarms of these “micro-bristle-bots” might work together to sense environmental changes, move materials – or perhaps one day repair injuries inside the human body.
Rising temperatures in the tundra of the Earth’s northern latitudes could affect microbial communities in ways likely to increase their production of greenhouse gases methane and carbon dioxide, a new study of experimentally warmed Alaskan soil suggests.
Instability hidden within Antarctic ice is likely to accelerate its flow into the ocean and push sea level up at a more rapid pace than previously expected. Even if images of vanishing Arctic ice and mountain glaciers are jarring, their potential contributions to sea level rise are nowhere near Antarctica’s.
By energizing precursor molecules using a tiny, high-energy supersonic jet of inert gas, researchers have dramatically accelerated the fabrication of nanometer scale structures. The rapid additive manufacturing technique also allows them to produce structures with high aspect ratios. Now, a theory developed to describe the technique could lead to new applications for additive nanomanufacturing and new nanoscale materials.

Those same antibiotics driving antibiotic resistance could also help defeat it if used with the right strategy. Making it work would require companion health strategies like staying home from work when carrying resistant bacteria.
Atomic beams conjure fantasies of gigantic Space Force canons. But there are real tiny atomic beams that shoot out of newly engineered collimators, a kind of tiny silicon peashooter, that could land in handheld devices. The beams streaming out of them create precise inertia much better than a gyroscope's that could help spacecraft navigate the solar system. The atomic beams from the new collimators could also let physicist cheaply and easily produce exotic quantum mechanical states.

Needle biopsies detect rejection after a transplanted organ is already in trouble and sometimes miss the mark. And the needle damages tissue. This biocompatible nanoparticle goes to work at the first sign of trouble and could give clinicians much more information with a simple urine test.
Myocardial infarction, a-fib, congestive heart failure, coronary artery disease, and more could be detected early and more easily and effectively treated with these six emerging solutions.
Artificial Intelligence is helping to guide and support some 50 breast cancer patients in rural Georgia through a novel mobile application that gives them personalized recommendations on everything from side effects to insurance.
Here's a science enigma: Try to explain where the neat, even DNA/RNA helix came from. Ha! Easy one! It probably spun around itself long before first life evolved like it did in this lab. In fact, the twist could have helped select the components of RNA, not the other way around.
An international research team has shown that when galaxies assemble extremely rapidly -- and sometimes violently -- that can lead to the formation of very massive black holes. In these rare galaxies, normal star formation is disrupted and black hole formation takes over.
As coral species die off, they may be leaving a death spiral in their wake: Their absence could be sapping life from the corals that survive. In a new study, when isolated from other species, corals got weak, died off or grew in fragile structures. The study shows it is possible to quantify positive effects of coral biodiversity and negative effects of its absence.
A new wave of semiconductors that can be painted on is on the horizon. It bears the promise of revolutionizing lighting all over again and of transforming solar energy. Ornate quantum particle action, revealed here, that drives the new material's properties defies the workings of established semiconductors.
A new long-acting contraceptive designed to be self-administered by women may provide a new family planning option, particularly in developing nations where access to healthcare can be limited, a recent study suggests. The contraceptive would be delivered using microneedle skin patch technology originally developed for the painless administration of vaccines.

The new fuel cell, which provides twice as much power as conventional biofuel cells, could be paired with batteries or supercapacitors to provide a hybrid power source for the medical devices.
What if we could observe genes firing off signals to cause some behaviors? We're getting closer. Researchers were able to directly match gene regulation with ritual mating behavior in fish. Their research field may also give some insight into autism spectrum disorder.
The mechanisms that trigger the elimination of T cells that pose autoimmune dangers work very mechanically via physical forces. Nascent T cells must loosen their grip on human antigens within a reasonable time, in order to advance and defend the body. But if the nascent T cells, thymocytes, grip the human antigens too tightly, the immune cells must die. Here's how the grip of death works.
This experiment had a good chance of crashing. Instead, it delivered whopping evidence to corroborate that the translational system, which makes life out of our genes, would have thrived basically as it is today 4 billion years ago at the earliest foundations of life on Earth.
