As 3D printing continues to transform manufacturing, doctors are hoping it could also help the 30 million people worldwide in need of artificial limbs and braces
When it comes to growing intestines, the first inch is the hardest—especially in a petri dish. Scientists at Cincinnati Children’s Hospital Medical Center have met that benchmark: they recently reported in Nature Medicine that they had grown a piece of gut—nerves, muscles and all—from a single line of human stem cells. In the future such tissue could be used for studying disease and more.
Microscopic machines that swim through the bloodstream to deliver drugs or perform minor surgeries have been a dream of scientists for decades. In the past 15 years researchers have created micro-engine variants that rely on chemical reactions, magnetism or vibration for thrust—but they often motor around erratically. The main challenge is guiding them to where they are needed

New details of the aging process have been uncovered by a research team. They discovered an altered balance between certain signaling molecules in the smooth muscle cells of blood vessels and the heart. The team also discovered a new class of drugs that combats an important part of the aging process.
Robotic movement sensing systems in the homes of elderly people can predict with a high level of accuracy when a person is at high risk of having a fall and send warnings to support workers or relatives, say researchers
Artificial intelligence has a new job: setting a good example for your kids. It seems that children’s behaviour can be influenced by the personality of a robot companion – playing with an enthusiastic or attentive robot, for instance, made them engage more and work harder.
Earlier this month, a company named Agility Robotics unveiled its first ever robot: a bipedal creation named Cassie that looks like a headless, wingless ostrich. Cassie has reverse knees, motor-powered ankles, and can walk over different sorts of terrain at a decent clip.

In 2015 UC Santa Barbara mechanical engineer and materials scientist Jonathan Berger developed an idea that could change the way people think about high-performance structural materials. Two years later, his concept is paying research dividends.
Although scientists have been able to levitate specific types of material, a pair of UChicago undergraduate physics students helped take the science to a new level.
Third-year Frankie Fung and fourth-year Mykhaylo Usatyuk led a team of UChicago researchers who demonstrated how to levitate a variety of objects—ceramic and polyethylene spheres, glass bubbles, ice particles, lint strands and thistle seeds—between a warm plate and a cold plate in a vacuum chamber.
The invasive Brazilian peppertree contains a substance that keeps drug-resistant bacteria from producing their deadly toxins.

Powerful gene editing procedures could one day be allowed to prevent people from passing on serious medical conditions to their children, according to a major report from senior US researchers.
To push the city toward a more eco-friendly future, Brussels is planning to build three vertical structures using recyclable materials, renewable energy sources, and 30,000 plants.
This plan to redefine the urban landscape using nature is one of many being undertaken by cities across the globe, and it could prove very beneficial to the environment.
Imagine patterning and visualizing silicon at the atomic level, something which, if done successfully, will revolutionize the quantum and classical computing industry. A team of scientists has done just that, led by a world-renowned physicist and his up-and-coming protégé.
A heat-reflecting, futuristic supermaterial that looks like a roll of plastic wrap could one day cool both houses and power plants without using any energy, according to a new study.
In the future, wide-ranging composite materials are expected to be stronger, lighter, cheaper and greener for our planet, thanks to a new invention. Nine years ago, an American researcher invented an energy-efficient technology that harnesses largely low-temperature, water-based reactions.

A tsunami’s immense wall of water may not be stoppable. But there may be a way to take the ferocious force of nature down a few notches, using a pair of counterwaves.
If released at the right moment, a type of sound wave known as an acoustic-gravity wave could subdue a tsunami
Temperatures are now so high at the north pole that scientists are contemplating radical schemes to avoid catastrophe
