Laser Jolts Microscopic Electronic Robots into Motion

In 1959, former Cornell physicist Richard Feynman delivered his famous lecture "There's Plenty of Room at the Bottom," in which he described the opportunity for shrinking technology, from machines to computer chips, to incredibly small sizes. Well, the bottom just got more crowded

Soft Robot Actuators Heal Themselves

Repeated activity wears on soft robotic actuators, but these machines' moving parts need to be reliable and easily fixed. Now a team of researchers has a biosynthetic polymer, patterned after squid ring teeth, that is self-healing and biodegradable, creating a material not only good for actuators, but also for hazmat suits and other applications where tiny holes could cause a danger.

In East Africa, a Race to Outsmart Locusts with Drones and Data

While the eyes of the world are on the novel coronavirus, East Africa continues to struggle with another crisis of biblical proportions: growing swarms of ravenous locusts. Both crises are extraordinary in scale, and both foes multiply so quickly that governments are struggling to contain them.

Scavenger Technology Allows Robots to Eat Metal for Energy

When electronics need their own power sources, there are two basic options: batteries and harvesters. Batteries store energy internally, but are therefore heavy and have a limited supply. Harvesters, such as solar panels, collect energy from their environments. This gets around some of the downsides of batteries but introduces new ones, in that they can only operate in certain conditions and can't turn that energy into useful power very quickly.

Scientists Tap Unused Energy Source to Power Smart Sensor Networks

The electricity that lights our homes and powers our appliances also creates small magnetic fields that are present all around us. Scientists have developed a new mechanism capable of harvesting this wasted magnetic field energy and converting it into enough electricity to power next-generation sensor networks for smart buildings and factories.

CRISPR Could be Feasible for Fighting Cancer

Genetically-edited immune cells can persist, thrive, and function months after a cancer patient receives them, according to new data published by researchers. The team showed cells removed from patients and brought back into the lab setting were able to kill cancer months after their original manufacturing and infusion.

Design Approach May Help Fix Bias in Artificial Intelligence

Bias in artificial intelligence and machine learning programs is well established. Researchers are now proposing that software developers incorporate the concept of "feminist design thinking" into their development process as a way of improving equity - particularly in the development of software used in the hiring process.

Engineers Mix and Match Materials to Make New Stretchy Electronics

At the heart of any electronic device is a cold, hard computer chip, covered in a miniature city of transistors and other semiconducting elements. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.

Self-Healing Liquid Brings New Life to Battery Alternative

Rechargeable lithium-ion batteries are a revolutionary technology, found in everything from cellphones to cars. But the chemistry behind them is facing a looming challenge. Lithium-ion batteries cannot be recharged indefinitely; the materials in these batteries' electrodes expand and crack with each cycle, gradually decreasing their storage performance until they are useless. The resulting demand for fresh lithium, cobalt and other necessary elements puts a strain on natural resources.

Computer Generated Antibiotics, Biosensor Band-Aids

Imagine if a computer could learn from molecules found in nature and use an algorithm to generate new ones. Then imagine those molecules could get printed and tested in a lab against some of the nastiest, most dangerous bacteria out there—bacteria quickly becoming resistant to our current antibiotic options.
