Treeswift's Autonomous Robots Take Flight to Save Forests
Forests cover 30% of the Earth's landmass, but that number is on the decline. Despite forests' crucial role in conserving wildlife and processing carbon dioxide, many are threatened by deforestation and wildfires. Complicating these threats is the lack of quantitative information that foresters and environmental researchers need for making important decisions to preserve forests.

AI Keeps an Eye on Volcano Movements
Radar satellites can collect massive amounts of remote sensing data that can detect ground movements at volcanoes in near real time. These ground movements could signal impending volcanic activity and unrest; however, clouds and other atmospheric and instrumental disturbances can introduce significant errors in those ground movement measurements. Now, researchers have used artificial intelligence to clear up that noise, drastically facilitating and improving near real-time observation of volcanic movements and the detection of volcanic activity and unrest.

Engineers Print Wearable Sensors Directly on Skin Without Heat
Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.

Using Wearable Technology to Prevent Kidney Stones
Kidney stones are a painful and expensive medical problem, and people who suffer from kidney stones once are likely to experience them a second time. Recurrence can often be prevented if patients increase urine output by increasing the amount of water that they drink. Though this may seem easy, fewer than 50% of people who have suffered from kidney stones are able to drink the recommended amount of fluids.

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.

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.

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.
