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.

Using Artificial Intelligence to Analyse Placentas

Placentas can provide critical information about the health of the mother and baby, but only 20 percent of placentas are assessed by pathology exams after delivery in the U.S. The cost, time and expertise required to analyze them are prohibitive.

Machine Learning Algorithms Help Predict Traffic Headaches

Urban traffic roughly follows a periodic pattern associated with the typical "9 to 5" work schedule. However, when an accident happens, traffic patterns are disrupted. Designing accurate traffic flow models, for use during accidents, is a major challenge for traffic engineers, who must adapt to unforeseen traffic scenarios in real time.

Point-of-care test for prostate cancer

The proposed biosensor platform will be based on an ultrahigh sensitivity magnetic nanoparticles detector and will look similar to a home pregnancy test with an electronic readout. As a bonus for healthcare providers and patients alike, it's expected to cost under $3 per test.
