Crossing the Blood-Brain Barrier Using Lasers and Gold Nanoparticles

Delivering drugs to the brain remains a challenge due to the blood-brain barrier, a specialized endothelial layer that is highly selective in what it permits into the neural tissue beyond. At the University of Texas at Dallas, researchers have developed a technique that allows therapeutics to cross the blood-brain barrier, potentially allowing for new treatments […]

Laser-Assisted Bioprinting of Neurons

A team at Concordia University in Montreal have developed a technique called Laser-Induced Side Transfer (LIST) that allows for bioprinting of neurons. Low energy laser pulses are directed at a capillary containing a cell-laden bioink, resulting in microbubbles that eject a microjet of the ink onto the substrate below. The technique appears to be fairly […]

Chip Detects Antibiotics in Exhaled Breath

Researchers at the University of Freiburg in Germany have developed a chip that can measure antibiotic levels in breath, potentially paving the way for rapid point-of-care antibiotic testing. Attaining the correct levels of antibiotics in the body is crucial to effectively treating infections and avoiding drug side-effects or the development of antibiotic-resistant bacteria. The chip […]

China Wants to Be the World’s AI Superpower. Does It Have What It Takes?

China’s star has been steadily rising for decades. Besides slashing extreme poverty rates from 88 percent to under 2 percent in just 30 years, the country has become a global powerhouse in manufacturing and technology. Its pace of growth may slow due to an aging population, but China is nonetheless one of the world’s biggest […]

‘The Social Dilemma’ Will Freak You Out—But There’s More to the Story

Is social media ruining the world? Dramatic political polarization. Rising anxiety and depression. An uptick in teen suicide rates. Misinformation that spreads like wildfire. The common denominator of all these phenomena is that they’re fueled in part by our seemingly innocuous participation in digital social networking. But how can simple acts like sharing photos and […]
