Gold nanoparticle sensor produces simple urine test for cancer

Posted by in categories: biotech/medical, nanotechnology

Imperial College London biomedical materials scientist Molly Stevens teamed up with Massachusetts Institute of Technology biomedical engineer Sangeeta Bhatia to develop the approach, which they think has the potential to help patients in low-resource and rural areas, where available medical technology may be limited. Stevens specializes in low-cost catalyst-based diagnostics and Bhatia works on creating nanosensors that respond to enzymatic activity. The two combined their expertise to create nanoparticle-protein complexes that, once injected, can reveal the presence of disease-related enzymes through a simple urine test.

2019 Developer Circles from Facebook Community Challenge

Posted by in categories: augmented reality, business, entertainment

Facebook’s Developer Circles are local communities designed to help developers learn and grow. For the 2019 Developer Circles Community Challenge, you are invited to build software applications that use at least one of three featured technologies: React360, Spark AR, and/or HTML5 Games. Your software must also fit into one of three categories: Gaming and Entertainment, Productivity and Utility, or Social Good.


Build software using React360, Spark AR, or HTML5 Games to give people the power to connect with friends and family, find communities and grow businesses.

Searching for the 80,000 Disappeared in Colombia’s Brutal Civil War

Posted by in category: government

SAN JOSE DEL GUAVIARE, COLOMBIA — Cerafín Méndez was out drinking one night when a fight broke out with his neighbor. The next day, three FARC soldiers came for him, bound his hands, and led him away.

That was the last time his family would see him alive.

Making and controlling crystals of light

Posted by in category: transportation

Optical microresonators convert laser light into ultrashort pulses travelling around the resonator’s circumference. These pulses, called “dissipative Kerr solitons,” can propagate in the microresonator maintaining their shape.

When solitons exit the , the output takes the form of a train—a series of repeating pulses with fixed intervals. In this case, the repetition rate of the pulses is determined by the microresonator size. Smaller sizes enable pulse trains with high repetition rates, reaching hundreds of gigahertz in frequency. These can be used to boost the performance of optical communication links or become a core technology for ultrafast LiDAR with sub-micron precision.

Exciting though it is, this technology suffers from what scientists call “light-bending losses”—loss of light caused by structural bends in its path. A well-known problem in , light-bending loss also means that the size of microresonators cannot drop below a few tens of microns. This therefore limits the maximum repetition rates we can achieve for pulses.

‘Exceptionally rare’ lightning storm stuns Puget Sound

Posted by in category: climatology

SEATTLE, Wash. — There were 2,275 bolts of lightning in Saturday’s lightning storm that shocked Puget Sound, according to the National Weather Service on Sunday.

“To have this much lightning in the lowlands is exceptionally rare,” said Reid Wolcott, Warning Coordination Meteorologist for the National Weather Service.

A New Laser Technology Can See Inside Our Bodies Like Never Before

Posted by in categories: biotech/medical, nanotechnology

While X-rays can produce harmful radiation, a new technique using laser-induced sound waves provides highly detailed images of the structures in our bodies.

Photoacoustic imaging is an emerging imaging technique that shoots micro-pulses of laser light at a specimen or body part, which selectively heats up parts of the tissue causing them to expand, and generate waves of pressure – a.k.a. sound waves.
