High-performance detectors that are compatible with mainstream semiconductor device fabrication deliver high speed, ultra-sensitivity, and good timing resolution.

Recent advances in biomedical imaging include the enhancement of image contrast, 3D sectioning capability, and compatibility with specialized imaging modes such as fluorescence lifetime imaging (FLIM).^1–3 Compared with other imaging methods, FLIM offers the highest image contrast because it measures the lifetime of the fluorescence, rather than just its intensity or wavelength characteristics. The contrasting fluorescence lifetime attributes can then enable the observer to discriminate between regions, such as identifying healthy and diseased tissue for cancer detection. In conventional FLIM, a discrete single-photon detector, typically based on photomultiplier tube (PMT) technology, enables the acquisition of a single focal spot.⁴ This focal spot is then raster-scanned across the field of view to form an image. This approach, however, requires sequential scanning—pixel by pixel—and thus results in a slow image acquisition rate.

Aluminium builds up in the brain, eventually causing contamination which could cause the degenerative bran disease, researchers from Keele University previously found.

Researchers at the University of California, Riverside have developed a transparent “window to the brain” — a skull implant that is biocompatible, infection-resistant, and does not need to be repetitively replaced.

Part of the ongoing “Window to the Brain” project, a multi-institution, cross-disciplinary effort, the idea is to use transparent skull implants to provide laser diagnosis and treatment of a wide variety of brain pathologies, including brain cancers, traumatic brain injury, stroke, and neurodegenerative diseases, without requiring repeated craniotomies (a surgical operation in which a bone flap is temporarily removed from the skull to access the brain). Such operations are vulnerable to bacterial infections.

Ready for the strange? Here you go.

If you aren’t already purchasing organic or GMO-free rice, you should be. Rice that has been engineered with actual human genes is on its way to a supermarket near you. In Junction City, Kansas, this human gene-tainted rice is being grown on 3,200 acres by the biotechnology company Ventria Bioscience.

Ventria began cultivating this rather horrifying product in 2006 with human liver genes. What exactly was the purpose of this, you ask? Their intention was to harvest the artificial enzymes produced by the rice and use them in pharmaceuticals. Ventria has taken one of the most widely grown and consumed crops and turned it into the base for new prescription drugs — all with USDA approval, of course.

The constant battle between pathogens and their hosts has long been recognized as a key driver of evolution, but until now scientists have not had the tools to look at these patterns globally across species and genomes. In a new study, researchers apply big-data analysis to reveal the full extent of viruses’ impact on the evolution of humans and other mammals.

Their findings suggest an astonishing 30 percent of all protein adaptations since humans’ divergence with chimpanzees have been driven by viruses.

“When you have a pandemic or an epidemic at some point in evolution, the population that is targeted by the virus either adapts, or goes extinct. We knew that, but what really surprised us is the strength and clarity of the pattern we found,” said David Enard, Ph.D., a postdoctoral fellow at Stanford University and the study’s first author. “This is the first time that viruses have been shown to have such a strong impact on adaptation.”

The researchers say that the monochrome painting — a dime’s width across — is a proof-of-concept that the extremely precise technique can be used to build nanoscale chip-based devices like computer circuits, conductive carbon nanotubes, and for extremely efficient targeted drug delivery.

In order to reproduce the painting, the researchers used a technique first described by Rothemund and colleagues at IBM in 2009. The first step of the process involves folding DNA strands to create the desired shape, with short “staple strands” being used to literally staple the molecules. Then this pattern, which, at this stage, is floating in a saline solution, is poured into patches on a chip whose shapes match the DNA origami’s.

The folded DNA now acts as scaffolding onto which researchers then install fluorescent molecules inside microscopic light sources called photonic crystal cavities (PCC) — much like putting light bulbs into lamps.
