Bio-engineers are working on the development of biological computers with the aim of designing small circuits made from biological material that can be integrated into cells to change their functions. In the future, such developments could enable cancer cells to be reprogrammed, thereby preventing them from dividing at an uncontrollable rate. Stem cells could likewise be reprogrammed into differentiated organ cells.

Scientists at the Universities of Bonn and Cardiff see good times approaching for astrophysicists after hatching a new observational strategy to distill detailed information from galaxies at the edge of the Universe. Using two world-class supercomputers, the researchers were able to demonstrate the effectiveness of their approach by simulating the formation of a massive galaxy at the dawn of cosmic time.
This 50X photo shows cross-cut through an assembly of two dark-brown fiber-reinforced composite pieces, which are bonded together with gray adhesive and back-filled with a blue mass of composite material. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using reflected light and darkfield.
New software algorithms have been shown to significantly reduce the time and material needed to produce objects with 3-D printers. The algorithms have been created to address the problem. Researchers from Purdue University have demonstrated one approach that has been shown to reduce printing time by up to 30 percent and the quantity of support material by as much as 65 percent.
Russian scientists have developed a theoretical model of quantum memory for light, adapting the concept of a hologram to a quantum system. The authors demonstrate for the first time that it is theoretically possible to retrieve, on demand, a given portion of the stored quantized light signal of a holographic image — set in a given direction in a given position in time sequence.
Complex biochemical signals that coordinate fast and slow changes in neuronal networks keep the brain in balance during learning, according to scientists who report on a six-year quest by a collaborative team from the three institutions to solve a decades-old question and open the door to a more general understanding of how the brain learns and consolidates new experiences on dramatically different timescales.
This 200X photo shows the freshwater flea Daphnia magna. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using differential interference contrast and image stacking.
The supply chain is ground zero for several recent cyber breaches. Hackers, for example, prey on vendors that have remote access to a larger company's global IT systems, software and networks. In the 2013 Target breach, the attacker infiltrated a vulnerable link: a refrigeration system supplier connected to the retailer's IT system. A counter-measure, via a user-ready online portal, has been developed at the Supply Chain Management Center.
High-speed bi-directional wireless technology that uses light to send information securely offers faster, safer transfer of data than conventional wi-fi. Because it does not rely on the radio spectrum, it provides 10,000 times more bandwidth. Light-enabled wi-fi, or Li-Fi, was first developed by Professor Harald Haas, Chair of Mobile Communication with the University of Edinburgh. Haas is co-founder of the spin-out company pureLiFi.
Earth is on pace to tie or even break the mark for the hottest year on record, federal meteorologists say. That's because global heat records have kept falling in 2014, with September the latest example. The National Oceanic and Atmospheric Administration announced October 20, 2014, that last month the globe averaged 60.3 degrees Fahrenheit (15.72 degrees Celsius). That was the hottest September in 135 years of record keeping.
This 10X photo shows the surface details of a one euro coin. It received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope, and was taken using confocal reflection microscopy, Z-stacking and maximum intensity projection.
The drug creation process often misses many side effects that kill at least 100,000 patients a year. LLNL researchers have discovered a high-tech method of using supercomputers to identify proteins that cause medications to have certain adverse drug reactions, using high-performance computers to process proteins and drug compounds in an algorithm that produces reliable data outside of a laboratory setting for drug discovery.
Through a computational algorithm, researchers have developed a neural network that allows a small robot to detect different patterns, such as images, fingerprints, handwriting, faces, bodies, voice frequencies and DNA sequences. Nancy Guadalupe Arana Daniel focused on the recognition of human silhouettes in disaster situations.
What do the DNA in Australian seaweed, Amazon River water, tropical plants, and forest soil all have in common? Lots, say scientists. And understanding the genetic similarities of disparate life forms could enable researchers to produce compounds for new medicines, eco-friendly materials, more resilient crops, and cleaner air, water and energy.
The purpose of this series is to discuss the impact of GMP (Good Manufacturing Practice) regulations on cloud computing and to debate some of the regulatory issues facing an organization contemplating this approach. In this part, we look at the applicable regulations.
A profound new discovery reveals how the intimate act of sexual intercourse first evolved in our deep distant ancestors. In one of the biggest discoveries in the evolutionary history of sexual reproduction, Flinders University Professor John Long has found that internal fertilization and copulation was invented by ancient armored fishes, called placoderms, about 385 million years ago in Scotland.
