Firefly gene makes mice glow to track cancer and aging in real time

January 21, 2013

University of North Carolina Lineberger Comprehensive Cancer Center researchers have developed a strain of mice that turns on a gene from fireflies to provide a visual indication of aging and tumor growth in mice. The mice light up whenever another mouse gene, p16INK4a (p16) is is activated (in cells undergoing senescence, the p16 gene is switched on).

The researchers followed p16 activation by simply tracking the… read more

A Queensland Institute of Medical Research (QIMR) Associate Professor David Harrich has developed a way to use HIV to beat HIV in the laboratory.

He has determined how to modify a protein in the virus, creating the the “Nullbasic” protein, which provides strong, lasting protection from infection by stopping the virus from replicating in a lab environment. Animal trials are due to start this year.

“If this… read more

Highest-efficiency flexible thin-film solar cells

January 21, 2013

Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin-film solar cells on flexible polymer foils with a new record efficiency of 20.4%.

The cells are based on CIGS  (copper indium gallium (di)selenide) semiconducting material.

Thin-film, lightweight, flexible high-performance solar modules are attractive for solar farms, roofs and facades of buildings, automobiles, and portable electronics and can be produced using… read more

Kim Suozzi, diagnosed at age 21 with brain cancer while studying neuroscience at college, passed away Thursday, January 17, 2013 at age 23.

The Society for Venturism, a cryonics advocacy and support group, started a charity fund for her cryonic suspension in August of 2012 and through an overwhelming amount of support from the extreme life extension community, enough funds were raised for her to be cryopreserved with Alcor.… read more

Micron readies hybrid memory cube for debut

January 18, 2013

hybrid_memory_cube

The next-generation memory-maker Micron Technology‘s Hybrid Memory Cube (HMC) technology is a multi-chip module (MCM) that aims to address one of the biggest challenges in high performance computing: scaling the memory wall, HPC Wire reports.

Memory architectures haven’t kept pace with the bandwidth requirements of multicore processors. As microprocessor speeds out-accelerated DRAM memory speeds, a bottleneck developed that is referred to as the… read more

Mathematicians aim to take publishers out of publishing

Episciences Project to launch series of community-run, open-access journals
January 18, 2013

arxiv

Mathematicians plan to launch a series of free open-access journals that will host their peer-reviewed articles on the preprint server arXiv, Nature News reports. The project was publicly revealed yesterday in a blog post by Tim Gowers, a Fields Medal winner and mathematician at the University of Cambridge, UK.

The initiative, called the Episciences Project, hopes to show that researchers can organize the… read more

A global group of scientists and engineers, including from the University of Southampton, has published in a special issue journal of the Royal Society in support of tidal power, which has the potential to provide more than 20 per cent of the UK’s electricity demand, they calculate.

While the predictable nature of tides makes them an ideal renewable energy source, more so than wind, the… read more

Is the ‘quantum singularity’ near?

January 18, 2013

quantum_aaronson

Four research groups have announced progress on a quantum-computing proposal made two years ago by MIT researchers.

In early 2011, two theoretical computer scientists at MIT proposed an optical experiment that would harness the weird laws of quantum mechanics to perform a computation impossible on conventional computers.

Commenting at the time, Terry Rudolph, a quantum-computing researcher at Imperial College London said that the experiment… read more

New surfaces repel most known liquids

January 18, 2013

Scientists have developed new “superomniphobic” surfaces that will lead to stain-proof, spill-proof clothing, protective garments, and other products that shrug off virtually every liquid — from blood and ketchup to concentrated acids.

Anish Tuteja and colleagues point out that scientists have previously reported “omniphobic” surfaces, the term meaning that such surfaces can cause a range of different liquids to bead up and not spread on them. But… read more

With the rapidly expanding use of brain and spinal cord stimulation therapy (neuromodulation), “remote presence” (telepresence) technologies may help to meet the demand for experts to perform stimulator programming, reports a study published in Neurosurgery.

The preliminary study by Dr. Ivar Mendez of Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, Canada, supports the feasibility and safety of using a telepresence robot (“RP-7″) to increase… read more

Michigan State University (MSU) scientists have redesigned a “robotic fish,” giving it the ability to glide long distances, using little to no energy, while measuring water temperature and quality and other data that can aid in testing and cleaning lakes and rivers.

According to research team leader Xiaobo Tan, MSU associate professor of electrical and computer engineering, while gliding  uses less energy, it’s slower and less… read more

Quantum dots go on display

January 17, 2013

QD-Vision-Color.graph

Researchers working with nanoscale fluorescent particles called quantum dots have long predicted groundbreaking achievements, such as ultra-efficient light-emitting diodes (LEDs) and solar cells, but the technology has found mainly niche applications.

That could change with the announcement last week that QD Vision would supply Sony Corporation of Tokyo with quantum dots for flat-screen televisions that will transmit more richly colored images than other TVs on… read more

According to software expert Tim Huckaby, we’re on the verge of a science-fiction-like future where doctors manipulate molecules in three-dimensional (3-D) space, augmented music players tune into your thoughts, and retailers deliver coupons in real time based on the focus of your gaze across store shelves, Smart Planet reports.

His predictions for what’s possible within the next 10 years include a functioning “holodeck” (as in Star Trek)… read more

The next generation of PrimeSense‘s 3D sensor (used inside the Microsoft Kinect), called Capri, will revolutionize vision for very cheap and very expensive robots, IEEE Spectrum reports.

Capri is also small enough that it’ll be able to fit into tablets (and eventually smartphones).

The first engineering samples of Capri are expected to ship in 2-3 months, with consumer kits… read more
