Anti-inflammatory luteolin concentrated in nanocapsules in the blood inhibits lung-cancer growth

January 9, 2014

nano-luteolin

Researchers at the Winship Cancer Institute of Emory University have discovered a more effective drug delivery system using nanoparticles that could one day significantly affect cancer prevention.

The study, published in Cancer Prevention Research, involved the use of microscopic amounts of the naturally occurring antioxidant, luteolin, that were encapsulated in a water-soluble polymer. When injected into mice, the nano-luteolin inhibited growth of lung cancer and… read more

Creating living brain cells from deceased Alzheimer’s patients’ biobanked brain tissue

New stem cell lines will allow researchers to “turn back the clock” and observe how Alzheimer’s develops in the brain, potentially revealing the onset of the disease at a cellular level

Biobank IPS cells shown to retain pluripotency

Scientists at The New York Stem Cell Foundation (NYSCF) Research Institute, working in collaboration with scientists from Columbia University Medical Center (CUMC), have for the first time generated induced pluripotent stem (iPS) cells lines from non-cryoprotected brain tissue of patients with Alzheimer’s disease.

These new stem cell lines will allow researchers to “turn back the clock” and observe how Alzheimer’s develops in the brain, potentially revealing the… read more

FLIR Systems launched at CES the FLIR ONE, the first consumer-oriented thermal imaging system for a smartphone.

Acting as a case for the Apple iPhone 5 or 5s smartphone, the FLIR ONE displays a live thermal image on the phone’s screen, letting you see in complete darkness.

FLIR ONE senses heat rather than light, using the same professional thermal imaging technology that FLIR uses in its… read more

Cloning quantum information from the past

It is theoretically possible for time travelers to copy quantum data from the past, according to three scientists in a recent paper in Physical Review Letters.

It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the Grandfather paradox*.  He solved the paradox originally using a slight change to quantum theory,… read more

How to find time travelers

January 8, 2014

Is Jay-Z a time traveler? --- desusnice (Buzz Feed) (credit: The Schomburg Center for Research in Black Culture/New York Public Library)

If there were time travelers among us, how would you find them?

That question occurred to astrophysicist Robert Nemiroff, a professor at Michigan Technological University. So he and his team developed a search strategy based on what they call “prescient knowledge.”

If they could find a mention of something or someone on the Internet before people should have known about it, that could indicate that whoever wrote it… read more

Piggy-backing proteins ride white blood cells to destroy metastasizing cancer

“Unnatural killer cells" zap circulating tumor cells in the bloodstream
January 8, 2014

nanoscale_liposomes_trail

Cornell biomedical engineers have discovered a new way to destroy metastasizing cancer cells traveling through the bloodstream by hitching cancer-killing proteins along for a ride on life-saving white blood cells.

“These circulating cancer cells are doomed,” said Michael King, Cornell professor of biomedical engineering and the study’s senior author.

“About 90 percent of cancer deaths are related to metastases, but now we’ve found a way to… read more

RAMBO: a small but powerful magnet

Rice University system allows high-magnetic-field experiments on a tabletop
January 8, 2014

0106_RAMBO-1-web

RAMBO (Rice Advanced Magnet with Broadband Optics) — a tabletop magnetic pulse generator that does the work of a room-sized machine — has been developed by Rice University scientists.

The device will allow researchers who visit the university to run spectroscopy-based experiments on materials in pulsed magnetic fields of up to 30 tesla. (A typical high-resolution magnetic resonance imaging system used in hospitals… read more

Intel is introducing at CES several new products and projects focused on wearables:

  • Jarvis, a headset that can automatically integrate with a personal assistant app like Siri on a phone without touching it.
  • A smartwatch with “geo-fencing” to monitor the person who’s wearing it. For example: in case of an emergency and a person steps out of the geo-fence, the watch can send out an alert.

An easy, low-cost way to get into 3D printing

January 7, 2014

MakerBot Mini

If you’ve been thinking about getting into 3D printing, the compact MakerBot Replicator Mini 3D printer, just introduced at CES, could make it easy and affordable at $1,375 (available spring 2014).

It’s limited to printing objects around 4 x 4 x 4 inches, but the company claims it’s easy to use, with no 3D skills needed. You can download models from the free MakerBot Printshop and Thingverse,… read more

Growing human organs inside pigs in Japan

Meiji University professor Hiroshi Nagashima is creating chimeric pigs, which carry genetic material from two different species, BBC News reports. It starts off by making what Nagashima calls “a-pancreatic” embryos. Inside the white pig embryo, the gene that carries the instructions for developing the animal’s pancreas has been “switched off.”

The Japanese team then introduces stem cells from a black pig into the embryo. What they have… read more

Open collaboration leading to novel organizations

Open collaboration — which has brought the world Bitcoin, TEDx and Wikipedia — is likely to lead to new organizations that are not quite non-profits and not quite corporations, according to a paper by Sheen S. Levine of Columbia University and Michael J. Prietula of Emory University published in the journal Organization Science.

The authors define open collaboration as “any system of innovation or production that relies on goal-oriented yet… read more

Making silicon devices responsive to infrared light

January 6, 2014

silicon_infrared

A new system developed by researchers at five institutions, including MIT, could eliminate many limitations in methods to develop detectors that are responsive to a broad range of infrared light. Such detectors could form sensitive imaging arrays for security systems, for example.

The new system works at room temperature and provides a broad infrared response, says associate professor of mechanical engineering Tonio Buonassisi.

Compound-forming vs non-compound-forming systems.  (Adapted from G. Hart et al./Phys. Rev. X)

In the search for cheaper materials that mimic their purer, more expensive counterparts, researchers are abandoning hunches and intuition for theoretical models and pure computing power.

In a new study, researchers from Duke University’s Pratt School of Engineering used computational methods to identify dozens of platinum-group alloys that were previously unknown to science but could prove beneficial in a wide range of applications.

Imagined autonomous vehicle

Self-driving vehicles offer the promise of significant benefits to society, but raise several policy challenges, including the need to update insurance liability regulations and privacy concerns such as who will control the data generated by this technology, according to a new RAND Corporation study.

“Our research finds that the social benefits of autonomous vehicles — including decreased crashes, increased mobility and increases… read more

Tel Aviv University researchers have developed a computer algorithm that predicts which genes can be “turned off” to create the same anti-aging effect as calorie restriction*. The findings, reported in Nature Communications, could lead to the development of new drugs to treat aging.

“Most algorithms try to find drug targets that kill cells to treat cancer or bacterial infections,” says Keren Yizhak, a doctoral student in Prof.… read more
