Green tea extract blocks formation of amyloid plaques in Alzheimer’s disease

March 8, 2013

green_tea_alzheimer

Researchers at the University of Michigan have found a new potential benefit of a molecule in green tea: preventing the misfolding of specific proteins in the brain.

U-M Life Sciences Institute faculty member Mi Hee Lim and an interdisciplinary team of researchers used green tea extract to control the generation of metal-associated amyloid-β aggregates associated with Alzheimer’s disease in the lab.

The specific molecule… read more

“The rise of the drone is not a case of technology run amok. It is the result of human decision: of political calculation and, too often, strategic evasion,” says author Fred Kaplan in MIT Technology Review.

“Judging from its expanded use over the past five years, the drone’s chief danger is that it makes war too easy — so easy that commanders, including the commander-in-chief, can fool themselves… read more

How science can build a better you

November 4, 2012

How far would you go to modify yourself using the latest medical technology?

In a New York Times article Saturday, author and broadcaster David Ewing Duncan offers a partial checklist of cutting-edge medical-technology therapies now under way or in an experimental phase that might lead to future enhancements, including:

Present:

  • supermemory or attention pill
  • cochlear implant to improve hearing
  • brain-boosting neuro-feedback and

In a landmark paper, published this week in PNAS (forthcoming), the EPFL’s Blue Brain Project (BBP) has identified key principles that determine synapse-scale connectivity by virtually reconstructing (in supercomputer) a cortical microcircuit and comparing it to a mammalian sample.

These principles now make it possible to predict the locations of synapses in the neocortex, the researchers say.

“This is a major breakthrough,… read more

NIH explains Brain Research through Advancing Innovative Neurotechnologies (BRAIN) initiative

April 5, 2013

Billionaire investor Peter Thiel’s philanthropic foundation has announced a six-figure grant for bioprinted meat, part of an ambitious plan to bring to the world’s dinner tables a set of technologies originally developed for creating medical-grade tissues, CNET reports.

The recipient of the Thiel Foundation’s grant, a Columbia, Mo.-based startup named Modern Meadow, is pitching bioprinted meat as a more environmentally-friendly way to satisfy… read more

Representative Steve Israel, Democrat of New York wants to extend an existing law, set to expire this year, that makes weapons that are undetectable by security scanners — like a printed all-plastic gun — illegal, The New York Times reports.

But there are also major technical obstacles to creating an entire gun on a 3-D printer, not the least of which is that a plastic gun would… read more

Research debunks the ‘IQ myth’

December 21, 2012

After conducting the largest online intelligence study on record, with more than 100,000 participants, a Canadian Western University-led research team has concluded that the notion of measuring one’s intelligence quotient or IQ by a singular, standardized test is highly misleading.

Utilizing an online study open to anyone, anywhere in the world, the researchers asked respondents to complete 12 cognitive tests tapping memory, reasoning, attention and… read more

How the Bolshoi simulation evolves the universe all over again
October 3, 2012

cosmic_web

Most of the ordinary matter in the universe — the stuff that makes up all the atoms, stars, and galaxies astronomers can see — is invisible, either sprinkled throughout intergalactic space in tenuous forms that emit and absorb little light or else swaddled inside galaxies in murky clouds of dust and gas, Joel R. Primack writes in IEEE Spectrum.

When astronomers look out into the night… read more

A 3D-printed Moon base baked from lunar dust

sinterhab-moon-base-4

Space architects have unveiled a concept for a 3D-printed Moon base called SinterHab near the lunar south pole. Modules would be constructed from lunar dust by microwave sintering and contour crafting, built by a large NASA spider robot.

Unlike an earlier, more bulky concept using a mobile printing array of nozzles on a 6 meter frame to spray a binding solution (glue) onto… read more

Non-invasive brain-to-brain interface: links between two brains

Direct communication between the brains of human and rat .... or between humans
April 8, 2013

brainstorm

We reported last month how Duke University researchers remotely linked the brains of two rats. Now researchers from the U.S and South Korea have have taken it a step further: a non-invasive functional link … and between the brains of different species (human and rat) — a brain-to-brain interface (BBI).

The researchers — at Brigham and Women’s Hospital and Harvard Medical School. — set up a system intended… read more

Amazingly realistic digital screen characters are finally here

Meet Zoe: a digital talking head. She can express a range of human emotions on demand with “unprecedented realism” and could herald a new era of human-computer interaction, according to researchers at Toshiba’s Cambridge Research Lab and the University of Cambridge’s Department of Engineering, who created her.

Zoe, or her offspring, could be used as a visible version of Siri, as… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

NewsImage-GeneRepair

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more
