Young nerve cells can rewind their developmental clocks

January 2, 2004

Scientists have identified a gene in the cerebral cortex that apparently controls the developmental clock of embryonic nerve cells, a finding that could open another door to tissue replacement therapy in the central nervous system.

The researchers found that they could rewind the clock in young cortical cells in mice by eliminating a gene called Foxg1. The finding could potentially form the basis of a new method to push… read more

You’ll buy more from web ads that know how you think

December 8, 2009

An “ad morphing” system that serves up banner ads that fit a website user’s personality type has been developed by MIT Sloan School of Management researchers.

It uses a program called the Bayesian Inference Engine running unobtrusively on a user’s computer to monitor the person’s click patterns to determine how they respond to different textual and visual cues. This is then used to categorize the user’s cognitive style and… read more

You, Too, Can Soon Be Like Tom Cruise in ‘Minority Report’

February 17, 2010

John Underkoffler, who helped create the gesture-based computer interface imagined in the film “Minority Report,” has brought that technology to real life in the new g-speak Spatial Operating Environment from Oblong Industries.

‘You, Robot’: personal robots for the masses

What would it be like if you could transfer your personal data, your consciousness, to a robot or a machine?”

That’s what almost every major technology organization seems to be asking, says Huffington Post blogger  Lucas Kavner.

Examples:

  • Terasem’s LifeNaut project allows you to create a mindfile for yourself, or anybody else close to you, using photos and online data and other “digital reflections” you

You, Robot

December 30, 2004

Roboticist Hans Moravec has founded Seegrid Corporation to develop vision-enabled robotic carts that can be loaded and then walked through various routes to teach them how to navigate on their own and move supplies around warehouses without human direction.

You won’t find consciousness in the brain

January 8, 2010

“We cannot conclude that when we see what seem to be neural correlates of consciousness that we are seeing consciousness itself”, says Ray Tallis, professor of geriatric medicine at the University of Manchester.

“While neural activity of a certain kind is a necessary condition for every manifestation of consciousness, from the lightest sensation to the most exquisitely constructed sense of self, it is neither a sufficient condition of it,… read more

You don’t ‘own’ your own genes

All human genes are patented many times over.

Court-proposed molecular points of distinction that allow claims on isolated DNA sequences. On the basis of two molecular changes (small circles) to a single phosphate and one hydroxyl group, the Federal Circuit court suggested that a new DNA fragment is patentable subject matter.

Humans no longer “own” their own genes.

The more than 40,000 patents on DNA molecules have allowed companies to essentially claim the entire human genome for profit, report two researchers. Their study, published March 25 in the journal Genome Medicine, raises an alarm about the loss of individual “genomic liberty.”

The research team examined two types of patented DNA sequences: long and short fragments. They discovered… read more

You Can’t Hide Your Lyin’ Brain

September 29, 2005

A scientist at the Medical University of South Carolina has found that magnetic resonance imaging machines also can serve as lie detectors, with more than 90 percent accuracy.

The MRI images show that more blood flows to parts of the brain associated with anxiety and impulse control when people lie. More blood also flows to the part of the brain handling multitasking because it is hard for people to… read more

Yogi alert: a new concept for a bed of needles

No more removal "ouch"
April 18, 2013

The Karp lab invented a bio-inspired flexible microneedle adhesive patch (2 x 2 cm) that can stick to soft tissues (credit: Karp lab)

Researchers at Brigham and Women’s Hospital (BWH) have invented a microneedle adhesive more than 3x stronger than surgical staples for skin graft fixation, inspired by Pomphorhynchus laevis, a spiny-headed worm that lives in the intestines of its hosts, in this case fish.

The worm securely attaches to the host’s intestinal wall by penetrating, and then plumping up its elongated, cactus-like head into the intestinal tissue.… read more

Yoga as a potential therapy for cardiovascular disease and metabolic syndrome

December 30, 2014

A systematic review of 37 randomized controlled trials showed promising evidence for the ability of yoga to improve cardiovascular and metabolic health, but found no significant difference in the effectiveness of yoga versus aerobic exercise.

Yoga showed significant improvement in body mass index, systolic blood pressure, low-density lipoprotein cholesterol, and high-density lipoprotein cholesterol; and significant changes in body weight, diastolic blood pressure, total cholesterol, triglycerides, and heart rate.… read more

YeZ concept car sucks in C02, exhales oxygen

May 24, 2010

(Shanghai Automotive Industry Corporation)

Shanghai Automotive Industry Corporation’s YeZ, a concept car, behaves like a plant, converting carbon dioxide from the air via photosynthesis into oxygen that is sent back into the atmosphere.

YeZ uses photoelectric conversion from solar panels on the roof, wind power conversion via small wind turbines in the wheels, and carbon dioxide absorption and conversion through the bodywork.

Yes, congenital blind can learn to link vision and touch

April 12, 2011

Sense of Touch

Researchers at MIT have shown that the brain does not have an innate ability to connect different types of sensory input, but can quickly learn to do so.

The researchers tested five children with treatable forms of blindness to answer the question: could they visually distinguish between objects that they could previously only identify by touch? This question was first raised by scientist William Molyneux… read more

Yeast-powered fuel cell feeds on human blood

April 2, 2009

Yeast cells feeding on the glucose in human blood might one day power implants such as pacemakers, eliminating the need for regular operations to replace batteries.

University of British Columbia scientists have developed tiny microbial fuel cells by encapsulating yeast cells in a flexible capsule.

Yeast-Based Oral Diabetes Treatment Discovered

January 3, 2008

University of Haifa researchers have discovered a yeast-derived substance called Glucose Tolerance Factor (GTF) that acts similarly to insulin and may become an oral treatment for diabetes and its complications.

In the studies–done on cell cultures and on diabetic rats–GTF inhibited oxidation processes that could cause atherosclerosis and further complications like strokes and heart attacks. When GTF was given at the early stage of the disease, it could prevent… read more

Yeast protein wires supercomputers

April 2, 2003

Investigators are experimenting with biological materials that can arrange themselves into strings spontaneously, using genetically engineered yeast amyloids or prions. These strands would be stable and would serve as the backbone for metal to attach onto, creating wires for self-assembling electronic circuits.
