Qualcomm is Building a Digital Human Brain

February 14, 2012 | by

During the President’s Lecture Series at San Diego State University two weeks ago, Qualcomm CEO Paul Jacobs said that the company is building a digital human brain. Stating that the brain isn’t programmed but rather taught, Jacobs emphasized that the company’s work was meant to help humanity through the “digital sixth sense” — the merging of the cyber and real worlds.

He described the process of discovery this way:

The team actually started out by building a retina and they came to me and said: ‘Look, it responds to these optical illusions the same way a human does.’ They put another layer of cells behind that [and] it started to find features. They put another layer, it started to find corners or oriented lines or something. Another layer, it started to find patterns.

Jacobs is talking about Brain Corporation, a small research company that is developing novel algorithms based on the functionality of the nervous system, with applications in visual perception, motor control, and autonomous navigation. The intention is to equip consumer devices, such as mobile phones or household robots, with artificial nervous systems. Qualcomm funds Brain Corporation research and hosts the company on its campus in San Diego, California.

Scientists at Brain Corporation are re-creating in the computer the shapes of every one of the billions of nerve cells that make up our brains, the component parts of intricate neural circuits that allow us to move, see and hear, to feel and to think. With this new tool, researchers are beginning to decipher the secrets of the brain’s architecture, which may one day enable us to build smart technologies that surpass the capabilities of anything we have today.

Portable “Life and Activity Monitor” Records Vital Signs

February 9, 2012 | by

Scientific research and studies that will advance the understanding of medicine often require patients to undergo vital statistic monitoring, including measurement and recording of heart rate, activity level, and respirations. However, monitoring such vital statistics has historically required that study participants agree to frequent office visits, or else wear large and cumbersome monitoring devices.

Researchers at Oregon State University and the University of California at San Diego have designed a miniature vital statistics monitor that is not only small — it’s about two inches wide — and inexpensive to make, but is also capable of monitoring vitals from inside a pocket.

Life and activity monitor

From Oregon State University’s press release:

“When this technology becomes more miniaturized and so low-cost that it could almost be disposable, it will see more widespread adoption,” said Patrick Chiang, an assistant professor of computer engineering at Oregon State University. “It’s already been used in one clinical research study on the effects of micronutrients on aging, and monitoring of this type should have an important future role in medicine.”

Vital statistics monitors like this one may make large-scale medical studies easier on participants and less expensive for labs to run, speeding the pace of health discovery and innovation.

Embryonic Stem Cells Improve Vision of Blind Patients

February 7, 2012 | by

Researchers at UCLA’s Jules Stein Eye Institute and colleagues have successfully used specialized retinal cells derived from human embryonic stem cells to improve the vision of two legally blind patients.

The trial was led by Dr. Steven Schwartz, opthalmologist and chief of the retina division at the Institute. Although the results are extremely promising, only two patients were treated. The trial will have to be preformed successfully many more times before the procedure can be accepted as an option for care.

Nevertheless, the preliminary findings represent a milestone in the therapeutic use of stem cells and may pave the way for a new therapy to treat eye diseases. The research was recently published online in the journal The Lancet.

Drug Companies Collaborate to Fight Neglected Tropical Diseases

February 2, 2012 | by

A global initiative to fight neglected tropical diseases launched in London this week. The so-called London Declaration calls for the eradication of 10 neglected tropical diseases by 2020. Experts are calling it the largest coordinated effort ever undertaken to combat diseases that affect 1.4 billion people in the world’s poorest countries.

F1000 Launches Open Access Publishing for Biology and Medicine

February 1, 2012 | by

This week, the Faculty of 1000 (F1000), announced F1000 Research, a new fully Open Access publishing program across biology and medicine that will launch later this year [1]. F1000 Research is intended to address the major issues afflicting scientific publishing today: timely dissemination of research, peer review, and sharing of data.
