Raelians will not provide proof of cloning

January 21, 2003

Raelian follower Marc LeTourneau said in a speech that none of the people involved with the (alleged) recent cloning want their identities to become known or will permit testing.

He also said ill people would be allowed to shift their DNA into healthy bodies, thereby allowing the essence of a person to live much longer.

Nanowires That Behave Like Cells

August 11, 2009

Researchers at the Lawrence Livermore National Laboratory have sealed silicon-nanowire transistors in a membrane similar to those that surround biological cells.

These hybrid devices, which operate similarly to nerve cells, might be used to make better interfaces for prosthetic limbs and cochlear implants. They might also work well as biosensors for medical diagnostics.

Cyber Goggles for Human Tagging

Researchers at the University of Tokyo have developed a smart video goggle system that records everything the wearer looks at, recognizes and assigns names to objects that appear in the video, and creates an easily searchable database of the recorded footage.

It can function as a memory aid for the elderly, or search through hours of video footage to find particular images.

Is There a Link Between Stress and Cancer?

November 29, 2005

A tenuous connection has emerged between stress, the immune system, and cancer, with a surprising new insight that is changing the direction of research: it now appears that cancer cells make proteins that actually tell the immune system to let them alone and even to help them grow.

One immediate consequence of this line of thinking is a new idea for treatment: scientists could seal off the cancer cells’… read more

Nanodevice Breaks 1-GHz Barrier

February 10, 2003

Nanoscientists have achieved a milestone in their burgeoning field by creating a device that vibrates a billion times per second, or at one gigahertz (1 GHz). The accomplishment further increases the likelihood that tiny mechanical devices working at the quantum level can someday supplement electronic devices for new products.

A Lunar Nuclear Reactor

August 18, 2009

A “safe, reliable, and efficient” nuclear fission reactor that could power a human outpost on the moon or Mars by 2020 has been tested by researchers at NASA and the Department of Energy.

Taiwanese researchers reported today (July 30) in the journal Nanotechnology that they have developed a simple electrochemical approach that allows for defects to intentionally be created in graphene, altering its electrical and mechanical properties and making the material more useful for electronic devices and drug delivery, for example.

Current graphene synthesis techniques, such as chemical vapor deposition and reduction of graphene oxide, can only produce graphene with a narrow… read more

Revenge of the Experts

March 10, 2008

The individual user has been king on the Internet, but the pendulum seems to be swinging back toward edited information vetted by professionals.

Cases in point: Google’s Knol, a Wikipedia-like Web site produced by “authoritative” sources; BigThink.com, a “YouTube for ideas,” with polished video interviews with public intellectuals; and Mahalo, which replaces Google’s popularity-based page rankings with results that the start-up says are based on quality and vetted by… read more

How the Neuron Sprouts Its Branches

December 11, 2005

Howard Hughes Medical Institute researchers have found that structures called “Golgi outposts” play a central role as distribution points for proteins that form the building blocks of growing dendrites.

“This finding is important because a fundamental problem that neurons must solve is how to sort appropriate cargo molecules in the right amounts down different dendritic branches,” said investigator Micheal Ehlers. “We’ve found that these dendritic Golgi outposts are located… read more

Dr. Ben Goertzel on artificial general intelligence, transhumanism and open source

June 14, 2011

At the recent 2011 Transhumanism Meets Design Conference in New York City, Dr. Ben Goertzel addressed two key questions regarding artificial general intelligence (AGI): How can we design a world (virtual or physical) so that it supports ongoing learning and growth and ethical behavior? How can we design a mind so that it takes advantage of the affordances its world offers?

In an PhysOrg.com interview, Goertzel expands on… read more

The Robot Ate My Homework

February 20, 2003

Robots are helping kids who are hospitalized for long periods by trauma or chronic illness keep up with school.

One goes to school in the absent child’s place. Another in the hospital transmits an image of the child’s face to the classroom. The child can direct the school robot to raise its hand to ask a question or swivel its head to follow the teacher.

New genetic mechanism that controls body’s fat-building process found

August 27, 2009

A University of Central Florida research team has identified a gene called MCPIP (Monocyte Chemotactic Protein-1 Induced Protein) that controls the development of fat cells.

MCPIP could be an ideal target for drugs that can shut down its function to prevent obesity and the major inflammatory diseases resulting it, including diabetes and cardiovascular diseases.

Nanovalves for Drug Delivery

March 13, 2008

A new nanovalve that opens in response to pH changes could serve as the basis of a targeted drug delivery system.

By filling a tiny, porous silica sphere with a drug and then plugging the pores with the valves, Northwestern University and UCLA researchers can use pH changes to control the drug’s release.

Singularity Is Near is #13 on NY Times most-blogged-about list

December 23, 2005

Ray Kurzweil’s The Singularity Is Near: When Humans Transcend Biology has been named #13 on the New York Times list of “most blogged about books of 2005.”
