Nanoparticles Destroy Cancer

Remotely Activated Nanoparticles Destroy Cancer.

The first in a new generation of nanotechnology-based cancer treatments will likely begin clinical trials in 2007, and if the promise of animal trials carries through to human trials, these treatments will transform cancer therapy. By replacing surgery and conventional chemotherapy with noninvasive treatments targeted at cancerous tumors, this nanotech approach could reduce or eliminate side effects by avoiding damage to healthy tissue. It could also make it possible to destroy tumors that are inoperable or won’t respond to current treatment.

One of these new approaches places gold-coated nanoparticles, called nanoshells, inside tumors and then heats them with infrared light until the cancer cells die. Because the nanoparticles also scatter light, they could be used to image tumors as well. Mauro Ferrari, a leader in the field of nanomedicine and professor of bioengineering at the University of Texas Health Science Center, says this is “very exciting” technology.

“With chemotherapy,” Ferrari says, “we carpet bomb the patient, hoping to hit the lesions, the little foci of disease. To be able to shine the light only where you want this thing to heat up is a great advantage.”

Anti Aging Molecule Discovered

Anti-Aging Molecule Discovered

A team of South Korean scientists on Sunday claimed to have created a “cellular fountain of youth,’’ or a small molecule, which enables human cells to avoid aging and dying.

The team, headed by Prof. Kim Tae-kook at the Korea Advanced Institute of Science and Technology, argued the newly-synthesized molecule, named CGK733, can even make cells younger.

The findings were featured by the Britain-based Nature Chemical Biology online early today and will be printed as a cover story in the journal’s offline edition early next month.

“All cells face an inevitable death as they age. On this path, cells became lethargic and in the end stop dividing but we witnessed that CGK733 can block the process,’’ Kim said.

“We also found the synthetic compound can reverse aging, by revitalizing already-lethargic cells. Theoretically, this can give youth to the elderly via rejuvenating cells,’’ the 41-year-old said.

Kim expected that the CGK733-empowered drugs that keep cells youthful far beyond their normal life span would be commercialized in less than 10 years.

Reading things like this sometimes gives me the impression that significant life extension is closer than you’d think. I’ll bet humanity is going to see a great improvement in public health in the next decade.

And thanks to the recent change of year, the next decade is now only 3 years away. ;)

Mad Cow Breakthrough

Scientists Announce Mad Cow Breakthrough

Scientists said yesterday that they have used genetic engineering techniques to produce the first cattle that may be biologically incapable of getting mad cow disease.

The animals, which lack a gene that is crucial to the disease’s progression, were not designed for use as food. They were created so that human pharmaceuticals can be made in their blood without the danger that those products might get contaminated with the infectious agent that causes mad cow.

That agent, a protein known as a prion (pronounced PREE-on), can cause a fatal human ailment, variant Creutzfeldt-Jakob disease, if it gets into the body.

More generally, scientists said, the animals will facilitate studies of prions, which are among the strangest of all known infectious agents because they do not contain any genetic material. Prions also cause scrapie in sheep and fatal wasting diseases in elk and minks.

In the future, experts said, similar techniques might be used to engineer animals with more nutritious meats — though the Food and Drug Administration has said it will require engineered food animals to pass tests far more stringent than those it recently deemed adequate for clones.

The Latest in Nanotechnology

Nano-welds herald new era of electronics.

“We can create any 3D shape by varying the beam and rotating the target,” he adds. Using this technique, the researchers have already made nano-scalpels 10 nm by 20 nm across and just a few nanometres thick. These scalpels can be used for cutting into living cells.

U.S. developing nanotech military armor

The U.S. Army awarded a $15 million contract for the development of a new type of lightweight composite armor based on nanotechnology.

Rice said the planned armor “will be even stronger than existing armor, but also lighter, to reduce the top weight of the ‘up-armored’ vehicle.”

He also assured that engineers would be looking into reducing the flammability and flexibility issues inherent in many composite materials as an improvement in body armor.

The Year in Nanotech

Dazzling displays, handheld sensors, cancer killers, and nanotube computers.

Nanocures.
Conventional cancer treatment can wreak havoc on the body. So researchers are developing technology smaller than the cancer cells that can seek them out, slip inside, and deliver a dose of deadly cancer medicine, leaving healthy cells untouched.

As researchers race to develop new cancer-fighting nano tools, an important weapon will be computer modeling, which will help researchers identify materials and structures that can be used safely in the body. (See “Speeding Up Nanomedicine.”) But perhaps the biggest impact of nanotechnology on health could be new ways of using nanostructures to purify water, since dirty water is a leading cause of disease worldwide.

The Latest in Robots

We’ll All be Cyborgs Someday (This link acts weird in Firefox. the second time you visit it, it wil bother you with subscription information. Just use IE to view this, or clean your cookies in Firefox and then revisit the site)

Kevin Warwick, a professor of cybernetics at the University of Reading, has firsthand knowledge. In 1998, he had a chip surgically inserted into his left arm, becoming, he thinks, the first human ever implanted with a computer chip.

Since then, he’s had a more sophisticated chip connected directly to his nervous system. He is still working toward his grandest experiment: having a chip implanted in his brain.

“I want to become a cyborg,” he said with an infectious grin. “I can see the advantages.”

In 2002, doctors sliced open Warwick’s left wrist and implanted a much smaller and more sophisticated device. For three months, its 100 electrodes were connected to his median nerves, linking his nervous system to a computer.

“I moved my hand, and my neural signals were sent over the Internet to open and close a robot hand,” he said.

Not only that: The robotic hand had sensors. As it grasped a sponge or a glasses case, it sent information back to Warwick.

“It was tremendously exciting,” Warwick said. “I experienced it as signals in my brain, which my brain was quite happy to recognize as feedback from the robot hand fingertips.”

A Robot in Every Home

I can envision a future in which robotic devices will become a nearly ubiquitous part of our day-to-day lives. I believe that technologies such as distributed computing, voice and visual recognition, and wireless broadband connectivity will open the door to a new generation of autonomous devices that enable computers to perform tasks in the physical world on our behalf. We may be on the verge of a new era, when the PC will get up off the desktop and allow us to see, hear, touch and manipulate objects in places where we are not physically present.

UK report says robots will have rights

“If we make conscious robots they would want to have rights and they probably should,” said Henrik Christensen, director of the Centre of Robotics and Intelligent Machines at the Georgia Institute of Technology.

Robots and machines are now classed as inanimate objects without rights or duties but if artificial intelligence becomes ubiquitous, the report argues, there may be calls for humans’ rights to be extended to them.

“There will be people who can’t distinguish that so we need to have ethical rules to make sure we as humans interact with robots in an ethical manner so we do not move our boundaries of what is acceptable.”

Robots of the Future

First there was the DARPA Grand Challenge, a robotic contest for building a driverless car capable of successfully completing a 132-mile off-road course. In November 2007, DARPA will throw down the gauntlet once again in the form of the Urban Challenge. This contest raises the bar by requiring its autonomous contestants to negotiate a 60-mile course through simulated urban traffic in less than six hours. Bookies’ favorite is likely to be Sebastian Thrun and his team of roboticists from Stanford University, CA, who won the last challenge, in 2005.


Conscious computing debated at MIT anniversary event

The question of whether machines will be capable of human intelligence is ultimately a matter for philosophers to take up and not something scientists can answer, an inventor and a computer scientist agreed during a debate late last month at the Massachusetts Institute of Technology.

What if your laptop knew how you felt?

Faces reveal emotions, and researchers in fields as disparate as psychology, computer science, and engineering are joining forces under the umbrella of “affective computing” to teach machines to read expressions. If they succeed, your computer may one day “read” your mood and play along. Machines equipped with emotional skills could also be used in teaching, robotics, gaming, sales, security, law enforcement, and psychological diagnosis.

Continued Support From the Glenn Foundation for Medical Research

In response to the recent progress report from Methuselah Foundation chairman Aubrey de Grey, we are pleased to note that the Glenn Foundation for Medical Research has stepped forward in greater support of Foundation-funded SENS research with the offer of an additional $50,000 donation.

Paul F. Glenn, founder of the Glenn Foundation, said, “We have been following the progress of Aubrey de Grey’s ideas with interest, and the Thiel matching pledge allows us to leverage our funds in a highly efficient way.”

Filter removes mad cow proteins from blood

A new filtering device can remove dangerous “mad cow disease” proteins from blood. Scientists say the device could prevent the spread of deadly prion diseases via blood transfusions.

At least three people have died in the UK after receiving blood contaminated with variant Creutzfeldt Jakob disease (vCJD) – the human equivalent of mad cow disease. There is currently no test available to screen blood for the misfolded “prion” proteins that cause the illness.

The new “P-Capt” filter designed by Robert Rohwer of the VA Medical Center in Baltimore, Maryland, US, and colleagues aims to make blood safer by removing these proteins. Their tests show the filter can prevent infections in hamsters and can remove the vCJD prions from human blood.

Military college to set up stem cell research centre

‘Stem cell therapy is the futuristic regenerative or reparative medicine. It will be the futuristic treatment replacing drug therapy and surgery. Through stem cell treatment, heart diseases, diabetes, Parkinson’s disease, epilepsy, multiple sclerosis, eye and muscle disease and various other diseases can be cured,’ Surgeon Vice Admiral V.K. Singh, the Armed Forces Medical Services director general, told IANS.

‘We are not playing god. Our intention is not to create a super human being but to repair diseased and damaged human tissues and organs,’ said Col. Harsh Kumar, head of the Department of Transfusion Medicine, AFMC.

‘Stem cell therapy, a futuristic treatment in medicine, is all set to revolutionise and replace drug-based treatment as stem cells have the potential to form parts of the human body. It is absolutely achievable,’ he added.

The Future of Brain Surgery

With Lasers and Daring, Doctors Race to Save a Young Man’s Brain.

The idea is deceptively simple: instead of cutting a hole in the brain artery and then sewing a vein to it, he sews first and cuts later. That way, the artery does not have to be temporarily clamped, and blood flow to the brain is not cut off. A excimer laser is used to make the hole because it can be slipped into a tight space on the tip of a slender tube and makes a clean cut that stays open without burning nearby tissue.

Major Breakthrough in Aging Research

Dnage Scientists Report Major Breakthroughs In Ageing Research.

While the link between DNA damage and ageing had been established before it has now been shown that the level of “repair-problems” is directly correlated to the severity of the resulting ageing-diseases. The findings indicate that inadequate DNA repair results in accelerated ageing that strongly resembles the processes of natural ageing in older organisms.

Importantly, it was demonstrated that the body activates various natural defence-mechanisms against the accumulation of DNA-damage in order to delay the development of ageing diseases. This indicates that DNA-damage and DNA-repair are very important targets for new products in the field of ageing diseases. Learning from the body’s own response as described by these scientists, the Company is now testing compounds that may eventually lead to products that delay the development of ageing diseases such as Osteoporosis and Neurodegeneration (diseases of the brain including Alzheimer’s and Dementia).

Big news from my home country.

I’ve seen it on the news just a few minutes ago. The spokesperson said that it would take anywhere from 7 to 9 years to develop drugs based on this breakthrough.

With a breakthrough this important, you’d think some people could be moved to action in order to accelerate the realisation of anti aging drugs.

The implications are quite big.

Crysis - Next Gen Game Footage

Crysis Video.

This new video showcases many new Crysis gameplay features and gives a very detailed look at the environments and outlines the story line as well. I think many companies are counting on Crysis as being “the” title to truly kick off DX10 and Windows Vista while being an exciting motivation for more enthusiasts to upgrade their hardware. To put it in technical terms, it looks like the upcoming Crysis is going to kick some serious ass.
