More on wireless:

http://www.techreview.com/Infotech/18475/

This time it's Terahertz radiation, which has the potential to carry thousands of times more information than current wi-fi.

For an infrastructure-poor country like India, which depends so much on wireless communication like cellphones, etc, a high-speed terahertz communication network could radically transform society, and make all pre-existing communications technologies obsolete.

Diabetics cured by stem-cell treatment
Diabetics using stem-cell therapy have been able to stop taking insulin injections for the first time, after their bodies started to produce the hormone naturally again.

In a breakthrough trial, 15 young patients with newly diagnosed type 1 diabetes were given drugs to suppress their immune systems followed by transfusions of stem cells drawn from their own blood.

The results show that insulin-dependent diabetics can be freed from reliance on needles by an injection of their own stem cells. The therapy could signal a revolution in the treatment of the condition, which affects more than 300,000 Britons.
Bring it on!

I've known people with the dreadful type I disorder. This is good news indeed.

An alternate idea to the Tokamak based designs that are currently being focused on.
Looks like they've come to a stage where the obstacles are related to engineering rather than design.

Batteries powered by sugar

We got interested in sugar-powered fuel cells after developing ethanol fuel cells and realising that, energetically, it made more sense to use the sugar directly than to turn sugar into ethanol and then use the ethanol. Minteer claims that her "sugar battery" is the longest-lasting and most powerful of its type to date. Sugar (as glucose) powers all living things with nature harnessing the available energy in a series of complex enzyme-driven reactions.

The prototype sugar battery now sitting on Minteer's desk is being used to power a handheld calculator - and, she estimates, the battery has enough sugar left for several years. Minteer claims sugar batteries have the potential to operate three to four times longer on a single charge than conventional lithium ion batteries.

"Each cell gives a voltage of about 0.75V, but has three or four times the energy density of a typical battery, so the battery will last much longer," Minteer says.

You have to stack two sugar battery cells together for a standard 1.5V - some development work is needed before the physical size matches an AA battery.

The sugar battery's green credentials appear compelling and, if carefully designed, could be fully biodegradeable and recyclable too.

Controlled Quantum Coupling Achieved

http://www.wired.com/science/discoverie ... umcoupling

This is a fundamental breakthrough necessary to make quantum computing possible. It is comparable to the idea of the vacuum tube or transistor, as a logic gate or switch.

If quantum computing takes off, then anything and everything could be possible.

Cheap, portable PCR (polymerase chain reaction)

http://www.futurepundit.com/archives/004224.html

I'm sure you all know what this is -- it's DNA amplification. And it's cheap and portable.
Imagine if such devices could even make their way into consumer electronics goods, like cellphones, or electric razors, or something. You might be able to quickly find out what ails you, if it's a common virus or bacteria or something. In the US alone there are hundreds of thousands of hospitalizations every year due to flu and pneumonia. In India, who knows how many we have.

The price of 3D printers (rapid prototyping machines) is now coming down:

http://www.nytimes.com/2007/05/07/techn ... 7copy.html

A company named Desktop Factory has just come out with a model that is below $5000, which puts it in reach for home consumers to buy and use.

This type of affordable system could one day revolutionize the economy and its supply chain, as the electronic blueprints for parts are effortlessly transmitted to any corner of the country, where they would be turned into parts on site.

It would be the equivalent of a fax machine, but for small parts.

This would reduce the burden on a country's transportation system, while also giving the manufacturing supply chain much more flexibility, as small manufacturing shops could easily switch from manufacturing one type of component to another, to fulfill a wide variety of changing market demands.

Scientists create 'plastic' blood

Scientists have developed an artificial plastic blood which could act as a substitute in emergencies.

Researchers at Sheffield University said their creation could be a huge advantage in war zones.

They say that the artificial blood is light to carry, does not need to be kept cool and can be kept for longer.

The new blood is made up of plastic molecules that have an iron atom at their core, like haemoglobin, that can carry oxygen through the body.

The scientists said the artificial blood could be cheap to produce and they were looking for extra funding to develop a final prototype that would be suitable for biological testing.

'Very excited'

Dr Lance Twyman, of the university's Department of Chemistry, said: "We are very excited about the potential for this product and about the fact that this could save lives.

"Many people die from superficial wounds when they are trapped in an accident or are injured on the battlefield and can't get blood before they get to hospital.

"This product can be stored a lot more easily than blood, meaning large quantities could be carried easily by ambulances and the armed forces."

A sample of the artificial blood prototype will be on display at the Science Museum in London from 22 May as part of an exhibition about the history of plastics.

454's Rothberg, Moore's Law

Post by Sanjay M »

I dunno if it's just a biz-man's buzzword, but Jonathan Rothberg is talking about "Genomics 2.0" as a new paradigm in advancing genomics technology:

http://www.bio-itworld.com/newsitems/2007/...othberg-keynote

Well, at least he put his money where his mouth is, and created 454 Life Sciences, and now he's in the middle of creating another venture.

Hehe, I like that -- "Just get the smartest people you can" ;P

Rothberg's latest company is Raindance Technologies:

http://www.raindancetechnologies.com/

When you visit the site, go click on the link to the Technology page. Then click on the various icons in the sidebar.

He's created what he claims is the Laboratory equivalent of the Personal Computer. From what I see, a telecom analogy is more apt -- it's a packet switching network. Instead of a long continuous stream of reagent/sample, you instead have a series of tiny packets (droplets), which are being routed through a network system.

According to the site, these droplets are processed/routed at a rate of 2500 per second! That's approx 10 million per hour -- stunning!

With that many samples being individually analyzed, it would yield so many data points that any biochemical testing could be done with very reliable results.

It would make combinatorial chemistry very efficient. I'm imagining that even non-biotech chemistry, for synthesis of complex nano-devices would be possible.

This device could become a nano-bot factory, as well as bio-engineered organisms.

Imagine an individual nano-bot being formed inside each tiny droplet. Each time a droplet stops to have a procedure performed on it, a new piece is added onto the nano-bot. At 10 million droplets per hour, you could assemble a large army of nano-bots really quickly.

Ewww, that means each droplet would be a -- nano-uterus, or nano-egg, gestating or hatching... nano-embyros?

Well, if millions of tadpoles can be made in a swarm of tiny eggs, then why wouldn't nano-bots be made in the same way? You wouldn't expect it all to be done in one giant open vat, now would you?

A nanotube-reinforced aerogel has been developed, which has the extreme light weight of an aerogel, with the high strength from the nanotube reinforcement:

http://www.physorg.com/news98551391.html

People have talked about the idea of "vacuum lift" technology. This is when you have a chamber made from a strong lightweight material which is enclosing a vacuum cavity.
The result is supposed to be a "buoyancy cell" which is slighter than even a hydrogen balloon.

Maybe this nanotube-reinforced aerogel could be used for just such an application.

This latest announcement on the development of something resembling a BEC using polaritons seems interesting:

http://physorg.com/news98645866.html

http://physicsweb.org/articles/news/11/5/17/1

The announcement says that this "polariton BEC" could generate laser output in a more energy-efficient way than lasers achieved through conventional population inversion of electrons. The "polariton BEC" can apparently also be achieved at temperatures somewhere between liquid nitrogen and room temperature, which sounds more cost-effective.

I'm thinking it could be used particularly to generate high-energy lasers more efficiently, and thus be of assistance in applications like laser-confinement fusion, or maybe directed energy weapons.

Agrichar is a carbon ash product which can be put into soil to make it fertile while also making that same soil a carbon sink.

Move away electrons, photons are here

PIC: photonic integrated circuit

IPO of makers of PIC Infinera corpco-founded by NRI Jagdeep Singh rocked Wall st.
But there is little doubt that the field is hot, and its founders, who have previously built successful networking companies, know their high tech. Om Malik, who runs the U.S.-based technology news Website gigaom.com, wrote that Infinera was comparable to search engine leader Google, Internet phone company Skype (since acquired by eBay) and broadband phone service Vonage.
"The common trait amongst all these companies is the audaciousness of the idea, and the unrelenting desire of the founders to just march to the beat of the drum only they hear. Some have happy endings, others don't," Malik said.

'Free' energy technology goes on display


Technology developed by an Irish firm that allegedly defies basic laws of physics to produce free power today goes on public display for the first time.

Steorn is challenging worldwide cynicism over its claims to have stumbled upon a revolutionary discovery that creates clean, constant energy and could end the global fuel crisis.

While 22 scientists continue their exhaustive tests on the Orbo technology the inventors are asking the public to come and see a demonstration for themselves at Kinetica Museum, Spitalfields Market, London.

A live working demonstration will be streamed on the internet from 6pm tonight. It can be viewed on the web from four different camera angles, before opening to visitors on Thursday.

Sean McCarthy, chief executive of Steorn, said: "What we are showing basically is a very simplified version of the technology. It's virtually all-clear plastic and magnets so we are demonstrating obviously that there is no battery hidden and so on. What the system will be doing is literally lifting a weight, demonstrating work being done for free."

Mr McCarthy said the company decided against using the technology to illuminate a light-bulb because the use of wires would attract further suspicion from a scientific community that has denounced the invention as heretical.

The technology, based on the interaction of magnetic fields, and yet to be conclusively proven or declared a hoax, created a stir after Steorn placed an advertisement in the Economist magazine last year challenging the world's scientists to test its claims.

The company picked 22 of the world's leading scientists from Europe and the US for the review, which started in January and is not expected to be completed before the end of the year.

Mr McCarthy insisted Steorn are contractually obliged to publish whatever the scientists conclude in full, adding that the €8 million invested in the technology to date and the company's reputation were at stake.

"Obviously Steorn and Sean McCarthy would never recover if there is a negative result here. But we don't see that as even an outside possibility," he said.
