New Kind of Search Engine

This one doesn't just provide links, like Google. Wolfram/Alpha gives you meaningful data back. Type in a company name and get the stock quote, type in a calculation and it gives you the answer, type in a date and it gives you information about sunrise, day of year, etc. It gives scientific answers, chemistry answers, culture - Oh just go there by clicking on the link above and have some fun.

Mini Satellite, Big Payload

A 10 pound tiny satellite, shaped like a loaf of bread, called PharmaSat lifted off from a US Air Force four-stage Minotaur 1 rocket on May 5. The satellite will circle the Earth at 17,000 mph while carrying a micro-laboratory packed with sensors and optical systems.

The launch is hailed a the beginning of a revolution where the size and weight of spacecraft decline steadily, but retain much of the capabilities of its larger brethren.

PharmaSat is being launched to help NASA scientists better understand how medications work during space flights. Focusing on antifungal treatments, the microlab on board the satellite is designed to detect the growth, density and health of yeast cells and then send that data back to Earth for analysis. The satellite is also built to monitor the levels of pressure, temperature and acceleration that the yeast and the satellite experience while orbiting the globe. It also will prove that biological experiments can be conducted on sophisticated autonomous nanosatellites.

More Robot Stuff







Albert Hubo is 3.3-foot-tall battery-powered walking humanoid with realistic, human like facial expressions. The robotic body was developed by researchers at the Korea Advanced Institute of Science and Technology, and the head is a creation of Hanson Robotics, a Texas company that makes interactive conversational robots.

Artificial Legs

The picture is a twenty dollar prosthetic knee joint, developed by Stanford’s JaipurKnee Project team, during prototype testing last August. The knee joint was on display April 8, 2009 at the university.

The team studied the mechanics of high-end titanium knee joints in the US, which cost from $10,000 to $100,000. The team also surveyed the materials used to build cheap prosthetics for developing countries and designed a versatile knee joint made from an oil-filled nylon polymer. The self-lubricating joint has greater flexibility, demonstrating a much higher performance.

They fitted 43 of these joints to date in India, for field tests to improve the model. The plan is to produce 100,000 during the next few years. One more example of how healthcare does not have to be expensive.

Wallpaper TV

Coming to a wall near you.

Many of us are accustomed to watching TV on high-quality flat screens, but now Toshiba has come up with a new solution. It is a flexible paper that doubles as a TV screen.

The paper uses light that has been redirected using a fine grating created by self-assembling nano-particles. In addition to projecting moving and still pictures, the paper could also be used to emit light, eliminating the need for traditional lighting.

I won't go into details of the cool OLED technology used, but the basic materials have been around since the 90s. Television wallpaper is currently in the early stages of research and won't be on your wall for quite sometime. Wow, I don't even have an HDTV yet and they are already on their way out. The speed of technology change is so exciting, I can hardly stand it.

Nanotube Radio

The nanotube radio, invented in 2007, performs a set of amazing feats: a single carbon nanotube tunes in a broadcast signal, amplifies it, converts it to an audio signal and then sends it to an external speaker in a form that the human ear can readily recognize. You can visit www.sciam.com/nanoradio and listen to a song.

Can you imagine hearing aids and cell phones small enough to fit completely within the ear canal. The nanoradio is actually small enough to fit inside a living cell. Wish they could invent a device of any size that did not have commercials.

Light a Picture


This is so ridiculous that I first thought it was an April Fool's joke, but it is not. A group at MIT proposed the idea of a matchstick embedded with a tiny camera and microphone (green half) and micro projector (red half).

A user swipes the red side of the match, physically lighting it on fire. This sets off the camera and microphone to start recording, moving down the length of the match in response to heat. The match stores the image and sound in the middle. When a user lights the other end, a mini projector plays back the video once before burning away (literally). The group has so far designed a prototype, based on two coupled matches synced to a computer webcam and playback program. A one-time recorder and playback might be a fun party trick and a fleeting reminder to appreciate moments, but it's still a stupid idea.

Phones as Computers

As testament to the changing use of phones, consider the following. At North America's largest cell phone trade show in Las Vegas this month, there were only a few new phones for the US market that had a numeric keypad instead of an alphabetic keyboard. Touch screens also were out in force.

These changes are a recognition of the popularity of text messaging and wireless Internet use. Industry organization CTIA Wireless said US subscribers sent 1 trillion text messages in 2008 (three times the 2007 volume). Meanwhile, the same people used 2.2 trillion minutes of voice calls, an increase of less than 5 percent.

This shift in how people use their mobile devices has changed cell phone design to the point that 31 percent of phones sold in US in the fourth quarter of 2008 had full-alphabet keyboards, vs. 5 percent two years earlier. u me lunch, k?

Flat Speakers


Wow, these are cool. New loudspeakers, less than 0.25mm thick, have been developed. They are flat, flexible, can be hung on a wall like a picture.

A real bonus is that its method of sound generation could make public announcements in public places clearer, crisper, and easier to hear because it delivers planar directional sound waves, which project further than sound from conventional speakers. I think they will fit nicely on the wall beside my flat screen TV, if I ever get one.

Patently Obvious


Did you know Michael Jackson has a patent? Remember how he leaned in defiance of gravity in the video for “Smooth Criminal”?
He wore a pair of specially designed shoes that could hitch into a device hidden beneath the stage. Jackson and two co-inventors patented this method for creating anti-gravity illusion in 1993.

Brain control


March 31, 2009 - The research wing of Honda Motor Co. has co-developed a brain-machine interface system that allows a person to control a robot through thought alone. The system, builds on previous work announced three years ago toward a future in which devices might be controlled by thought.

In 2006, Honda and ATR researchers managed to get a robotic hand to move by analyzing brain activity using a large MRI (magnetic resonance imaging) scanner like that found in hospitals.

The latest work is a step more advanced and measures the electrical activity in a person's brain using EEG and blood flow within the brain using near-infrared spectroscopy to produce data that is then interpreted into control information. It requires no physical movement.

Both the EEG and NIRS techniques are established, but the analyzing process for the data is new. Honda said the system uses statistical processing of the complex information to distinguish brain activities with high precision without any physical motion. A person visualizes moving a hand yet physically remains completely still, then Honda's Asimo robot, to which the system is hooked-up, raises its right hand. Honda claims a 90% success rate using this method.

Hey, Asimo, get me a beer!

Google Voice

This new service is about to be launched. It has been in test for some time. Call it the "one number to rule them all" service. Users will be able to register, sign up for a phone number in a local area code, and add multiple land line and cell-phone numbers to an account. When someone calls a Google Voice phone number, all the registered phones ring at the same time.

The service takes several telephony technologies and connects them to the Web. It's the voice equivalent of an e-mail address. Once you register a number you never have to worry about which phone you are using, even if you switch offices, homes, or cell phones. You can even press 4 to record a current call.

No matter which phone you use, there is one portal for all voice-mail messages. You can play them on the Web, save them as MP3 files, and even post a voice-mail message on a website. Conference calls are also easy. Answer an incoming call to add it to the current one. Very cool technology, but that record feature is a bit too scary for me. I like to keep my rants current, and not have someone save them for posterity.

I have my beta invite, because I was signed up with GrandCentral, which is the foundation technology for Google Voice.

Toilet Seat scale


Check this out. I think it is a bit odd, but some think it is a very neat idea.

More Bathroom Goodies



Here is a 2.4 GHZ wireless toothbrush camera. You can now inspect your teeth anywhere, just hook it to your computer and get a dentist's eye view of what is going on in your mouth. Might be good to help you find that nagging popcorn kernel. There is also a USB model with wires, but it is messy to use.

Telling Time the Hard Way

Here is a robotic clock. Fully functional, accurate, interesting for a minute, but not very practical.

Speaking of Inspiring


Here is the latest effort to mimic the human brain on a chip.
A collaboration with neurobiologists and contributions of 15 scientific groups from seven different countries, the group is trying to recreate the three-dimensional structure of the brain in a 2-D piece of silicon. The current prototype can operate about 100,000 times faster than a real human brain.

The FACETS group now plans to further scale up their chips, connecting a number of wafers to create a superchip with a total of a billion neurons and 1013 synapses. Roomba has been eclipsed.

Toothbrush Fountain


Here is a novel idea from Amron Experimental.

This is a toothbrush that redirects water to your mouth so you don't need a glass or get your hands wet. They are cheap at $1.18. I bet the kids would love this. Of course my first test would be to see how far it would shoot.

Bionic Eyes

The artificial eyes use a camera and video processor mounted on sunglasses to send captured images wirelessly to a tiny receiver on the outside of the eye. In turn, the receiver passes on the data via a tiny cable to an array of electrodes which sit on the retina - the layer of specialized cells that normally respond to light found at the back of the eye.

When these electrodes are stimulated they send messages along the optic nerve to the brain, which is able to perceive patterns of light and dark spots corresponding to which electrodes have been stimulated. The hope is that patients will learn to interpret the visual patterns produced into meaningful images.

The bionic eye has been developed by US company Second Sight. So far 18 patients across the world have been fitted with the device. One totally blind man, who had seen total blackness for 30 years, reports being able to sort out socks by color, see white lines on the road, and more. The technology still a long way to go, but this is major progress.

Email to Home Address

How about this for a new concept, you can mail or receive mail electronically to your home address. This site has set up an email for every home address. Free for personal use, cheap for bulk mailers. It takes input directly from billing systems and sends them off to your street address. You open it like an email. It might work once more people know of it. For now, I'm not sure, but it would save the trip to the mailbox to collect paper to throw in the trash. You can just hit the delete button, or better yet, don't open the mail and you will never see it.

Nanotechnology

The easiest way to describe the size of a nanometer is by comparison. If a baseball is a nanometer, the whole earth would be a meter. A meter is 39 inches and a yard is 36 inches.

The Wilson Double Core tennis ball, the official ball of the Davis Cup tournament, has clay nanoparticles embedded in the polymer lining of its inner wall, which slows the escape of air from the ball, making it last twice as long.
