Giving a PC a robotic neck and throwing away the keyboard and mouse has produced a less-demanding personal computer controlled only by gestures.
California Institute of Technology computer scientists have succeeded in building a DNA crystal that computes as it grows.
This is the first time that a computation has been embedded in the growth of any crystal, and the first time that computation has been used to create a complex microscopic pattern.
The scientists showed that DNA “tiles” can be programmed to self-assemble into a crystal, using DNA “sticky ends”… read more
With the help of new high-speed DNA sequencing technology, scientists have uncovered extensive regions in the human genome where chunks of DNA have been deleted, copied, or completely rearranged.
Mapping and characterizing these structural variants could be key to understanding human diversity and the origins of many diseases.
Intel has unveiled for New York Fashion Week the My Intelligent Communication Accessory (MICA) message display device, PC World reports.
The 1.6-inch sapphire-glass touchscreen can display SMS messages relayed through the bracelet’s Intel XMM6321 3G cellular radio. It can also display calendar alerts.
The MICA bracelet also follows Intel’s acquisition of health-tracking wristband maker Basis Science in March.
Dramatic improvements in speech discernment using signal processing have been developed by Stanford University professor of electrical engineering Bernard Widrow and his students.
Dr. Widrow reported the breakhrough in a keynote speech at the recent annual meeting of the Acoustical Society of America.
The Directional Hearing ARray (D-HEAR) uses six tiny microphones and signal-processing electronics (worn as a necklace) to enable people with profound… read more
“I was quite positively impressed [with Wolfram Alpha],” said Cyc creator Doug Lenat. “As [Stephen Wolfram] said, it’s not AI, and not aiming to be, so it shouldn’t be measured by contrasting it with HAL or Cyc but with Google or Yahoo.
“While there are a large range of queries can’t parse, and a large range of parsable queries it can’t answer, it handles a huge range of numeric… read more
Roboticist Hans Moravec has founded Seegrid Corporation to develop vision-enabled robotic carts that can be loaded and then walked through various routes to teach them how to navigate on their own and move supplies around warehouses without human direction.
A futuristic scheme to collect solar energy on satellites and beam it to Earth has gained a large supporter in the US military.
A report released yesterday by the National Security Space Office recommends that the US government sponsor projects to demonstrate solar-power-generating satellites and provide financial incentives for further private development of the technology. Unlike solar panels based on the ground, solar power satellites placed in geostationary orbit… read more
A system for bar-coding DNA using brilliant crystals called quantum dots could revolutionize our ability to identify genes in the human genome.
A group at Indiana University in Bloomington has developed a way to embed quantum dots in tiny Styrofoam-like beads attached to DNA to create unique labels. The paper
appears in Nature Biotechnology.
The dots are semiconductor crystals of cadmium selenide wrapped in shells of… read more
DARPA’s National Cyber Range will mimic the hardware that might be used to inflict cyber-attacks and the likely behaviors of the people behind them.
A voicemail system that labels messages according to the caller’s tone of voice could soon be helping people identify which messages are the most urgent.
The software, called Emotive Alert, works by extracting the distribution of volume, pitch and speech rate – the ratio of words to pauses – in the first 10 seconds of each message, and then comparing them with eight stored “acoustical fingerprints” that roughly represent… read more
Radar Networks has introduced Twine, a Web 3.0 service that uses semantic Web technology to improve sharing information with friends and coworkers.
Twine is intended to let you suck in email, bookmarks, RSS news feeds, websites, photos, videos, database and any other digital information. Then it tries to make sense of it by extracting and categorizing information automatically.
Individuals can sign up to be invited to the beta… read more
For the first time, nearly all the proteins from a single organism have been produced, purified and biochemically tested in an area the size of a postage stamp. Experts say such “proteome chips” will revolutionize medicine and biology.
The US researchers who created the chip have already used it to study the biochemistry of 93 per cent of the proteins of brewer’s yeast Saccharomyces cerevisiae, a total of 5800 molecules.… read more
Biomedicine, technology, and wireless communication are in the midst of a merger that will easily bring continuous, 24×7 monitoring of several crucial bodily functions in the years ahead.
