Tiny RNA molecules fine-tune the brain’s synapses

January 19, 2006

MicroRNAs, tiny, recently discovered RNA molecules from non-coding regions of the genome that suppress gene expression, affect the development of synapses by regulating the size of dendritic spines.

The findings appear in the January 19th issue of Nature. “This paper provides the first evidence that microRNAs have a role at the synapse, allowing for a new level of regulation of gene expression,” says senior author Michael Greenberg, PhD, Director… read more

Maths gets into shape

April 17, 2003

One simple equation can generate a vast diversity of natural shapes, from simple triangles and pentagons, to stars, spirals and petals.

“Using one formula to produce shapes will make graphics programs much more efficient, he says. It might also be useful in pattern recognition.”

SKA telescope to provide a billion PCs’ worth of processing

September 21, 2009

IBM has a partnership with the US Department of Energy to build a 20 petaflops machine by 2011-2012*, followed by an exaflop machine (10^18 flops), the processing equivalent of about a billion PCs.

IBM is also planning to develop over the next 10 years a machine capable of processing the exabyte (10^18) of data expected to flow per day from the Square Kilometre Array (SKA) telescope project. And the… read more

A realistic bio-inspired robotic finger

Initial use is in underwater robotics
October 9, 2015

Bio-Inspired Robotic Finger-ft

A realistic 3D-printed robotic finger using a shape memory alloy (SMA) and a unique thermal training technique has been developed by Florida Atlantic University assistant professor Erik Engeberg, Ph.D.

“We have been able to thermomechanically train our robotic finger to mimic the motions of a human finger, like flexion and extension,” said Engeberg. “Because of its light weight, dexterity and strength, our robotic design offers… read more

Engineers make first ‘active matrix’ display using nanowires

April 1, 2008

Purdue University researchers have created the first active-matrix display using a new class of transparent nanowire transistors and circuits.

Future applications include e-paper, flexible color monitors, and heads-up displays embedded in car windshields.

Geeks in Toyland

February 1, 2006

When the time came for a major upgrade to Lego’s Mindstorms robot kit, they turned to their obsessed fans — and rewrote the rules of the innovation game.

Autonomous machines, networks, and robots will self-improve in the future by publishing their own upgrade suggestions

The best way for autonomous machines, networks, and robots to improve in the future will be for them to publish their own upgrade suggestions on the Internet, says Sandor Veres of the University of Southampton’s Faculty of Engineering and the Environment.

This leap to increased autonomy will be facilitated by machines and humans publishing information in a common language online.  This can be achieved by… read more

DNA re-write could allay cloning fears

April 30, 2003

An extra step could eliminate many objections to the controversial reproductive cloning technique.

Cloned human embryos would be used to derive healthy sperm and eggs that could subsequently be used for in vitro fertilization rather than implanting the embryo directly into the mother’s uterus.

Embryonic stem cells would be removed and nurtured in the lab. Researchers would then treat the cells with molecules that encourage them to develop… read more

By 2040 you will be able to upload your brain,,,

September 28, 2009

We will be able to upload the human brain to a computer, capturing “a person’s entire personality, memory, skills and history,” by the end of the 2030s; humans and non-biological machines will then merge so effectively that the differences between them will no longer matter; and, after that, human intelligence, transformed for the better, will start to expand outward into the universe, about 2045, says Ray Kurzweil.

Snakelike Robots for Heart Surgery

(Amir Degani)

CardioArm, a snakelike surgical robot from Carnegie Mellon University, could let a surgeon performing a critical heart operation make just one incision.

The curved robot has a series of joints that automatically adjust to follow the course plotted by the robot’s head, operated using a computer and joystick. This provides greater precision than a flexible endoscope can offer.

The smallest version of the device is 300… read more

UK stem cell scientists to recruit egg donors

February 15, 2006

Women in the UK will be allowed to donate their eggs solely for stem cell cloning experiments to find new ways of treating degenerative diseases.

The Human Fertilisation and Embryology Authority proposed the change to help research into therapeutic cloning and address a shortage of donor eggs.

Touchscreen keyboard morphs to fit your typing style

July 26, 2011

IBM Keyboard

IBM recently filed a U.S. patent application for a morphing touchscreen keyboard interface that would automatically resize, reshape, and reposition keys based on a user’s typing style.

IBM proposes a system that would alter the size, shape, and location of keys to suit an individual’s physical anatomy, such as finger size, length, and range of motion. The user would first carry out a series of calibration exercises… read more

Are aliens hiding their messages?

May 8, 2003

Two physicists have come up with an intriguing solution to the Fermi paradox (If we are not alone in the Universe, why have we never picked up signals from an extraterrestrial civilization?).

They suggest a way in which aliens could send messages to each other across space that not only disguises their locations but also makes it impossible for a casual observer to even distinguish the messages from background… read more

Gene Controlling Number Of Brain Cells Pinpointed

October 5, 2009

The GSK-3 gene controls the signals that determine how many neurons end up composing the brain, University of North Carolina reseachers have found.

The finding has important implications for preventing brain tumors and for neuropsychiatric illnesses.

Reprogrammed Stem Cells work on Parkinson’s

April 8, 2008

MIT and Harvard scientists have shown that induced pluripotent stem (iPS) cells can become functioning neurons when transplanted into the brains of mice and rats; they also showed that the cells can improve symptoms in a rat model of Parkinson’s disease.

They used a previously developed method for reprogramming cells, in which skin cells of a mouse can be made pluripotent when infected with a retrovirus carrying four genes.… read more
