VR treatment for stroke patients announced

January 28, 2002

Rutgers researchers have filed a patent application for a PC-based virtual- reality system that provides stroke patients hand-impairment therapy. In use, the patient’s gloved hands are linked to virtual hands on the PC monitor, so the patient’s actual hand movements are mimicked on-screen. By interacting and playing with on-screen graphics — including fluttering butterflies, piano keyboards and mechanical hands — the patient performs intensive rehab exercises without drudgery, according to… read more

VR headset spots concussion in minutes

April 28, 2005

A virtual-reality headset is being developed that can diagnose the extent of a head injury within minutes.

The system puts the wearer through an array of neuropsychological tests designed to pick up reduced reaction times and deficits in working memory, conditions that would indicate injuries to different parts of the brain.

By measuring reaction times in a battery of tests, the system is designed to detect even mild… read more

VR hallucinations used to treat schizophrenia

July 2, 2002

A virtual reality environment has been designed by a team at the University of Queensland in Brisbane to help treat people with schizophrenia, using a simulated living room projected onto a wrap-around screen and a soundtrack with an abusive running commentary.
For example, it can mimic common hallucinations: walls appear to be closing in, photographs of faces morph, straight lines such as the edge of pictures wobble. The idea is… read more

VR and Haptics for Rehabilitation

March 26, 2010

At the IEEE’s Virtual Reality 2010 conference, researchers and companies are demonstrating technologies that combine virtual reality and haptics, some designed for medical rehabilitation.

VR accommodates reality

August 4, 2003

Researchers have advanced the representatiom of real objects in virtual environments by allowing real and virtual objects to coexist in a shared virtual space.

The system uses four cameras and object recognition software to determine the shapes and positions of real objects in the environment. The camera data is used to generate virtual three-dimensional shells in the shapes of the real objects, and the shells are forbidden zones for… read more

Voyager 1 embarks on historic journey into interstellar space

September 13, 2013

NASA‘s Voyager 1 spacecraft is now officially the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun.

New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas, present in the space between stars. Voyager is in a transitional region immediately outside… read more

Voyage of the Bacteria Bots

Researchers at the Ecole Polytechnique de Montreal have coupled live, swimming bacteria to 150-nanometer beads to develop a self-propelling “nanobot” device steered through the body using magnetic resonance imaging (MRI).

The bacteria swim at 200 microns/second using tiny corkscrewlike tails, or flagella, and are just two microns in diameter–small enough to fit through the smallest blood vessels in the human body. The beads are treated with antibodies… read more

Volvo’s first self-driving cars now being tested live on public roads in Swedish city

Volvo Car Group’s “Drive Me” project — featuring 100 self-driving Volvos on public roads in everyday driving conditions — is moving forward rapidly, with the first test cars now driving around the Swedish city of Gothenburg.

“The test cars are now able to handle lane following, speed adaption, and merging traffic all by themselves,” says Erik Coelingh, Technical Specialist at Volvo Car Group.

“This is an important step… read more

Volvo’s autonomous cars travel 124 miles in Spain in ‘road train’

May 31, 2012

Volvo has tested its fuel-saving”road train” technology on public roads in Spain, finding the historic test “highly successful.”

Volvo used one lead vehicle and four trailing vehicles — consisting of a Volvo S60, a Volvo V60 and a Volvo XC60 plus a truck — that drove autonomously for 200 kilometers (124 miles) at 85 kilometers an hour (53 miles per hour) on the roads outside Barceolona.

Members of the public are being asked to join the hunt for nearby planets that could support life.

Volunteers can go to the Planethunters website to see time-lapsed images of 150,000 stars, taken by the Kepler space telescope. They will be advised on the signs that indicate the presence of a planet and how to alert experts if they spot them.

“We know that people will… read more

The next step in the evolution of connected cars is making cars intelligent.

The goal of the Urban Intelligent Assist project, which Audi is undertaking in collaboration with four U.S. universities, is to help the driver deal with driving conditions and navigation.

The goal is for the cars to recognize individual motorists behind the wheel, and know preferred destinations, routes the motorists have most commonly traveled, and the time… read more

Volkswagen shows off self-driving autopilot technology for cars

June 24, 2011

Volkswagen has presented its “Temporary Auto Pilot” technology. Monitored by a driver, the technology can allow a car to drive semi-automatically at speeds of up to 80 mph on highways.

It works using a combination of existing technology such as adaptive cruise control and lane-keeping assist, rolling them all into one comprehensive function.

In the semi-automatic driving mode, the system maintains a safe distance to the vehicle ahead,… read more

Volcanoes may reveal secrets through ‘song’

August 10, 2006

Active volcanoes are being made to “sing” by researchers who convert seismic data into frequencies audible to human ears.

The sonification ttechnique could make it easier to detect patterns that warn of an eruption.

Volcano could trigger tsunami disaster for New York

August 11, 2004

A collapsing volcano could trigger a vast tidal wave capable of wiping New York, Washington and Miami off the map, warn geologists.

Geologists are concerned that an unstable flank of the Cumbre Vieja volcano on the island of La Palma in the Canaries is in danger of sliding into the sea.

If shaken loose by a volcanic eruption, the huge slab of rock would send a tsunami more… read more

Volcanic lightning may have sparked life on Earth

October 17, 2008

Scientists have detected additional amino acids in the original samples from the classic Miller-Urey experiment: a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids.

But one of the two lesser-know experimental setups — a volcanic apparatus adding steam — created 22 amino acids that could be positively identified, and… read more
