Skin layer grown from human stem cells could replace animals in drug and cosmetics testing

April 28, 2014

iPSC-derived keratinocytes colonies

An international team led by King’s College London and the San Francisco Veteran Affairs Medical Center (SFVAMC) has developed the first lab-grown epidermis (the outermost skin layer) with a functional permeability barrier akin to real skin.

The new epidermis, grown from human pluripotent stem cells, offers a cost-effective alternative lab model for testing drugs and cosmetics, and could also help to develop new therapies for rare and… read more

Skin to Stem Cell Breakthrough Promises Health Care Revolution

March 31, 2009

A new stem-cell technique discovered by Japanese scientist Shinya Yamanaka creates stem cells without using and destroying human embryos and allows for testing drugs for genetic diseases.

Skin used to transmit key data

August 6, 2004

Ident Technology has developed a system that transfers a tiny 30-nanoamperes electric current across the skin to control devices such as a car lock or computer securely by simply touching them.

Since it’s based on an electrostatic effect, it can also work at up to a meter away.

‘Skin-tenna’ wireless signals creep over human skin

A wireless antenna that channels signals along human skin could broadcast signals over your body to connect up medical implants such as pacemakers or portable gadgets.

Developed at Queen’s University in Belfast, the new design’s ability to produce signals that travel along the skin makes it more efficient than existing battery-hungry technologies such as Bluetooth.

Skinput turns your arm into a touchscreen

March 1, 2010

Researchers at Carnegie Mellon University and Microsoft Research have developed a new skin-based interface called Skinput that allows for using hands and arms as touchscreens.

Skinput works by detecting the various ultralow-frequency sounds produced when tapping different parts of the skin, allowing users to control audio devices, play games, make phone calls, and navigate hierarchical browsing systems.

A keyboard, menu, or other graphics are beamed onto a user’s… read more

Skip Your Veggies? Not So Fast

February 13, 2006

A recently published study of 48,835 women, questioning low-fat diets, had serious design defects, experts say.

Subjects with “healthier” diets cut calories from fat by only 8.2 percent compared with the normal group and ate only 1.1 additional servings of fruits and vegetables a day — too small a difference to expect health benefits.

And hy focusing only on total fat intake, the study misleadingly failed to distinquish… read more

SKorea to build top-speed information highway

February 3, 2009

South Korea will install a nationwide 1 Gbps super-broadband infrastructure by 2013 that would enable downloading a feature film in one to two seconds, according to the state-run National Information Society Agency.

Skull echoes could become the new passwords for augmented-reality glasses

May 2, 2016

SkullConduct ft

German researchers have developed a biometric system called SkullConduct that uses bone conduction of sound through the user’s skull for secure user identification and authentication on augmented-reality glasses, such as Google Glass, Meta 2, and HoloLens.

SkullConduct uses the microphone already built into many of these devices and adds electronics (such as a chip) to analyze the frequency response of sound after it travels through the user’s skull. The… read more

Skull electrodes give memory a boost

August 13, 2010

University of Sydney researchers have developed the first non-invasive method of stimulating the brain that can boost visual memory. It uses transcranial direct current stimulation (tDCS), in which weak electrical currents are applied to the scalp using electrodes.

The method can temporarily increase or decrease activity in the anterior temporal lobe (ATL), an area near the temple, and has already been shown to boost verbal and motor skills in volunteers.

Skulls gain virtual faces

August 25, 2003

Max Planck Institute for Computer Science researchers have computerized the process of reconstructing a face from the skull.

The method reverses the process used in facial modeling and animation of shaping anatomical structures to fit a given 3D skin model. It takes less than a day for a computer reconstruction compared to weeks for a traditional clay model.

Skydiver gears up for record free fall

May 26, 2008

Michel Fournier, 64, plans to jump from a balloon at 130,000 feet and free-fall at up to 932 mph an hour (1.7 times the speed of sound), smashing through the sound barrier and landing by parachute in Saskatchewan, Canada.

He hopes to bring back data that will help astronauts and others survive in the highest of altitudes, and break the record for the fastest and longest free fall, the… read more

Skylifter airship could carry 150-ton buildings

October 11, 2010

Skylifter (Skylifter)

Australian company SkyLifter has designed a heavy-lifting, vertical ascent and descent aircraft that will operate as a practical flying crane.

The aircraft is designed to take off where helicopters leave off, with vertical pickup and delivery capability of over-size, fragile or bulky items up to 150 tons, and potentially more. The long flight duration of 24 hours ensures a good distance range and adds flexibility to logistics.… read more

Skylon spaceplane gathers momentum

September 21, 2010

(Reaction Engines)

U.K.-based Reaction Engines’ Skylon plane is designed to take a 12-ton payload  of cargo and passengers into space from a conventional airport and return them back down to the same runway.

The concept for the Skylon is based on a synergistic air-breathing rocket engine (SABRE) that uses jet propulsion to reach the edge of the Earth’s atmosphere before switching to rocket power to get into orbit.… read more
