Model of inflatable space hotel set to launch

July 12, 2006

Genesis I, an inflatable spacecraft designed to test technology for a future space hotel is to be launched from Russia on Wednesday by Bigelow Aerospace.

Genesis I is one-third the size of a proposed space hotel that is based on an abandoned NASA concept for an inflatable space station called TransHab.

Bigelow hopes to build the 330-cubic-meter space hotel by 2012. But the lack of a low-cost vehicle… read more

Fuel-Cell Tech May Be Coming Soon

September 3, 2003

Japanese companies are pushing ahead with prototypes of miniaturized fuel cells they say will dramatically improve the battery life of laptop computers. Yet, some experts insist fuel-cell technology is still several years away.

Biotech Company to Auction Chances to Clone a Dog

May 23, 2008

BioArts International will auction off five opportunities to have a dog cloned, with the bidding to start at $100,000.

The company has produced one set of verified dog clones internally. Dogs are among the most difficult animals to clone because they have an unusual reproductive biology, more so than humans. The first cloned dog was born in 2005.

Layered ’2D nanocrystals’ could replace CMOS transistors

Purdue University researchers are developing a new type of semiconductor technology for future computers and electronics that could replace today’s CMOS (complementary metal oxide semiconductor) transistors.

It’s based on “two-dimensional nanocrystals” layered in sheets less than one nanometer thick.

The layered structure is made of a material called molybdenum disulfide, which belongs to a new class of semiconductors — metal di-chalogenides.

The nanocrystals are… read more

Technology Rewrites the Book

July 19, 2006

The print-on-demand business is gradually moving toward the center of the marketplace. What began as a way for publishers to reduce their inventory and stop wasting paper is becoming a tool for anyone who needs a bound document. Short-run presses can turn out books economically in small quantities or singly, and new software simplifies the process of designing a book.

Man gets smartphone dock built into prosthetic arm

October 27, 2011

Trevor Prideaux has become the world’s first patient to have a smartphone (a Nokia C7) docking system built into his prosthetic arm. He was born without his left arm, and had to balance the smartphone on his prosthetic arm or put it on a flat surface to use it.

I wonder if it has an ARM processor? — Ed.

New Theory: Universe Born in a Black Hole

September 19, 2003

The entire universe may have been created in an explosion inside a black hole, says Blake Temple, a mathematician at the University of California, Davis.

The Big Bang is an actual explosion, Temple says, and it occurs within a black hole in an existing space. The shock wave of the explosion is expanding into an infinite space.

Temple also describes the whole scenario as a white hole.

Top Scientific Breakthroughs of 2009

January 4, 2010

A sensor that can smell cancer, a computer program that predicts drug dide effects, and Rapamycin, an immunosuppressant that allowed mice to live an equivalent of 13 extra years were among the stories that made Wired’s list of science breakthroughs in 2009.

Perfect Night Vision? New Superlattice Structure Enables High Performance Infrared Imaging

May 29, 2008

Northwestern University scientists have demonstrated for the first time a high-performance infrared imager based on a Type II superlattice, allowing for more sensitive detection of infrared energy from the human body and other room-temperate objects, which emit infrared signals at around 10 microns.

This new device structure is capable of detecting very low light intensity with high optical efficiency and exhibits an electrical noise level 10 times smaller than… read more

Life After Earth: Imagining Survival Beyond This Terra Firma

August 1, 2006

The Alliance to Rescue Civilization advocates a backup for humanity by way of a station on the Moon replete with DNA samples of all life on Earth, as well as a compendium of all human knowledge.

It would be run by people who, through fertility treatments and frozen human eggs and sperm, could serve as a new Adam and Eve in addition to their role as a new Noah.… read more

Chinese spacecraft dock in orbit

November 3, 2011

Shenzhou 8 craft made contact with Tiangong-1

The unmanned Shenzhou 8 craft, launched earlier this week, has made contact with the Tiangong-1 space lab.

Being able to dock two space vehicles together is a necessary capability for China if it wants to start building a space station towards the decade’s end.

No astronauts were in the Shenzhou craft this time, but future missions will carry people.

Human Genome on Chip Offered by Rivals

October 2, 2003

The genome on a chip has arrived. With pieces of all 30,000 or so known human genes, the new integrated gene chips, or microarrays, will allow scientists to scan all genes in a human tissue sample at once to determine which genes are active (turned on) in an organ compared with those active in a healthy organ. Pharmaceutical companies will use them to predict drug effects.

This previously required… read more

CES 2010: Open Source 3-D Printer Turns Designs Into Objects

January 11, 2010

MakerBot’s Cupcake CNC 3-D Printer, an open-source, $950 kit, allows the user to fabricate small objects of virtually any shape in plastic.

Graphene crowd-surfs on a lipid monolayer

Could provide a versatile new platform for biosensors and drug delivery systems
September 30, 2016

“Crowd-surfing” on a smooth, supportive lipid monolayer, graphene could provide a versatile new platform for biosensors and drug delivery systems, researchers at Leiden University in The Netherlands have discovered.

Graphene is typically supported or sandwiched with other two-dimensional materials to promote higher mobility, ensure consistent electrical performance, and prevent environmental contamination. But combining graphene with soft, dynamic, molecular self-assembled lipid monolayers could provide a versatile platform for applications such… read more
