Researchers at Rice University have packed an entire lithium ion energy storage device into a single nanowire.

The researchers first reported the creation of three-dimensional nanobatteries last December. In that project, they encased vertical arrays of nickel-tin nanowires in PMMA (Plexiglas) that served as an electrolyte and insulator. They grew the nanowires via electrodeposition in an anodized alumina template atop a copper substrate.

In that… read more

Scientists build DNA nano-devices

January 4, 2002

New York University researchers claim to have taken a major step in building more controllable machines from DNA. The researchers say that the new device may help build the foundation for the development of sophisticated machines at a molecular scale, ultimately evolving to the development of nano-robots that might some day build new molecules, computer circuits or fight infectious diseases.
The research team was led by NYU chemistry professor Nadrian… read more

Scientists Build Memory Chip as Small as Blood Cell

January 25, 2007

Scientists have built a working memory chip with 160,000 bits capacity that is roughly the size of a white blood cell — about 1/2000th of an inch on a side.

The chip has a bit density of 100 billion per square centimeter, about 20 times greater than current memory chips.

A key component of the memory chip is a molecular switch using rotaxanes.

Scientists build mind-reading computer

June 3, 2008

Researchers at Carnegie Mellon University have developed a system that can forecast the activity patterns a brain will create for a specific word.

Subjects were given 58 concrete nouns and asked to think about the meaning and properties of the words. Brain scans taken when the users were thinking about the different words were then captured using magnetic resonance imaging.

The researchers identified a number of the basic… read more

Scientists build polio virus from scratch

July 16, 2002

Scientists have built the virus that causes polio from scratch in the lab, using only genetic sequence information from public databases and readily available technology. The finding raises the possibility that bioterrorists could use a similar approach to create devasting diseases without having to gain access to protected viral stocks.

Scientists build world’s first anti-laser

February 18, 2011

In the anti-laser, incoming light waves are trapped in a cavity where they bounce back and forth until they are eventually absorbed. Their energy is dissipated as heat. (Yidong Chong)

Yale University scientists have built the world’s first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.

Conventional lasers, which were first invented in 1960, use a so-called “gain medium,” usually a semiconductor like gallium… read more

Scientists build world’s first nanofluidic device with complex 3-D surfaces

April 1, 2009

Researchers at the National Institute of Standards and Technology (NIST) and Cornell University have used a process for manufacturing integrated circuits at the nanometer level in designing the first nanofluidic device with complex 3-D surfaces.

Among potential applications: processing nanomaterials for manufacturing; separation and measuring of complex nanoparticle mixtures for drug delivery, gene therapy and nanoparticle toxicology; and isolation and confinement of individual DNA strands for scientific study.

Japanese researchers have created an “artificial neural connection” (ANC) from the brain directly to the spinal locomotion center in the lower thoracic and lumbar regions of the spine, potentially one day allowing patients with spinal-cord damage, such as paraplegics, to walk.

The study led by Shusaku Sasada, research fellow, and Yukio Nishimura, associate professor, both of the National Institutes of Natural Sciences (NINS), was published… read more

Scientists Call for Space Exploration

February 15, 2008

The next president of the United States should give NASA an additional $3 billion each year, both to get to Mars and to focus attention on science issues in space and on Earth, a group of scientists, industry figures and former astronauts said on Thursday.

The group of 50 experts met at Stanford University for a two-day conference to discuss the “Vision for Space Exploration” that President Bush unveiled… read more

Scientists Claim Cloning Success

February 12, 2004

South Korea scientists report that they have created human embryos through cloning and extracted embryonic stem cells.

The development is what patients with diseases like Parkinson’s and diabetes had been waiting for, the start of so-called therapeutic cloning. The idea is to clone a patients cells to make embryonic stem cells that are an exact genetic match of the patient. Then those cells, patients hope, could be turned into… read more

Scientists claim discovery of life coming to Earth from space [UPDATED]

September 20, 2013

SEM_of_a_diatom_frustule

Scientists from the University of Sheffield believe they have found life arriving to Earth from space after sending a balloon 27km into the stratosphere.

After it landed, they discovered that they had captured a diatom fragment and some unusual biological entities from the stratosphere, all of which are too large to have come from Earth, the scientists suggest.

The team was led by Professor… read more

Scientists Claim to Clone Monkey Embryos

November 14, 2007

Oregon National Primate Research Center scientists say they’ve reached the long-sought goal of cloning monkey embryos and extracting stem cells from them, a potentially major step toward doing the same thing in people.

In cloning to obtain stem cells, DNA from an adult animal is inserted into an unfertilized egg. The egg is grown into an early embryo, from which stem cells are extracted. These stem cells, and the… read more

Scientists clone from frozen mice

November 4, 2008

Japanese scientists have created clones from the bodies of mice that have been frozen at -20C for 16 years, raising the possibility of recreating extinct creatures such as mammoths from their frozen remains.

Scientists Clone Mice From Hair Follicle Stem Cell

February 13, 2007

Researchers have cloned mice using stem cells from the rodents’ hair follicle region.

The skin stem cells come from adult mice, are relatively easy to obtain and inject, and may represent a good future source of stem cells for animal cloning.

Scientists close to entering Vostok, Antarctica’s biggest subglacial lake

February 2, 2012

After drilling for two decades through more than two miles of antarctic ice, Russian scientists are on the verge of entering a vast, dark lake that hasn’t been touched by light for more than 20?million years.

This is the first direct contact with what scientists now know is a web of more than 200 subglacial lakes in Antarctica.

Scientists are enormously excited about what life-forms might… read more
