Closing in on a cure for vision loss

Scientists believe they may be on the cusp of developing a possible cure for some types of blindness, The Wall Street Journal reports.

Several potential fixes — including gene therapy, stem-cell therapy and a modified version of vitamin A — are currently being tested in people with a rare eye disorder called Stargardt disease.

The work, if it pans out, could pave the way… read more

Closest asteroid yet flies past Earth

October 3, 2003

An asteroid about the size of a small house passed just 88,000 kilometres from the Earth on Saturday 27 September — the closest approach of a natural object ever recorded.

Closer encounter: Nasa plans landing on 40m-wide asteroid travelling at 28,000mph

May 9, 2008

NASA plans to use Orion, the Space Shuttle replacement, for a three to six month round-trip to an asteroid, with astronauts spending a week or two on the rock’s surface.

The mission will give space officials a taste of more complex missions, and samples taken from the rock could help scientists understand more about the birth of the solar system and how best to defend against asteroids that veer… read more

Cloning, germ warfare and GM crops

February 6, 2002

The biotech industry is under siege. It is faced with campaigns against cloning and GM crops — while trying to tackle the potential disaster of germ warfare. Undaunted, the European Commission, which wants to make Europe a front-runner in this fast-moving sector, has just released a policy paper, Life Sciences and Biotechnology – A Strategy for Europe. The goal is an all-encompassing biotechnology framework, a hugely ambitious project that will… read more

Cloning to revive extinct species

May 28, 2002

Using polymerase chain reaction (PCR), geneticists at the Australian Museum are working to revive the Tasmanian Tiger, which has been extinct for 65 years.

This breakthrough allows the scientists to produce millions of pure copies of undamaged DNA fragments, which they believe can work in a living cell. No other long extinct species has ever been cloned.

Cloning to revive extinct species

June 17, 2002

Australian scientists say they are on the way to reviving a previously extinct species — the Tasmanian Tiger (Thylacine) — using cloning technology. The last one died in captivity around 65 years ago. Geneticists working for the Australian Museum said they had successfully replicated Thylacine DNA using a process called polymerase chain reaction (PCR).

This breakthrough allows the scientists to produce millions of pure copies of undamaged DNA fragments… read more

Cloning Said to Yield Human Embryos

January 18, 2008

Scientists at Stemagen, a small biotechnology company, say they have used cloning to create human embryos from the skin cells of two men.

Although the embryos grew only to a very early stage, the work could also theoretically be seen as a step toward creating babies that are genetic copies of other people. The work also represents a step toward the promise of creating personalized embryonic stem cells that… read more

Cloning quantum information from the past

January 8, 2014

In the film "Looper," time travel is invented by the year 2074 and, though immediately outlawed, is used by criminal organizations to send those they want killed into the past where they are killed by "loopers." (Credit: TriStar Pictures)

It is theoretically possible for time travelers to copy quantum data from the past, according to three scientists in a recent paper in Physical Review Letters.

It all started when David Deutsch, a pioneer of quantum computing and a physicist at Oxford, came up with a simplified model of time travel to deal with the Grandfather paradox*.  He solved the paradox originally using a slight change to quantum theory,… read more

Cloning Nanotubes

December 14, 2006

Researchers at Rice University have demonstrated that carbon nanotubes can be chopped into small pieces to form “seeds” that grow more nanotubes of precisely the same type.

The method could eventually make it possible to grow large amounts of carbon nanotubes with identical structure and properties, which could pave the way for vastly improved electrical transmission lines and ultracompact, high-performance computers.

Cloning from the dead claim attacked

September 1, 2004

Viable embryos have been created from dead people by fusing their cells with empty cow eggs, a controversial fertility scientist, Panayiotis Zavos, claimed on Tuesday.

However, the claims were immediately met with both revulsion and scepticism from the UK scientific community.

Cloning First for Horse Family

May 28, 2003

Scientists in the United States have announced the birth of the world’s

first cloned mule. The foal is nearly a month old and appears to be

perfectly healthy. The scientist in charge of its creation says that

“We found calcium seems to be critically important for equine

reproduction. Once we boosted the level of calcium in our culture medium

we started seeing results.” Male show-jumping… read more

‘Cloning’ could make structurally pure nanotubes for nanoelectronics

May be key to separating electrical conductors and semiconductors
November 16, 2012

Cloning nanotubes: In this computer model, small, pre-selected nanotube "seeds" (yellow) are grown to long nanotubes of the same twist or "chirality" in a high-temperature gas of small carbon compounds (Credit: Jia Liu et al./USC)

A technique for growing virtually pure samples of single-wall carbon nanotubes (SWCNTs) with identical structures has been demonstrated by researchers from the University of Southern California (USC) and the National Institute of Standards and Technology (NIST).

They liken this process to “cloning” the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubesread more

Cloning and the New Jacobins

August 20, 2001

A curious coalition of the religious right and anti-science left has been
whipping up a storm about the idea of a nationwide, or even worldwide ban on
human reproductive cloning lately — an example of the clash of visions
between the Lockean, Burkean, and Rousseauean temperaments in Anglosphere
politics.

Cloned Pigs Differ From Originals In Looks And Behavior

April 17, 2003

Another cloning myth shattered. New research at North Carolina State University’s College of Veterinary Medicine indicates that cloned animals do not retain the physical and behavioral attributes of the animal from which they were cloned, “so you cannot expect your cloned pet to behave like your original pet,” said Dr. Jorge Piedrahita, professor of molecular biomedical sciences at NC State.

Cloned Mice Die Young, Japanese Team Finds

February 11, 2002

Japanese researchers who cloned a dozen mice reported on Sunday that virtually all of the animals died early, a report that casts more doubts on the safety of cloning.
The mice had abnormal livers, lungs and perhaps some immune system anomalies, the team reported.

They also noted that clones may be born
“old.” Some clones have shortened telomeres, which are a kind of cap on the chromosome, the structures… read more
