Could Michael Jackson Have Been Cloned?

Dolly, right, the first cloned sheep produced through nuclear transfer from differentiated adult sheep cells, and Polly, the world's first transgenic lamb, are in their pen at the Roslin Institute in Edinburgh, Scotland, in early December, 1997. Scientists at the Roslin Institute produced Molly and Polly cloned with a human gene so that their milk will contain a blood clotting protein that can be extracted for use in treating human hemophilia. Ian Wilmut's technique motivated many governments to ban research on human cloning. Dolly was later naturally mated and gave birth to a healthy lamb. (AP Photo/John Chadwick)

From Live Science:

Michael Jackson reportedly was very interested in being cloned.

"I really want to do it Uri, and I don’t care how much it costs," he is said to have told Uri Geller, a self-proclaimed psychic who claims to bend spoons with his mind (boy, if I had that power I'd sure use it for something besides spoon-bending!).

Whether the news report is accurate or not, the fact is the science didn't advance soon enough for Jackson. There have been no substantiated claims of cloned human embryos grown into fetal stages and beyond, despite rumors to the contrary. The capability to so do is near, however.

10 Wind Turbines That Push the Limits of Design

From Popular Mechanics:

The American Wind Energy Association (AWEA) released their 20% Wind Report Card on July 8, following up on a study in which the Department of Energy proposed a goal where 20 percent of U.S. electricity comes from wind energy by 2030. The AWEA gave the overall U.S. push for wind power a “solid B”—high marks from an advocacy group that grades U.S. infrastructure. The highest letter in the report was an A- awarded for “Technology Development.” This is no big surprise—for years now, the government, alternative-energy researchers and entrepreneurs have been putting time and money into making better tech for cleaner, more efficient energy production. Here are 10 wind turbine designs that push the limits of the current design and may help the U.S. get back to being an A student by 2030.

This Message Will Self Destruct: Scientists Develop Programmable, Self-Erasing Documents

Self-Erasing Documents Powered By Disappearing Nanoparticles

From Popsci.com:

Researchers are harnessing nanoparticle properties to develop fading ink.

Remember when, as a kid, you would pass “top-secret” notes written in lemon juice that your friends could only read in the right light? Well, in light of new nanotechnology research, this now sounds absurdly antiquated, like cave painting in the modern era. Instead, the youth of the future (and adults, too) could have to option to communicate via documents that self-erase at a programmed time.

Ball Aerospace: Where Satellites Come From

Space-Based Surveillance Satellite courtesy Ball Aerospace & Technologies

From Popsci.com:

PopSci visits the Colorado facility of the company that makes satellites, advanced instruments, and mason jars.

When it comes to space, what goes up must be sturdy, safe and secure if it's to live very long. Satellites must survive the bone-rattling jostle and pressure of launch, and once they reach orbit, they've got to weather the vast temperature changes they experience with every sunrise and sunset. Their skins must be thick enough to survive pummeling by micro-debris, and they'd better have trusty gyroscopes to be able to change directions or keep their balance.

That's why space-bound objects undergo thorough testing at firms like Ball Aerospace & Technologies Corp., builders of satellite skeletons, gyroscopes, advanced instruments, and mason jars. (Well, that's a different division.)

California Gives Desalination Plants a Fresh Look

From The Wall Street Journal:

Process to Make Seawater Drinkable Gains Traction, but Environmentalists Object to Heavy Energy Use, Harm to Marine Life.

Early next year, the Southern California town of Carlsbad will break ground on a plant that each day will turn 50 million gallons of seawater into fresh drinking water.

The $320 million project, which would be the largest desalination plant in the Western Hemisphere, was held up in the planning stages for years. But a protracted drought helped propel the project to its approval in May -- a sign of how worried local authorities are about water supplies.

Phantom Menace To Dark Matter Theory

Image: The answer to the riddle of dark matter could be found in our own solar system (Image: NASA)

From New Scientist:

A SUBTLE anomaly in the orbit of the planets in our solar system could prove a controversial idea that goes beyond Einstein.

The orbit of the innermost planet, Mercury, departs from what it should be under Newton's laws. A century ago, when Einstein explained this anomaly, it confirmed his theory of gravity - the general theory of relativity.

Now an Israeli physicist predicts that a similar but far more subtle anomaly in the orbits of the planets, if detected, might prove his own theory, known as modified Newtonian dynamics, or MOND. This provides an alternative theory to dark matter to explain why stars orbiting at the edge of spiral galaxies are not flung out into space. These stars are travelling at speeds too fast for conventional gravity from the mass at the heart of a spiral galaxy to hold them in their orbits, so something else must be keeping them on track.

New Wonder Material, One-Atom Thick, Has Scientists Abuzz

Graphene has been described as a carbon nanotube unrolled. Its two-dimensional sheet is made up of a single layer of carbon atoms arranged in a hexagonal pattern like a honeycomb. Electrons can move ballistically through these sheets even at room temperature, making graphene a prime target of the electronics industry. image from Science@Berkeley Lab

From McClatchy News/Yahoo News:

WASHINGTON — Imagine a carbon sheet that's only one atom thick but is stronger than diamond and conducts electricity 100 times faster than the silicon in computer chips.

That's graphene, the latest wonder material coming out of science laboratories around the world. It's creating tremendous buzz among physicists, chemists and electronic engineers.

"It is the thinnest known material in the universe, and the strongest ever measured," Andre Geim , a physicist at the University of Manchester, England , wrote in the June 19 issue of the journal Science.

Rubik Cube Inventor Devises New Puzzle To Drive Us All To Distraction

From Times Online:

His cube was one of the most popular and infuriating toys of all time. Now Professor Ernö Rubik is hoping that the sphere will bring sleepless nights to the world’s obsessive puzzlers.

The creator of Rubik’s Cube is back with his first new puzzle for almost 20 years and early indications are that it is going to be every bit as irritating as the original.

Rubik’s 360, which goes on sale next week, features six small balls inside three interlocking spheres. The task is to lock each ball into colour-coded capsules on the outermost sphere. Professor Rubik said of his cube that it was “easy to understand the task, but hard to work out the solution”. It is just as aggravating to crack the 360.

From Time Magazine:

A natural compound, used as an immunosuppressant in organ-transplant patients, has been found to extend life in mice, according to a study published Wednesday by the journal Nature. Aging mice that were given the substance, rapamycin, lived significantly longer than mice that didn't get the drug: females that received rapamycin were 13% older at death, and males 9% older.

The research, conducted as part of the National Institute of Aging Interventions Testing Program, took place at three separate test sites and involved nearly 2,000 genetically similar mice. Trials began when mice were about 600 days old — well into middle age, at a stage roughly equivalent to 60-year-old humans.

From Science Daily:

ScienceDaily (July 8, 2009) — Fear is a powerful emotion, and neuroscientists have for the first time located the neurons responsible for fear conditioning in the mammalian brain. Fear conditioning is a form of Pavlovian, or associative, learning and is considered to be a model system for understanding human phobias, post-traumatic stress disorder and other anxiety disorders.

Using an imaging technique that enabled them to trace the process of neural activation in the brains of rats, University of Washington researchers have pinpointed the basolateral nucleus in the region of the brain called the of amygdala as the place where fear conditioning is encoded.

Laughter: Not Just For Funny Stuff

Laughter comes in two main types, scientists found. Credit: Dreamstime

From Live Science:

Scientists say there are two types of laughter: the kind that comes from pure glee, and the kind that's meant to send a social message. New research suggests autistic children don't often express the latter type, a finding that could reveal more about the nature of human laughter.

Laughter probably predates human speech by millions of years, scientists think. It likely evolved as an early form of communication to help people negotiate group dynamics and establish hierarchy, said William Hudenko, a psychologist at Ithaca College who led the new study.

Babies usually learn to laugh before they learn to speak.

Europe Targets Manned Spaceship

From The BBC:

Europe has taken the first step towards building its own manned spaceship.

The European Space Agency has asked industry to work out the requirements of the craft and its likely cost.

Known as the Advanced Re-Entry Vehicle, it would be developed in phases - first as an unmanned vessel to carry cargo, and then as an astronaut crew ship.

At the moment, Europe has no independent capability to transport humans into space and must hitch rides on American or Russian systems.

Was Ancient Earth A Green Planet?

From The New Scientist:

Earth's landmasses in the late Precambrian probably weren't pleasant, but at least they were green. A new analysis of limestone rocks laid down between 1 billion and 500 million years ago suggests that there was extensive plant life on land much earlier than previously thought.

The plants were only tiny mosses and liverworts, but they would have had a profound effect on the planet. They turned the hitherto barren Earth green, created the first soils and pumped oxygen into the atmosphere, laying the foundations for animals to evolve in the Cambrian explosion that started 542 million years ago.

Scientists Create 'Artificial Brain Cell'

From The Telegraph:

Scientists have created an artificial brain cell they believe could one day be used to treat devastating neurological diseases.

The team has managed to pass messages within the mind in the same way as nerve cells, using a tiny piece of plastic which can transmit electricity.

These messages are used by the brain to control many actions in the body.

Correcting when they go awry could be the key to treating some diseases like Parkinson's disease researchers believe.

Human Sperm Created From Stem Cells In World First, Claims British University

From The Telegraph:

British scientists have created human sperm using stem cells in a medical first that could revolutionise fertility treatment, they claim.

Researchers at the pioneering Northeast England Stem Cell Institute say they have made the breakthrough using stem cells from an embryo.

They claim that with some minor changes the sperm could theoretically fertilise an egg to create a child.

Within 10 years, the scientists say the technique could also be used to allow infertile couples to have children that are genetically their own. It could even be possible to create sperm from female stem cells, they say, which would ultimately mean a woman having a baby without a man.

New Evidence That Vinegar May Be Natural Fat-fighter

Found in many salad dressings, pickles, and other foods, vinegar could help prevent accumulation of body fat and weight gain, scientists report. (Credit: Wikimedia Commons)

From Science Daily:

ScienceDaily (July 7, 2009) — Researchers in Japan are reporting new evidence that the ordinary vinegar — a staple in oil-and-vinegar salad dressings, pickles, and other foods — may live up to its age-old reputation in folk medicine as a health promoter. They are reporting new evidence that vinegar can help prevent accumulation of body fat and weight gain.

Tomoo Kondo and colleagues note in the new study that vinegar has also been used as a folk medicine since ancient times. People have used it for a range of ills. Modern scientific research suggests that acetic acid, the main component of vinegar, may help control blood pressure, blood sugar levels, and fat accumulation.

Humans Ate Fish 40,000 Years Ago

Chinese fishermen haul in the catch of fish from the frozen Chagan Lake in Songyuan, northeast China's Jilin province on December 25, 2008, at the start of the winter fishing season. Chagan Lake covers an area of 259 square kilometers and is one of the 10 largest freshwater lakes in China, where each winter, fishermen use the ancient method of breaking the ice with wooden stakes before placing their nets to harvest the fish.

From Live Science:

At least one of our ancestors regularly ate fish 40,000 years ago, a new study finds.

Scientists analyzed chemical compositions of the protein collagen in an ancient human skeleton from Tianyuan Cave near Beijing to reach their conclusion.

Fishing at this time must have involved considerable effort, the researchers think, because fossil records suggest humans were not using sophisticated tools — beyond crude stone blades — until about 50,000 years ago.

Ray Kurzweil on How to Combat Aging

From Technology Review:

The noted futurist says that exponential advances will allow us to intervene in the aging process.

Submitted in response to Technology Review's interview with Leonard Hayflick. See "Can Aging Be Solved?"

Entropy is not the most fruitful perspective from which to view aging. There are varying error rates in biological information processes depending on the cell type, and this is part of biology's paradigm. We have means already of determining error-free DNA sequences even though specific cells will contain DNA errors, and we will be in a position to correct those errors that matter.
