Scientists claim they can create babies without men by injecting eggs with artificial sperm

The Chinese team says the new discovery could pave the way for exciting new treatments to boost male fertility

Scientists have claimed they have found a way for women to have babies without men by creating artificial sperm.

The team from China claim they have created healthy mouse babies by injecting laboratory-made sperm into eggs to produce mouse offspring.

The scientists claim their stem cell technique could pave the way for new treatments for male fertility.

But British experts have called for the results to be independently verified and pointed out that any practical application is likely to be a long way off.

The mouse cells produced were technically “spermatids” – undeveloped sperm that lack tails and cannot swim.

Yet when they were injected into…

IBM simulates 4.5 percent of the human brain, and all of the cat brain

Supercomputers can store more information than the human brain and can calculate a single equation faster, but even the biggest, fastest supercomputers in the world cannot match the overall processing power of the brain. And they are nowhere near as compact or energy efficient.

Nevertheless, IBM is trying to simulate the human brain with its own cutting-edge supercomputer, called Blue Gene. For the simulation, it used 147,456 processors working in parallel with one another. IBM researchers say each processor is roughly equivalent to the one found in a personal computer, with one gigabyte of working memory.

So configured, Blue Gene simulated 4.5 percent of the brain’s neurons and the connections among them called synapses—that’s about one billion neurons and 10 trillion synapses. In total, the brain has roughly 20 billion neurons and 200 trillion synapses.

IBM describes the work in an intriguing paper (pdf) that compares various animal simulations done by its cognitive computing research group in Almaden, Calif. The group has managed to completely simulate the brain of a mouse (512 processors), rat (2,048) and cat (24,576). To rival the cortex inside your head, IBM predicts it will need to hook up 880,000 processors, which it hopes to achieve by 2019.

Scientist succesfully implant chip that controls the brain

Scientists working at the University of Southern California, home of the Department of Homeland Security’s National Center for Risk and Economic Analysis of Terrorism Events, have created an artificial memory system that allows thoughts, memories and learned behavior to be transferred from one brain to another.

In a scene right out of a George Orwell novel, a team of scientists working in the fields of “neural engineering” and “Biomimetic MicroElectronic Systems” have successfully created a chip that controls the brain and can be used as a storage device for long-term memories. In studies the scientists have been able to record, download and transfer memories into other hosts with the same chip implanted. The advancement in technology brings the world one step closer to a global police state and the reality of absolute mind control.

More terrifying is the potential for implementation of what was only a science fiction fantasy – the “Thought Police” – where the government reads people’s memories and thoughts and can then rehabilitate them through torture before they ever even commit a crime based on a statistical computer analysis showing people with certain types of thoughts are likely to commit a certain type of crime in the future.

We already pre-emptively invade nations and torture alleged terrorist suspects with absolutely no due process of law, so the idea of pre-emptively torturing a terrorist suspect beforehand to prevent them from committing an act of terrorism in the future really isn’t that far fetched of an idea.

Perhaps a less sensational example than those I just depicted from Orwell’s famous dystopian novels would be using the technology as it is depicted the modern day Matrix movies…

Boosting neuron growth may lead to drugs that improve cognition and mood

In Tech on April 4, 2011 at 3:18 pm

By Kurzweil

Researchers at Columbia University Medical Center have developed a new way to stimulate neurogenesis (neuron production) in the adult mouse brain, demonstrating that neurons acquired in the brain’s hippocampus during adulthood improve certain cognitive functions.

The researchers boosted the number of neurons in the hippocampus, an area of the brain involved in memory and mood, and tested the mice in both learning and mood-related tasks, looking for changes in behavior.

They found specific effects on learning tasks that involve a process called pattern separation, which is the ability to distinguish between similar places, events, and experiences. Pattern separation is important for learning, since it helps determine whether something is familiar or novel.

Pattern separation may also be important for anxiety disorders, including…
