Scientists successfully grow human brain equivalent to 5-week-old foetus in the lab

Posted by in categories: chemistry, neuroscience

Growing brain tissue in a dish has been done before, but bold new research announced this week shows that scientists’ ability to create human brains in laboratory settings has come a long way quickly.

Researchers at the Ohio State University in the US claim to have developed the most complete laboratory-grown human brain ever, creating a model with the brain maturity of a 5-week-old foetus. The brain, which is approximately the size of a pencil eraser, contains 99 percent of the genes that would be present in a natural human foetal brain.

“It not only looks like the developing brain, its diverse cell types express nearly all genes like a brain,” Rene Anand, professor of biological chemistry and pharmacology at Ohio State and lead researcher on the brain model, said in a statement.

Synthetic biology – the next big thing

Posted by in categories: biotech/medical, chemistry, nanotechnology

Synthetic biology programming microorganisms to perform some new functions. Genes are made out of DNA; synthetic biology involves inserting synthetic genes that might not have existed before into yeast and reprogramming them to make a new chemistry or things not made naturally by biology. Each gene codes for an enzyme. One can program a new set of enzymes and convert them to intermediate products. If you go through five or even 15 steps, you can get a final product – a polymer, a new drug – creating a chemical factory inside a cell. This is much better than nanotechnology, because in synthetic biology, we get down to molecular size…


Prof. Joseph Jacobson, a leading physicist at the Massachusetts Institute of Technology, is not only the inventor of e-ink but also a mover in creating artificial DNA to eventually cure diseases.

Affordable genetic diagnostic technique for target DNA analysis developed

Posted by in categories: biotech/medical, chemistry, engineering, genetics

Professor Hyun-Gyu Park of the Department of Chemical and Biomolecular Engineering at Korea Advanced Institute of Science and Technology (KAIST) has developed a technique to analyze various target DNAs using an aptamer, a DNA fragment that can recognize and bind to a specific protein or enzyme. This technique will allow the development of affordable genetic diagnosis for new bacteria or virus, such as Middle Ease Respiratory Syndrome (MERS). The research findings were published in the June issue of Chemical Communications, issued by the Royal Society of Chemistry in the United Kingdom. The paper was selected as a lead article of the journal.

Molecules Have Been Built Using a Laser Beam for the First Time

Posted by in categories: chemistry, futurism

It’s official: Star Trek-style replicators are on the way. Well, sort of. Assembly lines for specific molecules could be a thing of the future, thanks to a recent breakthrough in atomic bonding published in the journal Physical Review Letters. A team of scientists has found a way of using laser beams to control the path of chemical processes, possibly ushering in a new age of photochemistry.

“OS FERMENTATION events have included installations, workshops, prints, and tastings. The installation includes digital prints created by custom electronics and software that allow microbes to take their own “selfies” and add image manipulation effects to their images based on the shifting pH levels, oxygen, and color values of the fermentation process.”

Our Universe is Fine Tuned for Life—Why?

Posted by in categories: astronomy, chemistry, cosmology, gravity, physics, space

Consider how many natural laws and constants—both physical and chemical—have been discovered since the time of the early Greeks. Hundreds of thousands of natural laws have been unveiled in man’s never ending quest to understand Earth and the universe.

I couldn’t name 1% of the laws of nature and physics. Here are just a few that come to mind from my high school science classes. I shall not offer a bulleted list, because that would suggest that these random references to laws and constants are organized or complete. It doesn’t even scratch the surface…

Newton’s Law of force (F=MA), Newton’s law of gravity, The electromagnetic force, strong force, weak force, Avogadro’s Constant, Boyle’s Law, the Lorentz Transformation, Maxwell’s equations, laws of thermodynamics, E=MC2, particles behave as waves, superpositioning of waves, universe inflation rate, for every action… etc, etc.

For some time, physicists, astronomers, chemists, and even theologians have pondered an interesting puzzle: Why is our universe so carefully tuned for our existence? And not just our existence—After all, it makes sense that our stature, our senses and things like muscle mass and speed have evolved to match our environment. But here’s the odd thing—If even one of a great many laws, properties or constants were off by even a smidgen, the whole universe could not exist—at least not in a form that could support life as we imagine it! Even the laws and numbers listed above. All of creation would not be here, if any of these were just a bit off…

Terminator draws closer with shape-shifting liquid metal motor

There are some concepts from sci-fi that really should never, ever see the light of day. The T-1000 — the murderous robot made of shifting liquid metal — is arguably one of them, but that doesn’t mean it doesn’t exhibit some interesting ideas, even if they do seem impossible.

Seem, of course, being the operative word — because researchers in China have just created the world’s first liquid metal robot that can both change shape and power itself.

“The soft machine looks rather intelligent and [can] deform itself according to the space it voyages in, just like [the] Terminator does from the science-fiction film,” Jing Liu from Tsinghua University in Beijing, China, told New Scientist. “These unusual behaviours perfectly resemble the living organisms in nature.” Read more

A Hair Salon Guru’s Next Big Thing: Ending Shampoo

Posted by in category: chemistry

Hair 2

“I honestly think in five years people are going to go, ‘Oh God, remember when we used to wash our hair with shampoo?’” says Michael Gordon. That’s a striking statement, given Gordon’s own history: He created the famed haircare company Bumble and Bumble in 1977, the spin off product line in 1992, and then in 2006 sold his stake to Estée Lauder. But he isn’t advocating for unwashed hair. He’s explaining Purely Perfect, his new product line that defies just about every expectation most consumers have when it comes to personal hygiene.

The marquee product is a hair cleanser that has no detergents and doesn’t create a foam. Specifically, it’s free of sodium laureth sulfate, a chemical ingredient used in virtually all shampoos because it kills oils and leaves users with a squeaky-clean scalp. Problem is, that also dries out skin and hair follicles—a problem that most people treat by buying, without batting an eye, additional products like conditioners and hair masks. Instead, the Purely Perfect cleansing creme has aloe vera, rose flower oil, evening primrose oil, and peppermint oil. Using it feels nothing like shampoo: Massage the balm into your scalp, through your strands, and rinse it out. That’s it. No lathering, no rinsing, no repeating. And no Bumble and Bumble.
