An under-researched mechanism in the fast-moving field of epigenetics

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

A key epigenetic mark can block the binding of an important gene regulatory protein, and therefore prohibit the gene from being turned off, a new UNSW study in CRISPR-modified mice—published this month in Nature Communications —has shown.

The study has implications for understanding how epigenetics works at a molecular level—and down the track, the scientists hope the research will help them to investigate new treatments for disorders.

“Epigenetics looks at how non-permanent, acquired chemical marks on DNA determine whether or not particular are expressed,” study leader and UNSW Professor Merlin Crossley says.

Scientists Eliminate Drug Side Effects by Manipulating Molecular Chirality

Posted by in categories: biotech/medical, nanotechnology

Scientists from Hong Kong Baptist University (HKBU) have developed a novel technique that can produce pure therapeutic drugs without the associated side effects.

The approach, which uses a nanostructure fabrication device, can manipulate the chirality of drug molecules by controlling the direction a substrate is rotated within the device, thus eliminating the possible side effects that can arise when people take drugs containing molecules with the incorrect chirality.

Published in the renowned international scientific journal Nature Chemistry, the research findings pave the way towards the mass production of purer, cheaper, and safer drugs that can be made in a scalable and more environmentally-friendly way.

Are we ready for the artificial womb?

Posted by in categories: biotech/medical, law

Are you interested in having children, but turned off by the whole pregnancy thing? Well, there may be an option available in the not-too-distant future. The artificial womb — or at least the ability to create one — is inching its way toward us. The big question is whether or not society is ready for it.

The obstacles to ectogenesis — development of the fetus outside of a mother from fertilization to full-term infancy — will soon be dominated more by legal and ethical matters than by technological and medical limitations. Those who embrace technology without reservation may be waiting with open arms. But there will certainly be others who find the prospect disturbing.

Samsung develops new security chip for smartphones

Posted by in categories: computing, mobile phones, security

Samsung has launched a new secure element (SE) chip to protect private and sensitive data on mobile devices, the company said on Tuesday.

The chip, dubbed S3FV9RR, will be offered as a standalone turnkey with security software, Samsung said.

Common Criteria, which certifies the security level of IT products from EAL0 to EAL7 with seven being the most secure, gave the security chip a Common Criteria Evaluation Assurance Level (CC EAL) 6+ certification.

For The First Time, Scientists Achieve ‘Liquid Light’ at Room Temperature

Posted by in category: futurism

Circa 2018


In June 2017, physicists achieved ‘liquid light’ at room temperature for the first time ever, making this strange form of matter more accessible than ever.

This matter is both a superfluid, which has zero friction and viscosity, and a kind of Bose-Einstein condensate — sometimes described as the fifth state of matter — and it allows light to actually flow around objects and corners.

Fly with the Jetman | Yves Rossy

Posted by in category: entertainment

http://www.ted.com Strapped to a jet-powered wing, Yves Rossy is the Jetman — flying free, his body as the rudder, above the Swiss Alps and the Grand Canyon. After a powerful short film shows how it works, Rossy takes the TEDGlobal stage to share the experience and thrill of flying.

‘Digital smell’ technology could let us transmit odors in online chats

Posted by in categories: augmented reality, food, internet, neuroscience, virtual reality

“It’s not just about the smell,” said Adrian Cheok, one of the scientists behind the experiments. “It is part of a whole, integrated virtual reality or augmented reality. So, for example, you could have a virtual dinner with your friend through the internet. You can see them in 3D and also share a glass of wine together.”

In real life, odors are transmitted when airborne molecules waft into the nose, prompting specialized nerve cells in the upper airway to fire off impulses to the brain. In the recent experiments, performed on 31 test subjects at the Imagineering Institute in the Malaysian city of Nusajaya, researchers used electrodes in the nostrils to deliver weak electrical currents above and behind the nostrils, where these neurons are found.

The researchers were able to evoke 10 different virtual odors, including fruity, woody and minty.

First Object Teleported from Earth to Orbit

Posted by in categories: encryption, quantum physics, satellites

Essentially a quantum radar teleportation device could entangle objects anywhere in the universe.


Last year, a Long March 2D rocket took off from the Jiuquan Satellite Launch Centre in the Gobi Desert carrying a satellite called Micius, named after an ancient Chinese philosopher who died in 391 B.C. The rocket placed Micius in a Sun-synchronous orbit so that it passes over the same point on Earth at the same time each day.

Micius is a highly sensitive photon receiver that can detect the quantum states of single photons fired from the ground. That’s important because it should allow scientists to test the technological building blocks for various quantum feats such as entanglement, cryptography, and teleportation.

Why “utility fogs” could be the technology that changes the world

Posted by in category: robotics/AI

Circa 2012


Arthur C. Clarke is famous for suggesting that any sufficiently advanced technology would be indistinguishable from magic. There’s no better of this than the ultra-speculative prospect of “utility fogs” — swarms of networked microscopic robots that could assume the shape and texture of virtually anything.

New Plant-Based Bottles Made From Plant Sugar Degrade in a Year

Posted by in categories: chemistry, food, sustainability

A new “all-plant” drink bottle is underway at a Netherlands biochemicals company. These bottles are made from sustainable crops and decompose within a year.

The bottle is made from plant sugars instead of traditional fossil fuels. Avantium is the company behind the bottle. They have already found support from beer company Carlsberg, who plans to sell a plant-plastic lined cardboard bottle in future beverage releases. Coca-Cola and Danone have also backed the product.

Avantium’s chief executive, Tom van Aken told the Guardian that the plan should be finalized by the end of the year, with the bottles hitting supermarket shelves by 2023. “This plastic has very attractive sustainability credentials because it uses no fossil fuels, and can be recycled – but would also degrade in nature much faster than normal plastics do,” says Van Aken.
