Translation Software Enables Efficient Storage of Massive Amounts of Data in DNA Molecules

Posted by in categories: biotech/medical, genetics

ADS Codex translates binary data into nucleotides that can be sequenced in molecules as files for later retrieval, bringing potential cost savings and compact ‘cold storage.’

In support of a major collaborative project to store massive amounts of data in DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Caltech’s New Space-Based Solar Project Could Power Our Entire Planet /

Posted by in categories: solar power, space, sustainability

It’s the stuff of science fiction: Solar panels in space that beam power directly to Earth equipping the planet with clean renewable and affordable energy. Yet, it could soon be reality.

Caltech has just received $100 million in funding for their Space Solar Power Project (SSPP). The project is described by Caltech as: “Collecting solar power in space and transmitting the energy wirelessly to Earth through microwaves enables terrestrial power availability unaffected by weather or time of day. Solar power could be continuously available anywhere on earth.”

“This ambitious project is a transformative approach to large-scale solar energy harvesting for the Earth that overcomes this intermittency and the need for energy storage,” said SSPP researcher Harry Atwater in the Caltech press release on the matter.

Scientists Shorten Daddy Long-Legs’ Iconic Limbs to Figure Out How They Got So Gangly

Posted by in categories: biotech/medical, genetics

Through a process known as RNA interference (RNAi), scientists have been able to modify the genetic make-up of the daddy long-legs arachnid so that its distinctive spindly limbs become twice as short.

This process – which uses a gene’s own DNA sequence and small fragments of RNA to turn the gene off – was applied to the Phalangium opilio species, one of the most common species of daddy long-legs in the world.

The result is effectively a daddy short-legs instead of a daddy long-legs. The team behind the work is hoping that the experiments can teach us more about how these elongated limbs evolved in the first place.

Scientists Just Simulated Quantum Technology on Classical Computing Hardware

Posted by in categories: quantum physics, robotics/AI

Lurking in the background of the quest for true quantum supremacy hangs an awkward possibility – hyper-fast number crunching tasks based on quantum trickery might just be a load of hype.

Now, a pair of physicists from École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and Columbia University in the US have come up with a better way to judge the potential of near-term quantum devices – by simulating the quantum mechanics they rely upon on more traditional hardware.

Their study made use of a neural network developed by EPFL’s Giuseppe Carleo and his colleague Matthias Troyer back in 2,016 using machine learning to come up with an approximation of a quantum system tasked with running a specific process.

CRISPR Stops Rare Genetic Disease In Groundbreaking Human Trial

Posted by in categories: biotech/medical, genetics

Gene-editing technique CRISPR may deliver new treatments for genetic diseases—and it’s already being tested on patients.


17:22 minutes.

In one of the first clinical applications of the technique, last month researchers reported in the New England Journal of Medicine that CRISPR had stopped a genetic disease called amyloidosis, which occurs when an abnormal protein accumulates in your organs. They’re not the only group moving toward using CRISPR on humans; recently, the FDA approved a human clinical trial that will use the technique to edit genes responsible for sickle cell disease.

SpaceX starlink allows users to download a movie in less than 1 minute

Posted by in categories: internet, satellites

The download speed is 100 Mbps and the upload speed is 13.89 Mbps.


“Starlink” is a satellite internet project of SpaceX. From 2,019 to 2,024 SpaceX plans to use five years to send thousands of satellites needed for networking into low-Earth orbit to form a “Starlink” network to provide internet services. Currently, there are 1,650 satellites on the “Starlink” network.

The Speedtest report shows that in the second quarter of this year, the average download speed of Starlink satellite internet services in the US market was 97.23 Mbps. This is not far from the average download speed of fixed broadband in the US, which is 115.22 Mbps.

AI Wrote Better Phishing Emails Than Humans in a Recent Test

Posted by in categories: cybercrime/malcode, government, information science, robotics/AI

Natural language processing continues to find its way into unexpected corners. This time, it’s phishing emails. In a small study, researchers found that they could use the deep learning language model GPT-3, along with other AI-as-a-service platforms, to significantly lower the barrier to entry for crafting spearphishing campaigns at a massive scale.

Researchers have long debated whether it would be worth the effort for scammers to train machine learning algorithms that could then generate compelling phishing messages. Mass phishing messages are simple and formulaic, after all, and are already highly effective. Highly targeted and tailored “spearphishing” messages are more labor intensive to compose, though. That’s where NLP may come in surprisingly handy.

At the Black Hat and Defcon security conferences in Las Vegas this week, a team from Singapore’s Government Technology Agency presented a recent experiment in which they sent targeted phishing emails they crafted themselves and others generated by an AI-as-a-service platform to 200 of their colleagues. Both messages contained links that were not actually malicious but simply reported back clickthrough rates to the researchers. They were surprised to find that more people clicked the links in the AI-generated messages than the human-written ones—by a significant margin.

Want to pretend to live on Mars? For a whole year? Apply now

Want to find your inner Matt Damon and spend a year pretending you are isolated on Mars? NASA has a job for you.

To prepare for eventually sending astronauts to Mars, NASA began taking applications Friday for four people to live for a year in Mars Dune Alpha. That’s a 1,700-square-foot Martian habitat, created by a 3D-printer, and inside a building at Johnson Space Center in Houston.

New tool maps cell types in lab-grown blobs of brain tissue

Posted by in categories: genetics, mapping, neuroscience

A new tool helps researchers explore the types of cells that make up brain organoids — clusters of cells that can mimic the basic structure, function and development of different parts of the brain.

The software, detailed in Cell Stem Cell, maps information about when and where genes are expressed in brain organoids onto a reference atlas of the developing mouse brain. Scientists can use the resulting overlay to develop organoids that better recapitulate the developing brain, the team says, or to uncover the effects of gene mutations and other experimental perturbations.

Brain organoids derived from the cells of people with conditions such as autism have proved useful in capturing neuronal abnormalities. But the findings are muddied by methodological differences in how researchers develop these lab-grown blobs. Advanced techniques to profile gene expression in single cells have made it easier to identify the cell types in any given organoid. But it’s remained difficult to map those cell types onto different brain regions.
