A ’3D printer’ for customized small molecules such as drugs

March 12, 2015

3D Printer for Small Molecules1

Howard Hughes Medical Institute scientists have developed a simpler way to synthesize small molecules, eliminating a major bottleneck in creating new medicines.

As the scientists note in the March 13, 2015, issue of the journal Science, “small-molecule syntheses typically employ strategies and purification methods that are highly customized for each target, thus requiring automation solutions to be developed [inefficiently] on an ad hoc basis.”

According to Martin Burke, an… read more

Scientists at the Universities of Sheffield and Sussex are embarking on an ambitious project to produce the first accurate computer models of a honeybee brain in a bid to advance our understanding of Artificial Intelligence (AI) and how animals think.

The team will build models of the systems in the brain that govern a honeybee’s vision and sense of smell. Using this information, the researchers… read more

The FDA has told 23andMe, Inc., the Google-backed DNA analysis company cofounded by Anne Wojcicki, to halt sales of its Saliva Collection Kit and Personal Genome Service (PGS).

In a letter, the FDA said the company was acting “without marketing clearance or approval in violation of the Federal Food, Drug and Cosmetic Act (the FD&C Act)….”

“Most of the intended uses for PGS listed on your… read more

A 3D-printed Moon base baked from lunar dust

March 20, 2013

sinterhab-moon-base-4

Space architects have unveiled a concept for a 3D-printed Moon base called SinterHab near the lunar south pole. Modules would be constructed from lunar dust by microwave sintering and contour crafting, built by a large NASA spider robot.

Unlike an earlier, more bulky concept using a mobile printing array of nozzles on a 6 meter frame to spray a binding solution (glue) onto… read more

Apple’s first AI paper focuses on creating ‘superrealistic’ image recognition

December 28, 2016

Simulated+Unsupervised learning ft

Apple’s first paper on artificial intelligence, published Dec. 22 on arXiv (open access), describes a method for improving the ability of a deep neural network to recognize images.

To train neural networks to recognize images, AI researchers have typically labeled (identified or described) each image in a dataset. For example, last year, Georgia Institute of Technology researchers developed a deep-learning method to recognize images taken at regular… read more

Blue Brain project accurately predicts connections between neurons

In a landmark paper, published this week in PNAS (forthcoming), the EPFL’s Blue Brain Project (BBP) has identified key principles that determine synapse-scale connectivity by virtually reconstructing (in supercomputer) a cortical microcircuit and comparing it to a mammalian sample.

These principles now make it possible to predict the locations of synapses in the neocortex, the researchers say.

“This is a major breakthrough,… read more

Non-invasive brain-to-brain interface: links between two brains

Direct communication between the brains of human and rat .... or between humans
April 8, 2013

brainstorm

We reported last month how Duke University researchers remotely linked the brains of two rats. Now researchers from the U.S and South Korea have have taken it a step further: a non-invasive functional link between the brains of different species (human and rat) — a brain-to-brain interface (BBI).

Researchers at Brigham and Women’s Hospital and Harvard Medical School set up a system intended to allow a human to… read more

3D printed meat development funded

August 17, 2012

Billionaire investor Peter Thiel’s philanthropic foundation has announced a six-figure grant for bioprinted meat, part of an ambitious plan to bring to the world’s dinner tables a set of technologies originally developed for creating medical-grade tissues, CNET reports.

The recipient of the Thiel Foundation’s grant, a Columbia, Mo.-based startup named Modern Meadow, is pitching bioprinted meat as a more environmentally-friendly way to satisfy… read more

How the Bolshoi simulation evolves the universe all over again
October 3, 2012

cosmic_web

Most of the ordinary matter in the universe — the stuff that makes up all the atoms, stars, and galaxies astronomers can see — is invisible, either sprinkled throughout intergalactic space in tenuous forms that emit and absorb little light or else swaddled inside galaxies in murky clouds of dust and gas, Joel R. Primack writes in IEEE Spectrum.

When astronomers look out into the night… read more

A bucket-full of this material can absorb all the oxygen in a room

The stored oxygen can be easily released again whenever and wherever needed

A new crystalline material absorbs 160 times more oxygen than in the air around you — only a spoonful bucket-full (10 liters) of it is enough to suck up all the oxygen in a room, according to its developer, Professor Christine McKenzie in the Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark.

A few grains of this material might absorb enough oxygen from the… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more

Tesla autopilot predicts

Hans Noordsij, a Dutch Tesla driver, uploaded a Dec. 27 dashcam video that dramatically shows the new radar processing capacity of Tesla’s Autopilot and resulting auto-breaking, DarkVision Hardware reports. The system’s radar saw ahead of the car in front and tracked two cars ahead on the road. Note the audible warning a second or so before the accident.
