According to Samir Mathur. professor of physics at The Ohio State University, the recently proposed idea that black holes have “firewalls” that destroy all they touch is wrong. He believes that a black hole converts anything that touches it into a hologram — a near-perfect copy of itself that continues to exist just as before.

A decade of work at Johns Hopkins has yielded a computer program that predicts, with far more accuracy than current methods, which mutations are likely to have the largest effect on the activity of the “dimmer switches” (which alter the cell’s gene activity) in DNA — suggesting new targets for diagnosis and treatment of many diseases.

Researchers in Canada and the U.K. have sequenced and assembled de novo (from the ground up) the full genome of a living organism, the bacteria Escherichia Coli, using Oxford Nanopore’s MinION device, a genome sequencer that can fit in the palm of your hand.
The findings, published today in the journal Nature Methods, provide proof of concept for the new genome sequencer technology.
The researchers expect to use… read more

Carnegie Mellon University (CMU) scientists have for the first time documented the actual formation of newly learned concepts inside the brain.
Thanks to recent advances in brain imaging technology at CMU and elsewhere, it is now known how specific concrete objects are coded in the brain — neuroscientists can identify which object, such as a house or a banana, someone is thinking about from its… read more

Sergiu Pasca, M.D., of Stanford University and colleagues have developed “human cortical spheroids” — miniature cultured 3-D structures that grow and function much like the cortex of the brain of the person from whom they were derived.
These “organoids” (3-D complexes of cells that function like an organ) buzz with neuronal network activity. Cells talk with each other in circuits, much as they do in our brains.… read more
Researchers at Missouri University of Science and Technology have developed a “no-ink” color printing process using nanomaterials, with features visible only with the aid of a high-powered electron microscope.
The researchers describe their printing method in an open-access article in the latest issue of Nature Publishing Group’s Scientific Reports and illustrate their technique by reproducing the Missouri S&T athletic logo on a nanometer-scale surface.… read more

University of Cincinnati and university and industry partners have developed a technology for tunable window tinting that dynamically adapts for brightness, color temperatures (such as blueish or yellowish light), and opacity (to provide for privacy while allowing 90 percent or more of the light in), adjustable by the user.
According to the researchers, these “smart windows” are would be simple to manufacture, making them affordable for business… read more

Cornell University engineers have created a functional, synthetic immune organoid (a lab-grown ball of cells with some of the features of a normal organ) that produces antibodies. The engineered organ has implications for everything from rapid production of immune therapies to new frontiers in cancer or infectious disease research.
The first-of-its-kind immune organoid was created in the lab of Ankur Singh, assistant professor of mechanical and aerospace engineering, who applies… read more

A team of IBM researchers in Zurich, Switzerland with support from colleagues in Yorktown Heights, New York has developed a relatively simple, robust and versatile process for growing crystals made from compound semiconductor materials. The new method will allow the materials to be integrated onto silicon wafers — an important step toward making future computer chips that will allow integrated circuits to continue shrinking in size and cost,… read more
Researchers from Lehigh University, Japan, and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating what they call the “world’s first fully functioning single-crystal waveguide in glass.”
In an open-access article published in Scientific Reports, a Nature publication, the group said it had employed ultrafast femtosecond lasers to produce a three-dimensional single crystal capable of guiding light waves through… read more

In a world first, U.S. and Chinese scientists have developed a method to inject microelectronic devices such as wires and transistors directly into the brain (or other body parts) to measure or stimulate neural activity. The new method could lead to sophisticated new ways to treat conditions ranging from neurodegenerative disorders to paralysis.

In a clinical study, Spanish researchers have used a Microsoft Kinect to help stroke patients increase their ability to use a paralyzed arm.
Stroke patients with “hemiparesis” —- reduced muscle strength on one side of the body — often under-use their affected limbs even though they still have some motor function. A long period of non-use of the affected “paretic” limb can lead to further loss of… read more
New technology called called VirScan developed by Howard Hughes Medical Institute (HHMI) researchers makes it possible to test for current and past infections with any known human virus by analyzing a single drop of a person’s blood.
With VirScan, scientists can run a single test to determine which viruses have infected an individual, rather than limiting their analysis to particular viruses. That unbiased approach could uncover unexpected… read more

Researchers at the Georgia Institute of Technology have discovered an new process for assembling DNA nanostructures in a water-free solvent, which may allow for fabricating more complex nanoscale structures — especially, nanoelectronic chips based on DNA.
Scientists have been using DNA to construct sophisticated new structures from nanoparticles (such as a recent development at Brookhaven National Labs reported by KurzweilAI May 26), but the use… read more
