Computer simulations of the brain can predict language recovery in stroke survivors

Posted by in categories: biotech/medical, computing, neuroscience

At Boston University, a team of researchers is working to better understand how language and speech is processed in the brain, and how to best rehabilitate people who have lost their ability to communicate due to brain damage caused by a stroke, trauma, or another type of brain injury. This type of language loss is called aphasia, a long-term neurological disorder caused by damage to the part of the brain responsible for language production and processing that impacts over a million people in the US.

“It’s a huge problem,” says Swathi Kiran, director of BU’s Aphasia Research Lab, and College of Health & Rehabilitation Sciences: Sargent College associate dean for research and James and Cecilia Tse Ying Professor in Neurorehabilitation. “It’s something our lab is working to tackle at multiple levels.”

For the last decade, Kiran and her team have studied the brain to see how it changes as people’s improve with speech . More recently, they’ve developed new methods to predict a person’s ability to improve even before they start therapy. In a new paper published in Scientific Reports, Kiran and collaborators at BU and the University of Texas at Austin report they can predict recovery in Hispanic patients who speak both English and Spanish fluently—a group of aphasia patients particularly at risk of long-term language loss—using sophisticated computer models of the brain. They say the breakthrough could be a game changer for the field of speech therapy and for stroke survivors impacted by aphasia.

Leaked Nvidia cryptocurrency card could be powerful enough to save gaming GPUs from the mines

Posted by in categories: computing, cryptocurrencies

The Nvidia 170HX could offer an Ethereum hash rate way in excess of an RTX 3090 for less power.


The latest rumours point to a brand new Nvidia cryptocurrency mining processor that’s capable of an Ethereum mining hash rate 164MH/s. If you’re not familiar with the hash rates of cryptocurrency mining, that make it an absolute whopper of a card—the GeForce RTX 3090 is somewhere in the region of 120-130MH/s. Wild, right?

It’s called the 170HX, says Twitter leaker 9550Pro, and it will feature 4480 CUDA Cores and run at 250W. Its secret, how it manages to out mine a beefier card in the 350W RTX 3090, is the choice of memory. There’s just 8GB of it on the reported card but that 8GB is made up of HBM2e, the HBM in which literally stands for High Bandwidth Memory.

AMD says it’s up to Nvidia to optimize for FidelityFX Super Resolution

Posted by in category: computing

Despite FSR being open source and cross-vendor, collaboration is sorely lacking.


Following AMD’s announcements about its open source, cross-vendor upscaling technology, FidelityFX Super Resolution, Radeon’s vice president & general manager Scott Herkelman has reminded followers on Twitter that Nvidia will have to do its part to make the tech worthwhile on its GPUs.

Race on.

New internet woven from ‘spooky’ quantum links could supercharge science and commerce

Posted by in categories: computing, finance, internet, quantum physics, science

For that, they will need the quantum equivalent of optical repeaters, the components of today’s telecommunications networks that keep light signals strong across thousands of kilometers of optical fiber. Several teams have already demonstrated key elements of quantum repeaters and say they’re well on their way to building extended networks. “We’ve solved all the scientific problems,” says Mikhail Lukin, a physicist at Harvard University. “I’m extremely optimistic that on the scale of 5 to 10 years… we’ll have continental-scale network prototypes.”


Advance could precisely link telescopes, yield hypersecure banking and elections, and make quantum computing possible from anywhere.

Microsoft looks ready to launch Windows 11

Posted by in category: computing

Microsoft keeps hinting at a new version of Windows.


Microsoft has been teasing a “next generation” of Windows for months now, but new hints suggest the company isn’t just preparing an update to its existing Windows 10 software, but a new, numbered version of the operating system: Windows 11.

The software giant announced a new Windows event for June 24th yesterday, promising to show “what’s next for Windows.” The event invite included an image of what looks like a new Windows logo, with light shining through the window in only two vertical bars, creating an outline that looks very much like the number 11. Microsoft followed up with an animated version of this image, making it clear the company intentionally ignored the horizontal bars.

Neuralink Brain Chip Will End Language in Five to 10 Years, Elon Musk Says

Posted by in categories: computing, Elon Musk, neuroscience

In a recent interview, Elon Musk stated that the human language could possibly end within five to ten years. The CEO of Neuralink went to talk with Joe Rogan, implying that with the innovation of the brain chip the company is currently developing, humans won’t have to speak anymore using traditional languages.


Neuralink develops a chip that will soon be able to attach to the human brain. The chip’s invention aimed to communicate faster and conveniently. Through a single universal language, Elon Musk believes that the way we talk today will soon improve. The brain chip is expected to be completed to be developed within a few years, and by then, our communication could possibly evolve.

A Browsable Petascale Reconstruction of the Human Cortex

Posted by in categories: computing, mapping, neuroscience

In January 2020 we released the fly “hemibrain” connectome — an online database providing the morphological structure and synaptic connectivity of roughly half of the brain of a fruit fly (Drosophila melanogaster). This database and its supporting visualization has reframed the way that neural circuits are studied and understood in the fly brain. While the fruit fly brain is small enough to attain a relatively complete map using modern mapping techniques, the insights gained are, at best, only partially informative to understanding the most interesting object in neuroscience — the human brain.

Today, in collaboration with the Lichtman Laboratory at Harvard University, we are releasing the “H01” dataset, a 1.4 petabyte rendering of a small sample of human brain tissue, along with a companion paper, “A connectomic study of a petascale fragment of human cerebral cortex.” The H01 sample was imaged at 4nm-resolution by serial section electron microscopy, reconstructed and annotated by automated computational techniques, and analyzed for preliminary insights into the structure of the human cortex. The dataset comprises imaging data that covers roughly one cubic millimeter of brain tissue, and includes tens of thousands of reconstructed neurons, millions of neuron fragments, 130 million annotated synapses, 104 proofread cells, and many additional subcellular annotations and structures — all easily accessible with the Neuroglancer browser interface.
