Engineering team develops approach to enable simple cameras to see in 3D

Posted by in categories: mobile phones, robotics/AI, transportation

Standard image sensors, like the billion or so already installed in practically every smartphone in use today, capture light intensity and color. Relying on common, off-the-shelf sensor technology—known as CMOS—these cameras have grown smaller and more powerful by the year and now offer tens-of-megapixels resolution. But they’ve still seen in only two dimensions, capturing images that are flat, like a drawing—until now.

Researchers at Stanford University have created a new approach that allows standard image sensors to see in three dimensions. That is, these common cameras could soon be used to measure the distance to objects.

The engineering possibilities are dramatic. Measuring distance between objects with light is currently possible only with specialized and expensive —short for “light detection and ranging”—systems. If you’ve seen a self-driving car tooling around, you can spot it right off by the hunchback of technology mounted to the roof. Most of that gear is the car’s lidar crash-avoidance system, which uses lasers to determine distances between objects.

Scientists Create Synthetic Organisms That Can Reproduce

Posted by in categories: bioengineering, biological, information science

Scientists have created synthetic organisms that can self-replicate. Known as “Xenobots,” these tiny millimeter-wide biological machines now have the ability to reproduce — a striking leap forward in synthetic biology.

Published in the Proceedings of the National Academy of Sciences 0, a joint team from the University of Vermont, Tufts University, and Harvard University used Xenopus laevis frog embryonic cells to construct the Xenobots.

Their original work began in 2020 when the Xenobots were first “built.” The team designed an algorithm that assembled countless cells together to construct various biological machines, eventually settling on embryonic skin cells from frogs.

Is Aging Reversible? A Scientific Look with David Sinclair | David Sinclair | TEDxBoston

Posted by in categories: biotech/medical, genetics, life extension

NOTE FROM TED: Research around aging discussed in this talk remains an ongoing field of study. Please do not look to this talk for health advice. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf.

Have you ever wondered how long you will live? And if so, how could you change that number to live drastically longer? The science might be in your favor: follow David Sinclair, Australian biologist and professor of genetics at Harvard University, as he shares his research on slowing and reversing the process of aging in mice, and how the same technology may someday be transferable to humans. David Sinclair, Australian biologist and professor of genetics at Harvard Universityhis insightful research into the science of age reversal and anti-aging medicine.

Briefcase Computer Is A Glorious Cyberpunk Build

Posted by in category: computing

There are plenty of gaming laptops on the market these days, but none quite fit the requirements of one [ParticularlyPippin]. Thus, they set out on building their own portable computer, ending up with a rig in a briefcase with a decidedly cyberpunk feel.

The design relies on desktop components, with the idea being to make a machine with better upgradability than a typical laptop. The briefcase itself is a nice deep-shell unit, and was given a wooden baseboard to hold all the components. It was then provided with standoffs and mountings for a Mini-ITX motherboard, as well as all the necessary add-ons like fans and storage. As in many odd-form-factor builds, a PCI-E riser cable comes in handy to hook up the GPU.

As for the user interface, a USB portable monitor is paired with a mechanical keyboard for the appropriate amount of clackity-clack when hacking out in the field. The icing on the cake, however, are the RGB strip backlights controlled via MSI’s software that really make the final result pop.

New algorithm could be quantum leap in search for gravitational waves

Posted by in categories: computing, information science, quantum physics

A new method of identifying gravitational wave signals using quantum computing could provide a valuable new tool for future astrophysicists.

A team from the University of Glasgow’s School of Physics & Astronomy have developed a to drastically cut down the time it takes to match gravitational wave signals against a vast databank of templates.

This process, known as matched filtering, is part of the methodology that underpins some of the gravitational wave signal discoveries from detectors like the Laser Interferometer Gravitational Observatory (LIGO) in America and Virgo in Italy.

Large-scale neural recordings with single neuron resolution using Neuropixels probes in human cortex

Posted by in category: neuroscience

Recent advances in multi-electrode array technology have made it possible to monitor large neuronal ensembles at cellular resolution in animal models. In humans, however, current approaches restrict recordings to a few neurons per penetrating electrode or combine the signals of thousands of neurons in local field potential (LFP) recordings. Here we describe a new probe variant and set of techniques that enable simultaneous recording from over 200 well-isolated cortical singl… See more.


Neuropixels probes were used to simultaneously record from more than 200 cortical neurons in human participants during neurosurgical procedures. The approach could reveal insights underlying human cognition and pathology.
