Could one of Earthโs most intelligent species be an alien, โseededโ on the planet by an interstellar genetic code? Scientists speculate that the clue might be found in the ancient precursor to life: RNA.

Yale SEAS teams with the Medical School to deliver a faster, more capable brain-implanted device to treat multiple disorders.
Linking brains to computers: how new implants are helping us achieve this goal
Researchers have developed implants small enough to fit inside brain cells.
Brain device records activity in record-breaking detail
Beyond that, the ECoG technology could be developed for use in the emerging field of brain-computer interfaces, which have a huge range of potential applications โ from controlling a computer just by thinking, to streaming music directly to your brain.
By uncovering new knowledge about how the brain works, for example, the device could be used to interpret hand motions in new ways utilising brain wave patterns.
2022: The Year in which Virtual Reality goes Mainstream
The Future of Virtual Reality has been shown at CES 2022 in the form of retina display VR Headsets, full body tracking solutions and brain computer interfaces previewing what the future of full dive virtual reality could look like. Companies such as Meta/Facebook, Google, Apple and Valve are all investing millions into making Virtual Reality mainstream and look just like real life.

Elon Musk nears human testing of brain chip
I wonder if you could use this stuff for brain scans.
Neuralink, the US neurotechnology firm co-founded by billionaire entrepreneur Elon Musk, has begun recruiting key employees to run its clinical trials, signaling that itโs inching closer to starting human testing of its brain implants.
The company has posted advertisements to hire a clinical trial director and a clinical trial coordinator. The ads note that the staffers will โwork closely with some of the most innovative doctors and top engineers, as well as working with Neuralinkโs first clinical trial participants.โ Neuralink said the director will lead and help build its clinical research team and will develop โregulatory interactions that come with a fast-paced and ever-evolving environment.โ
Musk, who ranks as the worldโs richest person with a fortune estimated at $256 billion, said last month that he expects to have Neuralink brain chips implanted in humans sometime in 2022, pending approval for testing plans by the US Food and Drug Administration (FDA).
Kernel Flow: A wearable device for noninvasive optical brain imaging
Recent advances in brain imaging techniques facilitate accurate, high-resolution observations of the brain and its functions. For example, functional near-infrared spectroscopy (fNIRS) is a widely used noninvasive imaging technique that employs near-infrared light (wavelength 700 nm) to determine the relative concentration of hemoglobin in the brain, via differences in the light absorption patterns of hemoglobin.
Most noninvasive brain scanning systems use continuous-wave fNIRS, where the tissue is irradiated by a constant stream of photons. However, these systems cannot differentiate between scattered and absorbed photons. A recent advancement to this technique is time-domain (TD)-fNIRS, which uses picosecond pulses of light and fast detectors to estimate photon scattering and absorption in tissues. However, such systems are expensive and complex and have a large form factor, limiting their widespread adoption.
To overcome these challenges, researchers from Kernel, a neurotechnology company, have developed a wearable headset based on TD-fNIRS technology. This device, called โKernel Flow,โ weighs 2.05 kg and contains 52 modules arranged in four plates that fit on either side of the head. The specifications and performance of the Kernel Flow system are reported in the Journal of Biomedical Optics (JBO).
Reinterpreting Our Brainโs Body Maps
Summary: The body relies on multiple maps based on the choice of the motor system.
Source: Tohoku University.
Our brain maps out our body to facilitate accurate motor control; disorders of this body map result in motor deficits. For a century, the body map has been thought to have applied to all types of motor actions. Yet scientists have begun to query how the body map operates when executing different motor actions, such as moving your eyes and hands together.
