Bluetooth-enabled device warns if body rejects a new organ

Posted by in category: biotech/medical

The device is the size of a fingernail, is Bluetooth-enabled, and has a coin battery.

After an organ transplant, the body either accepts the organ or rejects it. All patients have some amount of acute rejection, but hyperacute rejection is when the body vehemently rejects the organ and it must be removed immediately to save the life of the patient. And then there’s chronic rejection, which can take many years as the body’s immune response towards the new organ slowly damages the transplanted tissues or organ.

So, how do we detect early on that an organ transplant has failed? The gold standard is currently via a biopsy, performed periodically to detect rejection early before symptoms develop.

NASA’s MOXIE wraps mission with breath of fresh Martian air

Posted by in categories: futurism, space

Since the Perseverance rover’s landing in 2021, MOXIE has produced a cumulative 122 grams of oxygen.

NASA’s Mars Oxygen In-Situ Resource Utilization Experiment (MOXIE) successfully concluded its mission by producing oxygen on the Red Planet for the 16th and final time. Developed by a team at the Massachusetts Institute of Technology (MIT), the machine exceeded the initial expectations of its creators and has set a strong precedent for future missions aimed at human exploration of Mars.

“MOXIE’s outstanding results validate the viability of extracting oxygen from the Martian atmosphere—a crucial resource for both life-support and propellant for return missions,” stated NASA Deputy Administrator… More.

New details of Musk’s involvement in the Ukraine-Russia war revealed in his biography.

Elon Musk holds many titles. He is the CEO of Tesla SpaceX and owns the social media company X, which was recently rebranded from Twitter. Going by an excerpt of his biography, published in the Washington Post.

According to the excerpt from Walter Isaacson’s book, Musk disabled his company Starlink’s satellite communication networks, which were being used by the Ukrainian military to attack the Russian naval fleet in Sevastopol, Crimea, sneakily. The Ukrainian army was using Starlink as a guide to target Russian ships and attack them with six small… More.

Math Reveals Secrets of Synchronization in Complex Systems

Posted by in categories: mathematics, neuroscience

Summary: Researchers delved deep into the mysteries of synchronization in complex systems, uncovering how certain elements effortlessly fall into or out of sync. This dance of coordination can be observed from humans clapping in rhythm to the synchronicity of heart cells.

By studying “walks” through networks, the team discovered the role of convergent walks in diminishing the quality of synchronization. These findings could revolutionize our understanding of everything from power grid stability to brain functions and social media dynamics.

Asteroid behaving weirdly after NASA crash

Posted by in categories: asteroid/comet impacts, existential risks

The mission was successful, and Dimorphos’ orbit was shortened by 33 minutes in the weeks after the impact.

However, a team of high school students led by teacher Jonathan Swift at Thacher School in California have discovered that Dimorphos’ orbit continued to shrink by another minute more than a month after the collision.

‘The number we got was slightly larger, a change of 34 minutes,’ said Mr Swift. ‘That was inconsistent at an uncomfortable level.’

Sequential Memory Is A Unique Human Trait

Posted by in category: neuroscience

Summary: New research unveils a probable unique human ability to recognize and remember sequential information. Despite being our closest relatives, bonobos struggle to learn the order of stimuli in the same manner as humans.

This discovery contributes to understanding the cognitive distinctions between humans and other animals, explaining why only humans possess certain cultural abilities like language and advanced planning. This sequential memory might be the foundational block behind many uniquely human behaviors and capabilities.

WiMi Developed Metasurface Eyepiece for Augmented Reality with Ultra-wide FOV

Metalens for AR and VR.


BEIJING, Sept. 8, 2023 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WIMI) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced that a metasurface eyepiece for augmented reality has been developed, which is based on metasurfaces composed of artificially fabricated subwavelength structures. The metasurface eyepiece employs a special optical design and engineered anisotropic optical response to achieve an ultra-wide field of view(FOV), full-color imaging, and high-resolution near-eye display.

At the heart of the WiMi’s metalens are see-through metalens with a high numerical aperture(NA), a large area and broadband characteristics. Its anisotropic optical response allows it to perform two different optical functions simultaneously. First, it can image virtual information, acting as an imaging lens for virtual information. Second, it can transmit light, serving as a transparent glass for viewing a real-world scene. This design allows the transparent metalens to be placed directly in front of the eye without the need for additional optics, resulting in a wider FOV.

Fabrication of metalens is done using nanoimprinting technology, which is capable of fabricating large-area metalens with sub-wavelength structures. First, a mould or template with the desired structure is prepared. Then, the mould or template is contacted with a transparent substrate and the nanoscale structure is transferred by applying pressure and temperature. Through this nanoimprinting process, the subwavelength structure of the metalens is successfully replicated onto the transparent substrate, resulting in the formation of the metalens.
