Hawking radiation is not produced at the black hole horizon

Posted by in category: cosmology

Stephen Hawking’s “Brief History of Time” was one of the first popular science books I read, and I hated it. I hated it because I didn’t understand it. My frustration with this book is a big part of the reason I’m a physicist today – at least I know who to blame.

Light-Bending Microchip Could Fire Up Quantum Computers

Posted by in categories: computing, quantum physics, time travel

For the first time, scientists have achieved infinite speeds on a microchip. Although this advance will not enable faster-than-light starships, the light-warping technology behind this innovation could lead to new light-based microchips and help enable powerful quantum computers, researchers said.

Light travels at the speed of about 670 million miles per hour (1.08 billion km/h) in a vacuum, and is theoretically the fastest possible speed at which matter or energy can travel. Exceeding this speed limit should lead to impossible results such as time travel, according to Einstein’s theory of relativity.

However, in a way, researchers have overcome this barrier for decades. [Warped Physics: 10 Effects of Faster-Than-Light Travel].

SpaceX Will Attempt Next Rocket Landing At Cape Canaveral Instead Of In The Ocean

Posted by in category: space travel

Next time a SpaceX rocket touches down, it will be on solid ground.

Florida Today broke the news today that SpaceX was hoping to land its next Falcon 9 rocket on the ground at NASA’s Cape Canaveral facility in Florida.

SpaceX has attempted to land a rocket gently before, but those attempts were made on giant floating platforms in the ocean (which just missed). Then, last week, competitor Blue Origin managed to land it’s own reusable rocket safely on the ground, amping up the public pressure on SpaceX to successfully land their own rocket.

New AI ‘Gabriel’ wants to whisper instructions in your ear

Posted by in categories: biotech/medical, neuroscience, robotics/AI

Researchers at Carnegie Mellon University are building an AI platform that will “whisper” instructions in your ear to provide cognitive assistance. Named after Gabriel, the biblical messenger of God, the whispering robo-assistant can already guide you through the process of building a basic Lego object. But, the ultimate goal is to provide wearable cognitive assistance to millions of people who live with Alzheimer’s, brain injuries or other neurodegenerative conditions. For instance, if a patient forgets the name of a relative, Gabriel could whisper the name in their ear. It could also be programmed to help patients through everyday tasks that will decrease their dependence on caregivers.

For the software to exist as a working wearable assistant, it will need a head-mounted device to latch onto. For now, the team is using Google Glass for demos like a ping pong assistant, where the programs tells the user to hit the ball to the right or left depending on the position of the ball in relation to the opponent. In the video below, when the user follows the guidance it makes it harder for the opponent to defend the ball in the game.

Biologists induce flatworms to grow heads and brains of other species

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

Tufts biologists induced one species of flatworm —- G. dorotocephala, top left — to grow heads and brains characteristic of other species of flatworm, top row, without altering genomic sequence. Examples of the outcomes can be seen in the bottom row of the image. (credit: Center for Regenerative and Developmental Biology, School of Arts and Sciences, Tufts University.)

Tufts University biologists have electrically modified flatworms to grow heads and brains characteristic of another species of flatworm — without altering their genomic sequence. This suggests bioelectrical networks as a new kind of epigenetics (information existing outside of a genomic sequence) to determine large-scale anatomy.

Besides the overall shape of the head, the changes included the shape of the brain and the distribution of the worm’s adult stem cells.

Thanksgiving 2025: Technology Will Redefine What ‘Togetherness’ Is All About

Posted by in categories: mobile phones, robotics/AI

This might be a controversial post.

My Thanksgiving was one filled with texting, Snapchat, Skyping, Facetime, Beam robots and ringing phones.

Some people HATE the way technology impacts their family at gatherings — people on digital devices rather than having conversations — “making us more alone, even when we’re together.” But is that really true?

Researchers demonstrate world’s first 5G, 100 to 200 meter communication link up to 2 Gbps

Posted by in categories: computing, internet

Keysight Technologies, Inc., in collaboration with electrical engineers at the University of California, San Diego, has demonstrated the world’s first 64 (8 × 8) and 256-element (16 × 16), 60-GHz silicon wafer-scale phased-array transmitter with integrated high-efficiency antennas for Gbps communications at 100 to 200 meters. With this demonstration, Keysight and UC San Diego have proven that a 5G communication link is not only possible, but can deliver record performance.

Keysight’s collaboration with UC San Diego builds on an earlier effort between the university and TowerJazz, which resulted in development of the industry’s first 64- and 256-element system-on-a chip (SoC) phased arrays operating at 60-GHz. Each wafer-scale SoC comprises a 60-GHz source, amplifiers, , phase shifters, voltage controlled amplifiers and high-efficiency on-chip antennas. The chips were designed to meet the needs of 5G high-performance Gbps data-rate communication systems with beamforming capabilities and for Aerospace & Defense systems.

Following the development of the phased-array SoCs, Keysight and UC San Diego set out to prove they could be used in a communications link. All work was sponsored by the Defense Advanced Research Projects Agency (DARPA) and Keysight.
