I Edited Human DNA at Home With a DIY CRISPR Kit

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

I never thought Iโ€™d order live human kidney cells to my address, but that all changed when I found out about biohacker Jo Zaynerโ€™s at-home genetic engineering class.

You may know Jo Zayner, a โ€œbiohackerโ€ who has been in the vanguard of scientific self-experimentation for years, from their role in Netflixโ€™s 2019 docuseries Unnatural Selection. The series shows Zayner attempting to edit their DNA by injecting themselves with CRISPR, a gene-editing technology. The action inspired a firestorm of criticism.

Zayner is also known for a variety of other bold moves, such as claiming to create a DIY at-home COVID vaccine in 2020 and executing their own fecal microbiome transplant.

Elon Musk kills hope of Tesla retrofitting new Autopilot/Self-Driving hardware

Posted by in categories: Elon Musk, robotics/AI, transportation

Elon Musk has killed the little hope some had for Tesla in offering a retrofit to the new Autopilot/Self-Driving hardware (HW4) to current Tesla owners.

Tesla is expected to announce a new Autopilot/Self-Driving hardware suite, which has been referred to as Hardware 4.0 (HW4), any day now.

There have been quite a few indications that some major changes are coming. For example, after famously removing radar sensors from its hardware suite, we learned in December that Tesla is planning to add one as soon as this month.

Humans Have Degraded More Than A Third Of The Amazon Rainforest, Researchers Say

Posted by in category: futurism

More than one-third of the Amazon rainforest has been degraded by humans, according to a study published Thursday in the journal Science.

Degradation is different from deforestation, the researchers note, as it represents long-term changes in forest conditions that damages its ecosystem and results in carbon emissions greater to those from deforestation.


New estimates are larger than what scientists previously believed.

Google created an AI that can generate music from text descriptions, but wonโ€™t release it

Posted by in categories: media & arts, robotics/AI

An impressive new AI system from Google can generate music in any genre given a text description. But the company, fearing the risks, has no immediate plans to release it.

Called MusicLM, Googleโ€™s certainly isnโ€™t the first generative AI system for song. There have been other attempts, including Riffusion, an AI that composes music by visualizing it, as well as Dance Diffusion, Googleโ€™s own AudioML and OpenAIโ€™s Jukebox. But owing to technical limitations and limited training data, none have been able to produce songs particularly complex in composition or high-fidelity.

MusicLM is perhaps the first that can.

Chrome for Android now lets you lock your incognito session

Posted by in categories: privacy, robotics/AI, security

Chrome is rolling out an update for Android users that lets them lock their incognito sessions with a password code or biometric info when they exit the app. The feature has been available for iOS users for some time, but now itโ€™s being made available to folks using Chrome on Android.

Users can activate this feature by going to Chrome Settings Privacy & Security and turning on the โ€œLock incognito tabs when you close Chromeโ€ toggle. So next time when a user exits Chrome, their incognito session will automatically be locked. To unlock the incognito tabs, you can use the biometric unlock on the phone such as a fingerprint unlock or lock code.

Daniel C. Dennett โ€” What is Consciousness?

Posted by in category: neuroscience

Consciousness is what we can know best and explain least. It is the inner subjective experience of what it feels like to see red or smell garlic or hear Beethoven. Consciousness has intrigued and baffled philosophers. To begin, we must define and describe consciousness. What to include in a complete definition and description of consciousness?

Scientists Make Star Trek Technology Real With A Working Tractor Beam

Posted by in categories: nanotechnology, particle physics, tractor beam

Scientists how now developed a mini tractor beam that can pull atoms and nanoparticles. Scientists have built a real working tractor beam, albeit at a very small scale. The device, which attracts one object to another from a distance, originates in fiction. The term was coined by E. E. Smith who mentioned the technology in his 1931 novel Spacehounds of IPC, and since the 1990s, researchers have worked to make it a reality.

Scientists Made A Robot With Organic Muscles

Posted by in category: robotics/AI

Scientists have created skin for an organic robot that reacts to light and tightens when the robot walks. If you have seen any science fiction movies in your life, the term โ€œorganic robotโ€ surely fills you with a mixture of curiosity and alarm (if not outright terror).
