I’ve Been Thinking by Daniel C Dennett review — an engaging, vexing memoir with a humility bypass

The veteran US philosopher renowned for his theories of consciousness is an intriguing figure but too prone to ‘professorial preening’.

To Defend the Genome, These Cells Destroy Their Own DNA

Posted by in category: biotech/medical

In a recent study, scientists stained the DNA of this worm hatchling to hunt down segments of DNA that they’d seen deleted from its genome earlier in development. The deleted fragments (red) survive only in germline cells in the worm’s gonads.

To figure out what was going on, Delattre’s lab looked at the DNA of an adult worm. The researchers compared the genomes of M. belari’s germline cells — the specialized reproductive cells like sperm and eggs — with the genomes of the worm’s somatic (nonreproductive) cells. The somatic genomes were missing long strings of sequences present in germline genomes. Sometime between the embryo’s growth from seven cells to 32, huge chunks of DNA had vanished.

The scientists then watched nematode embryos develop under a microscope. As the cells grew and replicated their genomes, they broke 20 chromosomes down into fragments and then reassembled them into 40 miniature chromosomes. Most of the fragments rejoined in this new, smaller genome — but a substantial fraction were left out.

How to Use ChatGPT’s New Image Features

Posted by in categories: mobile phones, robotics/AI

OpenAI recently announced an upgrade to ChatGPT (Apple, Android) that adds two features: AI voice options to hear the chatbot responding to your prompts, and image analysis capabilities. The image function is similar to what’s already available for free with Google’s Bard chatbot.

Even after hours of testing the limits and capabilities of ChatGPT, OpenAI’s chatbot still manages to surprise and scare me at the same time. Yes, I was quite impressed with the web browsing beta offered through ChatGPT Plus, but I remained anxious about the tool’s ramifications for people who write for money online, among many other concerns. The new image feature arriving for OpenAI’s subscribers left me with similarly mixed feelings.

While I’ve not yet had the opportunity to experiment with the new audio capabilities (other great reporters on staff have), I was able to test the soon-to-arrive image features. Here’s how to use the new image search coming to ChatGPT and some tips to help you start out.

NASA Begins Plans for $1 Billion Spacecraft to Safely Pull International Space Station Back To Earth

Posted by in categories: innovation, space

NASA has officially called upon companies to submit designs for a so-called U.S. Deorbit Vehicle (USDV) for the International Space Station (ISS). This pioneering spacecraft would have the crucial mission of safely bringing the ISS back to Earth, marking the ISS’s planned retirement.

The unprecedented project comes with an estimated price tag “a little short of about $1 billion,” as reported earlier this year by Kathy Lueders, NASA Associate Administrator for Space Operations.

Although initial considerations revolved around employing Russian spaceships for this monumental task, NASA, in a strategic shift, opened the floor this month to proposals from U.S. industry. The deadline for these innovative submissions is set for November 17, following the initiation of the call for designs on September 20.

Scientists just proved that ‘monster’ black hole M87 is spinning — confirming Einstein’s relativity yet again

Posted by in category: cosmology

Astronomers have found the first direct evidence of a black hole spinning, and it’s confirmed Einstein’s theory of relativity yet again.

The discovery was made by studying powerful jets of energy beamed from the solar system-size black hole at the center of the neighboring Messier 87 galaxy. The black hole, called M87, is the best studied black hole to date and the first to ever be directly imaged in 2019, with its “donut hole” shadow crowned by a fuzzy halo of light.

New Biosensors Allow Earbuds To Record Brain Activity and Exercise Levels

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

Who knows? Maybe this is a way for giving commands to a computer/AI instead of implants if further developed in the future.

The streaming data from these biosensors can be used for health monitoring and diagnosis of neuro-degenerative conditions.

A pair of earbuds can be turned into a tool to record the electrical activity of the brain as well as levels of lactate in the body with the addition of two flexible sensors screen-printed onto a stamp-like flexible surface.

Scientists developing implant to cure cancer in just 60 days — with goal to slash death rates by 50%

Posted by in categories: biotech/medical, health

That’s good news if it becomes successful! Cancer is such an awful disease.

There’ll be an app for that.

Curing cancer could soon be as easy as a few taps on your mobile, according to a team of scientists at Rice University who have received $45 million in funding for a novel, implant-based treatment system that could cut cancer death rates by 50%.

The Creation and Future of the Hydrogen Engine

Posted by in categories: sustainability, transportation

Automotive manufacturers, including Mazda and Toyota, are currently developing hydrogen engines to power their vehicles, and these engines could one day replace not only hydrogen fuel cell technology and traditional combustion engines, but perhaps even electric vehicles (EVs).
