In 2020 I joined the private beta test of Open AI’s Generative Pre-trained Transformer 3 (GPT-3), which is an earlier version of ChatGPT. When ChatGPT was released in November 2022, I started experimenting with it. For over two years I’ve been exploring the strengths and limits of this technology and assessing how this tool could be useful to me. I’m also interested how this new technology is being utilized by scientists and academics to make meaningful contributions to academic work and education.

A recent study demonstrated that ChatGPT was able to pass the US Medical Licensing Exam without any special training prior to the exam and was able to demonstrate a high level of insight in its explanations. The results suggest that ChatGPT may be able to assist with medical education.

I published the first article about my experiments with ChatGPT last week. The article entitled How The Evolution Of AI In Healthcare Aligns With Thomas Kuhn’s Structure has been viewed over 13,000 times, and has received and

In a study that raises profound questions about the line between life and death, researchers have restored some cellular activity to brains removed from slaughtered pigs.

The brains did not regain anything resembling consciousness: There were no signs indicating coordinated electrical signaling, necessary for higher functions like awareness and intelligence.

But in an experimental treatment, blood vessels in the pigs’ brains began functioning, flowing with a blood substitute, and certain brain cells regained metabolic activity, even responding to drugs. When the researchers tested slices of treated brain tissue, they discovered electrical activity in some neurons.

The San Jose, Calif.-based company on Thursday announced plans for the new regional headquarters in Frisco.

McAfee will open offices at The Star development, where the Dallas Cowboys are headquartered, by the middle part of this year, according to a release from Frisco city officials.

“Our decision to choose Frisco for our regional HQ was also based on the diverse cultural destination the city has become, and the many opportunities our team members will have to be immersed in the community and to give back to the many non-profit organizations here,” Benni Bueckert, a McAfee vice president, said in the release.

Basically many have theorized that these seeds coming from meteorites mean that essentially perhaps that life started from seeds like this. Going much deeper down the rabbit hole we actually are starting to see a grand design possibly by actually organisms that evolved into what we have now over millions of years which is actually weird because all earth would have been just a rock but this could be a grand architecture genetically even from the first seed to the biological singularity. This could Basically prove the existence of some entity that may have created humans and all life most like from this seed which means whether it is alien gods or God there will be so much more discover due to this complexity which can benefit all medicine and also genetic engineering 🤔 😉 😀

The fact the first of four surviving pieces was collected within 12 hours of landing, allowing little time for contamination, added to the meteorite’s value. Indeed, because the abundance of organic material in the meteorite was ten times lower than in other carbonaceous chondrites, they might not have been distinguishable from Earthly contamination had it not been retrieved so quickly. As it is, some of the amino acids found are quite rare on Earth, confirming their extraterrestrial origins.

The Winchcombe stones had a number of features never previously seen in meteorites, including low amino acid abundance for a carbonaceous chondrite but unusual ratios among the amino acids and PAHs that are present. Combined with the incomplete conversion of Winchcombe’s components into solid rock, this led the authors to speculate Winchcombe could represent a new class of meteorite that has not been studied before.

Perhaps in part because of its weak structure, very little of the Winchcombe meteorite made it to the ground. Just 600 grams (1.3 pounds) have been recovered, compared to a 27-kilogram (60-pound) carbonaceous chondrite that landed in Costa Rica in 2019. This prevented certain forms of analysis that require bulk samples.

There’s still nothing quite like thumbing the pages of a real-life print magazine, but the latest evolution of E Ink’s color tech is creeping tantalizingly close — at least as far as my eyes are concerned.

You’ve heard it all before: A lifetime of staring at screens has worn out my eyes, leading me down a rabbit hole of lifehacky solutions to ease the fatigue. Some of the tricks I picked up over the years have helped — especially the one where I simply take breaks and go for walks — but one thing hasn’t changed: I still spend more time than I’d like gazing at glossy displays.

I don’t want anything less for videos or gaming, but for reading I typically ignore the latest tech and instead turn to a 2016 Kindle Oasis or old-fashioned books. My hands can obviously tell the difference between the two, but when I’m lost in a story, I don’t think my eyes can. With paper and e-paper alike, a sense of ease washes over me as I read. Is it how the light bounces off the page? Or, is it because I know ads and notifications won’t bombard me at every turn? I’m not sure, and I don’t really care why; I just prefer it, and E Ink reminded me of that when I stepped into its little conference room last week in Las Vegas.

It took two years to gather all the data included in this image.

This detailed catalog of the stars in our galaxy was a challenge to produce. The telescope’s near-infrared camera helped astronomers see through the clouds of dust that weave their way between the stars, blocking shorter wavelengths of light like visible and ultraviolet. But sometimes the problem is too much light. Our galaxy’s disk is packed so full of stars that they often overlap when you try to photograph them all, and the diffuse light from nebulae and star clusters makes it even harder to single out individual stars. Saydjari and his colleagues used a data processing program that helped predict the background behind each star, making it easier to separate one star from another.

“One of the main reasons for the success of DECaPS2 (the Dark Energy Camera Plane Survey’s second data release) is that we simply pointed at a region with an extraordinarily high density of stars and were careful about identifying sources that appear nearly on top of each other,” says Saydjari.

I posted about Japan releasing radioactive water, and thought it was a bad idea, because of this MIT revelation.

Nuclear power continues to expand globally, propelled, in part, by the fact that it produces few greenhouse gas emissions while providing steady power output. But along with that expansion comes an increased need for dealing with the large volumes of water used for cooling these plants, which becomes contaminated with radioactive isotopes that require special long-term disposal.

Now, a method developed at MIT provides a way of substantially reducing the volume of contaminated water that needs to be disposed of, instead concentrating the contaminants and allowing the rest of the water to be recycled through the plant’s cooling system. The proposed system is described in the journal Environmental Science and Technology, in a paper by graduate student Mohammad Alkhadra, professor of chemical engineering Martin Bazant, and three others.

The method makes use of a process called shock electrodialysis, which uses an electric field to generate a deionization shockwave in the water. The shockwave pushes the electrically charged particles, or ions, to one side of a tube filled with charged porous material, so that concentrated stream of contaminants can be separated out from the rest of the water. The group discovered that two radionuclide contaminants — isotopes of cobalt and cesium — can be selectively removed from water that also contains boric acid and lithium. After the water stream is cleansed of its cobalt and cesium contaminants, it can be reused in the reactor.

Elon Musk said the private space firm has “a real shot at late February” for the orbital launch of Starship.

We might finally see SpaceX’s Starship soar to orbit next month. SpaceX’s orbital launch of its fully reusable Starship rocket is arguably the most exciting upcoming space mission of the year. And we may not have to wait very long to see it take to the skies.

Starship could fly to orbit for the first time as soon as late February, though March is more likely, according to an update from SpaceX CEO Elon Musk via Twitter.

People suffering from schizophrenia can expect to die 15 years sooner than they ordinarily would. A new study has now found that this could be partly caused by advanced brain aging. The research findings were published in the journal Molecular Psychiatry.

Schizophrenia is associated with an increased risk of premature death, partially as a result of suicide or poor physical health. Studies to date have suggested that the high prevalence of disease, long-term and excess deaths in people with schizophrenia could in part be caused when their brain’s biological age overtakes the .

According to a few small-scale studies, this discrepancy called brain-predicted age difference (brain-PAD) has been found to be consistently higher in schizophrenic patients compared to healthy individuals. The studies have also shown that the gap between the two ages mainly widens during the first years after the onset of the illness.
