'Periodic table of machine learning' could fuel AI discovery

Computers and Math from Science Daily Feed - Wed, 04/23/2025 - 10:50am
After uncovering a unifying algorithm that links more than 20 common machine-learning approaches, researchers organized them into a 'periodic table of machine learning' that can help scientists combine elements of different methods to improve algorithms or create new ones.

This Distant Exoplanet is Melting Away and Leaving a Comet-like Tail

Universe Today Feed - Wed, 04/23/2025 - 10:48am

If we need more evidence that our Solar System is not representative of other solar systems, take a look at BD+05 4868. It's a binary star consisting of a K-dwarf and an M-dwarf about 140 light-years away. It's not just the binary star sets the system apart from ours. A small rocky planet is so close to the primary star that it's being vaporized, leaving a trail of debris like a comet.

WEIT, now online in Arabic!

Why Evolution is True Feed - Wed, 04/23/2025 - 9:20am

I have long wished for my first trade book, Why Evolution is True, to be published in Arabic. That’s because many who adhere to Islam take the Qur’an literally (it’s almost a requirement) and the Qur’an is explicitly creationist, saying that Allah created the Universe in six days and that humans were created from a glob of mud.  I am unsure how often evolution is taught is universities or secondary schools in Islamic countries, but I at least wanted the evidence for evolution that I adduce in WEIT to be available to Arab-speakers.

The book was translated into Arabic by the Egyptian Translation Service, but their copyright has apparently run out, and at any rate, someone told me that the translation was now available free on the internet.

So, if you are in an Arab-speaking country, you can find the contents of WEIT here or by clicking on the title page below. You can also find the pdf here.

I was amused to see that when I translated the cover into English, it reads this way:

So be it, I am Dr. Quinn. Spread the word about this so that others can read the book, a book up to now available only in one small bookstore in Cairo, and only in a few copies (I have only one).  Certainly the original book in Arabic, as Rodney Dangerfield might say, “got no respect.”

Innovative approaches advance search for ice on the moon

Space and time from Science Daily Feed - Wed, 04/23/2025 - 8:26am
Scientists and space explorers have been on the hunt to determine where and how much ice is present on the Moon. Water ice would be an important resource at a future lunar base, as it could be used to support humans or be broken down to hydrogen and oxygen, key components of rocket fuel. Researchers are now using two innovative approaches to advance the search for ice on the Moon.

Current AI risks more alarming than apocalyptic future scenarios

Computers and Math from Science Daily Feed - Wed, 04/23/2025 - 8:21am
Most people generally are more concerned about the immediate risks of artificial intelligence than they are about a theoretical future in which AI threatens humanity. A new study reveals that respondents draw clear distinctions between abstract scenarios and specific tangible problems and particularly take the latter very seriously.

Some protective resin coatings may damage metal artifacts

Matter and energy from Science Daily Feed - Wed, 04/23/2025 - 8:20am
Conservators and museum technicians protect precious archaeological metal objects, such as tools and weapons, with clear coatings, leaving preserved and unobstructed views of these detailed treasures. However, researchers have reported that some of the resins used for these coatings react with iron-containing metals and can cause damage. The team developed a non-invasive fluorescence imaging strategy that reveals early signs of these damaging chemical reactions and confirmed its utility on ancient artifacts.

Scientists have found a way to 'tattoo' tardigrades

Matter and energy from Science Daily Feed - Wed, 04/23/2025 - 8:20am
If you haven't heard of a tardigrade before, prepare to be wowed. These clumsy, eight-legged creatures, nicknamed water bears, are about half a millimeter long and can survive practically anything: freezing temperatures, near starvation, high pressure, radiation exposure, outer space and more. Researchers took advantage of the tardigrade's nearly indestructible nature and gave the critters tiny 'tattoos' to test a microfabrication technique to build microscopic, biocompatible devices.
