Apollo’s last three missions were arguably the most scientifically significant, largely due to roving vehicles which the astronauts used to jaunt from point to point over the Moon’s extremely difficult terrain.
😀 This could to more complex organisms being resurrected.
Deep in the tissues of sea anemones, corals, and jellyfish are strange yellow cells which are genetically distinct from the marine animals.
More than a century after these cells were first assigned a now forgotten genus, a new paper has resurrected the name and described six new species from around the world.

U.S. Special Operations Command (SOCOM), the organization that administers America’s Spec Ops forces, says it will soon start clinical trials of an “anti-aging pill” that could halt some naturally degenerative effects of aging.
“We have completed pre-clinical safety and dosing studies in anticipation of follow-on performance testing in fiscal year 2022,” Navy Commander Tim Hawkins, a SOCOM spokesperson, told Breaking Defense.

An elegant new algorithm developed by Danish researchers can significantly reduce the resource consumption of the world’s computer servers. Computer servers are as taxing on the climate as global air traffic combined, thereby making the green transition in IT an urgent matter. The researchers, from the University of Copenhagen, expect major IT companies to deploy the algorithm immediately.
One of the flipsides of our runaway internet usage is its impact on climate due to the massive amount of electricity consumed by computer servers. Current CO2 emissions from data centers are as high as from global air traffic combined—with emissions expected to double within just a few years.
Only a handful of years have passed since Professor Mikkel Thorup was among a group of researchers behind an algorithm that addressed part of this problem by producing a groundbreaking recipe to streamline computer server workflows. Their work saved energy and resources. Tech giants including Vimeo and Google enthusiastically implemented the algorithm in their systems, with online video platform Vimeo reporting that the algorithm had reduced their bandwidth usage by a factor of eight.
But hey, at least all that money is going to charity.
You know that $5.43M NFT that contained files pertaining to the source code for the world wide web? The one created by Sir WWW Tim Berners-Lee himself? Turns out there’s a scripting error in the video representation of the source code. It has been highlighted by Mikko Hypponen, a researcher at F Secure, on Twitter who pointed out that “the angle brackets are wrong!” If you watch the start of the video visualisation of the code on the Sotheby’s auction page you can see that where there should be ‘’ characters they have been replaced by something else entirely.
Australian scientists will help construct one of the world’s most powerful ground-based telescopes that promises to see further and clearer than the Hubble Space Telescope and unlock mysteries of the early Universe.
The team will develop a new, world-first instrument that will produce images three times sharper than Hubble under the multimillion-dollar project.
The MAVIS instrument will be fitted to one of the eight-meter Unit Telescopes at the European Southern Observatory’s (ESO’s) Very Large Telescope in Chile, to remove blurring from telescope images caused by turbulence in Earth’s atmosphere. MAVIS will be built over seven years at a cost of $57 million.
Deposit contains exceptionally preserved fossils of soft-bodied, juvenile organisms from the Cambrian period.
All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international team of researchers.
The fossil deposit, called the Haiyan Lagerstätte, contains an exceptionally preserved trove of early vertebrates and other rare, soft-bodied organisms, more than 50% of which are in the larval and juvenile stages of development. Dating to the Cambrian geologic period approximately 518 million years ago and providing researchers with 2846 specimens so far, the deposit is the oldest and most diverse found to date.
The fossil fuel power plant that a private equity firm revived to mine bitcoin is at it again. Not content to just pollute the atmosphere in pursuit of a volatile crypto asset with little real-world utility, this experiment in free marketeering is also dumping tens of millions of gallons of hot water into glacial Seneca Lake in upstate New York.
“The lake is so warm you feel like you’re in a hot tub,” Abi Buddington, who lives near the Greenidge power plant, told NBC News.
An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn’s moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences & Lettres University.
Giant water plumes erupting from Enceladus have long fascinated scientists and the public alike, inspiring research and speculation about the vast ocean that is believed to be sandwiched between the moon’s rocky core and its icy shell. Flying through the plumes and sampling their chemical makeup, the Cassini spacecraft detected a relatively high concentration of certain molecules associated with hydrothermal vents on the bottom of Earth’s oceans, specifically dihydrogen, methane and carbon dioxide. The amount of methane found in the plumes was particularly unexpected.
“We wanted to know: Could Earthlike microbes that ‘eat’ the dihydrogen and produce methane explain the surprisingly large amount of methane detected by Cassini?” said Régis Ferrière, an associate professor in the University of Arizona Department of Ecology and Evolutionary Biology and one of the study’s two lead authors. “Searching for such microbes, known as methanogens, at Enceladus’ seafloor would require extremely challenging deep-dive missions that are not in sight for several decades.”
Most biological traits are inherited via genes, but there are exceptions to this rule. Two teams from the University of Geneva (UNIGE) have been investigating the location of centromeres—specific sites on chromosomes that are essential for cell division. They found that in the small worm Caenorhabiditis elegans, the transmission of the correct location of these sites to the offspring is not mediated by genes, but by an epigenetic memory mechanism. These results have been published in the journal PLOS Biology.
Living organisms, from humans to microscopic worms, inherit physical and sometimes behavioral traits from their parents. The transmission of biological traits is usually mediated by DNA which is replicated at each cell division and contains the genes. However, some characteristics can be transmitted from one generation to the next independently of genes: these are epigenetic phenomena.
