DeepMind, an artificial intelligence (AI) subsidiary of Google parent Alphabet, said it has been successful in predicting the shape of nearly every protein in the human body as well as thousands of other proteins found in 20 additional organisms that scientists rely on for their research, including yeast, fruit flies, and mice. This breakthrough is likely to assist researchers to understand human diseases better and find new drugs to treat or cure them. Some scientists have compared the DeepMind project to the international effort to map every human gene.

DeepMind said in a blog post it is releasing the database for free. To set up and run the database, it has partnered with the European Molecular Biology Laboratory. The database has already been made available in a searchable format.

The database comprises 350,000 newly predicted protein structures and the company said in the coming months it will release another 100 million protein structures to cover “almost every sequenced protein known to science.”

“This will be one of the most important datasets since the mapping of the Human Genome,” said Ewan Birney, European Molecular Biology Laboratory Deputy Director-General. However, more needs to be done. DeepMind’s software predicts protein structures, that means in some cases further experiments may be required to verify those predictions.

In December 2020, DeepMind surprised the world by solving a 50-year grand challenge with AlphaFold AI system. Proteins are made of long ribbons of amino acids, tied into complicated knots. Knowing the shape of a protein’s knot can reveal the function of the protein. This understanding is crucial to figuring out diseases and developing new drugs. Using AI, AlphaFold can predict a protein’s shape in a day or two, that would otherwise take weeks or months in the lab.

“As a powerful tool that supports the efforts of researchers, we believe this is the most significant contribution AI has made to advancing scientific knowledge to date and is a great example of the benefits AI can bring to humanity,” DeepMind said.

Fossils Reveal Evolution of Early Nervous Systems in Ecdysozoans

A discovery has shed light on the early evolution of nervous systems in ecdysozoan animals, a group that includes insects, nematodes, and priapulid worms. Fossil evidence from the early Cambrian Kuanchuanpu Formation has revealed details of the ventral nerve cord structure in ancient organisms, providing key insights into the evolutionary history of this critical component of the central nervous system. This discovery offers a glimpse into the nervous system architecture of one of the earliest known ecdysozoan lineages.

Revelations From Cambrian Fossils

According to a study titled Preservation and early evolution of scalidophoran ventral nerve cord published in Science Advances, scientists analysed fossils from Cambrian deposits, including those of Eopriapulites and Eokinorhynchus. As reported by phs.org, the findings suggest that the ancestors of scalidophorans, a subgroup of ecdysozoans, possessed a single ventral nerve cord. Researchers observed structures along the ventral side of these ancient organisms, resembling the ventral nerve cords of modern priapulid worms.

Dr. Deng Wang from Northwest University and Dr. Jean Vannier from Université de Lyon indicated to phys.org that these impressions represent early examples of the nervous system design seen in present-day ecdysozoans. This evidence supports the hypothesis that a single ventral nerve cord was the ancestral condition for this group.

Implications for Evolutionary Biology

The study has highlighted evolutionary connections between the structure of the ventral nerve cord and the segmentation of body plans in ecdysozoans. According to statement to phys.org by Dr. Chema Martin-Durán of Queen Mary University of London, the findings propose that the common ancestor of all ecdysozoans likely had a single ventral nerve cord. Changes leading to paired nerve cords, seen in arthropods and kinorhynchs, are believed to have evolved independently, reflecting adaptations to segmented body structures.

Dr. María Herranz from Rey Juan Carlos University suggested that the emergence of paired nerve cords may have enhanced locomotion and coordination in segmented animals during the Precambrian-Cambrian transition. These findings underscore the role of fossil studies in uncovering the complexities of early animal development.

Antarctica’s Pyramid-Shaped Peak: A Geological Masterpiece

Antarctica’s Pyramid-Shaped Peak: A Geological Masterpiece

A peak resembling a man-made pyramid, situated in the snow-covered expanse of Antarctica, has captured widespread attention due to its striking symmetry. Located within the southern Ellsworth Mountains, this natural formation features four steep, symmetrical faces, drawing comparisons to ancient Egyptian pyramids. Rising approximately 4,150 feet (1,265 meters), the mountain has become a focal point of speculation since it gained internet fame in 2016, with many questioning whether its shape could be the work of ancient civilizations or extraterrestrial beings.

Natural Formation Through Erosion

As reported by Live Science, the unique geometry of the mountain is attributed to natural erosion processes. Experts suggest that the peak was likely sculpted by freeze-thaw erosion over millions of years. Mauri Pelto, a professor of environmental science at Nichols College, explained to Live Science that during this process, water fills rock crevices during the day, freezes at night, and expands, causing chunks of rock to break off gradually. This slow but consistent erosion is believed to have given the mountain its distinct pyramidal shape. Pelto noted that while three of the mountain’s sides appear to have eroded evenly, the fourth side—the eastern ridge—formed separately.

Conspiracy Theories and Expert Opinions

Speculation about the mountain’s origin surged when its images circulated online. Claims involving forgotten civilizations or extraterrestrial construction have been widely shared by conspiracy theorists. However, Eric Rignot, professor of Earth system science at the University of California, Irvine, and senior research scientist at NASA’s Jet Propulsion Laboratory, dismissed these ideas while talking to Live Science. Rignot stated that pyramid-like shapes are not uncommon in nature, citing that peaks with one or two steep faces are often observed, though fully symmetrical formations are rare.

Historical and Geological Significance

First observed during a 1935 flight by American aviator Lincoln Ellsworth, the Ellsworth Mountains hold significant geological history, including 500-million-year-old fossils. The pyramid-shaped peak adds to the intrigue of this remote region but is regarded by scientists as a testament to nature’s sculpting power rather than evidence of advanced or extraterrestrial involvement.

Mark Your Calendars! The Next Blue Moon Arrives on May 31, 2026

A Blue Moon, a term often associated with rarity, will next occur on May 31, 2026. This event refers to the second full moon within a single calendar month, a phenomenon that arises due to the lunar cycle of approximately 29.5 days. Typically, 12 full moons are observed annually; however, the slight mismatch between the lunar cycle and the calendar year results in a 13th full moon approximately every two to three years, earning it the designation of a Blue Moon.

Types of Blue Moons Explained

As reported by NASA, there are two classifications of Blue Moons: seasonal and monthly. A seasonal Blue Moon is defined as the third full moon in a season containing four full moons, while a monthly Blue Moon occurs when two full moons appear within the same calendar month. The upcoming Blue Moon in May 2026 will be of the monthly variety.

Despite its name, the moon does not turn blue during this occurrence. The term has historical roots and is now widely accepted to describe these rare lunar events.

Historical Occurrences of Blue Moons

The last Blue Moon was recorded on August 19, 2024. Such events, while uncommon, are predictable and occur at intervals due to the alignment of lunar phases with the Gregorian calendar. The next seasonal Blue Moon is anticipated on August 21, 2032.

Can the Moon Actually Appear Blue?

Instances of the moon appearing blue are exceedingly rare and are attributed to atmospheric conditions rather than lunar phenomena. Volcanic eruptions, such as Krakatoa in 1883, and large-scale forest fires have caused atmospheric particles to scatter red light, giving the moon a bluish tint.
