May 2025 full moon is a flower moon and micromoon. Here's when to see it.
Micromoons look a bit smaller and dimmer than usual. They occur when a full moon coincides with the point in its orbit when it's farthest from Earth, known as apogee. As a result, the micromoon will appear about 14% smaller and 30% dimmer than usual.
Even so, May's moon will appear full to our eyes starting Sunday night May 11 through early Tuesday, May 13.
The full flower moon will reach peak illumination at 12:56 p.m. on May 12, 2025, according to the Old Farmer's Almanac. The moon will also appear bright and full on Sunday (May 11) and Tuesday (May 13).
To catch a glimpse, find a location with unobstructed views of the horizon.
During spring, flowers start to bloom across North America, inspiring the name of May's full moon, according to the almanac.
The almanac said full moon names "come from a number of places, including Native American, Colonial American, and European sources." The 'flower moon' name has been attributed to the Algonquin people.
The next full moon will be the strawberry moon, which appears on Wednesday, June 11, 2025.
Here are the rest of the full moons for 2025:
June 11: Strawberry Moon
July 10: Buck Moon
Aug. 9: Sturgeon Moon
Sept. 7: Harvest Moon
Oct. 6: Hunter's Moon
Nov. 5: Beaver Moon
Dec. 4: Cold Moon

Using AI Made Doctors Worse at Spotting Cancer Without Assistance
Credit - Getty Images Health practitioners, companies, and others have for years hailed the potential benefits of AI in medicine, from improving medical imaging to outperforming doctors at diagnostic assessments. The transformative technology has even been predicted by AI enthusiasts to one day help find a 'cure to cancer.' But a new study has found that doctors who regularly used AI actually became less skilled within months. The study, which was published on Wednesday in the Lancet Gastroenterology and Hepatology journal, found that over the course of six months, clinicians became over-reliant on AI recommendations and became themselves 'less motivated, less focused, and less responsible when making cognitive decisions without AI assistance.' It's the latest study to demonstrate potential adverse outcomes on AI users. An earlier study by the Massachusetts Institute of Technology found that ChatGPT eroded critical thinking skills. How the study was conducted Researchers across various European institutions conducted an observational study surveying four endoscopy centers in Poland that participated in the Artificial Intelligence in Colonoscopy for Cancer Prevention (ACCEPT) trial. The study was funded by the European Commission and Japan Society for the Promotion of Science. As part of the trial, the centers had introduced AI tools for the detection of polyps—growths that can be benign or cancerous—in late 2021. The study looked at 1,443 non-AI-assisted colonoscopies out of a total 2,177 colonoscopies conducted between September 2021 and March 2022. The colonoscopies were performed by 19 experienced endoscopists. Researchers compared the quality of colonoscopy conducted three months before and three months after AI was implemented. Colonoscopies were conducted either with or without AI assistance, at random. Of those conducted without AI assistance, 795 were conducted before regular AI use was implemented and 648 were conducted after the AI tools were introduced. What the study found Three months before AI was introduced, the adenoma detection rate (ADR) was around 28%. Three months after AI was introduced, the rate dropped to 22% when clinicians were unassisted by AI. ADR is a commonly used quality indicator for colonoscopies and represents 'the proportion of screening colonoscopies performed by a physician that detect at least one histologically confirmed colorectal adenoma or adenocarcinoma.' Adenomas are precancerous growths, and a higher ADR is associated with a lower risk of colorectal cancer. The study found that AI did help endoscopists with detection when used, but once the assistance was removed, clinicians were worse at detection. Researchers attributed it to 'the natural human tendency to over-rely' on the recommendations of decision support systems like AI. 'Imagine that you want to travel anywhere, and you're unable to use Google Maps,' Marcin Romańczyk, co-author of the study and an assistant professor at the Medical University of Silesia, told MedPage Today. 'We call it the Google Maps effect. We try to get somewhere, and it's impossible to use a regular map. It works very similarly.' Implications of the study Omer Ahmad, a consultant gastroenterologist at University College Hospital London who wrote an editorial alongside the study but was not involved in its research, tells TIME that it's likely that exposure to AI weakened doctors' visual search habits and alerting gaze patterns, which are critical for detecting polyps. 'In essence, dependence on AI detection could dull human pattern recognition,' Ahmad says. He adds that regular use of AI could also 'reduce diagnostic confidence' when AI assistance is withdrawn, or that the endoscopists' skill of manoeuvring the colonoscope could be reduced. In comments to the Science Media Center (SMC), Catherine Menon, principal lecturer at the University of Hertfordshire's Department of Computer Science, said: 'Although de-skilling resulting from AI use has been raised as a theoretical risk in previous studies, this study is the first to present real-world data that might potentially indicate de-skilling arising from the use of AI in diagnostic colonoscopies.' Menon raised concerns that overreliance on AI could leave health practitioners at risk to technological compromise. Other experts are more cautious about drawing conclusions from a single study. Venet Osmani, a professor of clinical AI and machine learning at Queen Mary University of London, noted to SMC that the total number of colonoscopies—including both AI-assisted and non-AI-assisted ones—increased over the course of the study. The increased workload, Osmani suggested, could have led to clinician fatigue and poorer detection rates. Allan Tucker, a professor of artificial intelligence at Brunel University of London, also noted that with AI assistance, clinician performance improved overall. Concerns about deskilling due to automation bias, added Tucker to SMC, 'is not unique to AI systems and is a risk with the introduction of any new technology.' 'The ethical question then is whether we trust AI over humans,' said Tucker. 'Often, we expect there to be a human overseeing all AI decision-making but if the human experts are putting less effort into their own decisions as a result of introducing AI systems this could be problematic.' 'This is not simply about monitoring technology,' says Ahmad. 'It's about navigating the complexities of a new human-AI clinical ecosystem.' Establishing safeguards is critical, he adds, suggesting that beyond this study, people may need to focus on 'preserving essential skills in a world where AI becomes ubiquitous.'

September 2025: Science History from 50, 100 and 150 Years Ago
1975 Earth Fires Seeds into Space 'Imagine that the earth has been watched over the aeons by an extremely patient extraterrestrial observer. Nothing, save a little hydrogen and helium, leaves the planet. And then, less than 20 years ago, the planet suddenly begins, like a dandelion gone to seed, to fire tiny capsules throughout the inner solar system. First they go into orbit around the earth. Six capsules set down on the moon and from each two small organisms emerge. Five little spacecraft enter the hellhole of Venus's atmosphere. More than a dozen are dispatched to Mars. Two spacecraft successfully traverse the asteroid belt, fly close to Jupiter and are ejected by its gravity into interstellar space.

We have entered, almost without noticing it, an age of exploration unparalleled since the Renaissance, when in just 30 years European people moved across the Western ocean to bring the entire globe within their ken. Our new ocean is the shallow disk of space occupied by the solar system. Centuries hence, our age may be remembered chiefly as the time when the inhabitants of the earth first made contact with the vast cosmos in which their small planet is embedded. —Carl Sagan' 1925 Television via Radio 'C. Francis Jenkins, radio photographic experimenter of Washington, D.C., has demonstrated apparatus by which moving objects, including a Dutch windmill and motion picture film, were sent by radio for five miles and reproduced on a miniature screen, 10 by eight inches. The transmitter was set up at station NOF, near Anacostia, D.C., and the receiver in Jenkins's laboratory. He predicts that the process will be perfected so that scenes at baseball games and prize fights can be broadcast over long distances.' Clearly Written Books 'Below are some of the recent books that can be recommended for clearness of treatment, obtainable from the Scientific American Book Department. Red-Lead and How to Use it in Paint, by Sabin White-Lead. Its Use in Paint, by Sabin The Science of Knitting, by Tompkins Carbureting and Combustion in Alcohol Engines, by Sorel, Woodward, Preston Evolution and Animal Intelligence, by Holmes I Believe in God and in Evolution, by Keen God or Gorilla, by McCann' 1875 Cincinnati is Center of U.S. 'The center of our population has traveled westward, keeping curiously near the 39th parallel of latitude, never getting more than 20 miles north or two miles south of it. In 80 years it has traveled only 400 miles, and it is now found nearly 50 miles eastward of Cincinnati, Ohio.' Spiritualist Rebuke 'Most of the organs of the spiritualists in this country are filled with insipid ghost matter, very tiresome and useless to all whose brains have not been softened by the spirit craze. The Spiritual Scientist, a weekly periodical, is an exception. Its editorial columns exhibit talent, while its conductors, with boldness, condemn as unworthy of true believers the printing of the unauthenticated trashy stuff delivered by common mediums. To its contemporary, the Banner of Light, it administers a severe rebuke for its agency in this matter, and alleges that for the past 10 or 12 years that journal has poured out a weekly stream of pretended spirit communications, of which not more than two in a hundred had contained anything beyond childish nonsense.' Huge Ganoids Ruled the Seas 'Professor J. S. Newberry gave descriptions of some newly discovered ancient fishes found in the rocks of Ohio. Among these was the entire bony structure of Dinichthys terrelli, the hugest of the old armor-plated ganoids. The dorsal shield weighed 30 pounds. Professor Newberry explained that the dipnoans of Africa and South America were descended from these ancient plated ganoids, and were the last remnants of a group of fishes which in the Devonian age not only ruled the seas, but were the most powerful and highly organized of living beings.'

Critics shouldn't block NASA's nuclear path to a moon base
Sean Duffy, NASA's interim administrator, proved that the U.S. is serious about establishing a lunar base when he announced the deployment of a 100-kilowatt nuclear reactor on the moon by 2030. The idea, although a sound one, is not without its critics. The announcement that the first element of a lunar base will be a nuclear reactor was logical. Nuclear power, unlike solar, is available 24/7 and thus does not require backup batteries during periods when the sun is not available. That the reactor is first means that every other element of the lunar base can be hooked up and powered up immediately. As NPR notes, a 100-kilowatt reactor on Earth would be able to power 70 to 80 private homes in the United States, so it could power a decent-sized lunar base. It would have to withstand the extremes of heat and cold on the moon, not to mention the possibility of moonquakes and meteor strikes. Instead of water to cool it, the reactor would simply radiate the heat it creates into space. The cost would be about $3 billion. Space lawyer Michelle Hanlon describes some of the legal aspects of placing a nuclear reactor on the moon, especially in context of the space race with China. While the Outer Space Treaty prohibits claims of national sovereignty on the moon, the establishment of a nuclear reactor, especially with a lunar base attached to it, grants the nation-state that does it some measure of control over the surrounding territory. Its Article IX requires that states act 'with due regard to the corresponding interests of all other States Parties to the Treaty.' The practical effect of the Article IX provision is that the first country to establish a lunar base on the moon's south pole would be able to claim control over some prime real estate, important where ice mining is likely to be an essential enterprise. Duffy is therefore correct that the U.S. and its allies should be first with a nuclear reactor and a lunar base before China can establish its own and thus exert control. The idea of a nuclear-powered lunar base is not without its critics. For example, a CBS News host opined that colonizing the moon was akin to the colonization of native peoples on Earth by European powers. Celebrity astrophysicist Neil deGrasse Tyson set him straight by pointing out that no native peoples exist on the moon or anywhere else in the solar system beyond Earth. The exchange elicited eyerolling on the Fox News show 'The Five.' But even there, some griping occurred. Dana Perino, who used to work for President George W. Bush, expressed considerable ennui about the whole concept of space travel. From the perspective of someone who has seen a space shuttle launch in person and watched men walk on the moon live on television, the attitude seems to be bizarre and dispiriting. Tyrus, the former wrestler turned social and political commentator, trotted out the 'let's solve problems on Earth before we go into space' trope that has been around since the beginning of the space age. The obvious answer has always been, 'Do both.' Ross Marchand, writing for Real Clear Science, noted the $37 trillion national debt and then claimed that building a lunar base would be just too expensive. He undermined his argument by comparing the 100-kilowatt lunar nuclear power plant to the 1-gigawatt reactors that exist on Earth and cost $10 billion to build (largely because of permitting and environmental regulation problems). Then he increased the estimated cost by a factor of 10 'or more.' Although NASA projects often do suffer cost overruns, $3 billion to $100 billion would be a little much, even for the space agency with its history of inefficiency. Marchand also trotted out the 'robots can explore space cheaper and better than humans' claim that was soundly debunked by the late, great lunar geologist Paul Spudis. In fact, returning to the moon and going on to Mars also polls well and has bipartisan political support, even it still has its critics. No great endeavor ever undertaken since the beginning of civilization has not had people saying it can't or shouldn't be done. The International Space Station, for example, drew fierce opposition and was almost cancelled more than once. The orbiting space laboratory is currently churning out a stream of scientific discoveries and technological innovations, confounding its early critics, who are long since forgotten. The lunar base and even Elon Musk's planned Mars colony will undergo a similar process. Future generations will find it difficult to imagine a universe where humans just occupied one world. Mark R. Whittington, who writes frequently about space policy, has published a political study of space exploration entitled ' Why is It So Hard to Go Back to the Moon? ' as well as ' The Moon, Mars and Beyond,' and, most recently,' Why is America Going Back to the Moon? ' He blogs at Curmudgeons Corner.
