Study of nearly 6,000 children shows Ritalin and Adderall activate the brain’s reward centers rather than attention networks, challenging long-held beliefs.For decades, doctors believed attention-deficit/hyperactivity disorder (ADHD) medications like Ritalin and Adderall worked by sharpening a person’s focus. They may have been wrong. A study suggests these drugs actually work by making tasks feel more rewarding—basically tricking the brain into caring about homework, chores, and other mundane activities. “Essentially, we found that stimulants pre-reward our brains and allow us to keep working at things that wouldn’t normally hold our interest—like our least favorite class in school,” Dr. Nico Dosenbach, senior...

The earthquake in Shaanxi China on January 23, 1556 was not, by any means, the most powerful earthquake experienced in human history. Still, an inscription from the time ends, simply, "Since the beginning of time, there has been no earthquake comparable to this one." Note: Just because you can think up a reason to criticize doesn't mean that you are obligated to do so. Pedantic is not a compliment folks.

Explanation: Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light...

Eight emperors are shown on the coins. However, three of the coins featured an unexpected ruler -- Eugenius, who only ruled the Western Roman Empire from 392 to 394 CE. Eugenius came to power partially due to the support of a powerful general Arbogast. Arbogast was a Frank -- the Germanic-speaking peoples who invaded the Western Roman Empire during the Fifth Century.When Christianity was becoming increasingly dominant in the Roman Empire, Eugenius attempted to restore pagan practices and traditions. His brief reign was marked by conflict and political instability. Eugenius primary opponent -- Eastern Roman Emperor Theodosius I -- eventually...

My last two posts have been about the new Federal Reference Manual on Scientific Evidence, just out (December 31) from the Federal Justice Center. The Chair of that Center is U.S. Chief Justice John Roberts. The latest version of the Manual is the Fourth Edition. The prior version in 2011 was the Third Edition; and there were also two prior Editions from 2000 and 1994. In those previous two posts, I principally criticized a newly-added chapter in the Fourth Edition titled “Reference Guide on Climate Science.” Today, I want to take a look at another chapter titled “How Science Works.”...

In 2003, metal detectorist Brian Malin found the Chalgrove Hoard near Chalgrove, around 10 miles from Oxford. Inside a huge jar were nearly 5,000 late Roman coins, mostly copper-alloy radiates with that familiar "silvered" look that is really just debased coinage from the Crisis of the Third Century. After numismatists worked through the hoard coin by coin, one piece stood out. It looks ordinary, but the legend names an emperor who should not exist: Domitianus.The new Roman emperor discovered from a coin - Domitianus | 16:19TopRomanFacts | 37.2K subscribers | 25,111 views | January 9, 2026YouTube transcript reformatted at textformatter.ai...

Hosting the Winter Olympics will be more challenging in the future as global warming impacts host cities traditionally known for climates suitable for competitions such as skiing and snowboarding, according to climate scientists. The 2026 Winter Olympics are about to kick off, but the Milano Cortina Games will take place in a much warmer world than in years past. Average temperatures in Cortina, Italy, have risen by 6.4 degrees Fahrenheit since the region first hosted the Winter Olympics in 1956, according to a recent analysis by Climate Central. The warming trends have led to fewer freezing days and a shortage...

The familiar medieval Arthurian myths of a noble King ruling over his kingdom from Camelot, supported by his Round Table of loyal and brave knights who seek for the Holy Grail and slay dragons, is a legend that has been engaged with by English kings ever since the 13th Century. By the 14th Century, these tales provided a model for their kingship. What you may not know about, is the clash of cultures that occurred in the 12th Century, that led to the making, breaking and redefining of Arthur's story. Join author and medieval historian Matt Lewis as he delves...

A sweeping new report from the World Health Organization found that up to four in 10 cancer cases around the globe could be prevented with lifestyle changes. In the large international study, researchers identified 30 modifiable risk factors that fuel the disease — including, for the first time, nine cancer-causing infections. “This is the first global analysis to show how much cancer risk comes from causes we can prevent,” Dr. André Ilbawi, the WHO’s team lead for cancer control and the study’s author, said in a press release. “By examining patterns across countries and population groups, we can provide governments...

Explanation: Active galaxy NGC 1275 is the central, dominant member of the large and relatively nearby Perseus Cluster of Galaxies. Wild-looking at visible wavelengths, the active galaxy is also a prodigious source of x-rays and radio emission. NGC 1275 accretes matter as entire galaxies fall into it, ultimately feeding a supermassive black hole at the galaxy's core. Narrowband image data used in this sharp telescopic image highlights the resulting galactic debris and filaments of glowing gas, some up to 20,000 light-years long. The filaments persist in NGC 1275, even though the turmoil of galactic collisions should destroy them. What keeps...

Of the more than 4,500 stars known to have planets, one puzzling statistic stands out. Even though nearly all stars are expected to have planets and most stars form in pairs, planets that orbit both stars in a pair are rare. Of the more than 6,000 extrasolar planets, or exoplanets, confirmed to date - most of them found by NASA's Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS) - only 14 are observed to orbit binary stars. There should be hundreds. Where are all the planets with two suns, like Tatooine in Star Wars? ... ... Over time,...

SANTA FE — The highest-profile climate change bill under consideration during this year’s 30-day legislative session passed its first Senate committee hearing Tuesday, but only after weathering a broad blast of opposition from business and industry groups. After five hours of public testimony and debate, the Senate Conservation Committee voted 5-4 to advance the Clear Horizons Act to its next assigned committee. The vote on the legislation, Senate Bill 18, broke down largely along party lines, with Sen. Joseph Cervantes, D-Las Cruces, joining the committee's three Republican members in casting "no" votes. He voiced concern the legislation could lead to...

Explanation: Most galaxies don't have any rings -- why does this galaxy have three? To begin, a ring that's near NGC 1512's center -- and so hard to see here -- is the nuclear ring which glows brightly with recently formed stars. Next out is a ring of stars and dust appearing both red and blue, called, counter-intuitively, the inner ring. This inner ring connects ends of a diffuse central bar of stars that runs horizontally across the galaxy. Farthest out in this wide field image is a ragged structure that might be considered an outer ring. This outer ring...

Scientists watching the nearby Fomalhaut star system have directly seen two protoplanets smash together for the first time. Then, they saw it happen again...The Fomalhaut system is no stranger to such crashes. It's famously known as the "Eye of Sauron" due to its resemblance to the fiery, all-seeing eye from J.R.R. Tolkien's Lord of The Rings franchise. The likeness comes from the spectacular dust belt that surrounds Fomalhaut at a distance of 133 astronomical units (AU), with one AU being equal to 93 million miles (150 million km) — the average distance between the sun and Earth.

Jupiter is slightly smaller and flatter than scientists thought for decades, a new study finds. Researchers used radio data from the Juno spacecraft to refine measurements of the solar system's largest planet. Although the differences between the current and previous measurements are small, they are improving models of Jupiter's interior and of other gas giants like it outside the solar system, the team reported Feb. 2 in the journal Nature Astronomy. "Textbooks will need to be updated," study co-author Yohai Kaspi, a planetary scientist at the Weizmann Institute of Science in Israel, said in a statement. "The size of Jupiter...

A new study published today (February 2) in Nature Geoscience finds that shifts in the West Antarctic Ice Sheet (WAIS) closely followed changes in marine algae growth in the Southern Ocean during past ice ages. However, the relationship did not work in the way scientists long assumed. The link centers on iron-rich sediment carried into the ocean by icebergs breaking away from West Antarctica. Iron typically acts as a nutrient that supports algae growth. But when researchers examined a sediment core collected in 2001 from the Pacific sector of the Southern Ocean, taken from more than three miles below the...

According to a statement released by the University of Vienna, an international team of researchers has identified a rare genetic condition in the remains of a mother and daughter who were buried in an embrace in the same grave more than 12,000 years ago. The burial was discovered in 1963 at Grotta del Romito in southern Italy. Romito 1, the remains of a woman who stood under five feet tall, held the remains of Romito 2, an adolescent girl with pronounced limb shortening, and an estimated height of about 3.5 feet. DNA analysis also showed that the daughter carried two...

BASF plant in Ludwigshafen, 1881.In its ‘Climate & Energy’ newsletter on Thursday, the Wall Street Journal’s report on Germany’s chemicals industry headlined ‘The Agonising Decline of One of Europe’s Core Industries’ reads less like an industry report than a forensic examination of an industrial autopsy. Once Europe’s formidable manufacturing powerhouse, Germany is now presiding over the steady dismantling of one of its most foundational industries – chemicals – under the combined weight of self-inflicted energy scarcity, climate moralism and geopolitical miscalculation. In Politico’s view, the auto sector has already assumed the role of Exhibit A in Germany’s economic self-harm. But...

As discussed in the previous post, the Federal Judicial Center’s recently-updated Reference Manual on Scientific Evidence contains a new chapter on Climate Science. That chapter focuses on the promoting the hocus pocus of “attribution” studies that seek to blame every latest hurricane or flood or drought on human emissions of CO2, and thus on fossil fuel producers in particular. In my post, I characterized the authors’ write-up of the methodology of these attribution studies as relying on “logical fallacy,” and as “double-talk and bafflegab.” But I think that I inadequately articulated the nature of the fallacy. So I will try...
