Scientists Discover Brain Vascular Changes Associated with Alzheimer’s Disease

Credit: Freepik The blood-brain barrier (BBB)—a network of blood vessels and tissues that protects the brain from harmful substances in the blood—is disrupted in Alzheimer's disease. Researchers at the Mayo Clinic and collaborators have now identified unique molecular signatures of BBB dysfunction, potentially leading to new diagnostic and treatment methods. Discovery and Analysis of Molecular Signatures "These...

Something Strange is Occurring in Earth’s Inner Core

Scientists have proposed that Earth’s moon-sized inner core revolves independently of the mantle and crust, and that it is now backpedaling relative to those other layers.JOHAN63/ISTOCK/GETTY IMAGES PLUS A new study seems to support the contentious idea that the Earth's inner core's rotation has decelerated. Decades of earthquake data indicate that since around 2010, the...

The Bugatti Tourbillon Targets 1,800-Horsepower Perfection

The Bugatti TourbillonBugatti Two decades ago, the Veyron was introduced. Twelve years later, the Chiron arrived. Now, Bugatti's latest era begins with the Tourbillon—a luxury hybrid hypercar featuring a 277-mph (446 km/h), 1,800-hp naturally aspirated V16 engine with three electric motors. Priced at US$4 million, this timeless creation is crafted with meticulous precision akin to...

Breakthrough in Green Hydrogen Substitutes Water for Iridium

Credit: Depositphotos Hydrogen holds potential as a potent, eco-friendly fuel source, provided its production process is also environmentally sustainable. A recent report highlights the challenges in achieving genuinely green hydrogen, while a new study overcomes a hurdle in its production. According to a study released today in the journal Nature Energy, authored by Kiane de Kleijne...

Astronomers Witness the First Activation of a Supermassive Black Hole

A supermassive black hole in galaxy SDSS1335+0728 has lit up, possibly giving astronomers a look at how such beasts are awakened.M. KORNMESSER/ESO For the last four years, astronomers have observed the supermassive black hole at the center of SDSS1335+0728 undergo a transformation from a dim and inactive state to a bright and active one. This...

The Great Oxidation Event: A 200-Million-Year Pathway to Oxygenation

Studies of marine shales and isotopic data from the Great Oxidation Event period reveal dynamic oxygen fluctuations in Earth’s early atmosphere and oceans, highlighting the prolonged and complex nature of this critical evolutionary stage. Recent findings indicate that Earth's "Great Oxidation Event" unfolded over a span of 200 million years. Fresh research underscores the intricate nature...

The Solar System’s Largest Storm May Be Younger Than Previously Believed

Jupiter's Great Red Spot (GRS), a colossal anti-cyclonic storm larger than Earth, has intrigued astronomers since the 1600s. Its origins and lifespan are subjects of ongoing debate, raising questions about its continuity over centuries of observation. Initially noted in 1632, the GRS disappeared from astronomical records for 118 years until its rediscovery in the...

Online Support and Challenges in Deprescribing Antidepressants

Recent research indicates that individuals seeking to discontinue antidepressant medication are increasingly relying on online groups due to "insufficient support from medical professionals." This trend underscores a significant gap in care that needs urgent attention. Antidepressant use is rising globally, driven not by new prescriptions but by existing patients prolonging their medication intake. Guidelines from...

Electric Hypercar Breaks Rimac’s Record, Now Fastest EV

The production-intent Owl SP600 has smashed the Rimac Nevera's record to become the world's fastest electric hypercarAspark/MAT Japan's Aspark has declared its Owl SP600 electric hypercar the fastest in the world, surpassing the Rimac Nevera's impressive 2022 record by 26.7 km/h. "It has been about 10 years since we started working on the Owl hypercar," said...

Artificial Amber Preserves DNA for Long-Term Data Storage

DNA is a much denser data storage medium than anything humans can design, but it is fragile. Scientists have now mimicked nature by creating artificial amber to protect DNA for long-term data storage. A single gram of DNA can hold up to 215 petabytes (215 million GB) of data, making it possible to store the...
