Needle-free ultrasound vaccine deliveryResearchers are investigating the potential of a painless, needle-free vaccine delivery by ultrasound. The method uses cavitation, which is the formation and popping of bubbles in response to a sound wave. Though initial in vivo tests reported 700 times fewer vaccine molecules were delivered by the cavitation approach compared to conventional injection, the cavitation approach produced a higher immune response. The researchers theorize this could be due to the immune-rich skin the ultrasonic delivery targets. The result is a more efficient vaccine that could help reduce costs and increase efficacy.

Exposure to chemicals found in many household products can lower odds of getting pregnantExposure to phthalates, a group of plasticizing and solvent chemicals found in many household products, was linked to a lower probability of getting pregnant, but not to pregnancy loss, according to research by a University of Massachusetts Amherst environmental and reproductive epidemiologist.

Doctor Who festive specials linked to lower death ratesA new "Doctor Who" episode shown during the festive period, especially on Christmas Day, is associated with lower death rates in the subsequent year across the UK, finds a study published in the Christmas issue of The BMJ.

3,000-year-old Ancient Puebloan calendar found on Colorado borderPolish archaeologists have discovered ancient Native American 3,000-year-old artworks carved into rock at a site on the Colorado-Utah border.

Resonant Stratification In Titan's Global Ocean - AstrobiologyTitan's ice shell floats on top of a global ocean revealed by the large tidal Love number k2=0.616±0.067 registered by Cassini.

Titan Awaits: NASA’s Dragonfly Gears Up for Groundbreaking Exploration of Saturn’s MoonNASA's Dragonfly mission to Titan advances to final design phase in 2024, with a re-planned launch date in 2028. The mission aims to explore Titan using a rotorcraft-lander and involves collaborations with multiple agencies. NASA’s Dragonfly mission has been authorized to proceed with work on fin

Astronomers detect almost 100 new extremely metal-poor galaxiesBy analyzing the early data from the Dark Energy Spectroscopic Instrument (DESI), an international team of astronomers has identified 95 new extremely metal-poor galaxies at a low redshift. The finding is detailed in a paper published December 1 on the pre-print server arXiv.

Landmark Melanoma Vaccine Could Be Available in Just 2 YearsModerna CEO Stephane Bancel told AFP his company's experimental vaccine against melanoma could be available in as little as two years, in what would amount to a landmark step against the most serious form of skin cancer.

A Trip to RememberThe link between dementia and neuroplasticity inspires researchers to test psychedelics as a potential treatment for cognitive impairment.

A substantial number of Parkinson's disease cases can be attributed to preventable risk factors, researcher saysNew research published by neurology researchers from the University of Alabama at Birmingham in npj Parkinson's Disease found that preventable risk factors play a significant role in a person's potential of developing Parkinson's disease.

Study shows how Rembrandt broke new ground with lead-based impregnation of canvas for The Night WatchNew research has revealed that Rembrandt impregnated the canvas for his famous 1642 militia painting "The Night Watch" with a lead-containing substance even before applying the first ground layer. Such lead-based impregnation has never before been observed with Rembrandt or his contemporaries. The discovery, published today in Science Advances, underlines Rembrandt's inventive way of working, in which he did not shy away from using new techniques.

The World's Oldest Settlements Were Built by a Culture Nobody ExpectedThousands of years before ancient people in Central Eurasia learned to farm, hunter-gatherer groups in the subarctic were building some of the first permanent, fortified settlements, challenging the notion that agriculture was a prerequisite for societies...

Ancient Stars Could Make Elements With More Than 260 ProtonsElements heavier than iron, like gold or platinum, were created when massive stars died or through colliding neutron stars. Some of our heavy elements on Earth resulted from an even heavier element decaying through fission. Astronomers studied several stars and found elements that must have been formed through the death of previous generations of stars and the fission of their matter. Some of these elements would have been more than an atomic mass of 260.

Sun Unleashes Mighty X2.8 Fury: NASA Captures Stellar SpectacleNASA observed a significant X2.8 solar flare on December 14, 2023, with potential impacts on Earth's technological systems, monitored by NOAA's Space Weather Prediction Center.
