Presentation:
Join Jessica Vineyard, aka Ms. Galaxy, as she takes you on a journey into the farthest reaches of the cosmos. Ms. Galaxy's mission is to make astronomy fun, entertaining, and accessible to everyone. This is a don’t-miss opportunity!
The Hubble Space Telescope, launched in 1990, and the James Webb Telescope, launched in 2021, have expanded our view of the universe beyond all expectations. Utilizing some of the phenomenal images that these space telescopes have sent back to our home planet, Ms Galaxy will share her extensive knowledge of the stars and deep sky objects, including globular clusters, galaxies, supernovas, and more. Jessica founded the Southern Oregon Skywatchers Astronomy Club in 1993 and was president for five years. She co-hosted The Milky Way Starlight Theater on Jefferson Public Radio and has taught astronomy to the public for over thirty years.

Forget LASIK: Safer, cheaper vision correction could be coming soonScientists are developing a surgery-free alternative to LASIK that reshapes the cornea using electricity instead of lasers. In rabbit tests, the method corrected vision in minutes without incisions.

Ex-Google exec says degrees in law and medicine are a waste of time because they take so long to complete that AI will catch up by graduation“Higher education as we know it is on the verge of becoming obsolete,” the former Google AI leader told Fortune.

Study shows sound can make beer brew fasterŌtākou Whakaihu Waka researchers have hit the right note to cut down the time it takes to brew beer without altering its flavor. They have found playing audible sound (white noise) while making beer can reduce the fermentation process by 21–31 hours without significantly affecting the flavor.

Unitree Just Launched Its Most Affordable Humanoid Robot YetIn a market where humanoid robots often come with staggering price tags, Unitree has made waves with the launch of its R1 humanoid robot, starting at

Perplexity Just Offered To Buy Chrome For $34.5 BillionArtificial intelligence start-up Perplexity has made an unexpected $34.5 billion (£25.6bn) takeover bid for Google’s Chrome browser, claiming the d

Only the humpback whale is capable of bubble-net feeding, study findsIn a surprising discovery, a new study reveals that among seven species of baleen whales, only the humpback is capable of the high-performance turns required for its signature bubble-net feeding strategy. The research, led by recent University of Hawaiʻi at Mānoa graduate Cameron Nemeth, shows humpbacks use their unique pectoral flippers to achieve this maneuver, shedding new light on the biomechanics of this iconic feeding strategy.

Before Whales Took to the Sea, These Ten Species Walked on LandThe creatures, which ranged in size from that of a fox to more than 50 feet long, divided their time between the coast and the water

North Pacific waters are acidifying more rapidly below the surface, research revealsCarbon dioxide in the atmosphere enters the ocean at the surface and has been increasing the acidity of Pacific waters since the beginning of the industrial revolution over 200 years ago. A new study, led by University of Hawai'i at Mānoa oceanographers, revealed that the ocean is acidifying even more rapidly below the surface in the open waters of the North Pacific near Hawai'i.

3 experts reveal how psychedelics can expand the walls of perceptionWhat happens when the boundaries of “you” disappear? James Fadiman, PhD, Jamie Wheal, and Matthew Johnson, PhD, explore how supported experiences with psychoactive drugs can dissolve identity and reveal a deeper reality.

Solar-powered photoelectrochemical system converts nitrate in wastewater into high-value ammoniaA research team affiliated with UNIST has unveiled a technology that transforms nitrates found in wastewater into ammonia, a vital chemical and promising energy carrier, without carbon emissions. This advancement not only offers a sustainable method for ammonia production but also contributes to wastewater purification efforts.

Gold refuses to melt at temperatures hotter than the Sun’s surfaceFor the first time, researchers have measured atomic temperatures in extreme matter and found gold surviving at 19,000 kelvins, more than 14 times its melting point. The result dismantles a 40-year-old theory of heat limits.

A ‘Fully Wireless Society’ Could Be Made Possible With Japanese Scientists’ BreakthroughWireless charging may soon become even more efficient and reliable, thanks to a pioneering machine learning approach developed by researchers at Chiba

Ancient hominids made long road trips to collect stone for toolsA Kenyan site shows early hominids transported stone 13 kilometers for toolmaking as early as 2.6 million years ago.

The "Big Bang Galaxy" --Brightest in the Early Universe at 13 Billion Years Old Discovered to Harbor Carbon | The Daily GalaxyUntil summer of 2018, the earliest stars in the universe were thought to lack elements heavier than helium, such as carbon, the building block for life on

In Africa, heat waves are hotter and longer than 40 years ago, researchers sayHeat waves—prolonged periods of abnormally hot weather—influence egg prices, energy bills and even public transit. And they're becoming more common as temperatures increase.

More drought brings earlier autumn leaf fall, Northern Hemisphere study findsThe progression of leaf coloring from green to the reds, oranges, and yellows of the fall season can be a spectacular sight to behold, but this process is also an important part of a plant's developmental cycle.

Human influence reduces natural land carbon stocks by 24%, study findsHuman activities, such as deforestation and the expansion of agricultural areas, have a massive impact on the natural state of ecosystems. As a result, large amounts of carbon are released into the atmosphere, contributing substantially to anthropogenic climate change.
