Unprecedented Discovery of Ancient Landscape Beneath East Antarctic Ice Sheet Revealed by Scientists

By News Masher on October 24, 2023

Scientists have discovered a hidden landscape of hills and valleys beneath the East Antarctic Ice Sheet, estimated to be at least 14 million years old. The landscape was mapped using radar data from the European Space Agency's CryoSat-2 satellite, and the researchers warn that human-driven global warming could threaten to expose the ancient landscape. The findings were published in the journal Nature Communications and could help to better understand the history of the Antarctic ice sheet and how it has responded to climate change in the past.

Witness the Spectacular ‘Ring of Fire’ Solar Eclipse: Last Visible from American Skies Until 2039

By News Masher on October 14, 2023

On October 14th, 2023, the United States experienced a rare "ring of fire" annular solar eclipse, visible from Oregon to Texas. The moon passed between the Earth and the sun while at its farthest point, creating a crescent-shaped shadow and a "ring of fire" in the sky. Crowds gathered along the narrow path of the eclipse to cheer, and the eclipse coincided with an international balloon fiesta in Albuquerque. The next annular solar eclipse visible from American skies will be in June 21, 2039, passing only over Alaska.

NASA Unveils Historic Asteroid Sample Return Mission, Showcasing Most Samples Ever Returned to Earth

By News Masher on October 11, 2023

NASA has unveiled its first-ever asteroid sample return mission, with samples from the carbon-rich asteroid Bennu containing water molecules and clay minerals. Daniel Glavin, co-investigator for the mission, said the findings were far more than expected and the main sample chamber has yet to be opened. The mission marks a major milestone for NASA, with the findings to inform future asteroid exploration and research.

Ancient Human Footprints Found in White Sands National Park Confirm Earliest Evidence of Human Presence in the Americas

By News Masher on October 6, 2023

A new study published in the journal Science has confirmed that fossil human footprints discovered in White Sands National Park in New Mexico are likely the oldest direct evidence of human presence in the Americas, estimated to be between 21,000 and 23,000 years old. Researchers conducted tests to analyze the sediment layers in which the footprints were found, and their findings challenge the previous belief that humans arrived in the New World between 13,500 and 16,000 years ago. The findings of the study could have implications for the understanding of human migration patterns and the history of the Americas, and the researchers hope that their findings will encourage further research into the history of human presence in the Americas.

Three Scientists Awarded Nobel Prize in Physics for Exploring the World of Electrons Inside Atoms and Molecules

By News Masher on October 3, 2023

The 2020 Nobel Prize in Physics has been awarded to three scientists for their work in exploring the world of electrons inside atoms and molecules. Dr. Andrea Ghez and Dr. Reinhard Genzel were awarded for their work in discovering a supermassive compact object at the center of our galaxy, while Dr. Roger Penrose was awarded for his work in demonstrating a way to create extremely short pulses of light. Their work has enabled us to understand the behavior of electrons in atoms during the tiniest of split seconds, giving us a better understanding of the universe.

Nobel Prize in Medicine Awarded to Scientists for Groundbreaking Discoveries that Enabled Development of mRNA Vaccines Against COVID-19

By News Masher on October 2, 2023

Katalin Karikó and Drew Weissman have been awarded the 2023 Nobel Prize in Physiology or Medicine for their discoveries that enabled the development of mRNA vaccines against COVID-19. The Nobel Assembly praised the laureates for their work which has "fundamentally changed our understanding of how mRNA interacts with our immune system" and for contributing to the "unprecedented rate of vaccine development". This technology has been used to develop vaccines for a range of diseases, including COVID-19.

Remarkable Discovery of 6,200 Year Old Woven Grass Footwear in Southern Spain Uncovers New Insights into Our Ancestors

By News Masher on September 29, 2023

Archaeologists have made a remarkable discovery of the oldest woven grass footwear in Europe, estimated to be up to 6,200 years old, in a bat cave in southern Spain. Radiocarbon dating was used to date the objects, which include baskets, tools and sandals made from esparto grass. The discovery has forced researchers to rethink their assumptions about our human ancestors in the region, and the team is continuing to study the objects to learn more.
