In 1929, Benjamin and Estella Loomis gave Lassen Volcanic National Park 40 acres, a museum and a...
In 1914, homesteader Benjamin Loomis captured the dramatic eruptions of Lassen Peak through his photography. Along with his wife, Estella, he later established a museum and seismograph station on their land. This rich historical site was formally donated to the United States in 1929 and is now recognized as the Loomis Museum, serving to inform and engage visitors about the fascinating history of volcanic activity.
In 1867, New Zealand introduced brown trout for sport fishing; more than 60 million were released
In 1867, British settlers introduced brown trout to New Zealand, intending to enhance sport fishing. This decision led to the release of over sixty million trout, which had devastating effects on local fish populations, resulting in declines and even extinction of some native species. The presence of these invasive fish fundamentally changed stream ecosystems and insect behaviors, making their management a significant conservation challenge even today.
We are talking less to people than we used to; study finds drop in spoken words and social skills
From 2005 to 2019, the art of conversation has seen a notable decline, mainly due to the surge in digital interactions. This trend is particularly evident among younger generations who engage less in direct dialogue. While audio content offers entertainment, it lacks the personal touch of face-to-face communication. Rebuilding these small yet meaningful human connections is essential to enhancing our social bonds.
This coffee cup hid seeds in its paper; plant it after your last sip
In 2015, a groundbreaking proposal was unveiled for a coffee cup that can be planted. Made from recycled paper, this eco-friendly cup uniquely housed seeds intended for reforestation. Its innovative design protected the seeds from hot beverages while promoting biodegradation within 180 days. The Kickstarter campaign successfully attracted more than $21,000 from enthusiastic supporters, promoting a sustainable approach to disposable packaging by turning it into a planting resource.
Why everyone wants a rocket that comes back
China's LandSpace achieved a significant milestone by recovering its rocket's first stage after an orbital launch. This reusable rocket technology aims to drastically reduce spaceflight expenses and increase launch frequency. Several nations, including the US, Europe, Japan, and India, are actively pursuing similar advancements. India's approach involves a winged spaceplane-like vehicle designed for runway landings. This global competition is reshaping the future of space exploration and commercialization.
In 2014, scientists set off 23 blasts to uncover magma hidden beneath Mount St Helens
In a groundbreaking study, researchers utilized controlled explosions paired with seismic technology to investigate Mount St. Helens' subterranean magma systems. They discovered a magma-reservoir located between four to fifteen kilometers deep. This extensive analysis employed numerous instruments to track seismic waves within the volcano, yielding vital knowledge about magma movements. Such understanding is instrumental in forecasting volcanic activity and potential eruptions.
Scientists reidentify Ireland’s “Kerry Cow” bones as bear and wild boar, challenging farming theory
Ancient animal bones from Ferriters Cove are now identified as bear and wild boar. This reclassification challenges decades of evidence for early farming in Ireland. Previously thought to be cattle, these remains are now understood differently. Modern scientific techniques revealed the true identity of these ancient specimens. This discovery prompts a reconsideration of Ireland's prehistoric transition to agriculture.
Meet Jeremiah Bents, the Minnesota student who recreated Mars soil to test water cleanup
Jeremiah Bents, a Minnesota student, explored water filtration using Mars soil simulant. His project examined ammonia removal from contaminated water in a laboratory setting. This innovative work earned him the Earth Systems Science Award at a state science fair. He received guidance from university researchers and a NASA scientist. Bents' experiment demonstrated a practical application for future space missions.
Scientists turn plastic waste into protein cookies; food can tackle hunger and feed space crews
Researchers at Southern Illinois University Carbondale are developing protein-rich cookies made using plastic waste and agricultural waste. Called µBites, the cookies use PET plastic from bottles and discarded corn stalks and leaves. Programmed yeasts convert processed waste into proteins, fats, acids and flavouring molecules. The NASA-linked project is aimed at developing food for resource-limited environments, including future deep-space missions.
17-year-old Leon Wang finds 2 FDA-approved drugs that reduced Alzheimer’s-linked cell damage
A young student's research explored existing medicines for Alzheimer's disease protection. He identified two drugs, nintedanib and pirfenidone, showing protective effects in cell models. This drug repurposing approach offers a faster, less expensive research starting point. Wang's work highlights targeting APOE4 and brain blood vessel cell changes. His findings suggest further investigation into TGFβ pathway drugs is warranted.
