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.
NASA satellites revealed 14 active water areas beneath Antarctica; one lake drained 2 cubic km in 3 years
Scientists discovered active subglacial lakes beneath Antarctica's ice sheet. NASA satellite data revealed ice surface changes indicating water movement. These hidden lakes were found to fill and drain over short periods. This dynamic water system influences ice stream speeds and mass balance. The findings showed a hidden, active world beneath the frozen continent.
Nasa's 2028 Mars mission will send a nuclear spacecraft and three helicopters to explore Mars
NASA is planning an exhilarating mission for late 2028 that will test nuclear electric propulsion well beyond our planet. The SR-1 Freedom spacecraft will journey past Mars, releasing three helicopters similar to Ingenuity to explore the Martian landscape and locate potential subsurface ice reserves. The insights gained from this venture will not only refine our understanding of nuclear-powered spacecraft but also enhance future lunar energy systems and propulsion methods.
