Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present。 Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives。 The researchers say future missions should focus not only on finding life, but als
A new study suggests Earth may have been sending tiny hitchhikers to Venus for billions of years。 Researchers found that asteroid impacts could launch microbes into space, where some might survive the journey and end up suspended in Venus' clouds。 If future missions detect life there, there's a surprising chance it didn't originate on Venus at all—
Scientists exploring ancient seafloor rocks in Morocco discovered mysterious wrinkle patterns where they were never expected to occur。 These structures are normally linked to microbial mats in shallow, sunlit waters, yet the rocks formed hundreds of feet below the surface in darkness。 Evidence indicates that chemosynthetic microbes created the wrin
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species。 Even more surprising, some show little sign of physical decline as they age。 Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helpin
A cave in New Zealand has yielded fossils from a lost ecosystem that existed about 1 million years ago, including a possible flying ancestor of the kākāpō。 The discovery reveals that volcanoes and climate upheaval were reshaping the country’s wildlife and driving extinctions long before humans arrived
Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer’s-related brain changes。 The results challenge the idea that fish oil pills can help prevent Alzheimer’s and shift attention toward overall diet and lifestyle instead
Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy。 The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago。 Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly
Astronomers studying the rare supernova SN 2021yfj discovered material from one of the deepest layers of a dying star, providing a rare look at its hidden interior。 The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life
Hawaii researchers are giving old fishing nets and recycled plastic a second life by mixing them into asphalt roads。 Early tests found these roads didn't release more plastic particles than standard pavement, with tire wear overwhelming any plastic signal from the recycled material。 If future studies confirm the roads are durable, the technology co
What if consciousness isn’t limited to brains like ours。 Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth。 Drawing on the vastness of the universe and the likely existence of countless alien civiliza
SETI scientists searched the interstellar object 3I/ATLAS for radio signals that could indicate extraterrestrial technology but found nothing beyond human-made interference。 Even so, the rapid-response observations helped confirm the object's natural origin and showcased how future interstellar visitors can be investigated for signs of intelligent
