Even if there"s life on TRAPPIST-1, we probably can"t detect it
If we ever find life on other worlds, it is unlikely to be a powerful message from space. It's certainly possible that an alien civilization specifically sends us a radio message like a scene out of Contact, but the more likely scenario is that we ob.....»»
Examining how stellar threats impact the habitable zone of exoplanets
When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have liquid surface water. It's a somewhat crude but helpful fir.....»»
Pathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a study led by Ingun Lund Witsø of the Norwegian University of Life Sciences, published November 6, 2024 in the open-access journal.....»»
New PFAS testing method could make water testing more affordable, portable and accessible
University of Massachusetts Amherst researchers have discovered a new way to detect per- and polyfluoroalkyl substances (PFAS) in water. This marks an important step forward in creating testing devices that are simpler, more cost-effective, faster an.....»»
The high cost of complexity: New study explores energy needs of multicellular life
Between 1.8 billion and 800 million years ago, earthly life was in the doldrums. During this period, called the "boring billion," the complexity of life remained minimal, dominated by single-celled organisms with only sporadic ventures into multicell.....»»
Gamma radiation converts methane into complex organic molecules and could explain the origin of life
Gamma radiation can convert methane into a wide variety of products at room temperature, including hydrocarbons, oxygen-containing molecules, and amino acids, according to a new article published in the journal Angewandte Chemie International Edition.....»»
Testing thousands of RNA enzymes helps find first "twister ribozyme" in mammals
The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA—a single-stranded molecule similar in many ways to DNA—like some modern viruses. This is because, like DNA, RNA can carry genetic information, but, lik.....»»

Deep sea rocks suggest oxygen can be made without photosynthesis, deepening the mystery of life
Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study demonstrates that oxygen may be produced without th.....»»
African Sahara "greening" can alter Northern Hemisphere climate, modeling study finds
Africa's Sahara Desert may be considered a vast expanse of barren sand with limited vegetation, an extreme environment for plants and animals to thrive, but life always finds a way. Indeed, vegetation growth in the desert has waxed and waned over mil.....»»
