A 4.45 billion-year-old crystal from Mars reveals the planet had water from the beginning
Water is ubiquitous on Earth—about 70% of Earth's surface is covered by the stuff. Water is in the air, on the surface and inside rocks. Geologic evidence suggests water has been stable on Earth since about 4.3 billion years ago......»»
Unusual supernova observations grant astronomers a peek into the cosmic past
An international team of researchers has made new observations of an unusual supernova, finding the most metal-poor stellar explosion ever observed......»»
UK water companies now have to release live sewage spill data—why more transparency is key to cleaner rivers
For the first time, anyone in England can now access real-time information of where combined sewer overflows (CSOs) are discharging untreated wastewater into our waterways. This week, all water companies published details of how anyone can access the.....»»
Milestone legal case from 35 years ago holds important lessons for how courts deal with scientific evidence today
This month marks 35 years of DNA evidence being used in Australian legal cases. But unlike DNA firsts in other countries, Australia's is perhaps the most significant legal milestone that is practically unheard of......»»
Astronomers discover a rare group of dwarf galaxies
Astronomers from the Yonsei University in Seoul, South Korea and elsewhere have discovered a rare isolated group of five star-forming dwarf galaxies in the local universe. The finding was reported in a research paper published November 19 in The Astr.....»»
Molecular morphers: DNA-powered gels shape-shift on command
Johns Hopkins engineers have developed gel strips that change shape when given chemical instructions written in DNA code. These "gel automata," measuring just centimeters, can grow or shrink, transforming from one letter or number to another when tri.....»»
New maps show high-risk zones for whale-ship collisions—vessel speed limits and rerouting can reduce the toll
Imagine you are a blue whale swimming up the California coast, as you do every spring. You are searching for krill in the Santa Barbara Channel, a zone that teems with fish, kelp forests, seagrass beds and other undersea life, but also vibrates with.....»»

Gene regulation study reports surprising results: Extensive regions of DNA belong to multiple gene switches
Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they.....»»
Oldest direct evidence of hot water activity on Mars found
New Curtin University-led research has uncovered what may be the oldest direct evidence of ancient hot water activity on Mars, revealing the planet may have been habitable at some point in its past......»»
Earliest fish-trapping facility in Central America discovered in Maya lowlands
An archaeologist from the University of New Hampshire and her team have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland we.....»»
Ancient fish-trapping network supported the rise of Maya civilization
The Maya were landscape engineers on a grand scale, even when it came to fishing. On the eve of the rise of the Maya civilization, people living in what’s now Belize turned a wh.....»»
Nano-patterned copper oxide sensor provides rapid ultra-low hydrogen detection
Hydrogen is becoming an increasingly popular choice as we shift towards cleaner energy. It can be burned like traditional fuels, producing only water as a byproduct, and can generate electricity when used in fuel cells. However, as hydrogen productio.....»»
Scientists develop method "tetraplex digital PCR assay" for detecting DNA of invasive snakes in Florida
Scientists at the University of Florida have developed a pioneering tool to bolster Florida's defenses against invasive species: a DNA-based environmental monitoring test that can pinpoint where they've been, aiding eradication efforts......»»
New technique points to unexpected uses for snoRNA across many cell types
Dynamic, reversible modifications of DNA and RNA regulate how genes are expressed and transcribed, which can influence cellular processes, disease development, and overall organismal health. Small nucleolar RNAs (snoRNAs) are a common but overlooked.....»»
"Doomsday fish" washed ashore in California, but what does that mean?
If one oarfish landing on a beach is a sign of a disaster to come, how bad will it be if three wash up in quick succession?.....»»
Study reveals RNA"s unknown role in DNA damage repair
A multi-institutional team of researchers, led by Georgia Tech's Francesca Storici, has discovered a previously unknown role for RNA. Their insights could lead to improved treatments for diseases like cancer and neurodegenerative disorders while chan.....»»

Researchers investigate health risks of potentially toxic elements in surface water in Tarim River Basin, China
Potentially toxic elements (PTEs) in surface water in arid areas can pose a serious threat to natural environment and human health......»»
Origin of life research finds RNA can favor both left- and right-handed proteins
The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA emerged—can favor making the building blocks of proteins.....»»
