"Pompeii of prehistoric plants" unlocks evolutionary secret: study
Spectacular fossil plants preserved within a volcanic ash fall in China have shed light on an evolutionary race 300 million years ago, which was eventually won by the seed-bearing plants that dominate so much of the Earth today......»»
Oceans were stressed preceding abrupt, prehistoric global warming
Microscopic fossilized shells are helping geologists reconstruct Earth's climate during the Paleocene-Eocene Thermal Maximum (PETM), a period of abrupt global warming and ocean acidification that occurred 56 million years ago. Clues from these ancien.....»»
Team of bioethicists and scientists suggests revisiting 14-day limit on human embryo
An international team of bioethicists and scientists contends it may be justified to go beyond the standing 14-day limit that restricts how long researchers can study human embryos in a dish. Going beyond this policy limit could lead to potential hea.....»»
WOX9: A jack of all trades
Researchers used CRISPR, a genome-editing tool, to figure out the hidden roles of a developmental gene called WOX9. It usually induces flower branching in tomatoes and influences embryo growth in a plant related to broccoli. By tweaking the DNA in th.....»»

Asteroid dust found in crater closes case of dinosaur extinction
Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.....»»
Using a multipronged approach to investigate the diet of ancient dogs
Coprolites, or fossilized feces, are often used to understand the dietary preferences of ancient civilizations. However, the samples are often contaminated, making the analysis difficult. A new study, published in Scientific Reports, uses different t.....»»
Large privately owned redwood forest is preserved in $24.7 million deal

Imaging the first moments of a body plan emerging in the embryo
Egg cells start out as round blobs. After fertilization, they begin transforming into people, dogs, fish, or other animals by orienting head to tail, back to belly, and left to right. Exactly what sets these body orientation directions has been guess.....»»
