Sawfish fossils suggest teeth likely evolved from body scales in ancient fish
Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating—an idea known as the "outside-in" hypothesis? Or did they evolve independent of s.....»»
NIST proposes barring some of the most nonsensical password rules
Proposed guidelines aim to inject badly needed common sense into password hygiene. Enlarge (credit: Getty Images) The National Institute of Standards and Technology (NIST), the federal body that sets technology standards.....»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Study shows that ancient reef-building stromatoporoids dodged extinction—at least temporarily
Will modern coral reefs go extinct? The answer is uncertain, but some of their ancient counterparts managed to dodge a bullet—for a while, at least......»»
ALICE probes the strong interaction three-body problem with new measurements of hadron–deuteron correlations
In an article recently published in Physical Review X, the ALICE collaboration presented its studies of correlations in the kaon–deuteron and proton–deuteron systems, opening the door to precise studies of the forces in three-body nuclear systems.....»»
Ingredients used in chewing gum help tilapia survive cold climates
Two common ingredients in ordinary chewing gum—Arabic gum and lecithin—have been found to help improve the overall health of tilapia, helping these fish survive better even in cold climates. This discovery paves the way for raising tilapia for fo.....»»

Medicinal tree successfully grown from 1,000-year-old seed found in cave
An international team of botanists, agriculturists and historians has successfully grown a mature tree from an ancient seed found in a cave in Israel. In their paper, published in the journal Communications Biology, the group describes where the seed.....»»
New evolutionary model revises the origins of biodiversity
An international team of scientists has made a discovery that could reshape our understanding of how global biodiversity evolved. By reconstructing the evolution of species over the past 45 million years, researchers found that the geographic origins.....»»
Afar mantle plume study offers new insight into deep Earth processes
Sophisticated analysis of tiny bubbles of ancient gas trapped in volcanic rocks, combined with new geophysical modeling, has cast new light on long-held assumptions about the deep Earth......»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
SSD vs. HDD: What’s the difference, and which drive type is best?
What's the difference between SSD vs. HDD? What kind of drive is right for you is going to depend on your situation, but we'd suggest you get at least one SSD......»»
Ancient DNA helps uncover the Iberian lynx"s potential secret weapon against extinction
Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a "genetic database" to fall back on to ad.....»»
Studying fossil extraction on Native lands and exploring the depths of untold histories
In 2019, historian Lukas Rieppel published a book about the history of dinosaur fossils and their excavation in the late 1800s to create museum displays......»»

Extreme polar light environment of the North and South Poles sustains biodiversity, researchers suggest
Researchers working in Finland propose that the unique light environment of the Earth's polar regions creates conditions that result in circumpolar hybrid zones around the North and the South Poles. These extreme conditions increase the synchrony of.....»»
A secret recipe for colorful and versatile animal crystals
What do fish, chameleons, crabs and Walter White, the chemistry teacher from "Breaking Bad," all have in common? The answer is that they all know how to make crystals. But, unlike the incorrigible White, who manufactured mind-altering methamphetamine.....»»
3D field-based tracking and field experiments of octopus and fish unlock the secrets of multispecies hunting
The diving gear is on, the cameras are ready—biologist Eduardo Sampaio and his colleagues are set to go. They dive in the Red Sea, scanning left and right underwater—and wonder: Where can an octopus hunting be found? Finally, they spot one. The t.....»»
