Geologists led by Dr Lydia Hallis from the University of Hawaii have examined a meteorite that formed on Mars more than 1 billion years ago to determine if conditions were ever right on the planet to sustain life. Miller Range 03346 nakhlite (NASA) The meteorite, called Miller Range 03346 nakhlite (MIL 03346), was recovered in 2003 in the Miller Range of Antarctica. About the size of a tennis ball...

A new study reported in the journal Nature Communications indicates that the Minoans, who 5,000 years ago established the first advanced Bronze Age civilization in present-day Crete, probably were descendents of the first Neolithic humans to reach the island around 7,000 BC and that they have the greatest genetic similarity with modern European populations. The study highlights the high affinity...

Paleontologists from the United States and Canada have described a new species of dinosaur named Albertadromeus syntarsus, the smallest herbivorous dinosaur known from Canada. Life reconstruction of Albertadromeus syntarsus (Julius T. Csotonyi) Albertadromeus syntarsus lived in what is now southern Alberta in the Late Cretaceous about 77 million years ago. It was identified from a partial hind leg,...

Physicists Measure Ionization Potential of Astatine, Rarest Naturally Occurring Element on Earth

Resonance ionization laser ion source of ISOLDE (CERN)

In ground-breaking experiments conducted at the radioactive isotope facility ISOLDE at CERN, a multinational research team has investigated the atomic structure of astatine (At), the rarest atom on our planet. Resonance ionization laser ion source of ISOLDE (CERN) Astatine was discovered by D. Corson and co-workers in 1940 by bombarding a bismuth target with alpha particles. The most stable isotope...

Researchers Determine Age of Weaning in Neanderthals

Neanderthal family (Field Museum)

Scientists led by Dr Manish Arora from the Icahn School of Medicine at Mount Sinai have reported that they can now use fossil teeth to calculate when a Neanderthal baby was weaned. Neanderthal family (Field Museum) Their new technique is based in part on knowledge gained from studies of teeth from human infants and from macaques at the California National Primate Research Center. Prof Katie Hinde...
