Exotic Indium Nuclei

The isotope tin-100 is of interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers. In new research, physicists from the ISOLTRAP experiment at CERN’s Isotope mass Separator On-Line (ISOLDE) facility performed direct mass measurements …

Prehistoric New Guineans

As early as 18,000 years ago, early foragers in the montane rainforests of New Guinea preferentially collected eggs of cassowaries (Casuarius sp.) in late stages of embryonic growth and may have hatched them to rear chicks, according to an analysis of ancient eggshells from two Late Pleistocene/Early Holocene rock shelter …

Superionic Water’s

Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase of water where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lattice — with unprecedented resolution. Hydrogen atoms diffuse easily between the superionic …

Ankylosaur Unearthed

The newly-discovered dinosaur species, Spicomellus afer, is the earliest-known ankylosaur and the first ankylosaur to be named from Africa. Life reconstruction of the armored dinosaur Borealopelta markmitchelli, which lived in what is now Alberta, Canada, some 110 million years ago, eating ferns.

Layers of Graphene

To truly understand the essence of something, pelt it with projectiles. That has long been the preferred approach of some physicists, anyway. These scientists routinely study the subtle properties of solids by bombarding them with charged particles and watching for those that bounce off, get stuck or pass through to …

Water Splitting Electrocatalyst

Researchers in Japan have synthesised nanoporous ultra-high-entropy alloys that contain 14 elements. Tests showed the alloys were capable of splitting water and performed better than commercial platinum-based hydrogen evolution reaction catalysts and iridium-based oxygen evolution reaction catalysts. ‘Most conventional alloy catalysts contain a primary metal constituent with high atomic percentage, …

Vampire Bats

During nightly foraging trips, closely bonded females of common vampire bats (Desmodus rotundus) depart their roost separately, but often reunite far outside the roost to hunt together, says a new paper published today in the journal PLoS Biology. The common vampire bats (Desmodus rotundus). Image credit: Uwe Schmidt. Vampire bats …

Bipedal Dinosaurs

The tail of bipedal non-avian dinosaurs played a role analogous to the swinging arms of humans during walking and running, according to new research led by Harvard University’s Dr. Peter Bishop. Computer simulations of running locomotion in a modern tinamou bird (brown) and the extinct theropod dinosaur Coelophysis (green). Gray …

Biofluorescence

An international team of researchers led by the University of Georgia has documented ultraviolet biofluorescence in live southeastern pocket gophers (Geomys pinetis) and in museum specimens of four additional gopher species. Southeastern pocket gophers (Geomys pinetis) are biofluorescent, giving off a colored glow when illuminated with UV light. Image credit: …
