The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become ‘consorts’ which fight for mating opportunities. Those which hatch later become ‘sneakers,’ which use more clandestine mating tactics. Researchers found that the mating …
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years. …

In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics. In a significant development in the field of …

The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife …

A genetic propensity to higher circulating levels of lipids containing arachidonic acid, an omega-6 polyunsaturated fatty acid found in eggs, poultry, and seafood, has been found to be linked with a lower risk for bipolar disorder. This new evidence paves the way for potential lifestyle or dietary interventions. A genetic propensity to higher circulating levels …

Researchers have uncovered a remarkable metal alloy that won t crack at extreme temperatures due to kinking, or bending, of crystals in the alloy at the atomic level. Unlike most materials, the new alloy keeps its shape and resists cracking at both high and low temperature extremes, making it potentially suitable for demanding applications like …
Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts — it’s all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil …
Researchers describe the steps they took to manipulate DNA and proteins — essential building blocks of life — to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems and diagnostic tools. Researchers describe the steps they …

Researchers have developed a compact and lightweight single-photon airborne lidar system that can acquire high-resolution 3D images with a low-power laser. This advance could make single-photon lidar practical for air and space applications such as environmental monitoring, 3D terrain mapping and object identification. Researchers have developed a compact and lightweight single-photon airborne lidar system that …
