Why can't robots outrun animals?      (via sciencedaily.com)     Original source 

Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.

A university lecture, with a dash of jumping jacks      (via sciencedaily.com)     Original source 

A university professor has found a way to help students -- and himself -- power through long lecture classes: exercise breaks. A new study showed that five-minute exercise sessions during lectures were feasible and that students reported positive impacts on their attention and motivation, engagement with their peers and course enjoyment.

Researchers show it's possible to teach old magnetic cilia new tricks      (via sciencedaily.com)     Original source 

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed.

Eruption of mega-magnetic star lights up nearby galaxy      (via sciencedaily.com)     Original source 

While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.

A novel universal light-based technique to control valley polarization in bulk materials      (via sciencedaily.com)     Original source 

Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major applications linked to the control and analysis of different properties for 2D and 3D materials, which can in turn enable the advancement of cutting-edge fields such us information processing and quantum computing.

Lead-vacancy centers in diamond as building blocks for large-scale quantum networks      (via sciencedaily.com)     Original source 

A lead-vacancy (PbV) center in diamond has been developed as a quantum emitter for large-scale quantum networks by researchers. This innovative color center exhibits a sharp zero-phonon-line and emits photons with specific frequencies. The PbV color center stands out among other diamond color centers due to its ability to maintain optical properties at relatively high temperatures of 16 K. This makes it well-suited for transferring quantum information in large-scale quantum networks.

Bioluminescence first evolved in animals at least 540 million years ago      (via sciencedaily.com)     Original source 

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.

Squids' birthday influences mating      (via sciencedaily.com)     Original source 

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 tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.

Frog species evolved rapidly in response to road salts      (via sciencedaily.com)     Original source 

When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.

Wake up and die: Human brain neurons re-entering the cell cycle age quickly shift to senescence      (via sciencedaily.com)     Original source 

Post-mitotic neurons in the brain that re-enter the cell cycle quickly succumb to senescence, and this re-entry is more common in Alzheimer's disease, according to a new study. The phenomenon may provide an opportunity to learn more about the neurodegeneration process, and the technique used to make this discovery is readily applicable to other inquiries about unique populations of cells in the brain.

Perfecting the view on a crystal's imperfection      (via sciencedaily.com)     Original source 

Hexagonal boron nitride (hBN) has gained widespread attention and application across various quantum fields and technologies because it contains single-photon emmiters (SPEs), along with a layered structure that is easy to manipulation. The precise mechanisms governing the development and function of SPEs within hBN have remained elusive. Now, a new study reveals significant insights into the properties of hBN, offering a solution to discrepancies in previous research on the proposed origins of SPEs within the material.

Fossil frogs share their skincare secrets      (via sciencedaily.com)     Original source 

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 frogs is due to preservation of ancient skin remnants.
