Dutch researchers are seeking to add a new, largely untapped renewable energy source to the world's energy mix with the opening of a "Blue Energy" test facility on Wednesday.
Graphene, impermeable to all gases and liquids, can easily allow protons to pass through it, University of Manchester researchers have found.
Warfare not only hastened human technological progress and vast social and political changes, but may have greatly contributed to the evolutionary emergence of humans' high intelligence and ability to work together toward common goals, according to a new study from the National Institute for Mathematical and Biological Synthesis (NIMBioS).
(Phys.org) —A team of researchers working at the University of Oxford has found that quantum bits (qubits) based on trapped calcium ions can be both manipulated and fashioned to store qubits with higher fidelity than any other method seen thus far. In their paper published in Physical Review Letters, the team describes how they built a means for testing the feasibility of using Ca+ ions as the basis for quantum computing and what they found in doing so.
'Tis the season for airplane travel. We may be looking forward to getting where we're going, but most aspects of the travel itself are merely endured. There's stressful security, the madding crowd and the scrum at boarding, where people and their myriad belongings clog the gate area, standing between you and your departure.
Curtin University scientists have modelled the effects of droplet size and velocity on evaporation to better understand the refining process of heavy oil.

Biologists have succeeded for the first time in describing the complex relationships within an ecosystem in unprecedented detail. Their model ecosystem was a “biological wastewater treatment plant”. In it live numerous species of bacteria which are involved in the wastewater purification process.
(Phys.org) —A pair of researches with Kyoto University has found how the queen of one species of termite, Reticulitermes speratus, ensures her genetic lineage continues by creating duplicate copies of herself. In their paper published in Proceedings of the National Academy of Sciences, Toshihisa Yashiro and Kenji Matsuura describe the study they carried out that showed how queens in such colonies reproduce themselves.
Bernard Bigot, the next director-general of ITER, plans to reform the decentralized structure of the project.

New biological methods used to trace the evolutionary history of kinship patterns shed new light on how societies developed as farming spread across the globe during the Neolithic, according to new research by a UCL-led international team.
(Phys.org) —A palaeontologist from our University studying fossils that were kept in a museum in Canada for over 75 years has discovered a new species of dinosaur.
The neocortex is the part of the brain that enables us to speak, dream, or think. The underlying mechanism that led to the expansion of this brain region during evolution, however, is not yet understood. A research team headed by Wieland Huttner, director at the Max Planck Institute of Molecular Cell Biology and Genetics, now reports an important finding that paves the way for further research on brain evolution: The researchers analyzed the gyrencephaly index, indicating the degree of cortical folding, of 100 mammalian brains and identified a threshold value that separates mammalian species into two distinct groups: Those above the threshold have highly folded brains, whereas those below it have only slightly folded or unfolded brains. The research team also found that differences in cortical folding did not evolve linearly across species.
Bioengineers at the University of California, San Diego have discovered that mouse embryos are contemplating their cellular fates in the earliest stages after fertilization when the embryo has only two to four cells, a discovery that could upend the scientific consensus about when embryonic cells begin differentiating into cell types. Their research, which used single-cell RNA sequencing to look at every gene in the mouse genome, was published recently in the journal Genome Research. In addition, this group published a paper on analysis of "time-course"single-cell data which is taken at precise stages of embryonic development in the journal of Proceedings of the National Academy of Sciences.
The new wonder material graphene has fantastic properties, for example flexibility, transparency and high charge carrier mobility. A study by an international team led by David Barbero, assistant professor and group leader at Umeå University, shows that semiconducting polymers placed on a layer of graphene transports electrical charge more efficiently than when placed on a substrate of silicon.
By solving a six-dimensional equation that had previously stymied researchers, University of Nebraska-Lincoln physicists have pinpointed the characteristics of a laser pulse that yields electron behavior they can predict and essentially control.
NGC 3532 is a bright open cluster located some 1300 light-years away in the constellation of Carina(The Keel of the ship Argo). It is informally known as the Wishing Well Cluster, as it resembles scattered silver coins which have been dropped into a well. It is also referred to as the Football Cluster, although how appropriate this is depends on which side of the Atlantic you live. It acquired the name because of its oval shape, which citizens of rugby-playing nations might see as resembling a rugby ball.
