An international team of researchers led out of Macquarie University has demonstrated a new approach for converting ordinary laser light into genuine quantum light.

Talga Resources has revealed new test results on the ongoing optimization of its graphene silicon Li-ion battery anode product, Talnode™- Si. According to Talga, the battery anode product returns further performance gains, now delivering ~70% more energy density than commercial graphite-only anodes.

The product reportedly provides a “drop in” solution for improving current Li-ion battery performance. Commercial samples under confidentiality and material transfer agreements are scheduled to commence delivery around the end of February 2019 — recipients are said to include some of the world’s largest electronic corporations.

One way to crack this problem, according to the authors of a Perspective in this issue, is through a hybrid approach. The latest techniques in deep learning should be accompanied by a hand-in-glove pursuit of conventional physical modelling to help to overcome otherwise intractable problems such as simulating the particle-formation processes that govern cloud convection. The hybrid approach makes the most of well-understood physical principles such as fluid dynamics, incorporating deep learning where physical processes cannot yet be adequately resolved.

Studies of complex climate and ocean systems could gain from a hybrid between artificial intelligence and physical modelling.

From cancer research to designing systems powering the Eiffel Tower, the unsung scientists, inventors and entrepreneurs found in the new book ‘Hammer and Silicon’ make an impact.

The publication record of health-care start-up companies doesn’t seem to matter to investors, according to an analysis of nearly 50 biomedical ‘unicorns’ — venture-capital-backed companies valued at more than US$1 billion. The analysis, led by health-policy researcher John Ioannidis at Stanford University in California, finds no correlation between a company’s market valuation and its publication record — defined as the number of peer-reviewed papers authored directly by a firm. That’s a cause for concern, the authors say.

Firms can achieve fêted ‘unicorn’ valuations without publishing much peer-reviewed science. Health-care start-ups can reach billion-dollar valuations without publishing in peer-reviewed journals, but skipping that step can catch them out.

Taking regular breaks to refresh the mind is important during tough working days. Although surfing the web and swiping your phone to check updates on social media might be frowned upon, it could be more productive than you think.

The popularity of social media has exploded since Twitter launched just over a decade ago, and the platform has distinguished itself as the place to disseminate tightly packed information with immediacy. Academics have jumped on the bandwagon for a range of practical purposes.

The social-media platform is often a tool for procrastination, says Jet-Sing M. Lee. But what else can it be? The social-media platform is often a tool for procrastination, says Jet-Sing M. Lee. But what else can it be?

The Salt Honey bees deal with many stressors: chemicals, climate change and viruses. But this year, a tiny mite has wiped out colonies, causing worry over whether there are enough bees left to do their jobs.

The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs.

According to a new study led by researchers at the University of Birmingham and involving an international team of collaborators, the number of species within ecological communities on land has increased only sporadically through geological time, with rapid increases in diversity being followed by plateaus lasting tens of millions of years.

Previously, many scientists have argued that diversity increased steadily through geological time, which would mean that biodiversity today is much greater than it was tens of millions of years ago. But building an accurate picture of how land diversity was assembled is challenging because the fossil record generally becomes less complete further back in time. By using modern computing techniques, capable of analysing hundreds of thousands of fossils, patterns are starting to emerge that challenge this view.
