It has long been known that graphene has excellent electronic properties. However, it was unclear until now how stable these properties are. Are they destroyed by disturbances and additional effects, which are unavoidable in practice, or do they remain intact? Scientists have now succeeded in developing a comprehensive computer model of realistic graphene structures. It turned out that the desired effects are very stable. Even graphene pieces that are not quite perfect can be used well for technological applications.

A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication applications. A team stacked two different, atomically thin materials to realize this chiral quantum light source.

By some estimates, the human nose can detect up to a trillion different smells with its hundreds of scent receptors. But even just catching a quick whiff of certain chemicals known as nerve agents can be lethal, even in tiny amounts. Researchers have now developed a sensitive and selective nerve gas sensor using these human scent receptors. It reliably detected a substitute for deadly sarin gas in simulated tests.

Transparent and flexible displays, which have received a lot of attention in various fields including automobile displays, bio-healthcare, military, and fashion, are in fact known to break easily when experiencing small deformations. To solve this problem, active research is being conducted on many transparent and flexible conductive materials such as carbon nanotubes, graphene, silver nanowires, and conductive polymers.

Researchers report that it is possible to imbue graphite -- the bulk, 3D material found in No. 2 pencils -- with physical properties similar to graphite's 2D counterpart, graphene. Not only was this breakthrough unexpected, the team also believes its approach could be used to test whether similar types of bulk materials can also take on 2D-like properties. If so, 2D sheets won't be the only source for scientists to fuel technological revolutions. Bulk, 3D materials could be just as useful.

Researchers have developed a light-emitting electrochemical cell using dendrimers, a material gaining popularity in the industry. Moreover, the team found that using biomass derived cellulose acetate as the electrolyte retains the cell's long-life span. Combined with a graphene electrode, the cell has the potential to light the way for a future of eco-friendly and flexible light-emitting devices.

Researchers have used materials inspired by molecular gastronomy to create smart wearables that surpassed similar devices in terms of strain sensitivity. They integrated graphene into seaweed to create nanocomposite microcapsules for highly tunable and sustainable epidermal electronics. When assembled into networks, the tiny capsules can record muscular, breathing, pulse, and blood pressure measurements in real-time with ultrahigh precision.

Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark study has shown.

How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.

Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.

More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.
