Angle-dependent holograms made possible by metasurfaces
Recently, a research team from Pohang University of Science and Technology (POSTECH) has employed metasurfaces to fabricate angle-dependent holograms with multiple functions. This technology allows holograms to display multiple images based on the ob.....»»
How inter-annual climate variability affects seedling survival in temperate forests
Two new studies by researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences have revealed the relative effects of interannual climate variability and density-dependent species interactions on seedling survival in temperate.....»»
Research finds climate-dependent dispersal limitation plays an important role in mountain soil microbiome
Microbial communities are highly diverse, yet the mechanisms underlying microbial community assembly are not well understood. In 1967, Daniel Janzen hypothesized that low climatic variability along elevational gradients results in greater constraints.....»»
Viruses as important factors driving the diel dynamics of marine bacterioplankton
The diel cycle is one of the most common periodic patterns in marine ecosystems. Previously, the diel rhythm changes of marine bacterioplankton have often been attributed to factors like bacterial light-dependent physiological mechanisms or their int.....»»
The holographic secret of black holes

Five major outcomes from the latest UN climate summit
The latest UN climate summit, COP28, was always going to be controversial. It was held in a state whose economy is heavily dependent on oil and gas—the United Arab Emirates. The summit president, Sultan Al Jaber, remains head of the Abu Dhabi Natio.....»»
How to solve Sarentu Totems in Avatar: Frontiers of Pandora
Sarentu Totems are ancient, mysterious structures that need to be viewed from a specific angle in Avatar: Frontiers of Pandora. Here's how to find that spot......»»
Volumetric LED candle looks the same from any angle—and looks like amazing work
Re-creating a candle's multi-angle glow requires a lot of small-scale soldering. Enlarge / It takes proficiency in quite a few disciplines, a pick-and-place machine, a 3D printer, and lots of little solder points to get a candle.....»»
New approach to drug discovery: Developing pain medication with fewer side effects
People with chronic pain are often dependent on drugs from the class of opioids with sometimes considerable side effects. Accordingly, in recent years the search for safer alternatives has been the focus of new drug discovery......»»
More is not always better, even when it comes to digital platforms
As with the business of logistics, where having multiple routes to deliver goods to the same destination raises reliability, network-dependent consumerism depends on multiple networks having a host computer with multiple connections operating in sync.....»»
Low-pH-dependent RNA binding and oligomerization of SID-1 transmembrane family proteins: Implications for RNA transport
In C. elegans, the protein SID1 plays a crucial role in the systemic RNA interference process by facilitating the transport of exogenous double-stranded RNA into the cytoplasm. Previously, Chen-Yu Zhang's group has already demonstrated that intact pl.....»»
Apple faces lawsuit over high transfer fees between mobile wallets
Apple is the target of a new class action lawsuit filed by Venmo and Cash App customers over high transfer fees between mobile wallets. There’s also a cryptocurrency angle, because why not? more….....»»

Anisotropic lattice induces high-Q chiroptical responses in surface lattice resonance metasurfaces
Chirality is an intrinsic property of an object that cannot coincide with its mirror image by translation or rotation. In order to realize strong chiral light-matter interactions which are usually weak in natural materials for practical applications,.....»»
Finding the genes that help kingfishers dive without hurting their brains
If you've ever belly-flopped into a pool, then you know: water can be surprisingly hard if you hit it at the wrong angle. But many species of kingfishers dive headfirst into water to catch their fishy prey. In a new study in the journal Communication.....»»
Why a "hologram revolution" could be on the way
Holograms are getting better and cheaper and some think soon they will be everywhere......»»
