Using a novel molecular-data-storage technique, researchers have encoded a quote from Jane Austen's classic novel Mansfield Park in a series of oligomers, which a third party could read back without prior knowledge of the structures that encoded the passage.
Ever wondered why your virtual home assistant doesn't understand your questions? Or why your navigation app took you on the side street instead of the highway? Researchers have now designed a robot that 'thinks out loud' so that users can hear its thought process and better understand the robot's motivations and decisions.
Using satellite photos of three cities and drawing upon methods used to manipulate video and audio files, a team of researchers set out to identify new ways of detecting fake satellite photos and warn of the dangers of falsified geospatial data.
Plastics are ubiquitous, but they're not practical. Less than 10% are recycled, and the other approximately 8 billion tons are creating a pollution crisis. Researchers are determined to change that. A new analysis shows producing and recycling their game-changing new plastic could be easy and cheap enough to leave old plastics in the dust.
Using ALMA, astronomers found a rotating baby galaxy 1/100th the size of the Milky Way at a time when the Universe was only seven percent of its present age. Thanks to assistance by the gravitational lens effect, the team was able to explore for the first time the nature of small and dark 'normal galaxies' in the early Universe, which greatly advances our understanding of the initial phase of galaxy evolution.
It's a common sight: pelicans gliding along the waves, right by the shore. These birds make this kind of surfing look effortless, but actually the physics involved that give them a big boost are not simple. Researchers have recently developed a theoretical model that describes how the ocean, the wind and the birds in flight interact.
Researchers have found that artificial intelligence algorithms can influence people's preferences for fictitious political candidates or potential romantic partners, depending on whether recommendations were explicit or covert.
When air quality in China is poor, locally reported air pollution measurements diverge from U.S. embassy-reported measurements more than would be expected by random chance, finds an analysis of air pollution data from five large Chinese cities.
Categorization is the brain's tool to organize nearly everything we encounter in our daily lives. Grouping information into categories simplifies our complex world and helps us to react quickly and effectively to new experiences. Scientists have now shown that also mice categorize surprisingly well. The researchers identified neurons encoding learned categories and thereby demonstrated how abstract information is represented at the neuronal level.
An international study reveals the composition of the tropical forests of Central Africa and their vulnerability to the increased pressure from climate change and human activity expected in the coming decades. Thanks to an exceptional dataset - an inventory of over 6 million trees across five countries - the researchers have produced the first continuous maps of the floristic and functional composition of these forests, allowing them to identify the most vulnerable areas.
Wildfire smoke can trigger a host of respiratory and cardiovascular symptoms, ranging from runny nose and cough to a potentially life-threatening heart attack or stroke. A new study suggests that the dangers posed by wildfire smoke may also extend to the largest organ in the human body, and our first line of defense against outside threat: the skin.
A new study reports that the social cost of methane - a greenhouse gas that is 30 times as potent as carbon dioxide in its ability to trap heat - varies by as much as an order of magnitude between industrialized and developing regions of the world.
Nucleotide-binding, leucine-rich repeat receptors (NLRs) perceive pathogen effectors to trigger plant immunity. Biochemical mechanisms underlying plant NLR activation have until now remained poorly understood. We reconstituted an active complex containing the Arabidopsis coiled-coil NLR ZAR1, the pseudokinase RKS1, uridylated protein kinase PBL2, and 2'-deoxyadenosine 5'-triphosphate (dATP), demonstrating the oligomerization of the complex during immune activation. The cryo-electron microscopy structure reveals a wheel-like pentameric ZAR1 resistosome. Besides the nucleotide-binding domain, the coiled-coil domain of ZAR1 also contributes to resistosome pentamerization by forming an α-helical barrel that interacts with the leucine-rich repeat and winged-helix domains. Structural remodeling and fold switching during activation release the very N-terminal amphipathic α helix of ZAR1 to form a funnel-shaped structure that is required for the plasma membrane association, cell death triggering, and disease resistance, offering clues to the biochemical function of a plant resistosome.
