Role of the ionic environment in enhancing the activity of reacting molecules in zeolite pores
Tailoring the molecular environment around catalytically active sites allows for the enhancement of catalytic reactivity through a hitherto unexplored pathway. In zeolites, the presence of water creates an ionic environment via the formation of hydrated hydronium ions and the negatively charged framework aluminum tetrahedra. The high density of cation-anion pairs determined by the aluminum concen

Removing energy with an exoskeleton reduces the metabolic cost of walking
Evolutionary pressures have led humans to walk in a highly efficient manner that conserves energy, making it difficult for exoskeletons to reduce the metabolic cost of walking. Despite the challenge, some exoskeletons have managed to lessen the metabolic expenditure of walking, either by adding or storing and returning energy. We show that the use of an exoskeleton that strategically removes kine

Control of polarization in bulk ferroelectrics by mechanical dislocation imprint
Defects are essential to engineering the properties of functional materials ranging from semiconductors and superconductors to ferroics. Whereas point defects have been widely exploited, dislocations are commonly viewed as problematic for functional materials and not as a microstructural tool. We developed a method for mechanically imprinting dislocation networks that favorably skew the domain st

Free coherent evolution of a coupled atomic spin system initialized by electron scattering
Full insight into the dynamics of a coupled quantum system depends on the ability to follow the effect of a local excitation in real-time. Here, we trace the free coherent evolution of a pair of coupled atomic spins by means of scanning tunneling microscopy. Rather than using microwave pulses, we use a direct-current pump-probe scheme to detect the local magnetization after a current-induced exci

Mitochondrial NADP(H) generation is essential for proline biosynthesis
The coenzyme nicotinamide adenine dinucleotide phosphate (NADP + ) and its reduced form (NADPH) regulate reductive metabolism in a subcellularly compartmentalized manner. Mitochondrial NADP(H) production depends on the phosphorylation of NAD(H) by NAD kinase 2 (NADK2). Deletion of NADK2 in human cell lines did not alter mitochondrial folate pathway activity, tricarboxylic acid cycle activity, or

Nematic quantum criticality in an Fe-based superconductor revealed by strain-tuning
Quantum criticality may be essential to understanding a wide range of exotic electronic behavior; however, conclusive evidence of quantum critical fluctuations has been elusive in many materials of current interest. An expected characteristic feature of quantum criticality is power-law behavior of thermodynamic quantities as a function of a nonthermal tuning parameter close to the quantum critica

Local conditions magnify coral loss after marine heatwaves
Climate change threatens coral reefs by causing heat stress events that lead to widespread coral bleaching and mortality. Given the global nature of these mass coral mortality events, recent studies argue that mitigating climate change is the only path to conserve coral reefs. Using a global analysis of 223 sites, we show that local stressors act synergistically with climate change to kill corals

Hemispheric asymmetry in ocean change and the productivity of ecosystem sentinels
Climate change and other human activities are causing profound effects on marine ecosystem productivity. We show that the breeding success of seabirds is tracking hemispheric differences in ocean warming and human impacts, with the strongest effects on fish-eating, surface-foraging species in the north. Hemispheric asymmetry suggests the need for ocean management at hemispheric scales. For the no

3D genomics across the tree of life reveals condensin II as a determinant of architecture type
We investigated genome folding across the eukaryotic tree of life. We find two types of three-dimensional (3D) genome architectures at the chromosome scale. Each type appears and disappears repeatedly during eukaryotic evolution. The type of genome architecture that an organism exhibits correlates with the absence of condensin II subunits. Moreover, condensin II depletion converts the architectur

Resurgence of SARS-CoV-2: Detection by community viral surveillance
Surveillance of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has mainly relied on case reporting, which is biased by health service performance, test availability, and test-seeking behaviors. We report a community-wide national representative surveillance program in England based on self-administered swab results from ~594,000 individuals tested for SARS-CoV-2, regard

Material-structure-performance integrated laser-metal additive manufacturing
Laser-metal additive manufacturing capabilities have advanced from single-material printing to multimaterial/multifunctional design and manufacturing. Material-structure-performance integrated additive manufacturing (MSPI-AM) represents a path toward the integral manufacturing of end-use components with innovative structures and multimaterial layouts to meet the increasing demand from industries

Multiscale representation of very large environments in the hippocampus of flying bats
Hippocampal place cells encode the animal's location. Place cells were traditionally studied in small environments, and nothing is known about large ethologically relevant spatial scales. We wirelessly recorded from hippocampal dorsal CA1 neurons of wild-born bats flying in a long tunnel (200 meters). The size of place fields ranged from 0.6 to 32 meters. Individual place cells exhibited multiple

Socioeconomic status determines COVID-19 incidence and related mortality in Santiago, Chile
The COVID-19 pandemic has affected cities particularly hard. Here, we provide an in-depth characterization of disease incidence and mortality and their dependence on demographic and socioeconomic strata in Santiago, a highly segregated city and the capital of Chile. Our analyses show a strong association between socioeconomic status and both COVID-19 outcomes and public health capacity. People li

Different neurons make hairy and hairless skin itch
Researchers have uncovered differences in itch in non-hairy versus hairy areas of the skin. The work could open new, more effective treatments for patients suffering from persistent skin itching. Chronic skin itching drives more people to the dermatologist than any other condition. In fact, the latest science literature finds that 7% of US adults, and between 10 and 20% of people in developed cou

Not fear, but goal importance and others' behavior makes you favour COVID-19 measures
Fear that you are at particularly lethal risk of COVID-19 infection might not be quite as strong of motivation to support strict government regulations and drastically change your lifestyle as your perception of whether others are doing enough to fight COVID-19, concludes a new study looking into data from the United Kingdom and Switzerland. The research paper is published in the peer-reviewed sci

Eating noises make you crazy? You have misophonia
Some people are driven absolutely bonkers when they hear other people eating or even breathing. Such people likely have a condition called "misophonia," or "hatred of sound." fMRI brain scans reveal a surprising cause for the condition. Maybe it's happened to you. You're sitting there quietly munching away on something, and suddenly, you feel someone's eyes burning into you. When you turn toward
