Sexuella övergrepp kan ligga bakom tandvårdsrädsla3h
Tandvårdsrädsla kan ibland bero på tidigare sexuella övergrepp. Genom att vara uppmärksamma på signaler och fråga har tandvården möjlighet att hjälpa sina patienter. Det kan göras genom att lotsa dem vidare till professionell hjälp. Samtidigt är det också viktigt att bygga upp ett förtroende mellan tandläkare och patient och skapa en vårdsituation som upplevs som mindre hotfull.
Metaller som försvinner3h
Brutna ben måste fixeras för att läka rätt. En del kan gipsas medan andra behöver fästas med skruvar och plattor. Skruvar som ibland måste opereras bort efter att benet har läkt.

Menar vi samma saker?3h
För att forskare och vårdpersonal runt om i världen ska kunna jämföra patienter, tillstånd och behandlingar behövs gemensamma klassificeringar. Bildligt talat kan man inte jämföra äpplen med päron – om man tänkt att man ska jämföra just päron med päron. Smärta i ansiktet berör flera olika specialiteter inom tand- och sjukvård och 2019 publicerades ett gemensamt klassifikationssystem.
Röntgendiagnostik med kraftigt minskad stråldos3h
Den röntgen som kallas Cone Beam Computed Tomography (CBCT) har blivit allt vanligare för dentalt bruk eftersom den kan bidra med mer diagnostisk viktig information än vad konventionell röntgenundersökning kan.

Quantum systems are considered extremely fragile. Even the smallest interactions with the environment can result in the loss of sensitive quantum effects. In the renowned journal Science, however, researchers from TU Delft, RWTH Aachen University and Forschungszentrum Jülich now present an experiment in which a quantum system consisting of two coupled atoms behaves surprisingly stable.
Seabirds face dire threats from climate change, human activity — especially in Northern Hemisphere19h
Many seabirds in the Northern Hemisphere are struggling to breed — and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 28 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.
Seabirds' success reveals asymmetry in ocean health19h
In a study that uniquely evaluates marine ecosystem responses to a changing climate by hemisphere, researchers report that the fish-eating, surface-foraging bird species of the Northern Hemisphere suffered greater breeding productivity stresses over the last half-century than their Southern Hemisphere counterparts.
Seabirds sound alarm: Breeding success corresponds to hemispheric rates of ocean warming19h
Some seabirds are struggling to raise young where the globe is most rapidly warming – in the northern hemisphere, according to a study published in the journal Science. The research was undertaken by an international team of 40 scientists led by Farallon Institute in California.
Reducing metabolic cost of walking while generating electricity using an exoskeleton19h
An exoskeleton can reduce the metabolic cost of walking not by adding energy or by recycling energy from one gait phase to another, as other exoskeletons have done, but by removing the kinetic energy of a striding person's swinging leg so they don't have to tense their muscles so much.
Local management crucial to helping coral reefs survive warming waters19h
Local management of coral reefs to ease environmental stressors, such as overfishing or pollution, could increase reefs' chances of recovery after devastating coral bleaching events caused by climate change, a new study finds.
DNA vaccines for COVID-19 effective in mice, hamsters19h
Currently available COVID-19 vaccines rely on mRNA strands to teach the human immune system to recognize the SARS-CoV-2 virus. Now, researchers reporting in PLOS Neglected Tropical Diseases have reported the successful development of a vaccine that instead uses DNA encoding the virus' spike protein.

Dynamic remodeling of host membranes by self-organizing bacterial effectors19h
During infection, intracellular bacterial pathogens translocate a variety of effectors into host cells that modify host membrane trafficking for their benefit. We found a self-organizing system consisting of a bacterial phosphoinositide kinase and its opposing phosphatase that formed spatiotemporal patterns, including traveling waves, to remodel host cellular membranes. The Legionella effector Ma
Noncanonical crRNAs derived from host transcripts enable multiplexable RNA detection by Cas919h
CRISPR-Cas systems recognize foreign genetic material using CRISPR RNAs (crRNAs). In type II systems, a trans-activating crRNA (tracrRNA) hybridizes to crRNAs to drive their processing and utilization by Cas9. While analyzing Cas9-RNA complexes from Campylobacter jejuni , we discovered tracrRNA hybridizing to cellular RNAs, leading to formation of "noncanonical" crRNAs capable of guiding DNA targ
Quantum walks on a programmable two-dimensional 62-qubit superconducting processor•19h
Quantum Summit 2021
Quantum walks are the quantum mechanical analog of classical random walks and an extremely powerful tool in quantum simulations, quantum search algorithms, and even for universal quantum computing. In our work, we have designed and fabricated an 8-by-8 two-dimensional square superconducting qubit array composed of 62 functional qubits. We used this device to demonstrate high-fidelity single- and
Role of the ionic environment in enhancing the activity of reacting molecules in zeolite pores19h
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 walking19h
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 imprint19h
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 scattering19h
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 biosynthesis19h
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-tuning19h
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 heatwaves19h
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 sentinels19h
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 type19h
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 surveillance19h
