The universe's first stars were extremely hot and incredibly large, often reaching hundreds of times the mass of the Sun. And because they formed just a few hundred million years after the Big Bang, these boiling behemoths contained virtually no elements heavier than hydrogen and helium, which were the only materials readily available at the time. But due to their sizeable stature, the first stars
Wildfires can have dramatic impacts on Western landscapes and communities, but human values determine whether the changes caused by fire are desired or dreaded. This is the simple – but often overlooked – message from a collaborative team of 23 researchers led by University of Montana faculty in a study published in the May issue of the journal BioScience.
Strongly correlated materials can change their resistivity from infinity to zero with minute changes in conditions. Now, researchers have fabricated a flexible organic 'correlated' transistor that makes it possible to control the effective pressure and doping level by bending the substrate and changing the gate voltage, respectively. This device allows researchers to switch superconductivity on an

And this royal baby co
Shakespeare, despite being perhaps the best-known writer in the English language, is a tricky figure to pin down. A new film about the playwright and poet's life offers just one of many fictional interpretations of his biography. Meanwhile, a heated scholarly debate ( two sides of which were featured in The Atlantic 's October 1991 issue ) over Shakespeare's identity has taken a fascinating femin
How do you tell the story of the world's greatest literary career when the literary part is a gaping hole, "a jigsaw puzzle for which most of the pieces are missing," as one scholar put it ? You get inventive, to put it charitably. All Is True , a new film directed by and starring Kenneth Branagh, is the latest installment in a long line of highly creative Shakespeare portraiture. In his novel No

Spin-orbit torque (SOT) offers promising approaches to developing energy-efficient memory devices by electric switching of magnetization. Compared to other SOT materials, metallic antiferromagnet (AFM) potentially allows the control of SOT through its magnetic structure. Here, combining the results from neutron diffraction and spin-torque ferromagnetic resonance experiments, we show that the magn
Upcoming advancements in flexible technology require mechanically compliant dielectric materials. Current dielectrics have either high dielectric constant, K (e.g., metal oxides) or good flexibility (e.g., polymers). Here, we achieve a golden mean of these properties and obtain a lightweight, viscoelastic, high-K dielectric material by combining two nonpolar, brittle constituents, namely, sulfur
As a stable and accurate biomarker, glycated hemoglobin (HbA1c) is clinically used to diagnose diabetes with a threshold of 6.5% among total hemoglobin (Hb). Current methods such as boronate affinity chromatography involve complex processing of large-volume blood samples. Moreover, these methods cannot measure HbA1c fraction at single–red blood cell (RBC) level, thus unable to separate the contri
Mechanical metamaterials exhibit unusual properties, such as negative Poisson's ratio, which are difficult to achieve in conventional materials. Rational design of mechanical metamaterials at the microscale is becoming popular partly because of the advance in three-dimensional printing technologies. However, incorporating movable building blocks inside solids, thereby enabling us to manipulate me
Generating time-correlated photon pairs at the nanoscale is a prerequisite to creating highly integrated optoelectronic circuits that perform quantum computing tasks based on heralded single photons. Here, we demonstrate fulfilling this requirement with a generic tip-surface metal junction. When the junction is luminescing under DC bias, inelastic tunneling events of single electrons produce a st
The triggered substitution of networks and their resulting functions play an important mechanism in biological transformations, such as intracellular metabolic pathways and cell differentiation. We describe the triggered, cyclic, reversible intersubstitution of three nucleic acid–based constitutional dynamic networks (CDNs) and the programmed catalytic functions guided by the interconverting CDNs
A Mott insulator sometimes induces unconventional superconductivity in its neighbors when doped and/or pressurized. Because the phase diagram should be strongly related to the microscopic mechanism of the superconductivity, it is important to obtain the global phase diagram surrounding the Mott insulating state. However, the parameter available for controlling the ground state of most Mott insula
Potassium-ion batteries (PIBs) have attracted tremendous attention due to their low cost, fast ionic conductivity in electrolyte, and high operating voltage. Research on PIBs is still in its infancy, however, and achieving a general understanding of the drawbacks of each component and proposing research strategies for overcoming these problems are crucial for the exploration of suitable electrode
The ultrafast response of metals to light is governed by intriguing nonequilibrium dynamics involving the interplay of excited electrons and phonons. The coupling between them leads to nonlinear diffusion behavior on ultrashort time scales. Here, we use scanning ultrafast thermomodulation microscopy to image the spatiotemporal hot-electron diffusion in thin gold films. By tracking local transient
Plasmonic metasurfaces are a promising route for flat panel display applications due to their full color gamut and high spatial resolution. However, this plasmonic coloration cannot be readily tuned and requires expensive lithographic techniques. Here, we present scalable electrically driven color-changing metasurfaces constructed using a bottom-up solution process that controls the crucial plasm

South Korean President Moon Jae In said he was building an "irreversible and lasting peace" on the Korean peninsula. What's become glaringly obvious, however, is that all this progress was as provisional as Kim
Between the shipping and handling, the web servers, the groceries, and the newspapers, Jeff Bezos never stopped thinking about the moon.

"And it hasn't changed." Bezos, in addition to leading Amazon and owning
Solar cells and photocathodes made of copper oxide could theoretically attain high efficiencies for solar energy conversion. In practice, however, large losses occur. Now, a team at the HZB has been able to use a sophisticated femtosecond laser experiment to determine where these losses take place—not so much at the interfaces, but instead, far more in the interior of the crystalline material.

What is the opposite of inspiration? I refer not to a simple lack of inspiration, mind you, but to a quality antithetical to ingenuity and originality. Whatever that quality is—I presume there must be a word for it in German— The Hustle is brimming with it. The movie is not merely uninspired, but sub-inspired, de-inspired, anti-inspired. It feels at times like the consummation of some wicked dare
Donald Trump is clearly spooked by Joe Biden —but some of the president's supporters say there's an easy solution: Make Biden out to be Hillary Clinton, just older and with a longer record of not getting things done in Washington.

Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
