Electrons flowing through power lines and computers inevitably encounter resistance; when they do, they lose some of their energy, which dissipates as heat. That's why laptops get hot after being used for too long and why MIT physicists and colleagues have discovered the "secret sauce" behind some of the exotic properties of a new quantum material that has transfixed physicists due to those properties, which include superconductivity.
Twisted nanoscale semiconductors manipulate light in a new way, researchers at the University of Bath and the University of Michigan have shown. The effect could be harnessed to accelerate the discovery and development of While the Large Hadron Collider LHC at CERN is well known for smashing protons together, it is actually the quarks and gluons inside the protons—collectively known as partons—that are really interacting.
Thus, in order The discovery of the Higgs boson was a landmark in the history of physics. It explained something fundamental: how elementary particles that have mass get their masses. But it also marked something no less fundamental: the Unfortunately, their efficiency peaks under low current densities. Quantum states of light have enabled novel optical sensing schemes, e. The field of quantum metrology The number of measurements needed to characterize a system of quantum particles is far fewer than previously thought, a RIKEN physicist and three collaborators have shown.
As well as cutting the workload of experimentalists, Researchers have developed a new, focus-free technique for creating chemical maps using X-ray fluorescence. The approach offers fast, high-resolution measurements, which could be useful for analyzing chemical composition FeSe, an iron-based superconductor, is an important prototype material to study the superconduction-related properties, and electron-phonon coupling EPC plays an important role in FeSe.
Pressure changes the structure of Scientists understand quite well how temperature affects electrical conductance in most everyday metals like copper or silver. Latest News. A new study shows that red supergiant stars can violently erupt before Meet a Colorful but Colorblind Spider Jan.
Researchers calculated how people To do so, they employed what is known as ternary Patients who have active immune responses against cancer cells tend An excessively sedentary lifestyle and a too-caloric diet encourage the development of this Scientists have developed a tiny version of a Hall To do so, they used water-vapor plasma to directly Researchers have identified a composite material that could integrate quantum devices into semiconductor The highly trained algorithm combed Physicists have devised an elegant experiment to answer this These may include devices that use quantum information as input and output Other factors, including genetics, also influence one's chance of developing multiple sclerosis.
A new animation of Earth shows vegetation taking up and releasing carbon in sync with the seasons. Scientists onboard an icebreaker in Antarctica were blown away when they spied a trove of 60 million icefish nests dotting the floor of the Weddell Sea. A telescope in Arizona modified to measure the true distance of galaxies has produced the largest three-dimensional map of the universe ever. A volunteer archaeologist discovered a stash of 41 "rainbow cup" Celtic coins dating to 2, years ago in Germany.
Astronomers mapped 12 stellar streams, which could lead to the Milky Way's missing dark matter. A new study into the Local Bubble, a cosmic void surrounding Earth, has mapped out the star-forming regions on the bubble's surface and uncovered more information about its explosive birth. It's difficult to predict what combination of traits such a variant might have.
An enormous asteroid more massive than two Empire State Buildings will zoom harmlessly past Earth next week.
