摘要：Strange metals-ubiquitous in correlated quantum materials-transport electrical charge at low temperatures but not by the individual electronic quasiparticle excitations, which carry charge in ordinary metals. In this work, we consider two-dimensional metals of fermions coupled to quantum critical scalars, the latter representing order parameters or fractionalized particles. We show that at low temperatures (T), such metals generically exhibit strange metal behavior with a T-linear resistivity ...

摘要：Magnetars are highly magnetized neutron stars, the formation mechanism of which is unknown. Hot helium-rich stars with spectra dominated by emission lines are known as Wolf-Rayet stars. We observed the binary system HD 45166 using spectropolarimetry and reanalyzed its orbit using archival data. We found that the system contains a Wolf-Rayet star with a mass of 2 solar masses and a magnetic field of 43 kilogauss. Stellar evolution calculations indicate that this component will explode as a supe...

摘要：It is imperative to understand the fate of crude oil that escapes into the ocean to minimize its environmental, economic, and societal harm. Large amounts of crude oil enter the sea, as occurred this past month on a platform in the Gulf of Mexico. Oil does not easily mix with water, which can restrict oil degradation through microbes, a key pathway to remove hydrocarbons from the environment. However, turbulent seas and response measures, such as dispersant addition, generate smaller oil dropl...

摘要：Protection of telomeres 1 (POT1) is the 3 ' single-stranded overhang-binding telomeric protein that prevents an ataxia telangiectasia and Rad3-related (ATR) DNA damage response (DDR) at chromosome ends. What precludes the DDR machinery from accessing the telomeric double-stranded-single-stranded junction is unknown. We demonstrate that human POT1 binds this junction by recognizing the phosphorylated 5 ' end of the chromosome. High-resolution crystallographic structures reveal that the junction...
