摘要:Microscopic magnetic fields form in non-magnetic materials when light makes the atoms rotate. A similar macroscopic effect has long been known, but proof of its atomic equivalent could give rise to ultrafast data processing.

摘要:Shuotheriids are Jurassic mammaliaforms that possess pseudotribosphenic teeth in which a pseudotalonid is anterior to the trigonid in the lower molar, contrasting with the tribosphenic pattern of therian mammals (placentals, marsupials and kin) in which the talonid is posterior to the trigonid(1-4). The origin of the pseudotribosphenic teeth remains unclear, obscuring our perception of shuotheriid affinities and the early evolution of mammaliaforms(1,5-9). Here we report a new Jurassic shuothe...

摘要:Researchers from the global south face often-distressing immigration bureaucracy that most from the global north do not. Six steps can begin to counteract this inequity.

摘要:Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a bulk band gap similar to an ordinary insulator but have topologically protected pairs of edge modes of opposite chiralities(1,2,3,4,5,6). So far, experimental studies have found only integer QSH insulators with counter-propagating up-spins and down-spins at each edge leading to a quantized conductance G(0) = e(2)/h (with e and h denoting the electron charge and Planck's constant, respectively)(7,8,9,10,11,1...

摘要:Epstein-Barr virus (EBV) infection can engender severe B cell lymphoproliferative diseases1,2. The primary infection is often asymptomatic or causes infectious mononucleosis (IM), a self-limiting lymphoproliferative disorder3. Selective vulnerability to EBV has been reported in association with inherited mutations impairing T cell immunity to EBV4. Here we report biallelic loss-of-function variants in IL27RA that underlie an acute and severe primary EBV infection with a nevertheless favourable...

摘要:The emergence of collective order in matter is among the most fundamental and intriguing phenomena in physics. In recent years, the dynamical control and creation of novel ordered states of matter not accessible in thermodynamic equilibrium is receiving much attention(1-6). The theoretical concept of dynamical multiferroicity has been introduced to describe the emergence of magnetization due to time-dependent electric polarization in non-ferromagnetic materials(7,8). In simple terms, the coher...
