As the Trump administration systematically defunds the American research ecosystem, while disingenuously promising a return to so-called "gold standard science," hope can be drawn from the new bipartisan initiative from Senators Martin Hein...
Reactivation of mammalian regeneration by turning on an evolutionarily disabled genetic switch [0.03%]
通过开启一个进化中丧失的遗传开关重新激活哺乳动物的再生能力

Urea is a key molecule in the search for the origin of life and a basic chemical produced in large quantities by industry. Its formation from ammonia and carbon dioxide requires either high pressures and temperatures or, under milder condit...
Rapid polygenic adaptation in a wild population of ash trees under a novel fungal epidemic [0.03%]
欧洲Ash树在新型真菌流行病下的快速多基因适应性演化

Carey L Metheringham et al.
Rapid evolution through small shifts in allele frequencies at thousands of loci is a long-standing neo-Darwinian prediction but is hard to characterize in the wild. European ash tree (Fraxinus excelsior) populations have recently come under...
Accelerated discovery of stable, extra-large-pore nano zeolites with micro-electron diffraction [0.03%]
