Why one of the brightest stars in the sky mysteriously began to darken

Astronomers may have solved the mystery of Betelgeuse’s strange decline in brightness. In the fall of 2019 Betelgeuse – one of the brightest and most famous stars in the sky – began to darken dramatically. By February 2020, it had lost about two-thirds of its normal luminosity. Betelgeuse, which forms the shoulder of constellation Orion (The Hunter) is an inflated …

How cells use “garbage bags” to transport their waste for recycling

Findings can have important implications for understanding age-related diseases. Scientists at Sanford Burnham Prebys have gained a deeper understanding of the intricacies of autophagy, the process by which cells break down and recycle cellular components. The findings published in Current biology, describe how the ‘garbage bags’ in a cage – called autophagosomes – are marked to direct their movement to …

They are considered to be the largest terrestrial mammal that ever lived, but their evolutionary history and scattering in Asia leave scientists confused. Paleontologists have now found fossils of a new, sixth species of the extinct giant rhinoceros, Paraceratherium linxiaense, which shed light on how …

Solving a long-standing biological mystery: How cells are measured

VIEW: The image shows the apical meristem of the shoot (in the center) with floral buds emerging on its flanks. Cells marked in green are about to replicate DNA, while the purple marker indicates an accumulation of KRP4, which is part of the mechanism that regulates cell size.
