Sterols are among the most abundant lipids in eukaryotic cells, yet are synthesized through notoriously long, complex metabolic pathways. Researchers have used a novel approach to show how they ...

Taste, pain, or response to stress—nearly all essential functions in the human body are regulated by molecular switches ...

I meditate on Maha Saraswati who holds in her eight lotuslike hands bell trident plough conch mace discus bow and arrow who is effulgent like the moon shining at the fringe of a cloud she is the subst ...

NAVI MUMBAI: The divisional forest office of the mangroves cell submitted a report to the government confirming that the TS Chanakya, NRI area wetlands and DPS lake are water bodies. The City ...

Here, we use single-particle cryo-EM to determine the structures of four human ... Finally, we isolated individual tRNA iso-acceptors from human cells and determined their intermediate-resolution ...

Here, the authors study how this directionality is regulated. They show that inter-organ communication between the tracheal stem cells and the nearby fat body plays a role. They provide compelling ...

"We discovered aging triggers the arrival of a new type of adult stem cell and enhances the body's massive production of new fat cells, especially around the belly." In collaboration with the UCLA ...

The purpose of this package is to provide tools for rigid bodies with point-discretized surfaces. It currently includes methods for a library of 2D surface shape definitions and associated point ...

Ion velocity spectra in experiments and 1D PIC simulations. Credit: Hui-bo Tang et al. Key to the discovery were particle-in-cell simulations, which tracked ion trajectories and electromagnetic fields ...
