iPS cell-derived cardiac myocytes (heart muscle cells) typically beat about once per second, so I usually speed up the movies I post; otherwise, scrollers might miss the action. But every now and then, a cell looks like this in real time. Could we use these rare cells to uncover

The protein concentration in the cytoplasm is so high that the average protein has a water hydration shell of only ≈ 10 water molecules separating it from the adjacent protein hydration shell.

Neurons transmit signals through synaptic vesicle release, but the nanoscale dynamics of this process have been unclear. In a new Science study, researchers report using time-resolved cryo–electron tomography to visualize synaptic vesicle dynamics in situ and propose a unified

Momento idóneo para que la banca devuelva los más de 65.000 millones de euros que costó su rescate cuando gobernaba Rajoy ...

@Josepablo_ls La 2ª opción…

Finally got around to reading the "Ballistic Microscopy" paper, and it is really incredible. The paper opens with a compelling idea; one I hadn’t explicitly thought about before: “Light and electron microscopy utilizes interactions of either photons or electrons with matter to

A simple guide to how mitochondria work. 4️⃣ primar jobs Mitochondria are more than the “powerhouse of the cell.” They’re multitasking organelles that control energy, stress, genetics, and even cell survival. Here are the 4 primary jobs they do: 1️⃣ ATP Generation (Energy

We increasingly understand obesity as a brain-based disease. This review by Zagmutt et al., 2025 maps how subtle inflammation in the hypothalamus evolves over time offering a clearer picture of when and how metabolic regulation begins to fail. 1/5

In the spirit of #BlueSoup and my friend Elinne, I am sequencing the Triton X-100 contaminant. Stay tuned! Big thanks to @johnowhitaker for bankrolling the plasmidsaurus run. All data will be made public and strain sharable. Yay, community science!

Researchers in Science have uncovered a surprising role for cholesterol regulation in immune cells. By controlling T cell signaling, the cholesterol transporter protein Aster-A not only shapes immune responses but also influences how the body absorbs fat—protecting mice from

What is RNA velocity in situ? ChatGPT kept getting it wrong... So I made this video explaining how RNA velocity in situ infers gene expression dynamics by distinguishing nuclear vs. cytoplasmic expression in spatial transcriptomics data: https://t.co/IyvbNrZNBM #AcademicTwitter
