When everyone is scoring and having fun out there, it makes the game so much better. You don't mind waking up and going to work. You don't mind practicing. You don't mind shootaround because everything is fun." Although the nucleus was relatively new, friendships were being formed off...
In this review we briefly summarize the principles of nucleocytoplasmic transport, and then describe the diverse strategies used by viruses to deliver their genomes into the host nucleus. Some of the emerging mechanisms include: (1) nuclear entry during mitosis, when the nuclear envelope is ...
Earlier scientists had demonstrated that atoms consist of positively charged nuclei surrounded by electrons orbiting like planets, but they couldn't explain why electrons didn't simply spiral into the nucleus. In 1913, Bohr proposed that electrons exist in discrete orbits based on their energy. When...
While circling the same atom's nucleus their trajectories invariably overlap. In my mind, the college campus served as that nucleus. With this knowledge, I could stand back and watch a shell route collision moment form. For instance, I was interested in a young man and would set my sights...
We're learning more about the craving that fuels self-defeating habits—and how new discoveries can help us kick the habit.
There’s always money in the grocery store dumpster. Gold suspected that the paraventricular hypothalamic nucleus (PVH), a tiny patch of roughly 50,000 neurons in the hypothalamus, played a role in controlling appetite. By today’s standards, the tools to study it back then were “stone age...
When large atoms split into one or more smaller atoms, giving off other particles and energy in the process, we call it nuclear fission. That's because the central part of the atom (the nucleus) is what breaks up and fission is another word for splitting apart. Nuclear fission can happen...
A nucleotide is the basic building block of nucleic acids (RNA and DNA). HowStuffWorks DNA is one of the nucleic acids, information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nucleic acid). DNA is found in the nucleus of every human cell. The information in...
When it eventually falls back down to its original level (closer to the nucleus), it releases some of its energy in the form of light photons. A glow stick does the same basic thing, but it uses a chemical reaction to excite the atoms. The Chemical Reaction Light sticks come in a ...
This can erase epigenetic memory and alter the identity of the donor nucleus. H3.3 A variant of histone H3, which is expressed throughout the cell cycle and is incorporated into chromatin independently of replication, for example at sites of active transcription. H3.3 and H3 differ by only ...
