Immunologist Troy Torgerson shares insights on research in the time of coronavirus, why the immune system is so fascinating, and the largest mysteries of human health and disease
Rachel TompaI love hearing scientists' perspectives that I wouldn't have thought about. When I asked @AllenInstitute immunologist Troy Torgerson about #COVID19, he said it makes him appreciate how remarkable the human immune system is, when it works.
Brain wiring asymmetry established as animals grow influences their innate behavior, a new study finds
Rachel TompaThis fascinating study led by @bassemh1 packs in so much: free choice, a bizarre experiment named after a 14th century philosopher, a fruit fly personality test, the randomness of biology -- and of course pretty pictures of colorful neurons.
Study finds human von Economo neurons’ closest cellular cousins and captures first electrical recordings from these large spindle-shaped brain cells.
Rachel TompaA few years ago, a woman underwent surgery for a brain tumor. The tissue sample she donated to @AllenInstitute turned out to contain a rare type of neuron, the von Economo neuron, never before studied while it was still alive & firing.
Endorphins and other neuropeptides vary widely between brain cell types and point to new possible targets for psychiatric drugs, study finds
Rachel TompaEndorphins and other neuropeptides are more widespread -- and more diverse -- across the brain than scientists previously understood, a new @AllenInstitute study published in @eLife has found.
The app, now on display at Pacific Science Center, teaches users the stages of cell division through interactions with 3D models of human cells.
Rachel TompaThis VR game made by @AllenInstitute developers, on display @PacSci, lets users hold, rotate, juggle & toss 3D models of human cells to learn the stages of cell division. It's called miTOSSis.
‘Rosehip’ neurons not found in rodents, may be involved in fine-level control between regions of the human brain
Rachel TompaA new type of human neuron discovered that doesn't appear to exist in rodents, in a new study @AllenInstitute & U of Szeged. The Szeged researchers call it a 'rosehip' neuron -- it looks to them like a rose that has lost all its petals.
Collaboration with Amazon Web Services brings 40 TB brain science dataset to the cloud
Rachel TompaWhat happens when a research team @AllenInstitute dedicated to #OpenScience generates a dataset that's simply too massive to share? Step 1: Try mailing hard drives. Step 2: Put it on the cloud, thanks to a new collaboration w/ @awscloud.
'Exceptional viability' of human neurosurgical samples could lay the groundwork for testing new gene therapies
Rachel TompaScientists @AllenInstitute are genetically labeling living *human* brain cells donated by surgical patients -- thanks to discovery that the tissue can live for up to 3 days on the lab bench. Wild!
A new study has found that the midpoints of our chromosomes seem to be marked with unusual X-shaped DNA -- and the Y chromosome is even more unusual.
Rachel TompaThe human Y chromosome is weird. Turns out its #centromere is also more 'monkey-like' than the rest of our chromosomes, at least in how its DNA is shaped. My latest for @fredhutch on a new Henikoff lab study
A new study using mice and tiny transparent fish as models of human cancer, published in Developmental Cell, has shed light on the very first stages of metastasis in the skin cancer melanoma.
Rachel TompaMacrophages spill their guts to help #melanoma spread, new @fredhutch study using tiny zebrafish to study the thorny problem of #metastasis. Beautiful images by Minna Roh-Johnson of a scary process.
When it comes to the flu, a few infected people may speak for the multitude. Evolutionary biologists have found that evolution in individual infections has parallels to the virus's later global evolution.
