NASA’s Webb Telescope reveals twinkling scene unseen by Hubble
When the James Webb Space Telescope launched at the end of last year, astronomers have given it an infinite number of missions. I say infinite because ultimate goal of this engineering marvel…
Huge radiation storms have hit Earth for at least 10,000 years and could strike again, analysis of tree rings reveals
A series of sudden and colossal spikes in radiation levels across Earth’s history could stem from a series of unknown, unpredictable and potentially catastrophic cosmic events, a new study has revealed. Miyake…
Node-centric expression models (NCEM): graphical neural networks reveal communication between cells
Modeling ligand-receptor signaling with NCEM. (a) UMAP of cells in MERFISH-fetal liver data. (b) Imputation of MERFISH data with scRNA-seq increases the number of genes that can be modeled with NCEMs, including…
Traces of ancient oceans found on Mars
image: There has long been a debate in the scientific community about whether Mars had an ocean in its low-lying northern hemisphere. Using topographic data, a Penn State-led research team was able…
How to see the bigger picture from NASA’s Webb Space Telescope
MEMPHIS, Tenn. – Side-by-side images of NASA’s 32-year-old Hubble Space Telescope and the brand new James Webb Space Telescope may draw oohs and ahhs, but they don’t give you a full picture…
Do bees play? Groundbreaking study says yes.
Many animals love to play, often for no apparent reason other than fun. Pet owners know this to be true for cats, dogs, and even rodents, and scientists have observed the same…
