will work? The new technique centres on a new way to interpret results
of Raman spectroscopy, a common, non-destructive process that
geologists use to identify chemical composition of ancient rocks. Among
its suite of scientific tools, the 2020 Mars rover includes SHERLOC, an
instrument that will acquire Raman spectra from samples on or just
below the Mar’s surface. SHERLOC will be pivotal in determining whether
life ever existed on Mars. Using it will be able to estimate the ratio of
hydrogen to carbon atoms from the substructure of the peaks in Raman
spectra.
Scientists successfully grow three-dimensional lungs in
lab using stem cells:
Scientists in the United States including those of Indian origin have
successfully grown three-dimensional (3D) lungs in the lab, using stem
cells. The 3D lungs or organoids was created by coating tiny gel beads
with lung-derived stem cells and then allowing them to self-assemble
into the shapes of the air sacs found in human lungs. To show that
these tiny organoids mimicked the structure of actual human lungs,
researchers compared it with real sections of human lung. Significance:
The laboratory-grown 3D lungs can be used to study diseases including
Idiopathic Pulmonary Fibrosis (IPF) which has been difficult to study
using conventional methods and also test possible treatments for the
lung diseases.
