A new study has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA’s Perseverance rover. The findings, published by a large international team of scientists, focus on a region of Jezero Crater known as the […]
Light can do remarkable things, but it has limitations. Ordinary photons are bound by diffraction, which sets a limit on how tightly they can be confined in space. This is why focusing light to spots smaller than about half its […]
Imagine a clock that doesn’t have electricity, but its hands and gears spin on their own for all eternity. In a new study, physicists at the University of Colorado Boulder have used liquid crystals, the same materials that are in […]

Researchers at Institute of Science Tokyo have created a new material platform for non-volatile memories using covalent organic frameworks (COFs), which are crystalline solids with high thermal stability. The researchers successfully installed electric-field-responsive dipolar rotors into COFs. Due to the […]
A new archaeological study , conducted along the Jordan River banks south of northern Israel’s Hula Valley, offers a fresh perspective on the dietary habits of early humans, challenging conventional wisdom about prehistoric diets. The research reveals that ancient hunter-gatherers […]
Scientists believe individuals of the most recently discovered hominin group (the Denisovans) that interbred with modern day humans passed on some of their genes via multiple, distinct interbreeding events that helped shape early human history. In 2010, the first draft […]
Author: Ari Koeppel, Postdoctoral Scientist in Earth and Planetary Science, Dartmouth College Andy Weir’s bestselling story “The Martian” predicts that by 2035 NASA will have landed humans on Mars three times, perfected return-to-Earth flight systems and collaborated with the China […]
In my past entry I commented on the problems that Angela Potochnik’s Idealization and the Aims of Science contains regarding her analysis of idealization. Now I will look at the question of truth. My main argument is that neither the […]
T-cell acute lymphoblastic leukemia (T-ALL) is characterized by the accumulation of genetic lesions that induce differentiation arrest, survival and aberrant proliferation of immature T-cell progenitors . Although T-ALL prognosis has significantly improved due to intensive chemotherapy, relapses still occur in […]
