Principal Investigator(s): Siva A. Vanapalli, Texas Tech University Overview: This investigation uses roundworms to understand how microgravity changes the trillions of microbes living inside hosts and how those changes may affect health. Roundworms are ideal for this research because they share key genetic and biological similarities with humans. Microscopy image of C. elegans showing tail nerveContinue Reading
Forests cover more than 40 per cent of Belarus. At the same time, the country recorded twice as many forest fires last year compared to the year before.Continue Reading
After two centuries of failed attempts, scientists have finally grown dolomite in the lab, cracking a long-standing geological puzzle. They discovered that the mineral’s growth stalls because of tiny defects—but in nature, those flaws get washed away over time. By mimicking this process with precise simulations and electron beam pulses,Continue Reading
