    This Blood Stem Cell Research Could Change Medicine of the Future

    Lead Image: The microfluidic device that emulated an embryo’s heartbeat and blood circulation. The cell seeding channels are indicated by red food dye, while the heart ventricular contraction control channels and circulation valve control channels are indicated by blue and green food dye respectively. Credit: Jingjing Li, UNSW Sydney New discoveries about embryonic blood stem cell creation made independently by biomedical engineers and medical researchers at the University of New South Wales (UNSW) Sydney could one day eliminate the need for blood stem cell donors. These achievements are part of a move in regenerative medicine towards the use of ‘induced…

    Listen to Space Rocks Crash Into Mars – Recorded by NASA’s InSight Lander

    Lead Image: NASA’s InSight lander has detected seismic waves from four space rocks that crashed on Mars. Credit: NASA/JPL-Caltech/University of Arizona NASA’s InSight “Hears” Its First Meteoroid Impacts on Mars SEIS, the Mars lander’s seismometer, has picked up vibrations from four separate impacts in the past two years. NASA’s InSight lander has detected seismic waves from four space rocks that crashed on Mars in 2020 and 2021. These represent the first impacts detected by the spacecraft’s seismometer since InSight touched down on the Red Planet in 2018. In fact, it also marks the first time seismic and acoustic waves from…

    The Earth’s Newest Secret: Fundamental Changes to What We Know About How Volcanoes Work

    Lead Image: Fagradalsfjall volcano in Iceland erupting at night. Recent discoveries from Iceland’s Fagradalsfjall eruptions alter what we know about how volcanoes work. Learning something that fundamentally changes how we understand our world doesn’t happen very often. But for University of California, Santa Barbara Earth scientist Matthew Jackson and the thousands of volcanologists across the globe, such a revelation has just occurred. While sampling magma from the Fagradalsfjall volcano in Iceland, Jackson and his colleagues uncovered a process far more dynamic than anyone had assumed in the two centuries that scientists have been studying volcanoes. “Just when I think we’ve…

    Using DNA To Convert Carbon Dioxide Into Valuable Products

    Chemical engineers at MIT are using DNA to help convert CO2 into valuable chemicals. MIT Assistant Professor Ariel Furst and her colleagues are looking to DNA to help guide the process. Carbon dioxide (CO2) is a significant product of many human activities, including industrial manufacturing. It is also a major contributor to climate change. Therefore, a major goal in the energy sector has been to chemically convert emitted CO2 into fuels or other valuable chemicals. Although CO2 is available in abundance, it has not yet been widely used to generate value-added products. Why not? One of the main reasons is…

    Scientists Thought a Bacteria Was Harmless – They Were Wrong

    Lead Image: Scientists have discovered that a type of bacteria is not as harmless as previously thought. It can actually cause infections in patients with bronchiectasis, asthma, and chronic obstructive pulmonary disease (COPD). An international study led by Singapore scientists discovers bacteria previously thought harmless can worsen existing lung disease. A team of international scientists has discovered that Neisseria — a genus of bacteria that lives in the human body – is not as harmless as previously thought. In fact, it can cause infections in patients with bronchiectasis, asthma, and chronic obstructive pulmonary disease (COPD). In a landmark study, published…
