Deciphering the Mechanical Properties of Stem Cells Scientists at the Brown University, in the United States, say that they have recently made a significant discovery related to the mechanical properties of stem cells. After carefully analyzing these properties, the group found that the data could be used to predict the type of cell stem cells would differentiate into. Mesenchymal ... Seagrasses Are Better at Carbon Storage Than Forests According to the conclusions of a new scientific investigation published in this week's issue of the top journal Nature Geoscience, it would appear that seagrass meadows at the bottom of the sea can store up to twice as much carbon dioxide as the world's tropical and temperature forests (per unit area). In a paper entitled &ldquo... MAVEN Magnetometers Completed at GSFC Officials at the NASA Goddard Space Flight Center (GSFC), in Greenbelt, Maryland, announce the completion of two magnetometers that will go on the American space agency's Mars Atmosphere And Volatile EvolutioN (MAVEN) spacecraft. The purpose of the two flux gate magnetometers will be to measure the intensity of the magnetic field wherever the ... Cassini Sees Saturnine Moon Methone The NASA Cassini spacecraft has recently carried out a flyby of the small Saturnine moon Methone, as it was positioning itself for its last pass over the large moon Titan. The orbiter is currently getting ready to shift from an equatorial to a polar orbit, which will enable it to observe Saturn's poles in detail. This change implies that the veh... Europeans Set New Teleportation Record Chinese experts were able a few weeks back to set a new world record for the distance over which teleportation is possible. The Asian group announced that it managed to teleport data over a little less than 100 kilometers (60 miles), but now European researchers set a new record. A group of physicists was able to transfer the information stor... New Type of Resistive RAM Developed in the UK Researchers at the University College London (UCL), in the United Kingdom, announce the development of a Resistive RAM memory (ReRAM) chip made up entirely of pure silicon oxide. This achievement opens up a new avenue of research for creating super-fast computer memory chips, which would operate considerably faster than anything on the... Graphene to Replace Hexavalent Chromium as Steel Coating Rust is the worst enemy of many iron- and steel-based products, so coatings need to be used in order to protect them from corrosion. This is usually done with compounds containing a carcinogenic element called hexavalent chromium, but graphene may provide a safer, more efficient solution. Hexavalent chromium is a known carcin... Saturated Fats Intake Leads to Cognitive Decline According to the conclusions of a new study, it would appear that consuming a lot of saturated fats – such as found in fatty meats, lard, butter, cheese, cream, coconut oil and palm kernel oil, among other sources – leads to cognitive decline and memory impairment in humans. Investigators at the Brigham and Women’s... Massive Turtle Species Discovered in Colombia Experts from the University of Florida (UF) Florida Museum of Natural History (FMNH) announce the discovery of a giant turtle species that was previously unknown to science. The creature was discovered in the same mine that revealed the famous Titanoboa. The latter was the world's largest known snake, reaching lengths of between 12 to ... Advanced Ceramic Membrane for Carbon Capture Created Carbon capture and storage (CCS) have been under research for years, but their high costs have thus far prevented their widespread implementation. Now, a system created by experts in the US could make it easier for fossil fuel-powered electrical plants to reduce their emissions. Greenhouse gases have been demonstrated to cause gl... Mercury Pollution Found in the Arctic The Arctic Ocean and surrounding areas are polluted with mercury from a number of sources, scientists at the Harvard University School of Engineering and Applied Sciences (SEAS) found in a new study. The dangerous chemical is brought to the area by atmospheric forces such as winds, as well as by intricate river flow patterns in the Arctic regio... How Chemotherapy Boosts Bone Cancer Growth A team of experts at the University of Michigan School of Dentistry has recently discovered that administering chemotherapy drugs to people in the earliest stages of bone marrow cancer can actually have a very negative effect on their health. According to SD Department of Periodontics and Oral Medicine professor, Laurie McCauley, a drug u... Life Recovering 30 Years After Mount St. Helens Eruption Using data from the Landsat satellite constellation, experts at the American space agency have recently created a new time-lapse video of Mount St. Helens and the surrounding areas, showing how life recovered following the volcano's massive, May 18, 1980 eruption. The event saw the entire northern face of the mountain being d...
