  • SCTIMST develops flow diverter stent to treat aneurysms
    Researchers from Sree Chitra Thirunal Institute of Medical Science and Technology (SCTIMST) developed an innovative intracranial flow diverter stent.

    The device is used for the treatment of aneurysms of the blood vessels of the brain. Aneurysms are the enlargement of an artery caused by weakness in the arterial wall.

    Flow Diverter Stent:
    The Flow Diverter Stent will divert blood flow away from the aneurysm when deployed in the artery in the brain bearing the aneurysms. It reduces the chances of its rupture from the pressure of blood flow.

    The stent has been designed to have a better grip on the walls of arteries of complex shapes in order to reduce the risk of migration of the device.

    The device has the advantages of being flexible and adaptable to the shape and course of the vessel.

    It promotes healing of the vessel wall by removing the constant stress of blood flow on it. The spontaneous rupture of the aneurysm might result in bleeding into the space around the brain, resulting in a condition called subarachnoid hemorrhage (SAH). It will lead to paralysis, coma or death.

    RaIDer-X was co-developed by the High Energy Materials Research Laboratory (HEMRL), Pune and Indian Institute of Science (IISc), Bangalore.

    The explosive detection device has the capability to detect explosives from a stand-off distance.

    The system can be modified to expand its capability to detect a number of explosives in pure form and with the contaminants and Bulk explosives in concealed conditions.

    The portable devices can now be safely and effectively used by security agencies.



  • Scientists found bacteria that can replace fertilizers, fungicides in tea plants
    Researchers at the Institute of Advanced Study in Science and Technology (IASST) Guwahati found significant plant-growth-promoting and antifungal activities of endophytic actino bacteria associated with Tea plant and related genera, Eurya.

    Highlights:
    They find potent plant growth-promoting strains.

    The study stated that the application of endophytic Actino bacteria could reduce chemical inputs in Tea plantation.

    The team isolated 46 endophytic actino bacteria found in diverse environments that live within a plant for at least part of its life cycle without causing apparent disease associated with Tea plants and characterized through molecular techniques.

    Out of 46 isolates, 21 isolates inhibited the growth of at least one test fungal phytopathogens and strains SA25 and SA29 exhibited broad-spectrum antifungal activity.

    The research confirmed that endophytic actino bacteria have the potential to exhibit multiple growth-promoting traits such as IAA production, phosphate solubilization, siderophore production and so on that positively influence tea growth and production.

    Tea:
    Tea (Camellia sinensis) plays an important role in the Indian economy as a major portion of the tea produced is exported.

    Due to higher demand for chemical residue-free made tea by the importing countries has led to a decline in the export of tea.

    The recent study attempts the use of endophytic actino bacteria having plant beneficial characteristics to reduce and replace the use of chemical inputs in the tea industry.



  • NASA reveals hole on Mars that could hold clue to life on Red Planet
    NASA released a photo of the mysterious hole on Mars that could hold a clue to life on Mars. The unusual hole on the planet was discovered in 2011.

    The image was taken by the High-Resolution Imaging Experiment (HiRISE) instrument. The photo was taken by Mars Reconnaissance Orbiter which currently circles the planet.

    Martian Pit:
    The image depicted the slopes of Mars' Pavonis Mons volcano.

    It is expected that the Martian pit might contain life as they have interior caves that remain relatively protected from the planet's harsh surface.

    As per the image, the hole has opened about 35 m across to an underground cavern which is estimated to be around 20 m deep.

    The crater is being studied to find out the reason for the circular crater surrounding this hole.
