    Touchdown! NASA’s Mars Perseverance Rover Safely Lands on Red Planet

    February 18, 2021, Categories  Astronomy/Space, Biology/Biotechnology, Environment/Geology

    Members of NASA’s Perseverance Mars rover team watch in mission control as the first images arrive moments after the spacecraft successfully touched down on Mars, Thursday, Feb. 18, 2021, at NASA’s Jet Propulsion Laboratory in Pasadena, California. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

    New hope for Treating Chronic Pain Without Opioids

    February 17, 2021, Categories  Physics, Biology/Biotechnology

    According to some estimates, chronic pain affects up to 40% of Americans, and treating it frustrates both clinicians and patients — a frustration that’s often compounded by a hesitation to prescribe opioids for pain.

    A new study from the University of Michigan School of Dentistry confirms that a low dose of a drug called naltrexone is a good option for patients with orofacial and chronic pain, without the risk of addiction, said first author Elizabeth Hatfield, a clinical lecturer in the Department of Oral and Maxillofacial Surgery and Hospital Dentistry.

    Naltrexone is a semisynthetic opioid first developed in 1963 as an oral alternative to naloxone, the nasal spray used to reverse opioid drug overdoses. When prescribed at doses of 50 to 100 milligrams, naltrexone
    blocks the effe...

    Mediterranean-style Diet linked to better Thinking Skills in later life

    February 14, 2021, Categories  Health/Medical, Biology/Biotechnology

    People who eat a Mediterranean-style diet — particularly one rich in green leafy vegetables and low in red meat — are more likely to stay mentally sharp in later life, a study shows.

    Closely adhering to a Mediterranean diet was associated with higher scores on a range of memory and thinking tests among adults in their late 70s, the research found.

    The study found no link, however, between the Mediterranean-style diet and better brain health. Markers of healthy brain ageing — such as greater grey or white matter volume, or fewer white matter lesions — did not differ between those regularly eating a Mediterranean diet and those who did not.

    These latest findings suggest that this primarily plant-based diet may have benefits for cognitive functioning as we get older, researchers...

    HOUSTON, TX – JUNE 30: (EDITORIAL USE ONLY) Medical staff wearing full PPE wrap a deceased patient with bed sheets and a body bag in the Covid-19 intensive care unit at the United Memorial Medical Center on June 30, 2020 in Houston, Texas. Covid-19 cases and hospitalizations have spiked since Texas reopened, pushing intensive-care wards to full capacity and sparking concerns about a surge in fatalities as the virus spreads.

    Algorithm using echocardiogram videos of the heart outperforms other predictors of mortality. Researchers at Geisinger have found that a computer algorithm developed using echocardiogram videos of the heart can predict mortality within a year.

    The algorithm – an example of what is known as machine learning, or artificial...
