  • Study suggests R rate for tracking pandemic should be dropped in favour of 'nowcasts'
    on September 28, 2021 at 11:00 pm

    When the COVID-19 pandemic emerged in 2020, the R rate became well-known shorthand for the reproduction of the disease. Yet a new study suggests it's time for 'A Farewell to R' in favor of a different approach based on the growth rate of infection rather than contagiousness.

    on September 28, 2021 at 8:04 pm

    Persistent gaps in life expectancy between Black and white Americans have been highlighted by the COVID-19 pandemic. Yet, this gap has narrowed by nearly 50% in three decades, largely due to improvements among Black Americans, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).

  • Addressing systemic inequities linked to readmission disparities for minority stroke patients
    on September 28, 2021 at 8:00 pm

    Racial minorities are disproportionately affected by stroke, with Black patients experiencing worse post-stroke outcomes than white patients. Racial disparities in stroke outcomes have been linked to suboptimal control of risk factors such as hypertension, lack of access to health care, and decreased utilization of neurologic services. However, it was previously unknown if outcomes for Black ischemic stroke patients were affected by care settings with insufficient nursing resources.

    on September 28, 2021 at 6:59 pm

  • Reducing salt in bread without sacrificing taste
    on September 28, 2021 at 6:56 pm

    Most people in the U.S. consume too much salt; adult Americans typically eat twice the daily amount recommended by dietary guidelines. Bread may not seem like an obvious culprit; however, due to high consumption and relatively high salt content, baked goods are a major source of sodium in the diet. A new study from the University of Illinois explores ways to reduce sodium in bread without sacrificing taste and leavening ability.

  • New technology leads successful clinical trial to treat dry eye disease
    on September 28, 2021 at 6:50 pm

    Several studies conducted over the last decade have concluded that dry eye disease (DED) affects up to 50% of the U.S. population, creating a liability for the nation's health care system that is estimated to exceed $50 billion annually. And though females and patients living with autoimmune disorders show a propensity for developing DED, the condition appears in all ethnicities and population demographics as people age.

  • Magnetic stimulation of the brain can improve episodic memory
    on September 28, 2021 at 6:00 pm

    Memories of past events and experiences are what define us as who we are, and yet the ability to form these episodic memories declines with age, certain dementias, and brain injury. However, a study publishing in the open access journal PLOS Biology on September 28th by Mircea van der Plas and Simon Hanslmayr from the University of Glasgow and colleagues, shows that low frequency repetitive transcranial magnetic stimulation—or rTMS—delivered over the left prefrontal cortex of the brain can improve memory performance by reducing the power of low frequency brain waves as memories form.

  • Study links air pollution to nearly 6 million preterm births around the world
    on September 28, 2021 at 6:00 pm

The accompanying Editorial publishing on September 28th is cowritten by the guest editors and Caitlin Moyer, and focuses specifically on the health of infants, children, and adolescents in the context of the UN Sustainable Development Goals (SDGs).

  • Living retina achieves sensitivity and efficiency engineers can only dream about
    on September 28, 2021 at 5:14 pm

    If you wanted to design the most perfect, low-energy, light-detecting device for a future camera or a prosthetic retina, you'd reach for something called 'efficient coding theory,' to set out the array of sensors.

  • How gene therapy can restore vision after stroke
    on September 28, 2021 at 5:13 pm

    Most strokes happen when an artery in the brain becomes blocked. Blood flow to the neural tissue stops, and those tissues typically die. Because of the locations of the major arteries in the brain, many strokes affect motor function. Some affect vision, however, causing patients to lose their vision or find it compromised or diminished. A research team led by Purdue University's Alexander Chubykin, an associate professor of biological sciences in the College of Science, in collaboration with the team led by Gong Chen at Jinan University, China, has discovered a way to use gene therapy to turn […]

  • More effective treatment of Alzheimer's
    on September 28, 2021 at 4:53 pm

    Developing effective treatment methods for Alzheimer's disease has proved difficult. The most effective, which have just been approved, only provide marginal effects. There are several major reasons why they are not effective, one of which is that the antibodies used do not bind to all the types of toxic clumps that cause Alzheimer's disease.

  • New mouse model for studying the cognitive protection mechanisms in Alzheimer's
    on September 28, 2021 at 4:36 pm

    Alzheimer's is a neurodegenerative disease that features the accumulation of the beta-amyloid peptide and Tau protein in the brain, which are associated with deficits in the neuronal connections and with dementia. However, researchers have recently discovered a type of people that despite the accumulation of these molecules, they do not develop dementia: the NDAN patients (non-Demented with Alzheimer's disease Neuropathology).

  • Low-carb diet shown to improve cardiometabolic risk profile
    on September 28, 2021 at 4:36 pm

    Low-carbohydrate diets are popular for weight loss and diabetes control. However, for most of the past 50 years, medical and public health experts have instead embraced low-fat diets, concerned about the health effects of saturated fats on cardiovascular risk factors like LDL cholesterol. As a result, low-fat and fat-free foods have proliferated—many of them high in processed carbohydrates.
