Virus that causes COVID-19 can find alternate route to infect cells

Early in the COVID-19 pandemic, scientists identified how SARS-CoV-2, the virus that causes COVID-19, gets inside cells to cause infection. All current COVID-19 vaccines and antibody-based therapeutics were designed to disrupt this route into cells, which requires a receptor called ACE2. Now, researchers at Washington University School of Medicine in […]

Bourneville's tuberous sclerosis: everything unfolds in the brain shortly after birth

A Canadian research team has uncovered a new mechanism involved in Bourneville tuberous sclerosis (BTS), a genetic disease of childhood. The team hypothesizes that a mutation in the TSC1 gene causes neurodevelopmental disorders that develop in conjunction with the disease. Seen in one in 6,000 children, tuberous sclerosis causes benign […]

Caloric Restriction Alters Microbiome, Enhancing Weight Loss but Increasing Pathogenic Bacteria

Researchers at UC San Francisco have found that extreme caloric restriction diets alter the microbiome in ways that could help with weight loss but might also result in an increased population of Clostridioides difficile, a pathogenic bacterium that can lead to severe diarrhoea and colitis. Such diets, which allow people only […]

Mysteries of the heart: researchers find small mutation disrupts protein network, causing heart disease

Each day the average human heart beats 100,000 times and pumps about 2,000 gallons of blood. It’s a process that is critical to life, and yet it often goes awry for unknown reasons.   “Despite knowing a lot about muscle contraction and the heart, in particular, there are still a number of questions scientists have […]

Scientists designed a promising non-invasive treatment for Alzheimer’s disease

Blood-brain barrier typically protects the brain, but is also quite a bit of a challenge for scientists trying to create therapies for neurological conditions. Drugs that should act on the brain struggle to pass this barrier. Now scientists at The University of Queensland have found that an ultrasound therapy could […]

Latest data on immune response to COVID-19 reinforces need for vaccination

New research has found that previous infection, whether it was symptomatic or asymptomatic, does not necessarily protect you long-term from COVID-19, particularly against new Variants of Concern. The preprint study was led by the University of Oxford, in collaboration with the Universities of Liverpool, Sheffield, Newcastle and Birmingham with support […]

Investigational Alzheimer’s drug improves biomarkers of the disease

An investigational Alzheimer’s drug reduced molecular markers of disease and curbed neurodegeneration in the brain, without demonstrating evidence of cognitive benefit, in a phase 2/3 clinical trial led by researchers at Washington University School of Medicine in St. Louis through its Dominantly Inherited Alzheimer Network-Trials Unit (DIAN-TU). These results led the trial […]

Protein linked to heart health, disease a potential therapeutic target for dementia

By the time people with Alzheimer’s disease start exhibiting difficulty remembering and thinking, the disease has been developing in their brains for two decades or more, and their brain tissue already has sustained damage. As the disease progresses, the damage accumulates, and their symptoms worsen. Researchers at Washington University School […]

Congenital heart deficit makes patient twice a trailblazer

Her first intervention was at the dawn of open-heart surgery. This month she got a newly available pulmonary valve, placed with a tiny incision. In 1958, Susie Knudsen became a 12-year-old trailblazer as one of the first children anywhere to undergo open-heart surgery.  After she suffered a heart attack in […]

Bedtime and electronics are a poor combo for teens, study finds

Middle schoolers who spend time on smartphones, laptops and tablets in the hour before bed are likely to sleep poorly and be more tired the next day, leading them to use media devices at bedtime even more. Those are among the findings of a study published by the National Sleep Foundation by […]

Study examines how breast implant surfaces affect immune response

Rice University bioengineers collaborated on a six-year study that systematically analyzed how the surface architecture of breast implants influences the development of adverse effects, including an unusual type of lymphoma. Every year, about 400,000 people receive silicone breast implants in the United States. According to FDA data, most of those […]

Targeted tumors attack not-innocent bystanders

How do you kill tumor cells that can’t be targeted? Get their more susceptible neighbors to help. The Rice University lab of synthetic chemist K.C. Nicolaou, in collaboration with AbbVie Inc., has created unique antibody-drug conjugates (ADCs) that link a synthetic uncialamycin analogue to antibodies that target cancer cells. Once they enter the […]

Salton Sea aerosol exposure triggers unique and mysterious pulmonary response

Communities surrounding the Salton Sea, the inland body of water straddling California’s Riverside and Imperial counties, show high rates of asthma due, possibly, to high aerosol dust levels resulting from the sea shrinking over time. Scientists suspect, however, the Salton Sea plays an additional role in pulmonary health. A University […]
