Study IDS Risk Factors for Irregular Heartbeats in Hypertrophic Cardiomyopathy Patients

New research will help doctors identify, treat and prevent potentially dangerous irregular heartbeats in patients with hypertrophic cardiomyopathy, a common heart condition in which the heart thickens and strains to pump blood. These chaotic heart rhythms are known as atrial fibrillation. Atrial fibrillation can be asymptomatic, but it can lead […]

Study Finds COVID-19 Reinfection Rate Less Than 1% for Those with Severe Illness

A review of more than 9,000 U.S. patients with severe COVID-19 infection showed less than 1% contracted the illness again, with an average reinfection time of 3.5 months after an initial positive test. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU […]

Rats prefer to help their own kind. Humans may be similarly wired

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new UC Berkeley research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share […]

Your Immune System Could Turn COVID-19 Deadly

Hidden autoimmunity may explain how the coronavirus wreaks such widespread and unpredictable harm. One of the enduring mysteries of COVID-19 is why it makes some people deathly sick but gives others only mild symptoms or none at all. We know that age matters, as do race; gender; and pre-existing medical […]

Gene Therapy Offers Long-Awaited Hope for Children with Rare, Incurable Disorder

Children with a devastating genetic disorder characterized by severe motor disability and developmental delay have experienced sometimes dramatic improvements in a gene therapy trial launched at UC San Francisco Benioff Children’s Hospitals. The trial includes seven children aged 4 to 9 born with a deficiency of AADC, an enzyme involved […]

Identifying the spark of desire in fruit flies

Fruit flies have evolved an elaborate courtship ritual. Upon recognizing a suitable mate in his vicinity, a male fruit fly transforms into a dogged suitor, sometimes chasing the female for more than 26 yards, or 9 miles in human terms, singing to her all the while by vibrating his wings. […]

Anti-androgen therapy may fuel spread of bone tumours in advanced prostate cancer

Anti-androgen therapy is commonly used to treat patients with advanced prostate cancer at stages where the disease has spread to the bones. However, new research reveals that anti-androgen treatment can actually facilitate prostate cancer cells to adapt and grow in the bone tumour microenvironment model, which has been developed by […]

Anti-coagulant drug could treat COVID-19’s emerging variants

Molecules from the same family as the anti-coagulant drug heparin may interfere with the ability of the COVID-19 virus’s spikes to bind to human cells. This could be used to treat people with severe effects of the virus and any emerging variants. New targetable site on the COVID-19 spike protein […]

Scientists blueprint bacterial enzyme believed to play “stealthy” role in suppressing immune response

Scientists have produced the first fine-detail molecular blueprints of a bacterial enzyme known as Lit, which is suspected to play a “stealthy” role in the progression of infection by reducing the immune response. Blueprints such as these allow drug designers to uncover potential weaknesses in bacterial arsenals as they seek to develop […]

Sex differentiation in transsexual kelp

Researchers from the Max Planck Institute for Developmental Biology in Tübingen and their collaborators describe a strain of giant kelp that is genetically male, but presents phenotypic features of females. Their findings shed light on the molecular basis of how sexual development is initiated in this species. Giant kelp can […]

Normal brain growth curves for children developed

In the United States, nearly every pediatric doctor’s visit begins with three measurements: weight, height and head circumference. Compared to average growth charts of children across the country, established in the 1970s, a child’s numbers can confirm typical development or provide a diagnostic baseline to assess deviations from the curve. Yet, […]

Brain research uncovers “perfect storm” linked to neurodegenerative disease

A 'perfect storm' of genetic mutations, toxic proteins and a defect in natural cell recycling has been uncovered in University of Queensland research that could lead to treatments for neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Researchers have found brain cells are particularly vulnerable to the impacts of the triple threat, […]

An 'astounding' find reveals a rare cause of epilepsy

Researchers at The University of Queensland, working to gain a better understanding of how brain cells work, have discovered the underlying mechanism of a rare genetic mutation that can cause epilepsy. Dr Victor Anggono from UQ’s Queensland Brain Institute said his team made the ground-breaking findings while researching nerve cell communications, which are […]

A fermented-food diet increases microbiome diversity and lowers inflammation

A diet rich in fermented foods enhances the diversity of gut microbes and decreases molecular signs of inflammation, according to researchers at the Stanford School of Medicine. In a clinical trial, 36 healthy adults were randomly assigned to a 10-week diet that included either fermented or high-fibre foods. The two diets […]

Can blood be used to predict age-related diseases?

How much can a simple blood sample tell us about a person’s health? Can it give clues about whether a person will develop cardiovascular disease or leukemia? Can it predict how severe a person’s heart disease will be? John Dick, senior scientist at Princess Margaret Cancer Centre, University Health Network […]

A New Diagnostic Tool for Small Tumors in Breasts

A bioengineering professor at The University of Texas at Arlington is developing a technique to diagnose tiny breast tumors that could reduce the anxiety, uncertainty and high costs often faced by patients. Biopsy results show that about 80% of very small tumors are benign; 15% are low-grade, non-life-threatening cancers; and […]

The Side Effects of Vaccines – How High is the Risk?

Vaccines, like many other things in the world, sometimes have a negative side attached to their main positive effect of protecting us against different – and potentially lethal – diseases. Luckily, this 'negative side' has a very, very low chance of manifesting in practice. Many different tests and clinical trials […]
