Probes shed new light on Alzheimer’s cause

Rice University researchers have found a way to track the formation of soluble amyloid beta peptide aggregates implicated in the onset of Alzheimer’s disease. The Rice lab of Angel Martí reported its development of a ruthenium-based fluorescent complex that binds to soluble, oligomeric amyloid beta peptides. As the peptides come together to form the […]

Light-activated metal catalyst destroys cancer cells' vital energy source

A space-age metal that formed part of the asteroid that destroyed the dinosaurs could provide a new method of treating cancer tumours selectively using light. Scientists at the University of Warwick in collaboration with colleagues in China, France, Switzerland and Heriot-Watt University have developed a technique that uses light to […]

Bathroom Scale Could Monitor Millions with Heart Failure

“Good morning. Bill. Please. Step onto the scale. Touch the metal pads.” The device records an electrocardiogram from Bill’s fingers and – more importantly – circulation pulsing that makes his body subtly bob up and down on the scale. Machine learning tools compute that Bill’s heart failure symptoms have worsened. […]

Basic Cell Discovery Could Lead to Improved Drugs for Heart Failure

Michigan Medicine researchers determine that receptors inside heart cells could be targets for better beta blockers. Beta blockers are versatile drugs that have been around since the 1960s that can help slow heart rate and lower blood pressure – a fact that isn’t lost on certain musical soloists who take them […]

Capturing cancer cells in 3-D

What makes cancer so deadly is its ability to spread, a process called metastasis. This doesn’t take place on a flat surface like a petri dish; it happens in the 3-D world of the human body. Stopping or even slowing it holds promise for extending the lives of cancer patients. […]

A Child’s Shattered Chromosomes Illustrate the Value of Supportive Therapies

To a trained eye, the chromosome chart (karyotype) above has 4 irregularities, circled in red. They’re chromosome pairs of uneven size. The chromosomes represent genetic material missing or extra, but also a beautiful girl. Her father contacted me after he read my recent post about a friend’s child with a rare mutation […]

Heart Function: Built to Endure

Major physical changes occurred in the human heart as people shifted from hunting and foraging to farming and modern life. As a result, human hearts are now less “apelike” and better suited to endurance types of activity. But that also means those who lead sedentary lives are at greater risk for […]

Brain tumors form synapses with healthy neurons, Stanford-led study finds

Scientists at the Stanford University School of Medicine have shown for the first time that severe brain cancers integrate into the brain’s wiring. The tumors, called high-grade gliomas, form synapses that hijack electrical signals from healthy nerve cells to drive their own growth. Experiments demonstrated that interrupting these signals with an existing […]

Study gives the green light to the fruit fly’s color preference

For more than a century, the humble and ubiquitous fruit fly has helped scientists shed light on human genetics, disease, and behavior. Now a new study by University of Miami researchers reveals that the tiny, winged insects have an innate time- and color-dependent preference for light, raising the intriguing possibility […]

Cancer cells turn to cannibalism to survive chemotherapy

Researchers from Tulane University School of Medicine have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells. The study, which was published in the Journal of Cell Biology, suggests that this act of cannibalism provides these cancer cells with the energy they need to stay alive and initiate tumor […]

Early maternal anemia tied to intellectual disability, ADHD and autism

The timing of anemia—a common condition in late pregnancy—can make a big difference for the developing fetus, according to research at Karolinska Institutet published in JAMA Psychiatry. The researchers found a link between early anemia and increased risk of autism, ADHD and intellectual disability in the child. Anemia discovered toward […]

Multi-institutional team to study effects of age, gender on brain injury mechanics

Traumatic brain injury and chronic traumatic encephalopathy (CTE) have become common in athletes who suffer repeated blows to the head. Most recently, former New England Patriots tight end Rob Gronkowski revealed that he had sustained about 20 concussions during his nine-year career in the National Football League. Now, a team […]

Regulatory heft needed to curb false promises on stem cells, says health law expert

The legal and regulatory tools designed to protect the public from the marketing of unproven stem cell therapies will remain ineffective without bureaucratic will and grassroots efforts, according to a University of Alberta health law expert. “There's this perception that stem cells are revolutionizing science and they have transformed medicine […]

Study points to new drug target in fight against cancer

Researchers have identified a potential new drug target in the fight against cancer. In a study in the Proceedings of the National Academy of Sciences, an international team of researchers describe how a cancer-linked version of the protein mitoNEET can close the primary gateways in the outer surface of mitochondria, the “power plants” […]

Testing chemicals for birth defects using stem cells, not mice

Researchers at the University of California, Riverside, are part of an ambitious plan at the U.S. Environmental Protection Agency, or EPA, to eliminate animal testing by 2035. Their contribution: developing a way to test whether chemicals cause musculoskeletal birth defects using lab-grown human tissue, not live animals. Nicole zur Nieden, an […]

Once-common hysterectomy technique linked to worse uterine cancer outcomes

Every year, nearly 700,000 American women have surgery to remove their uterus (hysterectomy) or uterine fibroids (myomectomy). A laparoscopic surgical technique once commonly used in these procedures could be worsening the outcomes for women who have undiagnosed uterine cancer at the time of the procedure, reports a Yale-led study in the […]

A curiosity driven genetic discovery that should impact cancer treatments

A team of geneticists with a desire to understand the inner workings of genes implicated in cellular identity has discovered new biological targets that may help devise alternative therapies for cancers that are becoming resistant to existing drugs. First discovered in fruit flies, Polycomb genes were initially studied due to their essential […]

Researchers build microscopic biohybrid robots propelled by muscles, nerves

Researchers have developed soft robotic devices driven by neuromuscular tissue that triggers when stimulated by light – bringing mechanical engineering one step closer to developing autonomous biobots. In 2014, research teams led by mechanical science and engineering professor Taher Saif and bioengineering professor Rashid Bashir at the University of Illinois worked together to developed the first self-propelled biohybrid swimming and walking biobots […]

Fruit flies’ microbiomes shape their evolution

The expression “you are what you eat” has taken on new meaning. In an experiment in fruit flies, or Drosophila melanogaster, researchers at the University of Pennsylvania have found that adding different species of microbes to the flies’ food caused populations to diverge genetically, racking up significant genomic changes in just five […]

Study gives clues to the origin of Huntington’s disease, and a new way to find drugs

The first signs of Huntington’s, an inherited disease that slowly deteriorates bodies and minds, don’t typically surface until middle age. But new findings suggest that something in the brain might be amiss long before symptoms arise, and earlier than has ever been observed. Using a new technology, Rockefeller scientists were […]

Prostate Cancer Patients Can Pursue Healthy Sex Lives After Surgery

There’s a perception that surgery to treat prostate cancer will spell the end of a man’s sex life. And while that often used to be the case, survivorship programs, like the one at the University of Michigan Rogel Cancer Center, offer counseling and interventions to promote sexual recovery after cancer treatment.

“Fat Shaming” Won’t Solve Obesity. Science Might.

Science is with James Corden. Fat shaming shouldn’t make a comeback, and it won’t solve the nation’s obesity epidemic. Through countless published scientific papers, research has continually exposed the complexity of obesity and being overweight, which affects more than 1.9 billion people worldwide. That research has led experts to conclude that potential treatment options […]
