A new study reported in Nature Communications has discovered activators for molecules that act as motors to move materials around within nerve cells.
Nerve cells form the basis of the nervous system in animals, as they transfer information between the various sensory and effector organs of the body and the brain and spinal cord. However, this function relies heavily on the transport of several proteins and other molecules between various parts of the cell. (Photo by Robina Weermeijer on Unsplash)
A nerve cell comprises a cell body, and multiple short branches called dendrites. It also has a long projection called the axon which carries signals away from the neuron. Nerve cells also have tiny tubular tracks composed of microtubules along which cargo is moved to and from the dendrites and axons by an attached molecular motor called KIF1C...

An injection of nanoparticles can prevent the body's immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis.
NN ARBOR--The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells—call it an "EpiPen" for trauma to the central nervous system, which includes the brain and spinal cord.

"In this work, we demonstrate that instead of overcoming an immune response, we can co-opt the immune response to work for us to promote the therapeutic response," said Lonnie Shea, the Steven A. Goldstein Collegiate Professor of Biomedical Engineering.
Trauma of any kind kicks the body's immune response into gear...

Do you remember the old expression that says the way to a man's heart is through his stomach?
Well it turns out that's right. But not in the way you think!
But you won't hear that from mainstream doctors.
They're still stuck in the 20th century belief that high cholesterol is the root cause of heart disease and a low-fat diet is the cure. And for the past 60 years, we've spent billions on cholesterol-lowering statin drugs and fat-free foods...

Novel material from Israel may prevent one of the costliest and most prevalent bacterial diseases in the world.
Novel dental fillings made of resin-based composites enhanced by antibacterial nano-assemblies, developed at Tel Aviv University, can hinder bacterial growth on dental restorations, the main cause of recurrent cavities that can lead to root-canal treatment and tooth extractions.

"Antibiotic resistance is now one of the most pressing healthcare problems facing society, and the development of novel antimicrobial therapeutics and biomedical materials represents an urgent unmet need," said lead researcher Dr. Lihi Adler-Abramovich.
"When bacteria accumulate on the tooth surface, they ultimately dissolve the hard tissues of the teeth...

While we know that chronic inflammation in the body hurts the brain, did you know the reverse is true as well? Stress and anxiety cause inflammation.
The anxiety-inflammation-brain cycle can be especially detrimental to those who cannot break out of a stressful lifestyle.
Anxiety Is a Widespread Issue
While everyone deals with different emotions, including stress, worry, and sadness, chronic anxiety is different. It's considered a mental disorder, and it's the most common ones in the United States, affecting more than 40 million adults (1)...

Phthalates are hormone-disrupting plastics chemicals linked to a number of adverse health effects, such as disturbing infant and child development, and, in adults, may affect reproductive health in men and endometriosis in women, and is associated with increased abdominal fat in both. "Given the increasing scientific evidence base linking phthalate exposure with harmful health outcomes, it is important to understand major sources of exposure," which I discuss in my video What Diet Best Lowers Phthalate Exposure?
What is the most major exposure source? Diet. If you have people stop eating for a few days, you get a significant drop in the amount of phthalates spilling out in their urine. One can only fast for so long, though. Thankfully, we can see similar drops just from eating a plant-based diet for a few days, which gives us a clue as to where most phthalates are found...

Breakthrough study fills a 'missing gap,' Baylor University researcher says.
A team led by a Baylor University researcher has published a breakthrough article that provides a better understanding of the dynamic process by which sunlight-induced DNA damage is recognized by the molecular repair machinery in cells as needing repair. (Photo by chuttersnap on Unsplash)
Ultraviolet light from the sun is a ubiquitous carcinogen that can inflict structural damage to the cellular DNA. As DNA carries important blueprints for cellular functions, failure in removing and restoring damaged parts of DNA in a timely fashion can have detrimental outcomes and lead to skin cancers in humans, said lead author Jung-Hyun Min, Ph.D., associate professor of chemistry and biochemistry in Baylor's College of Arts & Sciences...

When we think about life's biggest decisions, images of choosing the right spouse, career or home come to mind. What to eat? Not so much.
New research may change that. Scientists now know our body has five natural defense systems that are magnificently effective at warding off our scariest diseases. There is a catch, however. These defense systems only work properly when nourished with healthy foods. (Photo by MindBodyStock on Unsplash)
In his new book Eat to Beat Disease Dr. William Li explains how our body's defense systems work and lists 200 foods that keep them humming...

Glyphosate, a synthetic herbicide patented in 1974 by the Monsanto Company and now manufactured and sold by many companies in hundreds of products, has been associated with cancer and other health concerns. Glyphosate is best known as the active ingredient in Roundup-branded herbicides, and the herbicide used with "Roundup Ready" genetically modified organisms (GMOs).
Herbicide tolerance is the most prevalent GMO trait engineered into food crops, with some 90% of corn and 94% of soybeans in the U.S. engineered to tolerate herbicides, according to USDA data. A 2017 study found that Americans' exposure to glyphosate increased approximately 500 percent since Roundup Ready GMO crops were introduced in the U.S in 1996. Here are some key facts about glyphosate: (Photo by meriç tuna on (Continue reading...)
