Same mutation aided evolution in many fish species, Stanford study finds

After decades of laboratory work studying how animals evolve, researchers sometimes need to put on the hip waders, pull out the fishing net and go learn how their theory compares to the real world. According to a Stanford University School of Medicine study published in the March 25 issue of Science, Mother Nature is more predictable than lab experiments suggest. . In a diverse group of fish call...

First real-time view of developing neurons reveals surprises, say Stanford researchers

Scientists have believed that neurons need a long period of fine-tuning and training with other neurons before they take on their adult role. But after using new technology for the first time to watch these cells develop, a team of researchers at the Stanford University School of Medicine found that neurons come into this world with a good idea about what they'll become as adults. . The work, whi...

For one Stanford doctor, the beat goes on during open-heart surgery

In a Stanford Hospital surgery room on a recent afternoon, heart surgeon Kai Ihnken demonstrated how he repositions the beating heart while it's still inside the chest of a 78-year-old man undergoing triple bypass surgery. The surgeon reached into the chest, lifted the beating heart out, then craned his neck to the side, just so, searching for the right spot on the back of the heart to attach the...

Stanford study of owls finds link in brain between sight and sound

Just imagine listening to someone talk and also hearing the buzz of the overhead lights, the hum of your computer and the muffled conversation down the hallway. To focus on the person speaking to you, your brain clearly can't give equal weight to all incoming sensory information. It has to attend to what is important and ignore the rest. . Two scientists at the Stanford University School of Medic...

Stanford/Packard scientist's data-mining technique strikes genetic gold

A new method to mine existing scientific data may provide a wealth of information about the interactions among genes, the environment and biological processes, say researchers at the Stanford University School of Medicine, Lucile Packard Children's Hospital and Harvard Medical School.

Chocolate, wine, spicy foods may be OK for heartburn, Stanford study finds

Patients have been known to hug Lauren Gerson, MD, so overjoyed are they at hearing her words. What does she say to them? Go ahead and eat chocolate. Indulge your passion for spicy cuisine. Drink red wine. Enjoy coffee when you want it, have that orange juice with breakfast and, what the heck, eat a grapefruit, too. Gerson says that for most heartburn patients, there's insufficient evidence to su...

Stanford snake venom study shows that certain cells may eliminate poison

Death by snakebite is horrible. The immediate pain of the bite is followed by swelling, bruising and weakness, then sweating or chills, with numbness, nausea, blurred vision and possibly convulsions before it's all over. Such misery is produced by a veritable witches' brew of toxins in snake venom. . It's long been thought that the body's own immune system, rather than reducing the symptoms, may...

For Stanford scientists, RNAi gene therapy takes two steps forward, one step back

Three years ago Mark Kay, MD, PhD, published the first results showing that a hot new biological phenomenon called RNA interference was an effective gene-therapy technique in mice.

Now, with three human RNAi gene therapy trials under way, Kay's initial excitement is proving to be on...

Salk and Stanford teams join forces to reveal two paths of neurodegeneration

Wiring the developing brain is like creating a topiary garden. Shrubs don't automatically assume the shape of ornamental elephants, and neither do immature nerve cells immediately recognize the "right" target cell. Abundant foliage, either vegetal or neuronal, must first sprout and then be sculpted into an ordered structure. . Neurons extend fibers called axons to target cells in an exuberant man...

Stanford discovery may help predict when toxoplasma can be deadly

Toxoplasma is arguably the most successful animal parasite on earth: It infects hundreds of species of warm-blooded animals, most notably half of humanity.
