New Light Shed On Enigma Of Salt Intake And Hypertension
- ScienceDaily
- 09/5/4 06:00
A high salt intake has been implicated in cardiovascular disease risk for 5000 years. But salt-sensitive hypertension still remains an enigma. Now, investigators have shed new light on the relationship between salt intake, bodily processes, and blood pressure regulation. Within the skin, they have detected a new storage area for salt in the body. If the process behind this storage is defect,...

Patients with chronic hepatitis C that has been resolved through therapy or immune response may still be able to infect others with the virus.
Psyched Out By Stereotypes: Research Suggests Thinking About The Positive
- ScienceDaily
- 09/5/4 06:00
Cognitive scientists have shown that when aware of both a negative and positive stereotype related to performance, women will identify more closely with the positive stereotype, avoiding the harmful impact the negative stereotype unwittingly can have on their performance. This is the first study to examine the influence of concurrent stereotypes, one negative and one positive. It also demonstrated...
Stopgap DNA Repair Needs A Second Step
- ScienceDaily
- 09/5/4 06:00
Genetic "mistakes" can occur following a certain form of error-prone DNA repair. Scientists have now revealed how this two-step process takes place. Understanding how this major form of DNA repair works can have significant clinical implications. Since defects in this process increase the risk of cancer, clarifying its nuts and bolts might one day make it possible to enhance it in people whose...

Researchers have revealed a unique strategy evolved by sea urchins to keep their digging teeth sharp enough to carve out hiding holes in limestone.
White Blood Cells Can Sprout 'Legs' And Move Like Millipedes
- ScienceDaily
- 09/5/4 06:00
Scientists have shown that rather than inching along blood vessel walls to reach injured tissue, white blood cells sprout hundreds of "legs" that grip the vessel walls and propel them, millipede-like, to the proper site.
Pacifiers No Barrier To Breastfeeding Success
- ScienceDaily
- 09/5/4 04:00
Many women have heard of the benefits of breastfeeding and pacifier use in reducing the risk of Sudden Infant Death Syndrome (SIDS) as well as other advantages. But many may question the effects of pacifiers on breastfeeding success. Mothers need not worry about that, according to a review of relevant...
Parkinson's: Neurons Destroyed By Three Simultaneous Strikes
- ScienceDaily
- 09/5/4 04:00
In a study that reveals the clearest picture to date of neuron death in Parkinson's disease, researchers have found that a trio of culprits acting in concert is responsible for killing the brain cells. The study showed that three molecules -- the neurotransmitter dopamine, a calcium channel, and a protein called alpha-synuclein -- act together to kill the neurons. A new theory of Parkinson's...
