Researchers unravel separate biological responses of the eye to blue light

Researchers unravel separate biological responses of the eye to blue light

Blue light can both set the mood and set in motion important biological responses. Researchers at the University of Pennsylvania's School of Medicine and School of Arts and Sciences have teased apart the separate biological responses of the human eye to blue light, revealing an unexpected contest for control.

Lactobacillus-containing probiotics can improve lupus symptoms

Lactobacillus-containing probiotics can improve lupus symptoms

Lactobacillus species, commonly seen in yogurt cultures, correlate, in the guts of mouse models, with mitigation of lupus symptoms, while Lachnospiraceae, a type of Clostridia, correlate with worsening, according to research published ahead of print in Applied and Environmental Microbiology. [More]
New study reveals how cancer becomes drug resistant over time

New study reveals how cancer becomes drug resistant over time

Like a colony of bacteria or species of animals, cancer cells within a tumor must evolve to survive. A dose of chemotherapy may kill hundreds of thousands of cancer cells, for example, but a single cell with a unique mutation can survive and quickly generate a new batch of drug-resistant cells, making cancer hard to combat.

Study: People appreciate fairness in the same way as they appreciate money for themselves

Ever wondered how people figure out what is fair? Look to the brain for the answer. According to a new Norwegian brain study, people appreciate fairness in much the same way as they appreciate money for themselves, and also that fairness is not necessarily that everybody gets the same income.

Right kind of mental rest helps boost future learning.

Right kind of mental rest helps boost future learning.

A new study, which may have implications for approaches to education, finds that brain mechanisms engaged when people allow their minds to rest and reflect on things they've learned before may boost later learning. [More]

Researchers uncover surprising way to reduce brain damage caused by head injuries

Researchers uncover surprising way to reduce brain damage caused by head injuries

Scientists have uncovered a surprising way to reduce the brain damage caused by head injuries - stopping the body's immune system from killing brain cells. The study, published in the open access journal Acta Neuropathologica Communications, showed that in experiments on mice, an immune-based treatment reduced the size of brain lesions. [More]
Newborns of mothers who smoke during pregnancy have altered stress hormones, DNA

Newborns of mothers who smoke during pregnancy have altered stress hormones, DNA

Researchers from The Miriam Hospital have studied the effects of smoking during pregnancy and its impact on the stress response in newborn babies. Their research indicates that newborns of mothers who smoke cigarettes during pregnancy show lower levels of stress hormones, lowered stress response, and alterations in DNA for a gene that regulates passage of stress hormones from mother to fetus.

Study on blind cave fish could reveal mechanisms behind eye disease, other human ailments

Study on blind cave fish could reveal mechanisms behind eye disease, other human ailments

Blind cave fish may not be the first thing that comes to mind when it comes to understanding human sight, but recent research indicates they may have quite a bit to teach us about the causes of many human ailments, including those that result in loss of sight. [More]
Whole exome sequencing can assist in early diagnosis of various disorders

Whole exome sequencing can assist in early diagnosis of various disorders

Approximately one-fourth of the 3,386 patients whose DNA was submitted for clinical whole exome testing received a diagnosis related to a known genetic disease, often ending a long search for answers for them and their parents, said researchers from the Baylor College of Medicine departments of molecular and human genetics and pediatrics and the Baylor Human Genome Sequencing Center and the University of Texas Health Science Center at Houston.

Low vitamin D levels linked to poor brain function after sudden cardiac arrest

Low vitamin D levels linked to poor brain function after sudden cardiac arrest

Vitamin D deficiency increases the risk of poor brain function after sudden cardiac arrest by seven-fold, according to research presented at Acute Cardiovascular Care 2014 by Dr Jin Wi from Korea. Vitamin D deficiency also led to a higher chance of dying after sudden cardiac arrest. [More]
MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.
