Blood Protein Helps Assess Cardiovascular Risks
Three new studies provide the strongest evidence to date that
a simple blood test for a molecule called C-reactive protein
(CRP) could help clinicians better identify and treat people
who are at risk for cardiovascular disease.

Ginkgo
Study Fails To Find Benefit in Preventing Dementia
The dietary supplement Ginkgo biloba was found to be
ineffective in reducing the development of dementia and Alzheimer's
disease in older people, according to a new study.

Imaging Compound May Help Predict Alzheimer’s Disease
A new brain imaging study has found that elderly people can develop
a key hallmark of Alzheimer’s disease in the brain without any
evidence of cognitive impairment. The researchers hope that their
detection method will one day help predict who will develop Alzheimer’s
disease in 5 to 10 years.

Earlier
Jaundice Treatment Decreases Brain Injury in Preemies
A new study has found that early treatment to prevent severe
jaundice in extremely early preterm infants can reduce the rate
of brain injury, a serious complication of jaundice.

Longer
Treatment Improves Outcomes for Opioid-Addicted Youth
Young adults addicted to opioids were more successful at remaining
drug-free when they received longer treatment with a medication
than those who received the same treatment for only 2 weeks.

Children
with Egg Allergies May Tolerate Heated Egg
A new study has found that the majority of children with egg
allergy may be able to eat some baked foods containing egg. The
early results also raise the possibility that the gradual introduction
of extensively heated egg may help alleviate some children’s
allergy to regular egg.

Warm
Hands, Warm Feelings
We often use terms like "warm" and "cold" to
describe people. New research shows this may not just be a linguistic
oddity; sensations and psychological concepts are actually linked
in our minds.

Where
Fat Comes From
Researchers have found that most fat cells arise from cells in
the walls of blood vessels in fat tissue. This insight may lead
to new approaches to prevent and treat obesity.

Insight
into Post-Exercise Fatigue in Muscular Dystrophy
In a finding that may lead to a better understanding of the post-activity
exhaustion that strikes many people with muscular dystrophy,
scientists have identified a disrupted molecular pathway that
leads to fatigue in mice with muscular dystrophy after even mild
physical exertion. This fatigue can be relieved by giving the
animals a drug that bypasses the disruption.

Large-Scale
Genetic Study Sheds Light on Lung Cancer
In the largest effort of its kind, scientists have charted the
genetic changes involved in the most common form of lung cancer,
implicating more than a dozen new genes.

Artificial
Connections Restore Movement to Paralyzed Limbs
For the first time, researchers have shown that a direct artificial
connection from the brain to muscles can restore movement in
monkeys whose arms have been temporarily anesthetized.

Novel
Type of Antibody Inhibits HIV Infection
Scientists have identified a small antibody fragment that is
highly effective at neutralizing the human immunodeficiency virus
(HIV). The finding may lead to new treatments against HIV and
other viruses.

Scientists
Analyze Genome of Relapsing Malaria Parasite
Scientists have deciphered the complete genetic sequence of the
parasite Plasmodium vivax, the leading cause of relapsing
malaria. The distinctive genetic features of P. vivax may
lead to new tools for preventing and treating relapsing malaria.

Office-Based
Treatment Best for Childhood Vision Disorder
Children with convergence insufficiency, a common eye-muscle
disorder, responded better to treatments that included weekly
office visits to a trained therapist than to strictly home-based
regimens, which are more often prescribed.

Insights
into Immune Cell Matchmaker Protein
Scientists have identified a protein that plays matchmaker between
2 key types of immune cells, T and B cells, enabling them to
establish long-lasting immunity after an infection.

New
Genes Linked to Gout
Researchers have identified 2 new genes—and confirmed the role
of a third—that are associated with increased risk of higher
levels of uric acid in the blood, which can lead to gout, a common,
painful form of arthritis.

Rethinking
Metastasis
Most cancer deaths result from metastasis, the spread of cancer
from a tumor to other parts of the body. Researchers have long
thought that metastasis comes at a late stage of cancer. A new
study suggests the process may start long before that.

Making "Safer" Stem
Cells
Scientists have developed a new technique to convert adult liver
and other cells into versatile stem cells. By using a common
cold virus, it sidesteps the cancer-causing potential of a previously
developed method using a different kind of virus.
