Contact lenses recommended for babies after cataract surgery
Date: Mar-07-2014It is standard for adults and children who undergo cataract surgery to be implanted with an artificial lens in their eye. But a clinical trial funded by the National Eye Institute suggests that the ideal treatment for infants should be surgery followed by the use of contact lenses for several years, and then an eventual lens implant.A cataract is a cloud on the lens of the eye. Removal of cataracts involves a quick, safe surgical procedure, which is usually followed by the artificial lens - called an intraocular lens (IOL) - being implanted.
New drug could reverse age-related cognitive decline
Date: Mar-07-2014As we age, many of us may struggle to remember simple things, such as directions or what film we watched last night. But researchers from the University of Florida say they have discovered a drug that has the potential to reverse mild cognitive decline among older adults.This is according to a study recently published in the Journal of Neuroscience.The research team, including Prof. Jennifer Bizon of the university's Department of Neuroscience, explains that the type of memory responsible for the recall of day-to-day items is known as the "working memory.

Prenatal nicotine exposure may lead to ADHD in future generations
Date: Mar-07-2014Prenatal exposure to nicotine could manifest as attention deficit hyperactivity disorder in children born a generation later, according to a new study by Florida State University College of Medicine researchers.Professors Pradeep G. Bhide and Jinmin Zhu have found evidence that ADHD associated with nicotine can be passed across generations. In other words, your child's ADHD might be an environmentally induced health condition inherited from your grandmother, who may have smoked cigarettes during pregnancy a long time ago.
Young nonmelanoma skin cancer survivors more likely to get other cancers later
Date: Mar-07-2014People who had nonmelanoma skin cancer (NMSC) were at increased risk for subsequently developing melanoma and 29 other cancer types, and this association was much higher for those under 25 years of age, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.NMSC is the most common type of skin cancer. It is relatively easy to treat if detected early, and rarely spreads to other organs.
After a decade of debate, a clear picture of a controversial protein that helps regulate heart contractions
Date: Mar-07-2014Brandeis University researchers have unlocked a controversial structure in heart cells responsible for regulating heart contractions.For years, scientists have debated how many KCNE1 proteins are required to build a potassium ion channel, theorizing anywhere between one and 14. Now, Brandeis University researchers found that these channels are built with two E1s. Understanding the construction of this channel is key to understanding life-threatening heart conditions, such as arrhythmias, and developing drugs to threat those conditions.
Studying bat brains has implications for humans
Date: Mar-07-2014Could a new finding in bats help unlock a mystery about the human brain? Likely so, say researchers at Georgetown University Medical Center who have shown that a small region within the amygdala, an almond-shaped structure in the brains of all mammals, is responsible for producing emotional calls and sounds. They say this discovery might be key to locating a similar center in human brains.

Link discovered between sharp vision and the brain's processing speed
Date: Mar-07-2014Middle-aged adults who suddenly need reading glasses, patients with traumatic brain injuries, and people with visual disorders such as "lazy eye" may have one thing in common - "visual crowding," an inability to recognize individual items surrounded by multiple objects. Visual crowding makes it impossible to read, as single letters within words are rendered illegible. And basic cognitive functions such as facial recognition can also be significantly hampered. Scientists and clinicians currently attribute crowding to a disorder in peripheral vision.Now Prof. Uri Polat, Maria Lev, and Dr.
