Optical Coherence Tomography Could Track Brain Shrinkage In MS Patients

Optical Coherence Tomography Could Track Brain Shrinkage In MS Patients

A five-minute eye exam might prove to be an inexpensive and effective way to gauge and track the debilitating neurological disease multiple sclerosis, potentially complementing costly magnetic resonance imaging to detect brain shrinkage - a characteristic of the disease’s progression.
A Johns Hopkins-based study of a group of 40 multiple sclerosis (MS) patients used a process called optical coherence tomography (OCT) to scan the layers of nerve fibers of the retina in the back of the eye, which become the optic nerve. The process, which uses a desktop machine similar to a slit-lamp, is simple and painless.

Organic Solar Cells: The Hype Has No Limit

Organic Solar Cells: The Hype Has No Limit

In the latest issue of Materials Today, Dr. Gilles Dennler of Konarka Austria GmbH and twenty other experts warn that a race to report organic solar cells (OSCs) with world record efficiencies is leading to a significant number of published papers claiming unrealistic and scientifically questionable results and performances.
“World record efficiencies are popping up almost every month, leading the OSC community into an endless and dangerous tendency to outbid the last report,” stated Dennler et al. in the article. “The current outbidding phenomenon does a severe disservice to the whole community, damaging its reputation.

Study: Feminists Are More Romantic

Study: Feminists Are More Romantic

It is generally perceived that feminism and romance are in direct conflict yet according to a study by Laurie Rudman and Julie Phelan of Rutgers University, feminism and romance are not incompatible and feminism may actually improve the quality of heterosexual relationships.
They carried out both a laboratory survey of 242 American undergraduates and an online survey including 289 older adults, more likely to have had longer relationships and greater life experience.

The Downside To Options-Heavy CEO Incentives

The Downside To Options-Heavy CEO Incentives

Legislation targeting companies has the best of intentions - preventing another Enron by Sarbanes-Oxley is an example - yet the punishment clauses have made it difficult to attract anyone except risk takers and has pushed CEO salary costs through the roof.
The opposite of the salary-heavy CEO is the one who takes options instead. On the exterior, it may seem to make sense because companies are paying solely for performance. More often than not, companies are paying no matter what.
A new study by Donald Hambrick of Penn State and W. Gerard Sanders of Brigham Young finds that CEOs with stock option-heavy compensation packages tend to lead their companies to more extreme performance yet they are more big losses than big gains.

'Good' Carbon Monoxide May Benefit Heart Patients

'Good' Carbon Monoxide May Benefit Heart Patients

Although nearly 500 people have died in the UK over the last 12 years as a result of accidental CO poisoning, small quantities of CO are produced naturally within the human body and are essential to life.
Chemists at the University of Sheffield have discovered an innovative way of using targeted small doses of CO which could benefit patients who have undergone heart surgery or organ transplants and people suffering from high blood pressure.
Although the gas is lethal in large doses, small amounts can reduce inflammation, widen blood vessels, increase blood flow, prevent unwanted blood clotting – and even suppress the activity of cells and macrophages ( macrophage cells are part of the human body’s natural defence system ) which attack transplanted organs.

Oxytocin in Pregnant Women Predicts Mother-Child Bond

Oxytocin in Pregnant Women Predicts Mother-Child Bond

Humans are hard-wired to form enduring bonds with others. One of the primary bonds across the mammalian species is the mother-infant bond. Evolutionarily speaking, it is in a mother’s best interest to foster the well-being of her child; however, some mothers just seem a bit more maternal than others do. Now, new research points to a hormone that predicts the level of bonding between mother and child.
In animals, oxytocin, dubbed “the hormone of love and bonding,” is critically important for the development of parenting, is elicited during sexual intercourse, and is involved in maintaining close relationships. Animals with no oxytocin exhibit slower pup retrieval and less licking and self-grooming.

Metamaterials 'Wrong' Light Bending May Be Oh So Right

Metamaterials 'Wrong' Light Bending May Be Oh So Right

A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

The Hospital Matters: Mortality 71 Percent Lower At Top Rated Ones

Patients have on average a 71 percent lower chance of dying at the nation’s top-rated hospitals compared with the lowest-rated hospitals across 18 procedures and conditions analyzed in the tenth annual HealthGrades Hospital Quality in America Study, issued today by HealthGrades, the healthcare ratings company.

ADHD And Working Memory

ADHD And Working Memory

Attention-deficit/hyperactivity disorder (ADHD), a state of serious impairments in both learning ability and social functioning, is one of many labels for one of the most prevalent conditions in child psychiatry, and, undoubtedly, the most controversial, which partly persists into adulthood. ADHD is conservatively estimated to occur in 3,0–7,5% of school-age children (Goldman et al., 1998), but more permissive criteria yield estimates of up to 17% (Barbaresi et al., 2002). Up to 20% of boys in some school systems receive psychostimulants for the treatment of ADHD (LeFever et al., 1999).

The Emotion Humans Notice First: Fear

The Emotion Humans Notice First: Fear

You may not be fully dressed without a smile, but a look of horror will make a faster first impression. Vanderbilt University researchers have discovered that the brain becomes aware of fearful faces more quickly than those showing other emotions.
"There are reasons to believe that the brain has evolved mechanisms to detect things in the environment that signal threat. One of those signals is a look of fear," David Zald, associate professor of psychology and a co-author of the new study, said.

Astrophysics 2020: Large Space Missions Beyond the Next Decade

Astrophysics 2020: Large Space Missions Beyond the Next Decade

On November 13-15 astronomers will meet at the "Astrophysics 2020: Large Space Missions Beyond the Next Decade" conference at the Space Telescope Science Institute in Baltimore, Md. to discuss the space observatories and science investigations that could be realized in the 2020-2030 decade.
Though the Hubble Space Telescope was launched in 1990, NASA started planning two decades earlier by establishing, in 1970, committees to plan the engineering of the space telescope and to determine the scientific goals of the mission.
The year 2020 is 13 years away, but astronomers now need to start envisioning astrophysics that could be accomplished from space in the 2020 era and beyond. Lead times of at least a decade are required for the most ambitious of space observatories.

The ‘Z-ring’ Helps Bacteria Cells Divide

The ‘Z-ring’ Helps Bacteria Cells Divide

In process that is shrouded in mystery, rod-shaped bacteria reproduce by splitting themselves in two. By applying advanced mathematics to laboratory data, a team led by Johns Hopkins researchers has solved a small but important part of this reproductive puzzle.
The findings apply to highly common rod-shaped bacteria such as E. coli, found in the human digestive tract. When these single-celled microbes set out to multiply, a signal from an unknown source causes a little-understood structure called a Z-ring to tighten like a rubber band around each bacterium’s midsection. The Z-ring pinches the rod-like body into two microbial sausages that finally split apart.
