Ultrasonics Improves Surgeons’ View When Removing Tumors From The Pituitary Gland

Ultrasonics improves surgeons’ view when they remove tumors from the pituitary gland. Hidden in a little hollow in the skull, at about the level of the eye, we have a gland about the size of a blackcurrant. This is the hypophysis, or pituitary, the body’s center for hormone manufacture. The gland produces a wide range of hormones which in turn control other organs that manufacture yet more...

Hybrid System Of Human-Machine Interaction Created

Scientists have created a "hybrid" system to examine real-time interactions between humans and machines (virtual partners). By pitting human against machine, they open up the possibility of exploring and understanding a wide variety of interactions between minds and machines, and establishing the first step toward a much friendlier union of man and machine, and perhaps even creating a different...

Key Target Of Aging Regulator Found

Researchers have defined a key target of an evolutionarily conserved protein that regulates the process of aging. The study provides fundamental knowledge about key mechanisms of aging that could point toward new anti-aging strategies and cancer therapies.

Super-computer Provides First Glimpse Of Earth's Early Magma Interior

By using a super-computer to virtually squeeze and heat iron-bearing minerals under conditions that would have existed when the Earth crystallized from an ocean of magma to its solid form 4.5 billion years ago, geochemists have produced the first picture of how certain forms of iron were initially distributed in the solid...

Lung Disease: Top Notch Decisions In The Developing Airways Bring Insights Into Lung Disease

In the normal lung, the airways are lined by a balanced mixture of ciliated, secretory and neuroendocrine cells which perform functions as diverse as air humidification, detoxification, and clearance of environmental particles. This balance can be altered dramatically by faulty adaptation responses of the lung to cigarette smoke or allergens in patients with chronic obstructive pulmonary disease...

Sediment Yields Climate Record For Past Half-million Years

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles...

3-D, Real-time X-ray Images May Be Closer To Reality

Three-dimensional, real-time X-ray images may be closer to reality. New work on a process called high-harmonic generation, or HHG. X-ray radiation can be created by focusing an optical laser into atoms of gaseous elements – usually low-electron types such as hydrogen, helium, or...

Advances In Medical Technology: What Does The Future Hold?

Major challenges and opportunities will arise in the health sector in the future. Although sophisticated medical technology is already available in health systems in developed countries, further advances are constantly being made. As a result of the addition of medical nanotechnology to existing knowledge of molecular and cellular biology, it seems likely that new, more personalized, more accurate...

Autistics Better At Problem-solving, Study Finds

Autistics are up to 40 percent faster at problem-solving than non-autistics, according to a new study published in the journal Human Brain Mapping. As part of the investigation, participants were asked to complete patterns in the Raven's Standard Progressive Matrices -- test that measures hypothesis-testing, problem-solving and learning...

Carl Linnaeus Invented The Index Card

Carl Linnaeus is most famous as the father of modern taxonomy. What’s not so well known is that in his effort to manage vast amounts of data, he came up with a revolutionary invention: the index card.

Cells Are Like Robust Computational Systems, Scientists Report

Gene regulatory networks in cell nuclei are similar to cloud computing networks, such as Google or Yahoo!, researchers report in the journal Molecular Systems Biology. The similarity is that each system keeps working despite the failure of individual components, whether they are master genes or computer...
