How dense is a cell?
CAMBRIDGE, Mass. More than 2,000 years after Archimedes found a way to determine the density of a king's crown by measuring its mass in two different fluids, MIT scientists have used the same principle to solve an equally vexing puzzle ' how to measure the density of a single cell. 'Density is such a fundamental, basic property of everything,' says William Grover, a research associate in MIT's Department of Biological Engineering.

Scientists reveal HIV weakness
CAMBRIDGE, Mass. Ever since HIV was revealed as the infectious agent behind the AIDS epidemic, scientists have been striving to develop a vaccine against the disease. However, the task has proven difficult, because HIV mutates so rapidly. In a new finding that may allow vaccine designers to sidestep part of that obstacle, researchers at the Ragon Institute of Massachusetts General Hospital, MIT and Harvard University have identified sections of an HIV protein where mutations would actually undermine the virus? fitness - its ability to survive and reproduce.

Lyme disease tick adapts to life on the (fragmented) prairie
The Lyme disease tick, seen here in its larval, nymph and adult forms, is advancing across "the prairie state." Photo by Illinois Natural History Survey CHAMPAIGN, lll. A new study offers a detailed look at the status of Lyme disease in Central Illinois and suggests that deer ticks and the Lyme disease bacteria they host are more adaptable to new habitats than previously appreciated.

‘Smart materials’ that make proteins form crystals to boost research into new drugs
‘Smart materials’ that make proteins form crystals to boost research into new drugs
Scientists have developed a new method to make proteins form crystals using 'smart materials' that remember the shape and characteristics of the molecule. The technique, reported today in Proceedings of the National Academy of Science , should assist research into new medicines by helping scientists work out the structure of drug targets.

Older people less likely to fall if they pay attention to their feet
Just as grey hair and wrinkles are widely accepted as a natural part of ageing, so is an increased risk of falling, which can happen for many reasons and with devastating consequences, including increased likelihood of injury, hospitalisation and even death. A new research study by human movement scientists at the University of Birmingham is seeking to reduce the risk to older people of falling, by investigating the relationship between gaze direction and walking behaviour.

New discoveries in diabetes
New discoveries in diabetes
[NEWS 21 June 2011] A new signal pathway that renders the insulin-releasing beta cell more sensitive to high levels of blood glucose has been discovered by researchers at Karolinska Institutet. A second new study reveals a possible way to delay the disease by inhibiting a lipoprotein. A new joint study published and conducted by researchers at Karolinska Institutet's Department of Molecular Medicine and Surgery and their American colleagues provides new insights into how beta cells react to raised concentrations of blood sugar, which occur, for example, after a meal.

Cutting edge training developed the human brain 80 000 years ago
Advanced crafting of stone spearheads contributed to the development of new ways of human thinking and behaving. This is what new findings by archaeologists at Lund University have shown. The technology took a long time to acquire, required step by step planning and increased social interaction across the generations.

Picower: 1 Skull + 2 Brains = 4 Objects in Mind
CAMBRIDGE, Mass. In the 1983 movie 'A Man with Two Brains,' Steve Martin kept his second brain in a jar. In reality, he had two brains inside his own skull - as we all do, one on the left and one on the right hemisphere. When it comes to seeing the world around us, each of our two brains works independently and each has its own bottleneck for working memory.

How we come to know our bodies as our own
How we come to know our bodies as our own
By taking advantage of a 'body swap' illusion, researchers at Karolinska Institutet have captured the brain regions involved in one of the most fundamental aspects of self-awareness: how we recognize our bodies as our own, distinct from others and from the outside world. That self-perception is traced to specialized multisensory neurons in various parts of the brain that integrate different sensory inputs across all body parts into a unified view of the body.

Prostate cancer circumvents hormone therapy by activating alternate signaling pathway
Cancer is crafty. When one avenue driving its growth is blocked by drugs targeting that path, the malignancy often creates a detour, finding an alternative route to get around the roadblock.

Gulf of Mexico Dead Zone Severely Impairs Reproduction In Atlantic Croaker, Researchers Find
AUSTIN, Texas — Atlantic croaker living in the large Gulf of Mexico "Dead Zone" exhibit severe reproductive impairment with potential long-term impacts on the fish's population abundance, researchers from The University of Texas at Austin's Marine Science Institute have found. Males and females were found to produce dramatically fewer sperm and eggs.

New cell type offers immunology hope
A team of Melbourne scientists has discovered a new type of cell in the immune system. The new cell type, a kind of white blood cell, belongs to a family of T-cells that play a critical role in protection against infectious disease. Their findings could ultimately lead to the development of novel drugs that strengthen the immune response against particular types of infectious organisms.

Brain scan identifies patterns of plaques and tangles in adults with Down syndrome
Brain scan identifies patterns of plaques and tangles in adults with Down syndrome
In one of the first studies of its kind, UCLA researchers used a unique brain scan to assess the levels of amyloid plaques and neurofibrillary tangles — the hallmarks of Alzheimer's disease — in adults with Down syndrome. Published in the June edition of the Archives of Neurology, the finding may offer an additional clinical tool to help diagnose dementia in adults with Down syndrome, a genetic disorder caused by the presence of a complete or partial extra copy of chromosome 21.

Group therapy helps MS sufferers cope with depression, study finds
PA 184/11 Offering Multiple Sclerosis sufferers emotional support through group therapy sessions could improve their quality of life and save the NHS almost £500 per patient, a study at The University of Nottingham has discovered. Researchers are now planning a larger multi-centre study into the issue to establish whether psychological therapy should be incorporated into the MS services currently provided by the NHS.

Cancer survivors spend more on health care
University Park, Pa. Approximately 12 million people in the United States are cancer survivors. On average, their medical care costs $4,000 to $5,000 more annually than the care of people who have never had cancer, according to Penn State researchers. Those who are treated for and survive cancer are susceptible to later health complications and their total medical expenses average about $9,300 per year.

Nanoparticles may help inhibit Alzheimer’s disease and other neurodegenerative disorders
ANN ARBOR, Mich.—Nanoparticles of the right dimensions and shape may be the key in combating the plaque that destroys neurons and leads to symptoms associated with Alzheimer's disease, a new report shows. University of Michigan chemical engineering professor Nicholas Kotov says the nanotechnology means can attract and capture the longer fibrils that are known to form plaque related to neurodegenerative disorders.
