New molecular sensor could identify zinc-related diseases

Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes. The research, published today in Nature Methods, opens the door to the hidden world of zinc biology by giving scientists an accurate way of measuring the concentration of zinc and its location in cells for the first time.

IBM scientists image the anantomy of a molecule using noncontact atomic force microscopy

IBM scientists have been able to image the "anatomy" -- or chemical structure -- inside a molecule with unprecedented resolution, using a complex technique known as noncontact atomic force microscopy.

More than 22,000 Americans expected to be diagnosed with a malignant brain tumor in 2009

It is expected that more than 22,000 Americans will be diagnosed with a malignant brain tumor in 2009. Senator Ted Kennedy's death from a brain cancer draws attention to a rare, but often fatal type disease. While the risk of developing brain cancer is relatively low, it is important to heed the warning signs and receive an accurate diagnosis.

Scientists find another mechanism that destroys tumor cells

Cells don't like to be alone. In the early stages of tumor formation, a cell might be pushed out of its normal home environment due to excessive growth. But a cell normally responds to this homeless state by dismantling its nucleus, packing up its DNA, and offering itself to be eaten by immune system cells. Simply put, the homeless cell kills itself. This process, known as apoptosis, typically stops potential cancer cells before they have a chance to proliferate.

High cost of Tennessee's state program under the reform microscope

TennCare, the plan enacted in the mid-1990s to cover the Tennessee's uninsured through a public insurance program which nearly bankrupted the state, is fueling national debate about a public option, The Wall Street Journal reports.

Giant pituitary adenoma can be safely removed through nasal route

It’s even worse than being told you have a brain tumor: having a tumor so large, it’s in a category all its own. Giant pituitary adenoma is a so-called “benign” tumor that can cause visual loss and impair many of the body’s most basic functions. But fortunately, even the largest of these giant tumors—which can grow to the size of an egg and invade nearby structures--can be treated effectively using a multimodality approach starting with minimally invasive surgery through the nose, according to a new study at the John Wayne Cancer Institute at Saint John’s Health Center.

Holography helps tackle ovarian cancer

Two University of Arizona researchers have formed a research team to design, build and evaluate two versions of an ovarian cancer medical imaging and screening instrument that will use holographic components in a new type of optical microscope.

Recruitment of new neurons slows when old brain cells kept from dying

Recruitment of new neurons slows when old brain cells kept from dying. Like clockwork, brain regions in many songbird species expand and shrink seasonally in response to hormones.

New kind of “molecular condom” to protect women from AIDS

University of Utah scientists developed a new kind of “molecular condom” to protect women from AIDS in Africa and other impoverished areas. Before sex, women would insert a vaginal gel that turns semisolid in the presence of semen, trapping AIDS virus particles in a microscopic mesh so they can’t infect vaginal cells.

$1 million grant to Rhode Island hospital for melanoma screening training program

Rhode Island Hospital dermatologist Martin Weinstock, MD, PhD, has received a $1 million, 2-year Team Science Award grant from the Melanoma Research Alliance to serve as principal investigator to develop a training program for primary care physicians to improve melanoma screening in primary care. The goal is to develop a web-based training module that will lead to earlier detection of melanoma and ultimately reduce the number of melanoma deaths by half.

Stem cell technology innovation could reduce the number of animal experiments

Researchers from the University of Bath are embarking on a project to use stem cell technology that could reduce the number of animal experiments used to study conditions such as motor neurone disease.

New bio-hybrid materials could be used as sensors, catalysts, drug-delivery systems, more

Bacteria play a role in myriad industrial processes from fermentation to cleaning up environmental pollution. But floating freely in solution, the microbial cells constantly multiply, generating biomass that must be removed periodically, causing downtime. Additionally, the microorganisms cannot be localized to a specific region of interest.

New technique captures bacterial infection on film

Researchers have developed a new technique that allows them to make a movie of bacteria infecting their living host.

University at Buffalo start-up provides innovative digital sperm analysis to infertile couples worldwide

Couples struggling with fertility problems have a new option for assessing their ability to have a child with the start-up of a new Buffalo-based company called LifeCell Dx, Inc. (LCDX).

Camera-phone uses blood, saliva samples to diagnose disease

Researchers at the University of California, Berkeley, have developed a "prototype camera-phone mounted with a microscope" that can "magnify and photograph blood or saliva samples" for diagnosing diseases, the Canadian Press/Google.com reports.

Migrant neuron: New imaging studies reveal mechanics of neuron migration

The development of the brain proceeds a little like the European settlement of North America. The earliest pioneers settled on the east coast with subsequent waves of settlers forming communities further and further westward. In cortical regions of the developing brain, generations of young neurons undergo a staged migration as well, with the earliest-born cells staying relatively close to their birthplace and subsequent generations traveling further, ultimately stratifying into six neuronal layers in the mature brain. Now, for the first time, imaging studies have identified the "motors" that propel a unique form of cell migration that creates these layers that

IRIN examines efforts to improve sleeping sickness dectection

IRIN examines the efforts of the Geneva-based Foundation for Innovative New Diagnostics (FIND) to develop less costly surveillance equipment to improve the ability to detect the parasitic disease trypanosomiasis (sleeping sickness) in endemic countries.

Identification of cholesterol regulating genes by targeted RNAi-screening

Scientists at the European Molecular Biology Laboratory (EMBL) and the University of Heidelberg, Germany, have come a step closer to understanding how cholesterol levels are regulated. In a study published today in the journal Cell Metabolism, the researchers identified 20 genes that are involved in this process. Besides giving scientists a better idea of where to look to uncover the mechanisms that ensure cholesterol balance is maintained, the discovery could lead to new treatments for cholesterol-related diseases.
