Helping Those with Dysthymic Depression

Clinical depression is an epidemic that is diagnosed in over 9 million Americans each year–a marginal amount of the real number it affects, since most Americans never seek medical aid for clinical depression.

A better test to detect DNA for diagnosing disease, investigating crimes

Researchers in Singapore are reporting development of a new electronic sensor that shows promise as a faster, less expensive, and more practical alternative than tests now used to detect DNA.

Faster, more cost-effective DNA test for crime scenes, disease diagnosis

The new method could lead to expanded use of PCR in medicine, the criminal justice system and elsewhere, the researchers say.

Comparing sequences without using alignments: application to HIV/SIV subtyping

In general, the construction of trees is based on sequence alignments. This procedure, however, leads to loss of informationwhen parts of sequence alignments (for instance ambiguous regions) are deleted before tree building.

Real-time phase-contrast x-ray imaging: a new technique for the study of animal form and function

This technique takes advantage of partially-coherent x-rays and diffraction to enable clear visualization of internal soft tissue not viewable via conventional absorption radiography.

Fast and non-invasive PCR sexing of primates: apes, Old World monkeys, New World monkeys and Strepsirrhines

One of the key tools for determining the social structure of wild and endangered primates is the ability to sex DNA from small amounts of non-invasive samples that are likely to include highly degraded DNA.

New technique can be breakthrough for early cancer diagnosis

Early detection of disease is often critical to how successful treatment can be.

Basis created for directing and filming blood vessels

A new method of filming blood-vessel cells that move in accordance with targeted signals has been developed by researchers at Uppsala University in collaboration with researchers at the University of California.

Using high-precision laser tweezers to juggle cells

Researchers at the University of Gothenburg, Sweden, have developed a new method to study single cells while exposing them to controlled environmental changes.

Scientists use lasers to measure changes to tropical forests

New technology deployed on airplanes is helping scientists quantify landscape-scale changes occurring to Big Island tropical forests from non-native plants and other environmental factors that affect carbon sequestration.

Sequencing method yields fuller picture

Sequence data for both chromosomes can be inferred under the right circumstances, USC biologists say.

Counting semi-viable bacteria in cheese

The Wageningen researcher Christine Bunthof has developed a direct method for counting bacteria in dairy products.

New tool cracks genomic code quicker than ever

US and Australian scientists have pioneered a new hybrid method for genomic sequencing that is faster and cheaper than state of the art technologies.

No more test tubes on four feet? EPA moves toward animal-free toxicity tests

The U.S. Environmental Protection Agency (EPA) plans to switch to a new generation of animal-free tests for predicting the toxicity of chemicals to humans

New biosensor for most serious form of Listeria food poisoning bacteria

Scientists in Indiana are reporting development of a new biosensor for use in a faster, more sensitive test for detecting the deadliest strain of Listeria food poisoning bacteria.

Troubleshooting: Cell Culture

A table below addresses some of the common problems encountered when culturing cells, along with their possible causes and suggested solutions.

Nothing to sneeze at: Real-time pollen forecasts

Researchers in Germany are reporting an advance toward development of technology that could make life easier for millions of people allergic to plant pollen.

A faster test for the food protein that triggers celiac disease

Researchers in Spain and the United Kingdom are reporting development of a faster test for identifying the food protein that triggers celiac disease.

Toward a safer, more effective method for preserving museum specimens

Researchers now are reporting progress toward a safer, more effective method of preserving these precious biological specimens in order to prolong their study and enjoyment for future generations

DNA fingerprinting method may thwart false labeling of shark meat

Researchers in Spain are reporting that a new DNA identification method could thwart false labeling of shark species used in various seafood products...
