Scientists develop new way for exploring the insides of living cells

Scientists in Washington, DC, are reporting development and successful tests of a new way for exploring the insides of living cells, the microscopic building blocks of all known plants and animals. They explode the cell while it is still living inside a plant or animal, vaporize its contents, and sniff. The study appears in online in ACS' journal Analytical Chemistry.

NIDA supports new drug detection research

Every time a person snorts cocaine, it doesn't just go to his or her head: It also provokes a response in the immune system, creating special biomolecules that may serve as a permanent record of each exposure.

Researchers develop new molecular tools to investigate Alzheimer's disease

One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties.

Researchers discover new bend in gene control

Since the completion of the human genome sequence, a question has baffled researchers studying gene control: How is it that humans, being far more complex than the lowly yeast, do not proportionally contain in our genome significantly more gene-control proteins?

Researchers develop a new test process for cancer drugs

It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at the Technische Universitaet Muenchen (TUM) have developed a new test process for cancer drugs.

Controlled formation of patchy particles may serve as drug-delivery vehicles to combat disease

Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.

Researchers succeed in engineering human tissue patches from stem cells

University of Washington (UW) researchers have succeeded in engineering human tissue patches free of some problems that have stymied stem-cell repair for damaged hearts.

Scientists develop new molecule that can deliver genetic-based drugs into cells

Theresa M. Reineke, associate professor of chemistry in the College of Science, and colleagues in her lab at Virginia Tech and at the University of Cincinnati have developed a new molecule that can travel into cells, deliver genetic cargo, and packs a beacon so scientists can follow its movements in living systems.

Latest optical and laser technology in medicine displayed at FiO meeting

From scopes that help premature babies breathe to techniques for imaging live neurons and beating hearts as they develop, the latest optical and laser technology being deployed in medicine and the biosciences will be on display at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO), which takes place Oct. 11-15 at the Fairmont San Jose Hotel and the Sainte Claire Hotel in San Jose, Calif.

Researchers uncover evolutionary ancestry of prion gene

A University of Toronto-led team has uncovered the evolutionary ancestry of the prion gene, which may reveal new understandings of how the prion protein causes diseases such as bovine spongiform encephalopathy (BSE), also known as "mad cow disease."

Aptamer nanoflares for molecular detection in living cells

By combining a gold nanoparticle with a unique family of nucleic acids, researchers at Northwestern University have created a new type of intracellular reporting system that with a flash of light reveals the presence and quantity of a wide variety of biologically important molecules. These so-called nanoflares could provide cancer biologists with a highly sensitive method of tracking complex biochemical processes in real time without interfering with those processes.

ROS in cells contributes to aging

With all the hype about beneficial antioxidants in everything from face cream to cereal bars, you'd think their targets---oxygen radicals---must be up to no good. It's true, the buildup of oxygen radicals and other reactive oxygen species (ROS) in cells contributes to aging and possibly to diseases such as cancer and Alzheimer's.

Researchers to analyse nanoparticles

Researchers at Swansea University's Centre for NanoHealth have been awarded £1 million by the Research Councils' Nanoscience through Engineering to Application cross-council programme, led by the Engineering and Physical Science Research Council (EPSRC), to analyse the levels at which nanoparticles can be deemed safe within cells.

New genetic mechanism to control body's fat-building process identified

At a time of alarming increases in obesity and associated diseases -- and fiery debates about the cost of health care -- a UCF research team has identified a new genetic mechanism that controls the body's fat-building process.

New "micropatterning" method useful in gene expression studies

Like oil and water, two water-based liquids can mingle without mixing in a new University of Michigan technology developed for biological experiments.

New strategy for inhibiting virus replication

Viruses need living cells for replication and production of virus progeny. Thus far, antiviral therapy primarily targets viral factors but often induces therapy resistance. New improved therapies attempt to targets cellular factors that are essential for viral replication.

Living cells controlled with light; potential for stem cell research

University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. That ability to optically steer cells could be a major step in harnessing the healing power of stem cells and guiding them to areas of the body that need help.
