Gene regulation drives evolution

It is not just what's in your genes, it's how you turn them on that accounts for the difference between species , at least in yeast , according to a report by Yale researchers in this week's issue of Science.

How cells change the pace of their steps

Scientists at UC San Diego have discovered how cells of higher organisms change the speed at which they move, a basic biological discovery that may help researchers devise ways to prevent cancer cells from spreading throughout the body.

New understanding of adult stem cell regulation

Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells.

Simple method to comb genomes

Instead of immutable proprietary software, any species, genetic information resembles open source code that is constantly tweaked and optimized to meet the users specific needs.

Jefferson scientist shares patent for DNA analysis

A basic scientist in the Department of Surgery at Jefferson Medical College and the Kimmel Cancer Center at Jefferson has shared a patent on what may someday be a ubiquitous tool in DNA analysis.

New data about the laws governing embryo development in organisms

Research aimed at understanding the mechanisms underlying embryo development has taken a step forward thanks to collaborative work between biologists specialized in the study of the fruit fly (Drosophila melanogaster) and scientists specialized in the design of mathematical models that simulate the functioning of biological systems.

New genetic function involved in embryo development in organisms

Rapid evolution of defense genes in plants may produce hybrid incompatibility

One of the basic tenets of evolution is speciation in which populations of the same species become so genetically and morphologically variable that they can be classified as two different species.

Novel cellular mechanism that may guide cell movement and possibly cancer cell invasion

Scientists have long thought that microtubules, part of the microscopic scaffolding that the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome.

Molecular motors may speed nutrient processing

Matthew Tyska, Ph.D., recalls being intrigued, from the first day of his postdoctoral fellowship in 1999, with a nearly 30-year-old photograph.

Stem cells may look malignant, not act it

Call it the cellular equivalent of big glasses, a funny nose and a fake mustache.

24 May 2007

Cancer cells can be killed by a new cancer drug that is triggered by a laser light

Their paper describes how these new photosensitizer drugs can only be activated by light once they have been localized in the target tumour cells. For the first time Zheng and Wilson have demonstrated that tumour cells can be selectively attacked using a PDT.

It is highly unlikely that older women generate new eggs

Tilly reported the discovery of stem cells capable of migrating from bone marrow to mouse ovaries and generating new eggs there. The research fueled hopes that a new treatment - such as bone marrow transplantation - might one day help older women regain their fertility.

New mapping technique will answer fundamental questions about chromosome structure

Researchers at the University of Illinois have developed a simple and economical technique for imaging and mapping fruit fly chromosomes.

Headaches may act like tiny transient strokes

Migraines may be doing more than causing people skull-splitting pain. Scientists have found evidence that the headaches may also be acting like tiny transient strokes, leaving parts of the brain starved for oxygen and altering the brain in significant ways.

Study of planarians offers insight into germ cell development

The planarian is not as well known as other, more widely used subjects of scientific study , model creatures such as the fruit fly, nematode or mouse.

Researchers identify key function of a molecule - wound healing in the skin

The skin is the largest organ of the human body. It protects against environmental influences and pathogens, regulates body temperature, and protects the body against dehydration.

Junk DNA plays a role in controlling when genes turn on and off

Large swaths of garbled human DNA once dismissed as junk appear to contain some valuable sections, according to a new study by researchers at the Stanford University School of Medicine and the University of California-Santa Cruz.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

UT Metroplex institutions to collaborate on biomedical research

Researchers from the three University of Texas campuses in the Dallas-Fort Worth metropolitan area are combining their expertise in biomedical science, engineering and physical sciences on projects aimed at solving real-world medical problems.
