Light used to regulate protein synthesis

Proteins are the puzzle-pieces of life, involved in how organisms grow and flourish, but studying their complex biological processes in living systems has been extremely difficult.

Scientists identify inhibitors of the anthrax toxin

A collaborative team of scientists led by The Burnham Institute's Maurizio Pellecchia, Ph.D., has identified inhibitors of the anthrax toxin, termed lethal factor ("LF") that could be developed into an emergency treatment for exposure to inhalation anthrax.

Finding may impact understanding of mechanical facets of many diseases

An international team led by Jeffrey J. Fredberg, professor of bioengineering and physiology at the Harvard School of Public Health, has found that the cell modulates its mechanical properties in much the same way as a glassblower shapes fine glassware.

Early embryos with abnormal chromosomes are capable of returning to normal when grown in culture in the laboratory

While such embryos are not capable of developing into normal foetuses if implanted in a woman's womb, the discovery has important implications for stem cell production, especially in countries where the creation of embryos for stem cell research is discouraged or even banned.

Unique arrays of proteins tethered onto self-assembled DNA nanostructures

In the fifty-year history since the structure of DNA was first revealed, what was once a Nobel prize- winning research discovery has become an omnipresent cultural icon co-opted for promoting everything from fragrances to musical acts.

New way of obtaining embryonic stem cells that avoids contamination by other types of cells

Scientists in the USA have discovered a new way of obtaining embryonic stem cells that avoids contamination by other types of cells and reduces the numbers of embryos needed to create embryonic stem cell lines.

Stem cells grown in lab mirror normal developmental steps

Johns Hopkins scientists have developed a way to study the earliest steps of human blood development using human embryonic stem cells grown in a lab dish instead of the embryos themselves.

British team grow sperm and eggs from stem cells

British scientists have made a major breakthrough with the discovery that both sperm and eggs can be grown from stem cells.

Scientists prove that human embryonic stem cells can develop in the laboratory into the early forms of cells that eventually become eggs or sperm

Their work opens up the possibility that eggs and sperm could be grown from stem cells and used for assisted reproduction, therapeutic cloning and the creation of more stem cells for further research and for the improved treatments for patients suffering from a range of diseases.

Australian scientists develop unique animal model for asthma

The State Government of Victoria, Australia has announced that Melbourne veterinary scientists have developed a unique animal model for asthma that may help drug companies fast track the creation of therapies for the disease.

Stem cells to solve blood shortage problems

The State Government of Victoria, Australia announced that Melbourne scientists at Monash University have developed a unique technology that can grow large numbers of blood cells from human embryonic stem cells.

New complete muscle grown in the lab

A multinational team of researchers has grown new muscle complete with its own network of blood vessels in the laboratory, and implanted the new muscle in a living mouse. The accomplishment is a first for tissue engineering, according to a report in the June 19 issue of Nature Biotechnology.

U.S. scientists have successfully engineered blood vessels from human vascular cells in the lab

Tissue engineering has made considerable progress in the past decade, but advances have stopped short of clinical application for most tissues. For elderly patients tissue-engineered arteries could provide grafts for bypass surgery.

Jumping genes help detemine uniqueness of individual brains

Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells.

Scientists discover new way of bringing "bio-prospecting" out of the rainforest and into the lab

Nature is a seemingly endless storehouse of interesting - and potentially life-saving - biological molecules. But tracking down and harvesting those chemicals in their natural form can be time-consuming, expensive and unreliable.

Nanotechnology used to smuggle a powerful chemotherapeutic drug inside tumor cells

University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells - increasing the drug's cancer-killing activity and reducing its toxic side effects.

US scientists find "mother of all brain stem cells"

Scientists at the University of Florida have been able grow brain cells in the laboratory.

Scientists create new brain cells - in a dish

Regenerative medicine scientists at the University of Florida's McKnight Brain Institute have created a system in rodent models that for the first time duplicates neurogenesis - the process of generating new brain cells - in a dish.

Bio-engineered skin provides clues to melanoma development

When it comes to the deadly skin cancer melanoma, studying functional tissue rather than cell lines may better provide insight into the disease's development, according to new research from a Howard Hughes Medical Institute predoctoral fellow at Stanford University School of Medicine.

If a dividing cell's activity is a pop song, then the same process in an immune cell is an extended-play dance remix

The basics of cell division are the same in both, but there's a heck of a lot more going on in immune cells, Johns Hopkins scientists have discovered.
