Scientists have developed a fast and safe method for collecting heart stem cells from small amounts of biopsied heart tissue

In human and animal studies, scientists at Johns Hopkins have developed a fast and safe method for collecting heart stem cells from remarkably small amounts of biopsied heart tissue (15 mg or less), and growing the cells in the lab to get more.

Scientists have found a fossil that explains the history of the nose

Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve?

Reproductive hormones have effects on all of these stages of brain growth and development

Scientists are now uncovering increasing evidence that the brain not only responds to hormones produced by the reproductive system, but that these hormones-the so-called "female hormones," estrogen and progestin, and the "male" androgens, such as testosterone-play an important role in the development of differences between male and female brains.

Grant to develop high speed DNA sequence reader

Sequencing of the human genome is one of the major scientific advances of our time. But with 3 billion base pairs, initial sequencing of the human genome took 11 years and cost $1 billion to complete in 2002. Today, it costs up to $50 million to sequence 3 billion base pairs.

Cellular enzyme represents a potential new target for developing improved HIV drugs

Scientists have discovered that a cellular enzyme helps ferry HIV genetic instructions out of the cell nucleus where they can then be translated into proteins to begin their most destructive work.

Scientists decode the genome sequence of Cryptosporidium hominis, one of the most common causes of waterborne diseases in humans

A team of scientists at Tufts University School of Veterinary Medicine has helped decode the genome sequence of Cryptosporidium hominis, an insidious parasite identified as one of the most common causes of waterborne diseases in humans and classified by the Centers for Disease Control and Prevention as a potential bioterrorist agent.

Genetic double-agents unmasked

Babraham Institute and Cancer Research UK scientists have discovered that certain enzymes with a key activity in the immune system may be important in stem-cell development, but may also work against us by contributing to the occurrence of cancer.

Dolphins brain size helps to provide some answers to how the species evolved in relation to humans

The intelligence and cognitive capabilities of dolphins and their aquatic cousins have long fascinated the public and the scientific community, but the question of how and why they have such large brains has mostly gone unanswered.

Australian platypus research has implications for understanding the evolution of human sex determination

The mystery surrounding sex determination of the unique Australian platypus has yielded a surprising secret: it has 10 sex chromosomes.

Discovery of new protein involved in regulating the second most commonly mutated tumor suppressor in human tumors

Scientists in Tokyo have discovered a new protein, named PICT-1, that is involved in regulating PTEN, the second most commonly mutated tumor suppressor in human tumors.

Researchers trim count of human genes to 20,000-25,000

Scientific description of the finished human genome sequence, reducing the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species.

Nano-bullet for non-invasive treatment of cancers

Virginia Commonwealth University physicists, working with one of the most precious materials on Earth – gold -- and with one of the most common – sand -- have created a so-called “nano-bullet” that targets tumors and may help scientists develop non-invasive cancer treatments.
