    Ancient Egyptian Science

    There was no word known to us from ancient Egypt with the specific meaning of "science". The word Rh, "to know" probably comes closest, but it had a wide range of meanings. This is perhaps understandable, as our current definition of science is rather broad. We define it as the observation, identification, description, experimental investigation and theoretical explanation of phenomena. Otherwise, it is knowledge, especially gained through experience. Knowledge itself was the domain of the god Thoth in ancient Egypt, who was the patron deity of scribes. It was the scribes who were almost exclusively responsible for ancient Egyptian science, usually in either a priestly role, or that of administrators.

    Scientists identify potential drug target for treatment-resistant anemias

    Researchers at Whitehead Institute have identified a protein that is the target of glucocorticoids, the drugs that are used to increase red blood cell production in patients with certain types of anemia, including those resulting from trauma, sepsis, malaria, kidney dialysis, and chemotherapy. The discovery could spur development of drugs capable of increasing this protein's production without causing the severe side effects associated with glucocorticoids.

    "This research is medically important, and we are using it to find a better way to increase the production of red blood cells for these patients," says Harvey Lodish, who is a Whitehead Institute Founding Member and a professor of biology at MIT. "It is also a new insight into how self-renewal in stem cells can be controlled, and a new way to think about how we can use an RNA binding protein to maintain stem and progenitor cells."

    Life’s Blood: Angiogenesis in Health and Disease

    Our cells need oxygen and nutrients to survive. The cells of very small organisms can obtain what they need from the environment by simple diffusion, in which nutrients and gases pass from areas of high concentration to low concentration through cell membranes. But diffusion isn’t very useful over distances greater than a millimeter or so. Larger animals, including humans, need a vascular system, a way for the oxygen and nutrients to get from the outside environment to every cell in the body (and for carbon dioxide and waste products to get back out to the environment).

    Modern food biotechnology, human health and development: an evidence-based study

    This study was commissioned by the World Health Organization (WHO) to establish a knowledge base for evaluating the application of modern biotechnology in food production. The study does not seek to address all issues and evidence in detail, but rather aims to place in context the overall impact of this technology on human health and development. The study reviews evidence in several broad areas related to the use of genetically modified (GM) organisms in the food supply (GM foods), including a review of GM food products currently available, the assessment of risks and benefits, the broader impact on societies, and the existing regulatory capacity in countries. The evidence was collected and collated by WHO with the support of a background group of external experts (list of experts - annex 1). Data for the study were gathered through traditional methodology as well as through an open questionnaire and an Internet-based electronic discussion process. Preliminary results were discussed at a broad stakeholder meeting held in 2003 (list of participants - annex 1), informing further data search and revision.
