Biologists have identified the specific region in vertebrates where adult blood stem cells arise during embryonic development. The researchers say their time-lapse imaging of the process, by which primitive embryonic tissues first produce the parent stem cells that produce all adult blood cells over the life of an individual, should help guide future efforts to [...]

How does a single-celled organism, one of the simplest life forms on Earth, manage to satisfy its nutritional needs? It is by studying social amoebae, elementary organisms that are distantly related to fungi and plants, that researchers in France have, for the first time, demonstrated the nutritional preferences of such systems. Despite lacking a centralizing [...]

Glaucoma patients who take medication for the condition appear to have a reduced likelihood of death, according to a new study.
A robot that can be programmed to have a range of medical conditions, from heart disease to constipation, is being used by Pharmacy students to help practice diagnostic skills and treating patients The SimMan 3G, dubbed “Simon” by the students, i.s a life-sized model that talks, breathes and reacts to medicines in the same way [...]

Factors such as maternal high blood pressure and high hematocrit levels (the proportion of blood that consists of red blood cells) are associated with a greater likelihood of restricted fetal growth during the first trimester, with restricted growth linked to an increased risk of preterm birth and low birth weight, according to a new study.

Dedicated biomass gasification technologies are presently being developed in many countries for the production of second-generation liquid biofuels. Both fluidized-bed gasification and special entrained flow systems are under intensive development. These technologies can also be used for hydrogen production, which may become an interesting alternative in replacing part of fossil fuel input in oil refineries [...]
Researchers have found a direct link between neighborhood socioeconomic status and risk for type 2 diabetes in African American women. The study is the first prospective study to examine the relationship between neighborhood socioeconomic status and incidence of type 2 diabetes in a large, geographically diverse cohort of African-American women.

By creating diamond-based nanowire devices, scientists have taken another step towards making applications based on quantum science and technology possible. The new device offers a bright, stable source of single photons at room temperature, an essential element in making fast and secure computing with light practical.
Scientists have discovered a potential new use for the drug closantel, currently the standard treatment for sheep and cattle infected with liver fluke. The new research suggests that the drug may be useful in combating river blindness, a tropical disease that is the world’s second leading infectious cause of blindness for humans.

Wholegrain bread is good and good for you, as most people know. But it is not only the fiber-rich bran, the outer shell of the grain, that is healthful. On the contrary, new research shows that bread baked with white rye flour, which is flour made from the inner, white part of the rye kernel, [...]
