Good cholesterol to treat diseases.

A new type of “good cholesterol,” made in the lab, could one day deliver drugs to where they are needed in the body to treat disease or be used in medical imaging, according to scientists. The high-density lipoprotein (HDL) mimic is easy to make in large amounts. Researchers Zahi A Fayad, Robert Langer, YongTae (Tony) Kim, Francois Fay, Willem Mulder and colleagues explained that HDL is a natural nanoparticle that carries cholesterol throughout the body.

Scientists discover metallic carbon

Scientists discover metallic carbon

3D Metallic carbon with interlocking hexagons.

A theoretical, three-dimensional (3D) form of carbon that is metallic under ambient temperature and pressure has been discovered by an international research team.Carbon science is a field of intense research. Not only does carbon form the chemical basis of life, but it has rich chemistry and physics, making it a target of interest to material scientists. From graphite to diamond to Buckminster fullerenes, nanotubes and graphene, carbon can display in a range of structures. But the search for a stable three-dimensional form of carbon that is metallic under ambient conditions, including temperature and pressure, has remained an ongoing challenge for scientists in the field. Read More

 

Engineered bacteria to synthesize drugs, biofuels

Engineered bacteria to synthesize drugs, biofuels

Kristala Jones Prather, Associate Professor, MIT.

Kristala Jones Prather, Associate Professor, MIT designed new ways to engineer bacteria to synthesize useful chemical compounds such as drugs and biofuels. Have been worked at Merck, Prather worked in many different areas, including biocatalysis — the use of bacterial enzymes to perform a reaction step that cannot be done cost-effectively using traditional chemical processes. Prather would develop an enzyme-driven reaction that could take place inside a cell, then send the resulting compound back into the chemical manufacturing process.Read More
