Baltimore, MD—Since Carnegie Institution’s Barbara McClintock received her Nobel Prize on her discovery of jumping genes in 1983, we have learned that almost half of our DNA is made up of jumping genes—called transposons. Given their ability of jumping around the genome in developing sperm and egg cells, their invasion triggers DNA damage and mutations.

Carnegie’s Department of Embryology scientist Steven Farber and team have been awarded a 5-year $3.3-million NIH grant to identify novel pharmaceuticals for combating a host of diseases associated with altered levels of lipoproteins like LDL (“bad cholesterol”). Obesity, diabetes, cardiovascular disease, fatty liver disease, and metabolic syndrome have all been linked to changes in plasma lipoproteins.

Baltimore, MD— Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie’s Rebecca Obniski, Matthew Sieber, and Allan Spradling.

Ethan Greenblatt, a senior postdoctoral associate in Allan Spradling’s lab at the Department of Embryology, has been awarded the eleventh Postdoctoral Innovation and Excellence Award. Greenblatt has made a major impact on biological science, particularly with his research identifying genetic factors underlying fragile X syndrome, the most common cause of autism.

Baltimore, MD—The Pew Charitable Trust has awarded Carnegie’s Steve Farber and colleague John F. Rawls of Duke University a $200,000 grant to investigate how dietary nutrients, such as fats, alter the ability to sense glucose in the gut—a process that involves the microbial ecosystem in the gut.

Baltimore, MD—New work from Carnegie’s Ethan Greenblatt and Allan Spradling reveals that the genetic factors underlying fragile X syndrome, and potentially other autism-related disorders, stem from defects in the cell’s ability to create unusually large protein structures.

Baltimore MD—Almost half of our DNA sequences are made up of jumping genes—also known as transposons. They jump around the genome in developing sperm and egg cells and are important to evolution. But their mobilization can also cause new mutations that lead to diseases, such as hemophilia and cancer.

Baltimore, MD—A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. One of the biggest challenges in biology is to understand how certain regions of this highly packaged DNA can be called upon, so that the genes encoded in them can be “turned on,” or expressed and used to manufacture RNA and proteins.

Baltimore, MD—Allan C. Spradling, Director Emeritus of Carnegie’s Department of Embryology, has been awarded the 23rd March of Dimes and Richard B. Johnson, Jr., MD Prize in Developmental Biology as “an outstanding scientist who has profoundly advanced the science that underlies our understanding of prenatal development and pregnancy.”

Washington, DC—Not too long ago, biologists would induce mutations in an entire genome, isolate an organism that displayed a resulting disease or abnormality that they wanted to study, and then work backward to determine which gene was responsible for the defect.  This process often took years to yield definitive results.

Baltimore, MD— The brain is the body’s mission control center, sending messages to the other organs about how to respond to various external and internal stimuli. Located in the forebrain, the habenular region is one such message-conducting system. Two new papers from Carnegie scientists explain how the habenulae develop and their unsuspected role in recovering from fear.

Baltimore, MD—Studying how our bodies metabolize lipids such as fatty acids, triglycerides, and cholesterol can teach us about cardiovascular disease, diabetes, and other health problems, as well as reveal basic cellular functions. But the process of studying what happens to lipids after being consumed has been both technologically difficult and expensive to accomplish until now.

Baltimore, MD—A first-of-its-kind study on almost 20,000 K-12 underrepresented public school students shows that Project BioEYES, based at Carnegie’s Department of Embryology, is effective at increasing students’ science knowledge and positive attitudes about science. Younger students had the greatest attitude changes. The study covered five years and tested students before and after the one-week BioEYES program.
