Four Rockefeller Science Outreach students are finalists in Intel Science Talent Search

Four out of the 10 Science Outreach students who reached the semifinalist stage in the Intel Science Talent Search, have been named finalists: Evan Fink, Adam Kahn, Chrisann Kyi and Eugene Simuni. Only 40 finalists are named each year. In March the finalists will travel to Washington, D.C., to participate in a week-long competition. Ten winners will be announced at a black-tie dinner on Mon., Mar. 13, and will receive scholarships ranging from $20,000 to $100,000. The remaining 30 finalists will each receive a $5,000 scholarship. More »

Understanding Drive: Rockefeller researchers uncover the molecular mechanisms of sexual motivation

For most people, sex is a complicated topic. A new book by RU Professor Donald Pfaff, however, is based on the idea that the primitive, biological side of sex is explainable–at least from a scientific point of view. Pfaff’s lab researches the neurobiological and molecular aspects of sexual motivation. In Drive (MIT Press), he shows that the biological basis for sex drive–one of the most primitive human instincts–is largely explained by mechanisms uncovered in animal brains that have not changed in millions of years of evolution.

Rockefeller researchers show testosterone reduces level of Alzheimer’s proteins

Testosterone supplementation in elderly men may be protective in the treatment of Alzheimer’s disease, according to the results of a new study reported by researchers at Rockefeller University. Findings from epidemiological studies have indicated that estrogen-replacement therapy in postmenopausal women may protect against the development of the disease in a similar way. The research is reported in the Feb. 1 issue of the Proceedings of the National Academy of Science. More »

Ten Science Outreach students reach semifinals of Intel Science Talent Search

Ten out of the 60 high school students who participated in RU’s Science Outreach Program have been named semifinalists in the Intel Science Talent Search (formerly the Westinghouse Science Talent Search). This program, now in its 59th year, is one of the most prestigious science awards for high school students in the country. More than 70 percent of the former finalists have gone on to earn Ph.D.s or M.D.s; five have won Nobel Prizes. More »

Rockefeller University researchers shed light on brain disorder

A rare but devastating neurological disorder may be caused partly by immune-system cells that are spurred into action against tumors elsewhere in the body and eventually attack the brain, Rockefeller University researchers report. The scientists also found that the neurological damage from these cells, called cytotoxic T lymphocytes (CTLs), might be lessened by giving patients an immunosupressant drug. More »

Rockefeller University researchers find molecule that controls the balance between bone creation and bone destruction

Researchers at The Howard Hughes Medical Institute at The Rockefeller University have identified a novel molecular mechanism by which a molecule called TRANCE controls the balance between bone formation and bone destruction. The research, published in the Dec. 22 issue of the journal Molecular Cell, provides long-sought-after answers to questions about bone metabolism and has important implications in the treatment of bone diseases such as osteoporosis and rheumatoid arthritis.

RU researchers find that waking experiences influence the brain’s gene expression during REM sleep

Mammals spend a large portion of their lives sleeping. In addition to allowing the body to rest, sleep seems to play a role in the consolidation of daytime memories. A number of scientific observations have supported the idea that the brain is reactivated during sleep to process sensorimotor information, but how the brain did this remained unknown. In a recent paper in Learning & Memory, a team of Rockefeller scientists show that the expression of a gene linked to the modification of neuronal connections went up during the deepest phase of sleep that follows an enriched waking experience. The team suggests that this could provide a mechanism by which sleep contributes to the consolidation of memories of daytime events. More »

No Viral Rebound After Stopping Drugs: An Anomalous Group of HIV Patients

An unusual group of HIV-infected patients who stopped taking antiviral drugs yet continued to suppress HIV replication may have somehow boosted their immune response against the virus by temporary therapy interruptions, researchers from the Aaron Diamond AIDS Research Center at Rockefeller University report. Although scientists strongly advise against halting drug therapy–because the virus usually comes surging back–this observation suggests that some HIV-infected people can suppress the virus without drugs if they have strong immune responses.

Rockefeller and Aaron Diamond Researchers Say Resistance to HIV Drugs May Be Higher Than Previously Thought

A study of patients infected with the AIDS virus revealed that about one in six was carrying a strain that is resistant to at least one of the drugs targeting HIV, researchers report from the Aaron Diamond AIDS Research Center, an affiliate of The Rockefeller University. Lead author Daniel Boden, M.D., and 11 colleagues report the research as the cover story in the Sept. 22-29 issue of the Journal of the American Medical Association. The authors suggest that further research should try to establish whether AIDS therapy structured around HIV-resistance testing would be more effective than current methods. More »

Rockefeller Researchers Produce 3-D Picture of DNA-reading Molecular Machine

Researchers at The Rockefeller University have determined the first three-dimensional structure of the cellular RNA polymerase (RNAP), a molecular machine that activates individual genes by transcribing, or reading out, the instructions encoded in their DNA. The structure, published in the Sept. 17 issue of the journal Cell, provides scientists with a model for understanding the RNAPs of higher organisms, including humans. More »

Researchers Propose New Theory to Explain How Visual Pigments are “Tuned”

Scientists from the Howard Hughes Medical Institute (HHMI) at The Rockefeller University and from the University of California-Berkeley have proposed a new theory on how the human eye perceives colors. Using techniques of molecular biology and spectroscopy, the research, reported in the August issue of Trends in Biochemical Sciences, changes the way scientists have thought about color vision for nearly 20 years.

Rockefeller Scientists Discover a Surprising New Cancer Gene

Scientists at The Rockefeller University have found, for the first time, that the persistent activation of a protein called Stat3 can, by itself, cause normal cells to behave like cancer cells. The research, reported in the August 6 issue of Cell, provides both a scientific surprise and a promising new target in the fight against cancer. Scientists already knew that Stat3 was often activated in various human cancer types, including lymphomas, leukemias, breast cancer and a high percentage of head and neck cancers, but until now no one knew whether persistent Stat3 activation could contribute directly to the development of tumors.

Rockefeller Researchers Inject Cells, Boost Immune System in Humans

A single injection of specialized immune system cells­removed from the bloodstream and exposed to a foreign substance­can trigger a potent immune response in humans that lasts for months, Rockefeller University researchers report. The experiment provides the first conclusive evidence that one dose of these cells, called dendritic cells, can prompt a strong immune response, and it suggests new ways of improving vaccines and protecting against cancer.
