Writing in the July 28, 2005 edition of the New England Journal of Medicine, John Halamka, M.D., chief information officer at BIDMC and Harvard Medical School and an emergency room…
In the early 1970s Folkman refined his theory that tumors have the capability to grow their own blood vessels, thereby obtaining the nourishment they need to keep growing in a body. Folkman never quit thinking about why this happens and how he might use that information to treat cancer patients.
“Based on this study’s results, showing the importance of personal contact with violence, the best model for violence may be that of a socially infectious disease,” says Felton Earls, MD,…
Astronomer Scott Gaudi of the Harvard-Smithsonian Center for Astrophysics believes that microlensing has the potential for wide use in the future: “With improving technologies and techniques, the first Earth-sized planet…
Cullen Blake, a graduate student at the Harvard-Smithsonian Center for Astrophysics and lead author on the paper, said that the simultaneous observation of infrared light with a gamma-ray burst was…
The study’s lead author, Megan Gerber, a practicing physician at Cambridge Health Alliance and instructor of medicine at Harvard Medical School, notes: “Our study hopes to raise physician awareness of…
Matthew DePetro ’05 earned top honors for his senior design project, “Wireless Cable Television.” The first-prize entry “untethers” standard cable TV and even eliminates the need for a wall outlet.…
Using a new computer model of galaxy formation, researchers have shown that growing black holes release a blast of energy that fundamentally regulates galaxy evolution and black hole growth itself.…
The study singled out substantial weight gain while running, long race duration, and a lower body mass index as the primary risk factors for hyponatremia in runners. Researchers suggest that…
In trying to solve the riddle of Sedna’s “missing moon,” scientists Scott Gaudi, Krzysztof (Kris) Stanek and colleagues at the Harvard-Smithsonian Center for Astrophysics took measurements that have cleared up…
Ramesh Shivdasani, M.D., Ph.D., of Dana-Farber, said the finding “opens a window that could help us eventually interfere with these pathways when they become abnormal. It should give us a…
When a 7-million-year-old skull was first found, Daniel Lieberman, a professor of anthropology at Harvard, called it “one of the greatest discoveries of the past 100 years.” After studying new…
“A snail crawling on Mars would appear to be moving across the surface more than 100 times faster than the motion we measured for this galaxy,” said Mark Reid of…
Gefitinib acts on the receptor for the epidermal growth factor protein (EGFR) to halt the spread of cancer cells by fitting into the activating pocket of the protein, blocking the…
Researchers have uncovered strong evidence that the ancient Chinese used diamonds to grind and polish ceremonial stone burial axes as long as 6,000 years ago – and incredibly, did so…
A survey of 18,000 college students enrolled in introductory biology, chemistry, and physics has found little evidence that high school Advanced Placement (AP) courses significantly boost college performance in the…
Just knowing that a protein is expressed in a cell does not reveal what it is up to; increasingly, the chemical modifications it undergoes are the key to understanding its…
Common wisdom among astronomers holds that most star systems in the Milky Way are multiple, consisting of two or more stars in orbit around each other. Common wisdom is wrong.
A study conducted by Robert J. Sampson of Harvard University and Jeffrey D. Morenoff and Stephen Raudenbush of the University of Michigan shows that the longstanding gap in the racial…
Non-coding regions of the genome – those that don’t code for proteins – are now known to include important elements that regulate gene activity. Among those elements are microRNAs, tiny,…
A safety group at Harvard University has looked into the behavior of those in training in hospitals and found that overworked interns made 36 percent more serious medical errors and…
Astronomers announced Jan. 12, 2006 that they have found the first sample of intermediate-mass black holes in active galaxies – a discovery that will help in understanding the early universe.…
The roiling cores of many active galaxies are difficult to see in detail because of surrounding gas and interstellar dust. Smithsonian astronomers announced Jan. 12, 2006, however, a first-time measurement…
Astronomers announced Jan. 11, 2006, that they have found the next Orion Nebula. Known as W3, this glowing gas cloud in the constellation Cassiopeia has just begun to shine with…
To peer into the galactic center of our own Milky Way galaxy, astronomers Silas Laycock and Josh Grindlay used the unique capabilities of the 6.5-meter-diameter Magellan Telescope in Chile. By…
Observations by two astronomers confirm one important theory about how a black hole’s extreme gravity can stretch light. The data also paint an intriguing image of how a spinning black…
By a score of 135 to zero, scientists using NASA’s Rossi X-ray Timing Explorer have compared suspected neutron stars and black holes and found that the black holes behaved as…
Helix Nebula (NGC 7293) is a challenging stargazing target for amateur astronomers. It is one of the closest planetary nebulas – a type of nebula formed from gas ejected by…
