Differences between vowels and consonants are real
While working with colleagues in Rome, two Harvard researchers serendipitously met two women with intriguing speech deficits. As the result of a stroke, one patient could not reproduce the sounds of vowels properly. Another patient experienced the same trouble with consonants. After studying the two women, the Harvard team concluded that the difference between vowels…

Despite some progress, segregation persists in Boston area
A report, “Segregation in the Boston Metropolitan Area at the End of the 20th Century,” found that despite the progress that disadvantaged minorities have made in achieving homeownership outside of Boston, there is a danger that the benefits of such ownership may not accrue to them because of racial and ethnic segregation. In particular, the…

Closing in on the ‘theory of everything’
A single theory describing nature’s four forces, called the “Theory of Everything,” has been the Holy Grail for physicists and other scientists seeking the universe’s deepest mysteries. Physicist Juan Maldacena has devised a way to explain gravity using a theory that also explains the other three basic forces of nature. And in this day of…

Researchers switch cancer off and on in mice
An antibiotic added to the drinking water of mice stops the progress of leukemia. Harvard researcher Claudia Huettner cannot do the same thing in humans, unfortunately, but through such experiments Huettner and her colleagues are gaining an understanding of how human leukemias arise. The new knowledge they have gained is providing them with a means…

High stakes tests in Texas threaten disadvantaged students
Texas is frequently cited as a national leader in efforts to raise academic performance and hold schools accountable for student performance. At the center of these efforts is the statewide standardized test, the Texas Assessment of Academic Skills (TAAS), administered to public school children in grades 3 to 10. Students must achieve a minimum score…

Women priests, vegetarianism – early Christian manuscript holds surprises
In the early days of Christianity, when the first Christians were spreading the faith, diversity of belief was the norm rather than the exception. An early manuscript uncovered by a Harvard professor, for example, describes a community of celibate vegetarians in which both women and men functioned as priests. “The usual view is that in…

Study says children with cancer often suffer needlessly
“Since caregivers are very committed to curing their patients, it may be difficult for them to recognize when to incorporate palliative care into treatments, even when there’s little hope of cure,” notes Joanne Wolfe, an instructor at Harvard Medical School and lead author of a report, published in The New England Journal of Medicine, that…

New detector may open new window on the universe
A new receiver is capable of detecting and amplifying very-high- frequency signals with very fine frequency resolution, so it can detect the spectral lines, or chemical fingerprints, of interstellar molecules that emit radio signals at terahertz frequencies — the highest frequencies ever achieved with any radio receiver. The unique detector of astronomical radiation, developed at…

Little giants create a big cosmic controversy
A new measuring technique used to determine the distances to a class of stars called “Red Clumps” in the Large Magellanic Cloud produced a much smaller distance than that found by other popular methods of measurement. The smaller distance means that the universe may be expanding faster than previously thought — a finding which has…

Streamers of gas feed beast at center of our galaxy
Astronomers have long known that a supermassive black hole, more than 2 million times more massive than our Sun, lies at the center of the Milky Way Galaxy some 27,000 light-years from Earth. A point-like source of radio emission called Sagittarius A* (pronounced “A-star”) marks the location of this black hole. Now researchers Robin S.…

Study finds biotech workers ‘thrive’ on instability
Marked by job insecurity, dependence on changing technology, and uncertain financing, the biotechnology industry is viewed by researchers as one of the best examples of the workplace of the future. A study by the Radcliffe Public Policy Center (RPPC) released in December 1999 found that biotech workers were actually thriving in this highly unstable environment.…

State-of-the-art health guide created
Harvard Medical School believes it has a cure for problems associated with finding accurate, up-to-date medical information: a comprehensive (1,288 pages), $40 medical guide tied to a Web site that will update the book weekly. Published by Simon and Schuster in October 1999, it’s the first family health guide that will never go out of…

‘Take two aspirin and call me manana’
Harvard Medical School is attempting to bridge the language barriers that sometimes arise in medical settings. A set of three medical phrasebooks was first offered in 1999 in three different languages: Communicating with the Patient during Urgent Care, Communicating with the Patient on Work Rounds, and Communicating with the Patient during Review of Systems. All…

Black silicon: A new way to trap light
Eric Mazur, Harvard College Professor and Gordon McKay Professor of Applied Physics, and his students were studying what kinds of new chemistry can occur when lasers shine on metals, like platinum. One day, they decided to put a chip of gray silicon into a vacuum chamber, add some halogen gas, and scan it with ultrashort,…

Industrial disasters sparked field of environmental health
Two large, unnatural disasters helped to create the impetus for the field of environmental health to grow in scope. But before there was a U.S. Environmental Protection Agency and before the National Institutes of Health (NIH) included environmental health, there was the Kresge Center for Environmental Health at Harvard’s School of Public Health. Beginning in…

21 moons ‘swarm’ planet Uranus
In 1999 three new moons were discovered orbiting Uranus, a great gasball of a planet about 2 billion miles from Earth. The discovery raised the number of Uranian moons to 21, the most, as far as is known, in the skies of any planet. Researchers believe the moons were “captured” billions of years ago. “We…

New electronic tools reveal forgotten China
German-born photographer Hedda Hammer Morrison (1908-1991) could often be seen bicycling through Peking with a Rolleiflex camera around her neck, capturing her times through her lens as both participant and observer. A simple way of life was rapidly changing in the 1930s and ’40s behind the walls of China’s Forbidden City. Morrison’s photographs of Peking…

Exploring big and small possibilities of the information revolution
” ‘System-on-a-chip’ is the new buzzword today,” said Professor Woodward Yang in 1999. “It’s really not that far away.” As Yang sees it, the computer revolution is really just beginning. Systems are poised to become smaller, more portable, and found everywhere from traditional desktops to cell phones and pagers. Yang in 1999 said researchers are…

Student-designed lamp brightens Harvard dorms
Halogen lamps became increasingly popular through the ’90s. Their high-wattage bulbs gave off a clear, pleasant light and — at $15 to $25 — even a student could afford them. Unfortunately, the lamps also gobbled electricity and their bulbs burned hot enough to be blamed for several fires and two fatalities. As part of her…
