The earliest known image of an Egyptian ruler wearing the “White Crown” associated with Egyptian dynastic power has been brought to light by an international team of archaeologists led by Egyptologists from Yale University.

Carved around 3200 BCE, this unique record of a royal celebration at the dawn of the Egyptian dynastic period was found at a site discovered almost a half-century ago by Egyptologist Labib Habachi at Nag el-Hamdulab, on the West Bank of the Nile to the north of Aswan. (more…)

New Zealand Mountain Named in Honor of Yale Astronomer

Acclaimed by her peers in the United States as “possibly the greatest woman scientist of the 20th century” and known in her native New Zealand as a “world leader in modern cosmology and one of the most creative and significant theoreticians in modern astronomy,” the late Yale astronomer Beatrice Tinsley has certainly earned a place in the annals of history.

Now she’s earned a place in the World Atlas as well. (more…)

ANN ARBOR, Mich.— Using the deepest X-ray image ever taken, a University of Michigan astronomer and her colleagues have found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA’s Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

By pointing Chandra at a patch of sky for over six weeks, astronomers obtained what is known as the Chandra Deep Field South (CDFS). When combined with very deep optical and infrared images from NASA’s Hubble Space Telescope, the new Chandra data allowed astronomers to search for black holes in 200 distant galaxies, from when the universe was between about 800 million and 950 million years old.

With summer upon us, Yale Medical Group physicians have an urgent warning: Be sun smart. Practicing good sun protection, including the use of sunscreen, could save your life, they say.

“You don’t want to go crawl under a rock or hide in the basement,” says dermatologist Dr. David Leffell, CEO of Yale Medical Group and a member of Yale Cancer Center. “You want to be active and that usually is best done outdoors — simply use moderation and common sense.” (more…)

In Summer Session, Students can Take a Yale Course From Afar

Students from around the world will have the opportunity to take a Yale course this summer even if they are unable to come to campus.

The University is embarking on an experimental pilot program to offer Yale Summer Session courses, all taught by noted Yale faculty members, through an online platform. The overall program involves four Yale Summer Session courses, with two of the four courses available for credit. The five-week, for-credit courses are open to current college students and others beyond college. Students apply for admission to the courses as they would for any in-resident Yale Summer Session course. (more…)

Yale Researchers Identify Four Key Weapons in Immune System’s Arsenal

Yale University researchers have identified four unique host defense proteins among thousands that seem to play a crucial role in mobilizing the immune system’s response to bacterial infections, they report in the May 6 issue of the journal Science.

The findings suggest it may be possible to find new ways to assist immune-compromised patients to fight off a variety of pathogens, the authors say.

“We can start to think about how to mimic these chemical processes and deliver them in drug form,” said John D. MacMicking, associate professor of microbial pathogenesis at Yale School of Medicine and senior author the study. (more…)

Bringing more Power to African Farmers Through Simple Technology

In a room in the basement of Hillhouse Avenue, 18 Yale students have spent the past 12 weeks transforming gears, wing nuts and sprockets into energy solutions for farmers working thousands of miles away in sub-Saharan Africa.

The class, called “Appropriate Technology for the Developing World,” was inspired by a trip that faculty member John Morrell took to Africa in 2009 with an international team of scientists, after learning that African farmers often earn just $1 to $2 a day. (more…)

Scientists Build the World’s First Anti-laser

More than 50 years after the invention of the laser, scientists at Yale University have built the world’s first anti-laser, in which incoming beams of light interfere with one another in such a way as to perfectly cancel each other out. The discovery could pave the way for a number of novel technologies with applications in everything from optical computing to radiology.

Conventional lasers, which were first invented in 1960, use a so-called “gain medium,” usually a semiconductor like gallium arsenide, to produce a focused beam of coherent light-light waves with the same frequency and amplitude that are in step with one another. (more…)
