Say WOW

Suborbital space tourism finally arrives | FCC prepares to run public C-band auction | The big four in the U.S. launch industry — United Launch Alliance, SpaceX, Blue Origin and Northrop Grumman — hope to be one of two providers that will receive five-year contracts later this year to launch national security payloads starting in 2022. | China’s launch rate stays high | The International Space Station is the largest ever crewed object in space.

Researchers improve efficiency of next-generation solar cell...

Perovskites are a leading candidate for eventually replacing silicon as the material of choice for solar panels. They offer the potential for low-cost, low-temperature manufacturing of ultrathin, lightweight flexible cells, but so far their efficiency at converting sunlight to electricity has lagged behind that of silicon and some other alternatives. Now, a new approach to the design of perovskite cells has pushed the material to match or exceed the efficiency of today’s typical silicon cell, which generally ranges from……

Loudoun Co. superintendent, school board irked by...

The number of COVID-19 cases in Loudoun County is currently too high to bring students back to school buildings more than two days per week, Interim Superintendent Scott Ziegler told the school board. Looking forward, Ziegler and School Board Member Jeff Morse both voiced frustration with the Centers for Disease Control and Prevention’s guidelines for safely returning students to classrooms, saying Virginia school systems would have to disregard CDC guidelines to bring more students back. Although coronavirus cases locally…

5 Fingers Observation Deck in Obertraun,...

Although Hallstatt is the first thing that pops up on maps when viewing the Obertraun in the Austrian Alps, there is much more to the area than a quaint little town. Visitors to the Dachstein Mountains will find a free observation deck that offers astonishing views. Named 5 Fingers due to the hand-shaped form of the platform, the observation deck reaches out over a 400-meter drop. Each finger allows visitors to view various perspectives of Hallstatt and Hallstättersee lake. Opened in October……

The Champion in London, England

Walking into this pub near the westerly end of Oxford Street, visitors may think that they have time-traveled back to the Victorian period. The bar is indeed from the late 1800s and features historic fixtures like a “snob screen,” a panel of etched glass that swivels, allowing the patrons to have an air of privacy between themselves and those working behind the bar. The Victorian-era apparatus in the Champion is one of only a handful in existence in the United……

Q&A: Ceasar McDowell on better public conversation

Last year leaders in Poughkeepsie, New York, started the Children’s Cabinet, an organization aimed at bolstering cradle-to-career services and support for the city’s kids. With a wide-ranging agenda, they wanted to figure out how to reach the community for input — and worked with Ceasar McDowell, professor of the practice of civic design and associate head of MIT’s Department of Urban Studies and Planning (DUSP). McDowell is an expert in designing public conversations and leads We Who Engage MIT,……

Data transfer system connects silicon chips with...

Researchers have developed a data transfer system that can transmit information 10 times faster than a USB. The new link pairs high-frequency silicon chips with a polymer cable as thin a strand of hair. The system may one day boost energy efficiency in data centers and lighten the loads of electronics-rich spacecraft. The research was presented at this month’s IEEE International Solid-State Circuits Conference. The lead author is Jack Holloway ’03, MNG ’04, who completed his PhD in MIT’s……

China’s Mars craft enters parking orbit before...

BEIJING (AP) — China says its Tianwen-1 spacecraft has entered a temporary parking orbit around Mars in anticipation of landing a rover on the red planet in the coming months. The China National Space Administration said the spacecraft executed a maneuver to adjust its orbit early Wednesday morning Beijing time and will remain in the new orbit for about the next three months before attempting to land. During that time, it will be mapping the surface of Mars and…

How an Arizonan Company Turns Cacti Into...

In mid-August, 17-year-old Lynette Alvarez and her aunt, Nellie Botello, put on matching camouflage snake guards and steel-toed boots for their work gathering prickly pear cactus fruit. Snake-season is year round in the Arizona desert, and there are baby rattlesnakes in the summer that may not make warning rattles yet. Along with a handful of pickers, they start as early as 4 a.m. to avoid the scorching afternoon heat. By 9 a.m., when they stop, the group will have……

Can the Mighty Bankhar Dogs of Mongolia...

On the Mongolian steppe, there are predators, there are prey, and there are the bankhar. These large, powerful dogs weigh up to 125 pounds, with shaggy, thick coats that give them a bear-like appearance. For 15,000 years, bankhar dogs have been the guardians of the steppe. In these grasslands, sheep and other livestock kept by traditional nomadic herders are under constant threat from wolves, eagles, and even snow leopards. For millennia, the bankhar safeguarded both animals and the family’s……

The Bowder Stone in Borrowdale, England

Located near the River Derwent is the quirkiest tourist attraction in the Lake District.  Standing around 29 feet (nine meters) high and 49 feet (15 meters) in diameter, there is some debate over whether this massive rock is a glacial erratic from Scotland or a huge piece of rock that fell from Bowder Crag above.  Borrowdale was once littered with rocks and was avoided by travelers due to the difficult terrain. However, in the early 1800s, this enormous boulder was……

George Stephenson Statue in Chesterfield, England

Situated right outside this train station is a life-sized bronze statue of steam railway innovator George Stephenson, often known as the “Father of the Railways.” Stephenson lived in Chesterfield at nearby Tapton Hall during the latter part of his life. At the time, he was working on the North Midland Railway between Derby and Leeds.  Commissioned as part of Chesterfield Borough Council’s Percent for Art Policy, the sculpture was paid for by developers in town. Stephen Hicklin was the……

The Tiny Building That Pays Tribute to...

If you’d driven along Pittsburgh’s Webster Avenue decades ago, you may have caught a glimpse of Black suffragist and civil rights activist Daisy Lampkin at her home. The red-brick building on the corner stretches three stories tall, with ornamental cornices and rows of windows. It was Lampkin’s house for four decades, when she wasn’t traveling for work with the NAACP. The building still stands today—and now, so does a miniature version of it. An eight-inch model of Lampkin’s residence……

Fight or flight? Why individuals react as...

Why do some people fight and others flee when confronting violence? “This question has been bothering me for quite some time,” says Aidan Milliff, a fifth-year doctoral student who entered political science to explore the strategic choices people make in perilous times. “We’ve learned a great deal how economic status, identity, and pressure from community shape decisions people make while under threat,” says Milliff. Early in his studies, he took particular interest in scholarship linking economic deprivation to engagement……

Tounj Bridge in Zdenac, Croatia

This impressive two-level bridge spanning the canyon of the Tounjčica is also historically important.  The first level of the bridge was inspired by Roman architecture. It was constructed in 1775 to honor the Austrian emperor and Croatian king Joseph II. In 1836, with the renovation of the road, a second level was designed with sculptures.  During World War II, the upper level was mostly destroyed and replaced with a temporary wooden structure between 1957-1973 when the bridge was finally……
