Care, ‘magic’ help DC’s cherry blossom trees defy age


Peak bloom has arrived for the hundreds of Japanese cherry blossom timber on the Nationwide Mall in Washington, and the world is awash in magnificent pink and white.

Predicting the timing of peak bloom — outlined as when 70% of the blossoms have opened — has been getting more durable. Within the Nineteen Twenties, the common peak bloom was April 5. That moved as much as March 31 in recent times, and the 2023 peak arrived but per week earlier, based on the Nationwide Park Service on Thursday.

“I’m feeling like that is going to be the development” resulting from local weather change, stated Matthew Morrison, the park service’s city forester charged with overseeing the timber’ care.

The annual Nationwide Cherry Blossom Pageant, which runs by way of April 16, celebrates Japan’s 1912 reward of three,020 cherry timber to town of Washington.

Two of these timber have been planted by First Woman Helen Herron Taft and Viscountess Chinda, spouse of the Japanese Ambassador to america, with only a few onlookers current. That small gathering grew to become the origin of the pageant, which formally launched 23 years later, in 1934.

The common lifespan of a Japanese cherry tree falls roughly between 30 and 40 years, relying on selection, but the 2 timber planted by Taft and Chinda and a handful of different timber are nonetheless standing 111 years later.

“That defies science,” stated Morrison, who attributes the anomaly to “a bit little bit of magic tied to this excellent reward,” and the attentive, year-round care his staff offers.

Most of the 3,700 timber blooming on the 146-acre park right now are offspring of the originals, cultivated from clippings, Morrison stated. Others are repeatedly donated by the Casey Timber philanthropic group of Washington.

Morrison oversees a staff of simply three arborists charged with caring for the cherry timber, and retains a “private well being document” for every.

The arborists, armed with climbing gear, ladders and chippers, go to every tree to supply pruning and different care. They document their findings in a database.

Three years in the past, Morrison launched the observe of mulching the timber with “copious quantities of wooden chips” to create probably the most useful rising situations attainable. Because the chips decompose, he stated, they launch useful fungi and micro organism that join the timber’ root programs and “permit them to speak with each other and transport vitamins to one another, so now they operate as one super-organism.”

The wooden chips additionally function a bodily barrier between the garden and the timber, eliminating the mower and string-trimmer accidents which have plagued their decrease trunks for years.

Morrison recommends the identical observe for owners rising timber in their very own yards. When wooden chips are utilized over the basis zones, he stated, “you may just about flip your again on the tree,” including that “it will by no means want any fertilizer, amendments” or supplemental water.

“Even on the most well liked days of summer time when it hasn’t rained, I dig down within the wooden chips and discover moisture,” he stated.

For finest outcomes, Morrison advises including 6 inches of contemporary wooden chips round timber. “That 6 inches will compress to 3½ or 4 inches, and that’s a great stage to keep up,” he stated, including that the chips will smother grass and weeds so might be utilized proper over them.

Extra suggestions from Morrison:

— Maintain wooden chips at the least 3-4 inches away from tree trunks. Ideally, prolong them as far over the soil because the branches attain overhead, however, if essential, a smaller software might be made on smaller properties to keep away from mulching the whole yard.

— If grass grows by way of the wooden chips, use a steel rake to fluff them up or cowl the breakthrough development with extra chips.

— Lastly, be taught correct pruning methods, and prune away useless or diseased wooden each winter whereas the tree is dormant.

Morrison additionally recommends the Yoshino cultivar (that of many of the Nationwide Mall’s cherry blossom timber) to owners.

“It’s the most effective growers and one of the best to flower,” he stated. “Kwanzan cherry additionally is an effective grower and will get a bit greater than Yoshino.”

Earlier than choosing a tree to develop at residence, nevertheless, Morrison recommends discovering your native plant hardiness zone and researching which varieties will develop finest in your area.

As for the Nationwide Cherry Blossom Pageant, it spans 5 weekends and features a roster of occasions all through Washington and its suburbs, together with a Japanese avenue pageant, 5K and 10-mile runs, fireworks, meals gala’s and extra. For those who can’t make it, peep the timber reside by way of the Belief for the Nationwide Mall’s Bloom Cam.

Near miss on DC airport runway spurs FAA investigation


The Federal Aviation Administration (FAA) said it will investigate a near miss on the runway of the Ronald Reagan Washington National Airport outside Washington, D.C., Thursday morning, in which one plane nearly crossed into a runway as another plane was taking off.

According to an emailed statement from the FAA, an air traffic controller instructed a Southwest flight to cross one of the runways while a JetBlue flight was “starting its takeoff roll on the same runway.”

The incident happened Thursday around 7:41 a.m. local time. The near-miss happened between Southwest Flight 2937 and JetBlue Flight 1554, the FAA said.

Audio posted on YouTube shows air traffic controllers telling the planes to stop. The video, posted by VASAviation, said the Southwest flight was about 65 feet away from entering the runway and about 300 feet from the JetBlue plane, NBC News first reported.

The near collision comes after many flight-related incidents have occurred in the last several months, prompting the FAA to investigate.

In mid-January, the FAA said it was investigating a ground collision at Chicago’s O’Hare International Airport. Transportation officials and police have launched investigations into the communication between air traffic control and two planes after a fiery collision left five people dead in Japan in early January.

An investigative report by The New York Times published last August found that after reviewing FAA safety reports, there was an alarming pattern of safety lapses and near-misses in the skies and on runways in the United States. While no major crashes have occurred, the Times noted that the potentially dangerous incidents are happening more frequently than previously thought.

Hartzell in D.C. Seeks Congressional Support of Public AI Research and Workforce Initiatives


WASHINGTON, D.C. — With society at the forefront of an AI revolution, University of Texas at Austin President Jay Hartzell met with members of Texas’ congressional delegation, seeking support for the University’s artificial intelligence initiatives to dramatically expand the AI workforce and conduct critical research. Hartzell’s first trip to Capitol Hill as president underscored the significance and breadth of UT’s AI expertise and its importance to the future of the U.S. economy, national security and defense.

“We have the largest GPU cluster in all of academia. We are home to the National Science Foundation’s Institute for Machine Learning. And we are the headquarters of the Army Futures Command, which works closely with Texas Robotics and other disciplines,” Hartzell said during a reception at the Capitol on Tuesday night. “One challenge we have is the escalating cost of competing with the private sector. It is important that our country invests in public sector AI, and I am grateful to have support of key members of our Texas delegation, who hold seats on some of the most powerful committees in Washington.”

AI initiatives in public research universities such as UT are more often open and act as an enabler for the public good than those in the private sector. Yet, top AI talent has increasingly migrated to the higher-paying private sector. A 2023 survey published in Science.org found that nearly 70% of people with Ph.D.s in AI go to work in the private sector, compared with 21% two decades ago.

“UT has emerged as a leader in AI workforce development and research, and both of these are critical to America’s national security and defense,” said U.S. Rep. Henry Cuellar, D-Laredo, a member of the House Appropriations Committee and the Appropriations Defense Subcommittee. “I look forward to working with President Hartzell to continue building UT Austin’s research capacity and ensuring the next generation of researchers and scientists are from Texas.”

In 2023, UT launched a Master of Science in Artificial Intelligence (MSAI), the first large-scale degree program of its kind and the only master’s degree program in AI from a top-ranked institution. Combined with UT’s existing deep portfolio of AI degrees and programming, the University now has the ability to contribute to America’s AI workforce at an unrivaled capacity.

UT’s AI applications across defense and national security range from robots in conventional warfare to cybersecurity and cyberwarfare. The University is working with the Army Futures Command for rapid adoption and integration of AI systems and robotics for autonomous vehicles in a combat environment that could perform tasks such as search and rescue, mine-clearing operations, firefighting, and surveillance and reconnaissance.

UT’s Strauss Center for International Security and Law is conducting partially classified research on rules of engagement for AI-powered military systems and is advising the Office of the Director of National Intelligence (ODNI) on AI issues, including President Joe Biden’s executive order on the safe, secure and trustworthy development and use of AI.

“The University of Texas is leading the nation in AI research. It is critical to keep on pace with these developing technologies,” said U.S. Rep. Tony Gonzales, R-San Antonio, a member of the House Appropriations and Homeland Security committees. “I look forward to working alongside my colleagues in Congress and President Hartzell on this important initiative.”

Hartzell’s message was bolstered by University advertising in two prominent Washington Metro stations, dubbed “Metro Station Domination,” promoting UT as “the epicenter of AI excellence.” UT is uniquely positioned to lead across the spectrum of AI applications that align with the University’s top academic and research strengths. Hartzell has declared 2024 as the “year of AI” at UT.
