A Fern’s ‘Zombie’ Leaves Sprout Unusual Roots

In the rainforests of western Panama, the plant biologist Jim Dalling stumbled upon some tree ferns with six-foot-long leaves that bent to the ground as they were dying, encircling the plant like a skirt.“I was trying to move these things out of the way and then in the process, I realized these were rooted into the ground,” Dr. Dalling said. A professor and forest ecologist at the University of Illinois, he had been searching for a completely unrelated plant.The fern’s leaf remnants were brown and withered — dead, by all appearances (though still attached at their base to the tree fern’s trunk). How could lifeless plant matter be endowed with roots? he wondered.“I couldn’t really believe what I was seeing,” Dr. Dalling said.Further study revealed that this tree fern, known as Cyathea rojas...

Severe Frostbite Gets a Treatment That May Prevent Amputation

The first time Dr. Peter Hackett saw a patient with frostbite, the man died from his wounds. It was in Chicago in 1971, and the man had gotten drunk and passed out in the snow, his fingers so frozen that gangrene eventually set in.Dr. Hackett later worked at Mount Everest Basecamp, on Denali, Alaska, and now in Colorado, becoming expert in treating cold-weather injury. The experience was often the same: There was not much to do about frostbite, except rewarm the patient, give aspirin, amputate in severe cases and, more often, wait and accept that six months later the patient’s body might “auto-amputate” by naturally shedding a dead finger or toe.His mentor in Anchorage used to say, “Frostbite January, Amputation July,” remembered Dr. Hackett, clinical professor at the Altitude Research Cen...

Dani Alves – from 43 trophies to four years in prison

Dani Alves, who was this morning sentenced to four and a half years in prison in Spain after being found guilty of sexual assault, was, until very recently, one of global football’s golden boys.An exuberant, technical right-back, he was a major part of the Barcelona team that set new standards in the European game between 2008 and 2016. He played 126 times for Brazil and won 43 titles across his 22-year playing career — an astonishing number that makes him the second-most decorated footballer in history. Only Lionel Messi, his former team-mate at the Camp Nou, has more trophies to his name.That success, coupled with a relentlessly upbeat public persona, made Alves a hugely — almost universally — popular figure. It goes some way to explaining why his hearing, which took place over three day...

Instagram’s Uneasy Rise as a News Site

On a recent Wednesday in Brooklyn’s Dumbo neighborhood, Mosheh Oinounou, a former producer for CBS, Bloomberg News and Fox News, swiped through Instagram. He had started his morning reading major newspapers and more than a dozen newsletters. Then he spent much of the day turning many of the articles into posts on his Instagram account, under the handle Mo News.A Wall Street Journal story on aging Americans was relayed through a picture of a cake declaring, “Record Number of Americans Will Turn 65 This Year: Wealthy, Active, And Single.” At times, Mr. Oinounou, an affable 41-year-old, has also appeared on camera with the co-host of his daily news podcast to explain the significance of how Republican presidential candidates were polling and why President Biden was a write-in candidate in New...

Berkshire Hathaway Reports Profit of $97 Billion Last Year, a Record

Berkshire Hathaway, the conglomerate run for decades by Warren E. Buffett, recorded its highest-ever annual profit last year.

U.S. Imposes Major New Sanctions on Russia, Targeting Finance and Defense

The United States on Friday unleashed its most extensive package of sanctions on Russia since the invasion of Ukraine two years ago, targeting Russia’s financial sector and military-industrial complex in a broad effort to degrade the Kremlin’s war machine.The sweeping sanctions come as the war enters its third year, and exactly one week after the death of the opposition leader Aleksei A. Navalny, for which the Biden administration blames President Vladimir V. Putin of Russia. With Congress struggling to reach an agreement on providing more aid to Ukraine, the United States has become increasingly reliant on financial tools to slow Russia’s ability to restock its military supplies and to put pressure on its economy.Announcing the sanctions on Friday, President Biden reiterated his calls on ...

The fearless mindset of the Warriors’ Brandin Podziemski: ‘He’s got a delusion to him’

SAN FRANCISCO — Nearly a year ago on the dot, Mike Dunleavy, the Golden State Warriors’ future general manager, and Kent Lacob, an ascending front office personnel voice, hopped in a car and made the quick 50 mile trip south to Santa Clara’s campus.They were primarily there to see Maxwell Lewis, the possible lottery pick out of Pepperdine. Lewis played fine. He’d eventually get selected 40th in the 2023 NBA Draft. But he wasn’t the best player on the floor. Brandin Podziemski, a 6-foot-4 guard who was only beginning to creep onto the draft radar, made every significant play to lead Santa Clara to victory. His 23 points mattered. But it was the 18 rebounds that had Dunleavy’s and Lacob’s antennas up.“Mike and I walked out of the game like, ‘Um, that guy might be a first-round pick,'” Lacob ...

2 Years Into Russia-Ukraine War, U.S. Campaign to Isolate Putin Shows Limits

The Biden administration and European allies call President Vladimir V. Putin of Russia a tyrant and a war criminal. But he enjoys a standing invitation to the halls of power in Brazil.The president of Brazil says that Ukraine and Russia are both to blame for the war that began with the Russian military’s invasion. And his nation’s purchases of Russian energy and fertilizer have soared, pumping billions of dollars into the Russian economy.The views of the president, Luiz Inácio Lula da Silva, encapsulate the global bind in which the United States and Ukraine find themselves as the war enters its third year.When Russia launched its full-scale invasion of Ukraine on Feb. 24, 2022, the Biden administration activated a diplomatic offensive that was as important as its scramble to ship weapons ...
