☆ Opinion | Is It Too Late to Save the Southern Grasslands?

I just assumed that Nashville was part of the great temperate deciduous forests that once covered much of the eastern half of the United States. When I went looking for the once-endangered Tennessee coneflower in 2019, I found them in a rocky glade surrounded by grasslands blooming with wildflowers. And if there are grasslands here now, surely there must have been grasslands here in the past. Today nearly all those Southern prairies — along with nearly all the other types of Southern grassland ecosystems, and nearly all the plants and animals they supported — are gone. In a study published in 2021, a team of scientists including Dr. Estes identified 118 major types of grassland ecosystems in the South.

A Fossil Mystery, Solved by a SpinEssexella fossils date back to the Carboniferous period, when northern parts of Illinois hovered just above the equator. Essexella fossils are composed of two structures — a textured, barrel-shaped region and a smooth bulb. “It looked like the bottom of an anemone,” Dr. Plotnick said. Dr. Plotnick, Dr. Hagadorn and their team redescribed Essexella as an ancient anemone last year in the journal Papers in Palaeontology. Dr. Plotnick posits that these animals once lined the floor of the Mazon Creek estuary.

☆ Climate change is messing with time more than previously thought, scientists find

CNN —The impacts of human-caused climate change are so overwhelming they’re actually messing with time, according to new research. “This is a testament to the gravity of ongoing climate change,” said Surendra Adhikari, a geophysicist at NASA’s Jet Propulsion Laboratory, and a report author. If the world continues to pump out planet-heating pollution, “climate change could become the new dominant factor,” outpacing the moon’s role, he told CNN. They found the impact of climate change on day length has increased significantly. They found any influence from the molten core was outweighed by that of climate change.

Ancient relative of the great white sharkMost species of Ptychodus lived between 100 and 80 million years ago during the late Cretaceous period. Because shark skeletons are made of cartilage, they do not fossilize well, typically leaving archaeologists only teeth and few skeletal remains to find. Lamniformes also includes the modern species of megamouth, sand, goblin and basking sharks, among others. “The crushing teeth together with the gigantic size make Ptychodus a very unique shark,” Amadori said. … Modern durophagous sharks (that consume hard-shelled organisms) are demersal, feeding on or near the bottom.

CNN —A unique plant has become the first species in the United States to be exterminated from the wild by the compounding effects of rising seas, scientists say. The Key Largo tree cactus still exists in parts of the Caribbean, including Cuba, Puerto Rico and the Bahamas, but the chances of it re-establishing naturally in the Florida Keys is basically “zero,” Gann said. The plant’s habitat was being swamped by saltwater from storms and high tides worsened by the rising sea. Sea levels around the Florida Keys have been rising by around an average 0.16 inches a year, or just over 8 inches since 1971, the researchers reported. Possley said more than 1-in-4 native plant species are critically threatened with regional extinction in South Florida.

The country’s Disaster and Emergency Management Authority is active but relatively new in its current form, having been consolidated as a single agency only in 2009. The practice of emergency management has generally originated from the first responder community and the civil defense era, primarily with a focus on consequence management. But as emergency management agencies have been designed, emergency management systems have been shaped by laws and agreements across government bureaucracies and partners in the private and nonprofit sectors with a narrower focus on managing consequences, focused more on logistics than sociology. But disaster management in practice is still fundamentally a numbers game. Strong emergency management agencies are also important.

It is the world’s largest reconstruction of a Bronze Age Magan boat, according to the team. The research project’s goals were to uncover ancient craftsmanship techniques, determine the connections between Bronze Age societies and better understand the role Abu Dhabi once played in Bronze Age trade. After passing five days of trials, the ship sailed toward Saadiyat Island off the coast of Abu Dhabi and the open sea on March 2 and 3. “Seeing the Magan Boat sail on the water for the first time actually took my breath away and brought tears to my eyes.”

CNN —Sex and gender are often conflated or equated in everyday conversations, and most American adults believe a person’s gender is determined by sex assigned at birth. But a new study of nearly 5,000 9- and 10-year-olds found that sex and gender map onto largely distinct parts of the brain. The researchers on the new study defined sex as what was assigned to the child at birth. They also hope to see how different cultures affect a person’s gender and their brain development. The study did not look at whether sex or gender were congruent or incongruent in any study participant.

Brazil is still weeks away from its traditional fire season, but hundreds of blazes, fanned by searing temperatures, are already laying waste to the Pantanal, the world’s largest tropical wetlands, and to parts of the Amazon rainforest. Scientists say the burning of such vast swaths of land may represent a new normal under rising global temperatures and uneven rain, making efforts to save some of the world’s most important ecosystems much harder. There were more wildfires in Brazil’s share of the Pantanal, an enormous trove of biodiversity stretching across three countries, between January and June of this year than during the same period in any other year, according to the National Institute for Space Research, which has been tracking fires in Brazil since 1998. The highest number of fires in at least two decades was also recorded in the Amazon and in the Cerrado savanna, a patchwork of shrubs, grasslands and gnarled trees encompassing 1.2 million square miles in Brazil’s central and northeastern regions.

Cars that run on hydrogen emit zero carbon at the tailpipe, but 96% of the world’s hydrogen is still derived from fossil fuels like methane gas. That makes most hydrogen-powered cars much more polluting than battery electric vehicles, or EVs, and only marginally cleaner than traditional combustion engine cars. Toyota is supplying the Game’s official fleet, which includes 500 Mirai cars and 10 coaches that run on hydrogen, as well as 1,150 EVs, to ferry athletes around. It is also one a few major automakers betting on hydrogen-powered vehicles, as well. Hydrogen vehicles have so far failed to take off as a popular choice for consumers, and very little infrastructure to refuel with hydrogen exists.

They probed the sample with an innovative experimental technique that revealed the three-dimensional architecture of the mammoth’s genome. Hendrik Poinar, an evolutionary geneticist at McMaster University in Canada, was “floored” — the technique had successfully captured the original geometry of long stretches of DNA, a feat never before accomplished with an ancient DNA sample. “It’s absolutely beautiful,” said Dr. Poinar, who reviewed the paper for the journal. An organism’s full genome resides in cell nuclei, in long, unfragmented DNA strands called chromosomes. “To have the actual architectural structure of the genome, which suggests gene expression patterns, that’s a whole other level,” Dr. Poinar said.

The sun felt hotter than usual in Houston this week, as millions of sweltering residents emerged from the rapid thrashing of Hurricane Beryl to face a prolonged power outage — the largest ever seen by the city’s utility, according to the state’s lieutenant governor. The outages from the storm affected as many as 2.7 million customers across the state, mostly in and around Houston. Despite a promise by the utility, CenterPoint Energy, to restore power to one million customers by the end of the day on Wednesday, large swaths of the nation’s fourth-biggest city remained without power. The scale of the outages raised questions about whether enough had been done to prepare the city, just 50 miles from the Gulf Coast, for the kinds of storms that climate scientists predict will arrive with greater frequency. “For a Category 1 hurricane to result in over a million customer outages in its immediate aftermath demonstrates that there is plenty of need for the resiliency hardening investments,” said Wei Due, an energy expert with PA Consulting and a former senior analyst and engineer for Con Edison.
