New study reveals wildfire smoke linked to staggering 24,100 deaths annually in the U.S.

Image
By DORANY PINEDA, Associated Press Chronic exposure to pollution from wildfires has been linked to tens of thousands of deaths annually in the United States, according to a new study. The paper, published Wednesday in the journal Science Advances, found that from 2006 to 2020, long-term exposure to tiny particulates from wildfire smoke contributed to an average of 24,100 deaths a year in the lower 48 states. RELATED: How a new system of drones and low-cost sensors can protect communities from air pollution “Our message is: Wildfire smoke is very dangerous. It is an increasing threat to human health,” said Yaguang Wei, a study author and assistant professor in the department of environmental medicine at Icahn School of Medicine at Mount Sinai. Other scientists who have studied the death toll from wildfire smoke were not surprised by the findings. “The estimates they’re coming up with are reasonable,” said Michael Jerrett, professor of environmental health science at the Universit...

NASA delays astronauts’ lunar trip until March after hydrogen leaks mar fueling test

By MARCIA DUNN, Associated Press CAPE CANAVERAL, Fla. (AP) — NASA’s long-awaited moonshot with astronauts is off until at least March because of hydrogen fuel leaks that marred the dress rehearsal of its giant new rocket.

Opinion: New federal dietary guidelines mark troubling retreat on alcohol

The Trump administration’s recently updated Dietary Guidelines for Americans mark a troubling retreat from the best available science about alcohol consumption. At a time when alcohol-related fatalities have increased 30% over the last decade — now claiming approximately 178,000 American lives annually — the federal government has missed a critical opportunity to safeguard the nation’s health. Alcohol hasn’t changed, but our understanding of its risks has evolved considerably. Decades of research and federal advisory findings indicate that no amount of alcohol is truly safe for health, yet the updated dietary guidelines fail to clearly warn the public or provide sufficient information for people to make informed choices. Some omissions are stark. For example, the updated dietary guidelines fail to address the well-established link between alcohol and cancer risk. Alcohol is a known carcinogen linked to several types of cancer, including breast, colon and liver cancer. Related ...

US life expectancy hit an all-time high in 2024, CDC says

By MIKE STOBBE, Associated Press NEW YORK — U.S. life expectancy rose to 79 years in 2024 — the highest mark in American history. It’s the result of not only the dissipation of the COVID-19 pandemic, but also waning death rates from all the nation’s top killers, including heart disease, cancer and drug overdoses. What’s more, preliminary statistics suggest a continued improvement in 2025. “It’s pretty much good news all the way around,” said Robert Anderson, of the National Center for Health Statistics at the Centers for Disease Control and Prevention, which released the 2024 data on Thursday.

Is the East Bay earthquake swarm finally over?

The earthquake swarm that has shaken San Ramon for more than two months appears to be over, scientists said Monday. But when it comes to earthquake swarms, nothing is set in stone. Since Nov. 9 there have been 91 earthquakes of magnitude 2.0 and above — the largest being a 4.0 on Dec. 19 — in the East Bay community. But no quake of that size has happened since Jan. 10, when a 2.3 and 2.0 both occurred there. “There’s been a gap for about two weeks,” said Sarah Minson, a research geophysicist with the U.S. Geological Survey’s Earthquake Science Center at Moffett Field. “It looks like the swarm may be done.” The challenge, she noted, is that scientists are still learning about earthquake swarms, which are collections of dozens or even hundreds of small, usually harmless quakes. And they don’t have strict parameters for when swarms start or conclude. “There isn’t a good way to officially define when swarms begin and end,” Minson said. “If there was more activity now we would probably ...

Stunning California snake endangered since the 1960s prepares to make a comeback

In an unassuming building at the San Francisco Zoo, 115 brilliantly colored baby snakes are being fattened up on a diet of worms. These are endangered San Francisco garter snakes and during a visit in early December, they were small enough to curl up in a ball in the palm of your hand. Each has a red-orange head, a turquoise belly, and vivid red and blue-yellow stripes. Jamie McNellis, a Conservation Specialist at the San Francisco Zoo, holds four-month-old garter snakes kept in enclosures at the San Francisco Zoo in San Francisco, Calif., on Thursday, Dec. 4, 2025. (Ray Chavez/Bay Area News Group)  “They are considered by many people to be the most beautiful snake in the world,” said Jamie McNellis, a conservation specialist and lead snake care expert at the zoo. Listed as endangered since 1967, San Francisco garter snakes are found only on the Peninsula and in northern Santa Cruz County. They have been in trouble for decades, threatened by urban development, which has fragme...
