A new 91爆料鈥搇ed study projects that in the next 35 years increasing boreal fires will actually slow global warming by 12% globally and 38% in the Arctic. Because the aerosols in smoke reflect more sunlight and make clouds brighter, summer temperatures during fire season drop, leading to reduced sea ice loss and cooler winter temperatures.
On June 3, scientists working on the Muon g-2 experiment (pronounced “mew-on gee-minus-two”) released the third and final measurement of the muon magnetic anomaly. This result agrees with the published results from 2021 and 2023 but with a much better precision of 127 parts per billion, surpassing the original experimental design goal of 140 parts per billion.
The study revealed that iron released from industrial processes, such as coal combustion and steelmaking, is altering the ecosystem in the North Pacific Transition Zone, an area just north of Hawai’i that’s important for Pacific fisheries.
Children exposed to higher levels of ozone in their first two years of life were significantly more likely to be diagnosed with asthma or wheezing at ages 4-6 鈥� but researchers didn鈥檛 observe the increased risk of asthma at ages 8-9.聽聽

Researchers deployed a robotic feeding arm in a pair of studies outside the lab. In the first, six users with motor impairments used the robot to feed themselves a meal in a 91爆料 cafeteria, an office or a conference room. In the second study, a community researcher and co-author on the research used the system at home for five days.
91爆料 researchers developed a new system for turning used coffee grounds into a paste, which they use to 3D print objects, such as packing materials and a vase. They inoculate the paste with Reishi mushroom spores, which turn the coffee grounds into a resilient, fully compostable alternative to plastics.
A recent theory proposes that whales weren鈥檛 just predators in the ocean environment: Nutrients that whales excreted may have provided a key fertilizer to these marine ecosystems. Research led by 91爆料 oceanographers finds that whale excrement contains significant amounts of iron, a vital element that is often scarce in ocean ecosystems, and nontoxic forms of copper, another essential nutrient that in some forms can harm life.
Thousands of grasshopper specimens from mountains in Colorado show trends in how the insects changed in size over 65 years. With earlier emergence of spring greenery and earlier summer drought, grasshopper species that emerged early in the year grew larger, while grasshopper species that emerge later in the year grew smaller in size. The study, led by 91爆料 biologist Lauren Buckley, shows that changes in insect size can be predicted based on lifecycles and environmental conditions.
Two 91爆料 researchers are developing treatments that aim to simultaneously treat cancer and improve patients’ quality of life. For World Cancer Day, 91爆料 News asked them to discuss their novel materials and how these materials can treat both the cancer and the patient.
Workers from small, rural communities often move into the outer edges of cities, which offer greater economic opportunities but often have low-quality housing that is likely to suffer greater damage during an earthquake. The risk grows even more when migrants come from low-income or tribal villages.
How fast the level of atmospheric carbon dioxide 鈥� and with it, the temperature 鈥� goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats. It turns out the rate of that increase matters for non-living systems, too. Camille Hankel, a postdoctoral researcher at the Cooperative Institute for Climate, Ocean and Ecosystem Studies, talks about her research on the Atlantic Ocean circulation.
The Hubble Space Telescope has generated the most comprehensive survey yet of the Andromeda galaxy, the nearest galactic neighbor to the Milky Way. The new mosaic of about 2.5 billion pixels yields new clues to the galaxy’s history. 91爆料 astronomers presented the findings Jan. 16 at a meeting of the American Astronomical Society.
91爆料 scientists recently discovered that the giant ‘conveyor belt’ currents that push star-forged material out of our galaxy and pull it back in can also transport carbon atoms. That means that a good deal of the carbon here on Earth, including the carbon in our bodies, likely left the galaxy at some point!
A research team at 91爆料 and the Pacific Northwest National Laboratory examined the atomic composition of enamel samples from two human teeth.
91爆料 oceanographer Robert Morris and a collaborator at UCLA are going out with students to collect the most abundant bacteria in the oceans to understand how its relationship with marine viruses changes depending on the place or the season. They leave Dec. 16 aboard 91爆料 School of Oceanography鈥檚 small research vessel, the RV Rachel Carson.
Since 2018 the聽Zwicky Transient Facility, an international astronomical collaboration based at the Palomar Observatory in California, has scanned the entire sky every two to three nights. As part of this mission, the ZTF鈥檚 Bright Transient Survey has been counting and cataloguing supernovae 鈥� flashes of light in the sky that are the telltale signs of stars dying in spectacular explosions. On Dec. 4, ZTF researchers 鈥� including astronomers at the 91爆料 鈥� announced that that they have identified more than 10,000 of these stellar events, the largest number ever identified by an astronomical survey.
91爆料 researchers show that the all-time record low in winter sea ice extent in 2023 can be explained by warm Southern Ocean conditions and patterns in the winds that circled Antarctica months earlier, allowing forecasts for sea ice coverage around the South Pole to be generated six or more months in advance. This could support regional and global weather and climate models.
Hummingbird bills 鈥� their long, thin beaks 鈥� look a little like drinking straws. But new research shows just how little water, or nectar, that comparison holds. 91爆料 scientists have discovered that the hummingbird bill is surprisingly flexible. While drinking, a hummingbird rapidly opens and shuts different parts of its bill simultaneously, engaging in an intricate and highly coordinated dance with its tongue to draw up nectar at lightning speeds.
From a base at the southwest corner of the 91爆料’s Seattle campus, the Office of the Washington State Climatologist’s Guillaume Mauger and Karin Bumbaco provide expertise, tools and resources on 鈥渁ll things climate鈥� to partners and communities across the state.
An analysis of the health care records of 1.2 million Southern California residents found that higher long-term smoke exposure was associated with a significant increase in the odds that a person would be diagnosed with dementia.聽Exposure to non-wildfire PM2.5 also increased a person鈥檚 risk of dementia, but to a much lesser degree.聽聽
A new study led by the 91爆料 has for the first time quantified the risk for whale-ship collisions worldwide for four geographically widespread ocean giants that are threatened by shipping: blue, fin, humpback and sperm whales. In a paper published online Nov. 21 in Science, researchers report that global shipping traffic overlaps with about 92% of these whale species鈥� ranges. Only about 7% of areas at highest risk for whale-ship collisions have any measures in place to protect whales from this threat. These measures include speed reductions, both mandatory and voluntary, for ships crossing waters that overlap with whale migration or feeding areas.
