NASA astronaut Loral O’Hara and two cosmonauts safely arrived at the International Space Station Friday, Sept. 15, bringing its number of residents to 10 for the coming week.

The Soyuz MS-24 spacecraft carrying O’Hara, as well as Oleg Kononenko and Nikolai Chub of Roscosmos, docked to the station’s Rassvet module at 2:53 p.m. EDT. Docking occurred about three hours after the crew’s 11:44 a.m. launch from the Baikonur Cosmodrome in Kazakhstan.

O’Hara, Kononenko, and Chub will join the Expedition 69 crew when hatches open at 5:10 p.m. O’Hara, who is beginning a six-month stay aboard the orbital outpost, and Kononenko and Chub, who will both spend a year on the orbital outpost will work on science and research in technology development, Earth science, biology, and human research for the benefit of all. This marks the first spaceflight for O’Hara, the fifth for Kononenko, and the first for Chub.

Expedition 70 will begin Wednesday, Sept. 27, following the departure of record-breaking NASA astronaut Frank Rubio and Roscosmos cosmonauts Sergey Prokopyev, and Dmitri Petelin. Rubio recently broke the record for longest single spaceflight by an American. Following a yearlong stay aboard the orbiting laboratory, the trio will land in Kazakhstan on Sept. 27, at which point Rubio will have spent a total of 371 days in space—the longest single spaceflight by a U.S. astronaut.

Trump is stripping protections from marine protected areas – why that’s a problem for fishing’s future, and for whales, corals and other ocean life

David Shiffman, Arizona State University The single greatest threat to the diversity of life in our oceans over the past 50 years, more than climate change or plastic pollution, has been unsustainable fishing practices. In much of the ocean, there is little to no regulation or oversight of commercial fishing or other human activities. That’s part of the reason about a tenth of marine plant and animal species are considered threatened or at risk. It’s also why countries around the world have been creating marine protected areas. These protected areas, covering over 11.6 million square miles (30 million square kilometers) in 16,000 locations, offer refuge away from human activities for a wide variety of living creatures, from corals to sea turtles and whales. They give fish stocks a place to thrive, and those fish spread out into the surrounding waters, which helps fishing industries and local economies. In the U.S., however, marine protection is being dismantled by President Donald Trump.

Trump issued a proclamation on April 17, 2025, titled “Unleashing American commercial fishing in the Pacific,” ordering the removal of key protections to allow commercial fishing in parts of a nearly-500,000-square-mile marine protected area called the Pacific Island Heritage National Marine Monument. He also called for a review of all other marine national monuments to decide if they should be opened to commercial fishing too. In addition, the Trump administration is proposing to redefine “harm” under the Endangered Species Act in a way that would allow for more damage to these species’ habitats. I’m a marine biologist and scuba diver, and it’s no accident that all my favorite dive sites are within marine protected areas. I’ve found what scientific studies from across the world show: Protected areas have much healthier marine life populations and healthier ecosystems.

What’s at risk in the Pacific

The Pacific Island Heritage National Marine Monument, about 750 miles west of Hawaii, is dotted by coral reefs and atolls, with species of fish, marine mammals and birds rarely found anywhere else. It is home to protected and endangered species, including turtles, whales and Hawaiian monk seals. Palmyra Atoll and Kingman Reef, both within the area, are considered among the most pristine coral reefs in the world, each providing habitats for a wide range of fish and other species. These marine species are able to thrive there and spread out into the surrounding waters because their habitats have been protected.

President George W. Bush, a conservative Republican, created this protected area in 2009, restricting fishing there, and President Barack Obama later expanded it. Trump, whose administration has made no secret of its aim to strip away environmental protections across the country’s land and waters, is now reopening much of the marine protected area to industrial-scale fishing.

The risks from industrial fishing

When too many fish are killed and too few young fish are left to replace them, it’s considered overfishing, and this has become a growing problem around the world. In 1974, about 10% of the world’s fish stocks were overfished. By 2021, that number had risen to 37.7%, according to the United Nations Food and Agriculture Organization’s annual State of Fisheries and Aquaculture Report.

Modern industrial-scale fishing practices can also harm other species. Bycatch, or catching animals that fishermen don’t want but are inadvertently caught up in nets and other gear, is a threat to many endangered species. Many seabirds, sea turtles and whales die this way each year. Some types of fishing gear, such as trawls and dredges that drag along the sea floor to scoop up sea life, can destroy ocean habitat itself. Without regulations or protected areas, fishing can turn into a competitive free-for-all that can deplete fish stocks.

How marine protected areas protect species

Marine protected areas are designed to safeguard parts of the ocean from human impacts, including offshore oil and gas extraction and industrial fishing practices. Studies have found that these areas can produce many benefits for both marine life and fishermen by allowing overfished species to recover and ensuring their health for the future. A decade after Mexico established the Cabo Pulmo protected area, for example, fish biomass increased by nearly 500%.
How marine protected areas help marine life and local economies.
Successful marine protected areas tend to have healthier habitats, more fish, more species of fish, and bigger fish than otherwise-similar unprotected areas. Studies have found the average size of organisms to be 28% bigger in these areas than in fished areas with no protections. How many babies a fish has is directly related to the size of the mother. All of this helps create jobs through ecotourism and support local fishing communities outside the marine protected area. Marine protected areas also have a “spillover effect” – the offspring of healthy fish populations that spawn inside these areas often spread beyond them, helping fish populations outside the boundaries thrive as well. Ultimately, the fishing industry benefits from a continuing supply. And all of this happens at little cost.

A need for more protected areas, not fewer

Claims by the Trump administration that marine protected areas are a heavy-handed restriction on the U.S. fishing industry do not hold water. As science and my own experience show, these refuges for sea life can instead help local economies and the industry by allowing fish populations to thrive. For the future of the planet’s whales, sea turtles, coral reefs and the health of fishing itself, scientists like me recommend creating more marine protected areas to help species thrive, not dismantling them.The Conversation David Shiffman, Faculty Research Associate in Marine Biology, Arizona State University This article is republished from The Conversation under a Creative Commons license.

US earthquake safety relies on federal employees’ expertise

Jonathan P. Stewart, University of California, Los Angeles and Lucy Arendt, St. Norbert College Earthquakes and the damage they cause are apolitical. Collectively, we either prepare for future earthquakes or the population eventually pays the price. The earthquakes that struck Myanmar on March 28, 2025, collapsing buildings and causing more than 3,000 deaths, were a sobering reminder of the risks and the need for preparation. In the U.S., this preparation hinges in large part on the expertise of scientists and engineers in federal agencies who develop earthquake hazard models and contribute to the creation of building codes designed to ensure homes, high-rises and other structures won’t collapse when the ground shakes. Local communities and states decide whether to adopt building code documents. But those documents and other essential resources are developed through programs supported by federal agencies working in partnership with practicing engineers and earthquake experts at universities. This essential federal role is illustrated by two programs that we work closely with as an earthquake engineer and a disaster management expert whose work focuses on seismic risk.

Improving building codes

First, seismologists and earthquake engineers at the U.S. Geological Survey, or USGS, produce the National Seismic Hazard Model. These maps, based on research into earthquake sources such as faults and how seismic waves move through the earth’s crust, are used to determine the forces that structures in each community should be designed to resist. A steering committee of earthquake experts from the private sector and universities works with USGS to ensure that the National Seismic Hazard Model implements the best available science.

In this 2023 update of the national seismic risk map, red areas have the greatest chance of a damaging earthquake occurring within 100 years. USGS
Second, the Federal Emergency Management Agency, FEMA, supports the process for periodically updating building codes. That includes supporting the work of the National Institute of Building Sciences’ Provisions Update Committee, which recommends building code revisions based on investigations of earthquake damage. More broadly, FEMA, the USGS, the National Institute of Standards and Technology and the National Science Foundation work together through the National Earthquake Hazards Reduction Program to advance earthquake science and turn knowledge of earthquake risks into safer standards, better building design and education. Some of those agencies have been threatened by potential job and funding cuts under the Trump administration, and others face uncertainty regarding continuation of federal support for their work. It is in large part because of the National Seismic Hazard Model and regularly updated building codes that U.S. buildings designed to meet modern code requirements are considered among the safest in the world, despite substantial seismic hazards in several states. This paradigm has been made possible by the technical expertise and lack of political agendas among the federal staff. Without that professionalism, we believe experts from outside the federal government would be less likely to donate their time. The impacts of these and other programs are well documented. We can point to the limited fatalities from U.S. earthquakes such as the 1989 Loma Prieta earthquake near San Francisco, the 1994 Northridge earthquake in Los Angeles and the 2001 Nisqually earthquake near Seattle. Powerful earthquakes in countries lacking seismic preparedness, often due to lack of adoption or enforcement of building codes, have produced much greater devastation and loss of life.

The US has long relied on people with expertise

These programs and the federal agencies supporting them have benefited from a high level of staff expertise because hiring and advancement processes have been divorced from politics and focused on qualifications and merit. This has not always been the case. For much of early U.S. history, federal jobs were awarded through a patronage system, where political loyalty determined employment. As described in “The Federal Civil Service System and The Problem of Bureaucracy,” this system led to widespread corruption and dysfunction, with officials focused more on managing quid pro quo patronage than governing effectively. That peaked in 1881 with President James Garfield’s assassination by Charles Guiteau, a disgruntled supporter who had been denied a government appointment. The passage of the Pendleton Act by Congress in 1883 shifted federal employment to a merit-based system. This preference for a merit-based system was reinforced in the Civil Service Reform Act of 1978. It states as national policy that “to provide the people of the United States with a competent, honest, and productive workforce … and to improve the quality of public service, Federal personnel management should be implemented consistent with merit system principles.” The shift away from a patronage system produced a more stable and efficient federal workforce, which has enabled improvements in many critical areas, including seismic safety and disaster response.

Merit-based civil service matters for safety

While the work of these federal employees often goes unnoticed, the benefits are demonstrable and widespread. That becomes most apparent when disasters strike and buildings that meet modern code requirements remain standing. A merit-based civil service is not just a democratic ideal but a proven necessity for the safety and security of the American people, one we hope will continue well into the future. This can be achieved by retaining federal scientists and engineers and supporting the essential work of federal agencies.

Controlled burns reduce wildfire risk, but they require trained staff and funding − this could be a rough year

Published

on

Controlled burns

Red skies in August, longer fire seasons and checking air quality before taking my toddler to the park. This has become the new norm in the western United States as wildfires become more frequent, larger and more catastrophic. As an ecologist at the University of Colorado Boulder, I know that fires are part of the natural processes that forests need to stay healthy. But the combined effects of a warmer and drier climate, more people living in fire-prone areas and vegetation and debris built up over years of fire suppression are leading to more severe fires that spread faster. And that’s putting humans, ecosystems and economies at risk. To help prevent catastrophic fires, the U.S. Forest Service issued a 10-year strategy in 2022 that includes scaling up the use of controlled burns and other techniques to remove excess plant growth and dry, dead materials that fuel wildfires. However, the Forest Service’s wildfire management activities have been thrown into turmoil in 2025 with funding cuts and disruptions and uncertainty from the federal government. The planet just saw its hottest year on record. If spring and summer 2025 are also dry and hot, conditions could be prime for severe fires again.

More severe fires harm forest recovery and people

Today’s severe wildfires have been pushing societies, emergency response systems and forests beyond what they have evolved to handle. Extreme fires have burned into cities, including destroying thousands of homes in the Los Angeles area in 2025 and near Boulder, Colorado, in 2021. They threaten downstream public drinking water by increasing sediments and contaminants in water supplies, as well as infrastructure, air quality and rural economies. They also increase the risk of flooding and mudslides from soil erosion. And they undermine efforts to mitigate climate change by releasing carbon stored in these ecosystems. In some cases, fires burned so hot and deep into the soil that the forests are not growing back. While many species are adapted to survive low-level fires, severe blazes can damage the seeds and cones needed for forests to regrow. My team has seen this trend outside of Fort Collins, Colorado, where four years after the Cameron Peak fire, forests have still not come back the way ecologists would expect them to under past, less severe fires. Returning to a strategy of fire suppression − or trying to “go toe-to-toe with every fire” − will make these cases more common.

Proactive wildfire management can help reduce the risk to forests and property. Measures such as prescribed burns have proven to be effective for maintaining healthy forests and reducing the severity of subsequent wildfires. A recent review found that selective thinning followed by prescribed fire reduced subsequent fire severity by 72% on average, and prescribed fire on its own reduced severity by 62%.
Four sets of illustrations. The most severe fires happened with no treatment. Thinning helps some. Prescribed burning keeps fires burning lower at the forest floor.

But managing forests well requires knowing how forests are changing, where trees are dying and where undergrowth has built up and increased fire hazards. And, for federal lands, these are some of the jobs that are being targeted by the Trump administration. Some of the Forest Service staff who were fired or put in limbo by the Trump administration are those who do research or collect and communicate critical data about forests and fire risk. Other fired staff provided support so crews could clear flammable debris and carry out fuel treatments such as prescribed burns, thinning forests and building fire breaks. Losing people in these roles is like firing all primary care doctors and leaving only EMTs. Both are clearly needed. As many people know from emergency room bills, preventing emergencies is less costly than dealing with the damage later.

Logging is not a long-term fire solution

The Trump administration cited “wildfire risk reduction” when it issued an emergency order to increase logging in national forests by 25%. But private − unregulated − forest management looks a lot different than managing forests to prevent destructive fires. Logging, depending on the practice, can involve clear-cutting trees and other techniques that compromise soils. Exposing a forest’s soils and dead vegetation to more sunlight also dries them out, which can increase fire risk in the near term.

In general, logging that focuses on extracting the highest-value trees leaves thinner trees that are more vulnerable to fires. A study in the Pacific Northwest found that replanting logged land with the same age and size of trees can lead to more severe fires in the future.

Research and data are essential

For many people in the western U.S., these risks hit close to home. I’ve seen neighborhoods burn and friends and family displaced, and I have contended with regular air quality warnings and red flag days signaling a high fire risk. I’ve also seen beloved landscapes, such as those on Cameron Peak, transform when conifers that once made up the forest have not regrown.

My scientific research group and collaborations with other scientists have been helping to identify cost-effective solutions. That includes which fuel-treatment methods are most effective, which types of forests and conditions they work best in and how often they are needed. We’re also planning research projects to better understand which forests are at greatest risk of not recovering after fires. This sort of research is what robust, cost-effective land management is based on. When careful, evidence-based forest management is replaced with a heavy emphasis on suppressing every fire or clear-cutting forests, I worry that human lives, property and economies, as well as the natural legacy of public lands left to every American, are at risk.The Conversation Laura Dee, Associate Professor of Ecology, University of Colorado Boulder This article is republished from The Conversation under a Creative Commons license.
