Human activity has been causing climate change for nearly two centuries
An international research project has found human activity has been causing global warming for almost two centuries, proving human-induced climate change is not just a twentieth century phenomenon. The study found warming began during the early stages of the Industrial Revolution and is first detectable in the Arctic and tropical oceans around the 1830s, much earlier than scientists had expected.

Solar-powered Ring Garden combines desalination, agriculture for drought-stricken California
With roughly 80 percent of California’s already-scarce water supply going to agriculture, it is crucial for the state to embrace new technologies that shrink the amount of water required to grow food. Alexandru Predonu has designed an elegant solution which uses solar energy to power a rotating desalination plant and farm that not only produces clean drinking water for the city of Santa Monica, but also food crops — including algae.

Data shows growing political polarization on climate change
New research discusses the increasing partisan polarization of American attitudes toward climate change. The article details the escalation of partisan polarization, particularly toward environmental protection and climate change, over the past few decades in America, showing an increasing gap between self-identified Republicans’ and Democrats’ attitudes toward human-caused climate change. While Democrats have increasingly accepted the reality and seriousness of climate change over the past two decades, Republicans have become more skeptical.

Assessing climate change vulnerability in urban America
Impacts of climate change – rising sea levels, heat waves, rising rates of diseases caused by ticks, fleas, and mosquitoes, and many more — will affect cities across the country. One of the first efforts systematically to assess how cities are preparing for climate change shows that city planners have yet fully to assess their vulnerability to climate change, leaving serious risks unaddressed. Most city planners have yet to prepare for climate-related risks and the consequences.

Pace of Earth’s warming “unprecedented in 1,000 years”: NASA
The warming of the planet is proceeding at a pace not experienced within the past 1,000 years, making it “very unlikely” to keep warming to 1.5 degrees Celsius – the goal agreed by nations at the Paris climate summit last December. Recent research found that continuing current levels of carbon dioxide emissions for just five more years will eliminate any chance of restraining temperatures to a 1.5C increase and avoid runaway climate change.

Large-scale metamaterials could earthquake-proof buildings in tremor-prone regions
Metamaterials – artificial structures that exhibit extraordinary vibrational properties – could come to the rescue of regions threatened by earthquakes, according to new research. The study, performed by researchers in Europe and involving detailed computer simulations, shows that large-scale metamaterials can attenuate the energy and amplitude of harmful low-frequency vibrations associated with seismic shocks.

Nuclear forensics summer program trains students for a future in nuclear security
A sure sign of summer is the return of interns to the Lawrence Livermore campus. Students interact with premier researchers and access equipment and facilities not available anywhere else, while scientists lay groundwork for advancing their fields. LLNL runs an eight-week summer internship for students interested in nuclear science and its range of specialties — nuclear forensics, environmental radiochemistry, nuclear physics, and beyond. Together, these disciplines support the laboratory’s nuclear security mission through analysis of nuclear processes and properties.

Rising seas threaten 1.9 million U.S. homes with current value of $882 billion
Typically when we talk about “underwater” homes, we are referring to negative equity. But there is a more literal way a home can be underwater: Rising sea levels, and the flooding likely to come with them, could inundate millions of U.S. homes worth hundreds of billions of dollars. If sea levels rise as much as climate scientists predict by the year 2100, almost 300 U.S. cities would lose at least half their homes, and 36 U.S. cities would be completely lost. The total combined current value of all homes at risk of being underwater with a 6-feet rise in sea levels is $882 billion.

Presidential candidates may be psychopaths – but this is not necessarily a bad thing
Oxford University’s Dr. Kevin Dutton has spent much of his career looking at psychopaths and researching psychopathic traits, identifying those which can be of benefit and those which can lead to incarceration. He contends that being a psychopath is not an all-or-nothing affair. Instead, psychopathy is on a spectrum along which each of us has our place. In a new study, Dutton finds that Donald Trump ranks above Adolf Hitler and only just below Idi Amin, Saddam Hussein, and Henry VIII. Hillary Clinton ranks between Napoleon and Nero.

Robot, drones to help collect crop testing data to bolster agricultural production
A rumbling robot and several high-flying drones recently made an on-site appearance at Clemson University to burrow through and buzz above fifteen acres of experimental sorghum plots containing more than 2,800 replicated entries. The space-age devices are part of a collaborative project with Clemson University and other partners designed to significantly enhance the ease and frequency of data collection for crop testing in ways that will eventually benefit all agricultural production in South Carolina and around the world.

Global warming would make most cities too hot, humid to host summer Olympics
The future of the summer Olympics may be in jeopardy because of rising heat and humidity due to climate change. By 2085, only eight Northern Hemisphere cities outside of Western Europe are likely to be cool enough to host the summer games. The authors considered only cities with at least 600,000 residents, the size considered necessary for hosting the games. Cities with elevations over a mile above sea level were omitted as such an altitude (for example, Mexico City in 1968) faced challenges of their own.

Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
A Brief History of Federal Funding for Basic Science
Biomedical science in the United States is at a crossroads. For 75 years, the federal government has partnered with academic institutions, fueling discoveries that have transformed medicine and saved lives. Recent moves by the Trump administration — including funding cuts and proposed changes to how research support is allocated — now threaten this legacy.

Ukraine Drone Strikes on Russian Airbase Reveal Any Country Is Vulnerable to the Same Kind of Attack
Air defense systems are built on the assumption that threats come from above and from beyond national borders. But Ukraine’s coordinated drone strike on 1 June on five airbases deep inside Russian territory exposed what happens when states are attacked from below and from within. In low-level airspace, visibility drops, responsibility fragments, and detection tools lose their edge. Drones arrive unannounced, response times lag, coordination breaks.
