- 1Earth absorbing heat equal to four Hiroshima bombs every secondβClimate is accumulating 4 Hiroshima atomic bombs worth of heat per second
A widely shared explainer quantifies the pace of global warming: the climate system is gaining heat equivalent to roughly four Hiroshima atomic bombs per second. The comparison, popularized by climate scientists to make ocean heat uptake tangible, is being used to underline how much excess energy greenhouse gases are trapping in oceans and atmosphere.
- 2Why Pickles Glow When You Electrocute ThemβWhy Pickles Light Up When You Electrocute Them https://gizmodo.com/why-pickles-light-up-when-you-electrocute-them-200082
Gizmodo explains the classic physics demonstration in which a pickle plugged into household current glows and sparks. Sodium ions in the brine conduct electricity, and excited sodium atoms emit the same yellow-orange light as street lamps. The article walks through the science of the eerie glow, reviving a popular classroom and party-trick experiment.

Physicists report a tabletop experiment using ultracold atoms to simulate the creation of particles, mimicking processes that normally occur in extreme environments such as the early universe or strong quantum fields. By controlling cold atomic gases, researchers can model quantum field behavior in the lab, offering a new way to test ideas that are otherwise out of reach of direct experiments.

A Nature retrospective revisits the 1966 Nobel Prize in Physics, awarded to Alfred Kastler for the discovery and development of optical methods for studying atomic spectra, work known as optical pumping. The piece highlights how the achievement rested on collaboration across laboratories and laid foundations for later developments in atomic physics and laser science.
- 5Physicists unveil the most accurate atomic clock ever builtβPhysicists unveil the most accurate atomic clock ever β and it could literally redefine the second
Physicists have announced the most accurate atomic clock ever created, a device so precise it could prompt a redefinition of the second itself. The breakthrough pushes timekeeping beyond the limits of the current caesium standard, opening the door to more exact navigation, fundamental physics tests and a future redefinition of the SI unit of time based on optical clocks.

The 1986 Nobel Prize in Physics is being revisited for honouring the breakthrough that let scientists see individual atoms using electrons. The work established electron-based imaging as a foundation of modern microscopy and materials science, allowing researchers to observe atomic structure directly rather than inferring it.
- 7ATLAS collaboration reports new results on nuclear structureβATLAS gets an edge on nuclear structure
The ATLAS experiment at CERN has announced new findings described as giving researchers an edge on nuclear structure. The result is presented as an advance in understanding how protons and neutrons behave inside atomic nuclei when probed at high energies. Details of the measurement and its implications are still limited in the initial announcement.

Fifth Wall co-founder Brendan Wallace spoke with Forbes about Atoms, the new proptech venture launched by former Uber chief executive Travis Kalanick. Wallace discussed Kalanick's return to technology, how Atoms fits into the property technology landscape, and his views on the future of real estate innovation and investment.

The International Atomic Energy Agency has reported Iran to the United Nations Security Council, according to the Arms Control Association. The referral is a significant escalation in international oversight of Iran's nuclear programme, giving the Security Council a formal role in addressing Iran's compliance with nuclear safeguards obligations. Such a move could open the way to renewed diplomatic pressure or further measures against Tehran.
- 10AI development compared to Manhattan Project, and rejectedβNo, AI is not similar to the Manhattan Project
The Financial Times argues that artificial intelligence development should not be likened to the Manhattan Project, the secret US programme that built the first atomic bomb. The comparison has circulated as governments and companies frame AI as a national-security priority. The piece pushes back against the framing, suggesting the analogy distorts public understanding of what AI research is and how it is being pursued.
