The Standard Model of particle physics, which describes the fundamental building blocks of matter, emerged from a series of discoveries spanning over a century. From J.J. Thomson's identification of the electron in 1897 to Murray Gell-Mann's quark theory in the 1960s, this article traces the key experiments and insights that shaped our understanding of the subatomic world.
A new study involving 20,000 participants in China reveals that cumulative exposure to air pollution can reduce cognitive performance equivalent to a year of education, with stronger effects on older adults and men. The research, published in PNAS, adds to growing evidence of pollution's harm to brain health.
New research confirms Greenland's coastal glaciers and ice caps have crossed an irreversible melting threshold, with complete loss projected by 2100. This will contribute a 3.8 cm rise in sea levels, underscoring the urgent need for climate action.
Two UN reports released ahead of COP26 reveal that current national climate pledges are insufficient, projecting a 16% rise in emissions and a 4.9°F temperature increase by 2100. The reports urge G20 nations to accelerate net-zero targets, warning of severe consequences if action is delayed.
As renewable energy sources like solar and wind expand their share of power grids, the environmental benefits of electric vehicles grow. In the UK, emissions from charging a Tesla Model S have dropped by half since 2012, according to new data. The trend signals a shift toward cleaner driving as grids decarbonize.
An international team led by a University of New Mexico physicist has measured a quantum force that acts on nanoparticles from a distance, even when they are not in contact with a surface. The finding could reshape how engineers design nanoscale devices for computing and healthcare.
Researchers from Oak Ridge and Lawrence Livermore National Laboratories and General Atomics published simulations in Nuclear Fusion showing a compact tokamak could produce 200 MW of net electricity, enough for 40,000 homes. The design compresses plasma to achieve a net energy gain, though a working reactor remains at least a decade away.
Marine archaeologists have uncovered a 400-foot-long stone wall submerged off Brittany, dating to around 5,000 BC. The structure, possibly a fish trap or flood defense, offers rare insight into prehistoric coastal life. Its parallels to modern climate-driven sea-level rise make the find particularly resonant.
A new ComRes poll of 2,045 British adults reveals that 64% now accept climate change is happening and primarily caused by human activity, up from 57% in 2014 and 59% in 2015. The survey, commissioned by the Energy and Climate Information Unit, also shows widespread concern about impacts on wildlife and flooding.
A new study warns that a major blackout during a severe heat wave in a U.S. city could kill thousands and send hundreds of thousands to hospitals. Phoenix faces the highest risk due to its extreme temperatures and heavy reliance on air conditioning. Experts call for urgent infrastructure upgrades to prevent a 'Katrina of extreme heat.'
First Light, a UK-based startup, says it has demonstrated a novel fusion approach using a high-speed projectile to compress fuel targets, a method that could lead to affordable, clean energy. The company claims a viable route to commercial fusion, though it has yet to achieve net energy gain, a milestone that remains elusive for the field.
Apple's annual climate disclosure to CDP suggests the company could gain customer loyalty as extreme weather events become more frequent. The tech giant's filing highlights the iPhone's role in emergencies and the potential for increased brand value, despite the broader environmental crisis.
New York City has become the first U.S. city to mandate that building owners cut greenhouse gas emissions, targeting a 7% citywide reduction by 2035. The rules, announced by Mayor Bill de Blasio, require efficiency upgrades for large buildings, with penalties for non-compliance, and aim to honor the Paris Agreement despite federal withdrawal.
A MinutePhysics video explains why perfect cloning is mathematically impossible at the quantum level, using Schrodinger's cat to illustrate superposition. The no-cloning theorem, proven decades ago, means any attempt to copy a quantum state inevitably alters it, a principle with deep implications for quantum computing and cryptography.
Researchers grew a high-quality rubrene film on a hexagonal boron nitride substrate, achieving record charge transport performance. The interface between substrate and film is key to nucleation, and graphene contacts enabled a field-effect transistor structure for testing.
Researchers at the City University of New York have found that stacking exactly two layers of graphene creates a material that hardens to diamond-like stiffness upon impact. The discovery, published in Nature Nanotechnology, could lead to thinner, lighter armor and wear-resistant coatings.
Climeworks, a Swiss company, is set to open the world's first commercial carbon capture plant near Zurich by late 2025, filtering CO2 from the air and selling it to agricultural and beverage industries. The facility will extract 900 tonnes of CO2 annually, equivalent to the emissions of about 200 cars, though skeptics question the technology's scalability and cost.
A microscopic animal, a bdelloid rotifer, was revived after spending 24,000 years frozen in Siberian permafrost, setting a record for multicellular organisms surviving cryptobiosis. The research, published in Current Biology, shows that complex lifeforms can endure extreme cold and return to life, offering insights into long-term preservation.
Hurricane Milton, a historic Category 5 storm, is barreling toward Florida's west coast, prompting mass evacuations. Radar images show the storm as a massive red blob, indicating extreme rainfall and intensity. Although it may weaken to a Category 3 before landfall, officials warn of life-threatening conditions.
Researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory and Princeton University have developed a general theory of plasmoid instability, explaining the explosive acceleration of magnetic reconnection. This advance could sharpen predictions of solar flares and space weather, and it offers a pathway to strengthening magnetic barriers in tokamak fusion reactors, moving fusion energy closer to practical reality.
