On January 1, 2017, dense smog enveloped major Chinese cities, forcing flight cancellations and highway closures. PM2.5 levels exceeded 500 micrograms per cubic meter—50 times WHO guidelines—prompting red alerts in 24 cities. Officials blame winter heating, industrial emissions, and El Niño, while outlining measures to curb pollution.
Researchers from Duke University, Ohio State University, and Oak Ridge National Laboratory have demonstrated a quantum key distribution system that encrypts data at megabit-per-second rates, five to ten times faster than current methods. By encoding two bits per photon and using high-speed detectors, the system could support encrypted calls and video streaming, bringing quantum-secured communication closer to practical use.
Ukrainian officials report Russian forces withdrew from Chernobyl after showing symptoms of radiation sickness, raising concerns about nuclear safety amid the conflict. The IAEA plans to send a mission, while experts question the scale of exposure.
SpaceX has introduced Starshield, a satellite service tailored for government and military use, leveraging its Starlink network. The program aims to support national security missions with secure payload hosting and inter-satellite laser communications. This move solidifies SpaceX's role in the defense sector, raising questions about space militarization.
MIT researchers have achieved superconductivity in pristine graphene by stacking two layers at a 1.1-degree twist and applying an electric field. This marks the first time the phenomenon has been observed without chemical doping, opening possibilities for room-temperature superconductors.
The U.S. military is investigating ways to clear radioactive particles from space after a nuclear blast, fearing that an attack by North Korea could cripple American satellites. Experiments are underway to test radiation belt remediation, a process that could drain harmful electrons from the atmosphere. Officials warn of a potential 'Pearl Harbor of space' if no defense is found.
A Pemex-operated oil and gas platform in the Gulf of Mexico, site of a 2021 fire, leaked roughly 44,000 tons of methane in August. The release, equivalent to emissions from hundreds of thousands of homes, underscores the climate impact of fossil fuel infrastructure.
A global analysis published in Neurology links over 500,000 stroke deaths in 2023 to extreme temperatures, with cold weather being the primary driver. The study highlights regional disparities, with central Asia facing the highest death rate, and underscores the growing health burden as temperatures become more erratic.
The Los Angeles City Council has approved a measure directing the Department of Water and Power to study how the city can transition to 100% clean energy. The move follows years of air quality problems and aligns with a broader push among cities to eliminate fossil fuels. The study will involve local universities and energy experts.
A helium-filled wind turbine designed by MIT spinoff Altaeros Energies will float 1,000 feet above Fairbanks, Alaska, for 18 months, generating electricity for over a dozen off-grid homes. The $1.3 million grant from the Alaska Energy Authority supports testing of the buoyant system, which also aims to provide data and cell coverage in remote areas.
Recent temperature spikes in both Antarctica and the Arctic have scientists concerned, with readings up to 90 degrees above normal in some areas. The simultaneous warming, driven by atmospheric moisture and a bomb cyclone, underscores the urgency of climate action.
A U.S. Department of Energy report shows solar power employed 374,000 people in 2015–2016, more than oil, gas, and coal combined at 187,117. Solar's construction-driven job growth reflects a broader shift in the electric power sector's employment profile.
Scientists at the University of Oulu have identified a perovskite mineral, KBNNO, that can simultaneously convert sunlight, heat, and mechanical movement into electricity. This multi-energy approach could lead to self-powered sensors and devices, reducing reliance on traditional batteries. The team is already working on an improved version and a prototype device.
In the U.S., unsubsidized onshore wind is expected to become cost-competitive with fossil-fuel power plants within 10 years, according to Bloomberg New Energy Finance analyst Alex Morgan. Wind already supplied 5.6% of U.S. electricity in 2016, more than double the 2010 share, with major corporations driving demand.
A GTM Research study predicts global solar construction costs will decline 27% by 2022, driven by market globalization. India leads with a record low of 65 cents per watt, while Japan remains the most expensive. The report also raises concerns about quality and labor practices in low-cost markets.
Researchers at Princeton Plasma Physics Laboratory have upgraded a fusion reactor with a lithium wall coating, which absorbs stray particles and helps maintain the extreme conditions needed for fusion. The experiment is set to test hotter plasmas and stronger magnetic fields, potentially advancing practical fusion power.
The U.S. Navy has yet to identify the object its nuclear submarine USS Connecticut struck in the South China Sea earlier this month, causing damage and injuries. Beijing is pressing for answers, accusing Washington of a cover-up, while the Pentagon insists it has been transparent about the incident.
As Russian forces advance in Ukraine, experts warn that the country's 15 nuclear reactors face an unprecedented safety risk. The IAEA chief has urged restraint, while physicists note that reactors are not built to withstand war-zone conditions, raising concerns about accidental damage and radioactive fallout.
Chinese firm HiCloud has activated a 24 MW underwater data center off Shanghai, drawing 95% of its power from offshore wind and using ocean currents for cooling. The $226 million facility aims to cut energy use by 23% compared to land-based centers, marking a world-first commercial-scale deployment.
Researchers at RMIT University have developed a method to create atomically thin oxide layers from liquid metals, a feat not found in nature. The breakthrough could lead to faster, more energy-efficient electronics and touch screens, and may apply to a third of the periodic table.
