Researchers at Tyndall National Institute have developed a scalable array of electrically driven quantum dots that can generate entangled photons, addressing a key hurdle in quantum computing. This method offers control over photon positions and uses conventional semiconductor fabrication, potentially accelerating the development of practical quantum computers.
Harvard's HouseZero project is retrofitting a pre-1940s house in Cambridge to produce more energy than it uses, setting a new benchmark for sustainable building. The project demonstrates that existing structures can be transformed into ultra-efficient models using smart design and green technology.
Voyager 1's crossing of the heliopause in 2012 sparked debate over whether it truly left the solar system. The probe's measurements show it entered interstellar space, but gravitational and orbital definitions place the boundary much farther out. This article clarifies the scientific distinctions and what the milestone actually means.
President Trump's repeated interest in acquiring Greenland may be linked to the island's melting ice sheet, which is exposing valuable mineral deposits. Analysts suggest this rationale contradicts his public climate change skepticism, while alternative explanations like security or oil lack support.
A property owner in Pombal, Portugal, uncovered bone fragments during construction in 2017, leading to the excavation of a massive sauropod skeleton. The fossil, estimated at 82 feet long and nearly 40 feet tall, is remarkably well-preserved and may be the largest dinosaur ever found in Europe. Researchers from the University of Lisbon and Spanish institutions are studying the remains.
British officials are expected to urge the public to send fewer unnecessary emails to cut carbon emissions, citing a potential annual saving of 18,114 tons. However, experts note this represents just 0.0037% of the UK's total emissions, underscoring the need for larger systemic changes.
Massachusetts legislators have introduced a bill that would require the state to source all its electricity from renewables by 2035 and eliminate fossil fuels across heating and transportation by 2050. The measure also aims to boost clean energy jobs and sends a signal to federal officials amid shifting national energy priorities.
Engineers at the University of California, San Diego, have developed 3D-printed micro-robots, dubbed 'micro-fish,' that can swim through fluids and neutralize toxins or deliver medication. The technology, still in early stages, could one day enable precise treatments in hard-to-reach areas of the body.
An active-duty U.S. Army soldier was arrested for allegedly using classified information to place winning bets on Polymarket about the U.S. invasion of Venezuela, netting over $410,000. The case highlights the risks of prediction markets monetizing sensitive information.
A new U.S. intelligence report warns that China is actively developing capabilities to threaten satellites in orbit, including missiles and lasers. The assessment highlights China's broader push for space leadership, from military systems to a new space station, as the U.S. seeks to maintain its edge.
Newly released documents reveal how Canadian military officials struggled to manage an influx of Pokémon Go players trespassing on bases in 2016. Emails show confusion about the game, from misidentifying PokeStops to humorous attempts to adapt. The documents highlight the unexpected challenges of a viral mobile game.
A five-year European research project has concluded, revealing that robotic bees can infiltrate honeybee colonies and influence their behavior. This breakthrough offers new insights into animal communication and potential strategies for conservation as bee populations face decline.
Columbia University researchers report the first compelling evidence of a moon orbiting a planet outside our solar system, a Jupiter-sized world 4,000 light-years away. The finding, based on data from NASA's Kepler and Hubble telescopes, suggests a large exomoon, though the team urges caution until further observations confirm it.
New research from Harvard University reveals that melting polar ice is not only raising sea levels but also physically deforming Earth's crust, with effects that persist for millennia. The study, published in Geophysical Research Letters, shows that the crust rebounds and warps in ways that can influence ecosystems and geological processes for thousands of years.
The Environmental Protection Agency has dropped the statistical value of a human life to zero in its cost-benefit analyses for industrial pollution limits. The move, which departs from decades of practice, is expected to weaken future air quality standards for ozone and fine particulate matter. Economists warn it could undo public health gains achieved since the Clean Air Act of 1970.
Federal data shows the contiguous U.S. averaged 76.89°F in July, surpassing the 1936 Dust Bowl peak. Scientists link the heat to El Niño and human-caused warming, while drought and wildfires strain the nation. Policy choices on fossil fuels and AI data centers add to the challenge.
This article examines the enduring threat of nuclear weapons, from the 1945 Hiroshima bombing to current U.S. disarmament efforts. It highlights the catastrophic human cost and the ongoing international debate over reducing nuclear stockpiles.
DC Marijuana Justice plans to distribute free cannabis to people getting vaccinated against COVID-19 in Washington, D.C., aiming to boost inoculation rates and push for federal legalization. The group will also provide information on contacting lawmakers to support cannabis reform.
Researchers at MIT have developed a concrete mixture infused with carbon black that functions as a supercapacitor, capable of storing electrical energy. While the current prototype can only power a small LED for 30 hours, the team envisions scaling it up to meet daily household energy needs, potentially transforming building foundations into energy reservoirs.
Beijing's municipal development and reform commission announced that coal use in the capital's plain areas will be nearly eliminated by 2020, with gross coal consumption capped at 5 million tonnes. The plan includes converting all coal-fired boilers to clean energy and boosting renewable energy to over 8 percent of total consumption.
