ALMA observations reveal the interstellar comet 3I/ATLAS is unusually methanol-rich, with methanol originating from both the nucleus and coma. This chemical fingerprint suggests formation under conditions different from those of Solar System comets and provides a glimpse into the chemistry of distant star systems, with more interstellar visitors anticipated as powerful observatories come online.
ALMA observations of the interstellar object 3I/ATLAS reveal an unusually high methanol abundance in its coma and core—among the highest seen in comets—paired with a high methanol-to-hydrogen cyanide ratio, indicating distinctive formation conditions in that distant system. The methanol appears to come from both the core and the coma, and future observations with advanced telescopes could help explain the object’s origin as it exits the solar system.
ALMA observations show the interstellar comet 3I/ATLAS is unusually rich in methanol, released from both the nucleus and icy grains in the coma. The methanol-to-hydrogen cyanide ratio is higher than in Solar System comets, suggesting 3I/ATLAS formed under colder or chemically different conditions in another planetary system, providing a chemical fingerprint from a different star.
Observations of interstellar comet 3I/Atlas show its coma is unusually rich in methanol—up to four times typical levels—along with carbon dioxide and other organics, suggesting formation in a colder or chemically distinct environment. The study, based on ALMA data, indicates methanol (and other gases) may be released from both the nucleus and sublimating icy grains in a hyperactive comet, supporting a natural origin. As it travels away from the Sun at about 60 km/s, 3I/Atlas reinforces that more interstellar visitors are likely to be found with advancing detection capability.
Brazil is on high alert after a wave of suspected methanol poisoning from tainted alcohol has resulted in deaths, blindness, and comas, prompting health warnings and a crackdown on illicit spirits, with investigations into organized crime involvement.
At least 19 people have died from suspected methanol poisoning after consuming tainted homemade alcohol in Russia's Leningrad region, highlighting ongoing issues with counterfeit spirits and alcohol-related deaths in the country and globally.
Researchers detected methanol and its isotopes in the gas around the young star HD 100453, providing insights into the organic ingredients necessary for life and supporting the idea that comets may have delivered these materials to Earth, aiding in the development of life.
Researchers detected methanol and its isotopes in the disk of a young star, HD 100453, providing insights into the organic ingredients necessary for life and supporting the idea that comets delivered these materials to Earth, potentially aiding in the development of life.
Astronomers discovered rare isotopes of methanol in the gas around the young star HD 100453, providing insights into the organic ingredients available for planet formation and the potential origins of life, with implications for understanding how complex molecules necessary for life may develop in star systems.
A recent outbreak of methanol poisoning in Vang Vieng, Laos, has resulted in the deaths of six tourists, prompting international warnings about the dangers of tainted alcohol. Methanol, a toxic industrial alcohol, can be lethal in small amounts and is sometimes used in drinks due to its low cost. The U.S., U.K., and Australia have issued travel advisories, urging tourists to purchase alcohol only from licensed vendors and to be vigilant for signs of tampering. Methanol poisoning can mimic regular intoxication but leads to severe symptoms and requires immediate medical attention.
A series of methanol poisonings in Laos has raised health concerns, prompting authorities to investigate the source and spread awareness about the dangers of consuming contaminated alcohol. Methanol, a toxic substance, can cause severe health issues or even death if ingested. The incidents highlight the need for stricter regulations and public education on alcohol safety.
British lawyer Simone White died in Laos from suspected methanol poisoning after consuming alcohol in Vang Vieng, a popular backpacking destination. Her death is part of a series of similar incidents affecting tourists, with six fatalities reported. White's parents expressed their devastation, describing her as a vibrant and generous person. Methanol, often found in bootleg alcohol, is highly toxic and can be fatal even in small amounts. Investigations are ongoing, with the manager of a hostel where some victims stayed being questioned by police.
The FDA has issued a recall for 40 lots of Aruba Aloe Hand Sanitizer Gel Alcohol 80% and Aruba Aloe Alcoholada Gel due to the presence of methanol, which can cause serious health issues including coma, seizures, and blindness. Customers are advised to stop using the products and discard them. The affected products were distributed between May 1, 2021, and Oct. 7, 2023, and were sold in the United States online through Aruba Aloe Balm N.V.'s website.
Researchers have developed a material consisting of copper anchored on nanocrystalline carbon nitride, which, when exposed to sunlight, can efficiently convert CO2 into methanol, a green fuel. This breakthrough paves the way for creating sustainable fuels and reducing the impact of carbon dioxide, the primary contributor to global warming. The new catalyst, made of abundant elements like carbon, nitrogen, and copper, demonstrates high efficiency and selectivity, offering a promising pathway for the development of highly tunable catalysts at the nanoscale for CO2 conversion.
The global shipping industry is exploring greener technologies to mitigate its significant contribution to climate change. Danish shipping giant Maersk has introduced the first ships powered by green methanol, which can reduce greenhouse gas emissions by 100 tons per day. However, the adoption of greener fuels faces challenges, including the need for new ships and infrastructure, limited production of green methanol, and higher costs compared to conventional fuels. The industry is also awaiting global regulations from the International Maritime Organization to level the playing field and incentivize the transition to low-carbon fuels. While progress is being made, there is still a long way to go to decarbonize the vast fleet of cargo ships that currently operate worldwide.
