Electricity-driven undersea reactions may have been important for the emergence of life

Electricity-driven undersea reactions may have been important for the emergence of life

By   July 24, 2019   No comments:

In deep sea hydrothermal vents, water heated by Earth's mantle flows into the ocean, precipitating various minerals, including metal sulfides. These minerals form channels for the vent water, and since the metal sulfides are electrically conductive and the vent and ocean water are compositionally different, an electric current is created. ELSI scientists have shown this current can reduce metal sulfides to metals, which can reduce organic compounds. These reactions could have helped jump-start life's chemistry.

Tobacco-21 laws can lower smoking prevalence in the 18-20 age group

By   July 24, 2019   No comments:

A new study published today by the scientific journal Addiction found that raising the legal age of sale of cigarettes from 18 to 21 in the US was associated with a 39% reduction in the odds of regular smoking in 18- to 20-year-olds who had experimented with cigarettes. The reduction was even greater (50%) in those who had close friends who smoked when they were 16.

The geoengineering of consent: How conspiracists dominate YouTube climate science content

The geoengineering of consent: How conspiracists dominate YouTube climate science content

By   July 24, 2019   No comments:

Using YouTube to learn about climate-change-related topics will expose you to video content that mostly opposes worldwide scientific consensus. That's the finding of a new study, which also reveals that conspiracy theorists have 'hijacked' some scientific terms, such as 'geoengineering,' so that searches provide entirely non-scientific content. Scientists could counteract this by forming alliances with influential YouTubers, politicians and those in popular culture, to ensure scientifically accurate video content reaches the widest-possible audience.

ELSI scientists discover new chemistry that may help explain the origins of cellular life

By   July 22, 2019   No comments:

All life is cellular, but the origins of cellularity remain unknown. Scientists at the Earth-Life Science Institute have discovered that simple organic compounds like glycolic and lactic acid polymerize and self-assemble into cell-sized droplets when dried and rewetted, as might have happened along primitive beaches and drying puddles. These cell-like compartments can trap and concentrate biomolecules, and can merge and separate, forming versatile and heterogeneous cell-like containers possibly critical for the origin of life.

Gun ownership linked to greater incidence of domestic homicides

By   July 21, 2019   No comments:

A new study in the American Journal of Preventive Medicine, published by Elsevier, reveals a unique and strong association between firearm ownership and the risk of domestic homicides. For each 10% increase in household gun ownership rates, the findings show a significant 13% increased incidence of domestic firearm homicide. The homicide risk differed across victim-offender relationships, with nondomestic firearm homicide rising only 2% among firearm owners.
