12:30a	Blue Light Like That From Smartphones Linked To Some Cancers, Study Finds A new study, published Monday in the journal Environmental Health Perspectives, found that exposure to the kind of blue light emitted by outdoor LEDs, smartphones and tablets may increase your risk of breast or prostate cancer. The study compared previous exposure to artificial lights at night between approximately 2,000 breast or prostate cancer patients and approximately 2,000 controls living in Barcelona and Madrid. Slashdot reader al0ha writes: This study seems to say that exposure to LED light temperatures higher than 3,000 Kelvin suppresses melatonin because it contains increased blue light, and at least one city (Davis, California) has gone to the expense of removing higher temperature LED lights and replacing them with ones that have lower color temperatures. Specifically, the study found that "those exposed to high levels of outdoor blue light at night had around a 1.5-fold higher risk of developing breast cancer and a twofold higher risk of developing prostate cancer, compared with those who were less exposed," reports CNN. "Men exposed to high levels of indoor artificial light also had 2.8-fold higher risk of developing prostate cancer, according to the study." Read more of this story at Slashdot. (Comment on this)
1:10a	Trump Administration Plans To Freeze Obama-Era Fuel Standards The Trump administration plans to freeze Obama-era fuel-efficiency standards starting in 2021, according to a report from The Washington Post. The report says the Trump administration "would go even further by restricting a state's ability to set its own fuel standards, which would be a strike against California and its strict state-specific emissions rules," reports The Verge. From the report: The proposal has been reportedly drafted by the Department of Transportation's National Highway Traffic and Safety Administration, and the plan right now is to freeze standards for cars and light trucks at levels set for the year 2021 and keep them their for five years. The Obama administration's rules, which involved a partnership with California and car makers, set standards at 50 miles per gallon for cars and light trucks by 2025. Obama also, through the Clean Air Act, granted California a waiver to set its own, higher standards. That way, if automobile manufacturers wanted to maintain a presence in the lucrative California market, they'd have to abide by the new rules. The Trump administration now says a separate law overrules that arrangement, The Washington Post reports. Read more of this story at Slashdot. (Comment on this)
