Older individuals deficient in vitamin D may have double the risk of dementia and Alzheimer's disease, according to a new study published Wednesday. Researchers found that in individuals aged 65 and older, those with "low levels" of vitamin D had a 53 percent increased risk of developing dementia, while those with a "more significant deficiency had a 125 percent increased risk." Both groups were compared to individuals with normal vitamin D levels.

Additionally, the study found that otherwise healthy individuals with lower levels of vitamin D were nearly 70 percent more likely to develop Alzheimer's disease, while those who had a severe vitamin D deficiency were over 120 percent more likely.

That the correlation was so significant came as a surprise to researchers, said Dr. Iain Lang, one of the authors of the study. "We're quite surprised that the results are so big," Lang told BBC Radio 4. "I don't think this is they key to dementia or anything like that, but it's a really important step in finding out what might be going on there."

Vitamin D typically comes from sun exposure or a diet involving oily fish and certain dairy products. Supplements are also available, although Lang said the research was unclear as to whether deliberately increased intake could be beneficial. "What we haven't looked at here is whether, for example, supplementation is something that can... either delay or prevent the onset of dementia," he told the BBC. "We're not at that stage yet, but this is indicative that it's probably time to do that research."

In an article published in its Saturday edition, The New York Times reports that presumptive Democratic nominee Hillary Clinton picked Sen. Tim Kaine as her running mate to attract more white men to her campaign:

Ultimately, Mrs. Clinton, who told PBS that she was "afflicted with the responsibility gene," avoided taking a chance with a less experienced vice-presidential candidate and declined to push the historic nature of her candidacy by adding another woman or a minority to the ticket.

Instead, the campaign, which had become concerned about its deficit with white men, focused on Mr. Kaine and Agriculture Secretary Tom Vilsack, and looked more closely at Gov. John Hickenlooper of Colorado. [The New York Times]

Among white men, Republican Donald Trump leads Clinton 56 to 25 percent, according to a national Quinnipiac survey from the end of June.

Kaine has been described as "boring" following his addition to the ticket, a trope those close to the candidate say is unfair. "I just hate it," Beau Cribbs, Kaine’s former body man, told Buzzfeed News. "I think boring is a code for white and male, frankly." Bonnie Kristian

The Alaska Supreme Court on Friday voted 4-1 to strike down a 2010 state law requiring doctors to notify the parents of girls under the age of 18 if their daughters seek an abortion.

The ruling is a win for Planned Parenthood and Alaskan abortion rights advocates, who made the case that the mandate was a violation of teens' privacy and a danger to girls living in abusive situations. In the majority opinion, Justice Daniel Winfree agreed, writing that the law posed a "discriminatory barrier to those minors seeking to exercise their fundamental privacy right to terminate a pregnancy."

Justice Craig Stowers, the sole dissenter, argued that where a minor is concerned, the state and her parents retain a "legitimate interest" in the situation and, in the parents' case, should be afforded the opportunity to discuss with their child the ramifications of the decision to abort. Parents are required to be notified and give consent where most other significant medical procedures are concerned. Bonnie Kristian

Some 3.7 million Syrian children have been born into war in their native land, but activists are using Pokémon Go to draw international attention to their plight.

The Revolutionary Forces of Syria Media Office (RFS) is sharing images of Syrian kids surrounded by chaos and violence — plus Pokémon. The images allude to the fact that you have to physically go to a new location to capture each monster, urging viewers to likewise come help.

"People on social media talk about Pokémon all the time, so I created these images to draw attention to suffering during the war and what Syrians are really searching for," said Saif Aldeen Tahhan, a graphic designer who has shared mockups of Syria Go, in which users would search for basic necessities like food and shelter instead of fantastic creatures. "I can tell you, the Syrian people are not looking for Pokémon." Bonnie Kristian

Presumptive Democratic nominee Hillary Clinton and her new running mate, Sen. Tim Kaine, held a rally at Florida International University (FIU) in Miami Saturday, marking their official debut as a complete 2016 ticket.

Kaine is perceived as a cautious choice whom Clinton hopes will boost her fortunes among moderate Democrats and independents who might otherwise be attracted to Republican Donald Trump. Florida Democrats traveled from around the state to attend the campaign event, lining up by the hundreds outside the doors hours before it began.

In just the 11th veto of his time in office, President Obama on Friday rejected the "Presidential Allowance Modernization Act of 2016," a bill which would have capped former presidents' expense accounts at $200,000 a year and phased out presidential pensions for former executives who independently make at least $400,000 annually.

White House Press Secretary Josh Earnest said the veto was issued out of concern that the bill would "immediately terminate salaries and all benefits to staffers carrying out the official duties of former Presidents" and require the government to "immediately terminate leases, and remove furniture."

Earnest indicated that Obama, who will himself be an ex-president in six months, would consider signing a revised version of the legislation. Bonnie Kristian

The Islamic State has claimed responsibility for a deadly suicide bombing at a protest in Kabul, the capital of Afghanistan, on Saturday. At least 80 people were killed in the attack and about 230 more were wounded, officials said.

The demonstration was primarily composed of the Shia Hazara minority; ISIS represents an extreme variant of Afghanistan's Sunni majority. The two sects have historically not experienced internecine strife in Afghanistan as they have elsewhere in the Mideast, including Iraq.

The Taliban condemned the incident, calling it an "act of making enmity among Afghan ethnicities" and denying all participation. If ISIS involvement is confirmed, it will be the first time the group has made a major strike in Afghanistan outside Nangarhar province.
