Study claims a link between diet sodas and stroke and dementia

Excessive intake of sugar has been linked to a huge variety of health problems, many of them a consequence of the obesity that’s also linked to excessive sugar. That’s led many people to switch to drinks with artificial sweeteners that aren’t metabolized by the body. A new study is now suggesting that these sweeteners are associated with their own health risks, namely stroke and dementia. But the study doesn’t get into causality, and there’s enough oddities in the data to suggest that it’s not time to purge your fridge just yet.

The study, run by a collaboration of Boston-based researchers, relied on a cohort of individuals that had been recruited starting in 1971. On average, every four years since, the

107 cancer papers retracted due to peer review fraud

The journal Tumor Biology is retracting 107 research papers after discovering that the authors faked the peer review process. This isn’t the journal’s first rodeo. Late last year, 58 papers were retracted from seven different journals— 25 came from Tumor Biology for the same reason.

It’s possible to fake peer review because authors are often asked to suggest potential reviewers for their own papers. This is done because research subjects are often blindingly niche; a researcher working in a sub-sub-field may be more aware than the journal editor of who is best-placed to assess the work.

But some journals go further and request, or allow, authors to submit the contact details of these potential reviewers. If the editor isn’t

If you live inland, don’t think sea level rise won’t affect you

There has been a lot of talk about the millions of people worldwide whose homes will be at the mercy of rising sea levels. Within the US, a 1.8-meter rise in the oceans by 2100 could displace as many as 13.1 million people. Worldwide, up to 180 million people could be at risk.

There has been less talk about where exactly those people will go when they leave their homes. Research on climate migration has painted sea level rise as “primarily a coastal issue,” writes Mathew E. Hauer in Nature Climate Change this week. But the inland regions that absorb climate change migrants will need to have sufficient transport, housing, and infrastructure to absorb the migrants.
