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.

Laser-powered invisible images demonstrated: Like disappearing ink, but cooler

I think everyone is aware of the trick with invisible ink. Write your message in lemon juice on paper, and when the juice dries it cannot be seen. But if you heat the paper, the lemon juice reacts with it and turns brown, bringing forth your shining prose for all to read.

That’s so old school—I want laser powered invisible writing (and, no, I am not paid to make sense. Why do you ask?). Since lasers are what make life worthwhile, others evidently felt the same. Lo and behold, there has now been laser-powered invisible writing.

Watching glass glow

To create laser powered invisible writing, we need to delve into how light interacts with matter. Imagine a glass plate. If
