While climate change and carbon emissions are widely recognised environmental problems, fewer people are aware of the issue of nitrogen deposition. Today, Plantlife and Plant Link UK have released a new report drawing attention to this issue.What is the source of nitrogen deposition?
Burning fossil fuels and some intensive farming activities lead to the buildup of pools of reactive nitrogen in the atmosphere. This nitrogen is then being deposited onto soils and water, resulting in a range of negative impacts, including declining biodiversity, and acidification of habitats. Humanity’s dependence on fossil fuels has been mirrored by its dependence on nitrogen-based fertilisers to increase crop yields. A coordinated and integrated approach to tackling carbon and nitrogen emissions is needed, as previously highlighted...Read the full article.
My department just did something really cool, and I’d like to tell you about it*.
On a Saturday, my department, along with our campus Center for Innovation in STEM Education, held a family research day.
A room was reserved, and a series of students gave short talks about their research. The talks were designed for their families to learn the purpose of the research that they’re doing. I imagine there were snacks. (I heard that all of the talks were in Spanish.)
Right off the bat, I see some huge benefits.
First, it’s a good experience for students and faculty, to learn more about communicating science with people who aren’t scientists.
Second, it allows faculty mentors and the loved ones of their students to meet. I’ve always enjoyed the brief contact I’ve had with the family of my lab members (usually at graduation or the airport)....Read the full article.
Tolkien knew the value of naming. More than that, he knew the value of understanding and labeling diversity. Tolkien was not satisfied with simply mentioning pipeweed, he needed to mention several varieties (Longbottom Leaf, Old Toby, Southern Star), each with its own properties. I have commented on the subspecies of hobbits that Tolkien named and their characteristics but this urge to name extends to everything from biscuits (...Read the full article.

Rethinking my exams: “Why do we even do exams in college, anyway?”
There’s this company that sells clothes to people who hate going shopping. I’m quite familiar with their service, and it is kind of amazing how they send folks the clothes that they’ll actually like. Here’s a virtual tour of the data science behind their clothes matching algorithms.Read the full article.
