In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of Tyrannosaurus rex. A 1/40th-scale model is brought to the classroom to introduce the students to the quandary: given that the forelimbs of T. rex were too short to reach its mouth, what function did the forelimbs serve? This issue crosses several scientific disciplines including paleontology, ecology, and physics, making it a great starting point for thinking “outside the box..." Lipkin and Carpenter have suggested that the forelimbs were used to hold a struggling victim (which had not been dispatched with the first bite) while the final, lethal bite was applied. If that is the case, then the forelimbs must be capable of large angular accelerations α in order to grab the animal attempting to escape. The concepts of the typical first-year physics course are sufficient to test this hypothesis... Naturally, student love solving any problem related to Tyrannosaurus rex.
"For many a female octopus, laying eggs marks the beginning of the end (pdf, 1.11MB). She needs to cover them and defend them against would-be predators. She needs to gently waft currents over them so they get a constant supply of fresh, oxygenated water. And she does this continuously, never leaving and never eating. (via)."
"... a series of curated, open access books about life — with life understood both philosophically and biologically — which provide a bridge between the humanities and the sciences." Although they offer "frozen PDFs," these books—on topics like biosemiotics, animal experience, and air—are curated collections of links to open access science articles, reviews, interviews, podcasts, sometimes with embedded sounds and videos. They have ISBN numbers and editors vetted by the Open Humanities Press, which is generally a gold mine of interesting books and journals. They feel perfectly at home on the open internet, evoking hope and nostalgia for a flourishing academic world wide web, without paywalls and login screens. [more inside]
Prestige scientific journals are bad for science, and we should avoid them. "Just as Wall Street needs to break the hold of bonus culture, so science must break the tyranny of the luxury journals." So argues Nobel laureate Randy Schekman, urging scholars to shift their work to open source journals. [more inside]
"People are denied access to research hidden behind paywalls every day. This problem is invisible, but it slows innovation, kills curiosity and harms patients. This is an indictment of the current system. Open Access has given us the solution to this problem by allowing everyone to read and re-use research. We created the Open Access Button to track the impact of paywalls and help you get access to the research you need. By using the button you’ll help show the impact of this problem, drive awareness of the issue, and help change the system. Furthermore, the Open Access Button has several ways of helping you get access to the research you need right now." [more inside]
On 4 July, good news arrived in the inbox of Ocorrafoo Cobange, a biologist at the Wassee Institute of Medicine in Asmara. It was the official letter of acceptance for a paper he had submitted 2 months earlier to the Journal of Natural Pharmaceuticals, describing the anticancer properties of a chemical that Cobange had extracted from a lichen.
"In a long-awaited leap forward for open access, the US government said today that publications from taxpayer-funded research should be made free to read after a year’s delay – expanding a policy which until now has only applied to biomedical science." [more inside]
The Cost of Knowledge lets scientists register their support for a boycott of all Elsevier journals for their support of SOPA, PIPA (tag) and the Research Works Act (previously, WP, MLA, UK, Oz, etc.). It appears the boycott was inspired by Field's medalist Tim Gowers' recent comments describing his personal boycott of Elsevier journals. [more inside]
"The Architecture of Access to Scientific Information: Just How Badly We Have Messed This Up" Lawrence Lessig speaking at CERN on April 18, 2011. Long (~50 min), but wonderful and totally worth it (and the second half is about Youtube and remix culture).
Libraries and commercial publishers have struggled with each other over the skyrocketing costs of academic journals for years. As costs have increased more rapidly than library budgets, the libraries have had to cut journal subscriptions and other acquisitions. The recent recession has necessitated further cuts. Against this backdrop, Nature Publishing Group told the University of California that next year subscription prices would increase 400 percent, with the average annual cost of a journal increasing to $17,479. UC Libraries fought back with a combative letter to UC faculty suggesting that faculty should consider boycotting the journals, and cease submitting or reviewing articles for these journals. NPG responds, saying that UC currently pays unfairly low rates, and that "individual scientists, both within and outside of California are already suffering as a result of [UC]'s unwarranted actions."
These findings are especially taters in the context of the what cancer taters further future investigation into this field.

Harvard's Faculty of Arts & Sciences voted unanimously last week to mandate "Open Access" to published articles - a first at a U.S. university, though the dean will apparently grant a waiver to anyone who wants to opt out. More to follow? Peter Suber's Open Access News is tracking reactions. [more inside]
