I know it is difficult...waiting each week for the next update of MathNEXUS to learn the latest tibit of news!
For those who cannot wait, I suggest daily visits to the website All the Top Math News.
By design, Alltop is an "online magazine rack" that helps you answer the question, “What’s happening?” in any topic that interests you (e.g. mathematics). The site harvests the headlines of the latest stories from the best sites and blogs that "uncover" mathematical stories. These headlines are displayed, five to a source.” — into individual web pages. Then, Alltop displays the five most recent headlines of the information sources as well as their first paragraph.
Given the daily display of news in mathematics, place your mouse over a "headline" to reveal a verbal "soundbyte" that provides further information. If you are still interested in the headline, click on it as a link to the original source (hopefully still alive).
Be forewarned...Alltop updates the listing every hour...and there is no archive. Thus, you need to check it frequently, as we all know mathematical news is happening quickly and often! (This might be the source of a mathematical problem in itself, determining the rate of change in math-oriented headlines compared to other disciplines).
