+ - Technique to turn all blood into type 0

Submitted by davidwr
davidwr (791652) writes "Is this the end of type-O blood shortages? In an article published in the journal Nature Biotechnology, researchers figured out how to make bacterial enzymes turn type-A, -B, and -AB blood into type O blood, or "universal red blood cells." From the abstract:

The enzymatic conversion processes we describe hold promise for achieving the goal of producing universal RBCs, which would improve the blood supply while enhancing the safety of clinical transfusions.

Journal: April Fool's Submissions Overboard and Underfunny 2

Journal by evought

I agree with some of the comments and submissions I have seen today that the yearly stupidity on Slashdot is just plain dumb. Unfortunately, these comments are drowned out. One or two good hoaxes would have made my day. ("Google Paper" was actually quite good). A score of idiotic and unbelievable posts just ruins the site and real news is buried. Having looked through the Firehose at several points today, there have been several serious submissions that have been voted up but have never made

Anonymous Coward writes "My domain name is periodically being stolen by spammers; they forge outgoing mail using my poor innocent domain name. First, I'd like to plead with mail server administrators out there: please REJECT spam and undeliverable mail. If you reject instead of bouncing then legitimate mail senders will still know there is a problem. Second, do you have any tips for dealing with a flood of spam bounces? Exim is pitching the bounces pretty quickly, but my server is still getting overwhelmed."

Submitted by Anonymous Coward
An anonymous reader writes "There's a lot going on in the file-sharing world, and P2P news site Slyck.com has an interesting comparison of two methods of online distribution: Usenet (the newsgroups) and BitTorrent. Slyck concludes that because of its fast speed, large selection and relatively anonymity, Usenet beats out BitTorrent."

+ - Researchers Find Bias in Nutrition Studies

Submitted by Optic7
Optic7 (688717) writes "NPR reports that a new study by Harvard and the Center for Science in the Public Interest found that nutrition studies funded by food companies are almost eight times more likely to reach a conclusion beneficial to the food companies than similar, independently funded studies. New Scientist has also done a story on this, if you prefer to read instead of listen to the NPR story."

Submitted by kpw10
kpw10 (750127) writes "Dr. Jeff Masters from Wunderground has a great summary of this year's rather abnormal weather (his blog is the best source on the net for in-depth weather analysis). The post discusses some of the cyclical climate forces at work this year as well as compares this year's record temperatures to records from the past — there are some interesting differences particularly in the extent of northern hemisphere seeing record highs this year. From the article: "December's weather in the Northeast U.S. may have been a case of the weather dice coming up thirteen — weather not seen on the planet since before the Ice Age began, 118,000 years ago. The weather dice will start rolling an increasing number of thirteens in coming years, and an ice-free Arctic Ocean in summertime by 2040 is a very real possibility...""

+ - What does your dead man's switch do?

Submitted by
LqdEngineer
LqdEngineer writes "How many of the Slashdot crowd use or have used a Dead Man's Switch designed to perform some action if you don't check in for a certain amount of time? Recently, I decided to put one together using MySQL and some Cron jobs, but I wanted to see what others have their Switches set up to do in the event you fail to check in. E-mails to loved ones? Send encryption keys to friends/family? Hate mail to your boss? Has anyone ever been on the receiving end of a Dead Man's e-mail? I can't even imagine how creepy that would feel."

+ - college math classes forcing windows on students?

Submitted by
OiToTheWorld
OiToTheWorld writes "I recently started classes again after winter break. On arriving in my math class, we were told that we had to use the MYMATHLAB software to turn in homework online. The catch is that this software/membership that I paid for along with my textbook will ONLY work on Internet Explorer and apparently shows no indication of changing this. Having asked the teacher if I could turn in the assignments on paper because my linux computer could not run internet explorer, I was told no and that I essentially needed to buy a new operating system in order to pass the class.

My questions are these: Is there a workaround method i can use to do my assignments? why would the company that sells the software do this? Has anyone else encountered similar problems with other software?"

+ - Make Artificial Volcanos vs Global Warming? ideas?

Submitted by Anonymous Coward
An anonymous reader writes "So, volcanos like Pinitubo and St Helens are thought to have lowered global temperatures. Global warming, is widely publicized as a Bad Thing (dont want that debate here). So, assuming for the moment both are the case:

a) Any ideas on how we might efficiently mimic a volcano and get the same particles or gases into the upper atmosphere?

Should we build the worlds biggest shotgun and point it at the sky? Should we nuke some small, inoffensive country for the nuclear winter effects? (j/k) Should we just try to create a ring of thermal updrafts to make a "chimney" tube, and then inside that tube, try to have some kind of super-thermal updraft? Even if we have to find natural geothermal to power it (ie: bulldoze off the top of a volcano, to expose the hot part), would that actually reach the upper atmosphere? Should we be like springfield and build a protective layer of industrial pollution? Is it cheaper and easier to find a near-earth asteroid, like the one due in the 2030s, and convince it to crash into the earth? (preferably somewhere not in my backyard)

for bonus points:

b) does anyone know the approximate scale of gases/particles that a volcano like Pinitubu releases, compared to some kind of estimate of the industrial release of pollution or CO2, or even compared to cows "releasing" methane?"

+ - Sex lowers stress levels

Submitted by Ice Wewe
Ice Wewe (936718) writes "BBCNews has an article on how having penetrative intercourse can help with public speaking.

"New Scientist magazine reports that Stuart Brody, a psychologist at the University of Paisley, found having sex can help keep stress at bay. However, only penetrative intercourse did the trick — other forms of sex had no impact on stress levels at all.

... Volunteers who had had penetrative intercourse were found to be the least stressed, and their blood pressure returned to normal faster than those who had engaged in other forms of sexual activity such as masturbation. "
