I had a dream tonight. I do the final revision of a paper following many months of work and submit it to an internet server. Only 30 minutes later the first science journal agent contacts me offering immediate publication. More and more offers arrive and I finally decide to hand it over to nice publishing company that will pay so much money to continue my research.
I woke up and Continue reading I had a dream tonight

In a previous post we have create calendar snippets in ics format. PHPicalendar is the ultimate solution to stitch these calendar snippets together to a workgroup view.
I am using the built-in RSS feed to be noticed about any forthcoming events that are not sitting in my own calendar.
There is only one drawback: phpicalendar doesn’t offer any possibility to import back any new meeting into Sunbird or Outlook. By using the following patch of events.php it may, however, send you back an .ics file (that can opens Sunbird automatically if configured correctly) by just clicking on any new event.
events.php
|wj_events.txt|
If your calendar ics are really up to date, you may want to change $actual_calname in ical_parser.php to
$actual_calname = getCalendarName($filename) . ‘ (-‘ . round((time() – filemtime($filename) )/100000) . ‘ days old)’;

We should have listened to our parents — but so far I did not see a major adverse potential of cannabis. This might have been wrong having heard last year the terrible story of a friend who lost her son by drug induced psychosis.

Here is a little tale that could have happened every day. An author sends a major paper to a major journal. The major journal has a major editor that asks other major reviewers before writing a major email. Continue reading An editor is one who separates wheat from chaff and then prints the chaff I
Stem cell researchers now believe that the human ES cell line SCNT-hES-1 (you may renember Hwang who claimed having first cloned a human by somatic cell nuclear transfer) is derived by parthogenesis – the result of a dividing human oocyte.
They test the origin of the Hwang cells by genome-wide SNP analysis as the initial DNA fingerprint was doubtful Continue reading Human parthogenesis
A new paper in Transplantation takes up an old question – can you passively transfer asthma or allergy? It seems so – the current study reports in 5 of 42 patients elevated IgE plus allergy symptoms. This is in line with earlier reports. Sorry to say — you can get allergy also by bone marrow transplantation.

A total of 16 nonallergic recipients with allergic donors were reported to develop allergic disease posttransplant, however, conclusive information was available for only 5 cases. Allergic disease was reported to abate in 3 allergic recipients with nonallergic donors, however, conclusive information was available for only 2 cases. Problems in interpreting the reports include incomplete data on allergic disease in the donor or recipient pretransplant, not knowing the denominator, and the lack of controls. In summary, review of the literature generates the hypothesis that allergic disease is transferable
