Another mention of Meller group

2

The November issue of Photonics Spectra has an article on new DNA
sequencing technologies.  Amit Meller’s group and their work with
nanopores is mentioned.  Unfortunately, only an abstract is
available online, but you can apply for a free subscription to the
print magazine at the website.

Wiki of MIT and Harvard biologists

ø

MIT and Harvard scientists have collaborated with labs from other
universities on a wiki named OpenWetWare.   It has a listing
of lab pages and a tools section, as well as a FAQ and etiquette
guidelines.  It’s described as a place for scientists to organize
information.  (Source: Nature)

Update on Zvonimir Dogic’s lab

The PhysicsWeb article “Doing Physics with Bacteria” highlights the
work of Rowland’s Zvonimir Dogic, who studies phase transitions of
bacterial flagellar filaments in their latest paper.

Little known archive of psychology papers and instruments

This is maintained in a basement owned by the University of
Akron.  It is an archive of American psychology and includes
papers of over seven hundred psychologists and many instruments from
famous experiments such as Milgram’s.

On false research findings

ø

From PLoS Medicine: “There is increasing concern that most current
published research findings are false. The probability that a research
claim is true may depend on study power and bias, the number of other
studies on the same question, and, importantly, the ratio of true to no
relationships among the relationships probed in each scientific field.
In this framework, a research finding is less likely to be true when
the studies conducted in a field are smaller; when effect sizes are
smaller; when there is a greater number and lesser preselection of
tested relationships; where there is greater flexibility in designs,
definitions, outcomes, and analytical modes; when there is greater
financial and other interest and prejudice; and when more teams are
involved in a scientific field in chase of statistical significance.
Simulations show that for most study designs and settings, it is more
likely for a research claim to be false than true. Moreover, for many
current scientific fields, claimed research findings may often be
simply accurate measures of the prevailing bias.” (Sources: Daypop,
