Did Northwestern University psychology professor push all boundaries when he agreed to organized a sex toy demonstration in class? While the students and administration have defended the after-class live-sex presentation, Prof. John Michael Bailey is facing the wrath of parents.

Evanston, Ill. -- The brain waves of people holding "guilty knowledge" could someday be used to see "inside" the minds of terrorists planning attacks, researchers say.
A Northwestern University study of a group of subjects -- including some "make believe" terrorists with knowledge of an upcoming terrorist "act" -- was able to confirm, through measurements of brain waves, which of the subjects were in possession of "culpable" knowledge of the intended action, a university release said Friday.
The test measured P300 brain activity, electrical patterns in the cortex, to identify which subjects had knowledge of the plan, the release said.
Those patterns occur, researchers said, when meaningful information is presented to a person with "guilty knowledge."

Evanston, Ill. -- U.S. scientists say they've used nanotechnology to develop a PSA detection method for prostate cancer that's 300 times more sensitive than current tests.
Northwestern University researchers said their new system has been able to detect previously undetectable levels of prostate-specific antigen in patients who have undergone radical prostatectomy.
The researchers said the technology -- which uses the nanoparticle-based bio-barcode assay developed at Northwestern -- can easily and quickly detect very low levels of PSA and may enable doctors to diagnose men with prostate cancer recurrence years earlier than currently possible.

Evanston, Ill. -- Researchers at Northwestern University in Illinois say the pen and paper letters written by geniuses like Albert Einstein are very similar to today's e-mails.
The Evanston, Ill., university said in a news release Friday a new study of human behavior at the college found that letters from 16 famed performers, politicians, scientists and writers were written in cycles similar to modern e-mails.
By studying letter-writing patterns of the historical geniuses, which also included Charles Darwin and Sigmund Freud, Northwestern researchers found the great minds did not write letters randomly. Instead, the researchers said, those individuals wrote multiple letters in one sitting with no particular order of important.

Evanston, Ill. -- A new shape-shifting "memory" foam could have widespread use in car engines, inkjet printers and surgical-positioning tools, U.S. scientists said.
The foam developed by researchers at Northwestern University in Illinois and Boise State University in Idaho costs less to produce than similar foams now on the market, Northwestern said in a release Thursday.
The new foam is based on a nickel-manganese-gallium alloy that changes shape when exposed to a magnetic field, the researchers, Northwestern's David Dunand and Boise State's Peter Mullner, said.
"This was such a huge improvement that the foam was tested over and over again to make sure that no experimental mistakes were made," Mullner said.

Evanston, Ill. -- U.S. scientists say they've created a gene therapy system using nanodiamonds to deliver genes to treat such diseases as cancer, diabetes and heart disease.
Northwestern University researchers said their scalable system that can deliver genes to cells both efficiently and safely combines key properties in one approach: enhanced delivery efficiency along with outstanding biocompatibility.
"Finding a more efficient and biocompatible method for gene delivery than is currently available is a major challenge in medicine," Assistant Professor Dean Ho, who led the research, said. "By harnessing the innate advantages of nanodiamonds we now have demonstrated their promise for gene therapy."

Chicago -- U.S. scientists say they've classified the composition profiles of 62 modern sculptures in what may be a way to identify, date and authenticate sculptures.
Researchers from Northwestern University and the Art Institute of Chicago said their accomplishment marks the first comprehensive survey of the alloy composition of a large number of cast bronze sculptures by major European artists from the first half of the 20th century.
The sculptures studied, from the collections of the Art Institute of Chicago and the Philadelphia Museum of Art, included works by Matisse, Picasso, Renoir and Rodin, among other masters.

Evanston, Ill. -- U.S. researchers say they've determined protein damage common in neurodegenerative and age-associated diseases might be treatable if detected early enough.
Northwestern University medical scientists say misfolded and damaged proteins can be detected much earlier than has been thought possible, long before individuals exhibit symptoms. And if intervention occurs early enough damage could be delayed.
The researchers said they studied seven different proteins of the worm C. elegans and found each protein misfolds at the same point: during early adulthood and long before the animal shows any behavioral, or physiological change.

Chicago -- U.S. medical scientists say they have grown immature human egg cells to near maturity in a laboratory.
The Northwestern University Feinberg School of Medicine researchers said their achievement marks the first time anyone has successfully grown a woman's immature egg cells, contained in a tiny sac called a follicle, to a healthy and nearly mature egg in the laboratory. When an egg is fully mature, it is ready to be fertilized.
The scientists said their research, if successful in the next steps, might eventually provide a new fertility option for women whose cancer treatments destroy their ability to reproduce.

Evanston, Ill. -- U.S. scientists have created a method that can direct and separate cancer cells from normal cells, suggesting a new method of treating metastasis.
Northwestern University researchers said the vast majority of cancer deaths are due to metastasis, the spread of cancer cells throughout the body. Scientists are hoping to learn to control the movements of such dangerous cells.
The Northwestern University researchers have demonstrated a simple method that can direct and separate cancer cells from normal cells. Based on that method, they have proposed that cancer cells possibly could be sequestered permanently in a sort of "cancer trap" made of implantable and biodegradable materials.
