Cancer Nanotechnology Research Center Funded

October 8, 2004

The NIH has awarded two universities grants totaling nearly $10 million to establish a multidisciplinary research program in cancer nanotechnology and develop a new class of nanoparticles for molecular and cellular imaging.

One grant will establish a multidisciplinary Bioengineering Research Partnership for scientists from Emory University and the Georgia Institute of Technology. The other grant will be used to develop advanced nanoparticle quantum dot probes for molecular and cellular… read more

Cancer hope for green tea extract

March 15, 2005

Polyphenol EGCG taken from green tea leaves inhibits cancer cell growth, researchers have found.

EGCG binds to a key enzyme–dihydrofolate reductase (DHFR)–that stops the enzyme from triggering the manufacture of new DNA in tumor cells.

It appears to work in the same way as the cancer drug methotrexate, but in practice would probably have fewer side effects. The researchers are using EGCG as the starting point to design… read more

Cancer Drugs Aim at More Targets

June 25, 2004

In a “cluster bomb” approach, drug companies are doing clinical trials of a new generation of cancer drugs that can attack cancer cells on multiple fronts and come in the form of pills, whereas most cancer drugs are delivered intravenously.

But some worry about side effects of the new therapy.

Cancer drug shows promise in reversing Alzheimer’s symptoms in mice

February 12, 2012

Reduction of beta-Amyloid plaque in hippocampus of mice treated with in 14 days

Neuroscientists at Case Western Reserve University School of Medicine have found that bexarotene, a drug currently prescribed to treat cancer, appears to reverse Alzheimer’s symptoms in mice.

The results suggest that bexarotene has a significant potential to help the 5.4 million Americans with the progressive brain disease.

“When used in mice, the drug was successful in removing the buildup of amyloid plaque in the brain… read more

Cancer centers racing to map patients’ genes

April 22, 2013

Human genome sequence

Major academic medical centers in New York and around the country are spending and recruiting heavily in what has become an arms race within the war on cancer.

The investments are based on the belief that the medical establishment is moving toward the routine sequencing of every patient’s genome in the quest for “precision medicine,” a course for prevention and treatment based on the special, even unique characteristics of… read more

Cancer cells found to trigger alternative biochemical pathway that speeds up their metabolism

September 17, 2010

Cancer cells can trigger an alternative biochemical pathway that speeds up their metabolism and diverts the byproducts to construct new cells, says Matthew Vander Heiden, assistant professor of biology and member of the David H. Koch Institute for Integrative Cancer Research at MIT.

The finding, with researchers at Harvard University, could help scientists design drugs that block cancer-cell metabolism, essentially starving them of the materials they need to grow and spread.… read more

Cancer cells dupe the body’s immune system

December 15, 2010

Individual cancer cells send out the same distress signals as wounds, tricking immune cells into helping them grow into tumors, University of Manchester researchers have found. The finding suggests that anti-inflammatory drugs could help to combat or prevent cancer.

Canadian student maps brain to image search

November 29, 2007

A University of Ottawa computer science grad is mapping the way the human brain works to technology that will power a search engine for visual images.

Canadian scientist aims to turn chickens into dinosaurs

August 26, 2009

By flipping certain genetic levers during a chicken embryo’s development, Hans Larsson, the Canada Research Chair in Macro Evolution at Montreal’s McGill University, hopes to create a “chickenosaurus,” demonstrating that birds are direct descendants of dinosaurs.

Canadian Mother Freezes Own Eggs For Infertile Seven Year Old Daughter

July 5, 2007

A Canadian mother has had her eggs frozen for her daughter, who is seven years old and likely to be infertile when she grows up.

Should the girl use one of her mother’s eggs to have a baby later in life, she would effectively give birth to her own half brother or sister.

Canada converting currency from paper to plastic

Canada has just started issuing $100 denomination notes on a polypropylene substrate, and plans to make all of its paper currency plastic within the next two years.

Besides foiling counterfeiters, there are also cost and environmental advantages. The notes are expected to last at least 2.5 times longer, on average, than their paper equivalents. And since fewer replacement notes will be needed over the life of the… read more

Can you teach yourself synaesthesia?

July 13, 2010

A form of synesthesia in which people experience letters or numbers in color may be trainable, University of Amsterdam psychologists have found in an experiment, suggesting that natural synesthesia may develop as a result of childhood experiences as well as genetics.

Can you solve the mystery of the encrypted Gauss payload?

August 15, 2012

There are many remaining mysteries in the Gauss and Flame stories, say antivirus experts Kaspersky in their Secure List blog.

For instance, how do people get infected with the malware? Or, what is the purpose of the uniquely named “Palida Narrow” font that Gauss installs?

Perhaps the most interesting mystery is Gauss’ encrypted warhead. Gauss contains a module named “Godel” that features an encrypted payload. The malware tries… read more

Can you see the emotions I hear? Study says yes

May 18, 2009

Emotions are represented by distinct spatial signatures in the brain that can be detected with fMRI, University of Geneva scientists have found.
