Caprica prequel to Battlestar Galactica premieres Friday

January 21, 2009

Entangled in the burgeoning technology of artificial intelligence and robotics that will eventually lead to the creation of the Cylons 58 years later in Battlestar Galactica, two rival families go toe-to-toe, blending action with corporate conspiracy and sexual politics.

That’s the premise of the new Caprica Syfy Channel series, which premieres Friday, Jan. 22 at 9/8C on SyFy. Pilot here.

Capping Two-faced ‘Janus’ Nanoparticle Gives Engineers Complete Control

August 14, 2009

Duke University engineers have for the first time achieved optical and magnetic control over all the degrees of an nanoparticle’s motion, opening up broad possibilities for using “dot-Janus” particles as building blocks for applications such as electronic paper, self-propelling micromachines, assembly of nanostructures, and controlling the behavior of cells by manipulating dot-Janus particles attached to cell surfaces.

Canyon or Mirage?

March 5, 2004

The difference in availability of information and communication technologies (between rich and poorer countries, known as the “digital divide,” has concerned policymakers, academics, and non-governmental organizations. But two economists at the World Bank have found that current trends suggest the divide is actually shrinking, not growing.

Cantilever bends repeatedly under light exposure for continuous energy generation

With the goal of enabling small electronic devices to harvest their own energy, Louisiana Tech University researchers have designed a device that can convert light and thermal energy into electricity.

When exposed to visible light and/or heat (infrared) radiation, the 20-mm-long carbon-nanotube-film-based cantilever bends back and forth repeatedly, as long as the light and/or heat remains on.

In their experiments, they demonstrated that the device could generate 2.1… read more

The adjustable-height “sit/stand” desk, such as the GeekDesk, offers a potentially healthier way to work.

Canon Fuel Cell DSLR Update

August 12, 2008

Canon has filed a patent application claiming a method for powering a digital SLR camera and external components, such as lenses and hotshoe flash.

Cannabinoid receptors protect against aging

July 13, 2011

Researchers from the Universities of Bonn and Mainz have discovered a previously unknown function of the cannabinoid-1 receptor (CB1): it can protect against aging processes.

Cannabinoids, such as THC (the active agent in Cannabis sativa) and endocannabinoids, and those formed by the body bind to the CB1 receptors. The existence of this receptor is also the reason for the intoxicating effect of hashish… read more

Cancer’s origins revealed

Researchers discover the genetic imprints and signatures left by DNA-damaging processes that lead to cancer
September 5, 2013

cancer_signature

Researchers at Wellcome Trust Sanger Institute have provided the first comprehensive compendium of mutational processes that drive tumor development. Together, these mutational processes explain most mutations found in 30 of the most common cancer types. This new understanding of cancer development could help to treat and prevent a wide-range of cancers.

Each mutational process leaves a particular pattern of mutations, an imprint or signature, in… read more

Cancers inhibited by embryonic stem cell protein

March 5, 2008

Northwestern University researchers have discovered that a protein, Lefty, produced by human embryonic stem cells (hESCs) can inhibit the growth and spread of breast cancer and malignant melanoma.

Similarities between stem cells and tumors–both are self-renewing and have the capacity to give rise to different cells types–previously led the researchers to find the protein Nodal, which facilitates cell growth, and suggested that stem cells must have a way to… read more

Cancer: Is a cure within reach?

January 2, 2002

The field of cancer is undergoing a sea change, thanks to the genetics revolution that has uncovered many of the defects responsible for causing the disease. Using the latest molecular biology techniques to home in on cancer’s genetic roots, doctors are starting to halt precancerous growths before tumors ever develop and to target cancers that have already started to grow with a precision unimaginable just a decade ago.Some of the… read more

Cancer, Carefully Illuminated

December 11, 2008

Researchers at the National Cancer Institute (NCI) and the University of Tokyo have developed a new imaging probe that specifically targets and illuminates tumors, even at the submillimeter scale.

Cancer Therapy Without Side Effects Nearing Trials

April 15, 2008

A promising new cancer treatment that may one day replace radiation and chemotherapy is edging closer to human trials.

Kanzius RF therapy attaches gold or carbon nanoparticles to cancer cells identified by recognition molecules, and then “cooks” tumors inside the body with harmless radio waves.

Cancer survival rates could improve soon, thanks to whole-genome sequencing: JAMA editorial

April 20, 2011

Two studies published in the April 20 issue of the Journal of the American Medical Association (JAMA) suggest that cancer survival rates could improve soon with whole-genome sequencing,  according to an editorial by Boris Pasche, M.D., deputy director of the University of Alabama at Birmingham Comprehensive Cancer Center and professor of medicine.

Whole-genome sequencing, which maps a person’s DNA and analyzes… read more

Cancer risk linked to DNA ‘wormholes’

February 25, 2015

dna spiral

Single-letter genetic variations within parts of the genome once dismissed as “junk DNA” can increase cancer risk through remote effects on far-off genes, new research by scientists at The Institute of Cancer Research, London shows.

The researchers found that DNA sequences within “gene deserts” — so called because they are completely devoid of genes — can regulate gene activity elsewhere by forming DNA loops across… read more
