Vitamin D casts cancer prevention in new light

April 29, 2007

Cancers in rich countries isn’t caused mainly by pollutants but by a vitamin D deficiency, research suggests.

Researchers are linking low vitamin D status to a host of other serious ailments, including multiple sclerosis, juvenile diabetes, influenza, osteoporosis and bone fractures among the elderly.

A four-year clinical trial involving 1,200 women found those taking the vitamin had about a 60-per-cent reduction in cancer incidence, compared with those who… read more

Vitamin D a key player in overall health of several body organs

October 10, 2008

Anthony Norman, a UC Riverside expert on vitamin D, has found 36 organ tissues in the body whose cells respond biologically to vitamin D, inciuding bone marrow, breast, colon, intestine, kidney, lung, prostate, retina, skin, stomach and the uterus; deficiency of vitamin D can impact all of them, and also cause muscle strength decrease, high risk for falls, and increased risk for colorectal, prostate and breast and other major cancers.… read more

Vitamin C lowers levels of inflammation biomarker considered predictor of heart disease

November 14, 2008

A new study led by researchers at the University of California, Berkeley adds to the evidence that vitamin C supplements can lower concentrations of C-reactive protein (CRP), a biomarker for elevated risk of cardiovascular problems and diabetes.

However, they also found that treatment with vitamin C is ineffective in persons whose levels of CRP are less than 1 milligram per liter. The researchers also said that for people with… read more

Vitamin C jabs may combat cancer

August 5, 2008

National Institute of Diabetes and Digestive and Kidney Diseases researchers injected immune-deficient mice with cells from three aggressive human cancers — ovarian and pancreatic tumors, plus a form of brain cancer called glioblastoma — and found that vitamin C injections slowed tumour growth by up to 53%.

By injecting into the bloodstream, it is possible to get much larger amounts of the vitamin to a tumor than is possible… read more

Visualizing how TMS affects groups of neurons in real time

September 17, 2014

Spatiotemporal activity patterns induced by a single TMS pulse (left) and 10 Hz TMS (right) over 50 milliseconds (credit: Vladislav Kozyre et al./

German neuroscientists have developed a method for recording the effects of transcranial magnetic stimulation (TMS) on animals in real time, using voltage-sensitive dyes, which emit fluorescent light signals that indicate which groups of neurons are activated or inhibited.

Using fMRI is too slow to show real-time effects, and with rapid measurement methods like EEG and MEG, the TMS magnetic field generates artifacts.

So RUB researchers headed by… read more

Visualizing data in the AlloSphere

April 16, 2009

TED has just released a video with JoAnn Kuchera-Morin, who demos the AlloSphere, an entirely new way to see and interpret scientific data, in full color and surround sound inside a massive metal sphere. Dive into the brain, feel electron spin, hear the music of the elements …

Composer JoAnn Kuchera-Morin is the director of the Center for Research in Electronic Art Technology (CREATE) at… read more

Visualising invisibility

August 1, 2006

A new study published in the New Journal of Physics describes the physics of several theoretical devices that could create invisibility.

The ideas in the paper are based around devices that will bend light or radio waves around a hole inside a device. Any object placed inside the hole will become invisible.

There are advances being made in metamaterials that mean the first devices will probably be used… read more

Visual Strategies

visual-strategies-book

A new book, Visual Strategies, by Felice C. Frankel and Angela H. DePace is “a guide to graphics for scientists and engineers, but it will be useful for anyone who wants to make clear presentations of data of any kind, The New York Times reports.

The book offers general guidelines, with illustrative graphics, and many real-life case studies. The authors show how they… read more

Visual computing still decades from computational apex

With 120 million monochrome and 5 million color receptors, the eye and brain are able to do what even our most advanced cameras are unable to, according to computer graphics pioneer Tim Sweeney of Epic Games.

With a resolution of about 30 megapixels, the human eye is able to gather information at about 72 frames per second, which explains why many gamers debate the need for frame rates higher than… read more

Visual Brain Areas Assist Inflamed Optic Nerves

October 6, 2004

Researchers using functional magnetic resonance imaging of the brain found that visual areas of the cortex could adapt to altered input coming from an inflamed optic nerve.

Areas of the brain normally associated with more specialized higher visual processing reorganized themselves in response to the faulty visual information transmitted by the nerve. The techniques used in this study could also be applied to other conditions such as stroke in… read more

VISTA gigapixel mosaic of the central parts of the Milky Way

November 7, 2012

This striking view of the central parts of the Milky Way was obtained with the VISTA survey telescope at the European Southern Observatory (ESO)’s Paranal Observatory in Chile. This huge picture is 108,500 by 81,500 pixels — nearly nine billion pixels. It was created by combining thousands of individual images from VISTA, taken through three different infrared filters, into a single monumental mosaic. VISTA has a… read more

Visionary Kurzweil Touts Technologies Of Tomorrow

November 17, 2005

Computer visionary Ray Kurzweil examined the effects of accelerating growth of technologies on the present and future of human technological innovation during a speech at the ninth annual CRN Industry Hall of Fame, held Tuesday in Santa Clara, Calif.

The bulk of human intelligence is pattern recognition, which Kurzweil said is the quintessential example of a self-organizing system. This will be instrumental in the development of future Web-based applications,… read more

Visionary device gives hope 20-year high-tech project aims to restore sight, boost quality of life

March 11, 2008

The Boston Retinal Implant Project is developing a retinal implant that uses special glasses wired with a battery-powered camera and transmitter that sends images to a chip implanted behind the retina.

First human surgeries are expected to take place in the next few years.
