Melanoma

With around 200,000 new cases worldwide of malignant melanoma, the most virulent form of skin cancer, reported in 2008 according to Cancer Research UK statistics, limiting exposure to the sun is vitally important. But keeping track of our exposure, particularly on cloudy days, can be a difficult exercise. New technology developed at the University of Strathclyde makes things easier by providing a visual warning of when to seek some shade or slap on some more sunscreen.  Read More

Despite years of health promotion campaigns advising us about the dangers of skin cancer, the incidence of the most dangerous type - melanoma - has been steadily rising since the 1970s with around 130,000 cases now diagnosed globally each year according to the World Health Organization. Even if we no longer spend hours sunning ourselves on the beach, extended time outdoors playing sport or socializing can still put us at risk of this deadly cancer. MelApp is an iPhone app designed help detect melanoma at an early - and likely curable - stage using mathematical algorithms and image based pattern recognition technology.  Read More

Solariums significantly increase the risk of skin cancer

Ever since the 1920s, getting a tan has been highly fashionable in many Western cultures. Despite the growing mountain of evidence regarding the dangers, many (mainly young) people continue to use solariums as a way to attain what is often seen as a “healthy tan.” However, the evidence just keeps piling up with two new studies out of Australia, home of the “bronzed Aussie,” showing that using a solarium significantly raises ones chances of being diagnosed with skin cancer and that the risks increase as the age of solarium use decreases.  Read More

The 3D high clarity image of melanoma produced using the new imaging technique

Even though melanoma is one of the less common types of skin cancer, it accounts for the majority of skin cancer deaths – around 75 percent. The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence. So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining “clean margins” all around the tumor. So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery – until now.  Read More

Bioluminescence imaging (BLI) of T cell trafficking in live mice used in the study

One of the main problems with cancer cells is that the body's immune system generally doesn’t recognize them as enemies. By using a crippled HIV-like virus as a vehicle to arm lymphocytes with T-cell receptors, researchers have been able to genetically engineer a well-armed battalion of tumor-seeking immune system cells. By also inserting a reporter gene, which glows “hot” during positron emission tomography (PET) scanning, the researchers were able to watch in real time as these "special forces" traveled throughout the body to locate and attack dangerous melanomas.  Read More

Johns Hopkins researchers are testing an infrared scanning system to detect melanoma (Imag...

Although melanoma is one of the less common types of skin cancer, it is responsible for the majority (around 75 percent) of skin cancer related deaths. Part of the problem is that current diagnoses rely on subjective clues such as size, shape and coloring of a mole. With the aim of providing an objective measurement as to whether a lesion may be malignant, researchers at John Hopkins University have developed a prototype non-invasive infrared scanning system that works by looking for the tiny temperature difference between healthy tissue and a growing tumor.  Read More

March 24, 2009 A minimally invasive therapy that could help fight cancer may be on its way with the development of the first hollow gold nanospheres that actively search for and burn tumors. Researchers believe the new technique could prove particularly effective against malignant Melanoma, a deadly form of skin cancer responsible for around 48,000 deaths worldwide each year... and numbers are growing.  Read More

The Self-Energy Converting Sunglasses (SIG)

They may or may not set the fashion world alight, but these solar power-generating sunglasses designed by Hyun-Joong Kim and Kwang-Seok Jeong deserve top marks for ingenuity. As well as providing UV protection from the sun, the concept employs dye solar cells integrated into the lenses to power your portable electronic devices.  Read More

The 2007 Lemelson-MIT Student Prize

February 15, 2007 If there’s an absolutely golden imprimatur for the person-most-likely-to-succeed, it’s the Lemelson-MIT Student Prize. Jerome H. Lemelson, one of the world's most prolific inventors, and his wife Dorothy founded the Lemelson-MIT Program funded via his own private philanthropic Lemelson Foundation, the Student Prize recognizes outstanding inventors, encourages sustainable new solutions to real-world problems, and enables and inspires young people to pursue creative lives and careers through invention. Given that MIT attracts the very brightest students to begin with, the winner is usually a stellar high achiever and this year’s winner is already that. 2007 winner Nathan Ball's inventions include the Atlas Rope Ascender (see separate story) and a needle-free injection technology that will enable greater efficiencies in mass inoculations, both capable of saving many lives and both with many commercial applications. Last year’s winner Carl Dietrich is the CEO and CTO of his own flying car company Terrafugia. We’ve also written about Saul Griffith, the 2004 winner. All the winners and their exploits in this article.  Read More

New insight into skin-tanning process suggests novel way of preventing skin cancer

October 9, 2006 Though synthetic images and contrived looks help to shape our ideas of what’s attractive and what’s passe, we suspect the suntanned look triggers recognition of a healthy, robust outdoorsy person and no matter what shape the Ozone Layer is in, the bronzed look is still likely to be fashionable for a long time yet. Which makes the following great news for the sun worshippers of the world. Findings from a study led by researchers at Dana-Farber Cancer Institute and Children's Hospital in Boston have rewritten science's understanding of the process of skin tanning – an insight that has enabled them to develop a promising way of protecting fair-skinned people from skin cancer caused by exposure to sunlight.  Read More
