When the RF exposure limit of 1.6 watts per kilogram specific absorption rate (SAR) was established in 1996, phones were bigger, bulkier, and carried in holsters outside of clothes and not in pockets, said Marcia Crosse, director of health care at the U.S. Government Accountability Office (GAO) and co-author of the report. … Read more
After a seven-month wait for a bone marrow transplant, 16-year-old Maga Barzalla Sockemtickem endured a lengthy post-transplant treatment at Seattle Children's Hospital. Maga's compromised immune system meant periods of isolation from the outside world. She hadn't seen her cat Merry for more than a month. … Read more
When it comes to certain diseases -- think heart disease, diabetes, and various cancers -- some basic lifestyle changes are the best preventive medicine.
And while most of us know to eat a balanced diet, exercise, and abstain from smoking, it can be far more motivating to make healthy changes if we also know we're prone to certain diseases.
Pew pew! From disc drives to sci-fi shooters, we live in a world full of laser beams. And a special laser made waves in the world of medical research this week. Developed by laser applications researchers from the University of Tennessee's Space Institute, it could one day find use as a weapon against cancer.
Known as a femtosecond laser, the high-speed light pulses at one-quadrillionth of a second; when fine-tuned, the powerful beam can be used by doctors to detect, map, and nullify cancerous tumors. … Read more
Got a new mole? A bad sunburn? A family member with a skin cancer diagnosis?UMSkinCheck, a free new app for iPhone and iPad developed at the University of Michigan, includes a risk calculator that will help you determine your individual risk. If you have any concern at all, it guides you through taking a series of 23 photos that cover your entire body to develop a baseline for future photo comparisons.
"Whole body photography is a well-established resource for following patients at risk for melanoma," Michael Sabel, lead physician in app development and associate professor of surgery … Read more
Modifications to the world's fastest camera are enabling the real-time identification of rare breast cancer cells in blood, with a record low false-positive rate of one cell in a million, according to new research out of UCLA.
"This technology can significantly reduce errors and costs in medical diagnosis," lead author Keisuke Goda, a UCLA program manager in electrical engineering and bioengineering, said in a school news release.
The team's approach could not only pave the way for earlier detection of cancer and monitoring of drug and radiation therapy but also prove useful in urine analysis, water … Read more
Researchers have long used still images of proteins known to be related to recurring cancers in an attempt to understand exactly why these proteins make some chemotherapies fail.
Now, biochemists at Southern Methodist University are using a 3D computer model of the human protein P-glycoprotein -- believed to play a pivotal role in the failure of chemotherapy in many recurring cancers -- to screen more than 8 million potential drug compounds in the hunt for one that will help stop this failure.
"This has been a good proof-of-principle," biochemist John G. Wise said in a school news release. &… Read more
Within a couple years, a single exhale may tell us more about our personal health than merely the current state of our oral hygiene -- and without relying on dogs to sniff out our problems.
The answer lies in a device called the Single Breath Disease Diagnostics Breathalyzer. Back in 2010, Stony Brook University researcher Perena Gouma began testing an earlier iteration in preclinical trials; for use with diabetes patients; now she has developed a sensor that might enable the detection of a range of diseases in a single exhale.
The sensor, which lives in a device about half the … Read more
Are people endangering with their lives, risking cancer, brain tumors, and infertility by talking on their cell phones? A new review by the U.K.'s Health Protection Agency (HPA) says no.
Scientists conducting the review looked at hundreds of studies and assessed all major research into "low-level radio frequency," which they said comes not only from mobile phones but also TV and radio broadcasting, Wi-Fi, and other technologies, and concluded that everyone in the U.K. is exposed to "universal and continuous" radio frequency, according to the BBC.
Despite this constant exposure, the scientists said … Read more
Researchers at Harvard and Children's Hospital Boston have teamed up to create a microfluidic device that harvests and cultures circulating tumor cells (CTCs) from blood samples.
Such cells are shed by primary tumors and circulate in the bloodstream. They sometimes cause metastases, or new recurrences of cancer distant from the original tumor. As such, these cells can shed important light on how far a given cancer has progressed, how that particular patient might respond to drugs and other treatments, and more.
