Beat the heat
University of Utah mechanical engineering associate professor Mathieu Francoeur has discovered a way to produce more electricity from heat than thought possible by creating a silicon chip, also known as a 'device,' that converts more thermal radiation into electricity. This could lead to devices such as laptop computers and cellphones with much longer battery life and solar panels that are much more efficient at converting radiant heat to energy. (2019-07-10)

High energy radiotherapy could 'paint' tumours to avoid harming healthy tissue

For patients with esophageal cancer, status of lymph nodes after preoperative therapy determines survival
The status of lymph nodes rather than the status of the primary tumor following preoperative neoadjuvant chemotherapy or chemoradiation therapy is the most important factor that determines whether patients with locally advanced esophageal cancer will survive. The study presented at the AATS 98th Annual Meeting indicates that while preoperative chemotherapy and radiation therapy improve survival of patients with esophageal cancer, patients with malignant lymph nodes following therapy were less likely to survive than patients with no cancer in the lymph nodes. (2018-05-01)

Breathing during radiotherapy - how to hit the treatment target without causing collateral damage
Respiratory movement during radiotherapy makes it difficult to hit the right treatment target and this in turn can lead to an under-dose of radiation to the tumor, or a potentially toxic over-dose to the surrounding healthy tissue. Getting this right is a real challenge for the radiotherapist, but new techniques are helping to deliver the correct dose to the right place. (2012-05-11)

A protein makes the difference
It is well-established knowledge that blood vessels foster the growth of tumors. Preventing the formation of tumors is a standard part of cancer therapy. A study by researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg has discovered a new, surprising role played by blood vessels: under certain conditions they can inhibit tumor growth. (2016-10-18)

Alpha-ray missile therapy: tumor cells attacked from intracellular region
Researchers from Osaka University have innovated a technique of irradiating cancer from within. They tagged α-methyl-L-tyrosine with 211Astatine, an α-emitter, to prepare 211At-AAMT; this radiopharmaceutical was effectively conveyed into cancer cells by the amino acid transporter LAT1. Alpha radiation combines high linear energy transfer with minimal tissue penetration, damaging cancer cells lethally while sparing surrounding normal tissue. This strategy may prove a breakthrough in the management of intractable or advanced cancers. (2021-01-04)

Some Chinese coal ash too radioactive for reuse
Many manufacturers use coal ash from power plants as a low-cost binding agent in concrete and other building materials. But a new study finds that coal ash from high-uranium deposits in China is too radioactive for this use. Some coal ash analyzed in the study contained radiation 43 times higher than the maximum safe limit set for residential building materials by the U.N. Scientific Committee on the Effects of Atomic Radiation. (2017-11-09)

Is breast conserving therapy or mastectomy better for early breast cancer?
Young women with early breast cancer face a difficult choice about whether to opt for a mastectomy or breast conserving therapy (BCT). New research presented at the ESTRO 35 conference has shown young women, who had early stage breast cancer that had not spread to the lymph nodes and who opted for BCT with radiation therapy, had a 13 percent higher risk of developing a local recurrence of their disease over a 20-year period than women who had a mastectomy and no radiation therapy. (2016-04-29)

Ink from ancient Egyptian papyri contains copper
Until recently, it was assumed that the ink used for writing was primarily carbon-based at least until the fourth and fifth centuries AD. But in a new University of Copenhagen study, analyses of 2,000-year-old papyri fragments with X-ray microscopy show that black ink used by Egyptian scribes also contained copper -- an element previously not identified in ancient ink. (2017-11-10)

Using synchrotron radiation at SPring-8 - a large-scale synchrotron radiation facility - Tohoku University, Toshiba Corporation, and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully imaged the magnetization dynamics of a hard disk drive (HDD) write head for the first time, with a precision of one ten-billionth of a second. The method makes possible precise analysis of write head operations, accelerating the development of the next-generation write heads and further increasing HDD capacity. (2021-01-07)

Berry gives boost to cervical cancer therapy
According to the Centers for Disease Control and Prevention, approximately 12,000 women in the United States are diagnosed with cervical cancer each year. One of the most common treatments for cervical cancer is radiation. While radiation therapy destroys cancer cells, it also destroys nearby healthy cells. University of Missouri School of Medicine researchers studied in vitro human cancer cells to show that combining blueberry extract with radiation can increase the treatment's effectiveness.
