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)

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)

Russian chemists developed a way to synthesize drugs from renewable precursors
The scientists of RUDN University together with their Russian colleagues have developed a new approach to the synthesis of benzofurans from cheap raw materials.

The results of the work were described in the article published in Tetrahedron. (2017-11-14)

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)

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)

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.

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.
