Cancer Will Kill Nearly 10 Million People This Year, Report Estimates

(CNN) — The number of people around the world who have cancer is “rapidly growing,” with 18.1 million new cases and 9.6 million deaths in 2018 alone, researchers estimate in a new report. By the end of the century, cancer will be the No. 1 killer globally and the single biggest barrier to increasing our life expectancy, according to the report, released Wednesday by the World’s Health Organization’s International Agency for Research on Cancer. Cancer by the numbers The researchers used data from 185 countries, looking at all the places in the body cancer can occur and taking a deeper look at 36 types. Based on this data, one in five men and one in six women will develop cancer during their lifetime, the researchers estimate. One in eight men and one in 11 women will die from the disease. The number of cancer cases is increasing for a number of reasons, the report says: The global population is growing, and more people means more cancer. The population is also aging, and cancer risks grow as you age. The numbers also look worse because in many countries, stroke and heart disease deaths are declining. Cancer varies by region The likelihood that you’ll get cancer or die from it depends, in part, on where you live. Nearly half of the new cancer cases and more than half the cancer deaths worldwide were in Asia, home to 60% of the world’s population. The Americas, however, have their own serious problems with the disease, with 21% of cancer...

Herein, we report the deposition of CuO and Au nanodomains on Cu2O cubes to form dual surface heterostructures (HCs) to improve photocatalytic activity and stability. The apparent quantum efficiency of Au/CuO/Cu2O HCs was ca. 123 times that of pristine Cu2O. In addition, the Au/CuO/Cu2O HCs maintained nearly 80% of its original activity after eight cycles i...

In this study, 2D-2D TiO2 nanosheet/layered WS2 (TNS/WS2) heterojunctions were prepared via a hydrothermal method. The structure and morphology of the photocatalysts were systematically characterized. Layered WS2 (∼4 layers) was wrapped on the surface of TiO2 nanosheets with a plate-to-plate stacked structure and connected with each other by W=O bonds. The as-prepared TNS/WS2 heterojunctions showed higher photocatalytic activity for the degradation of RhB under visible-light irradiation, than pristine TiO2 nanosheets and layered WS2. The improvement of photocatalytic activity was primarily attributed to enhanced charge...

In this study, we found that the catalytic water oxidation activity on amorphous iron-based oxide/hydroxide (FeOx) can be decreased by an order of magnitude after the dehydration process at room temperature. Thermogravimetric analysis, XRD and Raman results indicated that the dehydration process of FeOx at room temperature causes the almost completely loss of water molecule with no bulk structural changes. Based on this finding, we prepared hydrated ultrasmall (ca. 2.2 nm) FeOx nanoparticles of amorphous feature, which turns out to be extremely active as WOC with turnover frequency (TOF) up to 9.3 s−1 in the photocat...
