Nearly one in two children with cancer are never diagnosed and may die untreated, according to a new model proposed in a study published in The Lancet Oncology by Zachary Ward and colleagues from Harvard University T.H. Chan School of Public Health.

In fact, the model estimates that there were 397.000 childhood cancer cases globally in 2015, while only 224,000 had been previously recorded as diagnosed that year, leading ultimately the researchers to say that over 43% of childhood cancer cases were undiagnosed. But there was substantial regional variation: it ranges from 3% in both Western Europe (120 undiagnosed cases out of 4,300 total new cases) and North America (300 of 10,900 cases), to 57% (43,000 of 76,000 new cases) in Western Africa. With such path, at current levels of health system performances, If no improvements are made, the study authors estimated that nearly three million out of 6.7 million total cases will be missed between 2015 and 2030.

Projection mapping is one of the most recent visual technologies that so far has been out of reach for consumers. The company Lightform is hoping to change that with its projector-mounted scanner and software. We get our hands on the Lightform device to see how it maps objects and environments in front of it–like a replica movie prop–and go through the software to learn how to create striking augmented visuals on top of the real world.

2017 was the warmest year on record for the global ocean according to an updated ocean analysis from Institute of Atmospheric Physics/Chinese Academy of Science (IAP/CAS). The oceans in the upper 2000 m were 1.51 × 10^22 J warmer than the second warmest year of 2015 and 19.19 × 10^22 J above the 1981–2010 climatological reference period. Owing to its large heat capacity, the ocean accumulates the warming derived from human activities; indeed, more than 90% of Earth’s residual heat related to global warming is absorbed by the ocean. As such, the global ocean heat content record robustly represents the signature of global warming and is impacted less by weather-related noise and climate variability such as El Niño and La Niña events. According to the IAP ocean analysis, the last five years have been the five warmest years in the ocean. Therefore, the long-term warming trend driven by human activities continued unabated.

 

The increase in ocean heat content for 2017 occurred in most regions of the world (Figure). The human greenhouse gas footprint continues to impact the Earth system. Increases in ocean temperature cause ocean volume expansion, which contributes to the global mean sea level rise. The increase in ocean heat of 1.51 × 10^22 J in 2017 resulted in a 1.7 mm sea global level rise. Other consequences include declining ocean oxygen, bleaching of coral reefs, and melting sea ice and ice shelves.
