Engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. Many temperature sensors measure thermal radiation coming off the surface of an object. Depth thermography, however, goes beyond the surface and works with a certain class of materials that are partially transparent to infrared radiation. This type of 3D temperature profiling could also be used to measure and map clouds of high temperature gases and liquids. The method may be useful in applications like monitoring semiconductor performance or next-generation nuclear reactors.
Microsoft and tire-manufacturer Bridgestone have come up with a solution to detect tire damage which can’t usually be detected without close, manual inspection. The partnership’s tire damage monitoring system (TDMS) links to Microsoft’s Connected Vehicle Platform (MCVP) to identify tire damage in real-time, and uses algorithms to detect events that affect the tire’s surface. The system also identifies where the damage has happened, which gives road authorities the heads up on potholes and other hazards. And in the future, it could be a useful addition to autonomous vehicle technology, allowing vehicles to share information about nearby road hazards.
Researchers have made a significant breakthrough developing a material that is as strong as the cartilage found in the body and could be used as a replacement after injuries or when people age. The main ingredients of this material include water-absorbing polymers. The hydrogel passed with top marks in the categories of stretching and squishing and showed better performance than other existing hydrogels. It was able to hold up during a test of 100,000 repeated pulls. The new material shows a lot of promise as an option for those experiencing knee replacement surgeries that may one day be able to restore a joint to its full working order without a long recovery period.
A signalling chemical related to women’s fertility called anti-Müllerian hormone (AMH) is incorporated into hair shafts while they are still underneath the skin. AMH is released by eggs in the ovaries, the number of which decline with age. Blood AMH levels broadly correlate with how many eggs a woman has left, and therefore how long it will be before she stops being fertile. In a group of 152 women, hair AMH levels correlated with levels in their blood, and with the number of eggs present in their ovaries as seen by an ultrasound scan. Hair levels of the hormone tracked age better than blood levels, suggesting the hair test may be more accurate.
Maersk has agreed to buy Sweden-based customs broker KGH Customs Services for 2.6 billion Swedish crowns ($281 million), as the container shipping group seeks to expand its end-to-end logistics services. It handles about one in five containers shipped by sea worldwide and is seeking to speed up investments in in-land logistics services. Maersk wants to offer its customers the possibility to book transportation, customs clearance and final delivery at once rather than booking with two or three different suppliers. With the acquisition, Maersk will increase its presence in customs services to 22 European countries from 15 currently.
Berkshire Hathaway said its energy unit will buy Dominion Energy Inc’s natural gas transmission and storage network for $4 billion. The transaction includes more than 7,700 miles (12,390 km) of natural gas transmission lines and 900 billion cubic feet of gas storage. Berkshire Hathaway Energy is buying Dominion Energy Transmission, Questar Pipeline, Carolina Gas Transmission, 50% of the Iroquois Gas Transmission System, and 25% of the Cove Point liquefied natural gas facility in Maryland. The Berkshire unit will also assume $5.7 billion of debt, giving the transaction a $9.7 billion enterprise value. It expects a fourth-quarter closing, pending regulatory approvals.
Scientists in Italy are investigating the mysterious appearance of pink glacial ice in the Alps, caused by algae that accelerate the effects of climate change. Normally ice reflects more than 80% of the sun’s radiation back into the atmosphere, but as algae appear, they darken the ice so that it absorbs the heat and melts more quickly. “We are trying to quantify the effect of other phenomena besides the human one on the overheating of the Earth,” said Di Mauro, noting that the presence of hikers and ski lifts could also have an impact on the algae.
Roshani’s determination to pursue her studies by cycling 24 km every day to and from her school in a has paid off as she has secured 98.75 per cent marks in her Class 10 exams. When asked about her school journey experience, Roshani said, “It was difficult to go to school on a bicycle. Though I didnt count, I cycled for about 60 to 70 days a year to reach the school. My father also took me to school on his motorcycle whenever he had time.” The girl said after returning home, she used to study for seven to eight hours every day.
