Safety tips when using lithium batteries during your flight.

Follow these safety tips when using lithium batteries during your flight.
  • To prevent overheating, insert lithium-metal batteries correctly, according to the polarity marked on the battery and your electronic device.
  • To prevent heat from building up, do not cover your device’s charger when in use.
  • Do not let lithium batteries come into contact with metal objects, or mix with unpacked batteries, as this may cause them to short-circuit.
  • Do not leave devices plugged into the charger for longer than necessary. Once fully charged, disconnect and turn the charger off.
  • Do not place heavy objects on electronic devices or allow them to get wet.
  • Do not leave lithium-ion batteries unattended while charging.
  • Do not carry damaged or recalled batteries and equipment on-board

Archaeologists discovered 40 ancient shipwrecks at the bottom of the Black Sea.

A group of maritime archeologists studying sea levels in the Black Sea have uncovered over 40 shipwrecks this year as a “complete bonus.”

The Black Sea Maritime Archeology Project has been trawling the seabed to understand how quickly the water level rose after the last Ice Age, 20,000 years ago. But their surveys ended up uncovering dozens of previously unknown wrecks. Many of the discoveries are in excellent condition, thanks to low oxygen levels below 150 meters, which slows decay.

“The wrecks are a complete bonus, but a fascinating discovery, found during the course of our extensive geophysical surveys,” said Jon Adams, a University of Southampton maritime archaeologist and principal investigator of the project, in a statement.

The team took thousands of still photographs of the shipwrecks, and then used photogrammetry, a technique that uses software to calculate the positions of millions of points in space, to build 3D models of the discoveries.
Some of the ships discovered are thousands of years old, dating to the Byzantine empire, while others are from the Ottoman period.
Hulls, masts, tillers, and rudders are all clearly discernible. “Certainly no one has achieved models of this completeness on shipwrecks at these depths,” said Adams.
