New collaborative research published in the journal Nature Communications by scientists from Japan, Russia and the US contains the genetic analysis on a species of African midge, which can survive a wide array of extreme conditions including large variations in temperature, extreme drought and even airless vacuums such as space. The team successfully deciphered the genetic mechanism that makes the midge invulnerable to these harsh conditions. Prof. Noriyuki Satoh and Dr. Takeshi Kawashima of Prof. Satoh’s Marine Genomics Unit, as well as Prof. Alexander Mikeyhev of the Ecology and Evolution Unit, and Mr. Manabu Fujie and Dr. Ryo Koyanagi of the DNA Sequencing Section at the Okinawa Institute of Science and Technology Graduate University have contributed to the collaboration.
The midge, Polypedilum vanderplanki, is capable of anhydrobiosis, a unique state that allows an organism to survive even after losing 97% of its body water. Anhydrobiotic organisms are also able to survive other severe conditions such as extreme temperatures ranging from 90°C to-270°C, vacuums and high doses of radiation; all of which would be lethal to most other life forms.

Scientists have found a new chemical process to turn a stinky, toxic gas into a clean-burning fuel.
The process, detailed recently in the American Chemical Society journal ACS Sustainable Chemical Engineering, turns hydrogen sulfide —more commonly called “sewer gas”—into hydrogen fuel. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.
The process detailed in this study uses relatively little energy and a relatively cheap material—the chemical iron sulfide with a trace amount of molybdenum as an additive.
Researchers on quest to understand how different sexes first evolved.
For 30 years, University of Tokyo Associate Professor Hisayoshi Nozaki has traveled an hour west of Tokyo to visit the Sagami River and collect algal samples to understand how living things evolved different sexes. Through new analysis of samples collected in 2007 and 2013 from dam lakes along the river, Lake Sagami and Lake Tsukui, researchers identified a species of freshwater algae that evolved three different sexes, all of which can breed in pairs with each other.
This phenomenon of three sexes is slightly different from hermaphroditism. In species that normally have two sexes, a hermaphroditic individual who can produce both the male and female sex cells usually exists due to unusual gene expression. Many plants and some invertebrate species have three sexes due to normal gene expression, but this is the first time a species of algae or fungi has been identified with three sexes.
Forward-looking: A team of researchers have devised a new method for protecting SSDs from ransomware attacks. It can detect ransomware, stop it in its tracks, and even recover stolen data in a matter of seconds. The cost should only be a minor increase in the SSD’s latency.
The Register spoke with the researchers, who come from Inha University, the Daegu Gyeongbuk Institute of Science & Technology (DGIST), the University of Central Florida (UCF), and the Cyber Security Department at Ewha Womans University (EWU). The system, called SSD-Insider, is supposedly almost 100 percent accurate and has been tested on real-world ransomware.
