Malware found preinstalled on 38 Android phones used by 2 companies

Enlarge (credit: portal gda ) A commercial malware scanner used by businesses has recently detected an outbreak of malware that came preinstalled on more than three dozen Android devices. An assortment of malware was found on 38 Android devices belonging to two unidentified companies. This is according to a blog post published Friday by Check Point Software Technologies, maker of a mobile threat prevention app. The malicious apps weren’t part of the official ROM firmware supplied by the phone manufacturers but were added later somewhere along the supply chain. In six of the cases, the malware was installed to the ROM using system privileges, a technique that requires the firmware to be completely reinstalled for the phone to be disinfected. “This finding proves that, even if a user is extremely careful, never clicks a malicious link, or downloads a fishy app, he can still be infected by malware without even knowing it,” Check Point Mobile Threat Researcher Daniel Padon told Ars. “This should be a concern for all mobile users.” Read 4 remaining paragraphs | Comments

Scientists put mouse embryos in suspended animation for a month

A team of scientists from the University of California, San Francisco only wanted to slow down mice embryos’ cell growth in the lab. Instead, they managed to completely pause their development, putting the blastocysts (very early embryos) in suspended animation for a month. What’s more, they found that the process can put stem cells derived from the blastocysts in suspended animation, as well. Okay, let’s face it: that doesn’t sound nearly as cool as putting humans in suspended animation. But their finding still has huge implications for various fields of medicine. Doctors could develop a way to suspend embryos for IVF and scientists could find a method to slow down aging, among other possibilities. Helps that the researchers were able to prove that the embryos can develop normally even after a pause in their growth. Team member Ramalho-Santos from the Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research said: “It was completely surprising. We were standing around in the tissue culture room, scratching our heads, and saying wow, what do we make of this? To put it in perspective, mouse pregnancies only last about 20 days, so the 30-day-old ‘paused’ embryos we were seeing would have been pups approaching weaning already if they’d been allowed to develop normally.” So, what exactly did the team do that led to their finding? They used a drug that inhibited the activities of a protein called mTOR, which regulates different cellular processes. By inhibiting the protein, they also inhibit the cells’ activities. In the future, the researchers want to explore mTOR inhibitors’ capability to pause stem cells’ activities in the late stages of their development, which could be used to repair or replace organs. And since other studies already showed that mTOR inhibitors can extend the lives of mice, the researchers want to explore their possible uses in aging research.
