Female Shark Learns To Reproduce Without Males After Years Alone

An anonymous reader quotes a report from New Scientist: A female shark separated from her long-term mate has developed the ability to have babies on her own. Leonie the zebra shark (Stegostoma fasciatum) met her male partner at an aquarium in Townsville, Australia, in 1999. They had more than two dozen offspring together before he was moved to another tank in 2012. From then on, Leonie did not have any male contact. But in early 2016, she had three baby sharks. Intrigued, Christine Dudgeon at the University of Queensland in Brisbane, Australia, and her colleagues began fishing for answers. One possibility was that Leonie had been storing sperm from her ex and using it to fertilize her eggs. But genetic testing showed that the babies only carried DNA from their mum, indicating they had been conceived via asexual reproduction. Some vertebrate species have the ability to reproduce asexually even though they normally reproduce sexually. These include certain sharks, turkeys, Komodo dragons, snakes and rays. However, most reports have been in females who have never had male partners. In sharks, asexual reproduction can occur when a female’s egg is fertilized by an adjacent cell known as a polar body, Dudgeon says. This also contains the female’s genetic material, leading to “extreme inbreeding”, she says. “It’s not a strategy for surviving many generations because it reduces genetic diversity and adaptability.” Nevertheless, it may be necessary at times when males are scarce. “It might be a holding-on mechanism, ” Dudgeon says. “Mum’s genes get passed down from female to female until there are males available to mate with.” It’s possible that the switch from sexual to asexual reproduction is not that unusual; we just haven’t known to look for it, Dudgeon says.

5G Internet is the ‘Beginning of the Fourth Industrial Revolution’

Next-generation 5G mobile internet technology marks the beginning of the “fourth industrial revolution, ” the chief executive of Turkey’s leading telecoms player told CNBC on Thursday. From a report: 5G is viewed as a technology that can support the developing Internet of Things (IOT) market, which refers to millions — or potentially billions — of internet-connected devices that are expected soon to come on to the market. Kaan Terzioglu, the chief executive of Turkcell, which has a market capitalization of $23 billion, touted the potential of the technology, saying that while 4G revolutionized the consumer market, 5G could transform the industrial space. “I think this is the beginning of the fourth generation of the industrial revolution. This will be the platform linking billions of devices together, ” Terzioglu told CNBC at the World Economic Forum in Davos. Turkcell has been working on 5G technologies since 2013 and this week completed a test in partnership with Ericsson, using the next-generation internet. Read more of this story at Slashdot.

Malwarebytes Discovers ‘First Mac Malware of 2017’

wiredmikey writes: Security researchers have a uncovered a Mac OS based espionage malware they have named “Quimitchin.” The malware is what they consider to be “the first Mac malware of 2017, ” which appears to be a classic espionage tool. While it has some old code and appears to have existed undetected for some time, it works. It was discovered when an IT admin noticed unusual traffic coming from a particular Mac, and has been seen infecting Macs at biomedical facilities. From SecurityWeek.com: “Quimitchin comprises just two files: a .plist file that simply keeps the .client running at all times, and the .client file containing the payload. The latter is a ‘minified and obfuscated’ perl script that is more novel in design. It combines three components, Thomas Reed, director of Mac offerings at Malwarebytes and author of the blog post told SecurityWeek: ‘a Mac binary, another perl script and a Java class tacked on at the end in the __DATA__ section of the main perl script. The script extracts these, writes them to /tmp/ and executes them.’ Its primary purpose seems to be screen captures and webcam access, making it a classic espionage tool. Somewhat surprisingly the code uses antique system calls. ‘These are some truly ancient functions, as far as the tech world is concerned, dating back to pre-OS X days, ‘ he wrote in the blog post. ‘In addition, the binary also includes the open source libjpeg code, which was last updated in 1998.’ The script also contains Linux shell commands. Running the malware on a Linux machine, Malwarebytes ‘found that — with the exception of the Mach-O binary — everything ran just fine.’ It is possible that there is a specific Linux variant of the malware in existence — but the researchers have not been able to find one. It did find two Windows executable files, courtesy of VirusTotal, that communicated with the same CC server. One of them even used the same libjpeg library, which hasn’t been updated since 1998, as that used by Quimitchin.” Read more of this story at Slashdot.

Hackers Corrupt Data For Cloud-Based Medical Marijuana System

Long-time Slashdot reader t0qer writes: I’m the IT director at a medical marijuana dispensary. Last week the point of sales system we were using was hacked… What scares me about this breach is, I have about 30, 000 patients in my database alone. If this company has 1, 000 more customers like me, even half of that is still 15 million people on a list of people that “Smoke pot”… ” No patient, consumer, or client data was ever extracted or viewed, ” the company’s data directory has said. “The forensic analysis proves that. The data was encrypted — so it couldn’t have been viewed — and it was never extracted, so nobody has it and could attempt decryption.” They’re saying it was a “targeted” attack meant to corrupt the data rather than retrieve it, and they’re “reconstructing historical data” from backups, though their web site adds that their backup sites were also targeted. “In response to this attack, all client sites have been migrated to a new, more secure environment, ” the company’s CEO announced on YouTube Saturday, adding that “Keeping our client’s data secure has always been our top priority.” Last week one industry publication had reported that the outage “has sent 1, 000 marijuana retailers in 23 states scrambling to handle everything from sales and inventory management to regulatory compliance issues.” Read more of this story at Slashdot.

Hamas ‘Honey Trap’ Dupes Israeli Soldiers

wiredmikey quotes Security Week: The smartphones of dozens of Israeli soldiers were hacked by Hamas militants pretending to be attractive young women online, an Israeli military official said Wednesday. Using fake profiles on Facebook with alluring photos, Hamas members contacted the soldiers via groups on the social network, luring them into long chats, the official told journalists on condition of anonymity. Dozens of the predominantly lower-ranked soldiers were convinced enough by the honey trap to download fake applications which enabled Hamas to take control of their phones, according to the official.

MIT Unveils New Material That’s Strongest and Lightest On Earth

A team of MIT researchers have created the world’s strongest and lightest material known to man using graphene. Futurism reports: Graphene, which was heretofore, the strongest material known to man, is made from an extremely thin sheet of carbon atoms arranged in two dimensions. But there’s one drawback: while notable for its thinness and unique electrical properties, it’s very difficult to create useful, three-dimensional materials out of graphene. Now, a team of MIT researchers discovered that taking small flakes of graphene and fusing them following a mesh-like structure not only retains the material’s strength, but the graphene also remains porous. Based on experiments conducted on 3D printed models, researchers have determined that this new material, with its distinct geometry, is actually stronger than graphene — making it 10 times stronger than steel, with only five percent of its density. The discovery of a material that is extremely strong but exceptionally lightweight will have numerous applications. As MIT reports: “The new findings show that the crucial aspect of the new 3-D forms has more to do with their unusual geometrical configuration than with the material itself, which suggests that similar strong, lightweight materials could be made from a variety of materials by creating similar geometric features.” Read more of this story at Slashdot.

Fewer People Are Dying of Cancer Than Ever Before

The number of Americans dying of cancer has dropped to a 25-year low, equaling an estimated 2, 143, 200 fewer deaths in that period, says the new annual report from the American Cancer Society. In that time, the racial and gender disparities that exist in cancer rates have also narrowed somewhat, but they remain wide in many places. From a report on The Outline: Though the incidence of cancer remained stable for women and dropped slightly — by 2 percent — in men, rates remain overall 20 percent higher in men while rate of death for men is 40 percent higher than in women. The rates of both incidence and death vary wildly based on the type of cancer. The data that the ACS is using run through the end of 2014 for incidents of cancer and through 2013 for deaths. Lung cancer remains the leading cause of cancer death in the United States for both men and women.. Read more of this story at Slashdot.
