The first time when I saw the wheels I was wondering why the hell they spend so much money to send up a robot to Mars and then equip that thing with such flimsy wheels

And I did post question here on /, and there were people (NASA fanbois, perhaps) defending those flimsy wheels

Researchers at the Defense Advanced Research Projects Agency (DARPA) want to explore the possibility of seriously changing that notion and develop what it calls “a system-of-systems architecture and critical components to support networked maritime operations, to include undersea, surface, and above surface domains.”"

+ - Last universal ancestor (LUA) may have a 'leaky' membrane->

Submitted by Taco Cowboy
Taco Cowboy (5327) writes "Around four billion years ago the Last Universal Ancestor (LUA), most probably a single cell organism, appeared on Planet Earth. In order to be alive that single cell organism must be able to harness energy from its surrounding, and in order to do that, according to researchers at University College London (UCL), that single cell organism had a 'leaky' membrane which allowed protons to enter and exit at the same time

The UCL researchers came to the conclusion using mathematical modeling, in which the findings were published on August 13, 2014, in PLOS Biology

The study claims this membrane may explain why all cells use the same complex mechanism to harvest energy, and it may also explain why two types of fundamental single-celled organisms — bacteria and archaea — have different cell membranes

The leakiness of the membrane allowed LUA to be powered by energy in its surroundings, most likely vents deep on the ocean floor, while holding in all the other components necessary for life. The team modeled how the membrane changed, enabling LUA’s descendants to move to new, more challenging environments and evolve into two distinct types of single-celled organism, bacteria and archaea, creating the deepest branch of the tree of life

Bacteria and archaea share many common features such as genes, proteins and mechanisms of reading DNA, initially leading scientists to believe they were just different types of bacteria. Their classification changed in the 1970s after extreme differences were found in the way they replicate DNA and in the structure of their cell membrane. As they both stemmed from LUA, scientists set out to find answers in the structure and function of LUA’s membrane

Data from the study strongly suggest that LUA lived in the area where ancient seawater, dense with positively charged particles called protons, mixed with warm alkaline vent fluid, which contained few protons. The difference in the concentration of protons across these two environments enabled protons to flow into the cell, driving the production of a molecule called adenosine triphosphate (ATP) which powered the growth of cells, just as it does today. However, unlike modern cells the scientists believe this could only happen if the membrane was 'leaky', enabling protons to leave the cell spontaneously so more protons could enter to power growth

From a single basic idea, the model can explain the fundamental differences between bacteria and archaea. In these deep sea vents, there is a continuous flow of alkaline fluids, which mix with the ocean waters. When they mix, the fluids neutralize each other, and that stops any build-up of charge which would otherwise prevent protons flowing into the cell

If the first cells had leaky membranes, then protons could enter and then be neutralized, or leave again, almost as if there was no barrier at all

The mathematical modeling shows that the rate at which protons enter and leave was high enough to power the growth of cells via proteins embedded in the membrane. LUA could have been powered by natural proton gradients in vents, but only if it had a really leaky membrane, completely unlike today’s cells"

+ - Stem cell research breakthrough from transparent fish 1

Submitted by brindafella
brindafella (702231) writes "Australian scientists have accidentally made one of the most significant discoveries in stem cell research, by studying the transparent embryos of Zebrafish (Danio rerio). The fish can be photographed and their development studied over time, and the movies can be played backwards, to track back from key developmental stages to find the stem cell basis for various traits of the fish. This fundamental research started by studying muscles, but the blood stem cell breakthrough was a bonus. They've found out how hematopoietic stem cells (HSC), among the most important stem cells found in blood and bone marrow, is formed. The scientishs are based at the Australian Regenerative Medicine Institute at Monash University. The research has been published in the Nature medical journal. This discovery could lead to the production of self-renewing stem cells in the lab to treat multiple blood disorders and diseases."

angry tapir (1463043) writes "Apple has done well to insulate its iOS mobile operating system from many security issues, but a forthcoming demonstration shows it's far from perfect. Next Wednesday at the Usenix Security Symposium in San Diego, researchers with the Georgia Institute of Technology will show how iOS's Achilles' heel is exposed when devices are connected over USB to a computer or have Wi-Fi synching enabled. The beauty of their attack is that it doesn't rely on iOS software vulnerabilities, the customary way that hackers commandeer computers. It simply takes advantage of design issues in iOS, working around Apple's layered protections to accomplish a sinister goal."

Submitted by Anonymous Coward
An anonymous reader writes "Ryan Lackey of CloudFlare and Marc Rogers of Lookout revealed a new OPSEC device at Def Con called PORTAL (Personal Onion Router to Assure Liberty). It "provides always-on Tor routing, as well as 'pluggable' transport for Tor that can hide the service's traffic signature from some deep packet inspection systems." In essence, PORTAL is a travel router that the user simply plugs into their existing device for more than basic Tor protection (counterpoint to PogoPlug Safeplug and Onion Pi). On the down side, you have to download PORTAL from Github and flash it "onto a TP-Link compatible packet router." The guys behind the device acknowledge that not many people may want to (or even know how to) do that, so they're asking everyone to standby because a solution is pending."

Submitted by alphadogg
alphadogg (971356) writes "Cisco Systems will cut as many as 6,000 jobs over the next 12 months, saying it needs to shift resources to growing businesses such as cloud, software and security. The move will be a reorganization rather than a net reduction, the company said. It needs to cut jobs because the product categories where it sees the strongest growth, such as security, require special skills, so it needs to make room for workers in those areas, it said. “If we don’t have the courage to change, if we don’t lead the change, we will be left behind,” Chairman and CEO John Chambers said on a conference call."

+ - Exercising to excess increases risk of death->

Submitted by Taco Cowboy
Taco Cowboy (5327) writes "A new research involving 2,400 heart attack survivors conducted in Hartford Hospital reveals that too much exercise may increase risk of death to heart attack survivors

For normail heart attack survivors the more exercise they do, the less risk they face of dying from heart disease – up to a point.

Benefits began to decline among those who ran more than 48km per week; Among walkers, the turning point, when benefits were lost, was seen in those who did more than 74km per week, or 10.5km per day

Remarkable dose-dependent reductions in deaths from cardiovascular events of up to 65 percent were seen among patients who were running less than 30 miles or walking less than 46 miles per week

About 5 hours of vigorous exercise per week is the 'safe upper range'; Also, people should not engage in high-intensity exercise every day and should abstain from exercising 1-2 days a week

The researchers cautioned that since their study focused on heart attack survivors, their results might not be generalisable to the population at large"

+ - Giant Greek tomb discovered->

Submitted by schwit1
schwit1 (797399) writes "Archeologists have uncovered the largest tomb ever discovered in Greece and think it is linked to the reign of Alexander the Great.

The tomb, dating to around 300 BC, may have held the body of one of Alexander’s generals or a member of his family. It was found beneath a huge burial mound near the ancient site of Amphipolis in northern Greece. Antonis Samaras, Greece’s prime minister, visited the dig on Tuesday and described the discovery as “clearly extremely significant”.

A broad, five-yard wide road led up to the tomb, the entrance of which was flanked by two carved sphinxes. It was encircled by a 500 yard long marble outer wall. Experts believe a 16ft tall lion sculpture previously discovered nearby once stood on top of the tomb.

The excavations began in 2012, and by this month hope to identify who actually was buried there."

Each year the research firm Gartner puts out a Hype Cycle of emerging technologies, a sort of report card for various trends and buzzwords. This year, IoT tops the list. On another note, somewhat surprising is that Gartner says the "cloud computing" is not just hype anymore, but becoming a mainstream technology."

+ - Lucid Dreams may be better in solving problems->

Submitted by Taco Cowboy
Taco Cowboy (5327) writes "According to a study of University of Lincoln, UK, lucid dreamers have better problem-solving abilities

In the first empirical study on the subject, "Lucid Dreamers”, those who actually know they are dreaming while the dreams play out, exhibit better problem-solving abilities in their day-to-day lives

"It is believed that for dreamers to become lucid while asleep, they must see past the overwhelming reality of their dream state, and recognise that they are dreaming," said Patrick Bourke, senior lecturer at the Lincoln School of Psychology. "The same cognitive ability was found to be demonstrated while awake by a person's ability to think in a different way when it comes to solving problems"

For the study, the researchers observed the cognitive ability in 68 participants, aged between 18 and 25 years, who had experienced different levels of lucid dreaming, ranging from never to several times a month. The participants were asked to solve 30 problems intended to test their insight.The researchers said that each problem comprised of three words and a solution word. Each of the three words could be combined with the solution word to form a new compound word. For example, with the words 'sand', 'mile' and 'age', the linking word would be 'stone'

They found that frequent lucid dreamers solved 25 per cent more of the insight problems than non-lucid dreamers"

Historians Rediscover Einstein's Forgotten Model of the Universe 35

Posted by samzenpus
from the rough-draft dept.
KentuckyFC writes In 1931, after a 3- month visit to the U.S., Einstein penned a little known paper that attempted to show how his theory of general relativity could account for some of the latest scientific evidence. In particular, Einstein had met Edwin Hubble during his trip and so was aware of the latter's data indicating that the universe must be expanding. The resulting model is of a universe that expands and then contracts with a singularity at each end. In other words, Einstein was studying a universe that starts with a big bang and ends in a big crunch. What's extraordinary about the paper is that Einstein misspells Hubble's name throughout and makes a number of numerical errors in his calculations. That's probably because he wrote the paper in only 4 days, say the historians who have translated it into English for the time. This model was ultimately superseded by the Einstein-de Sitter model published the following year which improves on this in various ways and has since become the workhorse of modern cosmology.
