Authors of the report propose possibilities that include involvement of small amounts of water, indicated by detection of hydrated salts observed at some of the flow sites.
There are still unanswered questions, such as why the streaks appear and vanish with the seasons, and what makes them dark in color.
Scientists, including those from the University of Arizona in the USA and Durham University in the United Kingdom analysed narrow, down-slope trending surface features on Mars that are darker than their surroundings, called Recurring Slope Linea (RSL).
Speaking about this research, US Geological Survey's Colin Dundas explains, "We've thought of RSL [recurring slope lineae] as possible liquid water flows, but the slopes are more like what we expect for dry sand".
"This new understanding of RSL supports other evidence that shows that Mars today is very dry", said Dundas, lead author of the study published in the journal Nature Geoscience. This is based in part on assessments made with the Mars orbiter's telescopic camera. The data include 3-D models of slope steepness using pairs of images for stereo information.
However, all of the 151 RSLs examined in the study were found to all end on similar slopes despite very different lengths.
One of the reasons for the change is that scientists found that RSL were only visible on steep slopes.
The scientists concluded that the range "matches that of slipfaces for active Martian and terrestrial dunes, interpreted as the range of critical angles for which granular flows of sand can terminate".
It was previously thought that this could provide evidence of water flow.
"RSL probably form by some mechanism that is unique to the environment of Mars, so they represent an opportunity to learn about how Mars behaves, which is important for future surface exploration", said Alfred McEwen from the University of Arizona, Tucson, a co-author on the study.
These findings indicate that it is hard for Earth-like life to exist near the surface of Mars owing to the water-restricted conditions that exist on the planet.
SCIENTISTS have dashed hopes of Mars supporting alien life after realising the mysterious "water" marks were actually left by SAND.
Tzion left Saudi Arabia a few days ago and is now in a country that has diplomatic relations with Israel. Interestingly, Ben Tzion has also posted some images captured from the Iranian cities of Tehran and Qom.
Commenting on the British action, it said, "The UK chose to withdraw its candidate after a closely fought electoral process". For a victory, it was necessary to get majority support both at the UN General Assembly (UNGA) as well as at the UNSC .

Taking after the main franchise for the Nintendo DS and 3DS, Animal Crossing: Pocket Camp starts small and gets progressively big. The Leaf Tickets will speed certain things up for you in-game if you don't want to wait, but they're completely optional as well.

They have the broadest impact on PC users: they allow arbitrary remote code execution and privileged information access. Intel released a detection tool to enable Windows and Linux administrators to check if their systems are vulnerable.
Earlier this week, a CNN report said another woman accused Franken of inappropriately grabbing her during a photo op in 2010. He has apologized to Tweeden, and she has accepted the apology, but a handful of Democrats have called for him to resign.
He is now allowed to explore new business opportunities not just in components but in mobile and consumer electronics, too. He is also in charge of the Samsung Strategy and Innovation Center (SSIC), with offices in San Jose and San Francisco.
The struggle is not over — Zimbabwe
The nationalist discourse of many independence movements, which still shapes African politics today, has little room for women. The commanders are also bona fide members of the ruling party and guarantors of Zanu-PF power .
Tillerson declares Myanmar violence as 'ethnic cleansing'
Burke said Myanmar's Catholic cardinal, Charles Bo, had proposed during a weekend audience with Francis that he meet with Gen. But while Washington has shifted gears rhetorically, it hasn't taken any steps to punish Myanmar's government just yet.
L'absentéisme augmente dans le privé — Arrêt maladie
