 have up to 350 cloudless days a year. "If you have a number of receiving stations, there's almost no chance they'd all be clouded out," said Dr Martin Harwit.
Because the narrow laser beam would target the signal better than a radio beam, less energy would go astray, and onboard power consumption would be slashed. A laser would need only a fraction of the power of today's transmitters.
Last year the European Space Agency tested a laser link between two satellites, SPOT-4 and Artemis. NASA too is exploring the option of laser communications.
The technique would work well for spacecraft orbiting Mars, 400 million kilometres away, according to Dr Bland-Hawthorn.
The Science paper calls for "energetic action" from the scientific community to head off the looming crisis in data transmission.
"Space missions flying ten years from now will collect huge amounts of data," said Dr Alex Harwit. "We'd like to see work start now on a laser telemetry system that can handle it."
"Astronomers, weather forecasters, resource managers -- anybody who uses a satellite or spacecraft would benefit from this new technology," said Dr Andrew McGrath of the Anglo-Australian Observatory.

New networking protocols are desired essentially in future Optical Wide Area Network (OWAN) environments to meet increasing demands of communication with low latency and high bandwidth. In this paper, a simulation study based on 100 nodes random topology is conducted to observe packet delay patterns and efficient link utilization for two session traffic sources Exponential and CBR (Constant Bit Rate), with number of wavelengths (16, 32, 48 and 64) while varying packet sizes ranging from 100 to 1000 bytes. By using OWns (Optical WDM network simulator), an optimal packet size is presented for Exponential session traffic as one of the design considerations of new protocol in Wavelength Routed Optical Networks (WRONs) with Wavelength Division Multiplexing (WDM) technology. Simulation results also show that Exponential session traffic performs better as compare to CBR session traffic in terms of average packet delay and link utilization.---------- ïµ ----------1.

ever since my life took an interesting turn 5 years ago, i’ve been a big believer in intuitive eating. you can google it if you want to learn more, but the premise is, pay attention to your body when you eat, if you listen you will know what and how much you should be eating. it is something that has helped me get past many many hard times – helped me stay healthy. it is eating without “food rules”, diets or other odd made up concepts that just don’t work. it is eating because you are hungry, because food is enjoyable, and stopping when you’ve had enough. the “eat like your grandparents diet”? it’s that – pay attention to how you feel and you will know what’s right.
this week i had an interesting conversation – one that has left me thinking a whole lot about the concept and brought up things that i’ve mentioned in this blog before – how hard it is to eat intuitively without rules when my allergies and health problems sometimes dictate rules. i’ve written about my allergies before and i’ve written about my struggles with eating on other blogs but i’ve never really written about the fact that i have PCOS (polycystic ovarian syndrome) and this is where the idea of eating without rules get confusing and complicated. there are many things that PCOS affect health wise, but the big one that most of us deal with is insulin resistance – it causes weight gain, weird blood sugar swings and really strong cravings for carbs – and i mean REALLY strong (crying because i want a cookie and don’t have access to one happens, a lot). there are times when even if i listen to my body, it tells me lies. it tells me that it wants sugar, large amounts of glorious sugar that will in turn make me sick when my blood sugar skyrockets then drops like a ton of bricks. we have arguments sometimes. i know i’ve eaten enough but it wants more. sometimes i win by trying to tell it that it’s just confused, and sometimes i lose when it decides to drop my blood sugar (and therefore dropping me onto the floor). it’s hard to tell when it is telling the truth and when it lies….and it’s frustrating. somedays i can eat almost exactly the same time, exercise the same amount and still one day i will be fine and the next day not. my body lies, my body plays games and sometimes, just sometimes, i am sure it hates me.
i’m struggling right now. it’s scary to know that you’ve worked so hard to become healthy again after being so ill for so long and know that there is a possibility that even if you try really really hard that sometimes it won’t matter. that even on days you are “perfect” it isn’t enough.
so many of us suffer silently…”female problems” are not something that is acceptable public conversation, but the truth is, i wish i could scream about it, scream about how someone making a comment and losing or gaining weight makes me want to go off the deep end. how someone questioning the fact that i eat 5 or 6 times a day and how if they “did that” they surely “would be fat” makes me feel as if i’m going to gain weight at any minute now ballooning up into just another “statistically confirmed risk group” i want to scream that i just want to eat like everyone else, i don’t want to watch my protein to carb ratio, i don’t want to have to check my blood sugar sometimes and i really don’t want to have to remember to bring candy with my when i go for a walk with my dog “just incase” my blood sugar drops.
i want my body and i to call a truce…Working with Station Road Steam Ltd, the Taylor Kellar Partnership has developed a 21st-century equivalent of James Watt’s Indicator.

Whether you are looking for your very first e-cigarette, or you already vape and are looking to upgrade your kit, it's important to know the difference between the different types of vape kit.
We've broken these down into the three main types of device below, with information on how they're constructed, who they are suited to and how to get started with them. But first, if you're completely new to vaping, here's a little background information on the world of vaping.
As explained in further detail in our History of E Cigarettes article, electronic cigarettes (also known as e cigarettes, e cigs, vapes or vape kits) have probably been around for longer than you think. The first electronic cigarette was actually invented in 1963!
Their popularity has increased hugely over the last few years with technology, devices and flavours rapidly advancing. With so many different vape devices now available and so many different terms used to describe them,
