As I was scrolling down, I saw the top 3/4 of the wings, and thought it was a frog. I guess that's the reason for the pattern.

"Project Noah Fun Fact: Considered to be the most widespread dragonfly on the planet, occurring between about the 40th parallels of latitude or within the 20 °C isotherm (areas of the world where the annual mean temperature is above 20 degrees Celsius). Especially in the autumn, the wandering glider flies in large swarms, using thermals to advantage.

Good article. It tells you how a toxicologist assesses the problem, quantifies the risks, highlights the limitations of the assessment and gives the recommendation: if used properly, Teflon pans are relatively safe to use. My rule-of-thumb: any 'health' article that screams XXX is bad/good for you without this kind of info should be ignored and not shared. "Before I answer, let me give a quick overview of how us toxicologists approach these kinds of questions. When assessing safety of any chemical or component, there are two types of information that needs to be gathered: hazard characterization and exposure assessment. In other words, what is the toxic compound and what toxic effects might it cause (hazard characterization)? Then, are people exposed to the compound? If so, how does it get into the body? And how much? Is the amount people are exposed to enough to cause harmful effects (exposure assessment)? Toxicologists design experiments to generate these two types of information.

Integrating these pieces of information allows us to make our best estimate of the risk of chemicals being toxic to humans, a form of risk assessment. These are only estimates since much of this information is sometimes difficult to obtain practically (you can’t expose humans to potentially toxic compounds in a study!). Thus, we must rely on animal studies, testing individual cells, and computer models. Now, lets apply this method to non-stick pans.
[...]
In conclusion, to my dear newlywed friends and other interested readers, is it safe to use non-stick frying pans and cookware? Assuming you use your cookware appropriately, i.e. not heating it excessively and unattended, always heating the pan with something in it, not scratching off the Teflon and consuming it for dinner, using non-stick pans is relatively safe for humans."

"SINGAPORE: The Republic's largest public hospital, Singapore General Hospital (SGH), will be redeveloped over the next 20 years – including moving it closer to Outram Park MRT station – to better serve patients.

A master plan was unveiled on Friday (Feb 5) to redevelop the hospital, together with the other facilities on the 43-hectare SGH campus – SingHealth Duke-NUS Academic Medical Centre, five national specialty centres and a polyclinic.

Prime Minister Lee Hsien Loong, who was the guest of honour at the launch of the master plan, said while it would be a "musical chairs exercise" to keep the busy hospital running while shifting buildings and roads around, 50 years would have passed since the last redevelopment by the completion of the plan – "not too early to fit out and have a new campus fit to serve the next generation of Singaporeans".
[...]
Mr Lee said that while upgrading, the old buildings in the campus will be preserved or re-purposed where possible "to remind us of our heritage". 
He cited as an example Bowyer block, the only building still standing from 1926, which now houses the SGH Museum and outpatient services.

"It reminds us of how we have built and upgraded SGH over more than a century to serve Singaporeans and commemorates those who have given their lives to public healthcare," he said. 

"These are values that we must preserve, even as we upgrade the buildings around us because that is how we can take care of each other well."
A master plan to redevelop the 43-hectare SGH campus over the next 20 years will help the healthcare system better serve patients, Prime Minister Lee Hsien Loong says.

"A strange fossil wildebeest had hollowed-out headgear that let it trumpet like a dinosaur.

The Ice Age beast, named Rusingoryx atopocranion, lived on Kenya’s Rusinga Island between 75,000 and 50,000 years ago, back when the area was carpeted in dry grasslands. The species was previously only known from partial skulls, but now a bonebed has revealed that they were more bizarre than anyone expected.
[...]
Incomplete fossils had led paleontologists to suspect Rusingoryx had some kind of tapir-like proboscis, but the new skulls showed that the mammal instead had a high nasal dome in front of its eyes. And it was hollow, encasing a circuitous nasal passage.
[...]
Royal Ontario Museum paleontologist David Evans, an expert on hadrosaurs, says he was “blown away” by the Rusingoryx skulls and that “the resemblance between Rusingoryx and some hollow-crested dinosaurs in the form of the nasal structures is truly striking.”"

Fighting fire with fire; or rather, Wolbachia. "SYDNEY, Australia — Early next week, Michelle Littman plans to take a small cardboard noodle box, with some twine for a handle, into an overgrown part of her tropical suburban garden and do something rather counterintuitive — breed mosquitoes.
[...]
The idea defies conventional wisdom. “All my life, I’ve been told to dry out puddles of water to stop mosquitoes’ breeding,” Ms. Littman, 52, said in a telephone interview. “Now, I’m breeding them from eggs in a box hanging from a heliconia tree in my own backyard.”

Even so, people in Townsville and Cairns, 215 miles to the north, are eagerly participating in the experiment, which is being run by Monash University. The plan depends on microbes called Wolbachia bacteria. If they are present in a mosquito, it cannot become a carrier of a wide range of dangerous pathogens, including dengue, yellow fever, chikungunya, and Zika. And when it breeds, it passes the Wolbachia bacteria to its offspring, and they also cannot carry those diseases.

The university’s dean of science, Scott O’Neill, and his team have injected hundreds of thousands of Aedes aegypti mosquito eggs with Wolbachia bacteria, and participants in the trial like Ms. Littman and her neighbors are hatching and releasing them.
[...]
“The science has been slow, and technically very challenging,” Dr. O’Neill said in a telephone interview Wednesday from Yogyakarta, Indonesia, where he is conducting field trials. “But we are now achieving scale, and our results look promising.”"
Residents in parts of Queensland are taking part in trials to breed mosquitoes from eggs injected with a bacteria that blocks the pests from carrying diseases like Zika and dengue.

There are no large caverns inside Comet #67P/Churyumov-Gerasimenko. ESA’s #Rosetta mission has made measurements that clearly demonstrate this, solving a long-standing mystery.

Family went for a walk at Venus Drive, Singapore, this morning. Besides the usual butterflies and dragonflies, which I'll include in an album on the walk, the family spotted these cool wonders: a pond skater, a colourful tiger beetle, a group of barklice, a hammerhead worm, an asiatic honey bee nest and hover flies.

This USB Type C cable is to be avoided at all costs.
 
PSA : Take a look at the cable in the picture below. If you find a deal online for a cable that looks anything like this on Amazon, Ebay, or a site like Alibaba, don't buy it. AVOID IT AT ALL COSTS.

I've looked through my history of reviews online and I have in the past purchased at least 8 different variants of this cable for review. I dug up each of these cables from my collection of bad cables since the SurjTech cable (which looks exactly like the one in the picture) fried my equipment and did some additional testing.

With some exceptions, most cheaper cables you'll buy on Amazon aren't manufactured by the brand that sells them to you. They typically go to some common suppliers with specifications and put their brand on it. (as an aside, that's why cables from iOrange-E, Cambond, F-color, and other brands are so similar in a good way).

In this case, there is a common manufacturer for the following brands that I can see on Amazon today : 
* iKNOWTECH
* NXET
* SurjTech
* TRADERPLUS
* SAWAKE

What's troubling is that when I examine the different variants of the cables from this common manufacturer, none of the variants are correctly configured using a 56 kΩ resistor, but their errors are also not consistent!

Here are the types of errors I found with this kind of cable : 
1) No CC termination
2) 5.1kΩ pullup 
3) 5.1kΩ pulldown
4) 10 kΩ pullup
5) Swapped Vbus and Gnd + 10kΩ pulldown

The last kind of cable killed my equipment. It almost seems like the manufacturer is just trying random permutations of settings and pushing out the result into the market. Scary...

Furthermore, and here's the coup de grace, EVERY one of these cables claim to be SuperSpeed 10gbps USB 3.1 cables with the logo (the SuperSpeed trident below), the packaging, and the Amazon listings.

Every single one of these "strong" braided cables are missing the 4 additional SuperSpeed wires + 1 ground return needed by SuperSpeed. This is such a terrible deception. :(

I urge anyone to keep an eye out for this kind of cable and simply ignore it. I will leave as many negative reviews as I can, but it seems like random sellers pop up on Amazon and elsewhere selling this deceptive product every day.

USB-C are (potentially) high current, making protection with small, inexpensive components infeasible. The USB Implementers Forum (the consortium that developed the spec) should require electrical certification (UL, CE, CSA, etc.) to carry the trademark.

Not quite. I find this article very enlightening to understand how mosquitoes spread (or don't spread) diseases [ https://cameronwebb.wordpress.com/2014/10/20/why-dont-mosquitoes-spread-ebola/ ]:

" Mosquitoes are just flying syringes aren’t they?

Mosquitoes are not flying syringes. They don’t transmit pathogens by transferring small infected droplets of blood. There is a complex biological process between the mosquito and the pathogen that must be completed before transmission can occur. In addition, there are ecological questions regarding the diversity, abundance, distribution and host-feeding patterns of local mosquitoes that can all influence the importance of mosquitoes in outbreaks of disease.

Unraveling these biological factors can be a complex process."

I wrote a column in October for The New York Times about the first recovery of an ancient African genome. Part of that study now looks to be wrong. So I wrote a new column this week. Beats a correction notice! http://www.nytimes.com/2016/02/05/science/dna-study-of-first-ancient-african-genome-flawed-researchers-report.html 
When other researchers studied the 4,500-year-old-genome, they discovered that the conclusion that much of Africa has Eurasian ancestry was incorrect.
