Do Plants Have Memory?

Most of us see plants as passive organisms: they don't move, they don't run, and they don't retaliate when you put them under the chainsaw. 

Of course, plants do move. You can find plenty of timelapse videos of flower blossoming and twigs moving on youtube, and some plants can even act fast enough to capture insects.

New Year Resolution 2016 and 2015 Year In Review

Hi all,
It's been a while since I last came here. You know lah, peeper busy mar.

Okay, I'll begin by taking a look back over the past 12 months. 2015 has been a ... pretty good year really-much better than 2014, that's for sure. However, I didn't manage to achieve some of the resolution I set last time around.

1) Run a 42-km marathon 
Well, to be fair the marathon was canceled due to the terrible haze condition. I was lucky someone asked me if I wanted to sell the bib a month before the event, and so I did (because I knew what was coming, you see).
2) Get a pet
Live in condo. No pet allowed.
3) Diving's licence
Got it. Yaay~~~
4) Shoot a music video
Um.. I did shoot something, albeit not a music video. Still, well, practically it's a video so yeah.
5) Publish at least one paper
I've submitted some papers but the reviewers kept on rejecting them. At least I've tried...
6) Limit facebook usage
Okay I overestimated my self discipline for this one. I'll do another one this year.
7) Visit a foreign country
I visited no one, but TWO foreign countries (Japan and China).

In addition to the abovementioned items, I've also done a timelapse video (which took 13 months to make), did multiple music covers, and visited Taman Negara by motorcycle.

So what's for 2016? What do you think I should achieve this year?
Well I think I'd like to do these:

1) Finish a book every month. Actually I can finish a book in a week but let's not repeat the overconfidence mistake again.
2) Run a 42-km  21-km half marathon. To be honest, I'm in really bad shape right now-my stamina is bad and I couldn't even finish a 5.5km run last week. To make matters worse, I've sustained an ankle injury from a futsal session in September and it's still bothering me to this day. So I think the prudent thing to do is not to rush to complete this 42-km thing.
3) Publish paper. I have planned to submit four papers this year. Wish me luck!
4) No traveling outside the country. I don't think I'll be traveling to any foreign country in 2016. Initially I have planned to visit Taiwan in 2016, but considering the falling oil price and the resulting weak Ringgit maybe I'll just settle for some random islands in Sabah or the east coast.

Alright.
Just four simple new year resolution for 2016. I think it would be wise to keep it simple and short so that I would remember to try to accomplish them all.
Lastly, have a blessed new year and a great year ahead!

How Much Carbon Did The Indonesian Fire Emit?

Last month, palm oil concessions and small farmers in Indonesian began their annual land clearing and burning activity to open up new land for the new season, and the result was a devastating, month-long haze that blanketed neighboring Malaysia and Singapore.

Haze, as we know, is made up of dust particles, greenhouse gases, and carbon. Lots of carbon.

Are You A Super-Recognizer?

Most of us have had this awkward experience: met someone for the first time, shook hands, got to know his name, went to the lavatory, came back and poof! Oh hi have we met before?

How good are you in remembering, or recognizing faces?

Facial recognition is an important part of our lives, because without it we would probably have no friends. Even today, police still rely on facial composite sketched based on description by victims to identify potential suspect. Last month when I was travelling to China, the immigration officer took a hard, cold look at my face, and then at the photo in my passport, and asked me to reenact that smile I had in my passport.
Facial recognition, China-style.

Just a couple of months ago, Thai police launched a search for a young man in a yellow T-shirt, whom they believe blew up Bangkok's Erawan shrine on August 16. They had the CCTV footage of the suspect, but the quality was far from perfect. I've seen the snapshot of the footage: it's grainy, blur, and I could not even see his facial features. Worse, I would probably not recognize the suspect had he walked past me then and there.
Nonetheless, Thai police managed to arrest the suspect at the Cambodian border and said he matched the description of the yellow-shirted bomber in the footage.
But how can they be so sure?

Luckily for us, there are people who possess this seemingly unique ability to recognize faces. The Scotland Yard, for example, has formed a team of super-recognizers that specialize in recognizing faces, and one of their most important tasks is to sit in CCTV control centers to scan the crowd.

"Gary Collins is so good that he ID'd three people over his Sunday roast," says Detective Chief Inspector Mick Neville, speaking about one member of the super-recognizer team who likes to relax on weekends with an iPad loaded with photos of criminal suspects.

After London's 2011 riots, the super-recognizers combed through thousands of hours of footage, and Collins alone identified 190 faces among the rioters.

How hard can that be, you may ask.
Some of us have thousands of friends on Facebook and it's easy to remember all their names, right?

Well, we're not talking about recognizing the faces you're familiar withlike the faces of your friends and family–we're talking about recognizing the face of a stranger, a person whom you see for the very first time, say from two different photos laid side-by-side. Still don't think it's hard? You can take a simple test here, devised by Josh Davis, a psychologist at the University of Greenwich, to see how good you are at it. Note: I scored 11 out of 14. That's a B+.

However, the ability to recognize faces is not so rare. In fact, you might share this ability, too, and not even know it. According to David White of the University of New South Wales' forensic psychology laboratory, the ability to recognize faces, it seems, falls along a spectrum. At one end are the people who are "face-blind", also known as prosopagnosia, while the other end sit the super-recognizers. There are, however, fewer than 1 percent of people on this planet who falls into the super-recognizer end.

For the remaining 99%, hope is not all lost. There are, in fact, ways to improve your facial recognition skills. In a study published recently in Proceedings of the Royal Society B, White's team tested a group of crack forensic examiners who specialize in face image analysis to see whether they would perform better than average. These group of expert super-recognizers, it turned out, did perform better than either untrained students or forensic experts who don't match faces regularly. These elite group of specialists are so good they could even identify faces that were shown upside-down. This leads White to suggest that with training, super-recognizers could further enhance their skills beyond their natural abilities.

Graphene Boosts Battery Performance

Have you ever wondered why are we not having batteries that could last much longer?
Charging the phone is easy—just plug it in and let it sit for a while—but when you have to do it often enough, it gets rather irritating.
