4:59 AM | A New Twist on Flexagons?
For Martin Gardner’s 100th birthday Global Science source Martin Gardner introduced many including myself to the joys of Discrete Mathematics. His glorious monthly column “Mathematical Games” for Scientific American included some continuous mathematics too, of course; one could say it was on “Concrete Mathematics.” However, I conjecture—based on a quick flip of the several books […]

12:55 AM | Forecasters and Science Writers Knock Weather.Com For Hype
A low-end nor’easter is bringing wind and rain to much of the Northeast U.S. this evening, and Gale Warnings have been posted in the Atlantic as well. As nor’easters go, this is not really a big one, and we will see far worse over the coming months, with some of them bringing snow instead of rain.This is what I told my viewers here in Maryland/ Delaware, and so did many …

8:43 PM | 'I’m scared I’m going to die'
Axl Goode recently discovered that he was sitting only three seats away from Ebola patient Amber Vinson while flying from Cleveland to Dallas on October 13th. Here is his courageous story. The incessant buzzing of my cell phone woke me, text after text pouring in. Rolling over in bed, I saw that the messages were from my dad. Our text conversation was as follows: Dad, “2nd healthcare worker tests positive for Ebola...you know, the ones wearing hazmat suits.” […]

So this afternoon I was trying to go to the National Association of Science Writers website (that’s an org I’m a member of) and for some reason I went to sciencewriters.org instead (not their website, but wait until you see whose website it IS), and I was rewarded with THE BEST 90’s space/science GIF I’ve ever seen. What does it even mean though? UPDATE (thanks to spaceplasma): Here’s the background on that symbol. It relates to the late biologist Lynn […]

7:55 PM | How Goats Are Replacing Bulldozers and Pesticides In Invasive Plant Control
Since the mid-1970s, land owners in the U.S. and Canada have been fighting a losing battle against Phragmites australis, an invasive reed that grows in tall thick bundles in wetlands areas along the east coast. Not only do the reeds quickly take over by choking out native vegetation, but they also litter wetlands areas with thick mats of decaying biomass. Land managers have tried everything to get rid of the phragmites reeds: controlled burns, toxic pesticides and even […]

7:04 PM | This Is Not The Immigration Crisis You're Looking For
When is an immigration crisis not an immigration crisis? When people who do not live where it is happening change the definition of an immigration crisis. A new paper from Rice University's Baker Institute for Public Policy examines historical immigration data, the "push" and "pull" factors currently motivating Mexicans and Central Americans to migrate to the U.S. and then attempts to explain why current undocumented immigration streaming across the Mexican border is not a crisis. read more

Chris Kluwe on Gamergate: Dear #Gamergaters, Do you know why you piss me the fuck off? Because you’re lazy. You’re ignorant. You are a blithering collection of wannabe Wikipedia philosophers, drunk on your own buzzwords, incapable of forming an original thought. You display a lack of knowledge stunning in its scope, a fundamental disregard of history […]

5:29 PM | Olive, Corn, Soybean Or Sunflower Oil - The Science Answer As To What Is Best For Frying
Frying in oil is one of the world's most popular ways to prepare food — chicken and French-fried potatoes are staples but even candy bars and whole turkeys have joined the list of deep-friend goodness.  Lots of oil make health claims but there is a whole range of physical, chemical and nutritional properties that can degrade oil quality when heated so a paper in the Journal of Agricultural and Food Chemistry  tested four different refined oils — olive, corn, […]

Laser-powered weapons have been a staple of science-fiction movies for so long we think we know what they would look like, but we really don't. Researchers at the Laser Centre of the Institute of Physical Chemistry of the Polish Academy of Sciences and the Faculty of Physics, University of Warsaw decided to find out, and make a real film of it. They fired an ultrashort laser pulse through the air and captured it on video and when they slowed it down they found that it looks lot like a […]

3:41 PM | Protection from our own cells
Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body's natural defence against this 'friendly fire', scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, have found.

3:32 PM | Olive oil most healthful for frying food
Frying is one of the world's most popular ways to prepare food — think fried chicken and french fries. Even candy bars and whole turkeys have joined the list. But before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists report in ACS' Journal of Agricultural and Food Chemistry that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.

3:12 PM | Epidemiologists Link Air Pollution To Autism
Children with autism spectrum disorder, a range of conditions characterized by social deficits and communication difficulties, were more likely to have been exposed to higher levels of certain air toxics during their mothers' pregnancies and the first two years of life compared to children without the condition, according to preliminary findings presented today at the American Association for Aerosol Research annual meeting in Orlando. Other epidemiologists have linked everything from living […]

Hi sexy science readers! :)Did you know that smallpox was the first, and the only infectious disease of humans that has been completely eradicated through our medical advancements? The eradication of this disease was kick-started by Edward Jenner, who led the vaccine revolution…“Should I vaccinate my baby?”…But even then, there was resistance to the concept of vaccination, and this resistance still continues today. Indeed, there are lots of myths and misunderstandings […]
