1:37 AM | Original Star Wars movie models revealed
Before the days of computer graphics, film industry model makers constructed incredibly detailed, hand-made spaceship models for science fiction films. These models helped shape our collective vision of the future, and continue to do so today. Here are 140 up-close photos of ship and vehicle models constructed by ILM for the Original Star Wars Trilogy (1977-1983). Subject:  Technology

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 …

12:48 AM | Removing the salt from fracking
The boom in oil and gas produced through hydraulic fracturing, or fracking, is seen as a boon for meeting U.S. energy needs. But one byproduct of the process is millions of gallons of water that's much saltier than seawater, after leaching salts from rocks deep below the surface. Subject:  Technology

12:13 AM | The autonomous Google car may never actually happen
A good technology demonstration so wows you with what the product can do that you might forget to ask about what it can't. Case in point: Google's self-driving car. There is a surprisingly long list of the things the car can't do, like avoid potholes or operate in heavy rain or snow. Yet a consensus has emerged among many technologists, policymakers, and journalists that Google has essentially solved—or is on the verge of solving—all of the major issues involved with […]

11:40 PM | Democratic Education: A New Way to Look at Teaching and Learning (Opinion Piece)
Seven-year-old Penelope Day needs both hands to pick up the power drill. Penelope is spending the week at a day camp run by Construction Kids, a Brooklyn-based program that offers building classes throughout the year for kids as young as 2 years old. It’s one of a new and immensely popular wave of programs trying to shift kids away from computer screens toward actual, hands-on activities. Like building things from scratch. Using, yes, real, working power tools. With help […]

11:39 PM | Drink Up, Baby Boomer: Alcohol Associated With Better Memory
A new study found that people ages 60 and older who do not have dementia benefit from light alcohol consumption; it has been associated with higher episodic memory, the ability to recall memories of events.  Moderate alcohol consumption was also linked with a larger volume in the hippocampus, a brain region critical for episodic memory. The relationship between light alcohol consumption and episodic memory goes away if hippocampal volume is factored in, providing new evidence that […]

Structure of Bisphenol A. Credit: Ian MusgraveBy Ian MusgraveBisphenol A is in the news again. A paper just published in the Public Library of Science with the alarming title of “Holding Thermal Receipt Paper and Eating Food after Using Hand Sanitizer Results in High Serum Bioactive and Urine Total Levels of Bisphenol A (BPA)” is bound to ratchet up anxiety levels about this chemical yet again. read more

11:00 PM | The Comets Of Beta Pictoris
Beta Pictoris is a young star, only about 20 million years old, located about 63 light-years from us. It is surrounded by a huge disc of material, a very active young planetary system where gas and dust are produced by the evaporation of comets and the collisions of asteroids.read more

10:31 PM | Cancer Mutations, Now With Faster Modeling
By sequencing the genomes of tumor cells, thousands of genetic mutations have been linked with cancer. Sifting through this deluge of information to figure out which of these mutations actually drive cancer growth has proven to be a tedious, time-consuming process but MIT researchers have now developed a new way to model the effects of these genetic mutations in mice. Their approach, based on the genome-editing technique clustered regularly interspaced short palindromic repeats (CRISPR) is much […]

10:31 PM | How Lymph Nodes Expand During Disease
A new paper finds that the same specialized immune cells that patrol the body and spot infections also trigger the expansion of the immune organs known as lymph nodes. The immune system defends the body from infections but can also spot and destroy cancer cells and lymph nodes are at the heart of this response, but it was unclear how they expand during disease.  Researchers  at Cancer Research UK's London Research Institute found that when a type of immune cell known as dendritic […]

10:18 PM | Titan glowing at dusk and dawn
New maps of Saturn's moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one. The pair of patches was spotted by a NASA-led international team of researchers investigating the chemical make-up of Titan's atmosphere. Subject:  Astronomy/Cosmology

9:25 PM | Hand Sanitizers Increase BPA Levels From Cash Register Receipts
Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage containers.  It is also used in thermal paper cash register receipts and a new paper finds that is cause for concern. BPA has not been found to be harmful by the Centers for Disease Control, they say levels from all sources is 1/1000th safe levels for the US, the EU and Canada, but it is controversial due to publicity by […]

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

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, […]
