9:03 AM | Cosmos — The View From Here
I have seen creeping into recent discussions of the TV show ‘Cosmos’ the idea that we scientists, because of our greater knowledge and understanding of how the natural world works, will somehow be intrinsically better when it comes to dealing with matters of ethics, politics or religion.  I beg to differ. read more

8:00 AM | Alcohol could have cognitive benefits – depending on your genes
The cognitive cost or benefit of booze depends on your genes, suggests a new study which uses a unique longitudinal data set.Inside the laboratory psychologists use a control group to isolate the effects of specific variables. But many important real world problems can't be captured in the lab. Ageing is a good example: if we want to know what predicts a healthy old age, running experiments is difficult, even if only for the reason that they take a lifetime to get the results. Questions about […]

5:08 AM | Kepler - Young Earth Creationist
In the latest episode of Cosmos we got some history regarding how science has tried to converge on the age of the Earth. With that, we also got another jab at religion. Why use yet another religious contrast from hundreds of years ago to show the awesome power of science now? Is there so little actual imagination in their Ship Of The Imagination?(1)Just like with the age of the Earth, it's hard to know for sure, we only know there is a range of choices and can narrow it down as we get more […]

3:30 AM | Condensed Matter Physics Pitches In To Help Quantum Gravity
Relativity says that spacetime is smooth, and only big things can warp it, in ways that are exactly known. Quantum theory says that the smallest parts of the universe are constantly fluctuating and dramatically uncertain. How can something be both smooth and fluctuating, both exact and uncertain? How, in other words, can we make a quantum theory of gravity? It's unknown. String theory and loop quantum gravity have tried, but a unified theory has remained out of reach.Enter – of all things […]

2:17 AM | It's A Bubble, Jim, But Not As We Know It
SensaBubble is a chrono-sensory mid-air display system that generates scented bubbles to deliver information to people using different senses. The bubble-based technology creates bubbles with a specified size and frequency, fills them with an opaque fog that is optionally scented, controls their route, tracks their location and projects an image onto them.read more

11:57 PM | Male Or Female? Once Upon A Time, It Was Less Clear
Man or woman? Male or female? Modern sociological woo about gender aside, in humans and other mammals, the difference between the sexes depends on one single element of the genome: the Y chromosome. It is present only in males, where the two sexual chromosomes are X and Y, whereas women have two X chromosomes. Thus, the Y is ultimately responsible for all the morphological and physiological differences between males and females.read more

11:53 PM | Scientists Discover A New Shape Using Rubber Bands
Cambridge, Mass. – April 23, 2014 – While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature. This made the researchers wonder: Were the three-dimensional structures they observed randomly occurring, or are there specific factors that control their formation? The scientists answered that question by performing experiments in which they […]

11:53 PM | Microbes Provide Insights Into Evolution Of Human Language
Big brains do not explain why only humans use sophisticated language, according to researchers who have discovered that even a species of pond life communicates by similar methods. Dr Thom Scott-Phillips of Durham University led research into Pseudomonas aeruginosa, a type of bacteria common in water and soil, which showed that they communicated in a way that was previously thought to be unique to humans and perhaps some other primates.read more

9:49 PM | estimating the influence of a tweet–now with 33% more causal inference!
Twitter is kind of a big deal. Not just out there in the world at large, but also in the research community, which loves the kind of structured metadata you can retrieve for every tweet. A lot of researchers rely heavily on twitter to model social networks, information propagation, persuasion, and all kinds of interesting […]

8:56 PM | Study Shows Aspirin Can Reduce Colorectal Cancer Risks For Those With Specific Gene
The humble aspirin may have just added another beneficial effect beyond its ability to ameliorate headaches and reduce the risk of heart attacks: lowering colon cancer risk among people with high levels of a specific type of gene. The extraordinary finding comes from a multi-institutional team that analyzed data and other material from two long-term studies involving nearly 128,000 participants. The researchers found that individuals whose colons have high levels of a specific gene product […]

8:55 PM | Study: Iron Consumption Can Increase Risk For Heart Disease
A new study from the Indiana University School of Public Health-Bloomington has bolstered the link between red meat consumption and heart disease by finding a strong association between heme iron, found only in meat, and potentially deadly coronary heart disease. The study found that heme iron consumption increased the risk for coronary heart disease by 57 percent, while no association was found between nonheme iron, which is in plant and other non-meat sources, and coronary heart disease.read

7:45 PM | Meteoroid Caught Free-Falling On Video ?
A meteor caught on film during its non-luminous free fall at terminal velocity ? Or an elaborate hoax ? Or something else ? I must admit that when I saw the video posted in the internet a few weeks ago I was intrigued, and operated a willful suppression of disbelief. The footage showed a free-falling black stone that really looked like a meteoroid, passing by the owner of the camera hanging on a parachute, on the skies of Norway. I wanted to believe!Above: sum of frames from the video shot by […]

4:00 PM | How To Do The Moonwalk
Walking around in the real world, as opposed to the uncluttered hallways of your school, requires flexible and adaptive fine-tuning of the basic alternating stepping pattern of our two legs. For animals to walk, central pattern generators (CPGs) must be modulated to allow different stride lengths in each leg or different swing heights to step … Continue reading →

2:07 PM | Liquid Spacetime - The Fluid Flow Of General Relativity?
Quantum mechanics is able to effectively explain three of the four fundamental forces of the Universe - electromagnetism, weak interaction and strong interaction - but it does not explain gravity, which is currently only accounted for by general relativity, which is classical physics. Identifying a plausible model of quantum gravity - a description of gravity within a quantum physics framework - is one of the major challenges physics is facing today. Despite many, many, many hypothetical models […]

1:56 PM | What Do You Do With 1 Million Feral Camels?
Feral camels in the Australian outback are reviled as pests. Yet they thrive, totaling some one million strong. How did they go from historic helper to overbearing invader? As usual, numbers make the difference.  The deserts of the Australian outback are a notoriously inhospitable environment where few species can survive - but camels can. The dromedary camel (Camelus dromedarius) prospers where others perish, eating 80% of native plant species and obtaining much of their water through […]

1:04 PM | Controlling Your Kids: Cut Up Their Food And They'll Calm Down
Modern Western parents spend a lot of time trying to figure out new ways for kids not to be kids and to force their behavior into narrow ranges. Then modern Western spend a lot of time filling out surveys saying they want their kids to be intelligent, creative and independent.  If you are a parent who wants to mollify the animalistic eating behavior of your child, don't give them a chicken drumstick, cut their food into little pieces for them. Yes, whole foods are causing bad […]

12:00 PM | There Are Two Reasons You Got Unfriended On Facebook
20 years ago, your parents knew there were two things you did not discuss with dinner guests. Your grandparents knew it, your great-grandparents knew it. 2,000 years ago people knew it. In 2014, we are so much smarter we no longer know it. Maybe some surveys will help. And so to help us out, two papers address the most pressing topic in popular culture -  how people feel about being un-friended on Facebook. Ironically, they found this out by surveying people on Twitter.read more
