3:01 PM | How To Save Formula 1
With the season newly underway, Formula 1’s struggles are already clear to see. The exorbitant costs of competing, combined with uneven profits is especially hurting the chances of survival for smaller teams. In fact, with only ten teams on the grid – down from 20 in 1989 – 2015 risks being remembered as one of the least contented F1 championships of history. read more

10:56 AM | We Already Have Pi Day, But Why Not 60 Seconds for Euler?
Fareed Zakaria of CNN has a very good piece in the Washington Post about STEM and I must say that it makes a lot of sense, although you might not think I would from the title. Check out “Why America’s obsession with STEM education is dangerous” and then come back here for more. Ok, so your back and I hope you agree with what he said, because I do, and …

9:00 AM | The Last Word
March 23 – 27, 2015 “How often do you get to document natural selection happening in a free-ranging population on such a short time scale? How many scientific studies look for that and don’t find it?” Guest poster Judith Lewis Mernit tells us about some very interesting bobcats. In medicine, the word “decompensate” does not mean […]

6:00 AM | The Clocks Go Forward Tomorrow and This is Why
Every autumn we smile at the thought of an extra hour of sleep as the clocks ‘fall back’, and every spring we sigh when we lose an hour as the clocks ‘spring forward’. It is that depressing time of year again as the clocks will, once again, be going forward in the early hours of [...] The post The Clocks Go Forward Tomorrow and This is Why appeared first on HeadStuff.

1:55 AM | Argentinian woman’s exorcism is stock behavior, unimpressive
I find absolutely NOTHING remarkable about this “exorcism” video. Yet several sites are claiming it is convincing. Frankly, there is nothing in this video that most people could not recreate with ease. The display, in fact, is more evidence against “possession” being a mimicked behavior based on what we think demon possession should look like.… Source: Doubtful News Related posts:Exorcism: It’s hot in Poland Exorcism “truth” not facts, says […]

1:41 AM | Hydrolyzed Fish Fertilizer - Nitrogen Source, Still Meets Organic Definition
In the production of organic vegetables, nitrogen is important, yet can be quite costly to manage. Nitrogen management is even more challenging when production practices call for the use of polyethylene mulch combined with fertigation. The authors of a new study published in HortScience have found that hydrolyzed fish fertilizer holds promise as an "economically feasible" nitrogen source for growing organic vegetables.read more

12:22 AM | Saved By The Bell makes for some uncomfortable truths regarding what society needs versus what it ultimately wants
A couple of weeks ago, Kelly Kapowski, Jessica Spano, Albert-Clifford Slater, Mr. Richard Belding and the 5-dimensional trickster-God known as Zachary Morris were born again on the set of The Tonight Show with Jimmy Fallon. Fans marvelled as the ageless heroes of Bayside High (most of them anyway) seemed to slip back into their roles [...] The post Saved By The Bell makes for some uncomfortable truths regarding what society needs versus what it ultimately wants appeared first on HeadStuff.

10:22 PM | What’s gnawing on Jane Austen’s hair?
The years hadn’t been kind to the lonely lock of Jane Austen’s hair on display in a Hampshire museum. Light had bleached it to a straw color; only the shadowed underside remained its original brown. A few tiny flakes of … Continue reading →

Sometimes I think I am really lucky to have grown convinced that the Standard Model will not be broken by LHC results. It gives me peace of mind, detachment, and the opportunity to look at every new result found in disagreement with predictions with the right spirit - the "what's wrong with it ?" attitude that every physicist should have in his or her genes. read more

8:04 PM | Still more evidence for groundwater on Mars
Monica Pondrelli and colleagues investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability. On the plateau, ELDs consist of rare mounds, flat-lying deposits, and cross-bedded dune fields. Pondrelli and colleagues interpret the mounds as smaller spring deposits, the flat-lying deposits as playa, and the cross-bedded dune fields as aeolian. They write that groundwater fluctuations appear to be […]

7:09 PM | Damselfly War Games - Aerial Sparring And Wing Coloration
Before a male damselfly hot-headedly enters into a duel of aerial sparring, it first works out its strategy. It gives its opponent's wings a once-over to assess its strength, knowing that more transparent wings and larger red spots generally show a stronger rival. Those who then decide to engage in long fights either try to wear their opponent down, or dazzle them with brilliant aerial moves that are too hard to follow. These damselfly war game strategies are set out in a study published in […]

4:21 PM | Drinking Raw Milk Dramatically Increases Risk For Foodborne Illness, Analysis Finds
An analysis conducted by researchers at the Johns Hopkins Center for a Livable Future (CLF) found that the risks of drinking raw (unpasteurized) cow's milk are significant. Consumers are nearly 100 times more likely to get foodborne illness from drinking raw milk than they are from drinking pasteurized milk. In fact, the researchers determined that raw milk was associated with over half of all milk-related foodborne illness, even though only an estimated 3.5% of the U.S. population consumes raw […]
