Super Typhoon Usagi and its 150 MPH winds will be the strongest weather event this year. 

The radar on the Tropical Rainfall Measuring Mission (TRMM) satellite captured an image of Supertyphoon Usagi near the end of a 24-hour period in which Usagi intensified by 65 knots. This is more than twice the commonly used 30-knot threshold for defining rapid intensification. The TRMM data was used to create a 3-D image. The data was collected at 1035 UTC/6:35 a.m. EDT on Thursday, September 19, 2013, when Usagi was at category 3 on the Saffir-Simpson hurricane intensity scale.

In my previous article, we took a look at one of the signals generated by the 555 test circuit where the output pin (pin 3) is connected to ground (-) which is a simple series of very brief pulses.

This series of pulses can be used to generate a tone that can be used as an alarm or can be adjusted with a fair amount of precision such that it can be used to tune a musical instrument.

It is often the case that I get yelled at for being both too liberal and too conservative in the same week. It happens because the science under discussion violates the motivated reasoning of someone's political beliefs.  No conservative ever complains that the policy implication of a science issue is a conservative one, obviously, but you can bet left-wing people will, and vice-versa.

Like many other transgenic crops, Bt maize synthesises its own pesticide - a toxic protein produced in its leaves and stems, which kills pests in a matter of days.

It's perfect, except, as will eventually happen in all pest control instances, when insect populations develop resistance to the toxin.  That is why there are controls on how much Bt maize is in an area. To date, management strategies implemented to delay the evolution of resistance have been successful.

An idle brain is still doing important work and in the age of constant information overload, it’s a good idea to go offline on a regular basis, says Erik Fransén, a researcher from Stockholm's KTH Royal Institute of Technology.

Telomerase is an enzyme that is the hallmark of both aging and the uncontrolled cell division associated with cancer and in an effort to understand and control telomerase activity, researchers at The Wistar Institute have discovered a protein "motif," named TFLY, which is crucial to the function of telomerase.

Altering this motif disrupts telomerase function, they found, a fact that they believe will help them in their efforts to identify inhibitors of telomerase with potential cancer therapeutic properties. 

Calcium helps strengthen bones in people but it is also a critical nutrient for healthy tree growth and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain. 

A year ago I noted an alarming increase in celiac disease patients - it seemed to be afflicting a lot of rich, white, American women.

Outrage and scorn were delivered to my door; dozens of comments vilified me for saying it was not a real disease - which would have been fine, had I actually said that. Yet dwarfing those comments by hundreds were the anecdotal claims of people who had self-diagnosed themselves as celiac, at least until they discovered that since it was an actual life-threatening disease, they couldn't claim they had it, so they had reverted to being gluten sensitive, or even intolerant - vague and non-descriptive and requiring no pesky diagnosis.

Europeans may be slightly less anti-science than they are portrayed - at least when it comes to food.

Though American activists want the USA to be more like Europe and ban GMOs (except, oddly, in the food that organic meat ate), that is either not a policy that actual European consumers wanted, or they have become more educated since those laws were passed, or surveys lack controls too much to be worthwhile.

How to present in a simple way the spinorial space-time and the privileged space direction it generates? What is the fundamental difference between space-time spinors and the conventional description of space and time? What is the relevance for the analysis of WMAP and Planck data ?
