A bone fragment from a French archaeological site has turned out to be a part of an early specialized bone tool used by a Neanderthal before the first modern humans appeared in Europe.

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.

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.
