Since 1996, corn containing a gene that allows it to create a protein that is toxic to certain insects yet is safe for human consumption has been grown in the United States.

Most of this genetically modified "Bt corn" has been used for animal feed or processed into corn meal, starch, or other products. Varieties of sweet corn (corn on the cob) have existed since the late 1990s, though relatively few acres have been planted related to the impact of marketing campaigns against it by activist groups. 

A new study doesn't rehash the well-documented safety issue and instead deals with the environmental aspects. It suggests that Bt sweet corn is better for the environment because it requires fewer pesticide applications than conventional corn.

James Rothman, Randy Schekman and Thomas Südhof have been awarded the 2013 Nobel Prize in Medicine for their work on how the cell organizes its transport system.

Disturbances in the control system for the transport and delivery of cellular molecules contribute to conditions such as neurological diseases, diabetes, and immunological disorders. The three US researchers received the award for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells.

In a world of over-diagnosis, virtually anything can be considered a mental disorder if you are willing to pay someone to give you therapy for it. Afraid of attractive women? You have Venustraphobia. Afraid of GMO foods? The name is in the works.  Body piercings. plastic surgery, eating couch cushions, every odd compulsion has someone saying clinically it's real.

Even in the fuzzy world of behavior, being an actual clinical diagnosis requires an evidence basis and most pop diagnosis addictions don't have that; it's just individual weirdness manifesting a compulsion. 

Healthcare workers' use of disposable gowns and gloves upon entering all patient rooms on an intensive care unit, versus only in rooms on standard isolation protocol, helped reduce patient acquisition of methicillin-resistant Staphylococcus aureus (MRSA) by approximately 40 percent, according to new research.

The study did not show statistically significant results for preventing patient acquisition of another common bacteria, vancomycin-resistant Enterococcus (VRE) and the use of gowns and gloves increased handwashing frequency among healthcare workers and did not result in any increase in adverse events for patients.  

Huge ice channels almost as tall as the  Eiffel tower have been discovered beneath a floating ice shelf in Antarctica. They are 250 meters high, stretch hundreds of kilometers along the ice shelf, and likely influence the stability of the ice shelf.

The scientists used satellite images and airborne radar measurements to reveal the channels under the ice shelf. The channels can be seen on the surface of the ice shelf, as well as underneath, because the ice floats at a different height depending on its thickness.  

Fumigation is important in reducing food waste.  Weevils, moths and borer beetles live in a very comfortable environment when in the middle of a silo or warehouse fill with grains, where they perforate the external layer of the stored products, feed freely, and have an ideal temperature and enough oxygen to grow and breed.

This insects, alongside some fungi, bacteria and viruses, cause annual loses of between four and ten percent of all the stored grains worldwide, mainly corn, wheat, sorghum, rice and beans.

The main fumigation technique and pest control inside warehouses and silos has been the use of chemical substances such as aluminum phosphide and methyl bromide, which are effective but leave a toxic residue for human consumption.
