Will This Be The End of Hamburger Disease?

Hamburger disease, a debilitating form of food poisoning, may be a thing of the past. New findings from an international research collaboration conducted by the French National Institute for Agronomic Research (INRA), involving the Université de Montréal are the first to show how the contaminating E.coli bacterium is able to survive in the competitive environment of a cow’s intestine by scavenging specific food sources. Published in this month’s Environmental Microbiology, and featured in Nature Reviews Microbiology, this study may lead to non-medicinal methods for eradicating this invasive bug.  (more…)

Spanish Woman Claims She Owns the Sun

Angeles Duran, 49-year-old Spanish lady has claimed to be the owner of Sun. Woman from Spain’s soggy region of Galicia said that she registered the star at a local notary public as being her property after learning about the American man, who registered moon and most planets in our solar system as his property.

Here is an international agreement, which states that no country may claim ownership of a planet or star, but it says nothing about individuals, she added.

“There was no snag, I backed my claim legally, I am not stupid, I know the law. I did it but anyone else could have done it, it simply occurred to me first,” she told the online edition of Spanish daily newspaper El Mundo. (more…)

Mammals Grew 1,000 Times Larger After the Demise of the Dinosaurs

NSF enabled the assembly of an international, interdisciplinary team that was the first to quantitatively document body size patterns over the past 100 million years

Researchers have demonstrated that the extinction of dinosaurs some 65 million years ago paved the way for mammals to get bigger, about a thousand times larger than they had been when dinosaurs roamed the earth. The study, released in the journal Science, is the first to quantitatively document the patterns of body size of mammals after the existence of dinosaurs. (more…)

How Pathogens Hijack Host Plants

Palo Alto, CA — Infestation by bacteria and other pathogens result in global crop losses of over $500 billion annually. A research team led by the Carnegie Institution’s Department of Plant Biology developed a novel trick for identifying how pathogens hijack plant nutrients to take over the organism. They discovered a novel family of pores that transport sugar out of the plant. Bacteria and fungi hijack the pores to access the plant sugar for food. The first goal of any pathogen is to access the host’s food supply to allow them to reproduce in large numbers. This is the first time scientists have a direct handle on controlling the food supply to pathogens and thus a new means to prevent a wide range of crop diseases and losses.  (more…)

Passive Smoking Kills 600,000 Every Year

More than 600,000 people, including 165,000 children, die every year from passive smoking, a report from World Health Organisation experts says today. The estimates from the first analysis of the true global toll are based on the best available data across 192 countries and the known effects of exposure.

The biggest impact on children is in the developing world. “Two-thirds of these deaths occur in Africa and south Asia,” the authors write in the medical journal The Lancet. “Children’s exposure to second-hand smoke most likely happens at home, according to The Guardian. (more…)

Russia to Restore Naval Presence in All Oceans

Russia may open new naval bases in other countries, President Dmitry Medvedev stated November 25 at a meeting with Russia’s top brass.

“Unfortunately, the reality is that a number of our previous opportunities have disappeared,” Medvedev said. Medvedev said that he now had “certain ideas” about how these could be replaced. “But for obvious reasons, I will not say them out loud,” he added.

First and foremost, it goes about support points for Russian vessels on the territory of foreign countries. It is necessary to build such objects to support Russia’s military presence in strategically important parts of the globe. (more…)

Earth’s Lakes Warming Due to Climate Change

WASHINGTON – In the first comprehensive global survey of temperature trends in major lakes, researchers have determined that Earth’s largest lakes have warmed during the past 25 years in response to climate change. 

Philipp Schneider and Simon Hook of NASA’s Jet Propulsion Laboratory in Pasadena, Calif., used satellite data to measure the surface temperatures of 167 large lakes worldwide. 

They reported an average warming rate of 0.45 degrees Celsius (0.81 degrees Fahrenheit) per decade, with some lakes warming as much as 1 degree Celsius (1.8 degrees Fahrenheit) per decade. The warming trend was global, and the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere.  (more…)

Why Do People Behave Badly? Maybe It’s Just Too Easy

Many people say they wouldn’t cheat on a test, lie on a job application or refuse to help a person in need. 

But what if the test answers fell into your lap and cheating didn’t require any work on your part? If you didn’t have to face the person who needed your help and refuse them? Would that change your behaviour?  (more…)
