- Housecats Susceptible to Wild Feline Disease
There are really two types of cats out there: the cute and cuddly house cat and the vicious predator wildcats. However, for bacteria and viruses, there is no difference. The domestic cats are equally vulnerable to the same diseases that afflict wild bobcats, cougars, and others. A new study led by Colorado State University found that all cats living in the same area share the same diseases. In fact, domestic cats can act as a bridge to spread feline diseases to human households.
- Slash-and-burn 'improves tropical forest biodiversity'
Slash-and-burn agricultural practices, banned by governments because of the risk of uncontrolled fires, provide better growing conditions for valuable new trees than more modern methods of forest clearance, a study suggests.
- Rare Moroccan Argan Oil – Now Made In Israel
Argan oil, rich in vitamin E and fatty acids, has become the sensation of the decade, sought after by chemists, dieticians, hair salons, chefs and cosmeticians. Until recently, it was a rare product grown only in the Atlas Mountains and traditionally made by Moroccan tribes, as the Argan tree could not grow outside of Morocco. Now, Israeli company Sivan is developing "Argan 100" – a super strain of Argan that is tolerant of the Mediterranean climate and can produce ten times more nuts than the average tree in Morocco, they say.
- Bahamas' Blue Holes harbor strange lifeforms
Clues to how life evolved, not only on this planet but also possibly on alien worlds, might be found in underwater caves in the Bahamas, researchers say.
The caves in question are called "blue holes," so-named because from the air, their entrances appear circular in shape, with different shades of blue water in and around them. There are estimated to be more than 1,000 such caves in the Bahamas, the greatest concentration of blue holes in the world.
- Rising ocean acidity worst for Caribbean and Pacific
The current trend of increasing ocean acidification, which threatens fisheries around the world, is driven mainly by man-made changes and is higher even than that seen at the end of the last ice age, some 11,000 year ago, a study has said. Much of the carbon released by human activity ends up in the oceans, increasing their acidity and reducing the growth of corals and molluscs, which in turn may affect fisheries and aquaculture.
- Dune Flows
Sand dunes flow over the land subject to the winds like ocean waves or rivers. What makes them move? What makes them start or stop? In a study at the White Sands National Monument in New Mexico, University of Pennsylvania researchers have uncovered a unifying mechanism to explain the beautiful dune patterns that occur. The findings may also hold implications for identifying when dune landscapes like those in Nebraska's Sand Hills may reach a tipping point under climate change, going from valuable grazing land to barren desert.
- The Future of Trucking is Electric
Trucking has become the most common mode for transporting goods across the land. However, all those trucks on the road burning diesel fuel can create a great deal of air pollution. Plus, higher gas prices cause increases in the prices of goods. Now is the time to consider the next era of trucking, the electric truck. At the moment, they cost about three times more than the internal combustion engine truck. However, a new study from the Massachusetts Institute of Technology (MIT) shows that a fleet of electric trucks can actually be more cost effective than the standard diesel fleet.
