Moose Drool Detoxifies Fungus
July 25, 2014 06:06 AM - Allison Winter, ENN
Saliva contains important substances helps us digest food. It also plays a part in keeping our mouths clean and healthy. Another newly discovered use? Making toxic plants less toxic. Not for us of course, but according to new research, moose and reindeer saliva can help can slow the growth of a toxic grass fungus, and subsequently make it less toxic for them, allowing the animals to graze on the grass without negative effects.
New research compares environmental costs of livestock-based foods
July 22, 2014 08:00 AM - Allison Winter, ENN
Trust me, no one loves a nice, big, juicy steak more than me and while I have no immediate plans of becoming a vegetarian, I am a little concerned about the resources and costs it takes to produce the proteins of our favorite meals. From the land that is used by livestock to the supplies and energy it takes to raise these animals for our consumption, it is evident that environmental resources take a toll. But what is the real cost? New research at the Weizmann Institute of Science, conducted in collaboration with scientists in the US, calculates these environmental costs and compares various animal proteins to give a multi-perspective picture of what resources are really being used.
Aura's Ten Year Mission Improves our Understanding of Ozone
July 17, 2014 06:57 AM - Allison Winter, ENN
This week, on July 15, NASA's Aura satellite celebrated its 10th anniversary. Happy belated, Aura! The mission of Aura, which is Latin for breeze, centers on obtaining measurements of ozone, aerosols and key gases throughout the atmosphere. And after one decade in space, the satellite has provided vital data about the cause, concentrations and impact of major air pollutants.
Rainwater discovered below the Earth's fractured upper crust
July 16, 2014 06:40 AM - Allison Winter, ENN
When it rains, where does the water go? Well for one, a lot of rainwater will funnel its way off roads and impermeable surfaces and will make its way into storm sewers. Another path might be directly into rivers and lakes. Or, rainwater might get soaked up by soil where it will then infiltrate into the ground and replenish aquifers. But just how deep does this rainwater infiltrate? According to new research, rainwater can penetrate below the Earth's fractured upper crust - which is at least eight miles below the Earth's surface!
Sand Power: A Better Battery
July 15, 2014 11:32 AM - Winfield Winter, ENN
Technology of the future is hard to see coming — sometimes because you can't see it. Advances in nanotechnology are the driving force behind longer lasting Lithium-ion batteries. Currently, Lithium-ion batteries are used to power every-day technologies like cell phones, computers, cameras and cars. Their energy source is a carbon-based graphite anode, which is nothing short of polarizing. Battery life has always been a major concern with Li-ion batteries. The solution is the most abundant compound in the earth's crust: SiO2, - or — more commonly — sand. The next generation of battery technology is using sand as a source for the production of nano-silicon, an anode material for Li-ion batteries.
Record Radiation in South America
July 11, 2014 09:00 AM - Winfield Winter, ENN
Astrobiologists from the United States and Germany recorded the highest known level of solar UV radiation to reach Earth's surface. This was around 10 years ago. On December 29, 2003, the UV Index (UVI) peaked, reaching the blistering number of 43.3 over the Andes Mountains in Bolivia. To put this in context, a beachgoer in the United States would expect a UVI of 8 or 9 on a summer day. Even with an 8 or a 9, one may not escape the day without sunburn. Nonetheless, it has taken scientists 10 years to detail a report of this data while taking into account all of the variables and anomalies monitored from an international network of dosimeters — or Eldonets (European Light Dosimeter Network) — that measure UV radiation worldwide. This system is comprised of more than 100 stations across 5 continents to account for variation in the atmosphere above each station.
SAR11 and Methane
July 8, 2014 08:07 AM - Allison Winter, ENN
With the focus on reducing carbon emissions, we often forget about methane — another greenhouse gas that is way more powerful as an atmospheric pollutant than carbon dioxide. Methane emissions can come from industry, agriculture, and waste management activities, but can also be emitted from a number of natural sources. One newly discovered natural source: SAR11.
Choosing the Right Path: How Air Travel Affects Climate Change
June 26, 2014 10:40 AM - Winfield Winter, ENN
It has been well documented that one negative of air travel — besides the food — is the emission of CO2 from jet engines. But what about contrails? Dr. Emma Irvine, Professor Keith Shine, and Professor Sir Brian Hoskins, at the Department of Meteorology at the University of Reading have linked contrails to global climate change in a study published in IOP Publishing’s journal Environmental Research Letters. According to their report, contrails may have a greater radiative forcing (the capacity for an agent to enact climate change via warming) than CO2.
The economic risks of climate change
June 24, 2014 12:38 PM - Rutgers University
New independent report identifies challenges facing U.S. businesses and policymakers; describes strategies to avoid significant, unequally-spread economic disruptions. The American economy faces major risks from climate change, including damaging coastal storms, growing heat-related mortality, and declining labor productivity, according to an independent report released today by business, education and political leaders.
New study challenges theory that emperor penguins return to same area each year
June 20, 2014 02:09 PM - Allison Winter, ENN
Philopatry is the tendency of an organism to stay in, or return to its home area. Many animal species are considered philopatric because they often return to their birthplace year after year to breed. Revisiting the same site is advantageous because nests and courtship areas have already been established while competition from other animals is largely non-existent due to territoriality. Researchers have long thought that emperor penguins were a prime example of this phenomenon, however a new study shows that this species may be adapting to changing environments and may not necessarily be faithful to previous nesting locations.
