Yawn Contagion in Wolves
August 27, 2014 04:15 PM - Editor, ENN
A yawn is defined as a reflex act of opening one's mouth and inhaling deeply. We yawn most often when we are tired or when we're bored. But we also always yawn when we see someone else doing it. Why? People say we can't help it - it's contagious! But what really triggers this involuntary tendency? According to studies, yawning when others do is a sign of empathy and a form of social bonding. And believe it or not, we're not the only species to exhibit these contagious behaviors. A new study published today in the journal PLOS ONE shows that wolves may also be susceptible to yawn contagion.
Africa Faces Unsustainable Levels of Ivory Poaching
August 20, 2014 06:27 AM - Allison Winter, ENN
When it comes to illegal wildlife trade, one thing has always puzzled me ... Why is the demand for ivory so high? While I may not come across the black-market demands or understand the cultural or historical needs for these rare animal teeth, one thing is easy to see - populations of the African elephant are declining.
New Satellite To Help Farmers Facing Drought
August 19, 2014 09:08 AM - Allison Winter, ENN
Satellites are put into orbit for a variety of tasks. From sending television signals to our homes to enabling GPS devices, to helping us see weather on a global scale, satellites collect information and provide us with modern conveniences. One new use for a proposed satellite scheduled to launch this winter is soil moisture monitoring at a local level.
Origami in Space
August 16, 2014 09:30 AM - Winfield Winter, ENN
An ancient art form is beginning to take off in a way no one thought possible: on a spaceship. Origami, or Japanese folding paper, is currently being developed into solar panels at NASA's Jet Propulsion Laboratory at The California Institute of Technology. Solar panels that have endless applications. Space travel has already turned over the possibility of solar-powered flight via folding panels, but this particular reincarnation is different. Developers cite a more intricate fold that allows for efficient deployment of the solar arrays. And it doesn’t stop there. Origami may one day be used in self-assembling solar arrays that are launched into space to power the earth below.
Marine noise impacts eels too!
August 7, 2014 08:45 AM - Roger Greenway, ENN
Marine noise has been studied for it's impact on whales, dolphins and other marine animals. Might it also impact smaller creatures too? Eels, for example. Despite their reputation as slippery customers, a new study has shown that eels are losing the fight to survive when faced with marine noise pollution such as that of passing ships. Scientists from the Universities of Exeter and Bristol found that fish exposed to playback of ship noise lose crucial responses to predator threats. The study, published today in the journal Global Change Biology, found European eels were 50 per cent less likely to respond to an ambush from a predator, while those that did had 25 per cent slower reaction times. Those that were pursued by a predator were caught more than twice as quickly when exposed to the noise.
The Danger of Solar "Super-Storms"
August 5, 2014 01:45 PM - Winfield Winter, ENN
Watch out George Lucas fans, a Death Star may be in our horizons — and one would only have to look as far as our nearest stellar neighbor: the Sun. According to Mr. Ashley Dale of the University of Bristol, solar "super-storms" pose an imminent threat to the earth by disabling electricity and communication system — or worse. Thus, the celestial body that illuminates the world may very well be responsible for sending it into darkness. In this month's issue of PhysicsWorld, Mr. Dale writes: "Without power, people would struggle to fuel their cars at petrol stations, get money from cash dispensers or pay online. Water and sewage systems would be affected too, meaning that health epidemics in urbanized areas would quickly take a grip, with diseases behind centuries ago soon returning."
Nesting Implications for the Northern Gulf Loggerhead
July 31, 2014 10:29 AM - Allison Winter, ENN
After the Deepwater Horizon oil spill in the Gulf of Mexico in 2010, a massive response to protect beaches, wetlands, and wildlife occurred. Nonetheless, because of the spill, extensive damage to marine and wildlife habitats were reported and many studies have been conducted to quantify the affects of the oil spill on specific species. One study in particular which started in the wake of the spill looks at the nesting of loggerhead sea turtles in the northern Gulf and how their feeding areas have been not only affected by the Deepwater Horizon spill, but by commercial fishing operations, and areas used for oil and gas extraction.
Deep-Sea Octopus' Egg-Brooding Period Breaks Record!
July 30, 2014 04:55 PM - Allison Winter, ENN
Robins sit on their eggs for about two weeks after they are laid. Male seahorses usually carry eggs for 9 to 45 days. Deep-sea octopuses? Four and a half years! Researchers at the Monterey Bay Aquarium Research Institute (MBARI) have observed this unique brooding phenomenon and have declares this species to have a longer brooding time than any other known animal. Egg brooding happens after the parent species lays the eggs. The parents then do everything in their power to protect those eggs so that offspring can develop. This includes cleaning the eggs and guarding them from predators, which evidently risks the parents' own ability to survive. In May 2007, during a deep-sea survey, researchers from MBARI, led by Bruce Robison, discovered a female octopus (Graneledone boreopacifica), clinging to a rocky ledge just above the floor of the canyon, about 1,400 meters (4,600 feet) below the ocean surface. Over the next four and one-half years, the researchers dove at this same site 18 times.
Moose Drool Detoxifies Fungus

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.
