Not all non-human animal dads are cut out for family life, but there are a number of species who have become known for their role as fathers who deserve a salute, from giant water bugs who carry dozens of eggs on their backs to males who actually get pregnant and dads who operate solo as single parents. This Father's Day, it's time to celebrate some of the amazing dads from the animal kingdom who go above and beyond when it comes raising and protecting their young.
Red Fox
Male red foxes aren't just loving mates, but excited and protective fathers. They take on the task of providing food for their mates every few hours for about a month after she gives birth. Then they take on the role of teacher – but teachers who like to take time out to play. Even when it’s time to get serious and teach their young how to start finding their own food, fox dads help them out and make sure they don't really go hungry by hiding it near their dens.

Tomorrow is Father's day and animals are not normally thought of as being good fathers. For most species, the mothers do most of the work feeding and nurturing their young. Owl monkeys appear to be an exception!
If there were a competition for "best father" in the animal kingdom, owl monkeys might very well win.
Why? Because father owl monkeys provide most of the care needed by their young--carrying them almost all the time, even when chased by predators. By contrast, caregiving from owl monkey mothers to their young is limited almost exclusively to nursing.
Considering the high prevalence of "deadbeat dads" and even "cannibal dads" in the animal kingdom, why--of all creatures--are father owl monkeys so attentive and protective of their young? This question is answered by Patricia C. Wright of Stony Brook University in the accompanying video.

NASA's first spacecraft dedicated to measuring carbon dioxide levels in Earth’s atmosphere is in final preparations for a July 1 launch from Vandenberg Air Force Base, California.
The Orbiting Carbon Observatory-2 (OCO-2) mission will provide a more complete, global picture of the human and natural sources of carbon dioxide, as well as their "sinks," the natural ocean and land processes by which carbon dioxide is pulled out of Earth’s atmosphere and stored.

While penguins have adapted to extremely cold weather, harsh winters are still difficult for populations especially when it comes to breeding and finding food. So with warming climates on the horizon, are penguin populations going to be better off? Not necessarily. However, a new study does reveal that penguin populations over the last 30,000 years have benefitted in some ways from climate warming and retreating ice. An international team, led by scientists from the University of Southampton and Oxford University, has used a genetic technique to estimate when current genetic diversity arose in penguins and to recreate past population sizes.

One of the world's most polluting industries is the textile-dyeing sector, which in China and other Asian nations releases trillions of liters of chemically tainted wastewater. But new waterless dyeing technologies, if adopted on a large scale, could sharply cut pollution from the clothing industry.
Each year, one global industry gulps down trillions of liters of fresh water, together with massive amounts of chemicals. The wastewater from that industry is then dumped, often untreated, into rivers that bring its toxic content to the sea, where it spreads around the globe.

The world's stronghold for Indian rhinos—the state of Assam—has seen its population leap by 27 percent since 2006, despite a worsening epidemic of poaching that has also seen 156 rhinos killed during the same period. According to a new white paper, the population of Indian rhinos in Assam hit 2,544 this year up from a nadir of around 200 animals in the early 1900s.

With summer temperatures fast approaching, households across the country are installing and prepping air conditioning units in anticipation of hot, sticky weather. However, a potentially brutal cycle may be in store if summertime extreme-heat days are projected to become more frequent and intense as a result of climate change. According to a new study conducted in Phoenix by Arizona State University researchers, so much wasted heat is emitted by air conditioning units that it actually raises the city's outdoor temperature at night by 1-2.7 degrees! Consequently, these warmer temperatures may encourage individuals to further their demands and energy use of their air conditioners. The research, published last month in the Journal of Geophysical Research, investigates the effects of air-conditioning systems on air temperature and examines their electricity consumption for a semiarid urban environment.

Using too much fertilizer is a very bad idea. It doesn't help crops, and in fact can be harmful to them. Excess fertilizer runs off and contributes to river and stream contamination and a new study shows that it is bad for the climate too!
But farmers sometimes think that if some is good, more MUST be better!
Helping farmers around the globe apply more precise amounts of fertilizer nitrogen is a great objective that can improve crop yields, reduce pollution, and combat climate change.
That's the conclusion of a study published this week in the journal Proceedings of the National Academy of Sciences. In the paper, researchers at Michigan State University (MSU) provide an improved prediction of nitrogen fertilizer's contribution to greenhouse gas emissions from agricultural fields.

While one may think that forest and lake ecosystems are two separate networks, new research shows how forest debris is an important contributor to freshwater food chains. How? Debris in the form of organic carbon from trees washes into freshwater lakes, which consequently supplements the diets of microscopic zooplankton and the fish that feed on them. Researchers at the University of Cambridge conducted a study at Daisy Lake in Ontario, Canadian by observing Yellow Perch fish from different parts of the water body with varying degrees of surrounding forest cover. Carbon from forest debris has a different elemental mass than carbon produced by algae in the aquatic food chain. By analyzing the young Perch that had been born that year, scientists were able to determine that at least 34% of the fish biomass comes from vegetation, increasing to 66% in areas surrounded by rich forest. Essentially, the more forest around the edge of the lake, the fatter the fish in that part of the lake were. Similarly, the sparser the forest leaves, the smaller the fish.
