Past winners have included research on remote-controlled whale snot retrieval and the physics of why you don't spill your coffee.
Research suggests that traditionally the Inuit ate any number of meats including seal whale caribou and fish.

#A Glue That Seals Heart Defectsnearly a decade ago Jeffrey Karp was playing around with a new biodegradable polymer he'd made.
The proposed expansion--roughly 2000 additional square miles--would encompass the largest upwelling site in North america better protecting the nutrient-rich waters that support everything from reefs and seabird colonies to endangered whales.
Like other platypuses it was probably a mostly aquatic mammal and would have lived in and around the freshwater pools in the forests that covered the Riversleigh area millions of years ago said Dr. Suzanne Hand of the University of New south wales a co-author of the study.

#Are North Atlantic right whales mating in the Gulf of Maine? Using data obtained during six years of regular aerial surveys
and genetics data collected by a consortium of research groups scientists have strengthened evidence pointing to the central Gulf of Maine as a mating ground for North Atlantic right whales according to a study recently published online in the journal Endangered
The North Atlantic right whale (Eubalaena glacialis) is one of the most endangered marine mammal species in the world
But until now there was little to indicate where these whales mated a big missing piece in the puzzle of their life history.
which right whales were present in the study area during 2002-2008. Individual animals were identified using a photo identification catalog maintained at the New england Aquarium that includes most of the adults in the population.
The resulting analyses showed that the animals seen included a higher proportion of reproductively successful animals than were present in other areas that these whales used seasonally.
The researchers further assumed a 12-month gestation period for North Atlantic right whales similar to that estimated for the closely-related southern right whale (Eubalaena australis) by the South african whale biologist Dr. Peter Best.
In fact since the study ended fewer right whales have been observed in the area during what would be the mating period.
We are still seeing right whales in the central Gulf of Maine just not in the same numbers.
Most of the North Atlantic right whale population spends the spring and summer on feeding grounds off the northeastern U s. and the Canadian Maritimes.
but current reproductive rates for North Atlantic right whales are much lower than those for the recovering populations of southern right whales.
Determining the right whale's conception period and mating grounds are important steps in learning about the factors that may be impairing reproduction.

#Mass strandings of pilot whales may not be driven by kinship, DNA profiles showbiologists since Aristotle have puzzled over the reasons for mass strandings of whales and dolphins in
which groups of up to several hundred individuals drive themselves up onto a beach apparently intentionally.
and often fatal beachings of otherwise healthy whales. One hypothesis regarding the reason for strandings is that care-giving behavior mediated largely by family relationships plays a critical role.
or a few whales because of sickness or disorientation triggers a chain reaction in which healthy individuals are drawn into the shallows in an effort to support their family members.
A recent study published in the Journal of Heredity questions this explanation using genetic data to describe the kinship of individual long-finned pilot whales involved in mass strandings in New zealand and Tasmania.
The largest of these strandings included more than 150 whales all of which died. The study found that stranded groups are not necessarily members of one extended family evidence that contradicts the hypothesis that stranding groups all descend from a single ancestral mother.
Long-finned pilot whales are the most common species to strand en masse and it has long been assumed this tendency was related to the species'social organization.
Previous studies have shown that pilot whales have a matrilineal social organization in which neither males nor females disperse from the group into
This group structure is also found in killer whales but is thought otherwise to be rare in mammals.
If kinship-based social dynamics were playing a critical role in these pilot whale strandings first we would expect to find that the individuals in a stranding event are in fact all related to each other.
which are inherited from both parents from 490 whales involved in 12 stranding events. Contrary to the hypothesis that stranding groups consist of whales descended from a single ancestral mother (the extended matriline hypothesis) multiple matrilines were found in the groups stranded together.
In some strandings the researchers assessed the spatial relationships of individual whales on the beach.
The position of each stranded whale was mapped to determine if individuals found near each other were related.
No correlation was found between location and kinship even when considering only the location of nursing calves and their mothers who were separated often widely
and juveniles had no identifiable mother among the other beached whales. Several scenarios could account for the lack of spatial cohesion including the disruption of social bonds among kin before the actual strandings commented Oremus.
In fact the separation of related whales might actually be a contributing causal factor in the strandings rather than simply a consequence.
The results of this study have important implications for rescue efforts aimed at refloating stranded whales.
To answer this question the researchers conclude that genetic samples are needed from all whales involved in strandings including from those individuals that do eventually make it back to sea.
#Whales streaming baleen tangles to trap fooddiving and plunging through the waves to feed some whales throw their jaws wide
and engulf colossal mouthfuls of fish-laden water while other species simply coast along with their mouths agape (ram
or skim feeding) yet both feeding styles rely on a remarkable substance in the whales'mouths to filter nutrition from the ocean:
and decided to find out more about how the flexible material filters whale-sized mouthfuls of water.
He publishes his discovery that baleen is a highly mobile material that tangles in flowing water to form the perfect net for trapping food particles at natural whale swimming speeds in The Journal of Experimental Biology.
Whales usually carry 300 of these structures on each side of their mouths#arranged perpendicular to the direction of water flowing into the mouth
In addition the baleen fringes of the skim-feeding bowhead whale's bristles are twice as long as the lunging humpback's. Having obtained baleen samples from the body of a stranded humpback during graduate work at the New england Aquarium
and collected samples from ram-feeding bowheads in Alaska Werth began to compare how well the baleen trapped minute latex beads carried in flowing water.
First he tested a small section of each type of baleen in a flow tank as he varied the flow speed from 10 to 120 cm/s
which corresponds exactly with the swimming speed of bowhead whales skimming through shoals of copepods. However when he compared the porosity of the baleen of both species he was surprised by the similarity of the performances despite the whales'different feeding styles.
Having found that baleen filters best at the natural swimming speed of skim-feeding bowheads Werth is keen to scale up
and investigate how full-sized 4 m long baleen plates performstory Source: The above story is provided based on materials by The Journal of Experimental Biology.

#Researchers discover rare new species of deep-diving whaleresearchers have identified a new species of mysterious beaked whale based on the study of seven animals stranded on remote tropical islands in the Indian and Pacific oceans
Beaked whales a widespread but little-known family of toothed whales distantly related to sperm whales are found in deep ocean waters beyond the edge of the continental shelf throughout the world's oceans.
On 26 january 1963 a 4. 5 metre-long blue-grey beaked whale washed up at Ratmalana near Colombo.
Now it turns out that Deraniyagala was right regarding the uniqueness of the whale he identified.
While it is closely related to the ginkgo-toothed beaked whale it is definitely not the same species says Dr Dalebout.
For the others they drilled the bones of the whales in order to analyse short fragments of'ancient DNA'relying on techniques commonly used with old sub-fossil material from extinct species. The researchers also studied all other known beaked whale species to confirm the distinctiveness of Deraniyagala's whale
including six specimens of the closely related gingko-toothed beaked whale. A number of species in this group are known from only a handful of animals
and we are still finding new ones so the situation with Deraniyagala's whale is not that unusual Dr Dalebout says.
For example the ginkgo-toothed beaked whale first described in 1963 is known only from about 30 strandings
and has never been seen alive at sea with any certainty. It's always incredible to me to realise how little we really do know about life in the oceans.
Over the last 10 years or so two other new beaked whales have come to light; both through research in which Dr Dalebout was involved.
In 2002 Mesoplodon perrini or Perrin's beaked whale was described from the eastern North Pacific and in 2003 Mesoplodon traversii the spade-toothed whale was described from the Southern Ocean.
Both species are known from only about five animals each. With the re-discovery of Mesoplodon hotaula there are now 22 recognised species of beaked whales.

#Oceanographer examines pollutants in Antarctic seal milkan oceanographer from the University of Rhode island is analyzing the milk from Antarctic fur seals to determine the type
and quantity of pollutants the seals are accumulating and passing on to their pups. Rainer Lohmann a professor at the URI Graduate school of Oceanography is collaborating with a researcher at the Southwest Fisheries science Center in California to learn about the health and ecology of fur seals that winter in different locations in the South Pacific.
What we're trying to learn is where the pollutants come from and how those pollutants vary by where the seals feed said Lohmann who has conducted studies of marine pollutants around the world.
Fur seals that have given birth have lower pollutant levels than those that have not because they pass their pollutants on to their pups in their milk.
All of the seals the researchers are studying breed on the South Shetland islands of Antarctica but some spend the winter off the coast of Argentina while others winter off Chile.
The two groups are thought to be exposed to different pollutants in the food they eat at their wintering grounds.
According to Lohmann seal milk is about 50 percent fat enabling young seals to grow rapidly.
And due to the pups'smaller size the researchers speculate that the young seals are effected more seriously by the pollutants than are older and larger seals.
The seals can't avoid the pollutants so the best we can hope for is that the concentration of pollutants will decrease in their system over time
