Polar bears circling Arctic outpost of Russian scientists

Polar bears circling Arctic outpost of Russian scientists

A team of five Russian researchers shared that their outpost on Troynoy Island is being surrounded by around 10 adult polar bears and their cubs. In this situation, it is not safe for them to leave the outpost.

The researchers said that a female polar bear spends nights outside the station. In fact, the team no more has flares with them and polar bears have also killed one of their dogs. It has become quite difficult for them to perform meteorological observations.

Dolphins’ pattern of communication not so different from the way humans communicate: Study

Dolphins’ pattern of communication not so different from the way humans communicate: Study

For the first time, researchers have recorded a conversation between dolphins. Study researchers noticed the same after recording the conversation between two adult Black Sea bottlenose dolphins, named Yasha and Yana.

The dolphins did not interrupt each other during the conversation and took a pause to listen to each other. Researchers said that the pattern of communication was not different from the way modern humans talk to one another.

Bats waggle head and wiggle ears to keep track on prey with incredible precision

Bats waggle head and wiggle ears to keep track on prey with incredible precision

A PLOS Biology-published research paper has unveiled that bats also do head tilts as it help them track their prey with great level of precision. As per the researchers, bats use the head-tilts to enhance existing sensory awareness.

In the study, Melville Wohlgemuth at the University of Maryland along with team members has used recording devices to keep a tab on three big brown bats. Main focus of the research team was to notice when bats waggled their heads and wiggled their ears.

Hair Protein-based identification could be used as biological evidence instead of DNA profiling in future

Hair Protein-based identification could be used as biological evidence instead of DNA profiling in future

Researchers have high hopes from a new method that analyzes genetic mutations in proteins in human hair to act as a forensic technique other than DNA profiling. The method as per the US Energy Department scientists could perfectly match biological evidence to a single person.

The research team from Lawrence Livermore National Laboratory in California has found 185 protein markers in an examination of male and female hair samples from 66 European Americans, five African Americans, five ¬Kenyans and six remains taken from cemeteries dating from the 1750s to 1850s.

Humpback whales off the endangered category in the latest review

Humpback whales off the endangered category in the latest review

Endangered since 1970, US humpback whale population has bounced back and is no longer in the list of endangered species, unveiled federal authorities. Out of 14 different populations of humpback whales, nine have been removed from the endangered list of species.

Scientists name a Parasite after President Barack Obama

Scientists name a Parasite after President Barack Obama

A new species of parasitic flatworm that infects turtles in Malaysia is so rare and distinct that researchers had to name a new genus to incorporate it. The species has been named in honor of President Barack Obama and is known as Baracktrema obamai.

It is the first time that researchers had to take such a step for this group of parasites in the 21 years. As per study researchers, these turtle parasites are likely ancestors of the parasitic flatworms that results into human disease known as schistosomiasis.

Alarming decline in wilderness areas, immediate international attention needed

Alarming decline in wilderness areas, immediate international attention needed

Wildlife Conservation Society (WCS) today unveiled about shocking reduction in the wilderness areas across the world over the last two decades. Humans have been held responsible for destroying a tenth of earth’s wilderness in the above mentioned time period. If the same trend continues, researchers fear there would be no such area left within a century. The researchers were shocked to find out that a vast area around the size of two-times Alaska has been completely destroyed between 1993 and today by human activities.

Climate change results into Hawaiian forest birds’ die-offs

Climate change results into Hawaiian forest birds’ die-offs

A journal Science Advances-published research paper has provided yet another evidence of how climate change is altering earth. Study researchers have found that a drop has come in the population of native forest birds on the Hawaiian island of Kauai. They also face the threat of extinction because of climate change.

The climate change is heating the birds’ habitat and allows thriving and spread of mosquito-borne diseases. Global warming increases temperature resulting into the spread of diseases like avian malaria in wooded areas.

Judge asks FWS to extend critical habitat for lynx in Idaho, Montana and Colorado

Judge asks FWS to extend critical habitat for lynx in Idaho, Montana and Colorado

The US wildlife managers have been asked to extend habitat protections for the Canada lynx in Idaho, Montana and Colorado. In 2000, the Canada lynx, a rare wild cat found roaming the Rockies and mountain forests of other states, was listed as threatened under the US Endangered Species Act.

China’s efforts bring back giant panda from brink of extinction

China’s efforts bring back giant panda from brink of extinction

Chinese conservation efforts have brought back giant panda from the verge of extinction. China’s national icon has been taken off from the endangered list, an effort that China has been making for past many years.

There was a time when the giant panda was present across southern and eastern China. But owing to expansion of human population and development, these bears are now only present in areas where bamboo forests are present.
