  • Red-legged frogs are listed as threatened under the Endangered Species Act.
  • Gary Kittleson a biologist is trying determine whether the conservation efforts are helping or not.
  • Many steps have been taken to find  the frogs and conserve them.

In the east of swamp in Santa cruz , Califorina,  Gary Kittleson a biologist and young explorer is trying find the rare red legged frogs. A local trust has hired him, to determine whether their number is growing or decreasing.

The Area called Watsonville Slough is a important habitat for the red legged frogs.

These frogs lost their habitat due to over hunting for frog legs and development, and now it is listed as threatened under the Endangered Species Act.

Kittleson says it is not a job to spot frog in thick brush and pick out their sound and differentiate from other frogs. The people who have untrained ears wouldn’t able to do it. But Gary is an expert and is capable listing to them even while talking.

But this method is an old way of counting animals and it requires lot of time and man power too. With just Kittleson one could get only a small size of data because he can’t be there the whole time.

Hence the local trust of Santa Cruz has also partnered with Conservation Metrics a company which specialises in protecting and conserving biological matters. The company and Kittleson have setup song meters – little green boxes with microphones that record all night and capture everything.

Data recorded in the song meter is then uploaded in computer and the company employees little green boxes with microphones that record all night and capture everything.  What would normally take a whole team of field biologists can now be done by one person and a computer says Matthew Mckown CEO of Conservation Metrics.

“Our whole point is to make conservation better, so we are trying to make it as cheap as possible,” he says.

Conservation Metrics was found three years ago. Mckown believes big data is the hot tool in conservation to study endangered animals and threatened habitats.

“What you’re going to start having is cameras, acoustic sensors, satellites trained on these important parts of the world,” he says.

Kittleson stays in the Watsonville Slough where night has fallen and he finally spots one and says “Beautiful. Adult red-legged frog,”

He is not too optimistic about the future of the red legged frogs. But he says good data is the only way to know if conservation efforts are helping.

Thanksgiving Day. The name stands for itself as the day to give thanks and is celebrated as a national holiday in many countries like United States of America, Canada, Netherlands, Philippines, Grenada, Liberia while similarly named festival exists in Germany, Japan, and United Kingdom.
Thanksgiving holiday remains a day to give thanks at the close of the harvest season.

America
The official date for the American Thanksgiving that exists today was set by President Roosevelt to be on the fourth Thursday in November instead of the last Thursday in November as decided by President Lincoln as thanksgiving date.
But their thanksgiving is surrounded by a debate over the nation’s first celebrations and the two places embroiled in this debate are New England and Virginia as both the places provide certain proofs of being the spot for nation’s first celebrations for Thanksgiving.

Canada
Canadian Thanksgiving tradition is celebrated in the true spirit of giving thanks at the close of the harvest season. It is believed that due to the geographical differences from the USA, Canada’s Thanksgiving arrives on the second Monday in October as that is the close of their harvest season.

But in countries like Liberia, Netherlands, and Grenada, it is not just a day to give thanks at the close of the harvest season.

Liberia
In Liberia, Thanksgiving holiday is celebrated to mark the freedom from black slavery by the U.S.A. The Thanksgiving day’s date remains on the first Thursday of November and has been a tradition since 1820.

Netherlands
Netherlands celebrate thanksgiving to mark to commemorate the Pilgrims who had migrated and became residents of the city of Leiden and died at Pieterskerk. To commemorate the hospitality, the thanksgiving, a non-denominational Thanksgiving Day is celebrated as the same as American Thanksgiving Day’s morning.

But there are some countries like the Philippines where the tradition of Thanksgiving only arrived with the Americans due to it being an American colony in the early 20th century but the tradition of Thanksgiving there had seemed to die down.

Food:
The American Thanksgiving seems to dominate the Thanksgiving menu when it comes to this holiday. Their famous turkey, stuffing, cranberry sauce, gravy, pies, mashed potatoes, and yams are signature dishes related to this day.

Black Friday:
Not only food, American Thanksgiving has also made Black Friday, an informal day following the Thanksgiving Day to mark the beginning of their country’s Christmas season sales and it has been in the history books since 1952 such that it has become a tradition of its own now.

Thanksgiving Day remains an occasion for many families to get back together and celebrate this holiday in the spirit of one while giving the rise to the excitement of upcoming Christmas also which remains barely a month away from Thanksgiving day.

  • Indulging in smoking or drinking alcohol may not only damage your teeth but also lead to increased incidences of failure in dental fillings, warned researchers.

The findings, led by researchers from the University of Pittsburgh, showed that within two years of the dental procedure, Dental fillings failed more often in patients who drank alcohol, while the overall filling failure rate was higher in men who smoked.

Furthermore, people with a difference in the gene for matrix metalloproteinase (MMP2) — an enzyme found in teeth — were at increased risk of Dental filling failure.

This could be because MMP2 might be able to degrade the bond between the filling and the tooth surface, potentially leading to failure, the researchers said.

The results, published in the journal Frontiers in Medicine, suggest that genetic analysis might help dentists to personalize treatments for their patients, which could lead to improved outcomes.

“A better understanding of individual susceptibility to dental disease and variation in treatment outcomes will allow the dental field to move forward,” said Alexandre Vieira, a researcher from the varsity.

“In the future, genetic information may be used to personalize dental treatments and enhance treatment outcomes,” Vieira added.

For the study, the team from America and Brazil analyzed dental records of 807 patients.
Fillings can fail for a variety of reasons, including re-emergence of the initial tooth decay or the filling becoming detached.

The researchers also examined if newer composite resin Dental fillings are as durable as traditional amalgam fillings, which have been in use for more than 150 years but which contain mercury, a toxic metal.

The researchers found that overall, there were no major differences between patients receiving amalgam or composite Dental fillings in terms of filling failure rates. (IANS)

California, October 17, 2017 : California Governor Jerry Brown has signed a state senate bill, allowing a gender-neutral marker on birth certificates and driver’s licenses starting from 2019.

California thus became the first state in the US to allow a “nonbinary” gender to be marked on birth certificates, Xinhua news agency reported.

The so-called “nonbinary” gender means not exclusively male or female or a combination of two or more “genders.”

According to the Gender Recognition Act approved on Sunday, California will offer a gender-neutral option on state documents for those who are transgender, intersex and others who are not identified as male or female.

The law, published on the government official website, also made it easier for people to change their gender identity on official documents.

“Existing law authorises a person who was born in this state and who has undergone clinically appropriate treatment for the purpose of gender transition to obtain a new birth certificate from the State Registrar,” the bill read.

The Golden State is now also the second state in the US to allow residents to be identified by a gender marker other than “F” or “M” on their driver’s license.

Oregon and the District of Columbia had earlier issued the gender-neutral option on their driver’s licenses.
