The First Women in Antarctica



In the spring of 1969, Terry Tickhill Terrell was 19 and an undergraduate chemistry major at Ohio State University, bored with her lab work and restless. She had never traveled more than 250 miles from the Barnesville, Ohio farm where she grew up.

One day, after reading an article in the school newspaper about a graduate student who had just returned from Antarctica, Terrell decided that that was where she wanted to go.

Buses to have GPS system in Mangalore

Fitting of Global Positioning System (GPS) equipment will be made mandatory for all the buses in the district, for regulating the speed of the buses, said Dakshina Kannada district deputy commissioner, V Ponnuraj.

As the GPS makes it possible to ascertain the speed of the buses, places through which they move etc., the authorities can exercise better control over them. The GPS was implemented in the past, but many buses are still to be provided with this system. Therefore, it has been decided to make it compulsory for all the buses moving in the district, he clarified.

Maps depict effect of climate change

The Victorian Government has released maps showing the possible effects of sea level rises on vulnerable coastal regions over the next 100 years.According to these maps some townships could become submerged during extreme storm events, as water levels rise over the next century. Portland, Port Fairy, Port Phillip, Barwon Heads, Tooradin and Seaspray regions are the most risk prone areas.The study reveals that the sea levels during extreme storms could rise anywhere between 80 centimetres and 1.4 metres, over the next century. The Environment Minister, Gavin Jennings said that the study is more accurate than a similar Commonwealth study released on the weekend. More detailed reports are expected to be released by next year.

'Eye in the sky' to monitor irrigation projects

With some states not fully utilising the Centrally-funded scheme to create irrigation facilities, Government has decided to assign the National Remote Sensing Center to monitor 50 projects using satellite imagery.The satellite imagery will be used to confirm the progress made by states in carrying out irrigation projects under the Accelerated Irrigation Benefit Programme (AIBP). The Water Resources Ministry and the Central Water Commission will also carry out field visits to monitor physical progress and financial performance of ongoing projects.Earlier also center had used remote sensing technology to monitor 53 projects. It had later provided the Ministry with assessments of 48 projects which had helped in pinpointing gaps in the network which lead to non-continuity of the network for irrigation delivery.

Sea Slime Killing U.S. Seabirds



Hundreds of birds are washing up on the shores of the U.S. Pacific Northwest coated with a foamy sea slime, scientists say.

The slime, which comes from algae blooms in the ocean, saps the waterproofing ability of the birds' feathers, experts say. Untold hundreds have died, succumbing to hypothermia or predators such as eagles.Nearly 500 of the slimed birds have been transported to the rescue center in Fairfield, California, which was specially built to care for coastal wildlife contaminated with oil. Many of the slime victims have been released.

J&K in Pak, Arunachal in China on Allianz website

A city court asked Delhi police to file a report on a complaint against industrialist and Rajya Sabha MP Rahul Bajaj over his group's partner company Allianz portraying Jammu and Kashmir and Arunachal Pradesh as part of Pakistan and China respectively on its website.The court then posted the matter for further hearing. Sanjay Sachdeva, a member of Delhi Pradesh National Panthers Party, and others have sought prosecution of Bajaj under charges of sedition on the ground that disfigurement of Indian map was an "anti-national" act.Responding to the allegations, Bajaj had earlier told that it was the portal of Bajaj's insurance venture partner, Allianz, that had carried the alleged map with the discrepancy."I have nothing to do with the case as it was Allianz which had put the map on its website. They have, in fact, corrected the discrepancy as soon as it was pointed out about a month back," Bajaj had said.

Floodgates Might Not Save Venice


The construction of mobile floodgates aims to safeguard the 1,300-year-old island city of Venice. It's an ambitious engineering project, but some scientists say it may not be sufficient to protect Venice from rising sea levels due to climate change.

Venice rose from mudflats in the middle of a lagoon which forms the largest wetland in the Mediterranean. One of the world's most endangered cities, it has been subject to increasing flooding due to sinking land — but also to rising sea levels.

It's known as "aqua alta" — high water — and it brings city life to a standstill for several hours. Big boats can't go under low-hanging bridges, and water seeps into buildings through the sewage system. Venetians have not lived on the ground floor for decades.

Did early humans evolve in Europe, not Africa?


Received wisdom that modern humans emerged in Africa then dispersed across the rest of the globe is being challenged by skulls found in Dmanisi, a site in Georgia to the south of Russia.Analysis of the skulls suggests that instead, small numbers of very early ancestors of modern-day humans may have migrated to Europe, where they evolved into Homo erectus, the immediate predecessor of modern Homo sapiens.Then, Homo erectus filed back into Africa before eventually making the crucial transition to Homo sapiens.

Seed variety loss seen hampering climate response


Farmers in developing countries are losing traditional varieties because of growing corporate control of the seeds they plant, hampering their ability to cope with climate change, a London-based think tank said on Monday.

The International Institute for Environment and Development (IIED) said in a report that the diversity of traditional seed varieties is falling fast and this means valuable traits such as drought and pest resistance could be lost forever.

The report was issued ahead of the World Seed Conference which opens on Tuesday at the United Nations Food and Agriculture Organization in Rome.

Signaling Pathway Ensures That Plants Remember To Flower


Why do some plants blossom even when days are short and gray?

Scientists at the Max Planck Institute for Developmental Biology have found the answer to this question: An endogenous mechanism allows them to flower in the absence of external influences such as long days. A small piece of RNA, a so-called microRNA, has a central role in this process, as a decline of its concentration in the shoot apex triggers flowering.

What Mars is Really Like!


NASA has released stunning photographs of the planet Mars. Taken by the Mars Reconnaissance Orbiter, the views are amazing! Some show the Victoria crater which has been explored close up by a rover vehicle for two years. Another shows a dust devil in the Martian atmosphere.

The new oblique view of Victoria Crater shows layers on steep crater walls, difficult to see from straight overhead, plus wheel tracks left by NASA's Mars Exploration Rover Opportunity between September 2006 and August 2008. The orbiter's High Resolution Imaging Science Experiment camera shot it at an angle comparable to looking at landscape from an airplane window. Some of the camera's earlier, less angled images of Victoria Crater aided the rover team in choosing safe routes for Opportunity and contributed to joint scientific studies.

Dysnomia:Moon of Eris


 Eris I Dysnomia, is the only known moon of the dwarf planet Eris. It was discovered in 2005 by Mike Brown and the laser guide star adaptive optics team at the W. M. Keck Observatory, and carried the provisional designation of S/2005 (2003 UB313) 1 until officially named Dysnomia (from the Ancient Greek word Δυσνομία meaning "lawlessness") after the daughter of the Greek goddess Eris.
Dysnomia is about 500 times fainter than Eris, and its diameter is estimated to be 100 to 250 km. The moon is likely too small to be spherical due to self gravity. Combining Keck and Hubble observations, the satellite was used to constrain the mass of Eris, and orbital parameters were estimated. Its orbital period is calculated to be 15.774±0.002 d.These observations indicate that Dysnomia orbits Eris at a distance of 37 370 ± 150 km. This suggests that the mass of the system is approximately 1.27 times that of Pluto.

Increasing Antarctic Sea Ice Extent Linked To Ozone Hole


Increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole, according to new research.Reporting in the journal Geophysical Research Letters, scientists from British Antarctic Survey (BAS) and NASA say that while there has been a dramatic loss of Arctic sea ice, Antarctic sea ice has increased by a small amount as a result of the ozone hole delaying the impact of greenhouse gas increases on the climate of the continent.

Sea ice plays a key role in the global environment – reflecting heat from the sun and providing a habitat for marine life. At both poles sea ice cover is at its minimum during summer. However, during the winter freeze in Antarctica this ice cover expands to an area roughly twice the size of Europe. Ranging in thickness from less than a metre to several metres, the ice insulates the warm ocean from the frigid atmosphere above. Satellite images show that since the 1970s the extent of Antarctic sea ice has increased at a rate of 100,000 square kilometres a decade.The new research helps explain why observed changes in the amount of sea-ice cover are so different in both polar regions.
