Similar topography of Antarctica and Mars may shed light on climate change on the Red Planet

Washington, August 29 : Using the latest high-resolution images and technology from satellites orbiting Mars, scientists have observed that parallels exist between Antarctica’s McMurdo Dry Valleys and the Red Planet’s gullies, which may shed light on climate change on Mars.

On Mars, the gullies appear to originate from cirque-like features high on pole-facing crater-interior walls, especially those within the Newton crater, 40 degrees South, examined for the study.

In addition to the cirque-like features, the evidence cited for former glaciation includes bowl-shaped depressions fringed by lobate, viscous-flow deposits that extend well out onto the crater floor.

Scientists find solution to remove scourge of arsenic poisoning in South Asia

Washington, August 29 : Researchers at the Queen’s University Belfast have come up with a solution to the world’s worst case of ongoing mass poisoning by creating a new low-cost technology to provide arsenic-free water to millions of people in South Asia, who are currently exposed to high levels of the poison in groundwater.

Currently, over 70 million people in Eastern India and Bangladesh, experience involuntary arsenic exposure from consuming water and rice; the main staple food in the region.

This includes farmers who have to use contaminated groundwater from minor irrigation schemes.

Indian-origin researcher’s new microwave cookware halves rice cooking time

Washington, August 29 : An Indian-origin professor of clay mineralogy at Pennsylvania State University has made a new cookware that interacts with microwaves to generate heat, and cooks rice in about half the time conventional utensils take.

Sridhar Komarneni says that the new material he and his colleagues have designed for use in microwaves not only heats foods and beverages more quickly, but also saves energy.

He has revealed that a rice cooker and plates made from the material are already being sold by ASAHI Ceramics Research Co. in Japan.

Apes can follow conversations the same way humans do

Washington, August 29 : Experts at Great Ape Trust of Iowa have opened an important new chapter in a decades-long debate about the linguistic capabilities of apes, by applying linguistic tools used to analyse human language to a conversation between a language-competent bonobo and a scientist.

Janni Pedersen, an Iowa State University Ph. D. candidate from Denmark, and William M. Fields, director of bonobo research at Great Ape Trust, say that their study indicates the bonobos may exhibit larger linguistic competency in ordinary conversation than in controlled experimental settings.
