Researchers link comet impact to rise of mammals

Researchers link comet impact to rise of mammals

A new study conducted by a team of American researchers has outlined new evidence for the theory that links a comet impact to an ancient rapid phase of global warming and rise of mammals.

Ancient comet impacts had profound effects on our planet's ecosystems. For instance, an asteroid that slammed into Yucatan Peninsula of Mexico nearly 66 million years ago wiped out the dinosaurs.

Hurricane Matthew causes minor damages to NASA’s Kennedy Space Center

Hurricane Matthew causes minor damages to NASA’s Kennedy Space Center

The recent category 4 Hurricane Matthew forced its way into Florida’s east coast, posing a real threat to military and commercial facilities at Cape Canaveral. But, the damage it caused was far less than what many had feared prior to its arrival.

The powerful hurricane on Oct. 6 brought winds of 90 miles per hour (mph), with top surface wind gusting as fast as 107 mph. It forced NASA to temporarily close its Kennedy Space Center (KSC). However, the hurricane ended up into the Atlantic, taking a course away from KSC.

Alaska lawmakers on lookout for potential presidential decrees blocking fishing and drilling in ocean waters

Alaska lawmakers on lookout for potential presidential decrees blocking fishing and drilling in ocean waters

Lawmakers in Alaska are looking forward for likely presidential decree that may impose a ban on fishing and drilling in the ocean waters statewide.

Sen. Lisa Murkowski and others have come up with legislation that as per them could halt upcoming presidents from taking benefit of a 110-year-old law — the Antiquities Act — to obtain lands and waters for fresh environmental protections. But, the likelihood of a fresh federal legislation to restrain executive powers during the term of President Barack Obama has passed.

Injecting wastewater from oil and gas activities underground caused 2012 Texas earthquake: Study

Injecting wastewater from oil and gas activities underground caused 2012 Texas earthquake: Study

An earthquake of the 4.8 magnitude that caused massive destruction in Texas in 2012 happened due to human activity. Scientists have said that injection of large volumes of wastewater from oil and gas activities underground was responsible for the earthquake that destructed buildings and severely affected residents near the town of Timpson, Texas.

Study’s lead researcher William Ellsworth from Stanford University and team have taken the help of remote sensing technique known as Interferometric Synthetic Aperture Radar (InSAR) to reach at the conclusion.

New tool predicts earthquakes induced by effects of pumping wastewater from oil and gas operations

New tool predicts earthquakes induced by effects of pumping wastewater from oil and gas operations

A team of geophysicists has developed a new tool by which they can predict earthquakes that take place due to the effects of pumping wastewater from oil and gas operations deep underground. Japanese Advanced Land Observing Satellite (ALOS)’s interferometric synthetic aperture radar (InSAR) is an important addition to predict such human-caused events.

Leonardo DiCarprio unveils Google’s new high-tech tool to curb illegal fishing

Google has joined hands with popular actor Leonardo DiCarprio’s foundation to crackdown on illegal fishing. The search engine giant and the foundation have launched a new high-tech tool to track down unregulated fishing.  The tool named as Global Fishing Watch was launched by Leonardo DiCaprio on Thursday. Main aim of the tool, a surveillance system, is to keep a constant check on global fishing practices taking from space and help bring decline in illegal fishing in the oceans.  At the event, DiCaprio enco

California’s new law to target short-lived climate pollutants to combat impacts of climate change

California’s new law to target short-lived climate pollutants to combat impacts of climate change

Californiaa is strengthening laws to prevent impacts of climate change
California is strengthening its steps to fight climate change. A new legislation has been signed Monday by Governor Jerry Brown as per which the state will regulate greenhouse-gas emissions linked to dairy and landfills.

Under the new law, a category of gases - short-lived climate pollutants showing significant impacts of climate change, has been included. The new law requires significant decline in different pollutants, including methane, HFC gases and soot.

Sea ice in Arctic reaches its second-lowest level this summer

Sea ice in Arctic reaches its second-lowest point this summer

After 2012 when the record for lowest level of sea ice floating on the Arctic Ocean was made, this summer Arctic has witnessed its second-lowest level. Experts have been calling the new pattern for ice activity in the Arctic as a new regime.

Mark Serreze, director of the National Snow and Ice Data Center in Colorado said that the new findings are strengthening the statement that the Arctic acts as the early warning system for impacts of climate change.

6000-year-old fabric found in Peru indicates dyeing of textiles with Indigo: Research

6000-year-old fabric found in Peru indicates dyeing of textiles with Indigo: Research

Discovery of the oldest indigo-dyed fabric from Peru has pushed back the earliest use of indigo by 1,500 years. Around 6,000 years back, the blue indigo dye was used by pre-Hispanic communities in Peru.

The findings published in Science Advances are based on the assessment of blue pigment a piece of cotton fabric found at an archaeological site in Huaca Prieta, Peru. With the use of highly sensitive equipment known as high-performance liquid chromatography, the researchers were able to know the source of blue pigment.
