Novel technology that directly uses sun’s energy could lessen climate change

If this experimental solar-powered technology makes a successful transition from the laboratory to industrials-scale use, it can prove quite beneficial in reducing the effect of climate change.

Lava breakout from Kilauea volcano flows into Pacific Ocean

Lava breakout from Kilauea volcano flows into Pacific Ocean

Lava flow is originating from Kilauea volcano’s Pu ‘u ‘Ō ‘ō vent. The lava breakout in Hawaii has flowing to the Pacific Ocean last after slowing moving towards the coast for weeks. As per the USGS Hawaiian Volcano Observatory, the flow entered into the water at 1:12 am HST on Tuesday.

From the videos and photos shared, it has been found that the bright red lava produced massive amount of steam as it entered in the water. The breakout started to take place in late May and since then it has moving slow towards the coastline.

African tribe and wax-eating birds work together to find wild beehives for mutual benefit

People in Africa and wax-eating birds work together to find wild bees’ nests for mutual benefit

A new research paper presents a rare example of cooperation between humans and free-living animals. With the help of honeyguides, a species of bird, people in Africa are able to find beehives helping them to harvest honey.

Study researchers have found that humans use special calls to seek help from honeyguides and in return the birds recruit suitable human partners. In this amazing collaboration, both the bird and human reap benefits.

Navy should not be allowed to use LFA sonar systems: Ninth Circuit Court of Appeals

Navy should not be allowed to use LFA sonar systems: Ninth Circuit Court of Appeals

The Ninth Circuit Court of Appeals in California has said that low-frequency active (LFA) sonar systems used in world’s oceans violates the Marine Mammal Protection Act. Also, they have a negative impact on dolphins, seals, whales and walruses, as they are dependent on underwater sound for navigation.

LFA are used in areas covering 70% of the world’s oceans. The court has ruled out that it would not allow the Navy to use the LFA sonar systems to detect the presence of submarines. Experts said that the navy sonar systems could generate sound waves as high as 235 decibels.

First six months of 2016 were the hottest on record and remaining year could also set a new record

First six months of 2016 were the hottest on record and remaining year could also set a new record

The first six months of 2016 were the hottest on record on earth, unveils data from NASA and the National Oceanic and Atmospheric Administration. The world was 1.62 degrees Fahrenheit hotter than the average temperature in June in the 20th century.

Scientists said that all the months in the first half of this year were warmer than recorded in the past. Gavin Schmidt, climate scientist and director of NASA's Goddard Institute for Space Studies, said that on an average the first six months of 2016 were around two degrees warmer than what people have experienced in the 20th century.

Human activities have severely impacted global biodiversity: Study

Human activities have severely impacted global biodiversity: Study

A new study carried out to know the level of biodiversity on earth has found that around 58% of land on the planet has dropped below the biodiversity limits. The drop is mainly due to human land use practices and population growth which needs additional land.

Biodiversity as per study’s lead researcher Tim Newbold from the Centre for Biodiversity and Environment Research at University College London does not only impacts ecology, but also leads to changes in food production and personal well being.

Closed-mouth vocalization might be present in some dinosaurs

Closed-mouth vocalization might be present in some dinosaurs

A research paper posted online in the journal Evolution has unveiled that not every dinosaur roared ferociously. As per researchers, there were some dinosaurs that used to mumble or cooed with closed mouths.

In the study, the researchers have closely studied a way using which birds emit sounds known as closed-mouth vocalization. In order to understand when and as to how closed-mouth vocalization evolved, international researchers used a statistical approach.

Research team offers explanation for expansion of sea ice in sea ice in Antarctic region

Research team offers explanation for expansion of sea ice in sea ice in Antarctic region

A new study has shed light on as to why the sea ice in Antarctica is expanding, getting thick and spreading every year in a continuously warming world. Climate scientists from Australia and the United States said that the expansion in recent years has been majorly driven by natural climate fluctuations, particularly in sea surface temperatures.

Alaska’s Pavlof Volcano may erupt by this year’s end

Alaska’s Pavlof Volcano may erupt by this year’s end

There is a possibility that the Mount Pavlof in Alaska could erupt for the third time this year by the end of 2016. Alaska Volcano Observatory (AVO) has based its predictions on the basis of increasing seismic activity and steam emissions from the volcano.

Owing to the release of a steady plume of steam from the mountain, state authorities have raised the alert level for the area from normal to advisory status, also known as yellow alert. The officials said that the level of seismic activity at Pavlof Volcano is elevated but is lower than recorded last day.

Antarctic ozone hole in quick healing mode: Research

Antarctica ozone hole in quick healing mode: Research

A team of researchers in its paper published in the journal Science has unveiled that the Antarctic ozone hole has started to heal. It is indeed good news as around a 30 year old environmental problem is getting solved.

Study’s lead researcher Susan Solomon, MIT atmospheric scientist, said that firstly, the problem was quite worse and then it started to become stabilized and finally, the ‘ozone hole’ is healing. Solomon mentioned that the earth’s ozone layer is recovering owing to the choices and polices being made by us.
