Rebirth of black hole

12 Feb 16
This will go down in the history books as the day when gravitational waves were detected. The discovery, made by scientists of the LIGO Science Collaboration, is an event that equals the discovery of the Higgs boson in 2012.

Attractive Wind Energy Pricing for Purchasers

16 Aug 17

Annual Wind Report has confirmed advancements in technology, improvements in performance and low wind prices. The annual report has been released by the US Department of Energy. This report presented that the wind energy pricing for land – based, utility – scale projects still exists attractive to utility and commercial purchasers.

The newly built wind projects in the U.S.A. offered prices averaging around 2¢/kWh. Also, it is driven lower by advancements in technology and reductions in cost. The annual report was prepared by the Lawrence Berkeley National Laboratory (Berkeley Lab). Ryan Wiser who is the senior scientists at Berkeley Lab said that the wind energy prices which is supported by federal tax incentives are at all-time low particularly in central United States. He also added that utilities and corporate buyers are selecting wind as the low-cost option.

The U.S. Department of Energy’s “Wind Technologies Market Report” presented their key findings and said that bigger turbines are enhancing wind project performance. The Lab’s contributions to this report were funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.

Why Pupfish Prefer To Breed Inside Salty Lakes

15 Aug 17

If you are one of those who think salt water can be consumed for good skin, nails, and teeth, make it clear that besides the bad taste, drinking salt water is a bad idea. However, the fact does not go the same way with the sea creatures.

According to a recent research, it’s been found that salty water is ideal for pupfish. In fact, Pupfish living in salty lakes on San Salvador Island were able to diversify into multiple species with different eating habits. The scientists have also analyzed that these pupfish have the capacity to interbreed with pupfish from other islands in the Caribbean.

The scientists have discovered something that has changed their perspective towards the breeding system of sea creatures. The scientists have stated that Pupfish are small, brightly colored fish. This specie lives in the coastal areas of salty lakes and eats algae. However, on San Salvador Island in the Bahamas, a group of pupfish has undergone adaptive radiation.

The adaptive radiation is a process where existing species rapidly evolve and differentiate into new species, to take advantage of a new environment.

Ancient Pottery Hints on Group Interactions

14 Aug 17

Insights have been captured on Iroquoian population’s power in 16th century through ancient pottery. A recent study showed that how decorations on ancient pottery can be used to find new clues for how groups interacted across large regions. The study got published in the journal Science Advances.

This innovative research was conducted by John P. Hart who is the Director of Research and Collections at the New York State Museum. Other researchers who worked on it were Jennifer Birch, Assistant Professor at the University of Georgia and Christian Gates St-Pierre who is the Assistant Professor at the University of Montreal. The research sheds new light on the significance of a little-understood Iroquoian population in upstate New York. It also focused on its impact on relations between two emerging Native American political powers in 16th century.

Iroquoins in northeastern North America are recognized for the Haudenosaunee (Iroquois) and Wendat (Huron) alliances in upstate New York and Southern Ontario. These are the very early records of both the groups.

Don’t Be Surprised! Scientists Can Amaze You beyond Your Expectations

13 Aug 17

This advanced era has provided scientists with the power to open the magical and mysterious box of surprises. This time the scientists have created a new tool that turns simple audio clips into realistic videos.

Let’s find out how they do it. The recent research is done by scientists from the University of Washington. As per the reports, the researchers have developed algorithms that solve a difficult challenge in the field of computer vision: turning audio clips into a realistic, lip-synced video of the person speaking those words.

With the help of this technique, the researchers have successfully generated a highly-realistic video of former president Barack Obama. In this video, the 44th President of the United States has demonstrated to be talking about terrorism, fatherhood, job creation and other topics. The scientists have created this video by using audio clips of those speeches and existing weekly video addresses that were originally on a different topic.

The scientists have also stated that the study is one of its kinds because before this no such results have been shown.

New Era of Animal Coloration Research

12 Aug 17

Have you ever wondered how Biology of color works in animals? Well, researchers have given this a fait bit of thought. According to the researchers the field of animal coloration has gone through massive expansion. These expansions have been possible because of the technological progression but, now the research stands on the verge of a new era.

Researchers have acknowledged that organisms other than humans perceive the world in a different way. Researchers have comprehended the systems of fundamental color production and how studies of function have evolved. The geographic scales where exact color measurements were collected are also throwing light on the dynamics of the developmental process.

Tim Caro the author, who has written the review article, stated “We can now pose questions about the evolution of camouflage based on what a prey’s main predator can see. We can start to appreciate that gene changes underlying color production have occurred in parallel in unrelated species”. He further stated that “Knowledge of production and perception and function of coloration is poised to make contributions to medicine, security, clothing and the military”.
