Scientists discover unusual whale-dolphin hybrid swimming off the coast of Kauai

Scientists discover unusual whale-dolphin hybrid swimming off the coast of Kauai

But while the discovery is definitely cool, many news reports have jumped the gun a little bit by referring to the creature as a totally "new species". But a hybrid can also tell us something interesting about animal interactions. Even if hybrids can reproduce, they'd likely face other challenges in their environment, like being disadvantaged by their uniquely inherited traits or competition from other species.

Longest lunar eclipse of the century to happen Friday

Longest lunar eclipse of the century to happen Friday

The long duration of this eclipse is partly due to the fact that the moon will make a near-central passage through Earth's umbra. A period of complete eclipse , known as "totality", will last from 3:30 p.m.to 5:13 p.m. Unlike a solar eclipse , people can look at a lunar eclipse directly with their own eyes. North America missed out on Friday's lunar eclipse but can look forward to the next one on January 21, 2019, according to NASA . Consulte Mais Informação

10th endangered rhino dies in Kenya after botched transfer

10th endangered rhino dies in Kenya after botched transfer

The only surviving rhino from those translocated to Tsavo was attacked by a lion and is now nursing deadly wounds. However, it was soon revealed that the water in the park was too salty, causing the rhinos to become severely dehydrated. Between 1960 and 1995 numbers dropped by 98 per cent to fewer than 2,500. According to the non-profit group Save the Rhino, more than 7,200 African rhinos have been lost to poaching during the past decade. Consulte Mais Informação

Record heat waves and fires worsened by climate change, scientists say

The results show that climate change more than doubled the likelihood of the European heatwave, which could come to be known as regular summer temperatures. "This is something that society can and should prepare for - but equally there is no doubt that we can and should constrain the increasing likelihood of all kinds of extreme weather events by restricting greenhouse gas emissions as sharply as possible", Dr Otto said.

A Blood Moon Is Rising This Weekend - Here's How to See It

This apogee full moon, or micro-moon, is smaller and slower-moving, and, therefore, takes more time to cross the Earth's shadow than a full moon that is closer and moving more rapidly in orbit. According to astrologers, on July 27, 2018 in the sky can be seen the moon red.
