Environmental News For The Week Ending 16 May 2019
This is a collection of interesting news articles about the environment and related topics published last week. This is usually a Tuesday evening regular post at
GEI (but can be posted at other times).

Note: Because of the high volume of news regarding the coronavirus outbreak, that news has been published separately:
Covid seemed to drop out of the news this week; usually, I ll see virus stories on news sites most read or recent news lists; this week I had to go looking for them. Part of the reason was that the East Coast fuel pipeline shutdown dominated the headlines, but the underlying reason is that new cases in the US and globally are falling rapidly, even in India. And the news organizations are reluctant to cover a story that bleeds less this week than it did last week.

Signals Coming From Distant Parts Of The Universe Are Deeper Than Expected, Reveals Study
A recent study published in the journal Astrophysical Journal Letters reveal that the radio signals are now coming at lower frequencies.

A recent study published in the journal Astrophysical Journal Letters revealed that the radio signals are now coming at lower frequencies than they had been previously realised. A team of researchers from McGill University researchers and Canada s CHIME Fast Radio Burst has established that FRBs include radio waves at frequencies lower than ever. This latest discovery redraws the boundaries for theoretical astrophysicists who are trying to put their finger on the source of FRBs.
Mystery radio signals coming to us from space deeper than scientists thought
Researchers at McGill University have found that the fast radio bursts located just 500 million light-years away from Earth may be deeper in space, according to a new study

Since fast radio bursts (FRBs) were first discovered over a decade ago, scientists have puzzled over what could be generating these intense flashes of radio waves from outside of our galaxy. In a gradual process of elimination, the field of possible explanations has narrowed as new pieces of information are gathered about FRBs – how long they last, the frequencies of the radio waves detected, and so on.
Now, a team led by McGill University researchers and members of Canada’s CHIME Fast Radio Burst collaboration has established that FRBs include radio waves at frequencies lower than ever detected before, a discovery that redraws the boundaries for theoretical astrophysicists trying to put their finger on the source of FRBs.
