Those gazing up at the skies on Friday, weather permitting, would have seen a penumbral lunar eclipse, which happens when the moon passes through the Earth's shadow.

The phenomenon, which began at 17:00 GMT in the UK and ended at around 21:00, saw the moon move into Earth's penumbra, or outer shadow, causing it to look darker than normal.

Chlorine-washed chicken and hormone-treated beef will be kept out of the UK under any trade deal with the US, the environment secretary has promised.
Chlorine-washed chicken and hormone-treated beef are illegal under EU law for different reasons.
The EU says feeding cows with growth-enhancing chemicals could potentially result in harm to beef-eating humans – a suggestion the US fervently rejects.
There is, on the other hand, no human health threat from using a bleach solution to kill salmonella on chickens. In fact, it’s rather effective.
But the EU says using chlorine allows American farmers to be careless with the welfare of the chickens.
The US regards the rules against these products as a European ruse to protect its own producers, and has stated that the trade of both meat products will be central to any UK-US trade deal after Brexit.

 I think this is a really good idea. There should still be a certain carefulness to the process of handling and packaging chicken even though a bleach-solution can kill salmonella. Even though this may make things difficult for US as the UK's trade negotiator, the safety of the consumer is being taken into consideration and this is great to see.]]> https://www.bbc.com/news/business-51054700

The researchers found plant life in areas where vegetation was not previously known to grow.
In the Everest region, the study found a significant increase in vegetation in all height brackets.
Other researchers and scientists working on glaciers and water systems in the Himalayas have confirmed the expansion of vegetation.
A team used satellite data from 1993 to 2018 to measure the extent of plant cover between the tree-line and the snow-line.

"It (the research) matches the expectations of what would happen in a warmer and wetter climate," said Prof Walter Immerzeel, with the faculty of geosciences at Utrecht University in the Netherlands, who was not involved in the study.
"This is a very sensitive altitudinal belt where the snowline is. A withdrawal of the snowline to higher altitudes in this zone provides opportunity for vegetation to grow."
"Plants are indeed colonising the areas that once were glaciated in some of these Himalayas," said Elizabeth Byers, a vegetation ecologist who has carried out field studies in the Nepalese Himalayas for nearly 40 years.

Global warming is really changing the true nature of the earth. Formerly glaciated areas are now being colonised by plants and this is to show how much the temperature of the earth has risen.

Permafrost contains massive amounts of carbon which are likely to be released as climate change heats up the world.
When this carbon enters the atmosphere as CO2 and methane gas, it will itself contribute to warming the globe.
But scientists have now found a historical link between sea ice in the Arctic and the presence or absence of permafrost.
They say the expected disappearance of Arctic summer ice will speed up the loss of this permanently frozen ground.

Consumer pressure to end plastic packaging in shops could actually be harming the environment, a report says.
Firms are swapping to other packaging materials which are potentially even worse for the environment, the cross-party Parliamentary group warns.
Glass bottles, for instance, are much heavier than plastic so are far more polluting to transport.
Paper bags tend to have higher carbon emissions than plastic bags – and are more difficult to re-use.
The change in packaging materials has been prompted by concern from shoppers about the impact of plastic waste in the oceans.
But the report’s authors say the consequences of using new materials has not been properly assessed.

One firm is quoted as saying: “Consumers are hugely confused about what bio-based, compostable and biodegradable mean.
“We are aware that [by switching from plastic to other materials] we may, in some cases, be increasing our carbon footprint.”
Another said: "If I could have a magic wand, I’d like to see more joined up, top-down government intervention… We would like to see government be braver."

This is really where the confusion comes in. It is almost like the more efforts we make to try to stop our destruction of the world, the more walls we come in contact with. When we think of changing to other materials other than plastic in the hopes of recycling, it should be noted that many countries do not have the facilities to recycle as many materials as they produce and so the substances are still burnt and destroyed therefore not offering a solution to the problems at hand. I believe if the government would put in more effort and take more actions e.g by maybe banning some harmful products, then there may be seen improvements.]]> https://www.bbc.com/news/science-environment-51040155

UK meteorite hunt thwarted by equipment damage

UK scientists' bid to find a hidden population of iron meteorites in the Antarctic has been beaten into submission.


The University of Manchester team had developed a detection system it hoped would reveal the metal objects sitting just under the ice surface.

But after 18 days of survey work, the equipment has broken beyond repair.

It seems the components couldn't cope with the pounding they received as the detector was dragged across hard ice.

"This constant battering from the ice meant that anything which could fail did, and once repaired as best we could, a weakness in components remained for further exploitation," expedition co-lead Dr Geoff Evatt reported on Wednesday.

Metal meteorite quest set to get under way
Metal world 'may have iron volcanoes'
The scientists had been trying to test a theory that would explain why so few iron meteorites turn up in Antarctica compared with the rest of the world.

This theory holds that the metal objects warm up in the sunshine and melt themselves down into the ice and out of view.

The bespoke detector - modified from the technology used to locate land mines - was designed to sense the iron down to a depth of a few tens of centimetres.

The team went with two systems to be dragged behind snowmobiles. Both rapidly picked up damage as they bounced over the frozen undulated terrain of the Outer Recovery Ice Fields.

   Although it is dissappointing that they were unable to achieve their result, the glaciers prove to us that there will be a possible of uncovering lost pieces of history and more.]]> https://www.bbc.com/news/science-environment-51040336
