Aliens? Photoshop? NASA explains mysterious iceberg

Technology
A bizarre iceberg has been spotted by NASA scientists - in the shape of a near-perfect rectangle. The oddly satisfying phenomenon was discovered near the Larden C ice shelf in the Antarctic Peninsula. From yesterday's #IceBridge flight: A tabular iceberg can be seen on the right, floating among sea ice just off of the Larsen C ice shelf. The iceberg's sharp angles and flat surface indicate that it probably recently calved from the ice shelf. pic.twitter.com/XhgTrf642Z— NASA ICE (@NASA_ICE) October 17, 2018 A photo shows a thick block of ice up to a mile long dramatically protruding from a sea of thin frozen water, thought to have recently splintered off.Scientists took the snap from a plane used to monitor changing ...

Who was the mysterious gardener Miss Harrison?

Science
It's a tale of intrigue set at the turn of the 20th century in the seemingly genteel gardens of Victorian Britain.Keen horticulturist sit examinations in the principles of gardening - from the names and orders of common plants, to soils, good and bad.They compete across the country for a prestigious scholarship at the Royal Horticultural Society's flagship garden.The news that a "Miss Harrison" is the winner rocks the establishment.Nobody had considered that a woman might get the top mark."Clearly a very determined young woman, she's entered this exam, she's done well and she's claimed her rightful prize," says Fiona Davison, who looks after the libraries and archives of the RHS. "And, she single-handedly has sent the RHS into a ...

Scientists shocked by mysterious deaths of ancient trees

Science
A tree regarded as the icon of the African savannah is dying in mysterious circumstances.International scientists have discovered that most of the oldest and largest African baobabs have died over the past 12 years.They suspect the demise may be linked to climate change, although they have no direct evidence of this.The tree can grow to an enormous size, and may live hundreds if not thousands of years.The researchers, from universities in South Africa, Romania and the US, say the loss of the trees is "an event of an unprecedented magnitude".Revealing the findings in the journal, Nature Plants, they say the deaths were not caused by an epidemic."We suspect that the demise of monumental baobabs may be associated at least in part wi...
Mysterious rise in emissions of ozone-damaging chemical

Mysterious rise in emissions of ozone-damaging chemical

Science
Scientists have detected an unexpected rise in atmospheric levels of CFC-11, a chlorofluorocarbon (CFC) highly damaging to the ozone layer.Banned by the Montreal Protocol in 1987, CFC-11 was seen to be declining as expected but that fall has slowed down by 50% since 2012.Researchers say their evidence shows it's likely that new, illegal emissions of CFC-11 are coming from East Asia.These could hamper the recovery of the ozone hole and worsen climate change.CFC-11 is also known as trichlorofluoromethane, and is one of a number of CFCs that were initially developed as refrigerants during the 1930s. They were also used as propellants in aerosol sprays and in solvents. However, it took many decades for scientists to discover that whe...
