Divining Roots: revealing how plants branch out to access water
New research has discovered how plant roots sense the availability of moisture in soil and then adapt their shape to optimise acquisition of water. The discovery could enable crops to be bred which are more adaptive to changes in climate conditions, such as water scarcity, and help ensure food security in the future.

Finds chloroform emissions, on the rise in East Asia, could delay ozone recovery by up to eight years
Finds chloroform emissions, on the rise in East Asia, could delay ozone recovery by up to eight years
Earlier this year, the United Nations announced that the ozone layer, which shields the Earth from the sun's harmful ultraviolet radiation, and which was severely depleted by decades of human-derived, ozone-destroying chemicals, is on the road to recovery. The dramatic turnaround is a direct result of regulations set by the 1987 Montreal Protocol, a global treaty under which nearly every country in the world, including the United States, successfully acted to ban the production of chlorofluorocarbons (CFCs), the main agents of ozone depletion.

‘Pause’ in global warming was never real, new research proves
Claims of a 'pause' in observed global temperature warming are comprehensively disproved in a pair of new studies published today. An international team of climate researchers reviewed existing data and studies and reanalysed them. They concluded there has never been a statistically significant ‘pause' in global warming.

House size increases after hurricane strikes
House size increases after hurricane strikes
Victims of hurricane strikes in the US are becoming more vulnerable to future disasters by re-building their homes bigger than before, research has suggested. In a new study Cardiff University scientists have shown that in specific locations, houses hit by hurricanes are being replaced by new houses that in some areas are more than 50 per cent bigger.

Study solves mystery of how geckos walk on water
It's official, the humble gecko is the Maserati of reptiles. Despite being just a few centimetres long, the gecko is known for its superior acrobatic skills and ability to power through the most challenging terrain, such as, climbing the tallest trees and running across cold, slippery ice. Scientists have now cracked perhaps its most head-scratching talent of all: how it walks on water.

Clue to ecosystem recovery after pollution
Scientists have discovered a fish species which significantly evolved and expanded its ecological toolset, after an effort was made to reduce pollution in its ecosystem. The study, led by the University of Glasgow and the University of Konstanz and published in Nature Ecology and Evolution , found that the gangfisch - a European whitefish subspecies - expanded its genetic diversity after habitat loss and hybridization with other whitefish subspecies during eutrophication.

Nature's 'laboratory' offers clues on how plants thrive through genetic diversity
PA 253/18 Scientists have turned to nature's own ‘laboratory' for clues about how plants adapt in the environment to ensure their own survival. A study led by researchers at The University of Nottingham has suggested that while plants evolve to adapt to their conditions, they also maintain a small degree of diversity to stay one step ahead of changing conditions.

Bulk of social media content supports climate change research
The majority of content and commentary being shared on social media supports the scientific consensus on climate change, according to new research from the Oxford Internet Institute. The findings are welcome relief from growing concern around the polarisation of the climate change debate. Despite broad consensus among scientists that climate change is both occurring and caused by human activity, the populist campaign expressing scepticism on the validity of the scientific consensus shows no signs of movement in their beliefs.

Misunderstood flying fox could prove bat species demise, warn scientists
Misunderstood flying fox could prove bat species demise, warn scientists
A large fruit-eating bat native to Mauritius is the subject of controversy over the announcement of a major cull to protect the Indian island's fruit crops, despite a lack of evidence as to the extent of damage directly attributed to the endangered species. An international team of researchers, including the University of Bristol, that monitored the damage directly caused by the Mauritian flying fox to commercial fruit has found the bat is responsible for only some, and could be managed effectively without the need to cull.

Opinion: Methods for protecting England’s coastal communities ’not fit for purpose’
Professor Tom Spencer from Cambridge's Department of Geography and Professor Gerd Masselink from the University of Plymouth say evidence suggests there should be far stricter controls on coastal developments. In October 2018, a stark report suggested that current methods being used to protect England's coastal communities are 'not fit for purpose'.
