New flood damage framework helps planners prepare for sea-level rise

Scientists agree that sea levels will continue to rise this century, but projections beyond 2050 are much more uncertain regarding exactly how much higher ocean levels will be by 2100. While actions to protect against 2050 sea-level rise have a secure scientific basis, this range in late-century estimates makes it difficult for coastal communities to plan their long-term adaptation strategies.

Researchers find new minor planets beyond Neptune

Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series, the study also describes a new approach for finding similar types of objects and could aid future searches for the...

Genetics research sheds light on 'dark' portion of genome

Just as there is a mysterious dark matter that accounts for 85 percent of our universe, there is a "dark" portion of the human genome that has perplexed scientists for decades. A study published March 9, 2020, in Genome Research identifies new portions of the fruit fly genome that, until now, have been hidden in these dark, silent areas.

A graphene innovation that is music to your ears

Just over 15 years since a couple of researchers in the U.K. used adhesive tape to isolate single atomic layers of carbon, known as graphene, from a chunk of graphite, their Nobel Prize-winning discovery has fueled a revolution in ultrathin materials R&D.

Intensive management of crops and livestock spurred La Bastida's economic development

A team from the Research Group in Mediterranean Social Archaeology (ASOME) at the Universitat Autònoma de Barcelona (UAB) has led an international study to reconstruct the diet of the El Argar society of the southeast of the Iberian Peninsula (2220-1550 BCE) and distinguish the subsistence strategies of the populations of this archaeological complex. Published in PLOS ONE, the study was conducted...

Remote South American kelp forests surveyed for first time since 1973

In the kelp forests of Tierra del Fuego, at the southernmost tip of South America, the relative abundance of kelp, sea urchins, and sea stars has not changed significantly since 1973. Alan Friedlander of the National Geographic Society's Pristine Seas project and colleagues present these findings in the open-access journal PLOS ONE on March 11, 2020.

World's first experimental observation of a Kondo cloud

Physicists have been trying to observe the Kondo cloud quantum phenomenon for many decades. An international research team including a scientist from City University of Hong Kong (CityU) has recently developed a novel device that successfully measures the length of the Kondo cloud and even allows for controlling it. The findings can be regarded as a milestone in condensed matter physics, and may...

Very Large Telescope observes exoplanet where it rains iron

Researchers using ESO's Very Large Telescope (VLT) have observed an extreme planet where they suspect it rains iron. The ultra-hot giant exoplanet has a day side where temperatures climb above 2400 degrees Celsius, high enough to vaporise metals. Strong winds carry iron vapour to the cooler night side where it condenses into iron droplets.

Microbes far beneath the seafloor rely on recycling to survive

Scientists from Woods Hole Oceanographic Institution reveal how microorganisms could survive in rocks nestled thousands of feet beneath the ocean floor in the lower oceanic crust, in a study published on March 11 in Nature. The first analysis of messenger RNA—genetic material containing instructions for making different proteins—from this remote region of Earth, coupled with measurements of...

Engineers crack 58-year-old puzzle on way to quantum breakthrough

A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors.In a study published today in Nature, a team of engineers at UNSW Sydney has done what a celebrated scientist first suggested in 1961 was possible, but has eluded everyone...

Acacia bushlands prevent climate warming in Eastern Africa

Changes to the vegetation cover of land surfaces constitutes the biggest cause of increasing carbon dioxide emissions after the use of fossil fuels. Particularly in Africa, forests and bushland are continuously cleared for the requirements of farming and food security. The climate effects of forest loss have been extensively investigated, but now new information on the significance of bushlands in...

Power struggles hinder urban adaptation policies to climate change

Transformative actions implemented by cities to address and mitigate the impacts of climate change may be hindered by political struggles for municipal power. This is clear from a study developed by researchers from the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) and the Pompeu Fabra University (UPF), published in the journal CITIES, which...
