New research shows an iceless Greenland may be in our future


media thumbnail New research shows an iceless Greenland may be in the future. If worldwide greenhouse gas emissions remain on their current trajectory, Greenland may be ice-free by the year 3000. Even by the end of the century, the island could lose 4.5% of its ice, contributing up to 13 inches of sea level rise. Číst dále >>> Přeložit do en

Melting of Himalayan glaciers has doubled in recent years


media thumbnail A newly comprehensive study shows that melting of Himalayan glaciers caused by rising temperatures has accelerated dramatically since the start of the 21st century. The analysis, spanning 40 years of satellite observations across India, China, Nepal and Bhutan, indicates that glaciers have been losing the equivalent of more than a vertical foot and half of ice each year since 2000—double the amount of melting that took place from 1975 to 2000. The study is the latest and perhaps most convincing indication that climate change is eating the Himalayas' glaciers, potentially threatening water supplies for hundreds of millions of people downstream across much of Asia.

Frog protein may mitigate dangers posed by toxic marine microbes


media thumbnail A new study from UC San Francisco suggests that a protein found in the common bullfrog may one day be used to detect and neutralize a poisonous compound produced by red tides and other harmful algal blooms. The discovery comes as these waterborne toxic events are becoming increasingly common, a consequence of climate change making the world's oceans more hospitable to the microbes responsible for these formerly infrequent flare-ups.

Ediacaran dinner party featured plenty to eat, adequate sanitation, computer model shows


media thumbnail Earth's first dinner party wasn't impressive, just a bunch of soft-bodied Ediacaran organisms sunk into sediment on the ocean floor, sharing in scraps of organic matter suspended in the water around them. Číst dále >>> Přeložit do en

Groundwater pumping has significantly reduced US stream flows


media thumbnail Groundwater pumping in the last century has contributed as much as 50 percent to stream flow declines in some U.S. rivers, according to new research led by a University of Arizona hydrologist. Číst dále >>> Přeložit do en

Human migration in Oceania recreated through paper mulberry genetics


media thumbnail The migration and interaction routes of prehistoric humans throughout the islands of Oceania can be retraced using genetic differences between paper mulberry plants, a tree native to Asia cultivated for fibers to make paper and introduced into the Pacific in prehistoric times to make barkcloth. Daniela Seelenfreund of the University of Chile and Andrea Seelenfreund of the Academia de Humanismo Cristiano University, Chile report on prehistoric human movements based on the genetic analysis of this plant in a new paper published June 19 in the open-access journal PLOS ONE.

Marriage may not aid financial savings for those who favor immediate rewards


media thumbnail A study of married couples in Vietnam suggests that, when one spouse tends to favor immediate rewards, marriage does not help them commit to saving money. Hisaki Kono of Kyoto University, Japan, and Tomomi Tanaka of the World Bank, US, present these findings in the open-access journal PLOS ONE. Číst dále >>> Přeložit do en

Early Celts in Burgundy appropriated Mediterranean products and feasting practices


media thumbnail Early Celts in eastern France imported Mediterranean pottery, as well as olive oil and wine, and may have appropriated Mediterranean feasting practices, according to a study published June 19, 2019 in PLOS ONE, by Maxime Rageot from Ludwig-Maximilians-Universität München and the University of Tübingen, and colleagues.

Investigating coral and algal 'matchmaking' at the cellular level


media thumbnail What factors govern algae's success as "tenants" of their coral hosts both under optimal conditions and when oceanic temperatures rise? A Victoria University of Wellington-led team of experts that includes Carnegie's Arthur Grossman investigates this question. Číst dále >>> Přeložit do en

Finding 'Nemo's' family tree of anemones


media thumbnail Thanks in part to the popular film Finding Nemo, clownfishes are well known to the public and well represented in scientific literature. But the same can't be said for the equally colorful sea anemones—venomous, tentacled animals—that protect clownfishes and that the fish nourish and protect in return. A new study published online this month in the journal Molecular Phylogenetics and Evolution takes a step to change that, presenting a new tree of life for clownfish-hosting sea anemones along with some surprises about their taxonomy and origins.
