24 Jun 2016: Cities on Six Continents
Join Forces to Combat Climate Change

Mayors from more than 7,100 cities on six continents announced this week that they are creating a new alliance to fight climate change at the local level.

New York City
The new group — a merger of the European Union-based Covenant of Mayors and the United Nations-backed Compact of Mayors — represents a combined 600 million people in 119 countries. The initiative aims to set city-based CO2 emissions cuts, build sustainable communities, and foster the sharing of resiliency policies and technologies. “Cities are key to solving the climate change challenge,” former New York Mayor Michael Bloomberg and Maroš Šefčovič, vice-president of the European Commission, wrote in The Guardian. “They account for most of the world’s carbon emissions, and mayors often have control over the largest sources. Cities can also act quickly to confront climate change, without the political and bureaucratic hurdles that often hold back national governments.”

23 Jun 2016: Scientists Discover Contagious
Cancer in More Species of Shellfish

Last year, scientists discovered a type of contagious cancer in soft-shell clams in which free-floating cells transmitted the disease from one animal to another.

Mussels
Now, a team of Columbia University researchers is reporting that contagious cancers in the ocean may be more common than previously thought and can not only jump from animal to animal, but across species. According to the new study published in Nature, the leukemia-like cancer, known as disseminated neoplasia, has been found in three more species of bivalves: mussels, cockles, and golden carpet shell clams. The cancer cells were genetically distinct from their hosts, indicating they originated elsewhere. Transmissible cancer had previously been found in Tasmanian devils and dogs, but there’s no indication that humans are at risk. “I would only worry deeply if I was a mollusk,” Stephen P. Goff, a molecular biologist at Columbia University and co-author of the study, told The New York Times.

16 Jun 2016: Some Coral Reef “Bright Spots”
Remain, Despite Devastating Bleaching

After decades of being overfished and mismanaged, and the worst bleaching event on record this year, scientists reported in the journal Nature this week that there remain some “bright spots” among the world’s coral reefs

Coral reef on the Palmyra Atoll in the Pacific.
– systems that are doing better than anyone expected. The study examined 18 different factors at 2,514 reefs in 46 nations, including water depth, tourism, fishing, and population density. Those systems that were still thriving — defined by the scientists as having more fish than expected — tended to be managed by, and accessible only to, local fishermen and indigenous groups. This included reefs in places like the Solomon Islands, parts of Indonesia, Papua New Guinea, and Kiribati. “There’s been a narrative about local involvement, but it’s often very token,” Joshua Cinner, a research fellow at James Cook University in Australia and lead author of the study, told The Atlantic. He said there should be more opportunity for “communities to creatively confront their own challenges.”

The cost of solar energy could drop by as much as 59 percent by 2025, from 13 cents to 6 cents per kilowatt hour, according to a new report from the International Renewable Energy Agency.

Offshore wind could become 35 percent cheaper, and onshore wind 26 percent cheaper, by 2025. The cost of building renewable energy facilities is also likely to fall, by as much as 57 percent by the middle of next decade, the report found. “Historically, cost has been cited as one of the primary barriers to switching from fossil-based energy sources to renewable energy sources, but the narrative has now changed,” Adnan Z. Amin, director-general of IRENA, said in a statement. “To continue driving the energy transition, we must now shift policy focus to support areas that will result in even greater cost declines and thus maximize the tremendous economic opportunity at hand.”

09 Jun 2016: Fish Can Recognize Human
Faces, According to One New Study

Fish now join humans, monkeys, primates, and birds as one of the few animals able to distinguish faces, according to new research published in the journal Scientific Reports this week.

James St. John/Wikimedia
The skill requires a sophisticated combination of perception and memory— and generally, a neocortex. But scientists at the University of Oxford in England and the University of Queensland in Australia were able to train archerfish to recognize human faces, despite the fact that these tropical fish don’t have complex brain structures. Archerfish typically feed by spitting water at prey, like insects. So the scientists taught the fish to spray water at images of particular human faces in exchange for food. Archerfish identified the correct person 81 percent of the time.

06 Jun 2016: Fish Choose Plastic Over
Zooplankton in Polluted Waters

Fish that grow up in waters full of plastic particles develop a taste for trash, choosing to eat plastic over zooplankton, their natural food source, according to a study published in the journal Science.

Oona Lönnstedt
The research, by ecologists at Uppsala University in Swedish, found larval perch from the Baltic Sea exposed to microplastic pollution (less than 5mm in size) had stunted growth, were less active, ignored the smell of predators, and experienced increased mortality rates. Plastic pollution has become a major problem in the world’s oceans, but scientists are just beginning to understand how these fragments can affect the health of marine species. “If early life-history stages of other species are similarly affected by microplastics, and this translates to increased mortality rates, the effects on aquatic ecosystems could be profound,” said ecologist Oona Lönnstedt, lead author of the study.

01 Jun 2016: Climate Change Could Be Making
Food Crops More Toxic, UN Report Says

As extreme weather increases in frequency and intensity, food crops are producing more chemical compounds that can be toxic to humans in large doses, according to a recent report by the United Nations Environment Programme.

Sam Fentress/Wikimedia
Crops such as wheat, maize, and soybeans generate these compounds as a natural response to environmental stressors, such as drought, floods or heat waves. But when consumed by humans for extended periods of time, they can cause illnesses like neurological diseases or cancer, according to the study. One example, the Thomson Reuters Foundation reports, is nitrate. Drought slows down plants’ conversion of nitrates into amino acids and proteins, leading to a build up of the compound. When consumed in large quantities, nitrates stop red blood cells from transporting oxygen in the human body. "We are just beginning to recognize the magnitude of toxin- related issues confronting farmers in developing countries of the tropics and sub-tropics," the UNEP report noted.

31 May 2016: Bees’ Fuzzy Bodies Help Them
Detect Electrical Charges From Flowers

Back in 2013, scientists discovered that bees can detect the electrical charges that flowers emit, helping them locate nearby food sources.

Exactly how the bees were doing this, however, remained a mystery. Now, scientists have found that the hairs on bees’ fuzzy bodies move in response to the charges, which send nerve signals to bees’ brains that flowers are nearby. The finding is an important one: Scientists have long thought that only animals in marine or moist habitats could detect electric fields, since currents are carried through water. That bees can do this in dry air opens up the possibility that other insects might have the same ability. The research, conducted by scientists at the University of Bristol in the U.K., was published this week in the journal Proceedings of the National Academy of Sciences.

What if nations chose instead to burn through all of their remaining fossil fuel reserves, equal to 5 trillion tons of CO2 emissions? According to the new study published in the journal Nature Climate Change, the world would warm an average 8 degrees Celsius (14.4 degrees F), or up to 17 degrees Celsius (30 degrees F) in the Arctic. The research was conducted by a team of climate scientists at the University of Victoria and Simon Fraser University in British Columbia who wanted to understand the worst-case scenario. “Such climate changes, if realized, would have extremely profound impacts on ecosystems, human health, agriculture, economies, and other sectors,” the researchers write.

Electricity from wind, solar, and hydropower will grow 2.9 percent annually, the report concluded, and by 2040, renewables, coal, and natural gas will each generate one-third of the world’s electricity. But diesel and gasoline will still power the majority of vehicles, with electric cars making up only 1 percent of the market, the report said. The report also found that carbon emissions from energy consumption in the developing world could grow 51 percent from 2012 to 2040 as countries like India and China modernize their economies, particularly by using coal.

10 May 2016: More than 2,000 New
Plant Species Are Found Every Year

There are currently 391,000 plant species known to science—and another 2,000 are being discovered every year, according to a new report from the U.K.’s Royal Botanic Gardens, Kew.

Paulo Gonella
Last year’s new discoveries included a nearly five-foot tall carnivorous plant first identified on Facebook, a 105-ton tree in West Africa, and 90 new species of Begonia flowers. Brazil, Australia, and China were hotspots for species discovery. The State of the World’s Plants report did find, however, that one-fifth of the world’s plant species are at risk of extinction from habitat loss, disease, invasive species, and climate change. “Plants are absolutely fundamental to humankind,” Kathy Willis, director of science at Kew, told The Guardian. “Plants provide us with everything — food, fuel, medicines, timber, and they are incredibly important for our climate regulation.

05 May 2016: With Climate Change, It Is
Survival of the Oldest, Not the Fittest

When it comes to climate change, the world’s oldest species are more likely to survive than newly evolved ones, says a new study published in the journal BMC Evolutionary Biology.

Brian Gratwicke/Flickr
The logic is relatively simple: The reason they’re so old is that they’ve been tested by abrupt environmental shifts before and have come out on top. This group includes species like the cane toad and California sea lion. More specifically, the study found the planet’s oldest animals all share at least one of the following characteristics: They come in various colors, give birth to live young (as opposed to eggs), and live at low latitudes. The research could help “predict which [species] could be better able to deal with current climate change and to better predict the threat status of species on the red list of the International Union for Conservation of Nature,” said Sylvain Dubey, an ecologist at the University of Lausanne in Switzerland and co-author of the new study.

28 Apr 2016: Half of All Farmed Fish Have
Deformed Ear Bones That Cause Hearing Loss

Farmed fish have become an increasingly larger share of the world’s seafood market in recent decades—now accounting for 50 percent of global seafood consumption.

USFWS
At the same time, however, debate about the ethics, safety and health of farmed fish versus their wild counterparts has also intensified. A new study published in the journal Nature Scientific Reports finds that half of all farmed Atlantic salmon have deformed ear bones that lead to hearing loss. These salmon are 10 times more likely to have the deformity than wild fish. The findings “raise questions about the welfare of farmed animals," said Tim Dempster, a biologist at the University of Melbourne involved in the study. It may also explain why efforts to boost wild populations by releasing farmed juveniles have proven unsuccessful. Hearing loss would prevent farmed fish from detecting predators, or restrict their ability to navigate to breeding sites, the scientists said.

27 Apr 2016: Wooden Skypscrapers Grow in
Popularity in Effort to Reduce Emissions

Architects are increasingly abandoning traditional steel-and-cement skyscrapers in favor of wood-and-glue designs — a move that experts say could help drastically reduce CO2 emissions from the world’s building sector.

Acton Ostry Architects
Creating steel, iron, and non-metallic minerals — including concrete — is an energy-intensive process that accounts for more than 10 percent of global greenhouse gas emissions. In the 1990s, developers created a product known as cross-laminated timber — planks of wood glued together by a polyurethane adhesive — with the strength and durability of traditional building materials, and far fewer CO2 emissions. With concern for climate change mounting, wood-based skyscrapers have been popping up around the globe in recent years. The University of British Columbia, for example, approved an 18-story, wooden housing complex in 2015. “This revolution has happened rather quietly and happened rather slow,” Kris Spickler, a heavy timber specialist at Structurlam, told Popular Science. “But I think we’re in a year right now where we’re going to see it explode.”

18 Apr 2016: The Complicated Case of
Global Warming’s Impact on Agriculture

Scientists have long debated whether climate change could help or hurt the world’s agricultural systems. Theoretically, additional CO2 in the atmosphere should help fuel crop growth.

Ananth BS
A farmer plows his fields in southern India.
But global warming’s other impacts, such as shifting rain patterns, higher temperatures, and extreme weather, could reduce crop yields. A new study in the journal Nature Climate Change by researchers in a half-dozen countries finds the answer depends on where you live. The scientists found yields of rain-fed wheat could increase by 10 percent, while irrigated wheat, the bulk of India and China’s production, could decline by 4 percent. Maize will decrease almost everywhere, down 8.5 percent. Rice and soybean could flourish in some areas and falter in others. “Most of the discussion around climate impacts focuses only on changes in temperature and precipitation,” said Delphine Deryng, an environmental scientist at Columbia University who led the study. “To adapt adequately, we need to understand all the factors involved.”

Following years of intense exploration and research into the microbial world, scientists have reimagined the tree of life—the iconic visual representation of the living world first proposed by Charles Darwin in 1859.

The new tree of life.
The project was led by researchers at the University of California, Berkeley, who over the last decade have been gathering DNA from across the globe—from everywhere from meadow soils and river mud to deep sea vents—to reconstruct genomes and describe thousands of new microbial species. Curious how their findings fit into the tree of life, the scientists used a supercomputer to visualize how more than 3,000 new and known species related to one another. They discovered that eukaryotes, the group that includes humans, exist on a thin twig compared to the microbial branch of the tree. “The tree of life as we know it has dramatically expanded due to new genomic sampling of previously enigmatic or unknown microbial lineages,” the authors wrote.
