Who gets to influence the climate negotiations?

The influence of fossil fuel corporations was strongly questioned by developing countries in the post-Paris meeting of the climate change negotiations in Bonn last week. Climate Trackers Pavlos Georgiadis, Renee Karunungan and Anna Pérez Català highlight the key issues that were debated. 

A number of developing countries, led by Ecuador, Guatemala and Bolivia are now calling for concrete measures to define how the public policy making process interacts with the private sector in climate change negotiations. What they want is special attention to be given to concerns over potential conflicts of interest between the industry and the implementation of the Paris Agreement.

Honeybees pick up 'astonishing' number of pesticides via non-crop plants

A Purdue University study shows that honeybees collect the vast majority of their pollen from plants other than crops, even in areas dominated by corn and soybeans, and that pollen is consistently contaminated with a host of agricultural and urban pesticides throughout the growing season.

Better combustion for power generation

In the United States, the use of natural gas for electricity generation continues to grow. The driving forces behind this development? A boom in domestic natural gas production, historically low prices, and increased scrutiny over fossil fuels' carbon emissions. 

What Are Nile Crocodiles Doing in Florida?

At up to 20 feet long and weighing a ton and a half, with the strongest bite in the animal kingdom, Nile crocodiles can pretty much devour anything they want to — including humans.

As you can guess from their name, these carnivorous crocs are native to sub-Saharan Africa, where they subsist on small hippos, zebras and other animals they catch and, in some cases, swallow whole.

Bright Lighting Encourages Healthy Food Choices

Dining in dimly lit restaurants has been linked to eating slowly and ultimately eating less than in brighter restaurants, but does lighting also impact how healthfully we order?

New research findings forthcoming in the Journal of Marketing Research illustrate that those dining in well-lit rooms are about 16-24% more likely to order healthy foods than those in dimly lit rooms. Furthermore, the researchers found evidence that this effect is due mainly to the level of diners’ alertness. “We feel more alert in brighter rooms and therefore tend to make more healthful, forward-thinking decisions,” explains lead author Dipayan Biswas, PhD, University of South Florida.

Living near a landfill could damage your health

According to research published today in the International Journal of Epidemiology, health is at risk for those who live within five kilometres of a landfill site. 

Spring comes sooner to urban heat islands, with potential consequences for wildlife

With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.

A Different Look at Energy Harvesting Roadways

Over fifty percent of the United States energy comes from coal and petroleum based fuels. Powering a nation in which the average person uses the amount of energy in 15,370 lbs of coal or 165,033 sticks of dynamite in a year is not sustainable. When thinking of a solution, the well-known renewable energy source that most likely comes to mind is solar power.

Solar panels are an impervious surface. Impervious surfaces already take up 32,868.61 square miles of roads, parking lots, driveways, and more. These surfaces displace rainwater to surrounding areas and have great impacts on the water table and soil quality. Utilizing already cleared land rather than clearing more would be beneficial to the environment, as solar fields require large amounts of cleared land.

Squid populations on the rise

Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world's oceans over the past 60 years, a University of Adelaide study has found.

The international team, led by researchers from the University's Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term trends in abundance, published in Cell Press journal Current Biology.

Bristol University study shows how immune cells become activated

Immune cells play essential roles in the maintenance and repair of our bodies.  When we injure ourselves, immune cells mount a rapid inflammatory response to protect us against infection and help heal the damaged tissue. 

Lead researcher Dr Helen Weavers, from the Faculty of Biomedical Sciences said: “While this immune response is beneficial for human health, many human diseases (including atheroscelerosis, cancer and arthritis) are caused or aggravated by an overzealous immune response. A greater understanding of what activates the immune response is therefore crucial for the design of novel therapies to treat these inflammatory disorders.

“Our study found that immune cells must first become ‘activated’ by eating a dying neighbouring cell before they are able to respond to wounds or infection. In this way, immune cells build a molecular memory of this meal, which shapes their inflammatory behaviour.”
