The PBL Climate Pledge INDC tool tracks the emission reduction proposals and policies that countries are submitting in the run-up to the Paris Climate Summit. Updated each time new countries submit their proposals, the tool gives up-to-date information on the effects of these proposals on the projected emissions of greenhouse gases. Data via PBL.
What I didn’t know at the time was that this is what time is like for most women: fragmented, interrupted by child care and housework. Whatever leisure time they have is often devoted to what others want to do – particularly the kids – and making sure everyone else is happy doing it. Often women are so preoccupied by all the other stuff that needs doing – worrying about the carpool, whether there’s anything in the fridge to cook for dinner – that the time itself is what sociologists call “contaminated.” I came to learn that women have never had a history or culture of leisure. (Unless you were a nun, one researcher later told me.) That from the dawn of humanity, high status men, removed from the drudge work of life, have enjoyed long, uninterrupted hours of leisure. And in that time, they created art, philosophy, literature, they made scientific discoveries and sank into what psychologists call the peak human experience of flow. Women aren’t expected to flow.

Well! This is interesting.

Oh my god this is exactly what I try to explain to my husband and he never gets it.

And even if you have a good partner who is supportive, it doesn’t help as much as you might think. This sort of thing is baked into the cultural expectations of being female.

Did Mars once have life? To help answer that question, an international team of scientists created an incredibly powerful miniature chemistry laboratory, set to ride on the next Mars rover.
The instrument, called the Mars Organic Molecule Analyzer Mass Spectrometer (MOMA-MS), will form a key part of the ExoMars Rover, a joint mission between the European Space Agency (ESA) and Roscosmos. A mass spectrometer is crucial to send to Mars because it reveals the elements that can be found there. A Martian mass spectrometer takes a sample, typically of powdered rock, and distinguishes the different elements in the sample based on their mass.
After 8 years of designing, building, and testing, NASA scientists and engineers from NASA’s Goddard Space Flight Center said goodbye to their tiny chemistry lab and shipped it to Italy in a big pink box. Building a tiny instrument capable of conducting chemical analysis is difficult in any setting, but designing one that has to launch on a huge rocket, fly through the vacuum of space, and then operate on a planet with entirely different pressure and temperature systems? That’s herculean. And once on Mars, MOMA has a very important job to do. NASA Goddard Center Director Chris Scolese said, “This is the first intended life-detecting instrument that we have sent to Mars since Viking.”
The MOMA instrument will be capable of detecting a wide variety of organic molecules. Organic compounds are commonly associated with life, although they can be created by non-biological processes as well. Organic molecules contain carbon and hydrogen, and can include oxygen, nitrogen, and other elements.
To find these molecules on Mars, the MOMA team had to take instruments that would normally occupy a couple of workbenches in a chemistry lab and shrink them down to roughly the size of a toaster oven so they would be practical to install on a rover.
MOMA-MS, the mass spectrometer on the ExoMars rover, will build on the accomplishments from the Sample Analysis at Mars (SAM), an instrument suite on the Curiosity rover that includes a mass spectrometer. SAM collects and analyzes samples from just below the surface of Mars while ExoMars will be the first to explore deep beneath the surface, with a drill capable of taking samples from as deep as two meters (over six feet). This is important because Mars’s thin atmosphere and spotty magnetic field offer little protection from space radiation, which can gradually destroy organic molecules exposed on the surface. However, Martian sediment is an effective shield, and the team expects to find greater abundances of organic molecules in samples from beneath the surface.
On completion of the instrument, MOMA Project Scientist Will Brinckerhoff praised his colleagues, telling them, “You have had the right balance of skepticism, optimism, and ambition. Seeing this come together has made me want to do my best.”
In addition to the launch of the ESA and Roscosmos ExoMars Rover, in 2020, NASA plans to launch the Mars 2020 Rover, to search for signs of past microbial life. We are all looking forward to seeing what these two missions will find when they arrive on our neighboring planet.

The study authors have calculated the cost of the “lost ecosystem services value” our planet has suffered in the last decade and a half. According to their calculations, the loss due to land degradation averages US $43,400 to $72,000 per square km, some US $870 to $1,450 per person, globally each year. The percentage of the world’s land affected by land degradation has grown a lot in the last decades – it has doubled between the late 1970s and the early 2000s. And the process is far from its end.
“This study by ELD shows the immediate and global impact of land degradation and highlights that actions to tackle it pay off,” Karmenu Vella, European Commissioner for Environment, Fisheries and Maritime Affairs commented on the paper.
“Increased land degradation is also one of the factors that can lead to migration and it is being exacerbated by climate change. On our planet, the area affected by drought has doubled in 40 years. One third of Africa is threatened by desertification. As President Juncker said in his State of the Union speech last week, climate refugees will become a new challenge – if we do not act swiftly.”
Trident is a remote-controlled, camera-equipped underwater drone – and it’s the fastest machine yet from underwater robotics startup OpenROV. It can go as fast as Michael Phelps.
The underwater drone can stream live video to a monitor during explorations and the team at OpenROV is currently exploring VR so those playing with one of these drones can feel like they are right there in the depths with their vehicle.

Now a new filtering device, invented by a US teenager, could provide a cheap and easy way to purify water.
The renewable heavy metal filter, designed by 18-year-old Perry Alagappan, removes 99% of heavy metals from water that passes through it. The filter, built from graphene nanotubes, can be rinsed with a vinegar concentrate and reused. The highly concentrated waste can then be evaporated, leaving a deposit of pure metal that can be used in many different applications.
Alagappan, who was awarded the Stockholm Junior Water Prize at this year’sWorld Water Week, said the filter cost just $20 (£13) to make, up to five times less than existing reverse osmosis technology.
“I became interested in water purification when I visited my grandparents in India, and saw with my own eyes how electronic waste severely contaminated the environment,” said the recent high school graduate from Houston, Texas, on winning the prize.

The population of a microscopic marine alga in the north Atlantic Ocean apparently is booming due to climate change, but scientists — who’ve been caught off-guard by the development — aren’t sure what it means for the aquatic environment. Details
