The researchers decided to look at T. occidentalis after previous research found the plant had lost genes that were also missing in carnivorous plants. They examined the concentration of nitrogen within the plant and found it comparable to carnivorous plants, suggesting it could be acquiring the nitrogen from insects.
Now Qianshi Lin and her colleagues at the University of British Columbia in Canada have demonstrated that a small flowering plant called Triantha occidentalis is also a meat-eater.“It is not just another species of known carnivorous plants,” says Lin. “This is a totally new group of carnivorous plants.”
A plant that grows in bogs along the west coast of North America has been spotted using its flowers to eat insects. Until now, researchers had no idea it was carnivorous.Carnivorous plants absorb nutrients from insects and sometimes vertebrates. Before now, there were 11 known groups of such plants
Those consequences include more extreme heat, heavier and more variable rainfall of the kind that caused floods recently in Germany, plus more snow loss and permafrost thaw. to be ice-free in summer further endangering polar bears and speeding up warming as less of the sun’s energy is reflected back to space.
However, the good news is the most ambitious scenario, with emissions cut to net zero and removed from the atmosphere, would see warming later fall back to 1.4°C by 2100. “The 1.5°C or 2°C goals, they are not cliff edges,” says Ed Hawkins of the University of Reading, UK, an author on the IPCC report.
In the worst of five scenarios detailing how future global emissions may play out, the world faces a catastrophic 4.4°C average temperature rise by 2100, the IPCC concluded. Under all five scenarios warming reaches or exceed the 1.5°C goal of the 2015 Paris Agreement, which also set a weaker goal of holding warming
Researchers said each of the last four decades has been successively warmer than any decade since 1850, and warned of more extreme weather if emissions are not checked. This year has already seen deadly floods and heatwaves, from Canada to China. “Climate change is not a problem of the future
Earth will unavoidably hit the critical threshold of 1.5°C warming due to climate change within the next 20 years, regardless of how radically global governments cut greenhouse gas emissions, a landmark scientific report has projected. 195 countries on 6 August and published today, the Intergovernmental Panel
Over hundreds of metres of strata, it seems that the only layers that are demonstrably lacustrine [formed in a lake] are the lower few metres,” says Michalski. “Of the rocks visited by the rover… the fraction that is demonstrably lacustrine is something like 1 per cent.”These rocks were mostly in the lowest few metres.
Instead, they analysed the concentrations of various compounds that are expected to change based on different types of weathering over time. They found that some of the layers of rock Curiosity examined did interact with water at some point in their past, but more are likely to have formed outside of the water.
Previous analyses of data from Curiosity have relied heavily on a measure called the chemical index of alteration to determine how. Joseph Michalski at the University of Hong Kong and his colleagues have suggested that because this measure was developed for use on Earth, it may not be valid in the extreme Martian climate.
A purported ancient lake on Mars may have been far smaller than researchers thought. NASA’s Curiosity rover has been exploring Gale crater for more than eight years, and while early observations suggested the entire crater may once have been filled with water, a new analysis implies that it just had a series of ponds instead.

The researchers thought that an alternative might be to freeze-dry sperm onto a surface and send it through the standard mail. materials, including filter paper and vinyl sheets, the team discovered that weighing paper – a form of paper used to hold samples being weighed in scientific analyses – was the best option.
Sperm is often transported nationally and internationally, but the glass vials typically used for transport are vulnerable to breaking in transit. University of Yamanashi in Japan has now come up with a way to deliver of sample loss. The method involves placing sperm on a sheet of paper and popping it in the post.

Over the years, Public Health England, a government agency, has set voluntary targets for reducing the calories, sugar and salt content of processed foods sold in the country. The voluntary targets were set in the hopes to change the nutritional content of their products rather than forcing reformulations.

Unlike most other arachnids, harvestmen have changed little during their evolution and their genome architecture may resemble relatively closely that of the oldest arachnids that lived more than 400 million years ago. That makes them ideal models for studying arachnid genetics, says research team member .
Harvestmen are arachnids, but they aren’t spiders: they instead belong to a closely related group called the opiliones. They have 8 extraordinarily long legs that can measure up to 28 times their body length, and they can bend the tips of them to wrap around and grasp objects.
Black holes with “hair” will quickly go bald. A key theoretical prediction about black holes called the no-hair theorem states that an isolated black hole can be described by just three numbers – its mass, spin and charge – and any other properties, or “hair”, are irrelevant.
