Trillions of sailing jellyfish wash ashore after warm winters
New research uncovers patterns that explain why huge numbers of "by-the-wind sailor" jellyfish wash ashore and strand on beaches around the world, including up and down the US West Coast. While these mass stranding events are hard to miss, researchers actually know very little about how or why they happen. As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a st

At least 2.6 million Australians face poverty when COVID payments end and rental stress soars
Many Australians whose jobs were decimated by the COVID business shutdowns will soon be waking up to new income shocks and the prospect of rental stress. This is because people whose employers can't afford to keep them on will suddenly lose more than A$300 per week when the JobKeeper scheme ends on March 28. Worryingly, this income shock will happen just days before the payment to people on the Jo

Electrochemical synthesis of formate from CO2 using a Sn/reduced graphene oxide catalyst
The synthesis of formate, an energy carrier, from CO 2 using electricity derived from renewable sources is attracting much attention as a technology for recycling and reusing CO 2 . Here, we focus on reduced graphene oxide (rGO) as a dispersed Sn support that efficiently adsorbs CO 2 . Highly efficient synthesis of formate is observed at the interface between rGO and Sn in the electrochemical redu

Giant fossil's 'bird-brain'
The largest flightless bird ever to live weighed in up to 600kg and had a whopping head about half a metre long – but its brain was squeezed for space. Dromornis stirtoni, the largest of the 'mihirungs' (an Aboriginal word for 'giant bird'), stood up to 3m and had a cranium wider and higher than it was long due to a powerful big beak, leading Australian palaeontologists to look inside its brain sp

Is at home or remote working the future of industry?
Covid 19 has shaken the world, and one of the fields it's shaken most is the workforce. It forced many to work at home, but as I see in the news stories of working at home and how people actually like it, I'm forced to wonder, is at home work the furture? submitted by /u/I_bad_at_MATH_448 [link] [comments]

Is a united humanity possible?
I love thinking about the future. But cannot help thinking about how we truly unlock humanity's true potential. How can we eradicate poverty or diseases? Build mega space stations, deal with climate change, end wars, make sure that every human lives a meaningful life. What if instead of spending hundreds of billions or trillions on weapons and conflicts. We spend them on eradicating poverty addin

Plummeting Sperm Counts + Shrinking Penises: 'Forever Chemicals' Threaten Humanity
It's a slow motion disaster that may potentially wipe out humanity. The chemicals to blame for this crisis are found in everything from plastic containers and food wrapping, to waterproof clothes and fragrances in cleaning products, to soaps and shampoos, to electronics and carpeting. Some of them, called PFAS, are known as "forever chemicals", because they don't breakdown in the environment or t

India's renewable energy targets could be even higher
India's ambitious target of 450 gigawatts of renewable energy capacity by 2030 could go even further, say three economists. For comparison, the country's total energy generation capacity today is about 380 gigawatts, out of which 90 gigawatts are of renewable energy, not including large hydropower stations. How this plan shapes up will dictate how many fossil-fuel powerplants they can avoid build

Casual sex among young adults dipped before COVID. Why?
A decline in drinking has led to a decline in casual sex among both young men and women, research finds. The study also links the decline in casual sex with playing video games and living at home with parents—but only for men. The study, published in the journal Socius , finds that between 2007 and 2017, the percentage of 18-to 23-year-old men who had casual sex in the past month dropped from 38%

Similar but not identical evolutionary trajectories of birds in adaptation to high-elevation environments
Ever since the era of Darwin, adaptive evolution has been a cornerstone of evolutionary biology. One essential related question is do animals adapt similarly to a shared environments? Indeed, scientists have long ago observed that animals usually evolve similar phenotypes in similar environments, and thus formulated classic ecogeographical rules, as e.g., "Bergmann's Law," "Allen's Law," and "Glog

Unga ser fördelar med att stanna kvar i småstaden
Unga "ska" vilja flytta till en storstad; den som väljer att stanna kvar kan verka passiv och utan ambitioner. Men unga vuxna ser också fördelar med småstaden, som boendet och de sociala relationerna, visar forskning. Kraven på arbetsmarknaden har ökat och arbeten som tidigare fungerade som insteg på arbetsmarknaden har blivit färre. Denna utveckling får konsekvenser för unga i mindre orter, där
