https://lnkd.in/enuQBeQp FUSION ENERGY BREAKTHROUGH IGNITES DREAM OF A NEW SOURCE OF CLEAN POWER 'An engineering marvel beyond belief': What we know about the nuclear fusion breakthrough.

In a historic experiment in California scientsts achieved the golden prize of ‘energy gain’ – but there is a long way to go before fusion power plants are up and running.

US officials have announced a “major scientific breakthrough” with a successful nuclear fusion experiment that could lead to a new, abundant source of clean energy.

For the first time, researchers at the Lawrence Livermore National Laboratory (LNLL) in California were able to produce more energy from a fusion reaction than was put into it.

Scientists have been pursuing this goal – known as energy gain – for decades. Kieron Monks 13 December 2022

NOTE  Scale of ever-increasing energy demand make nuclear sources necessary.

https://lnkd.in/eRD6DuMw Nuclear fusion researchers have achieved historic energy milestone. A controlled fusion reaction has generated more energy than was put into the system for the first time, bringing viable fusion power another step closer to reality.

For the first time on Earth, a controlled fusion reaction has generated more power than it requires to run, researchers have confirmed. The experiment is a major step towards commercial fusion power, but experts say there is still a vast engineering effort needed to increase efficiency and reduce cost.

Rumours of the experiment at Lawrence Livermore National Laboratory (LLNL) in California emerged on 11 December, but the news has been formally announced in a press conference today. In an experiment on 5 December, the lab’s National Ignition Facility (NIF) fusion reactor generated a power output

of 3.15 megajoules from a laser power output of 2.05 megajoules – a gain of around 150 per cent. However, this is far outweighed by the roughly 300 megajoules drawn from the electrical grid to power the lasers in the first place.

There are two main research approaches aiming to achieve viable nuclear fusion. One uses magnetic fields to contain a plasma, while the other uses lasers. NIF uses the second approach, known as inertial confinement fusion (ICF), where a tiny capsule containing hydrogen fuel is blasted with lasers, causing it to heat up and rapidly expand.

Okay, so it really bugs me that certain publications I receive are in compostable packaging. I live in a small terraced house, so have no compost bin. Also, my local authority does not collect food waste. This means that the wrapper will just end up in the grey bin for land fill. Why won’t they go back to using a paper envelope which could then be recycled??? Also, and here’s a thought, how about sending me the publication electronically and without the numerous adverting inserts which just waste paper??? It feels like greenwashing for the middle classes. 😞 #green #recycle #organic #packaging #gardenorganic #newscientist (at Lancaster, Lancashire) https://www.instagram.com/p/CgjEmq6Kpkr/?igshid=NGJjMDIxMWI=

I like being nerdy and reading academic articles, but I find it hard to find things that interest me unless I spend a bunch of time filing through Google scholar and things like that. How do I find interesting science news, academic discussions, etc. as an undergrad/beginner?

You can follow specific streams on e.g. Phys.org or Eurekalerts, but that might be a bit tedious. I would recommend letting the articles come to you: set up Google Scholar alerts for scientists who publish on topics that interest you. You can also set up a ResearchGate account to do the same. When I was *first* starting to be aware of scientific papers in high school, I was getting most of my science information from reading the Economist. It's not the best venue, but it is more approachable than, say, Nature or Science, to a young student who is curious about the general goings on in the world of academia. NewScientist or something may be better. It was just what I had access to at the time.

But also bear in mind that the world has changed dramatically in the 14 years since I started undergrad (sorry, just gonna go vomit while that number sinks in). Yes, tools for finding literature are more widely available than ever, but publication rate has skyrocketed, and average quality has generally decreased because there is so much pressure to publish fast and editorial quality is lower than ever. So I don't actually know how to go about starting anymore.

All I can say is that when I was starting out, I felt like you describe. Totally overwhelmed, and unsure where to start. What I did was pursue my passion—reptiles and amphibians of Madagascar—and keep meticulous notes of those first papers I was reading.

Nowadays, I typically go on deep dives a bit like Wikipedia rabbit holes; starting from a recent interesting article, I will flag sources they cite that I should read, and then rinse and repeat until I have 300 tabs open and cannot possibly read even the abstracts of all the work.

One important thing is to try to stay abreast of current research, while also continuing to get a better footing on the background. That will be very, very useful later in your career. Read the 'greats' on the subject of interest, but also the 'up-and-comings'/'movers and shakers'. But this is probably advice for later, when you have established the real direction you are interested in. For now, explore the waters!

Trees may have a ‘heartbeat’ that is so slow we never noticed it. What trees do in the shadows. Trees may seem sedate but it turns out they are more active than we thought. Many trees move their branches up and down during the night. The findings hint that the trees are actively pumping water upwards in stages, and that trees have a slow version of a “pulse”. “We’ve discovered that most trees have regular periodic changes in shape, synchronised across the whole plant and shorter than a day-night cycle, which imply periodic changes in water pressure,” says András Zlinszky  NewScientist   20.April 2018

earth fact time. meet the gum-leaf skeletonizer (Uraba lugens), which is a caterpillar that stacks its old moulted heads on top of its current head! it's also known as the mad hatterpillar. they use their heads as a defence mechanism, and they can stack up to six or seven heads!

These Pollinating Crustaceans Are the Bees of the Sea

Small, bug-like creatures, Isopods, can transfer pollen to red seaweed underwater

Scientists have discovered that a small, bug-like crustacean called Idotea balthica can pollinate red seaweed, a type of algae often found growing in tide pools. 

The findings, published Thursday in the journal Science, add to a small but growing body of evidence that raises questions about whether animal-mediated pollination may have first evolved underwater, instead of on land. It’s also possible that pollination evolved in separate instances, underwater and on land.

“Until recently, fertilization with the help of animals was believed to have emerged among plants when they moved ashore 450 million years ago,” says Myriam Valero, a biologist at Sorbonne University and one of the study’s authors, to NewScientist’s Carissa Wong. 

“Red algae arose over 800 million years ago and their fertilization via animal intermediaries may long predate the origin of pollination on land. However, we cannot rule out that different animal-mediated fertilization mechanisms evolved independently and repeatedly in terrestrial and marine environments...”
