Okay, pause your scrolling, guys, and listen up. I recently found out that the National Zoo in D.C is planning to close the Invertebrates House, where they exhibit honeybees, leaf-cutter ants, and butterflies,cuttlefish, octopi, blue crabs, anemones, orb-weaving spiders, and many other species.
Invertebrates make up make up roughly 97% of earth’s discovered species, including the disappearing honeybees, dwindling coral reefs, and fantastic tropical butterflies.
So, science side and bee enthusiasts,let’s get on signing this petition, and signal-boosting the hell out of this! Sign here.
#YesAllWomen tweets reveal persistent sexism in science By Fiona MacDonald via ScienceAlert. | Image Credit: First three images via ScienceAlert via Twitter, fourth image via Twitter.
And if you’re a woman, you’ll be nodding along to nine out of 10 of them.
The hashtag started after it was revealed that 22-year-old Elliot Rodger, lead suspect in the Isla Vista shooting, had shared extremely disturbing and misogynistic views in a video posted shortly before the attack.
Instead of flooding the internet with Rodger-specific fury, Twitter took the discussion to the next level and remind the world that sexism is still very much present across society, and #YesAllWomen experience it.
Among those tweets were many honest and confronting admissions of sexism from female scientists, students and communicators.
This isn’t the first time the issue of misogyny in science has been brought up, but it’s always sad and shocking to see certain opinions persist when females have come such a long way in the field.
As ScienceAlert is staffed almost entirely by women, we though we’d add a few of our own:
Because only 44 out of 835 Nobel Prize laureates are women.
Because senior scientists would still rather hire males, and pay them more.
Because people are still shocked when we tell them ScienceAlert is run by women.
Because that last tweet I screenshotted, via Hannah Hart, really hits home for myself and so many women I’ve talked to over the last few days [much less ever] when it comes to pointing out sexism in general, especially within the STEM world.

Inside the world of infection
Fungal pathogens manage to simultaneously pacify their plant victim’s defences whilst seizing host nutrition, creating a very difficult situation for any plant that becomes infected.
Here you can see three different stages of the fungal hyphae of Magnaporthe grisea invading and taking-over a plant cell.

Middle panel: After 72h of infection

Rice blast disease, which is caused by M.grisea, is one of the greatest pathogen threats to rice crops globally and since rice is an important food source its impact can be devastating.
Scientists from the Institute of Biological, Environmental and Rural Sciences at Aberystwth University, which is strategically funded by BBSRC, are studying the mechanisms behind fungal pathogen infection eventually hoping to reduce this major threat to modern agriculture.

For more images of plant infection to go:
This terrarium hasn’t been opened in 40 years! It is completely self-sufficient—the bacteria in the compost breaks down dead leaves to give the plants the carbon dioxide they need, and the moisture in the air condenses on the glass and returns to the soil to feed the plants’ roots.
A New Phytopia - Visualising the structures of life.
That title may have read as a rather grand statement but put simply without plants, life as we know it would not exist. From food, to fibre, to the air we breathe we are quite dependent on plants. The unique photos above are the babies of many different plants AKA seeds. This work has been created by academic/artist Rob Kesseler in partnership with the Kew Gardens Millenium Seed Bank.
Phytopia reveals a hidden world lying beyond the scope of the human eye. Working in the liminal territory between Art and Science. Rob K
There are many ways this work is special. First is the location, these seeds are live specimens forming a genetic bank of sorts within the Kew Millennium Seed Bank it’s quite a similar initiative to the Svalbard seed bank. Here these seeds remain protected, stocked in numbers to potentially restore plant populations if required.
Second is due to the way they are photographed by using a scanning electron microscope. Which basically uses a beam of electrons instead of light, giving the extremely fine details we can see above. These images then have layers of colour, specific to their mother plant, added to them. Rob describes this artistic process akin to how plants attract insects to attracting an audience.
Finally is the individual characteristics the photos highlight. Each seed has been honed through hundreds of years of evolution, adapting each one to succeed in a particular strategy of dispersal and growth. This brings home the fact that these plant babies are alive and individual as you or me.

Geometric Diatom, a microscopic alga, has a silica-coated wall comprised of two overlapping halves, like a box with a lid. Normally golden-brown, it has rainbow hues in this photograph because of the refraction of light.
