Soil fungi act like a support network for trees, study shows

Douglas fir trees in British Columbia grow faster when they have more connections to other trees by way of fungal networks living in the forest soil, according to a new U of A study. (Photo: Getty Images) Though past research has focused on seedlings, these findings give new insight into the value of fungal networks to older trees—which are more environmentally beneficial for functions like capturing carbon and stabilizing soil erosion.

“Large trees make up the bulk of the forest, so they drive what the forest is doing,” said researcher Joseph Birch, who led the study for his PhD thesis in the Faculty of Agricultural, Life & Environmental Sciences.

When they colonize the roots of a tree, fungal networks act as a sort of highway, allowing water, nutrients and even the compounds that send defence signals against insect attacks to flow back and forth among the trees.

The network also helps nutrients flow to resource-limited trees “like family units that support one another in times of stress,” Birch noted.

Cores taken from 350 Douglas firs in British Columbia showed that annual tree ring growth was related to the extent of fungal connections a tree had with other trees. “They had much higher growth than trees that had only a few connections.”

Daycares in Finland Built a ‘Forest Floor’, And It Changed Children’s Immune Systems

paivakodin pihat Before and after – Compared to other city kids who play in standard urban daycares with yards of pavement, tile and gravel, 3-, 4-, and 5-year-olds at these greened-up daycare centres in Finland showed increased T-cells and other important immune markers in their blood within 28 days.  “We also found that the intestinal microbiota of children who received greenery was similar to the intestinal microbiota of children visiting the forest every day,” says environmental scientist Marja Roslund from the University of Helsinki.

Open Sesame! Researchers discovered the second ‘key’ used by the SARS-CoV-2 virus to enter into human cells | University of Helsinki

NeurophilinBy specifically blocking neuropilin-1 with antibodies, the researchers were able to significantly reduce infection in laboratory cell cultures. “If you think of ACE2 as a door lock to enter the cell, then neuropilin-1 could be a factor that directs the virus to the door. ACE2 is expressed at very low levels in most cells. Thus, it is not easy for the virus to find doors to enter. Other factors such as neuropilin-1 might help the virus finding its door”, says Balistreri.

Since disorders in smelling are among the symptoms of COVID-19 and neuropilin-1 are known to be localized in the cell layer of the nasal cavity, the scientists examined tissue samples from deceased COVID-19 patients. “We wanted to find out whether cells equipped with neuropilin-1 are really infected by SARS-CoV-2, and found that this was the case, says Mika Simons, Professor of molecular neurobiology at the Technical University of Munich and co-leader of the study.

Não sorria para disfarçar — VEM comigo!

Existem pessoas que sorriem para disfarçar como elas verdadeiramente estão por dentro. A verdade é sempre melhor, tudo é tão explícito, que não precisa forçar nada. Sorrir para disfarçar as lamúrias é triste. Considere aquilo é uma emergência dentro de você. Tenha consciência de que nem sempre estamos bem. A maior dificuldade às vezes é […]

Não sorria para disfarçar — VEM comigo!

Smile, but when that joy comes from the inside out and not the other way around. When we smile with our eyes, when there is this spontaneity that comes from the inside, in that case, the smile causes envy, if that is the fact that you consider important to reach someone. If this is your intentional conduct, it is not so bad, but it is also not good. However, if you want to consider a more important factor than that, smile without spotlight. You will see that even our view of the world is better. Smile without an audience. That is really gratifying.

Saudi Arabia’s Crown Prince Mohammad bin Salman has dreams for a $700 billion megacity. This woman wants to stop him – ABC News

A woman in a tan leather jacket She says she receives almost daily death threats and intimidating messages, which she believes are from individuals aligned with the Saudi Government.

They’re in Arabic, but she shared some of them to the ABC.

“One day we will come and we will cut you up piece by piece,” reads one.

“We are going to throw acid in your face,” says another and “you are a non-Muslim and you should be killed”.

Alya recounts how some threats urge her not to trust her friends as they could instead be the enemy.

She knows they’re designed not only to scare her, but to make her paranoid.

She refuses to succumb.

“I knew when I chose this path there would be sacrifices,” she said.

After sustained intimidation for her social media posts and strong views on human rights, Alya left the embassy and cut her ties to Saudi Arabia in 2019.

She is now advocating on behalf of her traditional Saudi tribe, the Al-Huwaitat people, who have lived along the Red Sea coastline for hundreds of years.

Advertising for the city says it will have flying drone taxis, a Jurassic Park-like island, they’ll be an artificial moon, glow in the dark beaches and it will have more Michelin star restaurants per capita than in any other city in the world.

And the propaganda says it’s being built on “virgin” land.

But the Al-Huwaitat people dispute that and say they have lived in the area for centuries.

Alya says her tribespeople are being threatened, harassed and forcibly removed from their homes.

She began to speak out after the alleged murder of Abdul Rahim al-Huwati, a village leader who refused to move and spoke out against the project.

“This is my duty for the people. They’re asking for help and that is why I became involved and I’ll try to do my best to find the justice for the people of Neom,” she said.

Ethiopia accuses Trump of inciting ′war′ over Nile dam | News | DW | 24.10.2020 (loose lips/tweets could start a war)

Ethiopia demanded Saturday that the US “clarify” remarks by President Donald Trump in which he said Egypt may try to “blow up” the controversial Grand Ethiopian Renaissance Dam currently under construction in the East African country.

Ethiopian Foreign Minister Gedu Andargachew summoned US Ambassador Mike Raynor to demand an explanation, according to a statement from the ministry.

“The incitement of war between Ethiopia and Egypt from a sitting US president neither reflects the long-standing partnership and strategic alliance between Ethiopia and the United States nor is acceptable in international law governing interstate relations,” read the statement.

Trump made the comments on Friday during a ceremony marking normalizing relations between Israel and Sudan. The new dam is being built just 15 km (9 miles) east of Ethiopia’s border with Sudan.

“It’s a very dangerous situation because Egypt is not going to be able to live that way,” Trump told reporters in the White House.
