Man Utd boss Ole Gunnar Solskjaer fires Liverpool shots and teases full strength XI

Ole Gunnar Solskjaer has stoked tensions ahead of the visit of Liverpool insisting he does not care if he has damaged their Champions League hopes. The Manchester United manager delivered one blow to the former Champions top four hopes when fielding a second-string side in defeat against Leicester City on Tuesday.
And he said he offers no apology for restoring his big guns to the starting line-up for a fixture originally postponed because of the protests of their own fans.

Asked about any possible backlash from an angry Liverpool side, Solskjaer insisted he had no such concerns, as he seeks to deal a second blow to the Reds and all-but end their top-four prospects.

“My job is Man United and my concern is the Man United fans, what they think about my team, what they want from my team,” he said.

“It is that we come together as one and show what Man United is.”

Solskjaer made 10 changes against the Foxes including two teenagers with Anthony Elanga given a club debut and Amad Diallo a first Premier League start.

That the the star names are back for Liverpool on Thursday night is bound to raise temperatures given Leicester’s win left Jurgen Klopp’s men seven points off the top four with just four games left.

“There’ll be changes, of course, but many of the players that played against Leicester did really well, so they’re in contention as well,” said Solskjaer.

“It’s about managing the squad now, building momentum and confidence, making sure we get enough points to get second and then going into the final confident.”

Liverpool is the first of United’s three remaining games with Solskjaer’s side hosting relegated Fulham next Tuesday and finishing with a trip to Wolves on May 23.

And while Solskjaer will demand his side hold on to second place, the Europa League Final against Villareal in Gdansk three days later is already dominating thinking.

Solskjaer has ruled Harry Maguire out of their remaining Premier League fixtures after he sustained ankle ligament damage against Aston Villa last Sunday.

However the United manager remains “hopeful” the injury will not rule him out of a shot at silverware in Europe.

“The good news is it wasn’t broken, there was no fracture, but a ligament injury is serious,” said Solskjaer.

“If I said I was very positive that is maybe stretching it, but I’m hopeful he might be ready for it.

“I don’t think he’ll play inthe league again but we’ll do everything we can to get him ready for the final.”

With a further two weeks between United’s final date and the start of England’s European Championship campaign on June 13 Maguire could miss Gdansk but be fit for international duty.

“If he’s fit he’ll play for us, if he’s not he won’t,” said Solskjaer. “We’re hopeful he’s ready and if he’s ready for us he’ll be ready for the Euros.”

Predicted Man Utd XI vs Liverpool: Henderson; Wan-Bissaka, Lindelof, Bailly, Shaw; McTominay, Fred; Greenwood, Fernandes, Rashford; Cavani

Baby mantis shrimp punch their prey with superior strength

Mantis shrimp, a diverse group of predatory crustaceans with famously kooky eyeballs that move independently, can be found all over the world. But the various species all have something in common: They pack a pretty gnarly punch. In fact, mantis shrimp are known to produce some of the fastest limb movements ever recorded, at a hair-whooshing speed of around 50 miles per hour. In a new study published on April 29 in The Journal of Experimental Biology, a team of researchers examined this striking ability in tiny larval mantis shrimp, which are no larger than a grain of rice. 

“We see these mechanisms all over biology,” says lead author Jacob Harrison, a PhD student in biology at Duke University. “You see them in jumping insects, you see them in snapping shrimp, you see them in trap jaw ants, you see them in frogs.” 

With this research, says Harrison, the team was interested in figuring out when this ability first appears in mantis shrimp, and if baby mantis shrimp can strike faster than their adult counterparts. Current mathematical models suggest that smaller organisms should produce faster accelerations. The team also wanted to know how the larval shrimp’s “strike” speed compares to the speeds at which other, similarly-sized creatures can move. 

To wind up their “punch,” mantis shrimp use a mechanism known as latch-mediated spring actuation, a process in which energy stored in a spring gets released. Think about what happens in archery, says coauthor Sheila Patek, a biology professor at Duke University. “You could use your arm to throw an arrow, but it wouldn’t go very fast,” Patek says. “However, if you use your arm muscle to put energy into the deformation of the bow, you can store up a lot of energy in the material.” Released with a latch (in this case, your fingers), the energy from the bow launches the arrow. For mantis shrimp, it’s a similar process—when their “latch” muscles relax, just like when your fingers relax on a bow, it allows for stored-up energy to release and propel their forelimb forward. 

All mantis shrimp species use this system, but in different ways. Some species are known, delightfully, as “smashers”—they live underneath rocks in coral habitats, foraging for hard-shelled prey like snails and then smashing them open with a hammer-shaped appendage. Others are called “spearers,” tending to burrow into the ground and ambush fish and squid with a kind of built-in spear. Before all of this, however, they each go through various larval stages, at one point floating up to the open ocean to live briefly as see-through plankton before floating back down and into adulthood. 

Harrison, who led this study as a part of his PhD research, collected an egg clutch from a female Philippine mantis shrimp, or Gonodactylaceus falcatus, living in the wild on the island of  Oahu in Hawaii. He raised the tiny shrimp in the lab, rearing the eggs on a speed shaker table to keep the water in motion, kind of like a mantis shrimp bassinet. 

The researchers found that at the fourth larval stage—when the mantis shrimp larvae float up and become plankton—“that’s when we first started seeing this [punching] behavior,” says Harrison. It was particularly exciting for the researchers that, because the animals were completely transparent at this stage, “you can see all the muscles contracting, and you can see all the mechanisms working.” But capturing this incredibly tiny detail on camera, even using the most advanced technologies, was a challenge, he added. Eventually, they had to glue individuals to a toothpick and poke at them with another, eliciting a defensive punch.  

The study’s findings suggest that while the larval strikes were fast—at an average of about 0.9 miles per hour—they were not faster than the adults, as anticipated. “These are incredibly high speeds and accelerations for such a tiny organism, but still not quite as high as you might expect,” says Harrison. They were, however, five to ten times faster than the overall speeds of other comparably-sized species. If these baby mantis shrimp were considerably out-punching their prey, Harrison speculates, “it might be that there’s no selective pressure to get faster.” 

It’s also always possible, he says, that in a natural setting and under different circumstances—say, if the larval mantis shrimp were using aggressive strikes, as opposed to defensive ones—they might move at higher speeds. 

“This is a very cool study,” wrote Andy Suarez, a professor of integrative biology at the University of Illinois who was not involved in the research, in an email to Popular Science. “Almost everything we know about these stored energy mechanisms in animals comes from the adults of a few species. This study adds to that knowledge by examining a spring loaded system in the juveniles of mantis shrimp, which are much smaller.” Suarez also noted that the study’s findings can help engineers design things like micro-sized high-speed robots or surgical tools. 

“This is a really interesting area for understanding how materials can generate extremely fast movements,” says Patek, “and how animals circumvent physical limits.”

Andrea Bocelli on ‘gift’ of singing with kids Matteo and Virginia ‘They are my strength’

Andrea added: “Finally, I leave with a great and private gift that, until recently, I had considered unattainable…

“For the first time, three Bocellis sang on stage together with their own voices: Virginia and Matteo, alongside their dad. Family is music in itself, it is the score that restores life’s harmony.

“My family is my strength, and it was so sweet to have them beside me in the enchantment of AI-Ula, a place that speaks to the heart and bears witness to a much larger family, of which we are all part, the one – thousands of years old – that unites the world in an immense, interconnected community.”

During the concert, Andrea performed Leonard Cohen’s Hallelujah alongside 9-year-old Virginia.

‘Gold symbolizes strength of the country’: Poland plans to add more bullion to its coffers

Poland wants to buy at least 100 tons of gold in the coming years to demonstrate the country’s economic strength, said the president of the central bank, Adam Glapinski.

In an interview with Sieci magazine, he said, “At the moment, we have 229 tons of gold, of which more or less half was bought during my term in office,” adding that the new holdings would be stored in Poland.

“This matters, among other things, for how the country is perceived,” Glapinski explained. He said in January that the share of gold in the central bank, which currently comprises 9% of the nation’s reserves, would rise to 20% during his next term.

Poland has been consistently boosting its bullion reserves in recent years, buying around 126 tons of gold in 2018 and 2019. The nation also repatriated around 100 tons of gold from the Bank of England’s vaults in London, which is around half of Warsaw’s holdings in the United Kingdom. Glapinski said back then “The gold symbolizes the strength of the country.”

Over the past decade central banks around the world, and particularly in Eastern Europe, the Middle East, and Asia, have ramped up purchases of gold in a shift away from the US dollar.
