Pixel 4a? That’s a damn good question and there a number of interesting answers, some tongue-in-cheek. For example, could Google be waiting for the public to forget that the
Apple iPhone SE (2020) is a thing before releasing the Pixel 4a? Will Google decide to introduce the Pixel 4a and Pixel 5 together? We know that the phone exists because
the Pixel 4a has been spotted at the FCC. Once again, the latest Pixel will use an e-label and there are three model numbers: G025J, G025M, and G025N. The first model number is presumed to be for U.S. variants of the phone while the other two designate models offered in other countries. Google filed the paperwork with the FCC on April 2nd.
The Google Pixel 4a is the runner up to last year’s red hot
Pixel 3a XL. For $399, consumers were buying the amazing Google photo processing prowess that gets more done with a single camera than many manufacturers can with a multiple rear-camera setup.
The FCC shares the frequency range for the Pixel 4a
The Pixel 4a (sorry boys and girls, Google doesn’t play the budget ‘XL’ game any more) is expected to hit the market wearing a 5.81-inch OLED panel with a resolution of 1080 x 2340. That works out to an aspect ratio of 19.5:9. The phone should be powered by the Snapdragon 730 chipset and sport 6GB of memory, a 50% hike from last year’s model. We could see versions of the phone with 64GB and 128GB of storage.Here’s a stunner. The expected battery capacity of 3080mAh is larger than the 2800mAh battery on the full-size
Pixel 4! The Pixel 4a is rumored to feature the same 12.2MP primary and 16MP telephoto cameras seen on the back of the Pixel 4.
Now that we know that the FCC has given a thumbs up for the Pixel 4a, the unveiling shouldn’t be that far away. Earlier this week, we told you that listings for the phone published by a couple of etailers in Europe
hinted at an early July release for the handset. We should point out that the FCC did not mention the Soli radar chip like it did when the Pixel 4 series passed through its doors. The FCC regulates the mmWave frequencies that Soli runs on. However, this really is not a major surprise since we didn’t see any hint that the feature would be available for the Pixel 4a.
“The soul we’d been excited to welcome into the world had lessons for our family that did not include joining us in a living physical body,” James Van Der Beek said

“After suffering a brutal, very public miscarriage last November, we were overjoyed to learn we were pregnant. This time, we kept the news to ourselves. But last weekend, once again, 17 weeks in… the soul we’d been excited to welcome into the world had lessons for our family that did not include joining us in a living physical body,” he wrote on Instagram.
In November 2019, he revealed the news of their miscarriage during his season of Dancing with the Stars and dedicated his dance to his wife. “My wife Kimberly and I went through every expecting parent’s worst nightmare. We lost the baby. The little soul that we had expected to welcome into our family took a shortcut to whatever lies beyond,” he said.
The couple share children Olivia, 9, Joshua, 8, Annabel, 6, Emilia, 4, and Gwendolyn, who turned 2 earlier this month. This is Kimberly’s fifth miscarriage in 9 years.

Speaking of the heartbreaking experience, Van Der Beek said on Saturday that he felt “helpless.”
“We rushed @vanderkimberly to the hospital by ambulance for another harrowing night of blood transfusions,” he continued. “And as I stood by, grateful for the good people who navigated the maze of regulations to save her life – but helpless to do much for the woman I loved other than massage her feet and try to keep her warm (with my #DWTS robe, ironically) – something kept running through my head, again and again, which I now feel compelled to share: We’ve got to take better care of each other.”
Van Der Beek added, “The world is in pain right now. There’s denial, shock, numbness, anger – all the old patterns we cling to when deep trauma is unearthed. And there are no words to ease that pain… to make the process hurt less or to solve it quickly. But the way out of it? Starts with an open, broken-hearted contemplation of this question: How can we take better care of each other?”
As his message came to an end, the star simply wrote, “To all the families who have gone through this… you are not alone.”

The couple has been candid about the miscarriages they endured on their road to expanding their family, as well as their respective recovery processes.
Last Thanksgiving, Van Der Beek expressed his appreciation for his wife. “In a place of newfound gratitude to have @vanderkimberly in this world today. Got really scary for a minute there — scary enough to wake me up to how much appreciation I have for so many things I just take for granted,” he wrote on Instagram, referring to his wife’s miscarriage, during which she said she “nearly lost my life.”
“I’d never been so open (especially with tragedy) as I’ve been these last few weeks, and you responded with love and support and prayers and shared your own stories, and we felt the energy … and it helped. So thank you,” he added.
And in early December, the actor opened up about the healing process in an Instagram post. “Still in repair,” he wrote alongside a photograph of him and his wife together at the beach.
“Discovering that healing happens at its own pace. Not the pace you’d like, and definitely not the pace at which the world keeps on moving… But it happens. And there’s beauty in allowing yourself to be exactly where you’re at,” he said.
If you want to see one of the wonders of the natural world, just startle a bombardier beetle. But be careful: when the beetles are scared, they flood an internal chamber with a complex cocktail of aromatic chemicals, triggering a cascade of chemical reaction that detonates the fluid and sends it shooting out of the insect’s spray nozzle in a machine-gun-like pulse of toxic, scalding-hot vapor. The explosive, high-pressure burst of noxious chemicals doesn’t harm the beetle, but it stains and irritates human skin—and can kill smaller enemies outright.
The beetle’s extraordinary arsenal has been held up by some as a proof of God’s existence: how on earth, creationists argue, could such a complex, multistep defense mechanism evolve by chance? Now researchers at Stevens Institute of Technology in Hoboken, N.J. show how the bombardier beetle concocts its deadly explosives and in the process, learn how evolution gave rise to the beetle’s remarkable firepower.
“We explain for the first time how these incredible beetles biosynthesize chemicals to create fuel for their explosions,” said Athula Attygalle, a research professor of chemistry and lead author of the work, which appears today in the July 2020 issue of the Science of Nature. “It’s a fascinating story that nobody has been able to tell before.”
To trace the workings of the beetle’s internal chemistry set, Attygalle and colleagues at University of California, Berkeley used deuterium, a rare hydrogen isotope, to tag specially synthesized chemical blends. The team led by Kipling Will then either injected the deuterium-labeled chemicals into the beetles’ internal fluids, or mixed them with dog food and fed them to the beetles over a period of several days.
Attygalle’s team sedated the bugs by popping them in the freezer, then gently tugged at their legs, annoying the sleepy insects until they launched their defensive sprays onto carefully placed filter papers. The team also dissected some beetles, using human hairs to tie closed the tiny ducts linking their chemical reservoirs and reaction chambers, and sampling the raw chemicals used to generate explosions.
Using mass spectrometers, Attygalle checked the samples sent to Stevens for deuterium-labeled products, enabling him to figure out exactly which chemicals the beetles had incorporated into their bomb-making kits. “People have been speculating about this for at least 50 years, but at last we have a clear answer,” Attygalle said. “It turns out that the beetles’ biochemistry is even more intricate than we’d thought.”
Previously, researchers had assumed that two toxic, benzene-like chemicals called benzoquinones found in the beetles’ spray were metabolized from hydroquinone, a toxic chemical that in humans can cause cancer or genetic damage. The team at Stevens showed that in fact just one of the beetle’s benzoquinones derived from hydroquinone, with the other springing from a completely separate precursor: m-cresol, a toxin found in coal tar.
It’s fascinating that the beetles can safely metabolize such toxic chemicals, Attygalle said. In future studies, he hopes to follow the beetles’ chemical supply chain further upstream, to learn how the precursors are biosynthesized from naturally available substances.
The team’s findings also show that the beetles’ explosives rely on chemical pathways found in many other creepy-crawlies. Other animals such as millipedes also use benzoquinones to discourage predators, although they lack the bombardier’s ability to detonate their chemical defenses. Evolutionarily distant creatures such as spiders and millipedes use similar strategies, too, suggesting that multiple organisms have independently evolved ways to biosynthesize the chemicals.
That’s a reminder that the bombardier beetle, though remarkable, is part of a rich and completely natural evolutionary tapestry, Attygalle said. “By studying the similarities and differences between beetles‘ chemistry, we can see more clearly how they and other species fit together into the evolutionary tree,” he explained. “Beetles are incredibly diverse, and they all have amazing chemical stories to tell.”

Apple may finally be getting round to updating the 13-inch MacBook Pro with Intel’s tenth generation processors. The good news is that the MacOS powered laptop going to get a bucketload of extra power.

Intel’s i7-1068NG7 CPU is probably the biggest indication of the power that will be on tap. Not only is it one of Intel’s tenth generation chips (offering far more performance than the current 8th-generation chipset in the 13-inch model from 2019), it’s also a brand new chip that has yet to be confirmed by Intel. Welcome to a MacBook Pro with a cutting edge processor of the current generation.
This laptop is loaded to bear in terms of memory and storage as well. The current 13-inch MacBook Pro can be upgraded to 16 GB of RAM and 2 TB of storage, so we’re looking at a doubling of the core specs. That suggests this MacBook is going to be able to handle a lot of high end media work,especially 4K video.
On top of the hardware specs here, the new MacBook Pro is expect to follow the MacBook Air and 16-inch MacBook Pro with a new design to increase the thermal efficiency and the replacement of the butterfly keyboard with the scissor-switch based Magic Keyboard. Given the 16-inch MacBook Pro was the replacement for the 15-inch MacBook Pro, many of the geekerati are hoping for the upcoming ‘smaller’ MacBook Pro to shrink the bezels and add a millimeter or two so a 14-inch screen can be used, instead of the current 13-inch screen.

I’m pretty sure we’re looking at the top-specced MacBook Pro here, and a price that will be in excess of $3000 when it goes on sale. No doubt the entry level machine will sport a lower configuration. My best guess would be a Core i5 chip, 8 GB of memory and a 256 GB SSD, priced at around $1499.
As for the all important release date, before the coronavirus pandemic hit, the obvious time would be to do it during the keynote of the annual Worldwide Developer Conference which traditionally takes place in June. Given WWDC is going virtual, you have to assume that this new MacBook Pro will follow the same route as March’s MacBook Air with online announcements and press releases driving the awareness.
