Apple's new iPhone SE delivers incredible value and performance, has a surprisingly good camera, and handles videos well. Reviewers were impressed by the phone's A13 chipset. However, criticisms include insufficient battery life, absence of night mode, and lack of 5G support. "For those of us concerned about money ... the SE provides the greatest bang for the buck," said tech analyst Rob Enderle.

Cracked or broken mobile device screens can be costly to fix, but a few inexpensive DIY strategies can eliminate a repair shop visit and salvage your tablet or phone. It is relatively easy and cheap to replace the glass on a phone once you get the hang of it. Tablets are a bit more involved because of the larger size and added components. Tools might require an additional monetary outlay.

Far-right groups and individuals in the United States are exploiting the COVID-19 pandemic to promote disinformation, hate, extremism and authoritarianism. "COVID-19 has been seized by far-right groups as an opportunity to call for extreme violence," states a report from ISD, based on a combination of natural language processing, network analysis and ethnographic online research.

In what could be a trial run for more of the same, Red Hat last week held a first-ever virtual technical summit to spread the word about its latest cloud tech offerings. CEO Paul Cormier welcomed online viewers to the conference, which attracted more than 80,000 virtual attendees. The company made several key announcements during the online gathering and highlighted customer innovations.

Microsoft has introduced a slew of new products, including the Surface Go 2, the Surface Book 3, Surface Headphones 2 and Surface Earbuds. Both the Surface Go 2 and the Surface Book 3 come in consumer and corporate versions. "The two products are very different," noted Rob Enderle, principal analyst at the Enderle Group. "The Go 2 is a high-value product -- the Surface Book 3 high innovation."

People have been giving presentations for thousands of years, from Moses with his stone tablets to Elon Musk revealing his grand plans to colonize Mars. While the elements of a great pitchman generally have remained the same over the past 5,000 years -- conviction, charisma, credibility -- today's successful presenters do more than just get in front of an audience and talk.

In today's evolving business environment, every operational decision is critical -- and that includes best practices for managing the customer journey. The CRM platform is an integral part of the process. In fact, 91 percent of companies with more than 11 employees use a CRM system. Because of the time it saves and the structure CRM delivers, it can seem daunting for businesses to make a switch.

Does your customer relationship management strategy have what it takes to reach Generation Y? It's estimated that by 2021, an additional $394 billion in revenue could be gained from artificial intelligence adoption in CRM activities in the U.S. As companies grow and technology evolves at a faster-than-ever pace, collecting, storing and providing data is becoming a bigger and bigger task.

Customer attrition and churn are not new problems. Anyone who has spent time in the sales world has heard statistics around the cost of acquiring a new customer. It can be five to 25 times more expensive to acquire a new customer than to retain an existing one. Improving customer retention by just 5 percent can increase profits by 25-95 percent, depending on your industry and company size.

The U.S. Postal Service recently has been battered by a decline in the number of packages it delivers, partly caused by the coronavirus situation. It reportedly is losing $2 billion each month and will be "illiquid" by Sept. 30. The USPS is chartered to do the hard and often unprofitable work no one else wants to do, but the White House has rejected talk of a bailout for the service.

Merchants soon will be able to sell products on Google Shopping at no charge. Previously, they had to pay per click, but the cost was not fixed. There was no minimum, but they had to set a maximum for ad spend and Google would stop displaying their ads once the maximum was reached. Starting next week, search results on the Google Shopping tab will consist primarily of free product listings.

Mitochondrial fission catalyzed by dynamin-related protein 1 (Drp1) is necessary for mitochondrial biogenesis and maintenance of healthy mitochondria. However, excessive fission has been associated with multiple neurodegenerative disorders, and we recently reported that mice with smaller mitochondria are sensitized to ischemic stroke injury. Although pharmacological Drp1 inhibition has been put forward as neuroprotective, the specificity and mechanism of the inhibitor used is controversial. Here, we provide genetic evidence that Drp1 inhibition is neuroprotective. Drp1 is activated by dephosphorylation of an inhibitory phosphorylation site, Ser637. We identify Bβ2, a mitochondria-localized protein phosphatase 2A (PP2A) regulatory subunit, as a neuron-specific Drp1 activator in vivo. Bβ2 KO mice of both sexes display elongated mitochondria in neurons and are protected from cerebral ischemic injury. Functionally, deletion of Bβ2 and maintained Drp1 Ser637 phosphorylation improved mitochondrial respiratory capacity, Ca²⁺ homeostasis, and attenuated superoxide production in response to ischemia and excitotoxicity in vitro and ex vivo. Last, deletion of Bβ2 rescued excessive stroke damage associated with dephosphorylation of Drp1 S637 and mitochondrial fission. These results indicate that the state of mitochondrial connectivity and PP2A/Bβ2-mediated dephosphorylation of Drp1 play a critical role in determining the severity of cerebral ischemic injury. Therefore, Bβ2 may represent a target for prophylactic neuroprotective therapy in populations at high risk of stroke.

SIGNIFICANCE STATEMENT With recent advances in clinical practice including mechanical thrombectomy up to 24 h after the ischemic event, there is resurgent interest in neuroprotective stroke therapies. In this study, we demonstrate reduced stroke damage in the brain of mice lacking the Bβ2 regulatory subunit of protein phosphatase 2A, which we have shown previously acts as a positive regulator of the mitochondrial fission enzyme dynamin-related protein 1 (Drp1). Importantly, we provide evidence that deletion of Bβ2 can rescue excessive ischemic damage in mice lacking the mitochondrial PKA scaffold AKAP1, apparently via opposing effects on Drp1 S637 phosphorylation. These results highlight reversible phosphorylation in bidirectional regulation of Drp1 activity and identify Bβ2 as a potential pharmacological target to protect the brain from stroke injury.

Krabbe's disease is an infantile neurodegenerative disease, which is affected by mutations in the lysosomal enzyme galactocerebrosidase, leading to the accumulation of its metabolite psychosine. We have shown previously that the S1P receptor agonist fingolimod (FTY720) attenuates psychosine-induced glial cell death and demyelination both in vitro and ex vivo models. These data, together with a lack of therapies for Krabbe's disease, prompted the current preclinical study examining the effects of fingolimod in twitcher mice, a murine model of Krabbe's disease. Twitcher mice, both male and female, carrying a natural mutation in the galc gene were given fingolimod via drinking water (1 mg/kg/d). The direct impact of fingolimod administration was assessed via histochemical and biochemical analysis using markers of myelin, astrocytes, microglia, neurons, globoid cells, and immune cells. The effects of fingolimod on twitching behavior and life span were also demonstrated. Our results show that treatment of twitcher mice with fingolimod significantly rescued myelin levels compared with vehicle-treated animals and also regulated astrocyte and microglial reactivity. Furthermore, nonphosphorylated neurofilament levels were decreased, indicating neuroprotective and neurorestorative processes. These protective effects of fingolimod on twitcher mice brain pathology was reflected by an increased life span of fingolimod-treated twitcher mice. These in vivo findings corroborate initial in vitro studies and highlight the potential use of S1P receptors as drug targets for treatment of Krabbe's disease.

SIGNIFICANCE STATEMENT This study demonstrates that the administration of the therapy known as fingolimod in a mouse model of Krabbe's disease (namely, the twitcher mouse model) significantly rescues myelin levels. Further, the drug fingolimod also regulates the reactivity of glial cells, astrocytes and microglia, in this mouse model. These protective effects of fingolimod result in an increased life span of twitcher mice.
