NASA’s goal is to land an astronaut on Mars by the late 2030s. But before then, it needs to build a lunar base as a midway point. And to build a lunar base, it needs a landing pad. To build download lagu a landing pad, it needs a space architect.

That’s Sam Ximenes, whose San Antonio-based venture Astroport Space Technologies recently won its second small business grant from NASA to continue its joint research with UTSA on how to design robots that can build a landing pad on the moon.

“The technology is here,” Ximenes said. “It’s not Star Trek anymore. It’s not fantasy. This is real.”

Astroport’s first contract with NASA last year helped it develop a furnace that could liquefy moon dust and form it into Lego-like bricks. This latest contract seeks a solution to a related problem: how to feed the furnace.

Astroport, founded in 2020 as a subsidiary of a larger company, is now chasing designs for robots — either autonomous or remote-controlled or somewhere in between — that could scoop the moon dust, which is finely granulated lunar soil or regolith, and get it into the furnace.

As multi-cloud adoption expands, lessons learned keep coming in. Solution providers are rising to the challenges of enterprises seeking the most review film cost-effective, reliable and secure way to embrace multi-cloud.

More and more companies are pursuing three key cloud initiatives to help maximize value while minimizing TCO:

Modernizing infrastructure
Modernizing operations
Modernizing applications
“We found that 83% of enterprises are already distributing applications across their own data centers, in one or more public clouds, and edge environments. As a result, roles within IT are also changing, with 90% of individuals in these same companies having roles that now span multiple cloud environments,” said Mark Lohmeyer, SVP and General Manager of the VMware Cloud Infrastructure Business Group, during VMware Explore 2022.

“We’re living now in a much more distributed, multi-cloud world,” Lohmeyer continued. “However, with this distributed environment comes a whole new set of challenges, because we now have these disparate cloud operating models, skillsets, tools and processes, SLAs, and security models.”

In many environments, that can lead to greater risk, longer time-to-value and higher cost.

“One question we’re often asked is, ‘What is the total cost of ownership (TCO) of VMware Cloud running as a native service in a public cloud compared to alternatives?’” Lohmeyer said.

VMware studied the question with hundreds of VMware Cloud users and discovered that TCO can be 67% lower with VMware Cloud.1 Customers need to look not only at the technology costs but all the enterprise-class support and workload migration costs. Because VMware has both private and public cloud services, it’s a lot easier and faster for customers to move their SDDC/private-cloud workloads to VMware Cloud on public clouds. This helps create a virtuous cycle in which more companies embrace multi-cloud architectures while freeing up investment for new innovation initiatives.

The higher spending, tax cuts and supportive policies announced in India’s Budget for 2023-24 are expected to support sustained demand growth and improve custom parking signs australia the longer-term prospects for corporates, said Fitch Ratings.

“We believe the tax cuts will boost consumer sentiment and maintain consumption growth, amid expectations of slower economic growth after the financial year ending 31 March 2023 (FY23),” said the rating agency after India presented on February 1 its annual Budget for the next financial year.

The announced income tax cuts will benefit the disposable incomes of consumers of all income groups, it said.

The income tax rebate limit available for salaried and individual taxpayers under the new income tax regime, introduced in 2020, has been hiked to ₹7 lakh from the present ₹5 lakh.

The decision to raise the investment ceilings in small savings schemes is aimed at benefiting senior citizens and the middle class who park funds in safe government deposit schemes offering higher returns than banks, Finance Secretary TV Somanathan has said.

The Budget 2023-24 raised the maximum deposit limit for Senior Citizen Savings Scheme from Rs 15 lakh to Rs 30 lakh. Also, the maximum deposit limit for Monthly Income Account Scheme will be enhanced from Rs 4.5 lakh to Rs 9 lakh for a single account and from Rs 9 lakh to Rs 15 lakh for a joint account.

In a post-budget interview with PTI, Somanathan said the ceilings under the Senior Citizen Savings Scheme have been unchanged for quite some time, and the decision to raise the ceiling is primarily a measure for the welfare of the middle class and senior citizens.

“There was a feeling that people in advanced age need safe investment options, and the incomes have increased in the period between the last revision and now. So, this doubling of the ceiling offers senior citizens a chance to put their money in a 100 per cent safe investment with an attractive interest rate, which is significantly higher than in banks,” Somanathan said.

The investment ceiling in post office monthly income schemes has not been revised since 1987. In the case of the Senior Citizen Savings Scheme (SCSS), the investment limit was fixed in 2004.

The words “movie day” probably evoke fond memories from our own international journal childhoods: Teachers rolling out the TV/VCR cart; the classroom lights flickering out; everyone scooting their desks to get a better view or a seat near a friend; and, if we were lucky, maybe even the smell of freshly microwaved popcorn. Today, when it comes to watching movies in school, the technology has changed (no more squinting to see a tiny TV in the corner!), but our students love movie days just the same — if not more.
Sometimes showing a movie in class is just the right call. Some movies can help illustrate big, complex ideas. Others help us explore detailed topics in ways that just aren’t possible otherwise. And the best movies help us enrich students’ learning about the much wider world outside of our classroom’s walls.

And to top it off, classroom movies are a great way to help students practice their media literacy skills. Active viewing is a skill that doesn’t always come naturally, but it’s something all students can practice and learn. And in today’s media-saturated world, kids need all the help they can get when it comes to different ways of thinking about what they’re seeing on screens of all sizes.

If you’re working with interior desain clients who want to keep things simple without being too bland, there are a few tricks you can try when it comes to selecting a color palette. Many clients are turned off by the idea of a beige look because it seems uninteresting and dull.

For starters, it might be worth explaining to them that there are a variety of shades in the beige family that are much more visually appealing than the classic color they might be envisioning.

However, in the spirit of bringing more interesting suggestions to the table, if you’d rather avoid suggesting beige altogether, there are a handful of unexpected neutrals that are equally versatile when it comes to simple design.

Purple
Purple might seem like an unexpected suggestion in terms of neutrals and simplicity, but if you select a shade that has a fair amount of gray or brown mixed into it, those will work as neutralizers, and will greatly soften the purple look.

If your clients are interested in experimenting with some purple, start by suggesting a lavender or a warm shade of mauve – these are both gentler, more natural looking hues that provide just a subtle hint of color.

Blue-Gray
Blue-grey is an incredibly common pick when it comes to neutral with a twist. This is an especially practical choice if you’re working on a master bedroom redesign. Not only does this color family bring a very soothing, relaxing energy to any space, it’s also very easy to mix and match with colorful accents.

Gray-Green
Again, if you choose any one of your client’s favorite colors but opt for a shade that has the right amount of grey or brown mixed in, you’re left with a more subtle version of that color, which can then be easily used as your neutral base.

This gray-green look has the same soothing effect we mentioned above, and is a popular pick for bathroom designs because of the earthy, spa-like effect it adds to a space.

An extract from three plant species reduced signs of motor disturbances in rodent models of Parkinson’s disease and lessened the associated molecular defects of the cellular recycling process known as autophagy, a study showed.

Further research is needed to confirm that the active component of the plant extract could serve as a potential treatment for Parkinson’s. But such a therapy might be able to restore autophagy-related deficiencies found in patients with the neurodegenerative disease, the scientists said.

The study, “Extract of Polygala tenuifolia, Angelica tenuissima, and Dimocarpus longan Reduces Behavioral Defect and Enhances Autophagy in Experimental Models of Parkinson’s Disease,” was published in the journal NeuroMolecular Medicine.

A common theme underlying various proposed causes of Parkinson’s disease is autophagy — a process to degrade, recycle, and eliminate unused proteins and other cellular components.

Some mutations linked to familial Parkinson’s are found in genes related to autophagy. These alterations cause an accumulation of toxic proteins that leads to cell damage and death.

A water-based extract called WIN-1001X, found in three plant species — Polygala tenuifolia, Angelica tenuissima, and Dimocarpus longan — has been shown to have protective properties by modulating autophagy in brain cells from mice with chemically induced Parkinson’s.

Further research identified a specific component in the extract, called onjisaponin B, that was responsible for activating autophagy processes.

Based on these findings, investigators centered at the Natural Product Research Center, Korea Institute of Science and Technology, in South Korea, examined the impact of an optimized extract of WIN-1001X in Parkinson’s-induced rodent models.

The optimized plant extract was prepared with a 20% ethanol solvent to increase fat-based components.

To induce Parkinson’s-like symptoms, the mice were injected with a compound called MPTP, which led to neurotoxicity in cells that produce dopamine. Dopamine is the chemical messenger deficient in Parkinson’s patients that is used by nerve cells to communicate and control body movements.

The researchers used a rotating rod test to measure motor coordination in the mice. The animals injected with MPTP showed significantly less time on the rod compared with control mice. Induced mice then treated with WIN-1001X showed a significant recovery compared with MPTP mice.

Johns Hopkins Medicine researchers say they have added to evidence that the compound farnesol, found naturally in herbs, and berries and other fruits, prevents and reverses brain damage linked to Parkinson’s disease in mouse studies.

The compound, used in flavorings and perfume-making, can prevent the loss of neurons that produce dopamine in the brains of mice by deactivating PARIS, a key protein involved in the disease’s progression. Loss of such neurons affects movement and cognition, leading to hallmark symptoms of Parkinson’s disease such as tremors, muscle rigidity, confusion and dementia. Farnesol’s ability to block PARIS, say the researchers, could guide development of new Parkinson’s disease interventions that specifically target this protein.

“Our experiments showed that farnesol both significantly prevented the loss of dopamine neurons and reversed behavioral deficits in mice, indicating its promise as a potential drug treatment to prevent Parkinson’s disease,” says Ted Dawson, M.D., Ph.D., director of the Johns Hopkins Institute for Cell Engineering and professor of neurology at the Johns Hopkins University School of Medicine.

Results of the new study, published July 28, in Science Translational Medicine, detail how the researchers identified farnesol’s potential by screening a large library of drugs to find those that inhibited PARIS.

In the brains of people with Parkinson’s disease, a buildup of PARIS slows down the manufacture of the protective protein PGC-1alpha. The protein shields brain cells from damaging reactive oxygen molecules that accumulate in the brain. Without PGC-1alpha, dopamine neurons die off, leading to the cognitive and physical changes associated with Parkinson’s disease.

To study whether farnesol could protect brains from the effects of PARIS accumulation, the researchers fed mice either a farnesol-supplemented diet or a regular mouse diet for one week. Then, the researchers administered pre-formed fibrils of the protein alpha-synuclein, which is associated with the effects of Parkinson’s disease in the brain.

The researchers found that the mice fed the farnesol diet performed better on a strength and coordination test designed to detect advancement of Parkinson’s disease symptoms. On average, the mice performed 100% better than mice injected with alpha-synuclein, but fed a regular diet.

When the researchers later studied brain tissue of mice in the two groups, they found that the mice fed a farnesol-supplemented diet had twice as many healthy dopamine neurons than mice not fed the farnesol-enriched diet. The farnesol-fed mice also had approximately 55% more of the protective protein PGC-1alpha in their brains than the untreated mice.

In chemical experiments, the researchers confirmed that farnesol binds to PARIS, changing the protein’s shape so that it can no longer interfere with PGC-1alpha production.
