Flawed Tests on Earth May Explain Why NASA's Rovers Get Stuck on Mars
In a paper published in the Journal of Field Robotics, the team of engineers used computer simulations to uncover a missing element in the way NASA tests its rovers on Earth. Rather than only accounting for the effect of gravity on the rover prototypes being tested on Earth, the engineers behind the recent study suggest that NASA has overlooked gravity's pull on the sand itself.
The gravity on Mars is significantly weaker than on Earth. To account for the difference in gravity between Mars and Earth, NASA engineers test a lightweight prototype of the Martian rovers that are about a sixth of the mass of the robots sent to the Red Planet. The recent simulations, however, revealed that Earth's gravity pulls down on sand much more strongly than on Mars or the Moon. As a result, the sand on Earth is much more rigid and less likely to shift under the wheels of the rover, while it tends to be fluffier on the Moon.
'We need to consider not only the gravitational pull on the rover but also the effect of gravity on the sand to get a better picture of how the rover will perform on the Moon,' Dan Negrut, a professor of mechanical engineering at UW–Madison and lead author of the paper, said in a statement.
The team behind the study stumbled upon the missing piece of the puzzle while simulating NASA's VIPER, or Volatiles Investigating Polar Exploration Rover, which was meant to launch to the Moon this year before its mission got canceled. While simulating VIPER's mission, the engineers noticed discrepancies between Earth-based tests of the rover prototype and physics-based simulations of the four-wheeled robot on the Moon.
The new findings suggest that rovers on extraterrestrial terrains, like the Moon or Mars, are more likely to struggle with getting their wheels stuck in the less-cooperative sands. Something like this may have happened not just to Spirit but also to NASA's Opportunity rover, which spent weeks stuck in sand in 2005, and Curiosity, which got bogged down in soft terrain in 2014. By considering how sand behaves under the lighter gravitational pull of other worlds, NASA can better prepare its robots for the harsh terrain ahead.

Glucorem Shares Report on Blood Sugar Stabilization and Metabolic Glucose Transport Pathways (2025)
Formulated with AMPK-activating botanicals and GLUT-4 support compounds, Glucorem explores how non-stimulant glucose transport strategies are gaining momentum among wellness-focused consumers in 2025. New York, Aug. 02, 2025 (GLOBE NEWSWIRE) -- These statements have not been evaluated by the Food and Drug Administration. This article is for informational purposes only and is not intended to diagnose, treat, cure, or prevent any disease. Please consult a licensed healthcare provider before beginning any new supplement, dietary, or lifestyle regimen. Glucorem is positioning itself at the center of a growing conversation around non-stimulant blood sugar management, combining modern ingredient transparency with a science-inspired approach to glucose stability. As discussions around AMPK activation, mitochondrial efficiency, and GLUT-4 receptor function continue to rise across search engines and forums, Glucorem's formula aligns with emerging consumer curiosity around next-generation support you purchase through this link, the publisher may receive a commission at no additional cost to you. Consumer Trend or Problem Shift Across wellness circles and search behavior patterns in 2025, a new focus is emerging: how to maintain stable blood sugar without relying on harsh stimulant-based interventions. Online forums, Google search trends, and TikTok comment threads are filled with questions like 'Why do I crash after meals?', 'Is there a way to support my metabolism naturally?', and 'What do GLUT-4 receptors really do?' One growing area of exploration centers around GLUT-4 glucose transporters, which help shuttle glucose into cells, particularly after meals. These receptors often come under stress when insulin signaling is overwhelmed — something that can occur not just from sugar-laden diets, but also from years of metabolic wear and tear. Paired with rising searches around 'AMPK activation' and 'mitochondrial support,' it's clear that wellness consumers are looking deeper than calorie counting or glycemic indexes. The shift is away from silver-bullet solutions and toward ingredient-first exploration. Search queries like 'how to mimic fasting without fasting,' 'GLUT-4 natural support,' and 'non-clinical insulin sensitivity' reflect an evolving curiosity that transcends traditional diet supplements. In this climate, brands that emphasize transparent formulas and science-aligned mechanisms — without crossing into medical territory — are resonating with a more research-savvy public. This consumer awareness is reshaping the entire blood sugar discussion. Rather than simply focusing on A1C or glucose numbers, many individuals are exploring their energy levels, post-meal patterns, cravings, and cognitive clarity — all as potential reflections of underlying glucose Structure and Use Glucorem is structured around a liquid delivery format, combining botanical ingredients and timing protocols designed to align with emerging interest in metabolic synergy. It does not operate as a replacement for prescribed medications or clinical oversight. Instead, the formulation represents a non-stimulant, informationally driven design inspired by layered systems like the AMPK pathway and GLUT-4 receptor activity. Central to its model is the GlycoBalance Cascade™ — a term describing the timed interaction of six plant compounds, each explored independently in wellness circles for their roles in metabolic behavior. These compounds are delivered sublingually (under the tongue), a format often discussed in supplement communities as a way to bypass traditional digestion and support faster uptake. This approach reflects trends around metabolic flexibility, where the goal is not just to manage post-meal glucose spikes, but to support overall glucose transport, inflammation control, and energy conversion — all without stimulants or synthetic additives. Each ingredient in Glucorem is positioned to align with an aspect of the blood sugar story that users are now researching independently. Public interest in turmeric root, for example, often centers on its role in inflammation and insulin receptor behavior. Bitter melon draws attention for its ability to mimic insulin-like activity. Resveratrol from Japanese knotweed is frequently mentioned alongside AMPK and mitochondrial health, while compounds like cinnamon bark and coriander seed have long been associated with post-meal balance. None of these ingredients are positioned as magic bullets. Instead, the structure of Glucorem reflects a convergence of user interest in transparency, timing, plant synergy, and metabolic literacy. As formulas shift toward educational positioning, Glucorem appears to follow a path now favored by supplement-conscious Transparency As ingredient-conscious consumers drive demand for transparency in supplement formulations, the components of Glucorem are receiving attention not just for their origin, but for how they reflect broader interest in metabolic health research. Each inclusion serves a function aligned with popular wellness frameworks — from AMPK activation to GLUT-4 transporter behavior — while remaining rooted in non-clinical, plant-based tradition. Turmeric root extract is one of the most searched ingredients in the wellness space, often associated with inflammation-related pathways and insulin receptor sensitivity. In blood sugar-focused conversations, turmeric's curcuminoid compounds are being explored in relation to how cells respond to insulin signals, and how metabolic flexibility can be supported without pharmacological interference. Cinnamon bark is another standout, with widespread coverage in public articles and short-form videos focusing on how it may influence post-meal blood sugar patterns. Search behavior reveals a sustained curiosity around its impact on fasting glucose levels and its connection to GLUT-4 activity — the cellular transporters that manage sugar uptake after meals. Bitter melon, long used in Eastern herbal systems, is frequently mentioned in discussions about insulin-mimicking plant compounds. It draws interest from users looking to understand how natural substances can work with the body's signaling systems without acting as direct substitutes for medical interventions. Japanese knotweed offers a rich source of resveratrol, a polyphenol increasingly linked in public forums to mitochondrial efficiency and AMPK activation. AMPK, or AMP-activated protein kinase, has emerged in search trends as a cellular energy switch — a regulatory enzyme that signals when the body should begin pulling from internal energy stores rather than relying on circulating glucose. This is a topic that resonates especially with users interested in mimicking fasting effects without altering their diets. Licorice root and coriander seed round out Glucorem's formula. Licorice is often sought out for its potential to help balance adrenal activity and modulate stress-related inflammation, while coriander seed is being explored in wellness content for its post-meal blood sugar stability properties. What makes Glucorem distinct in this space is not simply the presence of these ingredients, but their interaction. The formula is constructed with an awareness of synergistic potential — how one compound may support or amplify the action of another, forming a blend greater than the sum of its Behind the System As public understanding of metabolic health deepens, many consumers are shifting their focus from surface-level sugar control to the biological systems that influence glucose movement and energy production. Glucorem is designed with this systems-level perspective in mind, drawing on pathways now commonly referenced in public forums: AMPK activation, GLUT-4 support, and mitochondrial energy regulation. AMPK, or AMP-activated protein kinase, is a cellular enzyme that plays a key role in energy sensing. Often described as the body's metabolic 'master switch,' AMPK becomes activated during periods of low energy availability — such as during exercise or fasting — and signals the body to start burning stored fuel. In wellness discussions, AMPK activation is frequently associated with better glucose clearance, increased fat metabolism, and improved mitochondrial performance. Rather than attempting to mimic pharmaceutical AMPK modulators, Glucorem includes compounds like resveratrol (from Japanese knotweed) and bitter melon, which are publicly discussed for their potential influence on this pathway. These ingredients are gaining attention among those who wish to explore metabolic switching through non-stimulant, food-derived compounds. Another major focus of Glucorem's formulation is GLUT-4 transporter activity. GLUT-4 is a type of glucose transporter found in muscle and fat tissues, responsible for moving glucose from the bloodstream into cells — particularly after insulin is released in response to a meal. When GLUT-4 becomes less responsive, it can lead to glucose buildup in the blood and contribute to unstable energy patterns. In user-led discussions across Reddit and scientific commentary alike, GLUT-4 sensitivity is increasingly seen as a valuable area of exploration for individuals interested in long-term glucose balance. Ingredients like cinnamon bark and turmeric root have been highlighted in wellness blogs and keyword trend reports for their associations with GLUT-4 signaling and insulin receptor activity. The liquid, sublingual format of Glucorem also speaks to a growing interest in fast-absorbing delivery systems. While not a medication or injection, the under-the-tongue delivery method allows the body to absorb plant compounds through mucosal membranes — potentially bypassing some of the delays and breakdown that occur during digestion. Glucorem's structure, therefore, aligns with non-clinical interest in optimizing glucose usage, cellular energy allocation, and transporter function — themes that are rapidly expanding in consumer wellness content across It's For / Use Cases Glucorem is generating interest among a broad cross-section of individuals seeking to better understand and navigate their energy patterns, glucose response, and overall metabolic behavior. While not intended as a medical treatment, the formulation reflects a new class of non-stimulant wellness tools gaining traction among self-educating consumers. Many users encountering blood sugar fluctuation symptoms — such as mid-day fatigue, post-meal crashes, and persistent cravings — are now exploring ingredient stacks that address multiple pathways at once. This includes those who have already tried traditional approaches like low-glycemic diets or intermittent fasting but are now looking into cellular-level mechanisms like insulin receptor sensitivity and GLUT-4 transport regulation. Glucorem's formulation appears to resonate particularly with individuals curious about how energy metabolism connects to daily function. This includes professionals who experience brain fog after meals, those trying to regulate eating patterns, or individuals who've noticed that their energy and mood seem directly tied to blood sugar variability. Another group showing consistent interest in products like Glucorem includes people focused on preventative wellness. These are consumers who may not have been diagnosed with any condition, but who actively track their biometrics, use continuous glucose monitors, or follow biohacking forums. Their goal is not to treat illness, but to optimize performance — especially in areas like mitochondrial efficiency, recovery, and hormonal resilience. In addition, the sublingual format has appeal among those who have difficulty with capsules, or who are exploring rapid-delivery supplementation as part of a broader wellness routine. For individuals comparing tincture-based systems, the concept of layered absorption — where ingredients interact quickly and efficiently — is a differentiator that aligns with current supplement trends. Whether navigating fluctuating energy, researching AMPK activation, or experimenting with plant-based glucose support, Glucorem is part of a larger movement toward ingredient intelligence and formulation literacy. Its design reflects not a niche use case, but a growing wellness perspective that places metabolic balance at the center of daily or Objection Handling Public curiosity around Glucorem has led to several recurring questions across forums and wellness-focused channels. While the product is not positioned as a medical intervention, many individuals are exploring it within the context of their broader blood sugar and energy regulation efforts. The following frequently asked topics reflect that interest. One common question is: 'Will Glucorem work for me if I've struggled with blood sugar regulation for years?' While results are never guaranteed, many users exploring non-stimulant systems have expressed interest in Glucorem because of its layered approach. Rather than targeting a single mechanism, it's designed with a philosophy that combines multiple glucose-related pathways — including GLUT-4 transporter sensitivity, AMPK activation, and cellular inflammation reduction. Another topic of concern is safety: 'Can I take Glucorem alongside existing routines or medications?' The formulation is built with non-synthetic, plant-based compounds that are generally recognized as safe in wellness circles. However, the brand does not claim compatibility with any medical protocol and recommends consulting a licensed professional before adding new supplements to an existing regimen. A frequently searched topic is timing: 'How long does it take to see results?' While individual experiences vary, many consumers exploring metabolic support formulas report that initial shifts — such as fewer crashes, more stable energy, or reduced cravings — may occur within 1–2 weeks. That said, systems related to glucose regulation often benefit from consistency over time. For some, noticeable changes align more closely with a 90–180 day usage window. A unique question tied to Glucorem's structure is: 'How does the sublingual delivery make a difference?' The under-the-tongue format bypasses the digestive system, allowing active ingredients to begin absorption through mucosal membranes. This is of particular interest to users researching supplement bioavailability or comparing traditional capsules with more immediate delivery models. These questions reflect a larger trend: users want to understand how and why formulations work — not just whether they're popular. Glucorem's public-facing transparency and emphasis on layered plant synergy have helped position it as part of that educational Manufacturing, Distribution Glucorem is manufactured in the United States in a GMP-certified facility that follows industry-standard safety and quality protocols.

Trick your brain into staying motivated with this simple psychology hack
Dreading a task at the end of a long week? There may be a way to trick your brain into seeing that chore as a reward. "Dopamine anchoring" is the latest psychology hack making the rounds on social media. This technique involves associating a desirable thing – like music or snacks – with a less pleasant task or movement, so that "over time, your brain begins to crave the task itself," according to Joshua Stein, M.D., a child and adolescent psychiatrist at PrairieCare in Minnesota. From a neuroscience perspective, this strategy works through the brain's dopamine pathway. Dopamine is a neurotransmitter in the brain that is associated with feelings of pleasure. "When we expect a reward, dopamine levels rise before we get the reward," which helps boost motivation, Stein told Fox News Digital. By repeatedly pairing something enjoyable with an activity like cleaning, writing or even exercising, it's possible to train the brain to release dopamine in advance, which associates pleasure with that behavior. "There is strong scientific support for this, from both behavioral psychology and neuroscience," said Stein, noting that pairing stimuli and rewards can influence behavior, even potentially helping with addiction. This anchoring technique can also be helpful for those who have conditions like ADHD or depression, where the dopamine system can become out of whack or dysregulated. "The more consistent the pattern, the stronger the association." Stein noted that some people may struggle with a condition called anhedonia, which means they have issues with experiencing pleasure, starting a task or keeping their attention focused. "By strategically anchoring pleasant stimuli to challenging tasks, individuals can essentially 'prime' the brain" to better tolerate, or even enjoy, those activities, according to the doctor. "Overall, it's about working with your brain chemistry, not against it." One of the biggest myths surrounding dopamine is that it's just a "pleasure chemical," according to Stein. "It would be more accurate to say that dopamine is the motivation or anticipation neurotransmitter," he said. While dopamine anchoring can be a helpful tool in some cases, experts say it should not be relied upon as the sole treatment. There can be downsides to relying on this technique as a self-help strategy. "Like any other psychological tool, dopamine anchoring needs to be used mindfully," Stein cautioned. There is the risk that someone could come to rely on external rewards to do anything at all, which could undermine natural motivation over time. "Like any other psychological tool, dopamine anchoring needs to be used mindfully." People should also avoid using unhealthy or overly stimulating rewards as anchors, like eating sugary snacks after reaching a goal or using social media after finishing an assignment — behaviors that can lead to dysregulation, poor focus or burnout, the expert said. Stein suggests anchoring with things that are energizing but not addictive, and building in breaks where motivation can arise more naturally. "Think of dopamine anchoring as a bridge, not a crutch," he advised. Stein also pointed out the misconception that people can endlessly boost dopamine. While short-term boosts are possible, too much artificial stimulation can dull the natural response over time. "The best way to begin practicing dopamine anchoring is to start small," Stein said. The expert offered the examples below for those looking to try this technique. "If you do this consistently, over time your brain will begin to associate that task with a sense of ease, and maybe even enjoyment," Stein said. The goal is to keep the rewards simple and non-addictive so they don't get in the way of the task, according to the expert.

And like any other form of training, the more consistent the pattern, the stronger the association."

15 Minutes of This Exercise May Lower Mortality Risk by 19%, New Study Says
Upgrade your daily walk with this small tweak that could offer lots of health benefits. Reviewed by Dietitian Mandy Enright, M.S., RDN, RYTKey Points A new study found that 15 minutes of fast walking each day may lower mortality risk by 19%. Fast walking lowered overall mortality risk and had an especially large impact on heart health-related deaths. While slower walking can be a great form of exercise, smaller quantities of fast walking may offer extra is one of the simplest and most effective ways to boost overall health, as it can offer benefits like reduced mortality, improved blood sugar levels and better heart health. Studies suggest that even light walking can have a positive impact on outcomes like reducing blood pressure. But most research on walking focuses on middle-to-high-income white populations, leaving gaps in understanding how walking impacts low-income and racial minority groups. These populations often face unique challenges, such as limited access to safe walking spaces, higher exposure to pollution and barriers to healthcare, all of which can contribute to higher mortality rates. To address the lack of research on walking in underserved communities, scientists used data from the Southern Community Cohort Study (SCCS) to explore how daily walking impacts overall and specific causes of mortality, and the results were published in the American Journal of Prevention Medicine. How Was The Study Conducted? This study enrolled about 85,000 participants aged 40 to 79 from the Southern Community Cohort Study (SCCS), focusing on individuals who had not undergone cancer treatment in the year prior to joining. The SCCS is a large study focused on understanding why racial disparities exist in cancer and other chronic diseases, particularly in low-income populations. What makes this study unique is that over half of the participants reported earning less than $15,000 a year, and about two-thirds of them are Black. This diverse group offers a rare chance to examine how daily walking affects health outcomes in low-income, racially diverse populations. At the start of the study, participants completed detailed questionnaires covering their daily walking habits, lifestyle choices and medical history. Participants reported how much time they spent walking each day, distinguishing between slow walking (e.g., walking the dog or light exercise) and fast walking (e.g., brisk walking or climbing stairs). They could report anywhere from 0 to 720 minutes per day, and their responses were grouped into four categories: no walking, less than 30 minutes, 30-60 minutes and more than 60 minutes. These categories align with health guidelines recommending at least 30 minutes of daily activity. The study also explored fast walking in smaller increments (e.g., 15-minute intervals). In addition to walking, the study measured five key lifestyle factors linked to mortality: smoking, alcohol use, physical activity, sedentary behavior and diet quality. These factors were combined into a composite lifestyle score, with higher scores indicating healthier lifestyles. The study tracked participants' vital status and causes of death through the National Death Index until December 31, 2022. Deaths were categorized into major causes, including cardiovascular disease (CVD), cancer, other diseases and external causes like accidents. Specific types of CVD, such as heart disease and stroke, were also analyzed due to their prevalence. This comprehensive approach allowed researchers to examine how daily walking and lifestyle factors influence overall and cause-specific mortality in a diverse, low-income population. What Did This Study Find? The study found that, among the studied population, fast walking was significantly linked to lower overall mortality, while slow walking showed only a slight, non-significant benefit. For those who walked slowly for more than three hours a day, there was a 4% lower risk of death, but this result wasn't strong enough to be considered statistically significant. On the other hand, fast walking showed clear benefits; even just 15 minutes a day was associated with a 19% lower risk of death. When researchers accounted for other lifestyle factors like diet, smoking and physical activity, the benefits of fast walking remained strong, while the slight benefits of slow walking became even less noticeable. Overall, fast walking stood out as a simple and effective way to reduce the risk of death. Additional analyses confirmed the findings, showing consistent results for the link between time spent walking (both slow and fast) and overall mortality, even when including participants who died within the first two years. Fast walking showed similar patterns of reduced risk across all specific causes of death, but the strongest benefits were seen for cardiovascular disease (CVD). People who walked fast for more than 60 minutes a day had a 20% lower risk of dying from CVD compared to those who didn't walk at all. Within CVD, the biggest reductions in risk were seen for heart diseases, particularly ischemic heart disease and heart failure. Interestingly, the benefits of fast walking were independent of other physical activities, meaning fast walking provided its own unique health boost. Even for individuals who were already active, those who walked fast for more than 60 minutes a day saw additional benefits, with a 16% lower risk of death compared to those who didn't walk fast at all. There are a few limitations to keep in mind when interpreting these results. First, since participants reported their own daily walking habits, some may have included other activities like climbing stairs, which could lead to some misclassification. Second, physical activity data was only collected at the start of the study, so it wasn't possible to see how changes in activity over time might affect the results. Additionally, because this was an observational study, it's hard to completely rule out other factors, like pre-existing health conditions or unmeasured influences, that could have impacted the findings. How Does This Apply To Real Life? This study highlights that walking, especially fast walking, can be a powerful tool for improving health and reducing the risk of death, even with just 15 minutes a day. For people who may not have access to gyms or structured exercise programs, walking offers an easy, low-cost way to stay active. The findings are particularly important for underserved communities, where barriers like limited access to safe walking spaces or healthcare can make it harder to prioritize health. The study also emphasizes that fast walking has unique benefits, even for those who are already active or engage in other forms of exercise. This means that adding a brisk walk to your daily routine can complement other activities and provide an extra health boost. Whether it's a quick walk around the block, climbing stairs at work, or picking up the pace while walking the dog, these small changes can add up. The key takeaway? You don't need fancy equipment or hours of free time; just lace up your shoes, pick up the pace and let your feet do the work for your health. Our Expert Take This study published in the American Journal of Prevention Medicine highlights that even small amounts of fast walking (just 15 minutes a day) can make a meaningful difference in overall health and longevity. For those where access to gyms or safe exercise spaces may be limited, this study offers an encouraging and accessible way to improve health outcomes. The findings also underscore the importance of making walking a part of daily life. Whether it's a brisk walk to the store, a quick loop around the neighborhood or simply picking up the pace during your usual routine, fast walking is a simple, low-cost activity with big health payoffs. Grab your sneakers, step outside and start reaping the benefits—your heart (and the rest of your body) will thank you. Read the original article on EATINGWELL
