We knew we wished this checklist to replicate China’s emergence as a worldwide vitality superpower, and we ended up together with two Chinese language companies in key industries: renewables and batteries.
In 2024, China accounted for the highest 4 wind turbine makers worldwide. Envision was within the second spot, with 19.3 gigawatts of latest capability added final 12 months. However the firm isn’t restricted to wind; it’s working to assist energy heavy industries like metal and chemical substances with know-how like inexperienced hydrogen.
Batteries are additionally a sizzling business in China, and we’re seeing progress in tech past the lithium-ion cells that at present dominate EVs and vitality storage on the grid. We symbolize that business with HiNa Battery Know-how, a number one startup constructing sodium-ion batteries, which may very well be cheaper than at present’s choices. The corporate’s batteries are already being utilized in electrical mopeds and grid installations.
2. Vitality demand from knowledge facilities and AI is on everybody’s thoughts, particularly within the US.
One other pattern we seen this 12 months was a fixation on the rising vitality demand of information facilities, together with large deliberate devoted services that energy AI fashions. (Right here’s one other nudge to take a look at our Energy Hungry sequence on AI and vitality, in case you haven’t explored it already.)
Even when their know-how has nothing to do with knowledge facilities, corporations try to point out how they are often useful on this age of rising vitality demand. Some are signing profitable offers with tech giants that would present the cash wanted to assist deliver their product to market.
Kairos Energy hopes to be one such vitality generator, constructing next-generation nuclear reactors. Final 12 months, the corporate signed an settlement with Google that may see the corporate purchase as much as 500 megawatts of electrical energy from Kairos’s first reactors by means of 2035.

The brand new Basic Contact software program is meant to allow exact, untethered haptics. Supply: Basic XR
Tactile suggestions could possibly be helpful in a number of functions, however the sensors historically require tethers. Basic XR immediately introduced the provision of Basic Contact, a wi-fi platform brining haptics past healthcare into industries together with robotics, industrial coaching, automotive, aerospace, retail, and gaming.
“Contact is the lacking dimension in human–machine interplay, and precision kinesthetic haptics lastly unlocks its full potential by going wi-fi,” stated Richard Vincent, founder and CEO of Basic XR. “Basic Contact removes the bodily tether, giving customers the mobility and efficiency parity they should prepare, discover, and function in methods by no means earlier than potential.”
Basic XR stated its immersive applied sciences together with augmented, blended, and digital actuality (AR/MR/VR), haptics, net, and app to assist medical groups prepare and undertake advanced procedures. The London-based firm, previously generally known as FundamentalVR, claimed that its platform can cut back onboarding time by greater than 60%, increase surgical accuracy by 44%, and enhance gross sales efficiency by 22%.
Basic XR stated healthcare organizations use its spatial applied sciences to “speed up ability acquisition, enhance outcomes, and energy the following era of digital surgical procedure.” They’ve delivered greater than 50,000 classes in over 30 nations, it added.
Basic Contact makes use of client-server mannequin
Basic XR stated its lifelike force-feedback simulations have helped prepare surgeons and clinicians for years. With the device-agnostic Basic Contact software program, the corporate stated it’s “chopping the wires on haptic expertise and increasing entry to precision kinesthetic haptics structure throughout a variety of industries the place freedom of motion, constancy, and ease of setup are crucial.”
Basic Contact is constructed on a wi-fi structure that decouples haptic simulations from visible simulation and person interfaces. Historically, high-fidelity kinethetic haptics required a direct wire connection to a desktop pc, limiting motion and adoption, in keeping with Basic XR.
The brand new providing solves this with a shopper–server mannequin that permits mobility, scalability, and sub-100ms latency. Basic XR listed some specs:
Basic Contact: The software program runs on a devoted server or “haptic engine.” It interprets serialized simulations despatched from the headset or enter gadget and interprets person actions equivalent to button clicks or scene modifications into practical haptic suggestions.
Community layer: A peer-to-peer communication layer connects the headset or enter gadget and server, guaranteeing low-latency, bi-directional knowledge trade for real-time drive suggestions, stated the corporate.
Haptic server: A single-board pc or embedded gadget hosts the software program. It connects on to haptic gadgets equivalent to gloves, arms, pens, or fits and is designed to be embedded into them over time.
Output gadgets: Shoppers embrace XR headsets like Apple Imaginative and prescient Professional and Meta Quest, robotic platforms equivalent to Boston Dynamics‘ Spot quadruped, or gaming peripherals. They deal with the visible rendering and talk wirelessly with the haptic server for synchronized suggestions.
“With this structure, Basic Contact turns into a plug-and-play layer for wi-fi haptics, enabling builders, trainers, and operators to create wealthy tactile simulations that have been beforehand unimaginable with out wires,” stated Basic XR.
Basic XR reaches throughout industries
“Basic Contact is ready to redefine how people work together with machines throughout industries, unlocking new prospects the place the sense of contact and simulated sensations remodel experiences and improve efficiency,” Basic XR asserted.
The corporate stated that teleoperators of robots and drones can “really feel what the robotic feels” whereas controlling machines in hazardous or distant environments, from nuclear amenities to deep-sea missions and area exploration. The software program may additionally assist with imitation studying for coaching AI fashions and humanoid robots.
Basic XR additionally famous that its high-fidelity kinesthetic haptics can feed digital twins and simulations operating on standalone XR gadgets, “lowering friction and price” whereas rising precision. The simulations can then be utilized in industrial coaching, healthcare, and automotive and aerospace instruction.
As well as, wi-fi haptics might help guarantee operator security for emergency, protection, and industrial functions, equivalent to search and rescue, explosive ordnance disposal (EOD), and dangerous materials dealing with with cell manipulators. Lastly, Basic Contact may benefit artists and avid gamers, stated Basic XR.
“The launch of Basic Contact marks an important step within the evolution of immersive expertise,” the corporate stated. “By eradicating the tether, Basic XR is delivering whole person freedom, high-fidelity drive suggestions, and broad platform compatibility, ushering in a brand new period of human–machine interplay that stretches throughout drugs, business, mobility, commerce, and leisure.”
Apple seems to be winding down assist of Clips, with the corporate eradicating Clips from the App Retailer and saying it is going to not be making any updates.
In a assist web page on the Apple web site, the corporate says that as of October 10, Clips is not out there for brand new customers to obtain, however present customers can proceed to make use of the app on present or earlier variations of iOS and iPadOS. Current customers also can re-download the app from their Apple account if wanted.
With out updates, it is going to most likely develop into tougher to make use of Clips over time, so Apple is encouraging customers to obtain their Clips movies (with or with out added results) to their photograph library, to allow them to watch and edit the movies utilizing different apps.
Launched in 2017, Clips seemed to be Apple’s reply to Snapchat and Instagram Tales — it wasn’t a social community, however it allowed customers to sew collectively images and movies with filters, emojis, and music.
Early on, TechCrunch’s Brian Heater described Clips’ video modifying capabilities as easy to a fault and instructed that the app may permit Apple to showcase its {hardware} and software program capabilities whereas providing customers a path out of then on-the-rise social ecosystems.
MacRumors reviews that whereas Apple upgraded Clips with new options after launch, updates lately have been restricted to bug fixes.
Apple followers on Reddit appeared unsurprised by the information, saying they’d solely tried the app years in the past or by no means heard of it in any respect. Plus, an app like Clips — constructed round actual footage shot by actual folks — may really feel a bit old style when in comparison with Sora, OpenAI’s generative AI video app that lately hit 1 million downloads.
The controversial preservation order requiring OpenAI to indefinitely maintain data of its ChatGPT information has been terminated. Federal choose Ona T. Wang filed a brand new order on October 9 that frees OpenAI of an obligation to “protect and segregate all output log information that will in any other case be deleted on a going ahead foundation.”
The case kicked off in late 2023, with the New York Occasions suing OpenAI for copyright infringement, alleging that the AI big skilled its fashions with the information outlet’s mental property with out correct compensation. In Could of this yr, OpenAI was ordered to retain all of its chat logs in order that the NYT might examine claims of copyright violation. In response, OpenAI appealed the court docket order, arguing that the preservation order was an “overreach” and dangers its customers’ privateness.
Nevertheless, this newest choice means the AI big not has to protect chat logs as of September 26, apart from some. The choose within the case stated that any chat logs already saved beneath the earlier order would nonetheless be accessible and that OpenAI is required to carry on to any information associated to ChatGPT accounts which were flagged by the NYT. Transferring ahead, the NYT is allowed to develop the variety of flagged customers, because it continues to comb via OpenAI’s preserved data.

We just lately had a dialogue on the workplace and wished to get your enter too – which dimensions ought to the Telephone Finder use for foldable telephones if you end up trying to find particular dimensions (thickness, width, top)?
First, let’s study the difficulty. We listing two thickness dimensions for foldables – one for when the telephone is opened and one for when it’s closed. The closed thickness is round double the open thickness, however that’s not fairly correct as a result of hinges add a bit additional and that differs from telephone to telephone.
Equally, there are two numbers for the width on book-style foldables and the peak on flip foldables, relying on whether or not the telephone is folded or not. Once more, one quantity is near double the opposite quantity, however hinges complicate issues.
Foldable telephones change dimension, which complicates issues
Right here is how the Telephone Finder works proper now. Whenever you use the sliders for thickness, width and top, you get outcomes primarily based on the telephone’s unfolded state. Is that this one of the simplest ways or ought to we change issues round?
For instance, the primary sub-10mm foldable was a significant milestone. However because it stands, there isn’t any simple technique to discover foldables which might be beneath 10mm when folded – in case you set the slider at 10mm, all of them present up as a result of the filter appears on the unfolded thickness, which could not be what you anticipate.
You may’t simply drag the slider to 5mm (half the specified thickness) both. “Folded thickness is roughly double the unfolded thickness” is an okay rule of thumb, however in apply it doesn’t work very properly for filtering search outcomes.
Ebook-style foldables now rival bar telephones
What about width and top, for book-style and flip foldables, respectively? The unfolded dimensions are necessary as a result of they provide you an concept of how the telephone will slot in your hand. Folded dimensions are necessary as a result of they provide you an concept of how the telephone will slot in your pocket.
So, ought to Telephone Finder have a look at folded or unfolded dimensions when looking out? Or possibly the folded thickness and unfolded width/top, relying on the model of foldable? This might get fairly complicated, although, because the dimension used within the search will fluctuate from telephone to telephone – particularly whenever you get a mixture of foldables and common telephones. What do you suppose? Vote beneath and share your ideas within the feedback.
In case you ever end up in Battery Park Metropolis in Decrease Manhattan, flip down Vesey Road towards North Finish Avenue. You’ll arrive at one thing uncommon: a group of stones, soil and moss, artfully organized to look over the Hudson River.
It’s the Irish Starvation Memorial, a chunk of public art work that commemorates the devastating Irish famine of the mid-Nineteenth century, which led to the deaths of at the very least 1 million individuals and completely altered Eire’s historical past, forcing the emigration of thousands and thousands extra Irish to cities like New York.
The Irish famine is uncommon in how closely commemorated it’s, with greater than 100 memorials in Eire itself and world wide. Different famines, together with ones that killed way more individuals just like the 1943 Bengal famine in India or China’s 1959–’61 famine, largely go with out main public memorials.
It shouldn’t be this manner. Researchers estimate that since 1870 alone, roughly 140 million individuals have died of famine. Return additional in historical past, and famines turn into ever extra widespread and ever extra lethal. One horrible famine in northern Europe within the early 14th century killed as a lot as 12 % of the complete area’s inhabitants in a handful of years. Even outdoors famine years, the provision of meals was a continuing strain on the human inhabitants.
So, whereas starvation continues to be far too widespread immediately, famines themselves are far, far rarer — and are more likely to be the results of human failures than of crop failures. It’s one of many nice human achievements of the fashionable age, one we too usually fail to acknowledge.
The information will get even higher: By the newest tallies, the world is on monitor to develop extra grain this yr than ever earlier than. The UN’s Meals and Agriculture Group (FAO) initiatives file ranges of manufacturing of world cereal crops like wheat, corn and rice within the 2025–’26 farming season. Hidden inside that information is one other quantity that’s simply as necessary: a worldwide stocks-to-use ratio round 30.6 % — which means the world is producing almost a 3rd extra of those foundational crops than it’s at the moment utilizing.
The US Division of Agriculture’s August outlook factors the identical means: a file US corn crop, and much more importantly, a file yield, or the quantity of crop grown per acre of land. That final quantity is particularly necessary: the extra we are able to develop on one acre, the much less land we have to farm to satisfy international demand for meals. The FAO Meals Value Index, which tracks the price of a global basket of meals commodities, is up a bit this yr, however is sort of 20 % beneath the height through the early months of the struggle in Ukraine.
Zoom out, and the lengthy arc of enchancment is starker. Common energy obtainable per particular person worldwide have been climbing for many years, from roughly 2,100 to 2,200 kcal/day within the early Nineteen Sixties to only underneath 3,000 kcal/day by 2022. In the meantime, cereal yields have roughly tripled since 1961. These two strains — extra meals per particular person, extra grain per hectare — have helped carry us out of the outdated Malthusian shadow.
As with farming, begin on the seed. The short-straw wheat and rice of the Inexperienced Revolution made essentially the most of fertilizer, hybrid seeds added a yield bonus, genetically modified crops arrived within the ’90s, and now CRISPR lets breeders make surgical edits to a plant’s personal genes.
When you’ve obtained the seeds, you want fertilizer. The world was as soon as depending on pure sources of nitrogen that there was a mad sprint to harvest nitrogen-rich dried chicken poop or guano within the Nineteenth century, however in 1912, Fritz Haber and Carl Bosch developed their course of for creating artificial nitrogen for fertilizer. The Haber-Bosch course of is so necessary that half of immediately’s meals possible is dependent upon it.
Now add water. The place as soon as most farmers needed to rely upon the climate to water their vegetation, irrigated farmland has greater than doubled since 1961, with that land offering some 60 % of the world’s cereal crops, and in flip half the world’s energy. Extremely productive farmland like California’s Central Valley could be unimaginable with out intensive irrigation.
And at last, get the meals to individuals. Higher logistics and international commerce has created a system that may shuffle energy from surplus to deficit when one thing goes flawed regionally.
However this doesn’t imply the system is ideal — or perpetual.
Why will we nonetheless have starvation?
Whereas the world routinely grows greater than sufficient energy, wholesome diets stay out of attain for billions. The World Financial institution estimates round 2.6 billion individuals can’t afford a nutritious diet. That quantity has fallen barely from previous years, however the state of affairs is getting worse in sub-Saharan Africa.
When famines do happen immediately, the causes are typically way more political than they’re agronomical. The horrible famines in Gaza and Sudan, the place greater than 25 million persons are prone to going hungry, are so terrible exactly as a result of they present the consequences of man-made entry failures amid a world of abundance. (Although in Gaza, at the very least, the obvious peace deal is lastly offering hope for reduction.)
One other risk to progress in opposition to famine additionally has a political dimension: local weather change. Although primary crop harvests and yields have to this point confirmed largely resilient in opposition to the consequences of warming, local weather scientists warn that dangers to meals safety will rise with temperatures, particularly through warmth, drought, and compound disasters that may hit a number of breadbaskets without delay. The excellent news is that adaptation — smarter agronomy, stress-tolerant varieties, irrigation effectivity — can cushion losses as much as round 2 levels Celsius. However our choices might slender past that.
A extra self-inflicted wound might come through commerce restrictions. One of many worst current meals value crises, in 2007 and 2008, occurred much less due to manufacturing failures than political ones, as governments restricted exports, main to cost spikes that hit the poor hardest. That’s a worrying precedent given the Trump administration’s renewed push for tariffs and commerce obstacles.
The Irish Starvation Memorial is a reminder of how horrible shortage might be — and the way far we’ve come. After hundreds of years when starvation was a given, humanity has constructed a meals system that, for all its flaws, feeds eight billion and retains setting harvest data. For all of the challenges we face immediately and that will come tomorrow, that’s a narrative value commemorating.

If you’re spinning up your Amazon OpenSearch Service area, it is advisable to work out the storage, occasion varieties, and occasion depend; determine the sharding methods and whether or not to make use of a cluster supervisor; and allow zone consciousness. Usually, we take into account storage as a tenet for figuring out occasion depend, however not different parameters. On this publish, we provide some suggestions primarily based on T-shirt sizing for log analytics workloads.
Log analytics and streaming workload traits
If you use OpenSearch Service on your streaming workloads, you ship knowledge from a number of sources into OpenSearch Service. OpenSearch Service indexes your knowledge in an index that you simply outline.
Log knowledge naturally follows a time sequence sample, and subsequently a time-based indexing technique (each day or weekly indexes) is really useful. For environment friendly administration of log knowledge, you have to implement time-based index patterns and set retention intervals. You additional outline time slicing and a retention interval for the information to handle its lifecycle in your area.
For illustration, take into account that you’ve a knowledge supply producing a steady stream of log knowledge, and also you’ve configured a each day rolling index and set a retention interval of three days. Because the logs arrive, OpenSearch Service creates an index per day with names like stream1_2025.05.21, stream1_2025.05.22, and so forth. The prefix stream1_* is what we name an index sample, a naming conference that helps group-related indexes.
The next diagram reveals three major shards for every each day index. These shards are deployed throughout three OpenSearch Service knowledge situations, with one duplicate for every major shard. (For simplicity, the diagram doesn’t present that major and duplicate shards are at all times positioned on completely different situations for fault tolerance.)
When OpenSearch Service processes new log entries, they’re despatched to all related major shards and their replicas within the energetic index, which on this instance is simply right this moment’s index as a result of each day index configuration.
There are a number of necessary traits of how OpenSearch Service processes your new entries:
Complete shard depend – Every index sample could have a D * P * (1 + R) complete shards, the place D represents retention in days, P represents major shards, and R is the variety of replicas. These shards are distributed throughout your knowledge nodes.
Energetic index – Time slicing signifies that new log entries are solely written to right this moment’s index.
Useful resource utilization – When sending a _bulk request with log entries, these are distributed throughout all shards within the energetic index. In our instance with three major shards and one duplicate per shard, that’s a complete of six shards processing new knowledge concurrently, requiring 6 vCPUs to effectively deal with a single _bulk request.
Equally, OpenSearch Service distributes queries throughout the shards for the indexes concerned. If you happen to question this index sample throughout all 3 days, you’ll have interaction 9 shards, and wish 9 vCPUs to course of the request.
This may get much more sophisticated once you add in additional knowledge streams and index patterns. For every extra knowledge stream or index sample, you deploy shards for every of the each day indexes and use vCPUs to course of requests in proportion to the shards deployed, as proven within the previous diagram. If you make concurrent requests to a couple of index, every shard for all of the indexes concerned should course of these requests.
Cluster capability
Because the variety of index patterns and concurrent requests will increase, you possibly can rapidly overwhelm the cluster’s assets. OpenSearch Service contains inner queues that buffer requests and mitigate this concurrency demand. You possibly can monitor these queues utilizing the _cat/thread_pool API, which reveals queue depths and helps you perceive when your cluster is approaching capability limits.
One other complicating dimension is that the time to course of your updates and queries is determined by the contents of the updates and queries. As requests are available, the queues are filling on the charge you might be sending them. They’re draining at a charge that’s ruled by the obtainable vCPUs, the time they tackle every request, and the processing time for that request. You possibly can interleave extra requests if these requests clear in a millisecond than in the event that they clear in a second. You should utilize the _nodes/stats OpenSearch API to observe common load in your CPUs. For extra details about the question phases, consult with A question, or There and Again Once more on the OpenSearch weblog.
If you happen to see the queue depths growing, you might be transferring right into a “warning” space, the place the cluster is dealing with load. However in the event you proceed, you can begin to exceed the obtainable queues and should scale so as to add extra CPUs. If you happen to begin to see load growing, which is correlated with queue depth growing, you might be additionally in a “warning” space and may take into account scaling.
Suggestions
For sizing a site, take into account the next steps:
Decide the storage required – Complete storage = (each day supply knowledge in bytes × 1.45) × (number_of_replicas + 1) × variety of days retained. This accounts for the extra 45% overhead on each day supply knowledge, damaged down as follows:
10% for bigger index dimension than supply knowledge.
5% for working system overhead (reserved by Linux for system restoration and disk defragmentation safety).
20% for OpenSearch reserved area per occasion (section merges, logs, and inner operations).
10% for extra storage buffer (minimizes affect of node failure and Availability Zone outages).
Outline the shard depend – Approximate variety of major shards = storage dimension required per index / desired shard dimension. Spherical as much as the closest a number of of your knowledge node depend to keep up even distribution. For extra detailed steering on shard sizing and distribution methods, consult with “Amazon OpenSearch Service 101: What number of shards do I want” For log analytics workloads, take into account the next:
Really useful shard dimension: 30–50 GB
Optimum goal: 50 GB per shard
Calculate CPU necessities – Really useful ratio is 1.25 vCPU:1 Shard for decrease knowledge volumes. Greater ratios are really useful for bigger volumes. Goal utilization is 60% common, 80% most.
Select the proper occasion kind – Think about the next primarily based in your nodes:
Let’s take a look at an instance for area sizing. The preliminary necessities are as follows:
Every day log quantity: 3 TB
Retention interval: 3 months (90 days)
Duplicate depend: 1
We make the next occasion calculation.
The next desk recommends situations, quantity of supply knowledge, storage wanted for 7 days of retention, and energetic shards primarily based on the previous pointers.
