Even in the event you’ve constructed one of many world’s most superior insect-inspired micro air autos (MAVs), it in the end will not be that helpful if it will possibly’t stick touchdown. That is why scientists at Harvard College have now given their RoboBee a set of lengthy, jointed legs very similar to these of the crane fly.

For these of you who’re unfamiliar with the RoboBee, it is a bee-inspired robotic that flies by flapping a tiny pair of artificial-muscle-equipped wings. It has a wingspan of lower than 3 cm (1.2 in) and weighs solely a few tenth of a gram … though it is linked to an influence supply and a microprocessor by way of a wire.

That stated, future variations might in the end be absolutely self-contained. The truth is, there’s already one variant that is solar-powered.

Though different incarnations of the little robotic have confirmed able to feats corresponding to flying underwater and perching on overhangs, the bottom mannequin has by no means been that nice at merely touchdown on flat (or different) surfaces. It is because vortices created by its flapping wings trigger air turbulence as they turn out to be confined in opposition to the bottom, which may in flip knock the bot off stability.

“Beforehand, if we have been to go in for a touchdown, we’d flip off the automobile just a little bit above the bottom and simply drop it, and pray that it’s going to land upright and safely,” says engineering graduate scholar Christian Chan, who led the mechanical redesign of the robotic.

The RoboBee’s 4 new crane-fly-inspired legs are lengthy and versatile sufficient that they will all safely make contact with the bottom earlier than the bot’s major physique turns into affected by the floor impact turbulence.

Moreover, a brand new management algorithm helps information the robotic extra easily to the bottom, as an alternative of permitting it to “simply drop.”

Human civilization might sacrifice itself on the altar of comfort. We expose our each transfer to surveillance by governments and entrepreneurs as a result of our cell telephones are so handy we are able to’t do with out them. We use billions of single use plastic bottles as a result of they’re simply so darn handy. You slurp your beverage of selection, then toss the bottle away. Out of sight, out of thoughts. All of them get recycled, don’t they?

Truly, no, they don’t. In response to The Ocean Cleanup Undertaking, almost 2 million metric tons of plastic waste enters the oceans yearly from seashores and waterways. A lot of it’s single use beverage bottles, cups, and straws. As soon as they enter the oceans, they’ll take a whole lot of years to interrupt down, throughout which era they degrade into microplastics that get ingested by marine crops and animals. Microplastics have been discovered within the deepest components of ocean and the tops of the very best mountains. They’re in our bloodstreams, in breast milk, and in human placentas.

And but, comfort wins out over frequent sense persistently. A number of years in the past, Bea Perez, head of sustainability for Coca-Cola, advised the World Financial Discussion board in Davos, Switzerland, the corporate has no intention of abandoning single use plastic bottles. Why? It’s all the purchasers’ fault, apparently. They just like the comfort of light-weight, recloseable bottles and the corporate is afraid to disclaim its prospects what they need as a result of it’d lose market share. Is market share a purpose to degrade the setting? If you’re Coca-Cola, apparently the reply is sure.

An Various To Single Use Plastic

On April 9, 2025, the journal Scientific Adviser printed a paper by researchers in Japan with this entertaining title — “Absolutely round shapable clear paperboard with closed-loop recyclability and marine biodegradability throughout shallow to deep sea.” The crucial phrase within the title is “clear.” Till now, solely plastics derived from fossil gasoline shares have been clear sufficient for use within the meals trade. Consider Saran Wrap and different movies utilized in packaging. Beverage containers are normally clear for related causes.

The energy and sturdiness of plastic is difficult to beat, however those self same properties are precisely what make it an environmental nuisance. It lingers for a whole lot of years in soils and waterways. And whereas biodegradable plastics or plastic options exist, they typically carry out poorly in actual world use.

In response to Anthropocene Journal, researchers in Japan have discovered a technique to make a brand new paper-based materials that could possibly be a super alternative for some single use plastics. The millimeter thick paperboard behaves like plastic, however solely when wanted. It’s robust, clear, and shapeable, plus it will possibly maintain boiling water. However its most necessary characteristic is that it full degrades in lower than a yr as soon as it settles to the ocean ground.

Researchers from the Japan Company for Marine-Earth Science and Know-how have been in a position to strike a stability between efficiency and degradability with their new paperboard materials which they name tPB — shorthand for “clear paperboard.” They began with cellulose, the molecule that makes up plant cell partitions. Along with getting used to make paper, cellulose can even used to make clear cellophane sheets.

However cellophane movies can solely be made lower than 0.05 mm thick as a result of the chemical substances used to solidify the cellulose answer don’t work with thicker sheets. The Japanese analysis group discovered a workaround to that drawback by making a thick cellulose hydrogel. The method entails dissolving cellulose in an aqueous lithium bromide answer. Drying the hydrogel gave clear cellulose sheets which might be one millimeter thick. The researchers then formed these sheets to make cups and straws. A cup comprised of the clear materials might maintain boiled water for over 3 hours with no leakage. When the researchers coated the cup with a plant-derived fatty acid salt, it grew to become utterly waterproof.

To check the degradability of the fabric in case of unintended launch into the ocean, the researchers submerged paperboard sheets at websites situated at 4 completely different ocean websites of various depths. One was close to a port at a depth of two meters, two have been in waters round 750 and 850 meters deep, and the final one was submerged within the ocean at a depth of over 5,550 meters. The checks confirmed the tPB materials totally decomposed in 300 days at deep ocean depths. The degradation was even sooner in shallower depths due to hotter temperatures. Right here is the summary to the analysis examine:

To mitigate marine air pollution from single use plastics, it’s essential to transition to next-generation commodity supplies which might be derived from biomass and are recyclable and marine biodegradable even at abyssal depths in case of the unintended launch to the ocean. Right here, we develop an optically clear millimeter-thick paperboard referred to as clear paperboard (tPB) by means of dissolution and coagulation of cellulose. The tPB is made totally of pristine cellulose and compositionally an identical to paper. A cup-shaped tPB can maintain just-boiled water with out an inside movie coating due to its excessive moist tensile properties and anisotropic thermal properties. As well as, the spent tPB is materials recyclable in a closed system, the place all chemical substances and water are additionally recyclable. Moreover, the marine biodegradability of tPB throughout shallow to abyssal depths is confirmed by on-site degradation checks and metagenomic analyses. Therefore, tPB is predicted to function a key totally round commodity materials in sustainable societies of the longer term.

Is that this an enormous deal? Sure it’s. International plastic manufacturing reached 400 million tons in 2022, with packaging and single use plastics accounting for a considerable quantity of that whole. The ensuing waste leads to landfills, incinerators, or the setting, the place it contributes to environmental air pollution. Plastic manufacturing releases planet warming greenhouse gases and different harmful pollution.

The emphasis on curbing plastic use is a mirrored image of world acknowledgement that recycling or repurposing current plastics simply received’t work. International plastic manufacturing rose almost 230-fold between 1950 and 2019, to greater than 400 million tons a yr, and is predicted to quadruple from present ranges by 2050. An estimated 40% of that’s single-use plastic, which makes up the majority of the world’s plastic waste. If there actually is a viable different, that’s excellent news for the Earth.

IBM X-Drive: Stealthy assaults on the rise, toolkits concentrating on AI emerge



Final yr, X-Drive predicted that after AI applied sciences “set up market dominance—when a single expertise approaches 50% market share or when the market consolidates to a few or fewer applied sciences—attackers shall be incentivized to spend money on assault toolkits” that concentrate on AI fashions and options. “Are we there but? Not fairly, however adoption is rising,” the report acknowledged. “The proportion of corporations integrating AI into a minimum of one enterprise operate has dramatically elevated to 72% in 2024, up 55% from within the earlier yr.”

“New applied sciences, resembling gen AI, create new assault surfaces. Safety researchers are sprinting to search out and assist repair vulnerabilities earlier than attackers do. We count on vulnerabilities in AI frameworks to change into extra frequent over time, such because the distant code execution vulnerability X-Drive present in a framework for constructing AI brokers,” IBM acknowledged. “Just lately, an energetic assault marketing campaign concentrating on a extensively used open supply AI framework was found, affecting schooling, cryptocurrency, biopharma, and different sectors. Weaknesses in AI expertise translate into vulnerabilities for attackers to use.”

Further findings from X-Drive embrace:

  • Reliance on legacy expertise and sluggish patching cycles show to be an everlasting problem for crucial infrastructure organizations as cybercriminals exploited vulnerabilities in additional than one-quarter of incidents that IBM X-Drive responded to on this sector final yr. In reviewing the frequent vulnerabilities and exposures (CVEs) most talked about on darkish internet boards, IBM X-Drive discovered that 4 out of the highest ten have been linked to classy menace actor teams, together with nation-state adversaries, escalating the chance of disruption, espionage and monetary extortion.
  • Ransomware assaults proceed their scourge. “Evaluation of darkish internet knowledge reveals a 25% enhance in ransomware exercise year-over-year. Adoption of a cross-platform strategy to ransomware, supporting each Home windows and Linux, additionally seems to be the norm amongst ransomware menace teams—increasing assault surfaces. Though ransomware is being overshadowed by different ways, it stays a significant menace vector. Essentially the most harmful development in ransomware is the usage of a number of extortion ways,” IBM acknowledged. Ransomware includes practically one-third (28%) of malware incident response instances and 11% of safety instances, representing a decline during the last a number of years.
  • Whereas phishing assaults dropped total, IBM discovered an 84% spike in phishing emails delivering infostealers in 2024, and early 2025 knowledge reveals a fair greater enhance (180%). These stolen credentials could also be utilized in follow-on, identity-based assaults. 
  • With the elevated effectiveness of endpoint detection and response (EDR) options detecting backdoor intrusion efforts by way of phishing, menace actors have shifted to utilizing phishing as a shadow vector to ship infostealer malware. In 2024, X-Drive noticed an 84% enhance in infostealers delivered by way of phishing. There was additionally a 12% year-over-year enhance of infostealer credentials on the market on the darkish internet, suggesting elevated utilization. Extra attackers stole knowledge (18%) than encrypted (11%) it final yr as superior detection applied sciences and elevated legislation enforcement efforts stress attackers to pivot to sooner exit paths.
  • In collaboration with Pink Hat Insights, IBM X-Drive discovered that greater than half of Pink Hat Enterprise Linux clients’ environments had a minimum of one crucial CVE unaddressed, and 18% confronted 5 or extra vulnerabilities. On the identical time, IBM X-Drive discovered essentially the most energetic ransomware households (e.g., Akira, Clop, Lockbit, and RansomHub) at the moment are supporting each Home windows and Linux variations of their ransomware. 
  • For the fourth consecutive yr, manufacturing was essentially the most attacked business. Dealing with the very best variety of ransomware instances final yr, the return on funding for encryption holds sturdy for this sector attributable to its extraordinarily low tolerance for downtime.

NTT Analysis Launches New Physics of Synthetic Intelligence Group at Harvard

When a mum or dad is educating their younger youngster to narrate to the world, they train by associations and the identification of patterns. Take the letter S, for instance. Mother and father present their youngster sufficient examples of the letter and earlier than lengthy, they may be capable of establish different examples in contexts the place steering will not be lively; college, a ebook, a billboard.

A lot of the ever-emerging synthetic intelligence (AI) know-how was taught the identical means. Researchers fed the system appropriate examples of one thing they needed it to acknowledge, and like a younger youngster, AI started recognizing patterns and extrapolating such information to contexts it had by no means earlier than skilled, forming its personal “neural community” for categorization. Like human intelligence, nevertheless, consultants misplaced monitor of the inputs that knowledgeable AI’s choice making. 

The “black field downside” of AI thus emerges as the truth that we don’t totally perceive how or why an AI system makes connections, nor the variables that play into its choices. This concern is particularly related when in search of to enhance programs’ trustworthiness and security and establishing the governance of AI adoption. 

From an AI-powered car that fails to brake in time and hurts pedestrians, to AI-reliant well being tech gadgets that help docs in diagnosing sufferers, and biases exhibited by AI hiring screening processes, the complexity behind these programs has led to the rise of a brand new area of examine: the physics of AI, which seeks to additional set up AI as a instruments for people to realize larger understanding. 

Now, a brand new unbiased examine group will handle these challenges by merging the fields of physics, psychology, philosophy and neuroscience in an interdisciplinary exploration of AI’s mysteries.

The newly-announced Physics of Synthetic Intelligence Group is a spin-off of NTT Analysis’s Physics & Informatics (PHI) Lab, and was unveiled at NTT’s Improve 2025 convention in San Francisco, California final week. It’ll proceed to advance the Physics of Synthetic Intelligence method to understanding AI, which the workforce has been investigating for the previous 5 years. 

Dr. Hidenori Tanaka, who has a PhD in Utilized Physics & Pc Science and Engineering from Harvard College, will lead the brand new analysis group, constructing on his earlier expertise in NTT’s Clever Techniques Group and CBS-NTT’s AI Analysis program within the physics of intelligence at Harvard.

“As a physicist I’m excited concerning the topic of intelligence as a result of, mathematically, how are you going to consider the idea of creativity? How are you going to even take into consideration kindness? These ideas would have remained summary if it weren’t for AI. It’s straightforward to invest, saying ‘that is my definition of kindness,’ which isn’t mathematically significant, however now with AI, it is virtually necessary as a result of if we wish to make AI type, we’ve got to inform it within the language of arithmetic what kindness is, for instance,” Dr. Tanaka informed me final week on the sidelines of the Improve convention.  

Early on of their analysis, the PHI Lab acknowledged the significance of understanding the “black field” nature of AI and machine studying to develop new programs with improved power effectivity for computation. AI’s development within the final half decade, nevertheless, has evoked more and more necessary security and trustworthiness issues, which have thus grow to be important to {industry} functions and governance choices on AI adoption. 

Via the brand new analysis group, NTT Analysis will handle the similarities between organic and synthetic intelligences, thus hoping to unravel the complexities of AI mechanisms and constructing extra harmonious fusion of human-AI collaboration. 

Though novel in its integration of AI, this method will not be new. Physicists have sought to disclose the exact particulars of technological and human relationships for hundreds of years, from Galileo Galilei’s research on how objects transfer and his contribution to mechanics, to how the steam engine knowledgeable understandings of thermodynamics through the Industrial Revolution. Within the twenty first century, nevertheless, scientists are in search of to grasp how AI works when it comes to being educated, accumulating information and making choices in order that, sooner or later, extra cohesive, secure and reliable AI applied sciences will be designed. 

“AI is a neuronetwork, the best way it’s structured is similar to how a human mind works; neurons linked by synapses, that are all represented by numbers inside a pc. After which that’s the place we consider that there will be physics… Physics is about taking something from the universe, formulating mathematical hypotheses about their interior workings, and testing them,” stated Dr. Hanaka. 

The brand new group will proceed to collaborate with the Harvard College Middle for Mind Science (CBS), and plans to collaborate with Stanford College Affiliate Professor Suya Ganguli, with whom Dr. Tanaka has co-authored a number of papers. 

Nevertheless, Dr. Tanaka stresses {that a} natural-science and cross-industry method might be basic. In 2017, when he was a PhD candidate at Harvard, the researcher realized that he needed to do greater than conventional physics, and comply with within the footsteps of his predecessors, from Galilei to Newton and Einstein, to open up new conceptual worlds in physics. 

“Presently, AI is the one matter that I can discuss to everybody about. As a researcher, it’s nice as a result of everyone seems to be at all times as much as speaking about AI, and I additionally study from each dialog as a result of I notice how individuals see and use AI otherwise, even past educational contexts. I see NTT’s mission as being the catalyst to spark these conversations, no matter individuals’s backgrounds, as a result of we study from each interplay,” Dr. Tanaka concluded.

Keep away from Challenges when Planning for Wi-Fi-7


Former U.S. Secretary of State James Baker as soon as mentioned, “Correct preparation prevents poor efficiency.”

When contemplating upgrades to Wi-Fi 7, or 802.11be, enterprises have to maintain Baker’s phrases in thoughts and have a look at greater than generally touted options to make sure a clean deployment.

Wi-Fi 7 merchandise provide improved efficiency and effectivity over Wi-Fi 6, particularly in high-density environments frequent amongst enterprises. Wi-Fi 7 can higher handle simultaneous visitors from a number of customers and typically cut back the variety of entry factors (APs) wanted, simplifying community administration and upkeep.

The IEEE commonplace 802.11be works with a number of radio frequency bands, together with 2.4 GHz, 5 GHz and, most just lately, 6 GHz. It will possibly ship theoretical hyperlink speeds of as much as 40,000 Mbps, relying on the configuration and setting. Wi-Fi 7 vastly improves the standard and determination of video streaming, due to 16 spatial streams and a number of enter, a number of output (MIMO) expertise. Hybrid computerized repeat request (HARQ) allows a number of hyperlink adaptation and error correction to enhance information reliability. Wi-Fi 7 gadgets are additionally appropriate with their most up-to-date predecessor, Wi-Fi 6E.

Do APs Assist the 6 GHz Band?

For enterprises upgrading to Wi-Fi 7, it is necessary to find out whether or not the AP thought of helps the brand new 6 GHz band. Assist of the 6 GHz band is implied with a Wi-Fi 6E label; nevertheless, it’s not a requirement with Wi-Fi 7.

Associated:Ideas for Enterprises Evaluating Wi-Fi 7

U.S.-based multinationals want remember that some nations, corresponding to India and China, don’t enable Wi-Fi transmissions within the 6 GHz band. Enterprises in these nations can buy Wi-Fi 7 APs that transmit and obtain solely within the legacy 2.4 GHz and 5 GHz bands. Nonetheless, enterprises in nations that do enable 6 GHz transmission ought to take benefit, in line with Siân Morgan, analysis director at Dell’Oro Group, a telecom market analysis agency.

“Enterprises in nations that help half or all of the 6 GHz band — for instance, all nations in North America, Europe in addition to Brazil, Columbia and Argentina in South America — ought to make sure that the AP mannequin they’re contemplating has a radio that may function in 6 GHz,” Morgan mentioned.

If an AP helps 6 GHz, newer gadgets will join utilizing the 6 GHz band. This helps cut back interference within the 2.4 GHz and 5 GHz bands, enhancing the general Wi-Fi expertise.

For an entire checklist of nations that help the 6 GHz band, Morgan steered readers seek the advice of the Wi-Fi Alliance web site.

Quick Knowledge Speeds and Energy Wants Have an effect on Efficiency

With Wi-Fi 7’s increased information charges and energy necessities, current community switches may trigger bottlenecks in enterprise wi-fi LANs, on account of their lack of help for hyperlinks greater than 1 Gbps. This could restrict total efficiency. The Wi-Fi 7 APs available on the market as we speak help 2.5 Gbps hyperlinks — or increased — from the swap. As well as, APs may want extra energy to totally use the 6 GHz band, which might exceed the Energy over Ethernet capability of current switches. Morgan mentioned enterprises ought to take into account potential workarounds.

“Enterprises ought to look rigorously on the end-to-end community and take into account the necessity to renew cabling and swap capability,” Morgan mentioned. “If there’s merely not the price range to improve Wi-Fi APs and switches on the identical time, enterprises could take into account buying Wi-Fi 7 APs that may be configured to function at decrease energy, forgoing the usage of 6 GHz briefly.”

As soon as enterprises improve the switching and cabling, they’ll reconfigure the APs to function at full capability.

Safety Strategies

Enterprises presently utilizing Wi-Fi 5 with WPA2 safety will profit from the improved safety of the WPA3 safety certification, which has been mandated since Wi-Fi 6. WPA3 makes use of a brand new authentication methodology and cryptographic handshake to bolster safety.

It is also important for enterprises to remain present with the most recent supported variations of Wi-Fi from their distributors to make sure they’ve entry to the most recent safety patches and options.

Time to Discover Campus Community as a Service

A Wi-Fi 7 improve is likely to be an acceptable time for community groups to simplify wi-fi LAN (WLAN) operations. Many distributors provide AI-fueled analytics to simplify set up, community configuration and troubleshooting. Enterprises can even take into account campus community as a service (CNaaS), Morgan mentioned.

“There may be additionally an possibility for enterprises to remove the upfront price and ongoing upkeep effort of their WLAN by transferring to a CNaaS providing,” Morgan mentioned.

With this rising sort of service, both the gear vendor or the managed service supplier (MSP) delivers the community for a recurring price, paid month-to-month, for example. With CNaaS, the seller or MSP additionally takes care of the set up, monitoring and downside decision, Morgan added. A few of these affords embrace a service-level settlement, so the corporate can obtain service credit if the community efficiency dips beneath a specified stage.

Very Low Energy Machine Assist — TBD

On the finish of 2024, the FCC adopted guidelines to permit Very Low Energy gadgets to function within the 6 GHz band. This might open a brand new ecosystem of gadgets that function throughout quick distances however require excessive connection speeds, corresponding to AR/VR headsets or gadgets enabling in-car connectivity. However adoption stays to be seen, in line with Morgan.

“Entry to the brand new spectrum is attention-grabbing, however the success of Wi-Fi VLP will rely on ecosystem improvement — that’s, the variety of gadgets and APs which might be licensed and the penetration of those inside enterprises and households,” Morgan mentioned.
