Shape-Shifting Garments Made Possible by Smart Textiles

0

Invisibility cloaks are frequently spotlighted in science fiction, showcasing futuristic technology. While similar advancements in smart clothing aren’t ruled out in the near future, there are equally intriguing applications on the horizon. Besides aesthetic features like color-shifting, researchers are advancing a new wave of smart textiles capable of adapting their structure to regulate body temperature. A recent development comes from a team of specialists at MIT in the United States, unveiling a material with this remarkable capability.

Smart textiles that change according to environmental conditions

Many of us have likely experienced the dilemma of wearing too many or too few clothes when stepping out on the street. Perhaps the weather unexpectedly turned too hot, rendering a thick sweater uncomfortable. Conversely, a sudden chilly wind may have left us regretting the choice of a denim jacket instead of a warmer wool coat. MIT suggests a solution to these weather-related challenges is using liquid crystal elastomer (LCE) fibers, known as FibeRobo. These fibers can regulate body temperature, offering a promising solution to address such weather fluctuations.

What are their characteristics?

Smart textiles’ distinguishing feature is their ability to sense the environment and respond to stimuli, typically achieved through passive means or by utilizing external energy sources.

MIT’s fibers fall into the category of passive smart textiles. They autonomously contract in response to a drop in temperature, enhancing thermal insulation. As the ambient temperature increases, the fabric regains its original structure—all achieved without electricity.

An additional advantage of this smart fabric is its compatibility with other textiles, including electrically conductive fibers. This allows for electrical signals to contract or expand the fabric selectively. For instance, researchers envision sportswear garments like bras whose fabric contracts before a training session.

The key to this functionality lies in the unique characteristics of the liquid crystal, capable of flowing like a liquid or settling into periodic crystalline structures. Developers integrated these crystals into an elastomer network, mimicking a rubber band’s stretching and contracting properties.

In the presence of heat, the crystals disarrange and compress the elastomer network, causing the fabric to contract. The manufacturing process allows fine-tuning the thermal response to adapt to body temperature and desired levels of contraction or expansion.

Producing this innovative textile material posed challenges, but the research team successfully manufactured the LCE-based fibers using 3D printing and precision laser-cut parts. The process involves heating resins, generating yarns through nozzles, and subjecting them to ultraviolet radiation. Remarkably, this technique produces up to one kilometer of fiber in a single day.

MIT’s smart material does not require sensors, circuits, or electronic devices to deliver its advanced functionalities. Additionally, researchers anticipate relatively low production costs, and the fibers can seamlessly integrate into existing manufacturing systems without needing new machinery.

Main functions of smart textiles

Alongside sustainability, the textile industry grapples with a significant shift towards smart garments. It’s crucial to distinguish between wearables, like patches integrated into T-shirts, and smart fabrics—textile fibers intrinsic to the garment’s structure, manufactured akin to conventional fibers like wool or cotton. Laboratories are currently focusing on five fundamental functionalities, employing either passive or active technologies:

  • Sensors: These enable clothing to detect changes in temperature, light, heart rate, pressure, or humidity, among other factors.
  • Communication: Crucially, garments will transmit information collected by sensors, either wirelessly or through circuits.
  • Storage: Future clothing may store energy within its fibers for use by integrated computer systems.
  • Data processing: Smart wearables are expected to possess some computational signal processing capability.
  • Actuators: Certain fibers will convert energy into vibration, sound, or changes in structure, like MIT’s thermal fabrics.

IFPI praises Brazil court ruling in streaming fraud case as a major success for ‘Operation Authentica’ initiative

0

A São Paulo court has issued a ruling against Seguidores Marketing Digital, ordering the company to cease providing fake followers, likes, and streams on platforms like Spotify, YouTube, TikTok, and Instagram.

The IFPI, which represents the global recording industry, said the ruling marks the first under Operation Authentica, an initiative targeting the streaming fraud industry.

The São Paulo Public Attorney’s Office led the operation through its Consumer Protection Unit and Cyber Gaeco division, supported by industry groups APDIF and IFPI Latin America. Investigators have identified 38 local websites offering streaming fraud services.

Seguidores has been found liable for misleading advertising and consumer fraud while violating constitutional rights protections. The court has then ordered Seguidores to cease its fraudulent services, pay damages and suspend its domain names.

The company will face additional fines if it continues operations. Seguidores has filed an appeal challenging the ruling, the IFPI said.

“This is a clear warning to those profiting from manipulating the online music environment. Their actions mislead music fans and undermine legitimate artists.”

Victoria Oakley, IFPI

IFPI CEO Victoria Oakley said: “This is a clear warning to those profiting from manipulating the online music environment. Their actions mislead music fans and undermine legitimate artists.

“Today’s ruling sets a strong legal precedent, and we are grateful to the São Paulo Public Attorney’s Office for this successful operation. We will continue to work closely with authorities to tackle these fraudulent practices, and to help protect Brazil’s thriving music community.”

Paulo Rosa, President, Pro-Música Brasil, added: “The content of this ruling goes beyond the music streaming manipulation itself. It adds the defense of consumer rights to cases where artificial and inorganic means are used to boost content online.

“We applaud this decision and will continue to work closely with Brazilian authorities to protect the integrity of our legitimate music market.”

The ruling follows the launch of what Brazilian law enforcement described as the “largest-ever” operation to disrupt streaming fraud. The initiative, launched in April, targets JustAnotherPanel, a global organization that provides technical infrastructure to a large network of resellers that offer fake streams used in streaming manipulation.

“The content of this ruling goes beyond the music streaming manipulation itself. It adds the defense of consumer rights to cases where artificial and inorganic means are used to boost content online.”

Paulo Rosa, Pro-Música Brasil

At the time, the IFPI said Cyber Gaeco, the cybercrime unit of the prosecutor’s office in Sao Paulo, obtained a court order that blocked JustAnotherPanel in Brazil, and at least 43 local illegal services have been disrupted, and 1,131 resellers of streaming fraud services outside Brazil have been impacted.

The development marks the latest in the crackdown on streaming fraud in Brazil. In March, authorities in the country arrested and charged a man accused of uploading more than 400 fake tracks to Spotify, generating more than 28 million plays and earning the unnamed suspect roughly $65,000.

Authorities also alleged that the suspect had stolen 36 tracks from local composers through promotional WhatsApp groups.

Elsewhere in 2020, Brazilian authorities announced they had taken down 14 websites involved in streaming manipulation, and the following year, they announced they had shut down 10 streaming manipulation services, while another 20 stopped offering the services.

In another case in 2023, Brazilian law enforcement took down FileWarez, which IFPI described as the most popular illicit file-sharing site in the country, which at its peak counted 118,000 registered users.

In 2024, law enforcement’s Operation Redirect took down eight illegal online music services that were being used to distribute malware to users.

Authorities in Brazil have also been running an ongoing initiative called Operation 404, to take down copyright-infringing music services with the cooperation of trade groups like IFPI and Pro-Música. According to the Office of the US Trade Representative, as of September 2024, seven Operation 404 initiatives had been carried out, the most recent focusing on stream-ripping sites and apps in Brazil and Paraguay.

British fighter jet stranded in India poised for takeoff

0

A state-of-the-art British fighter jet that has been stuck at an Indian airport for more than five weeks is set to fly out on Tuesday.

The F-35B is due to be “pulled back from the hangar today and the departure is scheduled for Tuesday”, an airport spokesman told the BBC. “We do not have any technical details,” he added.

The F-35B landed on 14 June at Thiruvananthapuram airport in the southern state of Kerala where it was diverted after it ran into bad weather during a sortie in the Indian Ocean. It then developed a technical snag.

Its prolonged presence on Indian soil sparked curiosity and raised questions about how such a modern aircraft could remain stranded in a foreign country for so long.

After the plane, which was part of the fleet of the HMS Prince of Wales, was unable to return, engineers from the Royal Navy’s flagship carrier visited it to fix it.

But they were unable to repair it, and a fortnight back, the UK ministry of defence said they had deployed a team of 14 engineers “to Thiruvananthapuram airport to assess and repair the F-35B aircraft”.

The team came with specialist equipment necessary for the movement and repair process, a statement said. Videos from the time showed the F-35B being towed away to a hangar.

There had been speculation that if the technicians failed to repair the aircraft, it would have to be dismantled and carried out in a bigger cargo plane such as a C-17 Globemaster transport aircraft.

Over the past two weeks, the UK high commission in India and the defence authorities have responded to the BBC’s messages saying they would not share details of repairs.

But on Monday, an airport official told the BBC that “the aircraft is confirmed to be airworthy”.

It is scheduled to be pulled out of the hangar on Monday morning, he said, adding that the exact time of its departure is “yet to be communicated, which airport will be used for refuelling on the way to London or when the backup aircraft will arrive to transport the technicians and equipment back”.

F-35Bs are highly advanced stealth jets, built by Lockheed Martin, and are prized for their short take-off and vertical landing capability.

Images of the “lonely F-35B”, parked on the tarmac and soaked by the Kerala monsoon rains, made it a subject of jokes and memes with many suggesting that it did not want to leave the scenic state of Kerala, described as “God’s own country” in tourism brochures.

The case of the stranded $110m (£80m) jet was also raised in the House of Commons.

South Korea Rains Claim 18 Lives, Meteorological Agency Issues Heatwave Warning | Climate Crisis Update

0

Five-day deluge unleashed flash floods and landslides that killed 18 and left nine others missing, authorities say.

Torrential rains that lashed South Korea have killed at least 18 people and left nine others missing, authorities said, as the government lifted advisories for heavy rain and the meteorological agency warned of a return of heatwaves to southern parts of the country.

The toll on Monday came as South Korea’s military also announced dispatching thousands of troops to rain-ravaged areas to assist in recovery efforts.

The downpours began on July 16 and brought some of the heaviest hourly rainfall on record to some of South Korea’s central and southern provinces. The five-day deluge collapsed homes, triggered landslides and unleashed flash floods that swept away cars and campers.

At least 10 people were killed in the southern county of Sancheong, and four others remain missing there, according to the Ministry of the Interior and Safety.

Another person was killed when their house collapsed in the town of Gapyeong, northeast of the capital, Seoul, while a man who had been camping near a stream there was found dead after being swept away by rapid currents.

The man’s wife and teenage son remain missing, the South Korean JoongAng Daily reported. Two others, including a man in his 70s who had been buried in a landslide, were listed as missing in the same town.

The rains also forced some 14,166 people to evacuate their homes in 15 cities and provinces, and caused “extensive property damage”, the Yonhap news agency reported.

The agency said 1,999 cases of damage had been recorded at public facilities, and 2,238 cases were recorded at private homes and buildings.

South Korea’s military said it has dispatched some 2,500 personnel to the southwestern city of Gwangju as well as the South Chungcheong and South Gyeongsang provinces to assist in the recovery efforts.

The troops will be overhauling homes and stores affected by the rains, it said.

Hannah June Kim, an associate professor in the Graduate School of International Studies at Sogang University in Seoul, told Al Jazeera that “a lot of people were taken off guard” because monsoonal rains came later than expected this year.

“The expectation was that monsoons would not be appearing during this summer,” she said. “So, when this heavy rain started to fall this past week, a lot of local areas were unprepared.”

“We are seeing the heavy effects of climate change and how it’s affecting different areas,” she added.

South Korea’s Meteorological Administration (KMA) forecast more rainfall in the southern regions on Monday but said that a heatwave would follow. According to the JoongAng Daily, heatwave advisories and warnings have already been issued for parts of South Jeolla, the east coast of Gangwon and Jeju Island.

“From July 24 onward, morning lows will remain between 23 and 26 degrees Celsius [73.4F to 78.8F], and daytime highs will range from 30 to 35 degrees Celsius [86F to 95F], higher than the seasonal averages of 22 to 25 degrees Celsius [71.6F to 77F] in the morning and 29 to 33 degrees Celsius [84.2F to 91.4F] during the day,” it reported, citing the KMA.

Scientists say climate change has made extreme weather events more frequent and intense around the world.

In 2022, South Korea endured record-breaking rains and flooding, which killed at least 11 people.

They included three people who died trapped in a Seoul basement apartment of the kind that became internationally known because of the Oscar-winning Korean film Parasite.

The government said at the time that the rainfall was the heaviest since records began, blaming climate change for the extreme weather.

BYD’s dominance in China’s car market is starting to waver

0

Life at the top is proving complex for China’s leading automaker, and there are fresh challenges on the horizon.

BYD Co.’s monthly sales have stagnated of late and with the summer months being a traditionally slower time for consumer purchases, that trajectory isn’t expected to reverse any time soon. 

Discounting is also now being looked sternly upon by Beijing, with China last week pledging to rein in “irrational competition” in the electric vehicle sector, reflecting authorities’ wish to tackle the deflationary price wars that are threatening economic and industrial growth.

Some of BYD’s international forays are also proving more challenging than expected, raising the question, is China’s No. 1 automaker on shaky ground?

The Shenzhen-based behemoth currently looks like it will undershoot its annual sales target for 2025, in what would be a rare miss after a multi-year bull run. The number of electric and hybrid vehicles BYD needs to sell each month through December has hit 560,000 units, in excess of levels it could hope to achieve typically in a single month. The most vehicles BYD has ever sold in a month was just shy of 515,000, in December last year.

Analysts are now doubting whether BYD can hit 5.5 million units in 2025. Consensus estimates continue to be downgraded.

Deutsche Bank AG earlier this month said it now expects 5 million in wholesales, or deliveries to dealers, for this year, comprised of 4 million domestic units and 1 million overseas, while Morgan Stanley last month lowered its projection to 5.3 million, pointing to a smaller number of new models. Bloomberg Intelligence’s Joanne Chen says BYD will need to sacrifice some profit and maintain its hefty discounting in the second half if it wants to stay on track.

“Regulatory scrutiny will temper direct cuts to vehicle sticker prices but competition isn’t going away and retail promotions are still needed to sustain sales momentum,” she said. “New model roll outs and steady tech upgrade are also crucial.”

Bing Yuan, a fund manager at Edmond de Rothschild Asset Management, said many market watchers now realistically expect sales of around 5 million. “My sense is that is the consensus,” she said.

Stripping out overseas and commercial sales, BYD’s core car deliveries in China are shrinking. In June, they slipped 8% year-on-year as vehicles from brands like Zhejiang Geely Holding Group Co., Xpeng Inc. and Xiaomi Corp. won over buyers. HSBC Holdings Plc data show that Geely was the largest gainer of market share in the first half, while BYD was among the biggest losers.

Overseas sales are faring better and those are looking on target to reach BYD’s forecast of 800,000. Indeed, BYD is already almost 60% of the way there. But while higher margin international sales will help BYD offset aggressive domestic discounting, some foreign markets are presenting new difficulties.

BYD has grand plans for Saudi Arabia, for example, hoping to triple its footprint after Tesla Inc. entered the country. But EVs account for just over 1% of total car sales in the kingdom, with high costs, sparse charging infrastructure and extreme temperatures challenging EV adoption.

India, a potentially huge market, has meanwhile consistently blocked BYD’s efforts to expand and despite rapid growth from a low base in Europe, there are substantial tariff headwinds and increasing competition from legacy automakers that already have consumers’ trust, not to mention more extensive after-sales networks.

At home, regulatory scrutiny has also intensified around BYD as it continues to be at the fore of an EV price war. In late May, it slashed prices by as much as 34%, triggering renewed sector-wide discounts. Its moves were later discouraged in a veiled warning by the Chinese Communist Party’s mouthpiece the People’s Daily, which slammed the “rat-race competition.”

Whether Beijing can actually stop price discounting by a privately held company is a point of debate.

Tianlei Huang, a China program coordinator at the Peterson Institute for International Economics, said authorities may resort to administrative tools such as price reviews or cost investigations to establish a de facto price floor, or coordinate a concerted capacity reduction among leading EV makers, although he acknowledged those measures won’t be easy.

Regardless, BYD must be careful. As the company gears up to release first-half results later next month and July sales data within weeks, analysts will have their spreadsheets at the ready, waiting to see whether those 2025 targets look even further in the distance.

Notorious Ecuadorian drug lord ‘Fito’ extradited to United States

0

The powerful Ecuadorean gang leader Adolfo Macías Villamar has been extradited to the United States to face charges of drug and arms trafficking.

Known as “Fito”, he was recaptured in June, almost a year after he escaped from a high-security prison where he was serving a 34-year sentence for a series of crimes.

He will appear in a US federal court on Monday, where he will plead not guilty to international charges of drug and weapons trafficking, his lawyer told Reuters.

Macías was leader of Los Choneros gang, which is linked to powerful criminal organisations from Mexico and the Balkans. He is also suspected of having ordered the assassination of presidential candidate Fernando Villavicencio in 2023.

Los Choneros is blamed for Ecuador’s transformation from a tourist haven to a country with one of the highest murder rates in the region.

More than 70% of all cocaine produced in the world currently passes through Ecuador’s ports. The country is located between the world’s two top cocaine exporters, Colombia and Peru.

In June, police tracked Macías down to what they described as an underground bunker below a luxury home in the city of Manta. He was taken to La Roca, a maximum security prison. At the time, Ecuador’s President Daniel Noboa praised the security forces for capturing him and said that he would be extradited to the US.

The country’s prison authority said he was taken out of prison in Ecuador earlier on Sunday to be handed over to US authorities.

“Mr Macías and I will appear tomorrow before the Brooklyn federal court … where he will plead not guilty,” his lawyer, Alexei Schacht, told Reuters. “After, he will be held in a to-be-determined prison.”

Ecuadoreans voted in favor of allowing the extradition of citizens in a referendum called by President Noboa, who vowed to crack down on rising crime.

In March this year, Noboa told the BBC he wants US, European and Brazilian armies to join his “war” against criminal gangs.
