Un grupo de investigadores estonios propone transformar la tecnología descartada en herramientas útiles para el procesamiento de datos (Universidad de Tartu/Kadri-Ann Kivastik)

Cada año, se producen más de 1.200 millones de teléfonos inteligentes en todo el mundo, una cifra que refleja tanto el avance tecnológico como el desafío ambiental que implica la rápida obsolescencia de estos dispositivos. En este contexto, un grupo de investigadores de la Universidad de Tartu, en Estonia, desarrolló un método para convertir teléfonos viejos en pequeños centros de datos. Esta propuesta, según informó la universidad, busca reducir los desechos electrónicos y fomentar prácticas de sostenibilidad tecnológica.

El coste estimado para adaptar cada dispositivo es de casi 10 dólares, lo que convierte esta solución en una alternativa económica para el reaprovechamiento de tecnología descartada.

La fabricación masiva de dispositivos electrónicos, en especial teléfonos inteligentes, conlleva un alto consumo de energía y recursos naturales. Además, sus procesos de producción y distribución generan importantes emisiones de CO2.

De acuerdo con la Universidad de Tartu, los usuarios cambian sus teléfonos cada dos o tres años, incluso cuando estos aún funcionan correctamente. Aunque algunos se reciclan, muchos terminan en vertederos, agravando la crisis del desperdicio tecnológico.

El avance constante de la tecnología deja obsoletos a los modelos anteriores en poco tiempo, dificultando un cambio de hábitos de consumo. Si bien modificar el comportamiento de los usuarios sería una solución más sostenible, los investigadores reconocen que esta transformación cultural es compleja. Por eso, encontrar alternativas que prolonguen la vida útil de los dispositivos resulta clave para disminuir su impacto ambiental.

Ante este escenario, el equipo liderado por Huber Flores, Ulrich Norbisrath y Zhigang Yin, del Instituto de Ciencias de la Computación de la Universidad de Tartu, junto a Perseverance Ngoy, del Instituto de Tecnología, y colaboradores internacionales, propone reutilizar teléfonos antiguos como centros de datos compactos. Según detallaron, estos dispositivos pueden adaptarse para procesar y almacenar información de forma eficiente.

El proceso es de bajo costo: casi 10 dólares por teléfono, incluyendo los materiales necesarios. Esta accesibilidad permite su implementación en distintos entornos. Flores, profesor asociado de Computación Pervasiva, explicó: “La innovación a menudo comienza no con algo nuevo, sino con una nueva forma de pensar sobre lo antiguo”.

Las posibles aplicaciones de estos centros de datos reciclados son diversas. En zonas urbanas, podrían instalarse en paradas de colectivos para recolectar datos sobre el flujo de pasajeros en tiempo real, lo que facilitaría ajustar rutas y frecuencias del transporte público. De acuerdo con la universidad, este tipo de uso demuestra cómo la tecnología reutilizada puede integrarse en infraestructuras ya existentes para mejorar la eficiencia de los servicios.

Los prototipos también fueron sometidos a pruebas en condiciones extremas. En un experimento destacado, el sistema fue utilizado bajo el agua para monitorear especies marinas. Tradicionalmente, esta tarea requiere la intervención de buzos que registran videos para su análisis posterior.

En cambio, el prototipo automatizó el proceso, permitiendo contabilizar especies directamente en el entorno submarino. Este resultado evidenció que los teléfonos reciclados pueden funcionar en escenarios exigentes y ofrecer soluciones innovadoras para la investigación científica y ambiental.

El desarrollo del prototipo incluyó modificaciones técnicas enfocadas en la seguridad y la sustentabilidad. En primer lugar, se retiraron las baterías de los teléfonos, reemplazándolas por fuentes de alimentación externas, lo que evitó posibles fugas químicas asociadas al deterioro de las baterías.

Luego, los dispositivos se ensamblaron en grupos de cuatro, utilizando carcasas impresas en 3D. Esta configuración permitió crear una unidad funcional y compacta, lista para su reutilización. La Universidad de Tartu subrayó que este método favorece el uso de componentes ya existentes y reduce la necesidad de fabricar nuevos equipos, en línea con prácticas de economía circular.

El equipo de la universidad resalta la necesidad de replantear el destino de los dispositivos obsoletos. Norbisrath, profesor asociado de Ingeniería de Software, por su parte remarcó: “La sostenibilidad no se trata solo de preservar el futuro, se trata de reinventar el presente, donde los dispositivos de ayer se convierten en las oportunidades del mañana”. Reflejando una visión orientada a convertir los desafíos medioambientales en soluciones tecnológicas responsables.

Los resultados del proyecto demuestran que los teléfonos inteligentes antiguos pueden tener un nuevo propósito como infraestructura digital eficiente.

Con recursos mínimos y un enfoque creativo, estos dispositivos cobran una segunda vida útil, reduciendo el desperdicio electrónico y aportando valor en múltiples áreas. Como concluyó Norbisrath, reinventar el presente mediante la reutilización tecnológica es un paso fundamental hacia un futuro más sostenible.

Un hombre acosó a la presidenta de México, Claudia Sheinbaum, en plena recorrida en el DF

Published

on



La presidenta de México, Claudia Sheinbaum, fue acosada este miércoles mientras recorría las calles del centro histórico de la Ciudad de México por un hombre que no fue identificado. El momento quedó registrado en un video, donde se ve que su escolta de seguridad no la estaba acompañando en ese momento.

Según indicaron medios locales, todo ocurrió durante el traslado de la mandataria a la Secretaría de Educación Pública (SEP) en el Centro Histórico de la Ciudad de México. Sheinbaum frenó en la calle para dialogar con algunos vecinos frente a las cámaras de televisión cuando un hombre se le acercó por detrás y le pasó un brazo sobre los hombros.

Mientras lo hacía, el hombre intentó darle un beso, pero el movimiento de la presidenta mexicana se lo impidió. Sin embargo, el sujeto continuó con sus actos y comenzó a recorrer con sus manos el cuerpo de la mandataria.

«Ey, ey, ey, ey», se escucha quejarse a Sheinbaum mientras se saca al hombre de encima. En ese momento, una de las personas que estaba grabando con un celular -y que presuntamente sería el titular de la Dirección General de Ayudantía, Juan José Ramírez Mendoza-, se mete y aparta al hombre, que insiste en su intento de abrazarla.

Marcando distancia, la mandataria le responde «nos tomamos la foto, no te preocupes». El hombre, en aparente estado de ebriedad, murmura algunas palabras que no se llegan a entender. El video concluye en ese momento y, según se indicó, esta persona no fue identificada.

Horas más tarde, se difundió en redes otro video que muestra el momento en el que, luego del ataque, la presidenta mexicana se toma igualmente una foto con su agresor. Quien sostiene el celular a modo de cámara parece ser justamente uno de los hombres que la habían defendido anteriormente.

Según indicó la prensa mexicana, el ataque ocurrió sobre la calle República de Argentina, en el Centro Histórico de la Ciudad de México. Hasta el momento, las autoridades mexicanas no se expresaron al respecto.

Más temprano, la presidenta mexicana había presentado un plan de refuerzo en la seguridad

Claudia Sheinbaum anunció más temprano, este mismo martes, una “estrategia integral” para el estado de Michoacán, en el oeste de México, en donde en los últimos días se registraron protestas que incluyeron la toma del palacio de Gobierno de Urupán, luego del asesinato del alcalde local Carlos Manzo Rodríguez, ocurrido el domingo pasado.

Fue en ese contexto que la mandataria presentó en su conferencia matutina el “Plan Michoacán por la Paz y la Justicia” con el que, según explicó, se impulsará un “reforzamiento de seguridad” bajo un “esquema integral” que incluirá la atención de las causas de la violencia.

Durante su exposición, Sheinbaum informó que se enviarán nuevos contingentes de la Guardia Nacional y agentes de la Secretaría de Seguridad federal para apoyar a la policía de Michoacán, aunque no dio cifras.

Según cifras oficiales, en septiembre Michoacán había ocupado el séptimo lugar en el número de homicidios de México, al acumular 1.024 casos en los primeros nueve meses del año.

Las autoridades estatales aseguran que en el primer semestre de este año disminuyeron 17% los homicidios en Michoacán, en comparación con el mismo período del 2024. Sin embargo, los recientes asesinatos de los alcaldes de Tepalcatepec y Tacámbaro, Martha Laura Mendoza y Salvador Bastidas; del periodista Mauricio Cruz Solís y del líder de los productores de limón de Apatzingán, Bernardo Bravo, continúan despertando preocupación.

Entre 2022 y 2024 también habían sido baleados otros cuatro alcaldes en Michoacán: Yolanda Sánchez en el municipio Cotija; Guillermo Torres en la localidad de Churumuco; César Valencia en el municipio Aguililla, y Enrique Velázquez en el municipio Contepec.

«Following the completion of the identification process by the National Institute of Forensic Medicine, in cooperation with the Israel Police and the Military Rabbinate, IDF representatives informed the family that Itay had been returned for burial,» the military said.

Chen served as a combat soldier in the 77th Battalion of the 7th Armored Brigade. He was killed on the morning of October 7, 2023, while fighting near Kibbutz Nahal Oz—one of the hardest-hit communities in Hamas’s brutal attack. Chen’s tank was struck during the battle, and his body was taken into Gaza. His death was officially confirmed on March 10, 2024.

Itay was the middle of three brothers. He grew up in Netanya, a city in central Israel, studied in an advanced academic program, and was known for his warmth, humor, and dedication. He loved basketball, hiking, and rock climbing, and before joining the army worked as a camp counselor. Even after sustaining an injury at camp, he insisted on finishing the summer to set an example for the kids he led. Later he enlisted as an armored-corps soldier, driven by a deep sense of duty to protect others. He leaves behind his parents, Ruby and Hagit, and his brothers Roi and Alon.

Over the past year, his parents led an unrelenting campaign to bring their son home. They met with senior officials in Israel and Washington, including President Trump, advocating for the return of all hostages and the remains of the fallen.

Iran hackers taunted ‘Mr. Mustache’ John Bolton about stolen files that were allegedly classified

Published

NEWYou can now listen to Fox News articles!

Iranian hackers taunted former National Security Adviser John Bolton about files allegedly obtained from his email account that they said were classified, wishing «good luck» to «Mr. Mustache» as they threatened to leak the materials, an unsealed search warrant affidavit reviewed by Fox News Digital revealed.

Bolton pleaded not guilty in October to eight counts of transmission of national defense information and ten counts of retention of national defense information. He had been indicted with 18 counts related to the improper handling of classified materials. 

It was July 2021 when Bolton’s assistant contacted the FBI via email to alert them that Iran had obtained access to Bolton’s email account. Bolton’s team had notified the FBI that they would be deleting Bolton’s emails so that the hackers could not obtain any additional sensitive information. 

JOHN BOLTON PLEADS NOT GUILTY TO CHARGES OF SHARING CLASSIFIED INFORMATION

Weeks later, Bolton’s assistant contacted the FBI again to say that he had received threatening emails that were believed to be related to the hack of Bolton’s AOL account.

«The e-mail, the subject of which was ‘Re:New PW,’ as forwarded to the FBI, stated: ‘I do not think you would be interested in the FBI being aware of the leaked content of John’s email (some of which have been attached), especially after the recent acquittal. This could be the biggest scandal since Hillary’s emails were leaked, but this time on the GOP side! Contact me before it’s too late,’» according to the warrant.

In August 2021, Bolton’s assistant flagged another email from the same account that threatened to leak portions of Bolton’s manuscript found in his email.

«OK John…as you want (apparently), we’ll disseminate the expurgated sections of your book by reference to your leaked email,» the email said. «Good luck Mr. Mustache!»

The affidavit in support of the search warrant from a raid on Bolton’s home in September was unsealed and obtained by Fox News Digital.

The affidavit supporting the search warrant revealed additional details surrounding the case against Bolton.

JOHN BOLTON’S HOME AND OFFICE RAIDED BY FEDERAL AGENTS

‘CLASSIFIED INFORMATION’

According to the unsealed warrant, staff from the White House National Security Council visited Bolton’s home Sept. 10, 2019, to retrieve classified information and any government property following his termination as national security advisor.

The government had created a sensitive compartmented information facility, also known as a SCIF, in Bolton’s home Sept. 17, 2018. That SCIF was decertified Oct. 16, 2019, according to the warrant.

«Based on my education, training and experience, I know that the installation of a SCIF within the TARGET RESIDENCE indicated that Bolton anticipated storing classified materials within the TARGET RESIDENCE during his tenure as APNSA,» the affidavit states. «Once he was no longer APNSA, effective Sept. 10, 2019, his need-to-know expired, and any authorization for having access to the classified documents in the TARGET RESIDENCE was subsequently revoked.»

It was December 2019 when Bolton submitted a draft of his manuscript of «The Room Where It Happened,» his memoir, to Ellen Knight, the National Security Council senior director for records, access and information security management.

Knight acknowledged receipt of the manuscript, according to the warrant, and notified Bolton that «based on a preliminary review, the manuscript appeared to contain significant amounts of classified information, to include information classified at the TOP SECRET level.»

Knight suggested Bolton modify and resubmit the manuscript due to the «large volume of classified information contained» in it.

«Knight indicated that, in all her experience, she had never seen that level of classified material and specificity of detail in a manuscript submitted for review,» the affidavit read. «There were quotes from foreign leaders from negotiations with the President and details of foreign military actions which had not yet been publicly acknowledged by the foreign governments.»

«Based on her experience in reviewing manuscripts for pre-publication review and the level of detail contained in Bolton’s submission, Knight surmised that Bolton either had an incredible memory or had to be writing from notes he would have taken as APNSA. Knight explained that any such notes were likely classified, fall under the PRA, and should have been turned over by Bolton at the conclusion of his government service,» the affidavit read. 

But on Dec. 13, 2019, Bolton’s team confirmed that he had cleared classified documents and did not possess any additional classified documents at his home.

EX-NATIONAL SECURITY ADVISOR JOHN BOLTON INDICTED WITH IMPROPER HANDLING OF CLASSIFIED DOCUMENTS

The affidavit, though, revealed that in February 2020, Bolton’s assistant wrote an email to the National Security Council to notify them that Bolton was reinstalling a SCIF in his home and needed the contact information for someone at the National Security Council who could accredit the SCIF. That was unusual, according to the warrant, given Bolton was no longer an employee of the U.S. government. 

The National Security Council director of security responded the same day, telling Bolton and his team that installing an accredited SCIF in his home was «not a viable option.» 

It was more than a year later that Bolton’s AOL email account was hacked by a foreign entity, believed to be Iran.

Meanwhile, while Bolton attempted, and failed, to get a second SCIF accredited in his home, Bolton continued to refer to «the archives» in emails to himself and to two other individuals, whose identities remain redacted.

The warrant states that Bolton would designate «certain information» for «the archive,» which the warrant states is likely a physical space within his home.

‘POLITICAL REASONS’ 

The probe into Bolton’s alleged retention of classified documents was first launched years ago but later shut down by the Biden administration «for political reasons,» according to a senior U.S. official.

DEMOCRATS OPPOSED JOHN BOLTON FOR YEARS — UNTIL THEY SOUGHT HIM AS AN ALLY AGAINST TRUMP

The Justice Department under Trump’s first administration argued that Bolton’s 2020 memoir contained classified material and sought to block its publication. A federal judge ultimately allowed the book to be published.

Justice Department lawyers argued the book contained classified national security information covering areas like U.S. intelligence sources and methods, foreign policy deliberations and conversations with foreign leaders.

In June 2021, the Biden Justice Department abandoned both a criminal inquiry and civil lawsuit against Bolton over the memoir, ending the legal battle at that time.

Bolton’s attorney said at the time that a senior career official in charge of the National Security Council’s pre-publication review process conducted a four-month review of the book and, after requiring a number of revisions, concluded that it contained no classified information.

The book contained a damning account of the Trump White House, alleging that Trump once «pleaded» with Chinese President Xi Jinping to aid his re-election campaign, among other missteps.

Trump ousted Bolton from his first administration in 2019 because the pair «disagreed strongly» on policy. 

Bolton has both praised and criticized Trump since leaving his first administration.

He criticized Trump’s handling of classified documents, which led to an FBI raid on the former president’s Mar-a-Lago home in 2022 and a subsequent federal indictment, but insisted that «the legal process play out.»

BOLTON MAY BE IN HOT WATER AS FBI INVESTIGATION EXPANDS BEYOND CONTROVERSIAL BOOK

Trump initially was indicted on 37 felony counts, later expanded to 40, but the case was ultimately dismissed in July 2024.

In 2022, Bolton said Trump lacked the competence and character to be president.

However, Bolton strongly backed Trump’s military strike on Iran’s nuclear facilities in June, calling it «a decisive action,» «the right thing to do,» and praising its potential to generate «huge change in the Middle East.»

Trump, meanwhile, often has criticized Bolton for pushing U.S. involvement in wars in the Middle East. Bolton served as U.S. ambassador to the United Nations under President George W. Bush from August 2005 to December 2006.

Trump revoked Bolton’s Secret Service detail Jan. 21, the day after Trump’s inauguration as the 47th president, and Bolton said the move showed that Trump was coming after him.

«I think it is a retribution presidency,» Bolton told ABC earlier in 2025, responding to Trump’s move to revoke his security clearance.

Bolton has faced threats from Iran going back years, including an alleged plot to assassinate him in 2021 and the Department of Justice subsequently charging a member of Iran’s Islamic Revolutionary Guard Corps for the plot in 2022.

The Iranian threats against Bolton were likely sparked by the January 2020 U.S. strike that killed Qassem Soleimani, the head of Iran’s Quds Force, the Department of Justice reported in 2022. 

Bolton, in October, pleaded not guilty to 18 counts. 

U.S. Magistrate Judge Timothy Sullivan explained the charges to Bolton and asked if he understood them and the potential penalties of up to ten years per count and a maximum fine of $250,000 per count.

«I do your honor,» Bolton said during his arraignment at the federal courthouse in Greenbelt, Maryland. 

«From on or about April 9, 2018, through at least on or about August 22, 2025, BOLTON abused his position as National Security Advisor by sharing more than a thousand pages of information about his day-to-day activities as the National Security Advisor — including information relating to the national defense which was classified up to the TOP SECRET/SCI level — with two unauthorized individuals, namely Individuals 1 and 2,» the indictment reads. «BOLTON also unlawfully retained documents, writings, and notes relating to the national defense, including information classified up to the TOP SECRET/SCI level, in his home in Montgomery County, Maryland.»

The documents Bolton allegedly transmitted were sent to two individuals unauthorized to view classified documents, the indictment said.

Those documents, according to the indictment, revealed intelligence about future attacks by an adversarial group in another country, a liaison partner sharing sensitive information with the U.S. intelligence community, intelligence that a foreign adversary was planning a missile launch in the future and a covert action in a foreign country that was related to sensitive intergovernmental actions, among other information.
