Un tiburón dormilón rompe récords de supervivencia polar en las aguas de la Antártida

En una imagen capturada por una cámara sumergida a 500 metros de profundidad, científicos documentaron la presencia de un tiburón “dormilón” en aguas antárticas, un lugar donde hasta hace poco se creía poco habitual hallar a estos grandes depredadores.
La escena se desarrolló cerca de las islas Shetland del Sur, en un entorno donde las temperaturas del agua apenas superan el punto de congelación. El equipo del Centro de Investigación Oceánica Profunda Minderoo-UWA detectó a este tiburón gracias a una cámara instalada para monitorear la biodiversidad marina. Alan Jamieson, profesor de la Universidad de Australia Occidental y director del centro, recordó el asombro del grupo: “Todos nos quedamos perplejos, pensando: ‘No creo que haya tiburones en la Antártida’”, explicó a National Geographic.
Hasta ese momento, los registros de tiburones en la región se limitaban a aguas del Ártico y el Pacífico Norte, pero nunca tan al sur. El ejemplar, de entre dos y tres metros de longitud, pertenece al grupo de los tiburones dormilones, conocidos por su metabolismo extremadamente lento y su capacidad para vivir en ambientes hostiles.
La capacidad de los tiburones dormilones para soportar condiciones extremas se debe a una serie de adaptaciones únicas. Estos animales crecen menos de un centímetro al año y rara vez superan los cuatro kilómetros por hora de velocidad. Su bajo consumo energético les permite sobrevivir en entornos fríos y con escasez de alimento. Ese metabolismo reducido tiene ventajas claras. Al consumir muy poca energía, estos tiburones pueden sobrevivir en entornos donde el alimento es escaso y las temperaturas son extremadamente bajas.
La ciencia ha descubierto que sus tejidos contienen altas concentraciones de urea y N-óxido de trimetilamina (TMAO). La urea ayuda a mantener el equilibrio osmótico con el agua marina, aunque puede desestabilizar las proteínas del organismo. En ese punto, el TMAO actúa como estabilizador y permite que las proteínas funcionen a temperaturas cercanas al punto de congelación. “Aunque todos los tiburones tienen TMAO en su organismo, los tiburones dormilones tienen mucho más que la mayoría”, explicó el investigador Dave Ebert.

Otro aspecto sorprendente es la longevidad de estos animales. Estudios genéticos recientes han identificado duplicaciones en genes relacionados con la reparación del ADN y la protección contra el estrés oxidativo, un mecanismo que podría explicar por qué algunos tiburones de Groenlandia —parientes del ejemplar hallado— viven más de 400 años. Como la mayoría de los tiburones dormilones, este individuo puede haber estado vivo durante la era de Bellingshausen y James Clark Ross en el siglo XIX.
La cámara que permitió el hallazgo operaba en una zona donde una corriente de agua relativamente cálida fluye sobre el fondo marino. En este canal, la temperatura llegó a 1,27℃, lo que podría haber facilitado la presencia del tiburón en aguas tan australes.

El responsable de la investigación, Alan Jamieson, no oculta su incertidumbre: “Hay diferentes tipos de rareza en el mundo, y este tipo es absolutamente astronómico”, expresó. El propio Jamieson confesó que, en 25 años de carrera, solo había visto cuatro tiburones dormilones y nunca en la Antártida.
El hallazgo plantea interrogantes sobre la presencia de una posible población estable en el área. “Lo difícil es saber cuántos tiburones viven en aguas antárticas”, señaló Jamieson. Los científicos creen que la cámara pudo captar al tiburón porque se encontraba en una zona de agua ligeramente más cálida, lo que sugiere la existencia de corredores que permiten a estos animales explorar regiones más australes.
De momento, no existen datos suficientes para determinar si se trata de una aparición aislada o del indicio de una comunidad poco conocida. Como concluyó el propio Jamieson: “El descubrimiento de un tiburón dormilón en aguas antárticas sugiere que realmente no hay ningún lugar en el océano donde los tiburones no puedan sobrevivir”.

Hugo Llorens: «Si la guerra se extiende, Trump y los republicanos pagarán un precio muy duro»

Las diferencias entre Irán, Irak y Afganistán
Creo que cuando uno está tratando de analizar al presidente Trump, uno tiene que esperar lo inesperado
A mí me parece que no va a ser fácil para Trump buscar eliminar el programa nuclear
Esperar lo inesperado
El concepto de una guerra, de un conflicto muy extendido con Irán, no es viable políticamente para él, particularmente en un año donde tenemos elecciones
Tendremos que ver cuál es la capacidad de los bombardeos de Estados Unidos e Israel para degradarles esa capacidad. Esto lo vamos a ver en los próximos días
Hezbollah está muy debilitado
Estados Unidos tiene ciertas limitaciones (…) tienen capacidad de mantener estas operaciones por dos semanas.

Iran proxies wage war on Israel, threaten US interests as Iraq slammed for not disarming them

NEWYou can now listen to Fox News articles!
FIRST ON FOX: The Israeli military spokesman confirmed to Fox News Digital this week that multiple unmanned aerial vehicles, UAVs, have been launched into Israel from Iraqi territory since the start of the conflict with Iran to eradicate the Islamic Republic of Iran’s illicit nuclear weapons facilities, missile systems and terrorism infrastructure.
Lt. Col. Nadav Shoshani, the Israeli military spokesman, said that the army has had a «near complete success» rate in stopping Iranian drones from hitting Israeli targets.
The drones fired from Iraq are presumed to come from the Iranian regime-controlled Popular Mobilization Forces, or PMF. An umbrella organization of Shiite terrorists, that attacked Israel with drones in 2024 during Israel’s war against the Tehran-backed Hamas movement.

An Iraqi Kurdish official told Fox News Digital, «Iraq has become a vessel for the Iranians. Is it so hard to see? I don’t see a distinction between the PMF and the state. They’re paid by the state, hold sovereign portfolios in this cabinet, go on foreign travel and now they’ve entered the federal legislature.»
The official continued: «In the last two decades, Iran has systemically taken over the state, weaponizing what were supposed to be institutions into tools to protect the Shia regime in Baghdad and punish any threat to it, including the Kurdistan Regional Government (KRG). Through Baghdad and state institutions, it has economically strangled the Kurdistan Region, torn strips from our autonomy and exposed us to more attacks.»
An attack was reported on the country’s shrinking Christian community. The Chaldean Archbishop Bashar Warda of Erbil, Iraq, from the capital city of Iraqi Kurdistan, wrote on X on Thursday: «A miracle no one was injured when 2 drones struck our community, 150 meters from our Catechist Center that serves 1,000 Catholic children. Our university & schools are also closed so the young can be with their parents. Please pray for us & for all who suffer in this war.»
Kurdistan Regional Government authorities confirmed the attack and said it was carried out by two drones.

Phillip Smyth, an expert on Shiite militias in Iraq, told Fox News Digital about the strikes on the Chaldean Catholic school that «Kata’ib Hezbollah was first to talk about it and it was likely Kata’ib Hezbollah, but it is possible it was another two pro-Iran militias because they all work together on drone launches.»
A drone attack struck an oil field operated by U.S. firm HKN Energy in Iraq’s Kurdistan region on Thursday, causing a fire and halting production, according to a Reuters report citing security sources and an oilfield engineer.
No group claimed responsibility, but Kurdish officials accused Iran-allied Iraqi militias of carrying out the attack.
If so, the attack would mean Iran‑aligned Iraqi militias, who have vowed to retaliate for the killing of Iran’s supreme leader, have expanded targets from U.S. military bases in Iraqi Kurdistan to U.S. energy interests.

Production at the field was halted as a precaution after an explosion at its power unit, the engineer told Reuters.
Some energy companies operating in Iraqi Kurdistan shut oil and gas production at their fields as a precaution after the U.S. and Israel launched strikes on neighboring Iran.
Entifadh Qanbar, a former spokesman for the deputy prime minister of Iraq, echoed the comments of the Iraqi Kurdish official in his statement to Fox News Digital: «The Popular Mobilization Forces (PMF) are fully funded by the Iraqi government. In fact, they are formally included as a line item in Iraq’s federal budget. Officially, more than $3 billion is allocated annually just for salaries, but when logistics, weapons, food, and other operational costs are included, the PMF’s budget likely exceeds $10 billion. That is the size of the budget of a small country in the Middle East,» he claimed.
IRAQI STATE BANK ACCUSED OF PROCESSING PAYMENTS FOR HOUTHI TERRORISTS WHO DISRUPT RED SEA COMMERCE
Qanbar said there is a way to change Iraq’s behavior: «If the United States wants to stop this situation, there are clear tools available. Sanctions must be imposed on the Iraqi government for funding these militias. Another powerful mechanism involves Iraq’s oil revenues, which are deposited at the U.S. Federal Reserve. The United States could suspend transfers of those funds unless Baghdad halts the financing of the PMF. Make no mistake: every terrorist who launches drones or rockets against Kurdistan, U.S. interests, Gulf states or military bases is effectively being paid by the Iraqi government,» he claimed.

When asked if the Islamic Republic of Iran urged Shiite militias from the PMF to fire drones at Israel, a spokesman for Iran’s U.N. mission said, «The Mission declined to comment.»
On Tuesday, Iraqi Prime Minister Mohammed Shia al-Sudani said his government is «not tolerating any attempt aimed at dragging Iraq into war or threatening the country’s stability,» according to Kurdistan24.
Salwan Sinjari, chief of staff to the Iraqi foreign minister, referred Fox News Digital to the Iraqi foreign ministry page for official statements by his minister and the government. He did not respond to follow-up messages and calls on whether Iraq’s government was failing to crack down on the PMF.

Iraqi Foreign Minister Fuad Hussein claimed the government was seeking to convince Iran-backed militias to disarm in January 2025, according to the Long War Journal.
However, Iraq’s government has issued mixed messages about the PMF over the years. In May 2025 al-Sudani was quoted as saying, «Today, the Popular Mobilization Forces constitute a basic force in defending Iraq.»
Iraq’s ambassador to the U.S. did not immediately respond to email, WhatsApp and telephone queries. A second Iraqi diplomat said he was unable to provide Fox News Digital a comment.

The Times of Israel reported on Thursday, after military strikes eliminated a senior officer from Kataeb Hezbollah — Iraq’s largest pro-Iran militia — south of Baghdad that PMF militias pledged to strike the Middle East interests of European nations that joined in the «Zionist-American» strikes on the Islamic Republic and its proxies.

Democrats pressure Mike Johnson to keep House in Washington over ‘rapidly developing’ Iran operation

NEWYou can now listen to Fox News articles!
FIRST ON FOX: A group of Democrats is demanding that Speaker Mike Johnson, R-La., keep the House of Representatives in Washington, D.C., next week in light of the «rapidly evolving» situation in Iran.
«The attacks have resulted in heightened threat assessments around the globe as well as multiple deaths, including the tragic loss of six U.S. service members. At this sensitive time, we believe it is in the best interest of our constituents if we remain in session as events continue to develop,» they wrote to the chamber’s leader on Friday.
The letter is being led by Rep. Jared Moskowitz, D-Fla., and nine other members of the House Democratic Caucus, and comes nearly a week after the U.S. and Israel first launched strikes targeting Iran’s senior leadership and military assets.
They’re calling on Johnson to not only keep the House in session but encourage meetings of the committees relevant to U.S. national security in light of the heightened threat environment.

«By the President’s own admission, current military operations against Iran could be sustained for weeks. The rapid developments of such an operation, and its potential impact here at home, require a firm commitment to legislative engagement,» the Democrats wrote.
«If the House of Representatives is absent during such a pivotal moment in our foreign policy, we will be failing our constituents. We urge you to cancel next week’s recess so that we may fulfill our oversight duty.»
Democrats and Republicans’ responses to the operation have largely fallen across party lines.
HOUSE VOTES TO LET TRUMP’S OPERATION EPIC FURY CONTINUE IN IRAN
Democrats have accused the administration of plunging the U.S. into another Middle East conflict without a clear ending while running roughshod over Congress’ constitutional authority. Republicans, meanwhile, maintain that the White House is acting within its authority in the best interests of the country.

The House is out all next week as Republican lawmakers head to President Donald Trump’s Doral golf club in Florida for their annual member retreat, where they will continue to monitor developments in Washington while discussing policy for the remainder of this year.
Democrats had their own annual retreat in late February.
TRUMP SAYS ‘LOSERS’ SCHUMER, DEMS WOULD HAVE CRITICIZED ANY DECISION HE MADE ON IRAN
But as Democrats hammer Johnson for leaving D.C., Republicans are accusing them of playing politics with the national security situation themselves.
House GOP leaders held a vote on funding the Department of Homeland Security (DHS) using a bipartisan bill that Democrats had already walked away from weeks ago, arguing it did not do enough to rein in Trump’s immigration crackdown.
Republicans argued that the ongoing situation with Iran is worsening the effects of the ongoing DHS shutdown, which began after Democrats shunned the initial bipartisan deal.
All but four House Democrats voted against the bill on Thursday.

«They do not want to fund the agencies whose job it is to keep Americans safe at this time of this heightened threat environment that we’re all living in,» Johnson said after the vote. «We’re concerned about sleeper cells in the country. We’re concerned about the safety of every American. And the Democrats are playing politics here.»
A House GOP leadership aide told Fox News Digital in response to Moskowitz’s letter, «Bipartisan majorities in both chambers of Congress just voted to support President Trump and Operation Epic Fury because they know the Iranian regime is a real threat to American security and Middle East stability. By contrast, most House Democrats, including Rep. Moskowitz, voted to keep the Department of Homeland Security closed in order to protect the criminal illegal immigrants they allowed into our country.»
