For Israel’s foremost chiropterologist, every bat is a mitzvah
Bats get bad press. Short-sighted and cave-dwelling, they generally make the news only when carrying disease, transfiguring into vampires, or else lending their name to paranoiac military commanders (e.g. Colonel ‘Bat’ Guano, in Dr. Strangelove).
All of which is grossly unfair — at least according to Yossi Yovel, a professor of zoology at Tel Aviv University, and author of The Genius Bat, recently named a ‘Book of the Year’ by the science journal Nature.
“Usually, bats are very nice,” said Yovel.
Indeed, the flying mammals have been remarkably tolerant towards Yovel and his small team of researchers, who’ve studied bat echolocation for the better part of a decade, and have proved that bats are smarter creatures than previously thought. And only rarely, Yovel said, has he gotten bitten. “But you can’t blame them,” he added. “Because you’re holding them in your hand, and you’re a big creature.”
Yovel first encountered the study of bats, or chiropterology, as an undergraduate at Tel Aviv University, where he took a course on bat echolocation, the first ever held in Israel. He was immediately hooked. “Suddenly, I discovered this new world! Of using sound for vision, basically,” he said.
Sensory zoology, as the broader research field is known, meant Yovel could combine two of his abiding interests: animals and physics. The ways in which animals used sound to get around provoked mathematical questions, not just biological ones.
When Yovel started his research in the late 2000s, he was the first Israeli zoologist to focus explicitly on bats’ sensory behavior. Previously, researchers had only explored bat physiology: how they maintained heat, how they hibernated, what they ate, and so forth. Yovel, by contrast, was “all about sound.”
His most important contribution to the field to date, one described in detail in The Genius Bat, is using GPS devices to track bats and show that they are, in fact, thinking, feeling creatures.
To create the gadgets, Yovel approached an Israeli startup that specialized in manufacturing minuscule GPS instruments — the company had initially designed them in the early aughts, intending to put them inside cameras — with an unusual request: Could they make one that Yovel could stick, using biological glue, to bats?
“So they developed it for me,” Yovel said. “And though the main thing is the GPS, there’s also a microphone in there. And that combination is what’s so unique, because we wanted to record sound echolocation as the bats are flying.”
The research can be hands-on (Yovel attaches the trackers himself) and not without its challenges — chief among them retrieving the devices, which by design fall off the bats within a few days.
Yovel and his team wear antennae, which pick up signals from a “small pinger” attached to the GPS, but still can spend hours searching.
“It’s a huge bottleneck that people are not aware of,” he said. “It’s like a treasure hunt, and often we climb mountains or have to go through thick vegetation.”
To tackle this problem, Yovel and his team constructed a lab — “our own bat colony,” he calls it — at Tel Aviv University, where dozens of bats roost. But the bats are allowed to roam free, so they “go out and come back,” Yovel said.
Thanks to the facility, Yovel can track bats for months, even years, though they haven’t exactly gone undetected. “Sometimes, people complain to me about bats pooping on their cars and on their houses,” he said. “I say to them, ‘tell me where you live, and I can check if our bat visited your backyard or not!”
By studying the bats’ sonar activity, Yovel and his team have shown that bats possess what he describes as a “cognitive map in their brain.” They’ve demonstrated, for instance, that bats can map time, avoiding objects — a tree, say — that they’ve previously visited. “They know that a long time has passed,” said Yovel, “and so they will not return to this tree, because they assume that there’s no more fruit on it.”
Bats even respond to illness in a fairly recognizable manner, often deciding simply to stay at home. “Sick bats will usually avoid any contact, and will not fly out, just like we prefer to be in bed when we’re sick,” Yovel said.
Whether this rises to the level of full-on consciousness is a matter of some debate, though Yovel believes that bats — indeed, most animals — have at least some degree of consciousness. The challenge, then, is finding “sophisticated ways to probe these degrees.” After all, how do you measure such a thing without language as a guide?
He reaches for an unusual comparison to emphasize the dilemma: toddlers. “Pre-lingual toddlers are obviously conscious, right? But we need to find ways to examine this using behavioral experiments, because we can’t ask them,” he said. Artificial Intelligence will certainly play an important role. “That’s the future,” Yovel said. “Using AI models to simulate bat behavior.”
So Yovel will continue to use bats to explore what he calls the “consciousness-gap” between humans and animals. “Or,” he added, grinning a little, “the lack of a gap.”

Iran War Increases Threat to Sweden, Security Service Says

Sweden‘s Security Service (SAPO) warned on Wednesday of increased threats to the Nordic nation from the war in Iran, including risks to Jewish targets, as it released its annual national security assessment.
“History has shown that a desperate and pressured regime can be a dangerous regime,” SAPO operative chief Fredrik Hallstrom told a press conference, referring to the US-Israeli war on Iran.
Iran has long been considered a serious threat, and Swedish authorities have noted how criminal networks – already at the center of a decade-long surge in gang-related violence – have been exploited by state actors to carry out attacks.
“The US-Israeli military operation against Iran, and the countermeasures carried out by Iran, have increased the threat against American, Israeli, and Jewish targets in Sweden,” Security Service Chief Charlotte von Essen said in the report.
In recent years, the agency has also highlighted threats from China and, above all, Russia, which it describes as increasingly willing to take risks in support of its war in Ukraine — including through hybrid operations across Europe.
“Overall, we expect that the threat levels against Sweden will continue to deteriorate in the coming years,” von Essen said, adding that Russia was regarded as a primary driver.
While it is difficult to determine what can be linked to a particular actor, Sweden assesses that Russia is behind several sabotage incidents in Europe targeting critical infrastructure, the security service said. Moscow has denied any involvement.
The agency said it has reviewed hundreds of cases of suspected sabotage in Sweden, including of underwater cables, electricity substations and water-treatment facilities.
“It has so far not been possible to link any physical sabotage to a foreign power,” it said.
The comments came as Iran executed a Swedish citizen on Wednesday, according to Sweden‘s foreign minister, who added that she had summoned the Iranian ambassador in Stockholm to condemn the decision.
The person, who was not named, was arrested in Iran in June of last year and Sweden has repeatedly raised the case with Iranian officials, Foreign Minister Maria Malmer Stenergard said.
“The death penalty is an inhumane, cruel, and irreversible punishment. Sweden, together with the rest of the EU, condemns its application in all circumstances,” Stenergard said.
The legal proceedings leading up to the execution did not meet the standards of due process, she added.
The European Union’s foreign policy chief Kaja Kallas condemned the execution in a statement on Wednesday evening.
“The appalling human rights situation in Iran and the alarming increase in executions are intolerable and show the regime’s true colors,” she said, sending condolences to the family of the citizen.
The Swedish foreign ministry and the Iranian embassy in Stockholm did not immediately respond to a request for comment when contacted by Reuters via phone and email.

Israel Doubles Troops in Hezbollah Fight, Searches Homes in South Lebanon

Israel has more than doubled the number of troops along its border with Lebanon since March 1 and they are searching homes in southern Lebanese villages that the military has ordered evacuated, a senior Israeli commander said on Wednesday.
As Israeli warplanes pound Beirut in operations against Hezbollah that have become the deadliest spillover of the US-Israeli war on Iran, heavy smoke could be seen rising from villages in southern Lebanon as troops fired artillery across the border.
Hundreds of thousands of Lebanese have fled southern Lebanon since Israel ordered people to clear the area south of the Litani River, viewed by Israel as a stronghold of Iran-backed terrorist group Hezbollah. The Shi’ite Islamist group has been firing rockets toward Israel since joining the war in support of Iran on March 2.
‘DEFENSIVE POSITIONS’ INSIDE LEBANON
“The plan is to make sure that Hezbollah does not have military infrastructure,” said the commander, whose name was withheld by the Israeli military on security grounds.
Speaking to Reuters in Eilon, an Israeli town four kilometers from the border, the commander, who is responsible for infantry warfare in Lebanon, declined to say how many troops Israel had now deployed in the area.
Describing the military’s fortifications inside Lebanon as “defensive positions,” he said troops were searching “the villages to see if Hezbollah hid weapons or communications centers.”
Asked if that included searching houses that residents had fled following Israeli orders, the commander said: “In some of the cases they hid their weapons in houses. We have no choice but to make sure that house is not a military installation.”
Two Israeli soldiers have been killed since the start of operations in southern Lebanon, the Israeli military says.
At least 968 people in Lebanon have been killed since the start of Israel‘s attacks, Lebanese authorities say.
Hezbollah has not provided regular updates on deaths among its fighters. On Monday, a Hezbollah official told Reuters that at least 46 had been killed so far.
LEBANESE VILLAGE OF KHIYAM AN INITIAL TARGET
The Israeli military is advancing slowly through southern Lebanon, aiming to completely clear the town of Khiyam as a first step before advancing toward the Litani River, according to a Lebanese security source and a foreign official tracking developments on the ground.
In response to a question on whether Israel intended to establish positions up to the Litani, the commander said it was not his decision. If troops receive orders, he added, they are “prepared to do all kind of operations.”
The Israeli military did not immediately comment on its operations in Khiyam, five kilometers inside the Lebanese border from the Israeli town of Metula.
Along the border near Metula, Reuters saw several Israeli military fortifications dug into hillsides, filled with rows of tanks, armed personnel carriers, and bulldozers.
Smoke rose from Khiyam throughout the day on Wednesday, and many of the buildings on the southern side of the town had been reduced to rubble. A neighboring town remains in ruins from Israel‘s attacks in 2024.
‘EVERY FIVE MINUTES YOU CAN HEAR THE BOMBS’
Israel‘s northern border area with Lebanon is known as the Upper Galilee, its rolling hills offering vantages into southern Lebanese villages now occupied and bombarded by Israeli troops.
Near Metula, Israeli Apache helicopters and jets were making near-constant sorties on Tuesday and Wednesday, with the sounds of rocket fire from Lebanon interspersed with the booms of Israeli artillery fire.
For residents of Israel‘s far north, the current war with Hezbollah has seen less rocket fire than during a year of fighting that ended in 2024.
Hezbollah‘s ability to launch missiles has largely been degraded, but it still retains capacity to strike areas deep inside Israel, Israeli officials say.
Ofer Moskovitz, 60, who works at an avocado farm in the area, and said being so close to the border meant he had little time to run to a bomb shelter when sirens signaled incoming Hezbollah fire.
Near his farm, the military dug out a muddy fortification from where troops fired artillery across the border.
“Every five minutes you can hear the bombs,” he said.

Syria Unveils Plan to Eliminate Assad’s Chemical Weapons

Syria on Wednesday launched a plan supported by Washington to rid the Middle Eastern country of legacy chemical weapons that were used against its people by forces under ousted leader Bashar al-Assad.
For decades, Assad ran a large-scale program for chemical weapons, the use of which killed and injured thousands during Syria‘s long-running civil war.
Despite Damascus’ signing onto the Chemical Weapons Convention in 2013 and declaring a 1,300-ton stockpile, prohibited use continued and the size of the program remains unclear.
An international taskforce backed by the United States, Germany, Britain, Canada, and France, among others, will track down all remaining elements of the program and destroy them under the supervision of the Organization for the Prohibition of Chemical Weapons, Syria‘s ambassador to the United Nations, Ibrahim Olabi, said in an interview.
As many as 100 sites in Syria need to be inspected to determine what toxic munitions remain and how they should be destroyed, OPCW experts have said.
It will require a time-consuming and costly operation to prevent the proliferation of weapons of mass destruction in a region fraught with conflict and political turmoil. The expanding US-Israeli war on Iran and broader regional security concerns will make the timing of the mission uncertain, but all the more necessary to prevent future use, officials said.
GOVERNMENT VOWS FULL ACCESS
Assad was overthrown in December 2024, and the new government under Syrian President Ahmed al-Sharaa has vowed to turn a page and eradicate banned chemical weapons and give inspectors full access.
The move shows that Syria has shifted from a country that was once concealing chemical weapons use to one that is “leading the resolve” to do away with them, Olabi said.
Several international investigations concluded that the nerve agent sarin, as well as chlorine and sulfur mustard gas, was used by the Assad regime, but never revealed the full extent of the clandestine program.
“We don’t know what’s remaining. It was a secret program,” Olabi said. “The job is on Syria to basically look for these things and then declare them.”
A diplomatic source, who spoke on condition of anonymity to discuss the sensitive matter, said the 100 sites could be anything from military bases to laboratories or offices.
“It will probably take many months if not years to get it done, and of course the current situation in the Middle East doesn’t help the process to move forward to the actual destruction of any remnants of Assad‘s chemical weapons program,” the source said.
