Narwhals may be using their tusks to play, new study finds
lucky jet играть
Scientists say they have the first recorded video evidence of narwhals using tusks not only to strike and manipulate fish during feeding but also engage in what appears to be playful behavior, according to the latest research.

The narwhal, often referred to as the “unicorn of the sea” in a nod to its trademark tusk, has long remained an enigma. Scientists have observed few interactions of narwhals in their natural habitat, creating speculation about the purpose of the species’ distinctive spiraling tusk.

Found predominantly in males, the tusk grows up to 10 feet (3 meters) long — and previous research has suggested it serves as a competitive display to secure mates. But now, with the help of drones, research conducted in the Canadian High Arctic has uncovered that a narwhal may use its tusk for more than just courtship.

In total, the researchers newly identified and described 17 distinct behaviors of narwhals involving prey. The findings revealed a wide range of interactions and dynamics between narwhals and fish as well as the extraordinary agility, precision and speed of their tusks to track moving targets, according to the study published February 27 in the journal Frontiers in Marine Science.

“Seeing that these animals are not actually hunting the fish but exploring, manipulating and interacting with it was really a game changer,” said lead author Dr. Gregory O’Corry-Crowe, a research professor in the Harbor Branch Oceanographic Institute at Florida Atlantic University.

Since so little is understood about this whale species, researchers like O’Corry-Crowe and his colleagues are working diligently to conduct studies to document narwhals’ unknown behaviors to better understand how these animals adapt in a rapidly shifting habitat as oceans warm and sea ice melts.
Narwhal exploratory behavior
The study team captured the groundbreaking footage using drones in Creswell Bay, on the eastern side of Somerset Island in Canada’s Nunavut territory, during the summer of 2022.

As the researchers analyzed the footage, they noticed subtle nuances in the narwhals’ behavior. Footage even captured one instance of a narwhal interacting with a fish by repeatedly nudging it with its tusk — which is actually a giant tooth — without attempting to eat it.

When researchers observed a lack of aggression in some interactions between narwhals and fish, they realized these scenarios were more similar to a cat-and-mouse game, in which the animals were chasing or “playing” rather than hunting, O’Corry-Crowe said.

The fish collectors hoping to save rare species from extinction
phantom wallet
In the rural town of Petersham, Massachusetts, 78-year-old Peter George keeps 1,000 fish in his basement.

“Baseball, sex, fish,” he says, listing his life’s great loves. “My single greatest attribute is that I am passionate about things. That sort of defines me.”

All of George’s fish are endangered Rift Lake cichlids: colorful, freshwater fish native to the Great Lakes of East Africa. Inside his 42 tanks, expertly squeezed into a single subterranean room, the fish shimmer under artificial lights, knowing nothing of the expansive waters in which their ancestors once swam, thousands of miles away.

Due to pollution, climate change and overfishing, freshwater fish are thought to be the second most endangered vertebrates in the world. In Lake Victoria, a giant lake shared between Kenya, Uganda and Tanzania, over a quarter of endemic species, including countless cichlids, are either critically endangered or extinct.

But for some species, there is still hope. A community of rare fish enthusiasts collect endangered species of freshwater fish from the lakes and springs of East Africa, Mexico and elsewhere, and preserve them in their personal fish tanks in the hope that they might one day be reintroduced in the wild.

“I’m a hard ass,” George says. “There is hope.”
Insurance
George has been collecting fish since 1948 when, as a four-year-old in the Bronx, he would look after his grandmother’s rainbow fish. He soon developed “multiple tank syndrome” – a colloquial term used by fish collectors to denote the spiral commonly experienced after acquiring one’s first tank, which involves the sufferer buying many more tanks within a short space of time. He has not stopped collecting since.

Now, George sees himself as a conservationist; his tanks contain what is known as “insurance populations” – populations of endangered fish that are likely to go extinct in their natural habitats. He believes that when the time is right, they can be taken from his collection and returned to their homes. “I would never accept the fact that they couldn’t be reintroduced,” he says.

DOGE attempts to enter an agency building led to physical standoff that spilled into court
kra30 cc
A small federal agency that sends money to help communities in Africa became a flashpoint Thursday in the Trump administration’s efforts to shut down foreign aid and reduce the size of the federal government.

A Trump-backed government official, staffers from the Department of Government Efficiency and federal law enforcement entered the offices of the U.S. African Development Foundation on Thursday, and the fight between the Senate-confirmed foundation’s board and Trump administration emissaries spilled into an emergency court fight, according to court records and photos of the in-person standoff captured by the New York Times.

The standoff was quelled when a judge stepped in Thursday afternoon, keeping the foundation’s existing board in place for a few days until a court hearing could take place.

The African Development Foundation, an independent agency that has provided more than $100 million to African farmers, entrepreneurs and community organizations in the last five years, has been among the foreign aid groups that Trump has targeted to eliminate via an executive order he issued two weeks ago. The work of DOGE at the agency so far, the lawsuit says, mirrors how other foreign aid agencies have been dismantled by the Trump administration.

Trump’s plan for the African Development Foundation snapped into action almost immediately, with DOGE staffers meeting with the foundation’s leadership within days of Trump’s February 21 executive order. The Trump administration then told a board member, Ward Brehm, he was being removed from his position, and a new acting chair would be in charge.
Faced with the overhaul, the board held an emergency meeting on Monday to push back, according to a lawsuit filed in federal court in Washington this week. The board decided Trump’s appointee, Peter Marocco — the de-facto acting leader of USAID, another agency Trump has targeted — was not lawfully in the job, and they alerted Congress, the removed board member Ward Brehm’s lawsuit said.

Marocco still showed up at the fund’s headquarters with staffers of the Department of Government Efficiency on Wednesday afternoon. They “were denied access to those offices,” the lawsuit said. “Marocco and his colleagues threatened to return to the offices with United States Marshals and Secret Service.”

Кому будет полезен «форум мам»?
Будущим мамам: Женщины, которые только планируют беременность или уже находятся в ожидании ребёнка, часто нуждаются в эмоциональной поддержке и практических рекомендациях. Форум помогает узнать о том, как лучше
читать
питаться, какие обследования пройти, как подготовиться к родам и избежать распространённых страхов.
Молодым мамам: Первый год жизни малыша полон вызовов: грудное вскармливание, выбор смесей, смена режимов сна и бодрствования, уход за ребёнком в разных сезонах года, профилактика болезней и многое другое. На форуме мам можно найти единомышленниц, которые уже нашли ответы на подобные вопросы.
Опытным родителям: Когда ребёнок подрастает, меняются и задачи: адаптация в детском саду, подготовка к школе, появление второго ребёнка, а позже – выбор кружков и секций. Все эти вопросы также обсуждаются в отдельных тематических ветках.
Папам и другим родственникам: Несмотря на то, что название звучит как «форум мамочек», мужчины и другие члены семьи тоже часто участвуют в обсуждениях, узнавая больше о воспитании и взаимодействии с детьми.
