Scientists discover how Danionella cerebrum, measuring width of adult human fingernail, can create noises exceeding 140 decibels

One of the world’s smallest fish, measuring about the width of an adult human fingernail, can make a sound as loud as a gunshot, scientists have said.

The male Danionella cerebrum, a fish of about 12mm found in the streams of Myanmar, produces sounds that exceed 140 decibels, according to the study published in the PNAS journal, equal to an ambulance siren or jackhammer.

The most common mechanism in fishes to produce sound involved vibrations of their swim bladder – a gas-filled organ used to control buoyancy – driven by rhythmic contractions of specialised “drumming” muscles, the paper said.


A private lunar lander is expected to cease operations Tuesday, its mission cut short after landing sideways near the south pole of the moon.

Intuitive Machines, the Houston company that built and flew the spacecraft, said Monday it will continue to collect data until sunlight no longer shines on the solar panels. Based on the position of Earth and the moon, officials expect that to happen Tuesday morning. That’s two to three days short of what NASA and other customers had been counting on.

The lander, named Odysseus, is the first U.S. spacecraft to land on the moon in more than 50 years, carrying experiments for NASA, the main sponsor. But it came in too fast last Thursday and the foot of one of its six legs caught on the surface, causing it to tumble over, according to company officials.

Based on photos from NASA’s Lunar Reconnaissance Orbiter flying overhead, Odysseus landed within a mile or so (1.5 kilometers) of its intended target near the Malapert A crater, just 185 miles or so (300 kilometers) from the moon’s south pole.

Multiple corruption scandals fuel support for populist Chega party led by André Ventura

Portugal’s two-week general election campaign has officially begun with centre-right and centre-left parties leading in the polls, but a far-right populist forecast to collect almost a fifth of the vote is a further sign of Europe’s nativist drift.

Prayer room of Great Mosque of Algiers, beset by political wrangling and cost overruns, accommodates 120,000 people

Algeria has inaugurated a gigantic mosque on its Mediterranean coastline after years of political upheaval transformed the project from a symbol of state-sponsored strength and religiosity to one of delays and cost overruns.

Built by a Chinese construction firm throughout the 2010s, the Great Mosque of Algiers features the world’s tallest minaret, measuring 265 metres (869ft).

The third-largest mosque in the world, the biggest in Africa, and largest outside Islam’s holiest cities, its prayer room accommodates 120,000 people. Its modernist design contains Arab and north African flourishes to honour Algerian tradition and culture, as well as a helicopter landing pad and a library that can house up to 1m books.

As the Jorō spider continues to spread across the southeastern United States, its spindly homes can be spotted almost anywhere — even on power lines and stoplights hovering over busy roads.

Typical spiders — and most creatures — tend to find the noise and wind disturbance from nearby busy roads to be too stressful, but the Jorō spider doesn’t seem to mind much, according to a new study published in Arthropoda on February 13. This research could explain why the spiders are regularly spotted in urban areas that native spiders don’t inhabit and suggests the creatures are well-suited to thrive and spread in similar locations throughout the United States.

“If you ever look at a spiderweb next to a road, they’re jiggling and shaking, and it’s a cacophony of stimuli. … Roadsides are a really harsh place for an animal to live. But Jorōs seem to be able to live next to them,” said lead study author Andy Davis, a research scientist at the University of Georgia’s Odum School of Ecology.

Authorities said the man, with serious burn injuries and under critical condition, is being treated at the hospital

A man is in a critical condition after setting himself on fire outside the Israeli embassy in Washington DC, authorities said on Sunday.

The Metropolitan police department said it responded to an incident on International Drive around 1pm to assist the Secret Service. Fire and emergency services said the man had serious burn injuries.

“An adult male was transported by DC Fire and EMS [Emergency Medical Services] to a local hospital where they remain in critical condition,” the police department said on Twitter/X.

A video posted online which showed a man in a uniform shouting “Free Palestine” as he burned and also identified himself as an active US Air Force member, appeared to be the man in the incident, according to multiple officials, the Washington Post reported. An Air Force spokesperson told the Post they had not identified the man, who was reportedly on fire for about a minute before law enforcement put it out.

Ukrainian President Volodymyr Zelenskyy said Sunday that 31,000 Ukrainian soldiers have been killed in action in the two years since Russia launched its full-scale invasion.

Zelenskyy said that the number was far lower than estimates given by Russian President Vladimir Putin’s government.

“31,000 Ukrainian military personnel have been killed in this war. Not 300,000, not 150,000, not whatever Putin and his deceitful circle have been lying about. But nevertheless, each of these losses is a great sacrifice for us”, Zelenskyy said at the “Ukraine. Year 2024” forum in Kyiv.

The Ukrainian leader said that he wouldn’t disclose the number of troops that were wounded or missing. He also said that “tens of thousands of civilians” had been killed in occupied areas of Ukraine, but said that no exact figures would be available until the war was over.

The extent of ice floating around the continent has contracted to below 2m sq km for three years in a row, indicating an ‘abrupt critical transition’

For the third year in a row, sea ice coverage around Antarctica has dropped below 2m sq km – a threshold which before 2022 had not been breached since satellite measurements started in 1979.

The latest data from the US National Snow and Ice Data Center confirms the past three years have been the three lowest on record for the amount of sea ice floating around the continent.

Scientists said another exceptionally low year was further evidence of a “regime shift”, with new research indicating the continent’s sea ice has undergone an “abrupt critical transition”.

Antarctica’s sea ice reaches its lowest extent at the height of the continent’s summer in February each year.

Statement offering support was instead sent by Ursula von der Leyen, Charles Michel and Roberta Metsola.

A statement pledging “unwavering” support for Ukraine from the entire EU was blocked by Hungary, according to two diplomats.

The statement was prepared by the office of the European Council president, Charles Michel, who on Friday afternoon sent an email to member countries, seen by POLITICO, saying that “in the absence of a consensus” among EU leaders, the statement was instead going to be sent in the names of Michel, European Commission President Ursula von der Leyen and European Parliament chief Roberta Metsola. That version of the statement was released Friday afternoon.

Hungary blocked the statement, according to the two diplomats who were granted anonymity to candidly discuss a sensitive topic, with one of them adding that a neutral EU country had doubts about the language used on defense, specifically about missiles, and was also critical that the EU institutions have largely been silent on the Middle East. The three militarily neutral countries in the EU are Austria, Ireland and Malta.

According to Ukrainian magazine Pravda, the missile the Ukrainian air force used to shoot down a rare Russian air force A-50 radar plane on Friday wasn’t an American-made Patriot, as many observers assumed.

No, it reportedly was an ex-Soviet 5V28: the missile component of the S-200 air-defense system.

In retrospect, it should have been obvious that something other than a Patriot shot down the A-50. The lumbering radar plane was around 120 miles from the front line in southern Ukraine when it plummeted to the ground. Where a Patriot usually ranges no farther than 90 miles, a S-200 can hit targets 150 miles away or farther.

We already knew the Ukrainians had reactivated some of their aged S-200 batteries—out of 16 the Soviet air force once maintained all across Ukraine—because they’ve been lobbing them at targets on the ground in occupied Ukraine, and even in Russia itself.

We didn’t know the Ukrainians were firing the brutish missiles at aerial targets until this week.


An embryo is one of the earliest stages of development of a multicellular organism. But according to the Supreme Court of Alabama, it is a person, too — an unborn child, entitled to the same legal protections as any minor.

The court ruled on Feb. 16 that a fertility clinic patient who accidentally destroyed other patients’ frozen embryos could be liable in a wrongful death lawsuit, writing in its opinion that “the Wrongful Death of a Minor Act applies to all unborn children, regardless of their location,” and that this includes “unborn children who are located outside of a biological uterus at the time they are killed.”

This has had immediate and profound consequences on the practice of in vitro fertilization in the state, with many fertility clinics already deciding to interrupt their services for fear of legal repercussions, including the University of Alabama at Birmingham, which has paused its IVF treatments, as has Alabama Fertility Services.

Looks like it does from another article:

Heman’s mentor, 3M product engineering specialist Deborah Isabelle, said she could see the teen’s energy and passion for the project from their first meeting. She described Heman as “focused on making the world a better place for people he hasn’t necessarily even met yet.”

The soap, called Skin Cancer Treating Soap (SCTS), works by using a compound that helps revive dendritic cells, which are killed by cancer cells. Once the dendritic cells are revived, they are able to then fight against the cancer cells. In essence, it reactivates the body’s healing power, Isabelle said.

Similar creams and ointments exist, Heman said, but he doesn’t believe soap has ever been used to fight against skin cancers in their early stages.

He has a five-year plan, which includes seeking approval from the Food and Drug Administration. Isabelle has already connected him with other scientists who specialize in medical products to help him move forward with his plans.

“English is important, but as China develops, English is no longer that important,” said a Weibo post from a nationalist influencer with 6 million online followers after the university’s announcement.

“It should be the turn for foreigners to learn Chinese,” the influencer said.

The downgrade comes as China turns more nationalist and inward under Xi, who has called on the country to strengthen “cultural confidence” and fend off “Western influence.”

In schools and universities, teachers have been forbidden from using Western textbooks or talking about “Western values” such as democracy, press freedom and judicial independence.

This article shows you the updated map:

Across Asia, there has been widespread criticism against China's newly released territorial map. This map includes what is now a "ten-dash line" — an extended version of China's "nine-dash line," which it uses to stake its territorial claims in the South China Sea.

In a thinly-veiled swipe at the United States, Mr Wang said "some country, obsessed with maintaining its hegemony, has gone out of its way to cripple the emerging markets and developing countries".

"Whoever is developing fast becomes its target of containment. Whoever is catching up, becomes its target of obstructions."

The remarks are another development in the growing friction between the US and China - with Mr Xi having earlier blamed the West for the difficulties faced by his country's economy.

These projects, which had questionable profitability to begin with, were hit hard by the country's real estate slump and its zero-COVID pandemic restrictions. The company's cash flows deteriorated, and it has faced numerous lawsuits, including over unpaid bills.
