CNN —An undertaker turned academic, Alexandra Morton-Hayward became interested in brains — specifically how they decompose — during her former job. To understand why, the anthropologist has compiled a unique archive of information about 4,405 brains unearthed by archaeologists. No other soft tissue survived amongst the bones, which were dredged from a heavily waterlogged grave. Morton-Hayward works in a lab in Oxford, England, where she has helped build a collection of 570 ancient brains. Interestingly, many of the oldest brains are preserved in this unknown way, Morton-Hayward said.

☆ Mystery of whale song unraveled by scientists, study says
▼ + stars: | 2024-02-22 | by ( Amarachi Orie | ) edition.cnn.com time to read: +6 min

How baleen whales, which include humpback whales, are able to sing underwater has eluded scientists since whale songs were first discovered more than 50 years ago. A baleen whale’s larynx is shaped differently from other mammals. This structural adaptation allows the leviathan to breathe massive amounts of air in and out when they go to the surface, according to the study. Air sacs also evolved in a way that may allow a baleen whale to recycle air while creating vocal sounds, according to researchers. This means that most boating noises mask calls between baleen whales, reducing the distance over which they can communicate.

The US imposed sanctions against Russian manufacturer Zala Aero, which produces the Lancet drones. The Lancet drone is a loitering munition that stays near its target before crashing into it. AdvertisementAdvertisementThe US imposed sanctions on Thursday against a Russian manufacturer of lightweight drones that has been impeding the progress of Ukraine's counteroffensive. Lancet drones are small and lightweight, with its latest iteration, the Lancet-3M, weighing about 26.5 pounds — including the payload —and measuring less than 6 feet long, The Wall Street Journal reported.

Insider has compiled a list of four of the most effective ones Russia has used so far in the war. Insider has taken a look at four key military systems that Russia has used to do this, from Ka-52 attack helicopters to Lancet drones. Ka-52 "Alligator" attack helicoptersA serviceman checks a Russian Ka-52 "Alligator" attack helicopter. It can also be fitted with VIKHR anti-tank missiles, ATAKA missiles, B8V-20 rocket launchers, and IGLA-V anti-aircraft guided missiles, per the site. Danilov said the number of Russian mines was "insane" and stressed the importance Ukraine was placing on saving its front-line soldiers.

Footage of destroyed Ukrainian vehicles is spreading, often attributed to the Lancet drone. Russian officials have gleefully shared videos of piled-up wreckage, and often cited as the cause the Russian-made Lancet drone.

Drone maker Valeriy Borovyk told CNN that he's building "very stealthy" drones for Ukraine. He said the drones can be used to carry out surprise attacks on "very expensive" Russian equipment. He told CNN that his team is developing some long-range drones, as well. Drone maker Valeriy Borovyk told CNN that he calls the drones "Vidsyich," which is Ukrainian for "repel." "We mostly concentrate [our attacks] on very expensive [Russian] equipment," he told CNN.

Video posted by Ukraine's security agency showed an odd facet of drone warfare. This clip showed a Ukrainian drone smashing into an enemy drone in flight. A video posted Wednesday by Ukraine's internal security service, the SBU, deviated from that norm. The rest of the video shows more conventional drone operations, aimed at what appear to be Russian military supply trucks. A Ukrainian exploding drone closes in on a truck as two people dive for cover in a video published in May 2023 by Ukraine's SBU security agency.

☆ Inside Ukraine’s scramble for “game-changer” drone fleet

It is hoping that domestic drone makers like AeroDrone will help it meet its ambitious goals. The government is now working with more than 80 Ukraine-based drone manufacturers, Ukraine's Defence Minister Oleksii Reznikov told Reuters. RUSSIAN TERRITORYThe range and potency of Ukraine's drones is a sensitive issue. Danilov, the national security council head, acknowledged Ukraine’s reliance on other countries for more high-tech drone components. "We are trying to fulfil our needs in this sector with domestic production, but we realise that it's unlikely we will be able to fulfil everything," he said.

☆ For toothed whales, sound production is all in the nose
▼ + stars: | 2023-03-02 | by ( Will Dunham | ) www.reuters.com time to read: +4 min

Researchers on Thursday offered a comprehensive explanation for sound production by toothed whales - loud clicks for echolocation, and softer burst pulses and whistles for communication. The researchers used sound-recording tags on sperm whales, false killer whales and bottlenosed dolphins to study sound production in the wild. The sounds made by toothed whales differ from the haunting "singing" by filter-feeding baleen whales. "Toothed whales don't sing like baleen whales," Madsen said. During the course of evolution, toothed whales have lost their vocal folds, but evolved an entirely new set of sound sources in the nose."

☆ Military tech is racing towards a dangerous AI future, and Russia's war in Ukraine is paving the way, drone experts say
▼ + stars: | 2023-01-26 | by ( Mia Jankowicz | ) www.businessinsider.com time to read: +8 min

Currently, the drones are guided at launch by a human operator, according to independent Russian outlet Novaya Gazeta Europe. But more advanced drone technology is enabling what Rogers calls "on" the loop of control. "In the case of the systems that we have seen used, there's still a human operator authorizing the use of force," she said. Under pressure and potentially under fire, a drone operator may take the machine's prompt less as a suggestion and more as an infallible instruction. In a fully autonomous future of drone warfare, he asked, will drone AI be programmed "to avoid those who are waving a white flag?"

☆ The tank-killing armored vehicle that France is sending to Ukraine is 'a bit of an oddity,' but don't call it a tank
▼ + stars: | 2023-01-08 | by ( Michael Peck | ) www.businessinsider.com time to read: +6 min

France said on January 5 that it would send the AMX-10RC armored vehicle to Ukraine. The "tank" vs. "armored vehicle" debate is a long and often contentious one, but AMX-10RCs are armored reconnaissance vehicles and not tanks, which usually have large-caliber main guns, heavy-duty armor, and tracks. Fighting there has become trench warfare, with incremental gains rather than sweeping armored offensives in which fast, armored scout vehicles excel. Armored vehicles are still vital on the battlefield, but an armored car may have limited utility against swarms of anti-tank missiles, attack drones, and smart artillery shells. What's important is that the West is sending armored fighting vehicles.

☆ Statins lower the risk of one of the deadliest kinds of strokes, study finds
▼ + stars: | 2022-12-07 | by ( Jen Christensen | ) edition.cnn.com time to read: +5 min

CNN —Doctors know that drugs called statins lower a person’s risk of a stroke due to a blood clot. But a new study shows that the inexpensive medications can also decrease the risk of a first stroke as a result of an intracerebral hemorrhage, the deadliest kind. People in the study who used statins for any period of time had a 17% lower risk of a stroke in the lobe areas of the brain and a 16% lower risk of a stroke in the non-lobe areas of the brain. When they used a statin for more than five years, they had a 33% lower risk of a bleeding stroke in the lobe areas and a 38% lower risk in the non-lobe areas. She said this study shows what biologically makes sense: Taking statins and keeping fatty deposits from building up in the arteries makes hemorrhagic strokes less likely.

☆ Bats use same techniques as death metal singers to vocalize, study finds
▼ + stars: | 2022-11-29 | by ( Zoe Sottile | ) edition.cnn.com time to read: +4 min

CNN —Death metal fans might just have a new animal mascot. Some bats use the same vocal structures as death metal singers to make their unique vocalizations, a new study has found. This allowed the scientists to directly observe the vocal membranes and ventricular folds, also called “false vocal folds,” vibrating at different frequencies. These are “the first direct observations” of these vocal structures in Daubenton’s bats, the researchers said. Ventricular folds, or false vocal folds, are located on top of the true vocal cords.
