Shark sounds, molecules Marten and continuous federal cutting
It reduces the federal health and science agency. In addition, the sound of sharks, the meaning of molecules in Martia and has a large claw.

Rachel Feltman: Happy Monday, listeners! For American scientific‘s Science quickly, I’m Rachel Feltman. Let’s launch a week and gather the month with a quick roundin of new sciences.
(Clip: RF is announcing cuts planned on Thursday HHS video: We will delete the entire soup of the alphabet of departments and agencies. “)
Feltman: Last Thursday The US Department of Health and Human Services announced The section plans to cut 10,000 jobs 10,000 full-time jobs. Another 10,000 individuals have already accepted voluntary retirement and purchases. Will knock off the dismissals Food and drug administration, disease control and prevention centers, National Institutes of Health and Medicare and Medicaid Services Centers.

Feltman: HHS Secretary Robert F. Kennedy Jr. said the purpose of these statements is to save money and encourage efficiency.
Meanwhile, last week Trump Administration also led to more than $ 12 billion to cancel the State and local health financing for federal grants. Axios reports The main objectives are initiatives aimed at dealing with health testing grants, health differences and graparations. These cuts from last Thursday were already brought to releases in the Virginia Health Department.
We will see these developments, of course, and they publish you. For now, let’s go to some exciting news of Mars. According to a study published last week US National Academy of Science AcademyNASA’s curiosity Rover has found the largest carbon-based molecules based on the red planet. Long chain albums are believed to come from fatty acids, as the blocks of cell membranes are built in land-living creatures.
Now, these long molecules are not necessarily smoking gun for Martian life. We know that fatty acids can form chemistry instead of chemistry through chemistry. For some scientists think We got fatty acids on the ground first Thanks to the interaction of water and minerals, hydrothermal ventilations. So while the fatty acids are needed, we know, it is possible that it was possible to form Marth; without finding a way without life. Still, this finding is another point in Mars to determine the usual livelihood of the past. Also, these compounds were kept in a 3.7 billion year old rock, The discovery gives scientists hope he if Once the microbial life was Marthen, it may still be able to find signs.
Speaking of superlative size: Paleontologists show a large claw of dinosaurs in poor condition. It corresponds to a new species of terizinosaurs, described Research published in the journal iscience last Tuesday.
Writing National Geographic, Riley Black explained that the therizinosaurs were generally speaking. Dinosaurs fell from carnivores but the plants came to eat. Apparently, apparently, they fell to their three giant claws, except that the giants and feathers were covered. But in 2012, an issue found in the Mongolian Gobi desert has revealed that there are only three fingers to have three fingers.
One finger still has a bargain that would protect the real bone of the claw. This protective coverage Also added Length, Creating a talon almost a long foot. Scientists believe that new species are likely that the third digit is lost as a result of evolution. The sharp claw of sharp creatures seems to be something that would use a tear in prey, probably the branches used hooks, mealsThe authors of the new study believe It could be done more efficient than two fingers than two fingers.
Animal theme We will lead them to collect a couple of new papers on the behavior of animals under the sea. First of all, new research on sharks. Predators are known for their stealth, but he published research in the magazine Royal Association Open Science He is completely bidding. The authors of the studies, on the other hand, is a group of sharks and other elasmobranchas, which includes rays, “they are not historically seen as active sound producers,” researchers were clicked by clicking figures.
The lead of the study heard some unusual sounds when he worked with sharks, at Grad School, but could not be recently investigated. In the new learning, and his colleagues saw 10 rig drawers in tanks exchanged with underwater microphones. The sharks were captured by making very short ways, shorter than man gestures, shorter, literally flashing and lost things. These noises obtained a maximum of 156 decibels, on average. The sharks made much noise when the manipulators touched the first time, and the noises were maintained while they were maintained. This can mean that they are intentionally, “What is the main idea” or “boys, heads, these humans are pretty hands.” But we will need a lot of research to be sure.
And click these like that if you ask:
(Clip: Rig Sharks Click to click Sounds.)
Feltman: Sharks are lacking bladder bladder bladder bladder bladder. The researchers do these clicks to click through “strong” teeth. I can certainly relate to the usual tooth grind mode. Since the sharks are generally speaking, a bunch of teeth is cute, it is reasoned that other species can cause similar sounds.
While the sharks are used to communicate with the sound, the squid is using visual tricks to mix their prey. They know how to quickly change the colors of the squid because of being specialized skin cells and create camouflage patterns. Last month a team of researchers Published examples A species of different visual screen squid can use prey tricks. Scientists were printed with sparking Broadclubs, apparently floating and floating pieces of coral, as well as creating pulsating models that the effect of the dark band is moving the body of the squid. This is a flashing sign that is amazing tactics, which says “chip entry” for man’s eyes. But in a new study published last Wednesday Science advancesThe same researchers argue that this passed screen helps the chip hunt by overflowing the senses of prey animals. From a crab perspective, for example, let them move away from the real movements of the squid to approach these stripes. So there is no full attention to the squid behind the striped curtains!
That’s about this week’s news. We will be back on Wednesday with Special Guests in Wendy Zukerman Science vs Several sexual phenomenon to talk about science behind a great discussion.
