☆ The evolutionary twist that could have helped dinosaurs rule Earth
▼ + stars: | 2024-05-18 | by ( Katie Hunt | ) edition.cnn.com time to read: +6 min

New research this week is adding fresh detail to one of paleontology’s biggest questions: Did dinosaur blood run hot or cold? Clues from fossilized eggshells and bones have now suggested that some dinosaurs were warm-blooded and others were not. Reinhard Dirscherl/ullstein bild/Getty ImagesMarine scientists have used artificial intelligence to decode previously unknown complexity in the calls of sperm whales. The whales produced a catalog of clicking sounds, which the researchers described as akin to a “phonetic alphabet” for sperm whales. What sperm whales are saying with their clicks remains a mystery to human ears, but understanding the scope of their vocal exchanges is an important step toward linking their calls with specific behavior.

CNN —Were dinosaurs warm-blooded like birds and mammals or cold-blooded like reptiles? Clues from dinosaur eggshells and bones have suggested that some dinosaurs were warm-blooded and others were not. These dinosaurs may have evolved endothermy, or the ability to internally generate body heat, according to the study. “Warm-blooded animals are generally more active, for example, cold-blooded animals usually don’t build nests,” said lead study author Dr. Alfio Alessandro Chiarenza, Royal Society Newton International Fellow at University College London’s department of Earth sciences. Her 2022 study suggested that ornithischians were more likely cold-blooded and sauropods were warm-blooded.

Now, new research has revealed that there are two distinct species of giant hummingbird in South America — the northern giant hummingbird that lives year-round in the Andes, and the migratory southern giant hummingbird — and they have been evolving separately for millions of years. A southern giant hummingbird is seen flying from its breeding grounds in central Chile. “We wanted to finally solve this mystery.”Designing backpacks for hummingbirdsGiant hummingbirds differ from hundreds of other hummingbird species in many other ways. A southern giant hummingbird is fitted with a tiny backpack-like geolocator tracking device in central Chile. “The two forms of giant hummingbird look almost identical — for centuries, ornithologists and birders never noticed that they were different.

They’re also plumbed by blood vessels, which lead all the way from the heart. By the time blood vessels reach these extremities, like twigs from a tree, they have branched and got much smaller in size. This rare condition is sometimes called “trash foot,” because of the way in which the feet become so discolored. In adults, however, finding the Babinski sign is an altogether different story. In some otherwise healthy people though, the Babinski sign can be observed during deep sleep.

☆ Women have specific exercise and nutritional needs. Dr. Stacy Sims explains

“If we work with our physiology knowing that women are women and men are men, knowing that women are not small men, then imagine the (health) outcomes,” she said at a 2019 TED talk. Women of all ages should focus on strength training to help reduce risk of dementia, said exercise physiologist and nutrition scientist Dr. Stacy Sims (not shown). Dr. Stacy Sims said women should prioritize eating more protein to support building muscle, especially as bodies age. But if we have that lean mass from strength training, it really helps calm down that rate of change. Drinking something cold right after exercise helps bring that blood back centrally, reduces metabolites and starts the reparation process.

☆ Why don’t humans have tails?

One of those led to shorter tails; the more of that protein the genes produced, the shorter the tails. A tail as old as timeFor modern humans, tails are a distant genetic memory. While Alu’s role “seems to be a very important one,” other genetic factors likely contributed to the permanent disappearance of our primate ancestors’ tails,” Xia said. In their experiments, the researchers found that when mice were genetically engineered for tail loss, some developed neural tube deformities that resembled spina bifida in humans. “Maybe the reason why we have this condition in humans is because of this trade-off that our ancestors made 25 million years ago to lose their tails,” Yanai said.

There's actually a reason — and it has to do with the same avian flu outbreak that made eggs so expensive last year. AdvertisementLast year, egg prices went through the roof, with prices more than doubling in certain US states. Because so many chickens died from the flu, egg producers had to adapt. The good news is that egg prices have normalized, thankfully (although they're still more expensive than 2019). That means the worst of the flu outbreak is over, and production is back up.

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. University of Georgia ecology students and study coauthors Kade Stewart, Caitlin Phelan and Alexa Schultz handle a Jorō spider. What to do when you come across a Jorō spiderAs the nonnative Jorō spider continues to spread in the region, the spiders pose a threat to native species that are beneficial to the environment. While conducting the study, the researchers found evidence of the Jorō spiders coexisting with native spiders, Davis said. And the Jorō spiders eat species that are good and bad for the environment, including the infamous lantern fly, he added.

In fact, weekend warriors in the study spent 147.6 minutes — almost the entire recommendation for a week — in each exercise session over the two-day period.

They found that 10 countries, including Kenya, Morocco, Niger, Yemen, and Pakistan, experienced the majority of locust outbreaks among 48 affected nations. The researchers also found a strong link between the magnitude of desert locust outbreaks and weather and land conditions like air temperature, precipitation, soil moisture, and wind. El Nino, a recurring and natural climate phenomenon that affects weather worldwide, was also strongly tied to bigger and worse desert locust outbreaks. “As such variability increases, it is logical to predict that locust outbreaks will increase as well,” said Tallamy. The desert experienced locust outbreaks in 2019 after uncontrolled breeding following cyclones, which filled the desert with freshwater lakes.

CNN —The longstanding problem of pulse oximeters providing less-accurate readings for people with dark skin tones is getting another look from a panel of experts for the US Food and Drug Administration. The FDA’s Anesthesiology and Respiratory Therapy Devices Panel of the Medical Devices Advisory Committee is meeting Friday to review ways to better evaluate the accuracy and performance of pulse oximeters in patients with darker skin. Pulse oximeters are fingertip clamps that send light beams through your finger to estimate the oxygen saturation of your blood and your pulse rate. “That standard is then applied to all people as a one-size-fits-all, but time and again, we have seen in medicine that this approach leads to poor outcomes for certain groups, especially Black patients,” Ibekie said. “We need to address the root and work harder to conduct research with patients that represent our populations as a whole,” she said.

LOS ANGELES (AP) — Extreme heat and wildfire smoke are independently harmful to the human body, but together their impact on cardiovascular and respiratory systems is more dangerous and affects some communities more than others. A study published Friday in the journal Science Advances said climate change is increasing the frequency of both hazards, particularly in California. The authors found that the combined harm of extreme heat and inhalation of wildfire smoke increased hospitalizations and disproportionately impacted low-income communities and Latino, Black, Asian and other racially marginalized residents. Homes and work places with air conditioning and neighborhoods with tree canopy cover are better protected from extreme heat, and some buildings filter smoke from wildfires and insulate heat more efficiently. “For a variety of reason, they tend to feel climate change much worse than other non-underserved communities, and I think it's really important to highlight this social injustice aspect of climate change,” said the emergency physician and fellow at the Harvard T.H.
