☆ But How Does the Worm Get in Your Brain?

Robert F. Kennedy Jr.’s disclosure that a doctor apparently found a dead worm in his brain has sparked questions about what brain parasites are, the damage they can cause and how, exactly, they get there. Brain parasites encompass far more than worms. There are “legions” of organisms that can affect the brain, said Scott Gardner, a professor of biological sciences at the University of Nebraska-Lincoln who specializes in parasites. In addition to worms, common brain parasites include single-celled organisms such as Toxoplasma gondii and some amoeba. The damage varies depending on the type of parasite and where it ends up in the brain.

Sandra TorresTorres has a rare disorder called Laron syndrome that is caused by a genetic mutation. “This is how powerful this mutation seems to be.”What is Laron syndrome? Laron syndrome is a recessive gene, so only those who receive a copy from each parent will be affected. The condition leads to extreme obesity, a trigger for diabetes, heart disease, cancer and other diseases. While technically overweight at 100 pounds (45.4 kilograms), she was in good health, with no signs of diabetes or heart disease.

Strange animal behaviors have been observed at the Fort Worth Zoo during totality, according to researchers stationed in Texas. One of the most bizarre animal observations reported during the 2017 total solar eclipse was of giraffes at other facilities gathering in a herd and beginning to gallop. The giraffes did not gallop this year at the Fort Worth Zoo, but they did huddle together and attempt to enter their nighttime enclosures. The most “dramatic reaction” at Fort Worth Zoo came from the primates. “Right at totality, all of the (gorillas) got up from all quarters of the exhibit and walked directly to where they're supposed to be let in (at night),” Hartstone-Rose told CNN.

☆ Ancient DNA reveals what famed Chinese Emperor Wu may have looked like

CNN —Ancient DNA recovered from the remains of a sixth century Chinese emperor who ruled during the country’s dark ages has shed some light on what the leader may have looked like. Emperor Wu ruled China as part of the Northern Zhou dynasty from 560 to 580 and is credited with unifying the northern part of ancient China during a particularly chaotic period. “Our analysis shows Emperor Wu had typical East or Northeast Asian facial characteristics.”The authors said they hoped ancient DNA might shed light on Wu’s cause of death. The genetic analysis showed that Emperor Wu intermarried with ethnically Han Chinese, China’s dominant ethnic group today. “It’s interesting to see the genetic study, but none of the findings of this genetic study are surprising at all,” Miller said.

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.

But golden tigers — also known as golden tabby tigers or strawberry tigers — are not a subspecies: they’re the result of a genetic mutation that changes the color of their fur. Ramnarayanan spotted the golden tiger, which came within 100 meters of the group, while guiding a safari in the wildlife reserve. The big cat is one of four "golden" tigers in Kaziranga, according to the park's official social media. If Kaziranga’s tiger population becomes more isolated, issues like inbreeding will threaten the population, said Sharma in his post on X.

CNN —Researchers have found a new way in which great apes are similar to humans: they tease each other. Researchers found that all four species of great apes demonstrated “intentionally provocative behavior, frequently accompanied by characteristics of play,” according to the press release. The study details 18 different teasing behaviors, many of which were used to provoke a response or attract another ape’s attention. The authors also differentiate playful teasing, which is one-sided, from play, where both apes reciprocate. While primatologists had observed similar behaviors in the past, the study is the first to systematically study playful teasing, Laumer said.

Paleontologists recently described the previously unknown mosasaur from fossils found near the North Dakota town of Walhalla. The town’s name comes from Valhalla, the feasting hall of Norse mythology where dead heroes gather, so the scientists dubbed the mosasaur Jormungandr walhallaensis. When the scientists examined the skull, they quickly realized they had something unusual on their hands. This combination of traits convinced the researchers that what they were looking at was a new genus and species. Here is a line drawing of the skull of the Jormungandr walhallaensis.

It is unlikely that dengue will become a serious problem in the United States, “as long as people keeping living like they’re living now,” said Thomas W. Scott, a dengue epidemiologist and professor emeritus at University of California, Davis. Outside Puerto Rico and other territories where the disease is endemic, there are about 550 dengue cases each year in the United States, but they are imported by travelers who were infected abroad and passed the disease along to their close contacts. The case in Pasadena is a rare locally acquired case of dengue in the United States. But scientists say dengue will continue to spread to places that haven’t experienced it before. “But I think the general expectation that this is going to be a growing problem in the United States is reasonable.”

However, elements of the flower burial theory didn’t seem to add up. “That was, for us, an indication that maybe there was something going on with the flower burial,” Hunt said. Shanidar Cave in the Kurdistan region of northern Iraq is seen in May.

The woman may have been infected by the worm the same way small animals typically are: by accidentally consuming worm eggs. Carpet pythons were at a lake area near where the woman lived, the article said. She had no direct contact with the snakes but often gathered warrigal greens, which are similar to spinach, from around the lake to cook. The article said that she could have inadvertently consumed worm eggs by eating the greens or because her hands or her kitchen were contaminated by them.

Invasive hammerhead flatworms have distinctive curved heads, striped bodies ranging in color from light yellow to dark brown, and they can secrete tetrodotoxin — a neurotoxin found in puffer fish and blue-ringed octopuses. Five species of invasive hammerhead worms — four in the genus Bipalium and one in Diversibipalium — are established in North America, said Bruce Snyder, an associate professor of biology at Georgia College and State University. Today, most hammerhead worms (also known as broadhead planarians) are concentrated in the Southeast, where they favor warm, damp habitats. Bazzano Photography/Alamy Stock PhotoTo date, more than 3,000 sightings in southeastern states of just one invasive hammerhead species — Bipalium kewense — have been shared to the citizen scientist database iNaturalist.

July 7 (Reuters) - Warm and cuddly are adjectives that seldom spring to mind when one thinks of rattlesnakes. The findings challenge the notion that reptiles are solitary hunters that display little in the way of complex social behavior. Ethology, the study of animal behavior, has long recognized that birds and mammals, including humans, find comfort from being physically close to their own kind. To measure stress levels in the snakes, Martin used a heart-rate monitor designed for humans. "It lets us know as humans that, hey, we're not that different from these snakes," Martin said.
