Science Confirms: A Ginger Cat is a Genetic Anomaly

The ginger cat results from a unique genetic variation that, as far as scientists can tell, isn’t found in other species.

A recent survey published in Current Biology reveals that this variation is linked to the faulty expression of a gene called Arhgap36, which has never been associated with the development of mammalian ginger fur.

Interestingly, this gene resides on the X chromosome, which helps explain why most orange cats are male.

Similar to other male animals, including humans, cats possess one X and one Y chromosome. The gene for orange fur is on the X chromosome; therefore, if a male inherits an X chromosome with the orange gene, he will display an entirely orange coat.

Conversely, female cats have two X chromosomes. To display complete orange fur, they must inherit the orange gene from both of their X chromosomes. If they inherit it on only one, the other X may carry a non-orange gene.

This results in a mix of colors in their fur—like the patchy orange, black, and white patterns observed in Calico and Tortoiseshell cats.

The relationship between orange fur and sex applies to cats but not to other orange mammals, such as tigers, orangutans, or red-haired humans.

According to Dr. Christopher Kaelin, Senior Scientist and Lead Author at Stanford Medicine Genetics and Research, the orange mutations in those animals occur due to one of two genes, neither of which are sex-linked.

As a result, orange cats appear to be “genetic exceptions.”

The study confirms that ginger cats exhibit genetic anomalies, but the evidence is still inconclusive regarding whether this unique trait contributes to their reputation for being a mischievous bunch.

To determine if the ARHGAP36 mutation has any impact beyond fur color, researchers have examined various organs, including the kidneys, heart, brain, and adrenal glands, in both orange and non-orange cats, finding no significant differences.

Kaelin remarked, “I don’t think we can exclude the possibility of gene expression changes in untested tissues that might influence behavior.”

He also mentioned that the prevalent notion of orange cats causing chaos could largely be attributed to their male predominance, noting that there is limited scientific research on the personalities of orange cats.

America’s Fascination and Fear of Anomaly Detection: From UFOs to Drones

a While there has been widespread panic over drones and other unknown low-flying objects in New Jersey in recent days, many other parts of the country are still concerned about the very American nature of the skies, which has been resurgent in modern times. A mysterious person is happily captured by a UFO.

At the newly opened National UFO Historical Records Center – A cluster of beige buildings on the grounds of Martin Luther King Jr. Elementary School in Rio Rancho, New Mexico – Literally dozens of files detailing the unexplained flying object and the terror of those around it. It fills the cabinet.

For director David Marler, this first-of-its-kind public archive of UFO historical records is the culmination of a lifelong interest and investigation into UFOs, or UAPs, as the military now prefers to designate them, or unidentified anomalous phenomena.

It came at the perfect time. In recent years, Congressional and Senate hearings have brought the topic, which often rises and falls in public attention during times of national or political unrest, back into the spotlight.

Mahler's collection of UFO books, magazines, magazines, newspapers, microfilms, audio recordings, and case files from the past 75 years is impressive, as well as files from early U.S. Air Force research (Project Sign, Project Grudge, and Project Blue Book). Included. by the National Commission on the Study of Aeronautical Phenomena, the Institute for the Study of Aeronautical Phenomena (formerly based in Alamogordo, three and a half hours away), and the UFO Research Committee of the United States. Akron, Ohio.

A September 13, 1959 military report details an object rotating seven times, marking four military radar stations in New Mexico traveling much faster than the Convair 106, the fastest fighter plane of the time. tracked by.

“The Air Force was interested in national defense in the same way it is today, not from a quote-unquote 'alien perspective,'” Mahler says. “For practical reasons, especially because qualified military and civilian pilots report these things.”

At a Congressional hearing last monthwitnesses claimed that the government was sitting on a trove of information about the UAP dating back decades. Two former Navy pilots said they witnessed first-hand unexplained objects that regularly violate U.S. airspace.

Retired Major David Gruesch, a former member of the Pentagon's UAP Task Force, said the U.S. government has been running a secret program for years to reverse engineer inhuman material taken from crash sites.

However, the United States Old Main Anomaly Resolution Officeor AARO, founded in 2022, said there is no single explanation that addresses the majority of UAP reports, namely “anomalous detections,” and that no evidence of extraterrestrial technology has been found.

AARO Director John Koslosky at Senate hearing said “Reports of unidentified anomalous phenomena, especially near national security locations, must be treated seriously by the U.S. government and investigated with scientific rigor.”

Marler, who has been following the issue relentlessly since he went looking for UFOs with his father when sightings were on the rise in Missouri, says he is neutral on the phenomenon.

“One has to be skeptical, look at the evidence objectively, and suspend conclusions and beliefs,” he says. “What I believe doesn't really matter unless there's data to support it.”

Earlier this year, the New York software company released Enigma, an app that collects sightings by uploading videos and photos with descriptions…

The unexpected weight loss caused by Canada’s gravity anomaly

In certain areas of the world, such as Canada’s Hudson Bay, gravity is slightly lower than in other areas.

This is because an object with more mass has more gravity, and since Earth’s mass is not uniform, gravity varies from place to place. However, you need a very accurate scale to notice it. Hudson Bay’s gravity is about four thousandths of a percent lower than Earth’s average.

When scientists discovered this anomaly in the 1960s, they developed two theories to explain it. The first is that the Earth’s crust is still recovering from the last Ice Age.

About 20,000 years ago, the huge Laurentide ice sheet covered North America. The weight of the ice, which was more than 3 kilometers (almost 2 miles) thick in places, pushed down on the continent’s crust.

When the Ice Age ended, the Laurentide melted rapidly, but the Earth’s crust slowly returned to normal. It rebounds by about 12 mm (0.5 inch) each year, meaning it will take another 300,000 years to return to its original position. This indentation left in the Earth’s crust means that Hudson Bay has slightly less mass and therefore slightly less gravity.

The second theory concerns the movement of the mantle beneath the Earth’s crust.

The mantle is made of molten rock heated by the Earth’s core. It rises over geological time scales and then sinks again as it cools. This creates convection currents that move the plates. Ocean currents can also pull continents downward, slightly reducing mass and gravity in the area.

Satellite measurements in 2002 revealed both theories to be correct. The Hudson Bay gravity anomaly is caused by a combination of mantle convection and the legacy of the Laurentide ice sheet. Therefore, even after the Earth’s crust has fully rebounded, gravity in this part of the world will remain slightly lower than average.

This article answers the question (asked by Victor Gregory via email): “Is it true that people in Canada weigh less?”

Scientists investigate possible anomaly in the force of gravity in the universe

in paper Published in Journal of Cosmology and Astroparticle PhysicsScientists have considered theoretical and observational cases of “cosmic glitches” in the universe's gravity.

Specifically, we develop a model that modifies general relativity on a cosmological scale by introducing a "glitch" in the gravitational constant between the cosmological (superhorizon) and Newtonian (subhorizon) regions.

For the past 100 years, physicists have relied on Albert Einstein's theory of general relativity to explain how gravity acts throughout the universe.

General relativity, proven accurate by countless experiments and observations, suggests that gravity affects not just the third physical dimension, but also a fourth dimension: time. Masu.

“This gravity model has been essential to everything from theorizing the Big Bang to photographing black holes,” said Robin Wen, a researcher at the California Institute of Technology.

“But when we try to understand gravity at the cosmic scale, beyond galaxy clusters, we run into clear contradictions with the predictions of general relativity.”

“It's as if gravity itself is no longer fully consistent with Einstein's theory.”

“We call this contradiction a 'cosmic glitch.' When dealing with distances of billions of light years, gravity weakens by about 1%.”

For more than 20 years, researchers have been trying to create a mathematical model to explain the apparent contradictions in general relativity.

“Almost a century ago, astronomers discovered that the universe was expanding,” said Professor Nyaesh Afsholdi of the University of Waterloo.

“The further away a galaxy is, the faster it is moving, so much so that it appears to be moving at a speed close to the maximum speed of light allowed by Einstein's theory.”

“Our findings suggest that at precisely that scale, Einstein's theory may also be inadequate.”

The research team's “cosmic glitch” model modifies and extends Einstein's formula in a way that resolves some discrepancies in cosmological measurements without affecting existing successful uses of general relativity. This is what I did.

“Think of this as a footnote to Einstein's theory,” Wen says.

“Once we reach the cosmic scale, terms and conditions apply.”

“This new model may be the first clue to the cosmic puzzles we are beginning to solve across time and space,” Professor Afshodi said.

True Anomaly secures $100 million in funding for the expansion of space security technology

true anomaly has closed $100 million in new funding, a strong signal that the appetite for startups operating at the intersection of space and defense is not slowing down.

The new round was led by Riot Ventures with participation from Eclipse, ACME Capital, Menlo Ventures, Narya, 645 Ventures, Rocketship.vc, Champion Hill Ventures, and FiveNine Ventures. The funds will be used to continue expanding all parts of the business, according to a press release.

True Anomaly aims to fill critical gaps in space situational awareness and defensive operations through software and hardware, including a line of autonomous reconnaissance and tracking spacecraft called Jackals. These vehicles are equipped with an array of sensors and cameras to track, monitor, and collect data on objects in space. On the software side, the company is developing an integrated operating platform called Mosaic that will eventually be able to work in conjunction with the Jackal in orbit.

In a previous interview with TechCrunch, True Anomaly CEO Even Rogers pointed to a significant “information asymmetry” between the United States and its adversaries in space. Jackal, Mosaic, and the company’s other efforts in space domain awareness aim to fill that gap.

Founded in 2022 by a quartet of former Space Force members, the startup is rapidly moving towards this goal. During the company’s first full year of business, he opened his 35,000 square foot facility in Centennial, Colorado and doubled his headcount to more than 100 people.

In September, True Anomaly won a $17.4 million contract from the U.S. Space Force to help warfighters find and track objects in space, characterize those objects, and use artificial intelligence to predict changes in space. The agreement was signed to build a suite of space domain awareness capabilities, including prediction and identification. Object behavior.

The first two Jackal spacecraft are scheduled to launch on SpaceX’s Transporter 10 rideshare mission in March. In August, the company received permission from regulators to conduct imaging beyond Earth and demonstrate close space rendezvous operations with two spacecraft. This is such a huge technical challenge that I have no doubt that many people in both Silicon Valley and Washington will be paying close attention to how the demo mission unfolds.
