Chimpanzees Are Capable of Speech, According to New Analysis of Decades-Old Footage

In 1962, many American moviegoers were treated to an unusual display during screenings of the popular Universal Newsreels that aired before feature presentations. That year, a segment entitled “Now Hear This! Italians Unveil Talking Chimp” was shown, introducing audiences to Renata, a chimpanzee who had reportedly been trained to say “mama” by her handler.

“As explained by her foster mother, this is one of the most extraordinary chimps in the world,” announcer Ed Herlihy’s famous voice could be heard saying in the decades-old footage. “You don’t have to know Italian to understand Renata’s accent when she gets her cue.”

Then, as Renata’s handler taps her on the chin, the chimpanzee is shown saying the word “mama” several times.

The footage, likely viewed as little more than a novelty at the time, represented something potentially extraordinary: evidence of a non-human primate displaying the ability to speak, albeit crudely. Despite Renata’s unique talent, the footage was largely forgotten, and prevailing wisdom continued to insist that humans were the only primates with the required neural circuitry capable of speech.

However, Renata was not the only known example of a chimpanzee who displayed a limited ability to learn and speak human words. Decades later, in a video uploaded to YouTube on August 17, 2007, a chimpanzee named Johnny was also shown saying “mama,” seemingly in response to requests from his owner, after which he was awarded a treat.

Misrepresentation of Critical Satellite Data by IPCC

The 6th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6) concluded “It is very likely that well-mixed GHGs [greenhouse gases] were the main driver of tropospheric warming since 1979” (IPCC, 2021; p.5). This statement implies that all known climate forcings have properly been evaluated using the available data, and GHGs have been found to exert a disproportionally large radiative effect on the Global Surface Air Temperature (GSAT) over the past 45 years. However, a close examination of Chapter 7 of the Working Group I (WG1) Contribution to the IPCC AR6 (Forster et al. 2021), which discusses the Earth’s energy budget, climate feedbacks and climate sensitivity, reveals that the observed decrease of Earth’s albedo and the corresponding increase of absorbed shortwave radiation by the Planet for the past 20 years have not been taken into account as contributors to the recent warming. Section 7.2.2 of Chapter 7 entitled “Changes in Earth’s Energy Budget” acknowledges that there have been multidecadal periods of significant decreasing and increasing trends in surface solar radiation (SSR) called “global dimming” (i.e. from 1950s to 1980s) and “global brightening” (after 1980s), respectively. The report states: “There is high confidence that these [SSR] trends are widespread, and not localized phenomena or measurement artefacts.” Indeed, the existence of such dimming and brightening multidecadal periods has been acknowledged by science for more than 10 years (Stanhill et al. 2014; Yuan et al. 2021), but the IPCC AR6 provides no global estimate of the observed positive trend in SSR since 1980s and its impact on GSAT. Instead, the Report simply states “The origin of these trends is not fully understood”.

Hunt for Element 120 Underway as Team Confirms First Creation of Element 116 Using Titanium Beam

In a physics first, scientists at Berkeley Lab have succeeded at creating element 116 using a titanium beam, a development that could set the pace for the creation of heavier elements, including the long-theorized element 120.

The achievement brings scientists closer than ever to creating the heaviest atom ever created by physicists, believed to represent an “island of stability” amid superheavy elements.

With the discovery of 16 of the 118 elements currently known already under its belt, Berkeley Lab’s breakthrough marks a significant step toward bringing such hypothetical elements into existence.

The Hunt for Element 120

Formally known as unbinilium or Ubn, its temporary systematic IUPAC name and symbol, the theorized element 120 (also known by the nickname eka-radium), if officially discovered, would claim its place on the 8th row of the periodic table. For now, the theorized superheavy element is believed to represent an alkaline earth metal or s-block element.

Superheavy elements generally have short lifespans since they have large and very unstable nuclei capable of ripping themselves apart within just seconds of their creation. The instability arises from their size, which results in protons with positive charges within the nuclei repelling each other.

Energy Scientists Invent Device That Draws Electricity Out of Thin Air

A team of scientists from the University of Singapore has announced the creation of a prototype energy-harvesting device that draws usable electricity seemingly out of thin air.

Designed to leverage nanoscale spin rectifier technology to capture what the device’s inventors term “waste RF” signals that exist in the air due to Wi-Fi, Bluetooth, 5G, and traditional radio signals, the novel energy harvesting system can convert those signals into enough usable direct current (DC) electrical energy.

Similar RF energy harvesting technologies have been developed in recent years, including one invented by researchers from the University of South Florida. However, the team behind this latest iteration says their device is able to capture energy from weaker overall signals (typically less than -20 dBm) than even the most sensitive RF energy harvesting technology.

“Harvesting ambient RF electromagnetic signals is crucial for advancing energy-efficient electronic devices and sensors,” explained project leader Professor Yang Hyunsoo from the Department of Electrical and Computer Engineering at the NUS College of Design and Engineering. “However, existing Energy Harvesting Modules face challenges operating at low ambient power due to limitations in existing rectifier technology.”

To overcome the limitations of similar devices, including the inefficiencies of converting such weak signals into useful electricity, the team developed their own ultra-compact, nanoscale spin rectifier technology to capture and convert the waste RF. Unlike previous attempts, this minuscule rectifier showed impressive results at converting RF signals below -20 dBm.

According to Professor Yang, his team’s efforts to improve energy harvesting at these low levels were drastically different from previous efforts. That’s mainly because of the implementation of nanoscale spin rectifiers.

“Recent efforts focused only on improving antenna efficiency and impedance-matching networks at the expense of bigger on-chip footprints,” the professor explained. “Nanoscale spin-rectifiers, on the other hand, offer a compact technology for sensitive and efficient RF-to-DC conversion.”

After trying several configurations designed to convert energy from different low yet usable EM wavelengths, the team settled on something that operated at a level of efficiency previously unseen. This result, the team explains, was due to their approach as much as the technology itself. The result was a device that successfully captured low levels of RF and converted them to enough electricity to power an electrical sensor and an LED.

CHINA DETECTS WATER IN SAMPLES IT COLLECTED FROM THE MOON

Scientists have discovered traces of water while analyzing lunar soil samples collected by China’s Chang’e-5 rover.

While NASA already announced the discovery of water on the Moon’s sunlit areas back in 2020, the new research suggests that water can take on even more forms than previously thought on the lunar surface.

As detailed in a paper published in the journal Nature Astronomy, the samples “revealed the presence of trace water,” tantalizing evidence that “water molecules can persist in sunlit areas of the moon in the form of hydrated salts.”

Lesser-Known Marijuana Components Can Be ‘Promising Anticancer Agents,’ Study On Multiple Myeloma Finds

A new study on the possible therapeutic value of lesser-known compounds in cannabis says that a number of minor cannabinoids may have anticancer effects on blood cancer that warrant further study.

The research, published in the journal BioFactors, looked at minor cannabinoids and multiple myeloma (MM), testing responses in cell models to the cannabinoids CBG, CBC, CBN and CBDV as well as studying CBN in a mouse model.

“Together, our results suggest that CBG, CBC, CBN, and CBDV can be promising anticancer agents for MM,” authors wrote, “due to their cytotoxic effect on MM cell lines and, for CBN, in in vivo xenograft mouse model of MM.”

They also noted the cannabinoids’ apparently “beneficial effect on the bone in terms of reduction of MM cells invasion toward the bone and bone resorption (mainly CBG and CBN).”

SCIENTISTS LOCATE MYSTERIOUS ‘DARK OXYGEN’ ON THE OCEAN FLOOR IN BAFFLING DISCOVERY THAT CHALLENGES IDEAS ON LIFE’S ORIGINS

Scientists have discovered metallic minerals on the deep ocean floor that produce “dark oxygen,” according to findings presented in a new study that potentially upend past assumptions that our planet’s oxygen is produced solely by photosynthetic organisms.

The discovery, made at a depth of 13,000 feet below the ocean surface, shows that oxygen can be produced even in the complete darkness of Earth’s sea bottoms. The new findings could potentially challenge our current understanding of the origins of aerobic life on Earth.

THE DISCOVERY OF ‘DARK OXYGEN’

“For aerobic life to begin on the planet, there had to be oxygen, and our understanding has been that Earth’s oxygen supply began with photosynthetic organisms,” said Andrew Sweetman of the Scottish Association for Marine Science (SAMS), who made the groundbreaking discovery while sampling the seabed of a mountainous submarine ridge in the Pacific Ocean known as the Clarion-Clipperton Zone.

“But we now know that there is oxygen produced in the deep sea, where there is no light,” Sweetman added.

According to Sweetman and his colleagues, the key to the discovery involves polymetallic nodules, natural mineral deposits on the ocean floor. These nodules, some of which can be as small as tiny sand grains and others as large as a baseball, are composed of metals such as cobalt, copper, lithium, manganese, and nickel, all of which are critical for battery production.

NASA built a Moon rover but can’t afford to get it to the launch pad

NASA has spent $450 million designing and building a first-of-its-kind robot to drive into eternally dark craters at the Moon’s south pole, but the agency announced Wednesday it will cancel the rover due to delays and cost overruns.

“NASA intends to discontinue the VIPER mission,” said Nicky Fox, head of the agency’s science mission directorate. “Decisions like this are never easy, and we haven’t made this one, in any way, lightly. In this case, the projected remaining expenses for VIPER would have resulted in either having to cancel or disrupt many other missions in our Commercial Lunar Payload Services (CLPS) line.”

NASA has terminated science missions after development delays and cost overruns before, but it’s rare to cancel a mission with a spacecraft that is already built.

The Volatiles Investigating Polar Exploration Rover (VIPER) mission was supposed to be a robotic scout for NASA’s Artemis program, which aims to return astronauts to the lunar surface in the next few years. VIPER was originally planned to launch in late 2023 and was slated to fly to the Moon aboard a commercial lander provided by Pittsburgh-based Astrobotic, which won a contract from NASA in 2020 to deliver the VIPER rover to the lunar surface. Astrobotic is one of 14 companies in the pool of contractors for NASA’s CLPS program, with the goal of transporting government-sponsored science payloads to the Moon.

But VIPER has been delayed at least two years—the most recent schedule projected a launch in September 2025—causing its cost to grow from $433 million to more than $609 million. The ballooning costs automatically triggered a NASA review to determine whether to proceed with the mission or cancel it. Ultimately, officials said they determined NASA couldn’t pay the extra costs for VIPER without affecting other Moon missions.

“Therefore, we’ve made the decision to forego this particular mission, the VIPER mission, in order to be able to sustain the entire program,” Fox said.

“We’re disappointed,” said John Thornton, CEO of Astrobotic. “It’s certainly difficult news… VIPER has been a great team to work with, and we’re disappointed we won’t get the chance to fly them to the Moon.”

NASA said it will consider “expressions of interest” submitted by US industry and international partners by August 1 for use of the existing VIPER rover at no cost to the government. If NASA can’t find anyone to take over VIPER who can pay to get it to the Moon, the agency plans to disassemble the rover and harvest instruments and components for future lunar missions.

Scientists were dismayed by VIPER’s cancellation.

“It’s absurd, to be honest with you,” said Clive Neal, a planetary geologist at the University of Notre Dame. “It made no sense to me in terms of the economics. You’re canceling a mission that is complete, built, ready to go. It’s in the middle of testing.”

“This is a bad mistake,” wrote Phil Metzger, a planetary physicist at the University of Central Florida, in a post on X. “This was the premier mission to measure lateral and vertical variations of lunar ice in the soil. It would have been revolutionary. Other missions don’t replace what is lost here.”

REAL LIFE TRACTOR BEAMS? GAME-CHANGING NEW TECHNOLOGY COULD LEAD TO NON-INVASIVE MEDICAL PROCEDURES

Tractor beams, a technology once relegated to science fiction, could soon become a practical reality with the help of recent advancements in metasurface research.

Under development by researchers with the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS), the new technology represents “an important first step in the development of metasurface-enabled tractor beams,” which the TMOS team says will be capable of reeling in particles using rays of light.

The science fiction counterparts to this emergent real-life technology have been depicted in films that include Star Wars, where such previously imaginary devices are used to prevent objects such as spacecraft from moving or evading capture.

While real-life tractor beams are still far from matching the power of their fictional analogs, the TMOS researchers say their development of the game-changing new technology draws inspiration from such once-imaginary concepts.

“This work opens new possibilities for using light to exert forces on tiny objects,” said Ken Crozier, the Chief Investigator of the recent research.

MAKING TRACTOR BEAMS A REALITY

The team, led by researchers at the University of Melbourne, reports the creation of a solenoid beam that relies on a special silicon metasurface to generate it.

Solenoid beams have been developed in the past, although these earlier designs mostly rely on devices known as special light modulators, or SLMs. The size of these devices has imposed a limiting factor on their potential use, particularly in handheld applications.

In the team’s new research, outlined in a study that recently appeared in ACS Photonics, they describe the special metasurface developed for their tractor beam technology as an extremely thin (about 1/2000 of a millimeter) layer of nanopatterned silicon, which they believe may one day help to facilitate handheld devices that will allow surgeons to conduct non-invasive biopsies on patients, which would result in less damage to surrounding tissues than current methods.

At the heart of the technology is the understanding that forces exerted by beams of light have the effect of displacing particles, which are moved further from the light source with their passage. However, past research has shown that solenoid beams can draw particles toward their light source, similar to how the grooves in a drill allow the material it cuts into to be pulled upward.

The TMOS researchers say their beam has a few significant advantages over past designs, allowing it to be more flexible and capable of functioning without any need for an SLM. Additionally, its size makes it far more useful in practical, handheld designs while also requiring less power than existing varieties.

NASA SCIENTIST SAYS PATENTED ‘EXODUS EFFECT’ PROPELLANTLESS PROPULSION DRIVE THAT DEFIES PHYSICS IS READY TO GO TO SPACE

A patented experimental propellantless propulsion drive is finally ready to go to space, according to its inventor, a veteran NASA scientist with decades of expertise in electrostatics.

Dr. Charles Buhler, the technology’s creator, says the propulsion system may represent a working version of Quantized Inertia, a theory first proposed by University of Plymouth professor Mike McCulloch. The proposition has been subjected to criticism from mainstream scientists in the past because it seemingly violates Newton’s third law of motion.

The controversial technology, which The Debrief covered in April, is privately owned by Exodus Propulsion Technologies and is not affiliated with NASA.

After almost a decade of research, design, and testing, Buhler says he and his team are confident they have verified the force, one his team calls the Exodus Effect(TM), in “nearly every way conceivable on Earth.” The final step required to officially demonstrate the validity of their discovery is to send the propulsion drive unit into space.

“We’ve done everything we could have in vacuum chambers here on Earth. We’ve tested it every which way you can, but the real validation is to have this thing move in space,” Buhler told The Debrief in a lengthy interview. “That’s the bottom line.”
