Molly Russell Charity allegedly received donations from Meta and Pinterest for Internet Safety purposes.

A large donation was reportedly made to the Molly Rose Foundation by Meta and Pinterest, two major companies in the online sphere. The foundation was established as part of the Internet Safety Campaign and is named after Molly Russell, a 14-year-old who tragically took her own life in 2017 after being exposed to harmful content related to suicide and self-harm on social media platforms.

The latest annual report of the foundation mentions grants received from anonymous donors, with the stipulation that the details of the donations remain private as requested by the trustee.

According to reports from the BBC, Meta and Pinterest are believed to have made these donations starting from 2024 and are expected to continue for the foreseeable future. The exact amount of the donations has not been disclosed, but it is known that the Russell family has not received any financial compensation from the contributions.

In a statement, the Russell family expressed their commitment to utilizing the funds for the shared purpose of promoting a positive online experience for young people, as a response to Molly’s tragic passing. They clarified that they will never accept any compensation related to Molly’s death.

These donations come at a time when social media companies are facing heightened scrutiny for the impact of their platforms on the mental health of children. Meta announced significant policy changes, including the removal of fact checkers to enhance freedom of speech and reduce censorship, relying on users to report objectionable content instead.

The Molly Rose Foundation has raised concerns about the heightened risk of young people being exposed to harmful content online due to these changes. They have launched campaigns advocating for stronger online safety regulations and increased accountability for content driven by algorithms.

The charity has recently expanded its team, recruiting a CEO, two public policy managers, a communications manager, and a fundraiser in the past nine months. Molly’s father, Ian Russell, serves as the foundation’s unpaid trustee and continues to be a prominent figure in internet safety advocacy.

Both Meta and Pinterest were contacted for comments by The Guardian but have not responded at the time of reporting.

Potential harmful effects of banning teenagers’ smartphone use for academic purposes

According to a major academic mission by the UK government to review the impact of smartphones on teenagers, a blanket ban is considered “unrealistic and potentially harmful.” Amy Oben, a former member of Cambridge University, leads the research on children and smartphone use commissioned by the Department of Science, Innovation and Technology (DSIT), along with other academics from various UK universities.

Despite resistance from the Minister to impose new legal restrictions on social media and smartphones for children, beyond existing online safety laws that protect against harmful content, some lawmakers are advocating for further restrictions such as limiting access to social media for individuals under 16, a complete ban on smartphones in schools, or regulating social media algorithms that expose young teens to addictive content.


A recent paper by four co-authors of the British Journal of Medicine (BMJ) argued that bans and restrictions are ineffective, although they acknowledged the importance of providing children and teens with phone-free spaces.

The paper highlighted the challenges of protecting youth from potential harms of technology while also recognizing the benefits of information access and social support provided by smartphones and social media.

Researchers emphasized the need for a nuanced approach, acknowledging that there is no one-size-fits-all solution and that banning devices could hinder children’s rights to access beneficial technologies that support their development.

The Science and Technology Secretary, Peter Kyle, appointed Orben to lead further research on the impact of smartphones on child health and welfare. Orben emphasized the complexity of understanding the digital impact on youth and the importance of generating quality evidence for informed decision-making.

Ministers face pressure to address the use of smartphones by teenagers, especially concerning harmful online content. Discussions about restrictions on social media algorithms for teens and bans on smartphones in schools are ongoing.

Education Secretary Bridget Phillipson is reviewing guidelines on smartphone bans in schools to assess their effectiveness, while Prime Minister Kiel Starmer is engaging in discussions with stakeholders to address potential harm associated with smartphone and social media use.

DSIT has been approached for comment on this matter.

Butterflies harness electrostatic forces for pollination purposes

Have you ever found yourself sitting in your favorite overstuffed armchair and finding your coffee just out of reach? In situations like this, a Jedi could easily deflect a blaster bolt or recover a lost lightsaber. I often wish I could use the “Force”, a mythical energy field used to bring back . In the real world, humans cannot use telekinesis to manipulate objects. But some animals do It uses natural electric fields to attract and repel objects.

The lowercase f “force” exerted by the animal kingdom is caused by friction between two objects, causing one object to lose electrons and the other to gain electrons. static electricity. Since electrons are negatively charged, objects that have lost electrons accumulate a positive charge, and objects that have gained electrons accumulate a negative charge. of electrostatic force Charged objects repel those with the same charge and attract those with the opposite charge. When you rub a balloon against your head, the friction causes the balloon to become negatively charged and your hair to become positively charged, causing your hair to stand on end.

like the force star wars The universe and animals use electrostatic force for both good and evil. In “Light Side” bee, bumblebeeand hummingbird Static electricity builds up as the wing moves through the air. These pollinators use electrostatic forces to transport pollen to and from flowers, supporting plant reproduction and biodiversity. On the “dark side” (at least from the prey's point of view!), predators like orb spiders use electrostatic forces to trap prey in a nestparasites such as mites and mites use it to connect to host.

Scientists suspect that other winged animals use “light-side” electrostatic forces to aid pollination, but it is unclear how widespread this phenomenon is in nature. Not yet. Two biologists from the University of Bristol investigated whether butterflies and moths are members of the order Lepidoptera I did electrostatic pollination. Scientists believe that moths wide range of pollinatorsHowever, opinions are divided as to whether butterflies pollinate plants.

The researchers collected wild butterflies and moths from across the UK and Germany, or purchased captive-bred versions. butterflies of the world. They were kept in climate-controlled mesh enclosures that mimicked their natural habitat and fed artificial flowers and pineapple slices filled with a sugar solution.

The researchers hypothesized that because lepidopterans have relatively small wings and flap slowly, they may be less electrically charged than other pollinating insects. To test this, they measured the static electricity of 72 adult peacock butterflies in free flight. They transferred each butterfly to an acrylic box lined with leaves native to its habitat to ensure that the charge the butterflies carried was as close to natural as possible.

Next, the ring-shaped electrode was attached to a device called “Electric Signal” that detects extremely weak currents. picoammeter. They placed a ring electrode next to the box's exit hole and used a picoammeter to record the charge on each butterfly as it flew out of the hole and passed through the electrode. They found that peacock butterflies have an average charge of about +50 picocoulombs. This is actually more than any other pollinating insect.

The researchers then tested whether the insects' habitat and ecology influenced their static electricity. They used similar techniques to measure charges in four additional species of butterflies and six species of moths across five continents, different climates, and feeding behaviors. They found that all 197 individuals tested carried enough electrical charge to displace pollen grains from several millimeters away. However, the strength and polarity (whether it was positive or negative) depended on the insect's habitat and ecological niche. For example, tropical species are more likely to be negatively charged than temperate species, and nocturnal foragers are more likely to be negatively charged than daytime foragers.

The researchers concluded that butterflies are actually good at pollination. The researchers speculated that the high charge may improve the insect's “light side” ability to attract pollen and sense electric fields around nectar-containing flowers. However, carrying a high charge also has its drawbacks, as highly charged insects are more vulnerable to “dark side” predators and parasites. They suggested that tropical and nocturnal Lepidoptera may be negatively charged. detect predatorsare more active in warm weather and at night. May the electrostatic forces be with them!

NASA to Send Wooden Satellites Into Space for Innovative Research Purposes

In 1957, the first man-made object was successfully launched into space and into orbit around the Earth. This was Sputnik 1, a beautifully simple Soviet spherical satellite with only four antennae.

But this historic event also marked the beginning of another, more disturbing one. It means that humans left the first space debris in orbit around the Earth.

Part of the 267-ton, 30-meter-tall rocket that launched Sputnik also became stuck in orbit. Suddenly, the world was faced with a problem we didn’t know we needed to solve: outer space littering.

Thankfully, Sputnik and the rocket debris it left behind deorbited shortly after launch and burned up in the atmosphere. However, this was not always the case. Just 66 years of space exploration has left vast amounts of detritus in orbit around Earth.

Now, NASA and the Japan Aerospace Exploration Agency (JAXA) are considering ideas to help solve this problem. The idea is to build a satellite out of wood, a widely available biodegradable material.

Space junk is currently a problem

The problems that government agencies are trying to address are big and complex, and they need to know how big the first phase of the project was. At least 130 million pieces of man-made debris are known to be orbiting the Earth, most of them flying at speeds of more than 7 kilometers per second. This is eight times faster than a normal bullet. But while this is a staggering number, some scientists believe it is a conservative estimate.

Most objects sent into space remain in space until either they deorbit and burn up on re-entry, or they are pulled away from Earth into graveyard orbits, where they orbit for hundreds of years. The majority of such objects are actually very small, less than 1 cm in diameter, from paint chips to small pieces of electronic equipment to pieces of insulation foam and aluminum.

Such tiny pieces cannot be seen from Earth, even with powerful telescopes. Therefore, we need to look for evidence left behind when it collides with other objects in space. This is no easy task.

Work to assess the scope of the problem began in earnest after five extraordinary objects, the NASA Space Shuttles, repeatedly orbited and returned. Since 1981, NASA has launched a total of 135 shuttle missions.

After each shuttle returned to Earth, it was evaluated using a fine-tooth comb to identify damage caused by orbital debris. This gives NASA a clearer picture of the problem of small pieces of dead satellites flying through space.

NASA scientists have discovered exactly what they expected: small pieces of debris just a few millimeters in diameter can cause small but powerful impacts. NASA also produced the first estimates of how degraded the debris environment is.

Prior to 1978, NASA scientists Don Kessler and Barton Coolpare had proposed a scenario they named Kessler syndrome. The phenomenon they discussed is a catastrophic event in which when a satellite is shattered by space debris, the resulting debris destroys more satellites, creating even more debris, repeating an endless chain of events. It is a chain of

Obviously, this is a big problem. So how can we slow down the rate of debris formation or eliminate it altogether? Proposed solutions include using radiation hardening to reach space within five years of launch. It involves taking the ship out of orbit.

materials (designed to be less susceptible to damage from exposure to the high levels of radiation and extreme temperatures experienced in space) and launches on reusable rockets.

Incorporate the idea of ​​a wooden satellite. LignoSat, the name of the NASA and JAXA project, is a coffee machine built using traditional Japanese joinery techniques that houses electronics and other materials needed for space missions, much like today's CubeSats. It is a cup-sized (approximately 10x10x10cm) wooden box.

Wood samples were tested for suitability over 290 days in 2022 on the International Space Station's Kibo Japanese Experiment Module.

Magnolia coped well and performed best when exposed to intense cosmic rays and extreme temperature changes in its harsh environment. It does not burn, rot, crack, or deform, and has the important property that upon re-entry into the atmosphere, it burns up to a fine ash, leaving behind small fragments.

Another advantage of wooden satellites is their reflectivity, or rather their lack of reflectivity. Currently, reflections from aluminum satellites are so bright that they can be easily spotted from Earth with the naked eye. Importantly, this reflected light can reach sensitive areas and interfere with astronomical observations.

LignoSat test launch is currently scheduled for 2024. Success could pave the way for further missions.

So will all satellites be made of wood in the near future? Unfortunately, that is unlikely. On the plus side, projects like this encourage researchers to think outside the box and can have a greater impact in the future. If LignoSat is successful, more research groups may try to introduce biodegradable materials to reduce further debris generation.

But for now, I strongly support efforts to actively track as many objects in Earth orbit as possible to reduce future collisions with matter in space.
