MicroplasticsMicroplastics, or MPs, are tiny plastic particles less than five millimeters long and have become one of Earth's most widespread pollutants. Like synthetic plastics, MPs are mostly made of long chains of hydrogen and carbon atoms, formed by linking byproducts of refining crude oil and natural gas. Other chemical additives may be incorporated to modify the final product’s properties. Primary MPs, such as microbeads, are intentionally manufactured to be small. Secondary MPs, such as those released while washing synthetic textiles, form from the breakdown of larger plastics and make up the bulk of MPs in the environment. As of 2024, the FDA claims there is insufficient evidence that MPs pose any human health risk, though initial biochemical studies have linked them to inflammation and hormone disruption.Explore Microplastics

Plastic debris across the ocean aids the spread of invasive speciesThe durable, long-lasting material can serve as a platform for living organisms to latch onto and ride over vast distances. After the 2011 earthquake and tsunami in Japan, a large dock carrying 100 tons of living organisms native to Japan washed up on Oregon's coastline, confirming the ecological threat. VICE NewsThe most common type of 3D printer fabricates objects using plasticAt the consumer level, the most common printing method is fused deposition modeling, which builds objects by melting an extruding thermoplastic filament that is deposited in layers. For industrial applications, selective laser sintering, which uses a laser to fuse particles of polymer powder (e.g., nylon), is preferred. FormlabsAfter swallowing 23 pieces of plastic, seabirds experience a 90% death rateResearchers found that this threshold is also met when marine mammals ingest 29 pieces and when sea turtles consume approximately 405 pieces. Almost half of the sea turtles, a third of the seabirds, and one in ten of the marine mammals studied had eaten plastic. BBC NewsShrink-wrap is created through a treatment of plastic with high-speed electronsAtoms in polyethylene are bonded in long strings called polymer chains, which can be destabilized by removing hydrogen atoms via collisions with electrons. These gaps serve as bonding sites for neighboring chains to bond and undergo cross-linking, strengthening the plastic while making it more malleable. TediumHenry Ford built a plastic car from soybeans in 1941To pursue his goal of marrying industry with agriculture, among other reasons, the automobile giant oversaw the design and creation of a vehicle with 12 panels made from plastic. At 2,000 pounds, the car was much lighter than all-steel ones, but production stopped during World War II. The Henry FordBPA-free plastics often contain other harmful 'forever chemicals'These molecules are widely used in single-use plastics, may leach into food, resist breakdown, and can build up in the human body. They have been linked to obesity, heart disease, and neurological issues, particularly when heated. Insider ScienceNanoplastics can bypass the blood-brain barrier and may harm the nervous systemNanoplastics are formed from the breakdown of microplastics and can breach cells. Their large surface area relative to size allows them to carry higher concentrations of forever chemicals than the surrounding environment into sensitive organs. It's ComplicatedMost biodegradable plastics don’t break down in everyday conditionsDespite their eco-friendly name, biodegradable plastics often require industrial composting, which most areas lack, to decompose the uncommon compounds found in them. This means they may linger in landfills or contaminate conventional plastics in recycling bins. The New York TimesPlastic's history began with an inventor seeking a $10,000 prize offerIn 1869, the first synthetic polymer—celluloid—was created as a substitute for ivory in billiard balls. It became the historical catalyst for the eventual manufacturing of plastics everywhere as an alternative to the depletion of other natural resources, including tortoiseshell and horns. Science History InstituteThe prevalence of microplastics came from plastic’s affordability and versatilityMicroplastics' durability and overuse have led to massive pollution that overwhelms the planet's ecosystems. Avian, terrestrial, and marine life have been observed to contain microplastics in their bodies, but reverting to paper, cotton, and other materials in manufacturing also brings environmental challenges. KurzgesagtJapanese scientists develop an eco-friendly plastic that dissolves in saltwaterThe strong and flexible plastic is made from molecules held together by saltwater-sensitive chemical bonds. The components left after the plastic breaks down within hours contain phosphorus and nitrogen, allowing them to serve as soil fertilizer. ZME SciencePlastivores are plastic-eating microbes that may provide a solution to plastic wasteIdeonella sakaiensis, a bacterium found in recycling plant sludge in 2016, was the first organism seen to possess enzymes that could break down PET, a type of plastic. Researchers continue to search and try to bioengineer microbes that can digest other plastic types. TED-EdA UN-led treaty may establish rules to phase out plastic globallyWith support from more than 175 nations, a treaty led by the United Nations is being negotiated to establish enforceable global rules for plastic production and pollution by 2025. Negotiations come as the total amount of plastic in the ocean has increased by 50% from 2017 to 2022. World Wildlife FundMore than 130 nations have enacted bans or restrictions on plastic itemsSeveral US states have enacted similar restrictions on plastic bags, straws, food containers, and other single-use plastics, while others have prohibited plastic bans. Despite this, California’s plastic bag ban cut usage by more than 70%, showing the potential of these policies. SolinatraMermaid tears are a lasting and hazardous form of ocean plastic pollutionAlso known as nurdles, these tiny plastic pellets are extremely difficult to remove once spilled. Their chemical composition, which enhances absorption, causes them to contain higher concentrations of certain toxins than the surrounding environment. NewsweekPlastics don’t biodegrade because their chemical bonds are unnatural to microbesDespite coming from petroleum, which itself comes from organic material, synthetic plastic was not mass-produced until the mid-20th century. Insufficient time has passed for microbes to develop the necessary enzymes to break it down naturally. Live SciencePlastic production starts with crude oil and ends with molded products via pelletsPolyethylene and other plastics are formed by combining ethylene and propylene, which are produced through refining crude oil. These plastics are formed into pellets called nurdles, which are melted and molded to manufacture countless products. FactoraMicroplastics are everywhere and pose growing risks to wildlife and ecosystemsThese tiny plastic particles come from intentionally small items and the breakdown of larger plastic debris, ending up in soil, air, and water. A study of 37 US National Park beaches found microfibers at every site, making up 97% of all microplastic debris. NOAASynaptic plasticity allows neurons to communicate effectively and form memoriesFirst proposed in 1949, synaptic plasticity allows the brain to adjust communication strength between neurons. This ability to change synaptic strength—either briefly or over long periods—is essential for learning and memory, with long-term synaptic plasticity forming the basis of how memories are stored.
