A look at our changing environment.
Plastics are pretty much everywhere in the modern world including places we want them to be and places where we don’t. Conventional plastics are not biodegradable and instead cause increasing problems wherever they end up after their useful life. As a result, there are global efforts to find environmentally friendly replacements for petroleum-based plastics. An […]
The current administration in the United States is adversarial towards renewable energy and highly supportive of the use of fossil fuels. Unquestionably, this will create rough waters for the clean energy industry and, unfortunately, will throw a monkey wrench into the world’s efforts to mitigate climate change. But it cannot stop what has become a […]
Microplastics come from the breakdown of larger plastics in the environment as well as from direct use in various products such as certain cosmetics. They are found everywhere, from oceans and mountain peaks to the air and water, and alarmingly, in our bodies. They are ingested by all sorts of organisms, from tiny plankton to […]
Researchers around the world are working on what some call the ‘de-extinction’ of iconic animals of the past such as the wooly mammoth, the dodo, and the Tasmanian tiger. The idea is to decipher the genome from DNA of preserved specimens and, using the tools of modern genetic engineering and cloning technology, alter the DNA […]
The White House is considering an executive order that would fast-track permitting for deep-sea mining in international waters and allow mining companies to bypass a United Nations-backed review process. Deep sea mining is the extraction of minerals from the seabed in the deep ocean. Most of the interest is in what are known as polymetallic […]
Researchers at Northwestern University have developed a new method for recycling plastic that is safer, cleaner, cheaper, and more sustainable than those currently in use. The U.S. is the world’s largest plastic polluter per capita, and we only recycle 5% of our plastics. There is a pressing need for better technologies for processing different types […]
Bananas are one of the most widely produced fruits globally, with more than 100 million tons grown every year. They are a key export crop worth approximately $11 billion annually. Bananas are also a staple food in many tropical countries, playing a vital role in both the economies of these nations and in global food […]
About 15% of the Northern Hemisphere is covered by permafrost. Permafrost is soil and sediment that has remained frozen for long periods of time, in some cases as much as 700,000 years. It contains large amounts of dead biomass that has accumulated over millennia and hasn’t fully decomposed. Therefore, permafrost is an immense carbon sink. […]
There has been a great deal of interest in the plight of monarch butterflies in this country. Monarchs’ population and migratory habits are closely watched, and many people have been planting milkweed in their gardens to help their caterpillars. But other butterfly species have received much less attention despite the fact that many butterfly populations […]
Microplastics are a real problem. They are pretty much everywhere. They are in our food, in the oceans, on mountains, up in the clouds, and most alarmingly, in our bodies. All of that is already bad news, but researchers at Boston University have found that microplastics may also be contributing to antibiotic resistance in dangerous […]
Last year was the hottest year on record and the ten hottest years on record have in fact been the last ten years. Ocean heat reached a record high last year and, along with it, global sea levels. Those are rising twice as fast as they did in the 1990s. The World Meteorological Organization reports […]
The largest iceberg in the world, which has been slowly drifting for nearly 5 years, has finally come to a halt. The iceberg – called the unexciting name A-23A – came into existence in 1986 when it broke off from another iceberg A-23 that had calved or torn off from Antarctica earlier that year. For […]
Plastic waste management is a complicated business. Most methods of recycling or breaking down plastic are costly and harmful to the environment. The most common biodegradable alternatives – like paper straws – are less than ideal replacements. There are many approaches to creating biodegradable plastics using feedstocks like seaweed, sugarcane, and other plant matter. However, […]
Alexandria is the second largest city in Egypt and is the largest city on the Mediterranean coast. Its history goes back over 2,300 years and it was once home to a lighthouse that was among the Seven Wonders of the Ancient World and a Great Library that was the largest in the ancient world. The […]
Amphibians are a group of vertebrate animals that include frogs, toads, and salamanders. They are unique for their ability to live both in water and on land during different stages of life. Amphibians play a crucial role in ecosystems, often serving as both predators and prey in food webs. Amphibians are the world’s most at-risk […]
The battery pack in an electric car is the most expensive part of the car. Currently, it accounts for as much as 30% of the price. But EV batteries last a long time. Most are guaranteed for 8-10 years and are likely to last as long as 20 years. In practice, only 1.5% of electric […]
Early March saw more than 200 wildfires break out in the southeastern U.S. – a busy start to the region’s annual fire season. One fire in the Carolina Forest near Myrtle Beach scorched over 2,000 acres over a two-week period and firefighters were busy containing it and many other blazes. Strong winds and an unusually […]
A new study by MIT researchers looked at the potential for grid-edge resources to enhance the ability of the electric grid to respond to unforeseen power outages. Grid-edge resources are devices found close to consumers rather than located near central power plants, substations, or transmission lines. These include residential solar panels, storage batteries, electric vehicles, […]
The 2025 U.S. State of the Birds report was released recently. The report is produced by a coalition of leading science and conservation organizations. The bottom line is that there have been continued widespread declines in American bird populations across all mainland and marine habitats. More than one-third of U.S. bird species are of high […]
We are all familiar with the grout that is used for tiles in our homes. We are less familiar with grout that is used to stabilize the soil beneath buildings. Grouting is a process of ground improvement by injecting materials that can fill voids and cracks, strengthen and increase the bearing capacity of soil, and […]
