No need to overload your cranberry sauce with sugar this holiday season − a food scientist explains how to cook with fewer added sweeteners – Cranberries are one of my favorite seasonal foods. I like them so much that I buy enough to freeze and use well into spring – even summer. During the cold months I use them for relishes, adding to stir fry veggies, and in muffins. I’ll make the relishes more savory than sweet from now on!

Researchers Investigate Sustainable Ancient Construction Techniques – Studying the best-preserved earthen building in the Mediterranean. It was built between the eighth and sixth centuries BCE.

Floating Wetlands Bring Nature Back to Baltimore’s Inner Harbor – Built as part of the National Aquarium. The article interested me since we lived near Baltimore for so many years.

Check Out the Highest-Resolution Images Ever Captured of the Sun’s Entire Surface – Images from European Space Agency’s (ESA) Solar Orbiter.

Climate change and air pollution could risk 30 million lives annually by 2100 - Under the most probable projection, annual mortality rates linked to air pollution and extreme temperatures could reach 30 million/year by the end of the century. In 2000, around 1.6 million people died each year due to extreme temperatures, both cold and heat. By the end of the century, in the most probable scenario, this figure climbs to 10.8 million, roughly a seven-fold increase. For air pollution, annual deaths in 2000 were about 4.1 million. By the century's close, this number rises to 19.5 million, a five-fold increase. And yet – there is not the political will to change the scenario.

Vincent van Gogh’s Brilliant Blue ‘Irises’ Were Originally Purple – The paint faded since the painting was created in 1889. It’s still beautiful – either way.

Bee alert: Pesticides pose a real threat to over 70% of wild bees - Alarming risks that pesticides pose to ground-nesting bees (i.e. bumblebees, squash bees), which are crucial for pollination and food production.

The Chilling Sound of the Aztec Death Whistle - Creating 3D digital reconstructions of original Aztec death whistles…then recording sounds from originals and the reconstructions. Both produced sounds like a human voice or scream. There is a link to recording samples at the bottom of the post.

Overwhelmed by ever more clothing donations, charities are exporting the problem. Local governments must step up - There are more and more clothes in circulation, and they are getting cheaper and lower quality. That means the clothes you give away are worth less and less. Worldwide, we now dump 92 million tons of clothes and textiles a year, double the figure of 20 years earlier. Local governments usually handle other waste streams. But on clothes and textiles, they often leave it to charitable organizations and commercial resellers. This system is inherited from a time when used clothing was a more valuable resource, but the rising quantity of clothing has pushed this system towards collapse.

Oysters as large as cheese plates: How New Yorkers are reclaiming their harbor’s heritage – Perhaps the main accomplishment of the project, even more than increasing oyster population, is reminding New Yorkers that they are islanders. It's hard to care about something that is only abstract, something you don't have experience with. Ultimately, people have a much greater ability to improve water quality than the oysters ever will.

Old Growth – Mitch Epstein photographs of very old trees.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

• Embedding well-being into curricula for broader, more accessible adoption.

• Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

• Tailoring initiatives to the student body and university culture.

• Securing buy-in from faculty.

• Ensuring new offerings are accessible and don't create additional financial burden for students.

• Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

Does Cooking with Gas Stoves Hurt Indoor Air Quality? – Yes…but how much is the better question. 12.7% of current childhood asthma in the United States is attributable to gas stove use.

A quick look inside a human being – Magnetic Particle Imaging (MPI)…using a portable scanner to visualize dynamic processes in the human body such a blood flow.

Why it's so important to figure out when a vital Atlantic Ocean current might collapse - Humans are changing the fundamental processes of the Earth faster than we can understand them. The collapse of the current would have effects around the planet: temperatures in Europe would fall, heat in the tropics would rise, rainfall would decrease across the Sahel in Africa, the summer monsoon would weaken across Asia, and sea levels would rise even faster in the eastern US.

New Thermal Activity on Geyser Hill in Yellowstone National Park – Short video from the Yellowstone Volcano Observatory.

‘Perfectly Preserved’ Glassware Recovered From 2,000-Year-Old Shipwreck – The shipwreck was located 1,148 feet below the surface in waters between Italy and France. Two remotely operated vehicles (ROV) were used to scan the site and recover artifacts.

Short bursts of daily activity linked to reduced cancer risk - A total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers (i.e. cancers associated with physical activity such as liver, lung, kidney, gastric cardia (a type of stomach cancer), endometrial, myeloid leukemia, myeloma, colorectal, head and neck, bladder, breast and esophageal adenocarcinoma (cancer of the esophagus) by up to 32 percent.
