Alarming Study Finds Dangerous Chemicals in Most "Non-Toxic" and "BPA-Free" Teethers

In a troubling new study, research shows that many teethers aren't as safe for babies - despite their labeling - as parents believe. The results, published in the American Chemical Society's journal Environmental Science and Technology,...Show More Summary

Shaping pharma: The industry's top stories from 2016

(American Chemical Society) As the year comes to an end, Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, takes stock of the top 10 stories that shaped the pharmaceutical landscape and set the stage for 2017.

Could a seawater battery help end our dependence on lithium?

(American Chemical Society) With the ubiquity of lithium-ion batteries in smartphones and other rechargeable devices, it's hard to imagine replacing them. But the rising price of lithium has spurred a search for alternatives. One up-and-coming battery technology uses abundant, readily available seawater. Show More Summary

MAO is a possible Alzheimer's disease biomarker

(American Chemical Society) Alzheimer's disease affects more than 35 million people, a number that is expected to increase in the coming years. Currently, Alzheimer's diagnoses rely on clinical neuropathologic assessment of amyloid-? peptide aggregates (plaques) and neurofibrillary tangles. Show More Summary

Baby teethers soothe, but many contain low levels of BPA

(American Chemical Society) Bisphenol-A (BPA), parabens and antimicrobials are widely used in personal care products and plastics. The US and other governments have banned or restricted some of these compounds' use in certain products for babies and kids. Show More Summary

Mimicking bug eyes could brighten reflective signs and clothes

(American Chemical Society) That bright, reflective coating used on road signs, bicycles and clothing are important safety measures at night. They help drivers get to their destinations while avoiding bicyclists and pedestrians in low-light conditions. Show More Summary

Can I still eat this? (video)

(American Chemical Society) An estimated 133 billion pounds of food gets thrown out every year in the United States, so understanding when your food goes bad is important to help reduce waste. This week, Reactions talks food expiration-date...Show More Summary

Did comets kick-start life on Earth? (video)

(American Chemical Society) The origins of life on Earth are still shrouded in mystery. One compelling possibility is that comets delivered the building blocks for life eons ago. This week, Speaking of Chemistry explains the chemistry behind how these icy, lumpy space rocks might have seeded life on Earth. Check out the video here: https://youtu.be/FnuldVd99x8.

When turkeys explode (video)

(American Chemical Society) The thousands of 'turkey-fryer explosion' videos on YouTube are a testament to why frozen turkeys and hot oil are an especially dangerous mix. With the holiday coming up, Reactions teamed up with the District...Show More Summary

Storing carbon dioxide underground by turning it into rock

(American Chemical Society) In November, the Paris Climate Agreement goes into effect to reduce global carbon emissions. To achieve the set targets, experts say capturing and storing carbon must be part of the solution. Several projects throughout the world are trying to make that happen. Show More Summary

Controversial drug approval stirs deep concerns -- and hope

(American Chemical Society) In September, the Food and Drug Administration approved Exondys, a controversial treatment for Duchenne muscular dystrophy based on tenuous data from just 12 patients. The cover story in Chemical & Engineering...Show More Summary

Solar smart window could offer privacy and light control on demand (video)

(American Chemical Society) Smart windows get darker to filter out the sun's rays on bright days, and turn clear on cloudy days to let more light in. This feature can help control indoor temperatures and offers some privacy without resorting to aids such as mini-blinds. Show More Summary

How to stop acne with science (video)

(American Chemical Society) Breakouts are a pain and can happen well into your 40s. While there's no cure to make acne instantly go away, there are a few science-backed tips you can use to help minimize the number of pimples that pop up. Show More Summary

Mirroring a drop in emissions, mercury in tuna also declines

(American Chemical Society) For years, public health experts have warned against eating certain kinds of fish, including tuna, that tend to accumulate mercury. Still, tuna consumption provides more mercury to US consumers than any other source. Show More Summary

How bacteria make it rain (video)

(American Chemical Society) The oceans are covered with a thin film of organic matter and bacteria, many of which launch out of the water and go airborne. But these little particles do more than just take flight -- these microbes can actually make it rain. Show More Summary

Making artificial 'cells' move like real cells (video)

(American Chemical Society) Artificial 'cells' could someday zoom around in the body and deliver medicines to specific locations, act as in-tissue diagnosticians and provide viable replacements for whole cells and organs. To do this, they will need to be able to navigate the complex environments of our bodies. Show More Summary

Quantifying the hidden environmental cost of hydroelectric dams

(American Chemical Society) Hydroelectricity is a renewable energy, and the facilities that produce it give off less greenhouse gases than other power plants. But damming bodies of water can lead to the production and release of methylmercury from the soil. Show More Summary

Marathon chemistry: The science of distance running (video)

(American Chemical Society) Marathons are tough. Athletes push their bodies for miles and deal with cramping, dehydration and every runner's worst fear: that extreme form of fatigue called 'hitting the wall.' Why is distance runningShow More Summary

Start-ups use chemistry to tackle challenges from roll-up TVs to neglected diseases

(American Chemical Society) The term 'start-up' can bring to mind thoughts of economic bubbles and busts. But out of many company starts, a few will go on to succeed and even flourish. For the second year, Chemical & Engineering News,...Show More Summary

Rewritable material could help reduce paper waste

(American Chemical Society) Even in today's digital age, the world still relies on paper and ink, most of which ends up in landfills or recycling centers.
