How Moisturizers Work

Moisturizers, lotions, and even lip balms keep your skin smooth as the weather gets dry because they prevent water from migrating and evaporating out of your skin. This video from the American Chemical Society shows you exactly how they work. Read more...

Cutting food waste, but tossing more packaging: Our plastics conundrum

(American Chemical Society) These days, grocery stores contain aisle after aisle of products encased in plastic packaging. This practice preserves food and might help prevent food waste, but does the environmental cost justify it? The cover story of Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, looks into the matter.

The latest science on Zika and the challenges ahead

(American Chemical Society) As health officials around the world continue to fight the spread of Zika, scientists are working quickly to better understand the virus. A review article in the journal ACS Infectious Diseases summarizes what they now know -- or suspect -- about the disease, and what the remaining challenges are for its diagnosis, treatment and prevention.

Tiny gold particles could be the key to developing a treatment for pancreatic cancer

(American Chemical Society) A diagnosis of pancreatic cancer is often a death sentence because chemotherapy and radiation have little impact on the disease. In the US this year, some 53,000 new cases will be diagnosed, and 42,000 patients will die of the disease, according to the National Institutes of Health. Show More Summary

Biomass heating could get a 'green' boost with the help of fungi

(American Chemical Society) In colder weather, people have long been warming up around campfires and woodstoves. Lately, this idea of burning wood or other biomass for heat has surged in popularity as an alternative to using fossil fuels. Show More Summary

Shadows reveal how insects walk on water (video)

(American Chemical Society) Water striders' ability to walk and jump on the surfaces of ponds and lakes has long amazed curious observers -- and inspired robot designers who want to mimic the bugs' talent. Now, scientists have measured for the first time key parameters that allow them to walk on water -- by studying their leg shadows. Show More Summary

How do insects walk on water?

A new study illuminates this shadowy question. First, the video: And now, a press note from the American Chemical Society: Water striders’ ability to walk and jump on the surfaces of ponds and lakes has long amazed curious observers — and inspired robot designers who want to mimic the bugs’ talent. Now, scientists have measured…

New molecule may help fight obesity by converting 'bad' fat to 'good' fat

(Federation of American Societies for Experimental Biology) New research, published online in The FASEB Journal, suggests that activation of a chemical called ?-LGND2 by the estrogen receptor ? (ER- ?) reduces obesity and metabolic diseases in mice by converting bad fat (white fat) to good fat (brown fat). Show More Summary

Still wary of heparin from China, US considers options

(American Chemical Society) China's appetite for pigs fills dinner plates, but it also fills half the world's orders for heparin, an anticoagulant made from the animals' intestines. However in 2007 and 2008, adulterated supply from the country was linked to more than 80 deaths in the US. Show More Summary

How protein fragments associated with Alzheimer's could trigger Parkinson's

(American Chemical Society) Alzheimer's and Parkinson's diseases are different neurodegenerative conditions that can sometimes affect the same person, which has led scientists to investigate possible links between the two. Now one team,...Show More Summary

Salty snow could affect air pollution in the Arctic

(American Chemical Society) In pictures, the Arctic appears pristine and timeless with its barren lands and icy landscape. In reality, the area is rapidly changing. Scientists are working to understand the chemistry behind these changes to better predict what could happen to the region in the future. Show More Summary

Test improves detection of proteins in starch; aids in 'gluten-free' labeling

(American Chemical Society) For people with celiac disease, wheat allergies or gluten sensitivity, the options for gluten-free foods are growing. But knowing for sure whether products marketed as such are truly safe to eat can be more complicated than just reading a label. Show More Summary

The 'end of pain': How anesthesia works (video)

(American Chemical Society) Anesthesia now allows tens of thousands of patients every day to avoid the pain and memories of their procedures. But how does anesthesia work? This week, Reactions looks at scientists' current understanding of what happens when you go under. Watch the video here:

Shedding light on the limits of the expanded genetic code

(American Chemical Society) In 2014, scientists made a huge news splash when they reported the ability to grow bacteria with an expanded genetic code. Critics feared the rise of unnatural creatures; others appreciated the therapeutic potential of the development. Show More Summary

'Smart clothing' could someday power cell phones with the sun's rays

(American Chemical Society) Batteries in smart phones and other portable electronics often die at inopportune times. Carrying a spare battery is one solution. As an alternative, researchers have tried to create fibers to incorporate in clothing that would power these devices. Show More Summary

A nerve agent antidote that could be taken before an attack

(American Chemical Society) Nerve agents are molecular weapons that invade the body and sabotage part of the nervous system, causing horrific symptoms and sometimes death within minutes. Few antidotes exist, and those that do must be administered soon after an attack. Show More Summary
