A Boy And His Atom: The World's Smallest Movie

The ability to move single atoms—the smallest particles of any element in the universe—is crucial to IBM's research in the field of atomic memory. But even nanophysicists need to have a little fun. In that spirit, IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times.



  • Chikungunya Virus Contracted in U.S. for First Time

    While the mosquito-borne virus has spread throughout Central American and the Caribbean, it's only in southern U.S. states so far.

  • Is Fluoride in Drinking Water Safe?

    Fluoride is found in our tap water, toothpaste, and tea. It's helped fight cavities in children for decades. 70 years after Grand Rapids, Michigan, became the first city to fluoridate its drinking water, the practice remains controversial. Some still worry that fluoridated drinking water can lead to health issues. What is the scientific consensus? 

  • Paving Roads with Pig Manure

    A new replacement for petroleum is coming from an unlikely source, i.e., pig manure. It turns out that pig waste is particularly rich in oils that are very similar to petroleum. And while these oils are too low grade to produce gasoline, they may still work where the rubber meets the road.

  • Sparkler Chemistry

    Sparklers are a classic crowd-pleaser, and this video looks at the chemistry of these July 4th mainstays in super slow-motion.

  • Innate Lymphoid Cells

    Along with the skin, the gut mucosa represents the first line of defense against environmental factors. In the gut mucosa, a recently discovered type of lymphocytes called innate lymphoid cells (ILCs) maintain tissue homeostasis, orchestrate tolerance to food or commensal bacteria and contribute to immune responses to pathogens.

  • Hobbit Histories: The Origins of Homo Floresiensis

    The origins of the species known as “the hobbit,”  a human relative only a little over a meter tall, have been debated ever since its discovery in 2004. Now new fossils may reveal the ancestors of this strange species and help us to understand its history.

  • Why Do Onions Make You Cry?

    Common in cuisine all around the globe, onions are renowned for their ability to make us all look like crybabies. This American Chemical Society video gets to the bottom of this teary phenomenon and reveals exactly what chemical mechanisms trigger it. The video also features a few chemistry-backed tips you can try at home to stop the tears before they start.

  • Is There a Reproducibility Crisis in Science?

    Reproducibility is a hot topic in science at the moment, but is there a crisis? Nature asked 1,576 scientists this question as part of an online survey. Most agree that there is a crisis and over 70% said they'd tried and failed to reproduce another group's experiments.

  • Cancer Close-Up: Single-Cell Approach Provides Detailed Look Inside Tumors

    Members of the Klarman Cell Observatory at the Broad Institute and the Joint Center for Cancer Precision Medicine (CCPM) at the Dana-Farber Cancer Institute, Brigham and Women’s Hospital, and the Broad have embarked on an effort to use single-cell genome analysis to explore the diverse cellular environments of cancer tumors in finer detail than ever before. In this video, researchers involved in a pilot study that looked at melanoma – the most deadly form of skin cancer -- describe their methods, their findings, and their hopes for how their approach might inform patient care in the years to come.

  • Does Homeopathy Work?

    The use of homeopathic remedies have gone on for nearly 200 years, but so has the progress of science. And that progress has shown us that the foundations of homeopathy are bunk.

Scientifically Studying Ecstasy

MDMA (commonly known as the empathogen “ecstasy”) is classified as a Schedule 1 drug, which is reserved for compounds with no accepted medical use and a high abuse potential. Two researchers from Stanford, however, call for a rigorous scientific exploration of MDMA's effects to identify precisely how the drug works, the data from which could be used to develop therapeutic compounds.

Do you agree that ecstasy should be studied for its potential therapeutic benefits?
