(PhysOrg.com) -- "Scientists have been interested in generating and observing macroscopic quantum superpositions in order to test quantum mechanics at the macroscopic scale," physicist Hyunseok Jeong of Seoul National University in Seoul, South Korea, told PhysOrg.com. "There have been many papers in which the authors claim to have generated mesoscopic or macroscopic superpositions, often called 'Schrodinger cat states.' However, quoting A

Cosmic neutrinos could yield key insights, but detection devices would need to be the size of a star or galaxy In "Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated. For instance, they might involve machines beyond the realm of possibility, such as particle accelerators as big as the sun, or they might be completely unethical, such as lethal experiments involving people. This feature aims to look at the impossible dreams, the seemingly intractable problems in science

Mark Peter Davis, co-founder of Kohort, a social media start-up in New York, discusses the best way an entrepreneur can face the moment he asks this question. We entrepreneurs are told to listen to feedback, but ignore the naysayers.

Last week, the Foundation Questions Institute announced the winners of its third essay contest , which Scientific American co-sponsored. (I helped to decide on the question, judge the essays and hand out the awards at the World Science Festival in New York City.) The essay question was, "Is Reality Digital or Analog?" Is nature, at root, continuous or discretized

A joke among researchers in the field of male contraception is that a clinically approved alternative to condoms or vasectomy has been five to 10 years away for the past 40 years.

Last Saturday, at a workshop organized by the Foundation Questions Institute , Nobel laureate physicist Gerard 't Hooft gave a few informal remarks on the deep nature of reality.

(PhysOrg.com) -- The quick mixing of coffee and milk after stirring or the formation of raindrops in clouds: these are just two of many phenomena in which turbulent flows play a decisive role.

When Omega Eggs (eggs containing Omega fatty acids) first appeared on the mass market in the early 2000s I had this bizarre image in my head of a semi-crazed scientist extracting the yolk with a giant syringe, swirling it about in a beaker with a neon blue solution to extract the bad fat, injecting it with Omega fatty acids and then placing it carefully back inside the eggshell.

Experiment Might Take Thousands of Volunteers and Decades of Effort In "Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated. For instance, they might involve machines beyond the realm of possibility, such as particle accelerators as big as the sun, or they might be completely unethical, such as lethal experiments involving people.

We spend a third of our lives asleep.

Attempting to fix our planet might be easier than adapting to an uncertain future In "Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated.

The topic of "life after death" raises disreputable connotations of past-life regression and haunted houses, but there are a large number of people in the world who believe in some form of persistence of the individual soul after life ends. Clearly this is an important question, one of the most important ones we can possibly think of in terms of relevance to human life. If science has something to say about, we should all be interested in hearing

A week's warning could save an untold number of lives In ""Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated. For instance, they might involve machines beyond the realm of possibility, such as particle accelerators as big as the sun, or they might be completely unethical, such as lethal experiments involving people.

What does the scientist who talked about enclosing stars with globes think might be too hard for science? In "Too Hard for Science?" I interview scientists about ideas they would love to explore that they don't think could be investigated. For instance, they might involve machines beyond the realm of possibility, such as particle accelerators as big as the sun, or they might be completely unethical, such as lethal experiments involving people.
