Of the importance of giving opportunities to practice

by Mirjam Sophia Glessmer in Adventures in Teaching and Oceanography

When you are short on time and want to teach as much as possible in a given time, how do you allocate time to different activities and are there any that you might be able to drop? Classically, practice is … Continue reading →... Read more »

The “Invisible Web” Undermines Health Information Privacy

by Jalees Rehman in The Next Regeneration

What do the third parties do with your data? We do not really know because the laws and regulations are rather fuzzy here. We do know that Google, Facebook and Twitter primarily make money by advertising so they could potentially use your info and customize the ads you see. Just because you visited a page on breast cancer does not mean that the "Invisible Web" knows your name and address but they do know that you have some interest in breast cancer. It would make financial sense to sen........ Read more »

How do you make sure your students come prepared to your flipped course?

by Mirjam Sophia Glessmer in Adventures in Teaching and Oceanography

As I mentioned a while back, we are preparing a flipped course. And the biggest question always is how to make sure students actually prepare for class. Because if they weren’t prepared, what would you do? Repeat the content they … Continue reading →... Read more »

Drawing a line between quantum and classical world

by Dr. Jekyll in Lunatic Laboratories

Quantum theory is one of the great achievements of 20th century science, yet physicists have struggled to find a clear boundary between our everyday world and what Albert Einstein called the “spooky” features of the quantum world, including cats that could be both alive and dead, and photons that can communicate with each other across space instantaneously....

Dead galaxies in Coma Cluster may be packed with dark matter

by Dr. Jekyll in Lunatic Laboratories

Galaxies in a cluster roughly 300 million light years from Earth could contain as much as 100 times more dark matter than visible matter, according to an Australian study. The research, published today, used powerful computer simulations to study galaxies that have fallen into the Coma Cluster, one of the largest structures in the Universe in which thousands of galaxies are bound together by gravity....

Study finds metal foams capable of shielding X-rays, gamma rays, neutron radiation

by Dr. Jekyll in Lunatic Laboratories

Research from North Carolina State University shows that lightweight composite metal foams are effective at blocking X-rays, gamma rays and neutron radiation, and are capable of absorbing the energy of high impact collisions. The finding means the metal foams hold promise for use in nuclear safety, space exploration and medical technology applications.... Read more »

A new wrinkle: Geometry of brain’s outer surface correlates with genetic heritage

by Dr. Jekyll in Lunatic Laboratories

Researchers at the University of California, San Diego and the School of Medicine have found that the three-dimensional shape of the cerebral cortex – the wrinkled outer layer of the brain controlling many functions of thinking and sensation – strongly correlates with ancestral background. The study opens the door to more precise studies of brain anatomy going forward and could eventually lead to more personalized medicine approaches for diagnosing and treating brain diseases....

Freezing single atoms to absolute zero with microwaves brings quantum technology closer

by Dr. Jekyll in Lunatic Laboratories

Physicists at the University of Sussex have found a way of using everyday technology found in kitchen microwaves and mobile telephones to bring quantum physics closer to helping solve enormous scientific problems that the most powerful of today’s supercomputers cannot even begin to embark upon....

The fear you experience playing video games is real, and you enjoy it

by Dr. Jekyll in Lunatic Laboratories

With the advent of video games, a frequently asked question has been whether we get as engrossed in them emotionally as we do when we see a scary movie. The answer is yes and many game players enjoy the fear caused by the zombies, disfigured humans and darkness they often encounter, the researchers found.... Read more »

Synthetic biology used to engineer new route to biochemicals

by Dr. Jekyll in Lunatic Laboratories

Living cells can make a vast range of products for us, but they don’t always do it in the most straightforward or efficient way. Shota Atsumi, a chemistry professor at UC Davis, aims to address that through “synthetic biology:” designing and building new biochemical pathways within living cells, based on existing pathways from other living things....

Commenters exposed to prejudiced comments more likely to display prejudice themselves

by Dr. Jekyll in Lunatic Laboratories

Comment sections on websites continue to be an environment for trolls to spew racist opinions. The impact of these hateful words shouldn’t have an impact on how one views the news or others, but that may not be the case. A recent study found exposure to prejudiced online comments can increase people’s own prejudice, and increase the likelihood that they leave prejudiced comments themselves.... Read more »

What your clothes may say about you

by Dr. Jekyll in Lunatic Laboratories

Moving closer to the possibility of “materials that compute” and wearing your computer on your sleeve, researchers at the University of Pittsburgh Swanson School of Engineering have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs. The material system is sufficiently small and flexible that it could ultimately be integrated in........ Read more »

The New Way to Track Animals Is Tagless

by Elizabeth Preston in Inkfish



There's good news for scientists who study animals that are too small to carry a GPS monitor, or that spit ID tags back out through their arms. A setup using an off-the-shelf camera can precisely capture an animal's path in three dimensions—without anyone touching the animal.

Emmanuel de Margerie, who studies animal behavior at the University of Rennes 1 in France, says there are several reasons to seek new animal-tracking technologies. To put a GPS or other kind of tag on an animal, yo........ Read more »

The Future of Depression Treatment

by The Neurocritic in The Neurocritic

2014Jessica is depressed again. After six straight weeks of overtime, her boss blandly praised her teamwork at the product launch party. And the following week she was passed over for a promotion in favor of Jason, her junior co-worker. "It's always that way, I'll never get ahead..." She arrives at her therapist's office late, looking stressed, disheveled, and dejected. The same old feelings of worthlessness and despair prompted her to resume her medication and CBT routine."You deserve to be rec........ Read more »

First functional, synthetic immune organ with controllable antibodies created by engineers

Echoborgs: Psychologists Bring You Face To Face With A Chat-bot

by Neuroskeptic in Neuroskeptic_Discover

Last year I blogged about the creepy phenomenon of cyranoids. A cyranoid is a person who speaks the words of another person. With the help of a hidden earpiece, a 'source' whispers words into the ear of a 'shadower' , who repeats them. In research published last year, British psychologists Kevin Corti and Alex Gillespie showed that cyranoids are hard to spot: if you were speaking to one, you probably wouldn't know it, even if the source was an adult and the shadower a child, or vice versa.

Tiny grains of lithium dramatically improve performance of fusion plasma

by Dr. Jekyll in Lunatic Laboratories

While fusion might still be a far off dream, a new discovery may help bring that dream closer to reality. Scientists have discovered a phenomenon that helps them to improve fusion plasmas, a finding that could quicken the development of large scale fusion energy. The scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically....

When did we start using information theory in neuroscience?
