New brain implants disguise as neurons, offering a potentially safer way to study and treat the brain

Like a well-guarded fortress, the human brain attacks intruders on sight. Foreign objects, including neural probes used to study and treat the brain, do not last long. But now, researchers have designed a probe that looks, acts, and feels so much like a real neuron that the brain cannot identify the imposters. According to Charles M. Lieber, this breakthrough "literally blurs the ever-present and clear dissimilarities in properties between man-made and living systems." They have blurred the line between human and machine.

Unprecedented biological changes in the global ocean

Current monitoring of marine biological systems only covers a tiny fraction of the ocean, which limits scientists' ability to confidently predict the expected effects of climate disturbances on marine biodiversity. Using a new computer model, an international team led by the CNRS and involving researchers from Sorbonne University has demonstrated that biological changes are accelerating, which has consequences for our use of marine resources. Their findings are published in Nature Climate Change.

Online shopping algorithms are colluding to keep prices high

Have you ever searched for a product online in the morning and gone back to look at it again in the evening only to find the price has changed? In which case you may have been subject to the retailer's pricing algorithm.

Recognizing disease using less data

As artificial intelligence systems learn to better recognize and classify images, they are becoming highly-reliable at diagnosing diseases, such as skin cancer, from medical images. But as good as they are at detecting patterns, AI won't be replacing your doctor any time soon. Even when used as a tool, image recognition systems still require an expert to label the data, and a lot of data at that: it needs images of both healthy patients and sick patients. The algorithm finds patterns in the training data and when it receives new data, it uses what it has learned to identify the new image.

Spring migration is now earlier in European and North American birds

According to a new study, migratory birds in Europe and Canada have substantially advanced the timing of their spring migration due to climate change. The average migratory bird has advanced its spring migration by approximately one week in five decades, and the duration of the migration season has increased.

Researchers look to computing's past to unlock 3-D-printed mechanical logic gates for the future

Taking a page from the past, Lawrence Livermore National Laboratory scientists and engineers are combining mechanical computing with 3-D printing as part of an effort to create "sentient" materials that can respond to changes in their surroundings, even in extreme environments that would destroy electronic components, such as high radiation, heat or pressure.

Ground-breaking electric Chevrolet Volt runs out of juice

As their company was swirling around the financial drain in the early 2000s, General Motors executives came up with an idea to counter its gas-guzzling image and point the way to transportation of the future: an electric car with a gas-engine backup that could travel anywhere.

Researcher models the key transformations that emissions undergo in the atmosphere

Josh Moss is a Ph.D. student in the lab of Professor Jesse Kroll, where he studies atmospheric chemistry and examines the chemistry of gases and particles in the atmosphere that humans are releasing and their interactions with existing particles in the atmosphere. He focuses on organic chemical reactions that occur in the atmosphere which contribute significantly to smog formation. In the laboratory, he uses a controlled atmospheric chamber to conduct physical experiments on the gas phase reactions that originate from smog particles. Moss also works on computer models for chemical reaction generation and predictions. His research is concerned with chemicals commonly found in large urban cities such as Los Angeles, Houston, and Mexico City, and he is interested in the implications that these micro-particles have on human health and climate change.

Researchers use computer vision to better understand optical illusions

Optical illusions, images that deceive the human eye, are a fascinating research topic, as studying them can provide valuable insight into human cognition and perception. Researchers at Flinders University, in Australia, have recently carried out a very interesting study using a computer vision model to predict the existence of optical illusions and the degree of their effect.
