For decades, neuroscientists have been trying to design computer networks that can mimic visual skills such as recognizing objects. Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. However, a new study from MIT neuroscientists has found that one of the latest generation of these so-called “deep neural networks” matches the primate brain.

Using a computer algorithm that can sift through mounds of genetic data, researchers from Brown University have identified several networks of genes that, when hit by a mutation, could play a role in the development of multiple types of cancer. The algorithm, called Hotnet2, was used to analyze genetic data from 12 different types of cancer assembled as part of the pan-cancer project of The Cancer Genome Atlas (TCGA).
MS affects more than two million people worldwide. Symptoms are different for everyone but commonly include fatigue, tingling, speech problems and difficulties with walking and balance. To gain a better understanding of MS and its treatments, there is a need for a system to collect comprehensive data that provides an in-depth picture of the experiences of MS patients across a large population.

Geckos have fascinated people for hundreds of years. Scientists have been especially intrigued by these lizards, and have studied a variety of features such as the adhesive toe pads on the underside of gecko feet with which geckos attach to surfaces with remarkable strength. One question that has captivated researchers is: Is the strength of this adhesion determined by the gecko or is it somehow intrinsic to the adhesive system?
Researchers have made great progress in recent years in the design and creation of biological circuits — systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But, while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined.
At a White House ceremony on November 20, 2014, President Obama presented the National Medal of Science and National Medal of Technology and Innovation to individuals who have made outstanding contributions to science and engineering. The awards are the nation's highest honors for achievement and leadership in advancing the fields of science and technology.
Conventional treatment seeks to eradicate cancer cells by drugs and therapy delivered from outside the cell, which may also affect — and potentially harm — nearby normal cells. In contrast, a research team has developed several novel designs for iron-oxide based nanoparticles that detect, diagnose and destroy cancer cells using photo-thermal therapy, using nanoparticles to focus light-induced heat energy only within the tumor

Botanists have launched a database with information that documents significant ‘life events’ for nearly 600 plant species across the globe. They clubbed together with like-minded individuals working across five different continents to compile the huge database of plant life histories, for which data have been gathered over a near 50-year span.
Symbion QT 2.5. chemometrics software provides Parametric Data Cleaning, a technique that automates the handling of data compromised by excessive noise or other artifacts. Key cleaning parameters are under the control of the analyst, allowing chemometric optimization under a wide range of analytical situations.
Sinclair suggests that there still is a place in science in modern times for the interpretation of results using rational numbers or simple ratios. In a time where supercomputers dominate analysis, he argues that there is not enough attention being paid to the basic approaches to science of the past, which were able to profoundly illuminate our understanding of the natural world through the simplification of very complex topics and systems.
How does a normal cellular process derail and become unhealthy? A multi-institutional, international team led by Virginia Tech researchers studied cells found in breast and other types of connective tissue and discovered new information about cell transitions that take place during wound healing and cancer.
A team of computer scientists working to improve how researchers across the sciences empower big data to solve problems have been awarded $5 million by the National Science Foundation. The team will address one of the leading challenges in tackling some of the world’s most pressing issues in science: the ability to analyze and compute large amounts of data.
New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.
Bio-engineers are working on the development of biological computers with the aim of designing small circuits made from biological material that can be integrated into cells to change their functions. In the future, such developments could enable cancer cells to be reprogrammed, thereby preventing them from dividing at an uncontrollable rate. Stem cells could likewise be reprogrammed into differentiated organ cells.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics — a breakthrough that will help develop drugs which can effectively tackle infections in the future. Researchers at the University of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it from working, making the bacteria resistant.
