In the 1942 short story "Runaround", author Isaac Asimov came up with Three Laws of Robotics and those fictional ethics have captivated engineers ever since.

Maintaining the spirit of Asimov, Dr. Eduardo Morales Manzanares of the National Institute of Astrophysics, Optics and Electronics (INAOE) in Mexico has developed robots with artificial intelligence that don’t require specialized personnel to be controlled.

Instead, software allows the robot named Sabina to be able to learn with the guide of the user, either through a remote control or through voice commands or simply by showing the automaton tasks, as one would teach a toddler. That means anyone can program it without being an expert in robotics

The most probable date for Good Friday is April 3, 33 AD. This date is due to Isaac Newton.

Easter is that holiday that wanders around in the calendar and which you never quite know when will take place. Some get annoyed by that, but frankly I find it charming. But when did the crucifixion of Jesus really take place?

Questions like these were of much concern to Isaac Newton (1642-1726), surprisingly, since he is best known for gravitation and planetary orbits.

Modern technology for healing distal femur fractures is as safe and effective as its more established alternative, but without the potential shortfall of the older approach.

A new study found that when done correctly, there are no significant differences between "locked plating" and "non-locked plating" in terms of healing rates, need for corrective surgery, or hardware failure.

The number of total hip replacements (THRs) nearly doubled among middle-aged patients between 2002-2011, primarily due to the expansion of the middle-aged population in the U.S., according to a new study presented today at the 2015 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). Continued growth in utilization of hip replacement surgery in patients age 45 to 64, an increase in revision surgeries for this population as they age, and a nearly 30 percent decline in the number of surgeons who perform THR, could have significant implications for future health care costs, THR demand and access.

As the world looks to American innovation to fight Ebola, malaria, tuberculosis, and a host of other health threats, a new report released today on Capitol Hill warns budget battles in Washington are eroding preparedness at home and abroad at a time when scientific advances are poised to deliver new lifesaving drugs, vaccines, and diagnostics.

Young adolescents' judgements on how risky a situation might be are most influenced by what other teenagers think, while most other age groups are more influenced by adults' views, finds a new survey by psychologists.

BioBlast Pharma Ltd. has announced positive preclinical in vitro and in vivo proof-of-concept study results for its mitochondrial protein replacement therapy drug candidate (BB-FA) for Friedreich's Ataxia.

Friedreich's Ataxia is an inherited disorder characterized by progressive deterioration of the muscular and nervous system that begins in the first or second decade of life and results in gait disturbance (ataxia), cognitive impairment, progressive heart disease and diabetes. According to Friedreich's Ataxia Research Alliance (FARA), about 1:50,000 people in the U.S. suffer from Friedreich's Ataxia. Most patients are wheelchair-bound within 15 years of diagnosis.

Antioxidants provide long-term protection against the chain reactions of free radical processes, in other words, of the molecules that are capable of causing cell damage and generating various diseases. Free radicals harm our body by causing, in the best of cases, ageing and, in the worse, serious diseases. Lettuce is rich in antioxidants, as it contains compounds like phenolic acids, flavonoids, anthocyanins, and vitamins A and C, among other things.

Reclusive giant pandas fascinate the world, yet precious little is known about how they spend their time in the Chinese bamboo forests. Until now.

A team of Michigan State University (MSU) researchers who have been electronically stalking five pandas in the wild, courtesy of rare GPS collars, have finished crunching months of data and has published some panda surprises in this month's Journal of Mammalogy.

Traditionally, to understand how a gene functions, a scientist would breed an organism that lacks that gene - "knocking it out" - then ask how the organism has changed. Are its senses affected? Its behavior? Can it even survive? Thanks to the recent advance of gene editing technology, this gold standard genetic experiment has become much more accessible in a wide variety of organisms. Now, researchers at Rockefeller University have harnessed a technique known as CRISPR-Cas9 editing in an important and understudied species: the mosquito, Aedes aegypti, which infects hundreds of millions of people annually with the deadly diseases chikungunya, yellow fever, and dengue fever.
