Sterilization is hands down one of the most important technologies ever developed by mankind, but though we've known how to do battle with bacterial pathogens in places like the operating room for decades, superbugs like MRSA and Clostridium difficile persist in hospital environments, often causing serious medical complications.
A new database developed by Spanish biologists is giving pharmaceutical quick access to protein structure data that could lead to more rapid development of important biologic drugs. The database, known as MoDEL, contains protein motion data for more than 1,700 different human proteins, making it the largest such database of proteins in the world.
Pills that only contain medicine are so very 20th century. Swiss pharma house Novartis thinks pills needn't merely deliver medicine to the bloodstream, but could also monitor its effects and transmit data to physicians. As such, the firm plans to bring a chip-in-a-pill technology before European regulators within 18 months that can both deliver drugs and transmit information from inside a patient's body to a patch worn on the patient's skin.
A new fuel-free propulsion system for nanodevices works like a disappearing act, dissolving an object at one end and re-generating it at the other end.
The method requires an electrical current to work, so it’s not completely energy-free, but it could be an effective way to propel nanoscale materials inside nano- or micro-devices. It could even lead to disappearing magical motors that vanish once their task is complete.
A blind Finnish man implanted with a special chip in his retina was able to see letters, a clock face and even different shades of gray, according to a new study. The device could represent a new form of vision therapy that relies on patients' own eyes, instead of cameras and synthetic eye components.
Any immunology textbook will tell you that once a virus enters a cell, the only way to knock that virus out is to kill the entire cell. But a new study from the Laboratory of Molecular Biology at Cambridge has shown a way to kill a virus from within the cell, leaving the virus defeated and the cell victorious and intact.
Research presented at Sunday's American Association for the Study of Liver Diseases in Boston marked a preliminary but potentially groundbreaking development in the search for the lab-engineered organs of the future. Scientists at the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center have engineered the first functioning miniature livers from human liver cells ever created in a lab setting.
Why swallow your vitamins when you can huff them? That's the general thinking behind the world's first breathable vitamin, called LeWhif Vitamin, which launched in the UK earlier this month and is expected to hit the US market this week.
The creation of Harvard biomedical engineer David Edwards, inventor of inhalable insulin, inhalable chocolate and inhalable coffee, LeWhif Vitamin is a lipstick-like delivery device that works a lot like a miniature pipe, only instead of inhaling smoke with each toke, you inhale a fine powder of healing supplements (a sort of anti-smoke) that dissolves in your mouth.
Just in time for the end of National Breast Cancer Awareness Month, a University of Manchester professor has developed a portable, radio frequency-based scanner that is able to show the presence of breast tumors, both malignant and benign, in real time.
High-risk patients can lose hours and thousands of dollars to in-hospital heart monitoring, but now physicians can regularly check in from afar. German cellphone maker H'andy's Sana 210 needs only 30 seconds to measure heart rhythm and send it to a doctor. When your heart moves, it sends electricity through your body; the Sana uses the same electric sensors as a hospital electrocardiogram (ECG) to record those pulses through your fingertips.
