Pioneering gene therapy has restored some vision to patients with a rare form of genetic blindness for as long as four years, raising hopes it could be used to cure common causes of vision loss, new research shows.
A new epoch-making discovery has been made, which may prove decisive to future brain research. The level of salts in the brain plays a critical role in whether we are asleep or awake. This discovery may be of great importance to research on psychiatric diseases such as schizophrenia and convulsive fits from lack of sleep as well as post-anaesthetization confusion, according to experts.
Seen as antithetical to one another, evolution and religion can hardly fit in a scientific discourse simultaneously. One expert has observed the influences a few major religions have had on evolutionists and their scientific thinking. Inspired by the lack of pigmentation and/or eyes in some cave organisms, he focuses on biospeleology to challenge the notions of predetermination and linearity.
Flight is one of nature's greatest breakthroughs. It enables escape, dispersion, and exploration. Lacking flight keeps you grounded -- sometimes for a long time even from evolution's perspective. The Madrona Marsh Preserve is a small nature preserve in one of the world's largest metropolitan areas, which has withstood decades of farming, oil exploration, and development pressures. Surprisingly, a treasure of flightless animals survived.
Strokes, seizures, traumatic brain injury and schizophrenia: these conditions can cause persistent, widespread acidity around neurons in the brain. But exactly how that acidity affects brain function isn't well understood.
Astronomers have found a unique object that appears to be made of inner solar system material from the time of Earth's formation, billions of years ago. Observations show that C/2014 S3 (PANSTARRS) is the first object to be discovered on a long-period cometary orbit that has the characteristics of a pristine inner solar system asteroid. It may help understanding how the solar system formed.
Assistive technology -- the use of (frequently modified or customized) equipment to improve the functional capabilities of people with special needs -- is an important therapeutic tool. A new study finds that household utensils modified in relatively simple and cheap ways can increase autonomy and self-esteem and positively impact the quality of life of patients with leprosy.
With an ever-increasing volume of electronic data being collected by the healthcare system, researchers are exploring the use of machine learning -- a subfield of artificial intelligence -- to improve medical care and patient outcomes.
For women who have undergone mastectomy for breast cancer, breast reconstruction using the abdominal 'DIEP flap' provides good long-term quality of life (QOL) -- similar to that of women without breast cancer.
Researchers have demonstrated a cheap, effective and environmentally friendly way to sterilize medical implants without changing their properties, in contrast to some techniques. This inexpensive technology could save time and money while effectively sterilizing medical implants, does not require extensive training and produces no waste products.
In order to avoid spam, on many websites users are prompted to prove that they are human by entering symbols that are difficult to read. For partially sighted users, acoustic solutions have been devised. IT researchers intend to improve their quality.
Medical researchers have obtained a breakthrough in identifying genes that increase the chance for mothers to have dizygotic twins. Researchers believe the findings represent a significant advance in the identification of key mechanisms controlling ovarian function and provide a greater understanding of female fertility and infertility.
Hepatitis C virus hijacks the host's fat metabolism for its own survival, growth, and transport in the human body. A study identifies a host gene involved in the formation of HCV virus particles and helps explain why humans with a rare mutation in the gene have problems with their fat metabolism.
Ebola and other dangerous microbes often produce these inflammatory responses. Researchers say that tiny doses of a cancer drug may stop the raging, uncontrollable immune response to infection that leads to sepsis and kills up to 500,000 people a year in the US. The new drug treatment may also benefit millions of people worldwide who are affected by infections and pandemics.
Centuries before modern countries such as Dubai and China started building islands, native peoples in southwest Florida known as the Calusa were piling shells into massive heaps to construct their own water-bound towns.
Scientists have shown how spin-polarized currents can be initiated in a controlled manner within samples of topological insulator material. In addition, they were able to manipulate the orientation of the spins of these currents.
