A high-tech screening tool for cervical cancer is facing pushback from more than a dozen patient groups, who warn that the genetic test could displace a simpler, cheaper and more established mainstay of women's health: the Pap smear.
The debate over salt intake has filled the pages of health magazines and newspapers for years....
Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting...
In a feat of reverse tissue engineering, researchers have begun to unravel the complex genetic coding that allows embryonic cells to proliferate and transform into all of the specialized cells that perform a myriad of different biological tasks.
Scientists have unearthed still more evidence that antibiotics can contribute to obesity. New research suggests that patients on long-term antibiotic treatment gained weight and had significant changes in their gut microbiota.
Researchers coaxed human embryonic stem cells to turn into working spinal cord cells more efficiently by growing the cells on a soft, ultrafine carpet made of a key ingredient in Silly Putty.
Treatment options for the 170 million people worldwide with chronic Hepatitis C virus are evolving rapidly, although the available regimens often come with significant side effects. Two multi-center clinical trials show promise for a new option that could help lead to an increase in patients cured with a much more simple and tolerable all-oral therapy.
Research may turn an enzyme that acts as a specialized “wrench” in antibiotic assembly into a set of wrenches that will allow for greater customization. By modifying this enzyme, scientists hope to be able to design and synthesize stronger, more adaptable antibiotics from less expensive, natural compounds.
In an attempt to understand exactly what happens in the brain of schizophrenic people, researchers have analyzed proteins in the brains of rats that have been given hallucinogenic drugs. This may pave the way for new and better medicines.
A new psychology study using mice provides evidence that being overweight makes people tired and sedentary— not the other way around.
Not many people achieve the recommendation of five portions of fruits and vegetables per day – the current average intake is just under four. But, the reduced risk of dying from cancer and heart disease is associated with any increased intake of vegetables and fruit over and above one portion per day. So the more you eat, the more you reduce your risk.
T-cells use a complex process to recognize foreign pathogens and diseased cells. Researchers have added a new level of understanding to that process by describing how the T-cell receptors use mechanical contact– the forces involved in their binding to the antigens– to make decisions about whether or not the cells they encounter are threats.
A study has revealed that a drug that inhibits a molecule called prostaglandin E2 increases survival rates in mice infected with a lethal dose of the H1N1 flu virus.
A pH-sensitive microchip, invented by chemists, could improve postoperative care for patients with knee replacements and other surgical implants.
According to EU guidelines, the new compound R1234yf should, in the future, be used as the refrigerant in air-conditioning systems for automobiles. But the compound is inflammable, and chemists have shown that combustion of the cooling agent leads to the formation of the highly toxic carbonyl fluoride.
A fast diagnosis and treatment can mean the difference between life and death for stroke victims. So scientists are working on a new blood test that one day could rapidly confirm whether someone is having a stroke and what kind.
A team of researchers has transformed Google Glass into a powerful, wearable medical testing laboratory. They developed an application that reads dozens of different types of diagnostic tests for malaria, prostate cancer and HIV, to name a few.
Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer.
In the fight against “superbugs,” scientists have discovered a class of agents that can make some of the most notorious strains vulnerable to the same antibiotics that they once handily shrugged off.
Synthetic genetic circuitry is helping researchers see, for the first time, how to regulate cell mechanisms that degrade the misfolded proteins implicated in Parkinson’s, Huntington’s and other diseases.
Researchers have developed the first wearable patch that can monitor your health, store and transmit data and deliver drugs when needed. Such a device has instant applications for those suffering from diabetes or heart diseases.
A team of scientists has succeeded in regenerating a living organ for the first time. They rebuilt the thymus— an organ in the body located next to the heart that produces important immune cells.
A new study is providing insights into why alcohol has such a negative effect on wound healing. Researchers report that binge alcohol exposure significantly reduced levels of key components of the immune system involved in healing.
Subpopulations of breast cancer cells sometimes cooperate to aid tumor growth, according to researchers, who believe that understanding the relationship between cancer subpopulations could lead to new targets for cancer treatment.
In a north London hospital, scientists are growing noses, ears and blood vessels in a bold attempt to make body parts using stem cells. While only a handful of patients have received the British lab-made organs so far, researchers hope they will soon be able to transplant more types of body parts into patients, including what would be the world's first nose made partly from stem cells.
Three years ago, doctors reported that zapping a paralyzed man's spinal cord with electricity allowed him to stand and move his legs. Now, they've done the same with three other patients, suggesting their original success was no fluke.
Scientists have, for the first time, demonstrated that caffeine has a positive effect on tau deposits in Alzheimer's disease. Because of the study, a new class of drugs may be developed for the treatment of the disease.
