Researchers have mapped out how hundreds of mutations involved in two types of cancer affect the activity of proteins that are the ultimate actors behind the disease. The work points the way to identifying new precision treatments that may avoid the side effects common with much current chemotherapy.

Researchers have designed new antibodies that might provide more effective treatment methods for Alzheimer's disease. By designing antibodies that bind even to the smaller aggregates, or clumps, of the amyloid-beta protein, it may be possible to check the progress of the disease.

In geographic atrophy, a late form of age-related macular degeneration (AMD), reading ability is closely related to the altered retinal structure. Reading speed makes everyday functional impairment measurable, which the most common functional test in ophthalmology -- the best-corrected visual acuity assessment - cannot reflect. Retinal imaging can be used to assess loss of reading ability even when central visual acuity is still good.

A team of bioengineers has invented a novel soft and flexible self-powered bioelectronic device. The technology converts human body motions -- from bending an elbow to subtle movements such as a pulse on one's wrist -- into electricity that could be used to power wearable and implantable diagnostic sensors.

Despite smoking's well-known role in causing lung cancer, a significant number of patients who develop lung tumors have never smoked. While scientists are still working to understand what spurs cancer in so-called 'never-smokers,' a study suggests that 78% to 92% of lung cancers in patients who have never smoked can be treated with precision drugs already approved by the Food and Drug Administration to target specific mutations in a patient's tumor.

Opioid receptors play key roles in regulating our senses and emotions. Recently, their discovery outside the nervous system raised several questions about the effects of opioids on the immune system. Now, researchers have shown that KNT-127 -- a drug that targets delta opioid receptors -- can reduce pro-inflammatory signals in the colon. Their research highlights the immunomodulatory properties of opioids and indicates their therapeutic potential in inflammatory bowel disease and other related disorders.

A new study on foot-and-mouth disease among buffalo in South Africa could help explain how certain extremely contagious pathogens are able to persist and reach endemic stage in a population, long after they've burned through their initial pool of susceptible hosts.

A study found that pregnancy intentions often change over as short as a 12-month time period, and that they specifically vary with partner status, household income, and employment status.

Nerve cells (neurons) send signals throughout the brain and the body along long processes called axons; these communication and information processes consume high levels of energy. A recent study shows that the support cells around axons provide a way to boost local energy production. The new findings help explain how long axons maintain sufficient energy levels and could have implications for the treatment of several neurological disorders, including Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis (ALS), linked to disruptions in axonal energy supply.

Using the relatively simple clocks found in fruit flies, researchers reveal that the subcellular location of clock proteins and genes fluctuates with the daily passage of time, indicating that spatial information is translated into time-related signals.

What makes pancreatic cancer so deadly is its covert and quick spread. Now, a 'time machine' has shown a way to reverse the course of cancer before it spreads throughout the pancreas.

Cancer immunotherapy seeks to turn 'cold' tumors into 'hot' tumors -- those that respond to immunotherapy -- by awakening and enlisting the body's own immune system.

Corneal defects often heal themselves, but serious injuries that are left untreated can result in inflammation, infection, ulceration and even blindness. A new study provides exciting evidence supporting the involvement of aquaporins in corneal cell proliferation and nerve regeneration and suggests aquaporin 5 (AQP5) induction as a potential therapy to accelerate the resurfacing of corneal defects, report scientists.
