Breast cancer: Reducing this amino acid could make drugs more effective
New research in cell cultures and mice reveals a surprising link between the essential amino acid leucine and resistance to tamoxifen in breast cancer. (Medical News Today)

House dust microbes degrade cancer-causing chemical
A new study finds that the microbes in our household dust can break down cancer-causing environmental chemicals. However, this benefit comes at a cost. (Medical News Today)

Alzheimer's: Synthetic protein blocks toxic beta-amyloid
Scientists have designed a protein that folds into alpha sheets that can block toxic beta-amyloid in brain cells before it forms into large clumps. (Medical News Today)

Could 'mirror neurons' explain brain mechanisms of empathy?
When rats see other rats in pain, their brains activate the same group of nerve cells that become active when they themselves are in pain, research shows. (Medical News Today)

How whitening strips can damage your teeth
Many people use whitening strips and other bleaching products to make their teeth whiter. However, these often contain a damaging substance. (Medical News Today)

New HIV vaccine could expose latent virus and kill it
Using immune cells in an innovative way, scientists just got closer to developing an HIV vaccine that could make antiretroviral drugs a thing of the past. (Medical News Today)

Researchers explore 'completely novel, nontoxic' IBD treatment
Researchers identify a new method that could allow them to treat and even prevent the development of inflammatory bowel disease, among other conditions. (Medical News Today)

Research in mouse models has revealed a surprising link between the activity of immune cells in the lungs and their ability to process simple sugars. (Medical News Today)

Can blocking a single protein tackle depression, obesity, and pain?
New research finds that a 'highly selective inhibitor' of a single protein can relieve stress, diet-induced obesity, and improve mood in mice. (Medical News Today)

Why do antidepressants fail for some?
Differences in genes and structures of nerve cells that make and use serotonin could explain why some people with major depression do not respond to SSRIs. (Medical News Today)

Osteoporosis: New tools help pinpoint potential risk genes
Genome analysis and 3D DNA studies helped scientists to identify two new genes that impact bone-producing cells to potentially alter osteoporosis risk. (Medical News Today)

How does tumor acidity help cancer spread?
A pH-probe helps scientists map acidity in tumors and see how acidification alters gene expression in ways that increase cancer's invasiveness and spread. (Medical News Today)

How destroying a tumor promoter could lead to new cancer treatments
Mutated p53 tumor suppressor protein is a key driver of most cancers. Now, scientists have identified its mechanism of stability and how to disrupt it. (Medical News Today)

Heart failure: New drug could halt disease and improve heart function
A molecule that stops two proteins from interacting and impairing heart function halted heart failure and improved heart pumping capacity in rats. (Medical News Today)

Parkinson's: Study reveals how cancer drug reduces toxic protein in brain
An analysis of trial results reveals the mechanism through which the cancer drug nilotinib increases brain dopamine in people with Parkinson's disease. (Medical News Today)

Why do we sleep? Scientists find brain repair mechanism
How does sleep act in the brain, at the cellular level? A new study in zebrafish identifies and explains the beneficial effects of slumber. (Medical News Today)

IBD: A low-calorie plant diet relieves inflammation, repairs gut
Cycles of a low-calorie, plant-based diet reduced inflammation, prompted tissue repair, and promoted good bacteria in intestines of mice with IBD symptoms. (Medical News Today)

Pancreatic cancer: Two-hit treatment approach shows promise
Autophagy inhibitors could be more potent against pancreatic cancer by first applying a drug that makes the cancer cells dependent on autophagy for energy. (Medical News Today)

Sleeping more on weekends does not make up for past sleep loss
The results of a new study warn that weekend lie-ins cannot effectively erase the harm resulting from insufficient sleep throughout the working week. (Medical News Today)

ALS: New technique prevents toxic protein deposits in cells
Clumps of faulty TDP-43 protein inside nerve cells are common in ALS and other neurological diseases. Could this new technique offer a way to prevent them? (Medical News Today)

Could these brain changes explain phantom limb?
Changes in communication between sensory and motor areas of the brain after lower limb amputation could explain phantom sensation, even without pain. (Medical News Today)

Alzheimer's: 'Holy herb' extract shows promise as future treatment
A laboratory screen found that a compound in the Yerba santa medicinal plant protects against several age-related triggers of death in mouse nerve cells. (Medical News Today)

This Japanese plant could hold the key to extended youth
New research finds that a compound in a traditional Japanese medicinal plant could boost cellular health and protect against the ill effects of aging. (Medical News Today)

Bacteria living on insects could provide new antibiotics
