Alzheimer's could be diagnosed early with sniff tests

Thu, 17 Aug 2017 08:00:00 PDT

A damaged sense of smell correlates with other biomarkers of Alzheimer's disease, providing hope that smell tests might help diagnose the disease earlier.

Cancer drugs that halt tumors can also shrink them

Thu, 17 Aug 2017 07:00:00 PDT

New research reveals how CDK4/6 inhibitors, approved cancer drugs that halt tumors, can also shrink them in some cases by promoting anti-tumor immunity.

Wed, 16 Aug 2017 07:00:00 PDT

Using tissue engineering, researchers show a way forward for treating type 1 diabetes by implanting insulin-producing islet cells under the skin.

A metabolic treatment for pancreatic cancer?

Wed, 16 Aug 2017 06:00:00 PDT

Pancreatic cancer is now the third leading cause of cancer mortality. Its incidence is increasing in parallel with the population increase in obesity, and its five-year survival rate still hovers at...

Habitual cannabis use alters brain oxygen

Wed, 16 Aug 2017 00:00:00 PDT

The brains of chronic cannabis users have an altered blood flow and process oxygen differently, which may impact brain function, a study suggests.

Alzheimer's: Low serotonin levels may drive development

Tue, 15 Aug 2017 09:00:00 PDT

A new study examines serotonin transporters and suggests that rather than being an effect of Alzheimer's disease, low serotonin may cause the illness.

How do broken bones heal?

Tue, 15 Aug 2017 08:00:00 PDT

Find out what gives our bones their remarkable ability to heal breaks in a finely tuned process that involves stem cells, cartilage, and bone.

How the brain recognizes familiar faces

Tue, 15 Aug 2017 00:00:00 PDT

There's nothing quite like the rush of recognition that comes from seeing a familiar face.

Hair growth stimulated using stem cells

Mon, 14 Aug 2017 08:00:00 PDT

Using 3-D organoids made from stem cells, scientists managed to uncover a six-step process by which hair grows and stimulated hair growth.

Sleep biology discovery could lead to new insomnia treatments that don't target the brain

Mon, 14 Aug 2017 06:00:00 PDT

UCLA scientists report the first evidence that a gene outside the brain controls the ability to rebound from sleep deprivation - a surprising discovery that could eventually lead to greatly improved...

Leukemia: Mushroom protein could be used in future treatments

Sun, 13 Aug 2017 00:00:00 PDT

A protein found in the edible mushroom commonly known as "shaggy ink cap" has the potential to kill leukemia T cells, a new study suggests.

Cell death: Is our health at risk?

Fri, 11 Aug 2017 08:00:00 PDT

Every day, 50 billion cells in our bodies die and are replaced by new cells. Most of the time, there are no side effects - but things can go wrong.
