Could our body clock help to prevent cancer?

Fri, 08 Dec 2017 00:00:00 PST

Researchers reveal how a newly discovered role for our biological clock, or circadian rhythm, may help to prevent or treat cancer.



Alzheimer's brain damage halved with gene-targeting compound

Wed, 06 Dec 2017 09:00:00 PST

Scientists have designed a molecule that can interfere with the production of the APOE protein. Mouse tests reveal that the compound prevents brain damage.



A high-fat diet without the weight gain? Study says it's possible

Wed, 06 Dec 2017 08:00:00 PST

Researchers have discovered that activating the Hedgehog signaling pathway in mice fed a high-fat diet prevented them from gaining weight.



Battle of the sexes: Are women fitter than men?

Tue, 05 Dec 2017 08:00:00 PST

A new study investigates how women's bodies respond to aerobic fitness in comparison with men's, and it suggests that women are naturally more athletic.



Killing cancer softly: New approach halts tumor growth

Fri, 01 Dec 2017 00:00:00 PST

Cancer therapy can sometimes, paradoxically, help the cancer to spread. New research shows why that is, and what can be done to stop it.



The effects of skipping breakfast depend on your weight

Wed, 29 Nov 2017 09:00:00 PST

New research suggests that eating breakfast regularly or skipping it altogether can affect lean and obese people in very different ways.



Cancer stem cells destroyed by drug-filled nanoparticles

Wed, 29 Nov 2017 07:00:00 PST

Scientists show how drug-laden nanoparticles can find and destroy cancer stem cells that hide in tissue for years before causing the cancer to return.



Flu and colds: Why do we cough?

Tue, 28 Nov 2017 08:00:00 PST

Whether dry or chesty, coughing fits are customary when flu or the common cold is involved. But what causes us to cough? We investigate.



Prostate cancer: How immune cells promote tumor growth

Tue, 28 Nov 2017 00:00:00 PST

New research analyzes prostate cancer cells and finds the reason why the body's own immune system may promote progression of the disease.



Houseflies may carry more diseases than previously thought

Mon, 27 Nov 2017 10:00:00 PST

Researchers examined the microbiomes of 116 houseflies and blowflies, and found that they carry many bacteria that are harmful to humans.



Malaria drugs could help to combat cancer

Fri, 24 Nov 2017 09:00:00 PST

Researchers reveal how two drugs used to treat malaria, called chloroquine and hydroxychloroquine, could help in the fight against cancer.



More than just 'chemo brain': Cancer impacts memory, too

Thu, 23 Nov 2017 00:00:00 PST

After chemotherapy, many people report experiencing 'chemo brain,' characterized by impaired cognitive function. But could cancer itself be to blame?



How do cancer cells start to spread? Study sheds light

Wed, 22 Nov 2017 09:00:00 PST

Using a 3-D collagen matrix, researchers have discovered how the environment surrounding a tumor encourages cancer cells to metastasize.



How cinnamon can help you to burn holiday fat

Wed, 22 Nov 2017 08:00:00 PST

New research reveals how the essential oil that gives cinnamon its unique flavor and smell makes fat cells burn energy instead of storing it.



Cancer cell growth halted with cold and flu drug

Tue, 21 Nov 2017 09:00:00 PST

A drug commonly used to ease cold and flu symptoms can starve cancer cells of the proteins they need to grow and divide, a new study finds.



E-cigarette flavorings may impair heart muscle function

Mon, 20 Nov 2017 00:00:00 PST

By studying heart muscle cells in the laboratory, researchers found that some flavorings in e-cigarette liquids, such as citrus, may have harmful effects.



Type 1 diabetes: Could modified blood stem cells lead to a cure?

Fri, 17 Nov 2017 07:00:00 PST

Researchers found that modifying blood stem cells to raise their levels of a T cell-blocking protein called PD-L1 reversed hyperglycemia in diabetic mice.



What is the immune system?

Fri, 17 Nov 2017 00:00:00 PST

The immune system defends our body against "foreign" invaders. Here, we explain how it works, and the cells, organs, and tissues that are involved.



There is such a thing as 'fault-free obesity,' after all

Wed, 15 Nov 2017 00:00:00 PST

New research shows how a genetic mutation may lead to obesity by increasing the size of the body's fat cells and making them absorb glucose faster.



Deadly brain tumors halted by blocking telomere protein

Mon, 13 Nov 2017 09:00:00 PST

By blocking TRF1, a protein involved in the protection of telomeres, researchers were able to halt the growth of glioblastoma tumors in mice.



Chronic fatigue syndrome: Changes in brain chemistry found

Mon, 13 Nov 2017 08:00:00 PST

A new study identifies brain chemistry changes in people with chronic fatigue syndrome and Gulf War illness, making the two conditions easier to diagnose.



Bugs in the basement? Here's why

Fri, 10 Nov 2017 07:00:00 PST

A new study of arthropods in 50 U.S. homes suggests that their diversity is influenced more by access to the outdoors than the behavior of human residents.



'Daytime wounds heal faster.' Here's why I disagree

Fri, 10 Nov 2017 02:00:00 PST

Researchers say that burn wounds heal faster when they occur during the day, but others argue there are not enough data to draw conclusions.



How type 2 diabetes can be reversed with a low-calorie diet

Fri, 10 Nov 2017 00:00:00 PST
