Fri, 20 Oct 2017 00:00:00 PDT

DNA is perhaps the most famous molecule on earth. Here we explain what it is, what it does, its double helix structure, and why it is so important to life.

Are migraines a self-defense mechanism?

Thu, 19 Oct 2017 07:00:00 PDT

Migraines can severely impact daily functioning and productivity, but could they actually be a mark of the brain's self-protective mechanism?

Colorectal cancer: New, less toxic drug target uncovered

Wed, 18 Oct 2017 00:00:00 PDT

New research uncovers a novel, less toxic drug target for treating colorectal cancer, which currently affects approximately 135,000 people in the U.S.

Brown, blue, green, and hazel: What is the secret behind eye color?

Tue, 17 Oct 2017 08:00:00 PDT

Human eyes display an impressive color palette, ranging from dark brown through shades of green, and to light blue. But what determines these unique hues?

Cancer recurrence may be stopped with immunotherapy

Tue, 17 Oct 2017 00:00:00 PDT

A new study shows how the body's immune system is 'tricked' into not attacking cancer cells, causing relapse. Immunotherapy proves effective in mice.

Leukemia: Cancer cells killed off with diabetes drug

Mon, 16 Oct 2017 09:00:00 PDT

Researchers find that boosting fat cells in the bone marrow using a diabetes drug not only kills off leukemic cells, but it also regenerates healthy ones.

How does rabies cause aggression?

Sat, 14 Oct 2017 00:00:00 PDT

New research investigates the molecular mechanism that allows the rabies virus to induce aggressive behavior in the infected host.

Gut fungi may hold key to metabolic health

Thu, 12 Oct 2017 08:00:00 PDT

Scientists find that feeding mice a high-fat diet changes the structure of fungi in the gut, suggesting that fungi may play a key role in obesity.

'Cell of origin' for Barrett's esophagus identified

Thu, 12 Oct 2017 07:00:00 PDT

Researchers have found an area of unique cells in the lining of the food pipe that can give rise to Barrett's esophagus, a pre-cancerous condition.

Facts about sperm health and lifespan

Thu, 12 Oct 2017 00:00:00 PDT

Learn how long sperm cells are able to survive in a variety of environments outside the body, along with information about sperm health and fertility.

A brief introduction to enzymes

Thu, 12 Oct 2017 00:00:00 PDT

In this article, we explain what enzymes are, what they do, how they work, and give some common examples. We also explain cofactors and inhibition.

Are stem cells and regenerative medicine living up to their promises?

Wed, 11 Oct 2017 08:00:00 PDT

The use of stem cells, materials, or molecules to regenerate tissues and organs promises to revolutionize medicine. How long until this becomes reality?

Targeting 'simple proteins' may extend metabolic healthspan

Tue, 10 Oct 2017 09:00:00 PDT

Scientists have found that deficient levels of fatty acid-binding proteins protect against diabetes, obesity, inflammation, and other age-related diseases.

Liver disease risk may be heightened by gastric acid drugs

Tue, 10 Oct 2017 08:00:00 PDT

A study involving both mice and human participants suggests that common drugs used to reduce gastric acid may increase the risk of chronic liver diseases.

Could the discovery of new immune cells help to treat obesity?

Tue, 10 Oct 2017 07:00:00 PDT

Researchers have discovered a new group of immune cells that contribute to obesity by reducing norepinephrine levels in fat, which prevents fat reduction.

New compound kills cancer without harming healthy cells

Mon, 09 Oct 2017 09:00:00 PDT

A proof-of-concept study shows how a new compound selectively triggers cell suicide in acute myeloid leukemia cells without harming healthy cells.
