Currently, if you want to measure someone's blood oxygen levels, you have to use an oximeter that clips onto their finger. An experimental new system, however, is able to check those levels anywhere on the body – and that could mean big things for the field of medicine.

We all know that our body has an "internal clock" which determines when various daily biological processes take place. Problems can occur, however, if that clock is out of sync with the actual time of day. A simple new blood test can reportedly determine if that's the case.

Scientists in Australia have now made a breakthrough they say will allow them to detect low levels of cancer biomarkers in much smaller samples of blood, so much so it could take just prick of the finger.

Numerous biomarkers are being discovered signaling the presence of different cancers, but it’s a challenge to find a single way to track all kinds of cancer. Researchers may have a solution, discovering a protein produced by malaria parasites that is perfectly engineered to detect most cancer cells.

Type O blood, often considered the universal blood type, is most useful in emergency situations, and new research has revealed that an enzyme produced by gut bacteria could be the key to safely and easily turning type A and B blood into type O.

Back in February, the US Food and Drug Administration announced a new blood test that could be used to check patients for concussions. Now, Swiss scientists have developed a handheld device that can be used by laypeople to perform a similar test within minutes, on the spot.

Melanoma, a common type of skin cancer, is traditionally detected via observing changes in irregular moles, and then conducting a skin biopsy. A team has now developed a blood test that can detect melanoma in its early stages, reducing the need for expensive, and frequently unnecessary biopsies.
