Finding blood clots before they wreak havoc

Finding blood clots before they wreak havoc | Biosciencia News | Scoop.it
Simple urine test developed by MIT engineers uses nanotechnology to detect dangerous blood clotting.
Biosciencia's insight:

Life-threatening blood clots can form in anyone who sits on a plane for a long time, is confined to bed while recovering from surgery, or takes certain medications.

Can a mammoth carcass really preserve flowing blood and possibly live cells?

Can a mammoth carcass really preserve flowing blood and possibly live cells? | Biosciencia News | Scoop.it

Yesterday brought a flurry of news stories trumpeting a mind-blowing discovery from the lost world of the last ice age: a 10,000-year-old woolly mammoth carcass that preserves muscle tissue the color of fresh meat and blood in liquid form, despite the –10 degrees Celsius temperatures in the Novosibirsk Islands, where Russian researchers discovered the beast.

Biosciencia's insight:

Wow! I mean, there have been some spectacular mammoths to emerge from this part of the world — the baby mammoth Lubya, discovered in 2007, for example. But muscle tissue like fresh meat? Liquid blood? The possibility of live cells? Sounds amazing, right?

Nanotechnology could help fight diabetes: Injectable nanogel can monitor blood-sugar levels, secrete insulin when needed

Nanotechnology could help fight diabetes: Injectable nanogel can monitor blood-sugar levels, secrete insulin when needed | Biosciencia News | Scoop.it
Injectable nanoparticles developed at MIT may someday eliminate the need for patients with Type 1 diabetes to constantly monitor their blood-sugar levels and inject themselves with insulin.
Biosciencia's insight:

"Insulin really works, but the problem is people don't always get the right amount of it. With this system of extended release, the amount of drug secreted is proportional to the needs of the body"

Octopus' blue blood allows them to rule the waves

Octopus' blue blood allows them to rule the waves | Biosciencia News | Scoop.it
Worldwide colonization by octopods is in their blood! They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues.
Biosciencia's insight:

The researchers found that the forms of haemocyanin of the Antarctic octopod Pareledone charcoti, are genetically and functionally different from the temperate and warmer climate octopods, facilitating oxygen release at sub-zero temperatures.

Synthetic Blood Development Given The Go-Ahead At Scottish Center For Regenerative Medicine: Eat Your Heart Out 'True Blood' Fans

Synthetic Blood Development Given The Go-Ahead At Scottish Center For Regenerative Medicine: Eat Your Heart Out 'True Blood' Fans | Biosciencia News | Scoop.it
Adult stem cells will be used to develop synthetic blood, which will be designed to assist blood banks and minimize infusion-related infections.
Biosciencia's insight:

After decades mired in controversy, legal battles, and ethical dilemmas the United Kingdom's Medical and Healthcare products Regulatory Agency (MHRA) granted a license that will allow researchers at the Scottish National Blood Transfusion Service, Edinburgh University, and Roslin Cells to set up a facility for the testing of synthetic blood in human trials.

Blood hormone restores youthful hearts to old mice

Blood hormone restores youthful hearts to old mice | Biosciencia News | Scoop.it
Protein relieves age-related stiffening and thickening of cardiac muscle.
Nature News doi: 10.1038/nature.2013.12971
Biosciencia's insight:

If proven to be effective in humans, a protein that reverts the effects of ageing in mouse hearts could provide relief for a condition that is otherwise difficult to treat.
