Wasp venom provides clues to how genes take on new functions

Amid the incredible diversity of living things on our planet, there is a common theme. Organisms need to acquire new genes, or change the functions of existing genes, in order to adapt and survive.

Could the mTOR pathway be used to protect against cancer?

The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.

Researchers create new camera that can register fast processes in transparent specimens

Researchers from ITMO University have built a setup for recording holograms of tiny objects like living cells with a femtosecond speed. The new method allows one to reconstruct phase topography of a studied sample according to deformations that emerge in a laser pulse when it passes through the specimen.

Scientists develop new algorithm to decipher how immune system recognizes and binds antigens

Scientists from St. Jude Children's Research Hospital and Fred Hutchinson Cancer Research Center have developed an algorithm that functions like a Rosetta Stone to help decipher how the immune system recognizes and binds antigens.

Could a blood test predict how cancer spreads in children?

Traditionally, we use biopsies to try to predict how cancer spreads. There are a number of molecular markers that are used, but biopsy is a limited approach. Now, the current trend is to use liquid biopsy, which is basically a blood sample.

MIT biologists identify how the immune system eliminates genetically imbalanced cells

Most living cells have a defined number of chromosomes: Human cells, for example, have 23 pairs. As cells divide, they can make errors that lead to a gain or loss of chromosomes, which is usually very harmful.

Mutations identified that enable human transmission of avian flu

A systematic mutation analysis has shown that changes in just three amino acids of the avian influenza H7N9 virus receptor binding protein confers specificity for human cells.

Developing synthetic mediums for growing organoids

Organoids are bits of tissue grown in vitro, in a near-physiological 3D setting. The particularity consists in the fact that organoids retain features of the patient they are derived from, even when cultured outside of the human body. This is very different from what traditional, conventional cell culture has been able to do over the past 50 years or so.

Salk scientist uses mathematical framework to better understand how cell types divide work

Despite advances in neuroscience, the brain is still very much a black box--no one even knows how many different types of neurons exist.

Molecular biologists identify enzyme that activates and ‘supercharges’ cellular machinery

St. Jude Children's Research Hospital molecular biologists have identified an enzyme that activates and "supercharges" cellular machinery that controls how cells become specialized cells in the body.

New protocol offers faster and more effective way to obtain astrocytes from stem cells

Neurons have long enjoyed the spotlight in neuroscience--and for good reason: they are incredibly important cellular actors. But, increasingly, star-shaped support cells called astrocytes are being seen as more than bit players in the brain's rich pageant.

Scientists reveal 12-hour autonomous biological clock that coordinates bodily functions

Some bodily activities, sleeping, for instance, mostly occur once every 24 hours; they follow a circadian rhythm. Other bodily functions, such as body temperature, cognitive performance and blood pressure, present an additional 12-hour cycle, but little is known about the biological basis of their rhythm.

Scientists locate crucial off-switch for central cell control

As the cell's molecular control center, the mTor kinase regulates cellular metabolism, growth and division. However, in cells affected by pathological change, the regulation goes array.

Study unravels mystery of how nerve cells are damaged in neurodegenerative diseases

A new study has uncovered a molecular mechanism in the prion protein, a protein responsible for neurodegenerative diseases, which may explain why nerve cells degenerate in these disorders.

Research into cellular senescence may lead to new ways of treating age-related disorders

One of the things that happens to our bodies as we age is that certain cells start to accumulate. So-called senescent cells – cells that "retire" and stop dividing but refuse to die – are always present, and they even serve some important functions, such as in wound repair.

Researchers discover innovative way to produce hematopoietic stem cells

A study published on May 17 in Nature, discovers an innovative method to produce infinite supply of healthy blood cells from the readily available cells that line blood vessels. This achievement by the researchers at Weill Cornell Medicine marks the first time that any research group has generated such blood-forming stem cells.
