While the donor cells in a bone marrow transplant can help cure the patient's blood cancer, they can also cause graft-versus-host disease -- in which donor T cells, a specialized immune cell in the blood, attack the patient's healthy cells.

To further confirm their findings, the researchers directly investigated human patient samples.

Putting less sugar in sodas and reducing the package size of sodas sold in supermarkets may help reduce our collective sugar intake and thus lower the associated health risks. Good news for consumers, but how does it affect manufacturers? Research conducted in the US has shown that marketing diet or sugar-free varieties does not lead to an increase in the overall turnover of soda manufacturers. This is because consumers tend to switch from sugary to sugar-free versions of the same brand. However, reducing the package size of soda does have a positive effect on the sales figures of the brand as a whole.

Physicists have built a new technology on a microchip by combining two Nobel Prize-winning techniques. This microchip could measure distances in materials at high precision, for example underwater or for medical imaging. Because the technology uses sound vibrations instead of light, it is useful for high-precision position measurements in opaque materials. There's no need for complex feedback loops or for tuning certain parameters to get it to operate properly. This makes it a very simple and low-power technology, that is much easier to miniaturize on a microchip. What makes it special is that it doesn't need any precision hardware and is therefore easy to produce. It only requires inserting a laser, and nothing else. The instrument could lead to new techniques to monitor the Earth's climate and human health.

The ability of a cell to divide, to proliferate, is essential for life and gives rise to the formation of complex organisms from a single cell. It also allows the replacement of used cells from a limited number of 'stem' cells, which then proliferate and specialize. In cancer, however, cell proliferation is no longer controlled and becomes chaotic. Researchers have discovered that, in a healthy individual, certain blood immune cells, the monocytes, also have this ability to proliferate, with the aim to replace tissue macrophages, which are essential for the proper functioning of our body.

Space travel has always tested the human body by the effects of the new conditions of altered gravity on biological systems. It has long been known that continuous exposure to microgravity conditions human physiology and causes effects that compromise muscular, sensory, endocrine and cardiovascular functions. But is it also risky to be exposed to altered gravity for short periods of time?

Changes in our REM sleep patterns could potentially be used to diagnose the severity of epilepsy, a new study has suggested. Researchers showed that astrocytes -- star-shaped glial cells that control the local ionic and metabotropic environment of the brain -- exhibit an acid response with REM sleep in mice. They theorize that the acid response could be the underlying drive for specific information processing and generating plasticity during sleep.

Helium -- essential for many medical and industrial processes -- is in critically short supply worldwide. Production is also associated with significant carbon emissions, contributing to climate change. This study provides a new concept in gas field formation to explain why, in rare places, helium accumulates naturally in high concentrations just beneath the Earth's surface. The findings could help locate new reservoirs of carbon-free helium -- and potentially also hydrogen.
