Discovery in human acute myeloid leukemia could provide novel pathway to new treatments

A study published in Cell Reports reveals that human acute myeloid leukemia (AML) stem cells are dependent on the transcription factor RUNX1, which could lead to lasting remissions or even cures. The researchers used induced pluripotent stem cells from a patient with AML to recreate leukemia stem cell biology in the lab.

Boosting energy efficiency of 2D material electronics using topological semimetal

A research team from Singapore University of Technology and Design has discovered a new strategy to resolve contact resistance in 2D semiconductor devices. They found that an ultrathin film of Na3Bi can be used as a metal contact with low contact resistance, retaining the intrinsic electronic properties of 2D semiconductors.

Measuring climate change

Researchers have identified similarities and differences in ocean acidification on both coasts of North America, with the east coast experiencing a near-equilibrium pattern and the west coast showing enhanced acidification due to upwelling. The study highlights vulnerable hot spots, particularly in northern waters where rising carbon d...

COVID-19 could be a seasonal illness

A study found an association between lower humidity and increased COVID-19 cases in Sydney. Lower humidity makes airborne viruses more transmissible due to smaller aerosol size, increasing exposure for others. Further research is needed to determine this relationship's extent and impact on case notification rates.

CeMM study reveals how a master regulator of gene transcription operates

Researchers discovered that the Mediator complex selectively safeguards a small set of cell-type-specific genes, which form densely connected regulatory circuits. This finding suggests that Mediator is not generally required for all gene transcription and instead plays a crucial role in directing cell-type-specific functions.

The Lancet: Most comprehensive study to date provides evidence on optimal physical distancing, face masks, and eye protection to prevent spread of COVID-19

A comprehensive review of 172 studies found that physical distancing of at least 1 meter reduces COVID-19 transmission risk, while face coverings and eye protection may provide additional benefits. However, no intervention offers complete protection, emphasizing the need for combined measures.

Hot stars are plagued by giant magnetic spots, ESO data shows

Extreme horizontal branch stars, with four to five times hotter than the Sun, show giant magnetic spots that cause regular brightness variations. These spots are also linked to superflare events, explosions of energy several million times more energetic than similar eruptions on the Sun.

Universal virus detection platform to expedite viral diagnosis?

Researchers at KAIST developed a universal virus detection platform using reactive polymer-grafted double-stranded RNAs, which can detect viruses without prior knowledge of their genomic sequences. This platform provides enhanced sensitivity and can be used to quickly differentiate infected populations from non-infected ones.
