Study finds obesity 'fuels' leukemia, but a combo using popular weight-loss drugs may stop
Study finds obesity 'fuels' leukemia, but a combo using popular weight-loss drugs may stop
Obesity can act as fuel for leukemia, according to a study led by Indiana University School of Medicine scientists. To help patients facing aggressive blood cancers overcome this metabolic risk, researchers identified a potential treatment strategy that combines popular weight-lo
Dialing back stiffness may protect muscles in myotonic dystrophy
For decades, researchers studying myotonic dystrophy type 1 (DM1) have focused on the disease's underlying genetic cause: a mutation that produces a toxic form of RNA, disrupting the normal processing of thousands of genetic messages inside cells. While scientists have known this

Herpes immune response linked to Alzheimer's disease
New research has demonstrated a mechanistic link between the immune response to herpesviruses—the family of viruses related to cold sores, childhood infections and mononucleosis—and an increased risk of Alzheimer's disease. A team of scientists from Cardiff University's School of
Sound waves guide cultured cells to form vessel-like networks within one week
With the aid of physical forces—in this case, sound—it is possible to actively steer the formation of engineered tissue. For example, sound waves can be used to create functional vascular networks with blood vessel-like structures in vitro. Scientists at the Center for Molecular
Genetic safeguard protects the female heart—and what happens when it's lost
Men and women are not born with the same risk of heart disease, and for decades scientists have struggled to explain why. A new study from the University of North Carolina at Chapel Hill, published in Genes & Development, offers an answer: The female heart depends on a molecular
Scientists discover how macrophages age differently throughout the body
Scientists discover how macrophages age differently throughout the body
Why does the immune system become less effective as we age? A new USC study published in BMC Biology offers fresh insights by examining a key immune cell type across tissues: macrophages.
Scientists uncover genetic clues from a tumor-prone reptile that could advance cancer rese
Scientists uncover genetic clues from a tumor-prone reptile that could advance cancer rese
A new study led by experts at the University of Nottingham suggests a pet gecko with an unusually high risk of tumors may be a promising model for understanding how cancer develops and spreads. The findings of the study, which are published in BMC Biology, could help explain why

As heat waves loom, scientists wonder how humans will adapt
As heat waves loom, scientists wonder how humans will adapt
Temperatures are set to soar in the US around the July 4 holiday, a week after Europe struck new records. With experts predicting more intense and more frequent heat waves in the future, can our bodies adapt?

Autism may have two distinct subtypes that vary by brain activity
Evidence is mounting that there are distinct subtypes of autism, and now, scientists have found that the condition can vary according to the strength of people's brain connections

The race to understand how and when Thwaites glacier will collapse
The loss of Antarctica’s doomsday glacier would transform our planet. Now scientists are revealing the secrets of this remotest of places, and asking the question: is its demise inevitable?
Slowdown of AMOC ocean current may be gradual and reversible
Scientists worry that a surge of meltwater from Greenland could irreversibly collapse the Atlantic Meridional Overturning Circulation, but new modelling suggests the weakening of the current could be reversed if CO2 levels come back down
