Research finds how Candida albicans adapt to low oxygen levels to cause infection

Scientists from Umeå university have shown how the yeast Candida albicans can modulate and adapt to low oxygen levels in different body niches to cause infection and to harm the host.

Molecular hallmarks of tumor hypoxia across 19 cancer types discovered

Unlike healthy tissues, tumors thrive in low-oxygen environments, often acquiring the ability to resist treatment and spread to other sites in the body. Despite being a well-known cause of therapy resistance and metastasis, the impact of low oxygen, known as hypoxia, on tumor cells is poorly understood.

New class of sleeping pill preserves ability to wake in response to danger signals

In a trial of one of the main class of prescription sleeping pills, half the participants slept through a fire alarm as loud as someone vacuuming next to their bed. But a newer alternative preserves the ability to wake in response to danger signals, according to a new research.

Ketogenic supplementation can reduce seizures without dietary restriction, suggests study

The ketogenic diet has proven successful in helping people lose weight and improve their overall health, including those with epilepsy. The low-carb diet transitions the body from burning sugar to burning fat and ketones for energy.

One reason behind frequent miscarriages could be faulty sperms

Scientists at the Imperial College in London have found that one of the reasons behind frequent miscarriages in a woman could be the fault of the sperms of their partners. Recurrent miscarriages are defined as three or more miscarriages that occur before 20 weeks of pregnancy are completed. One in 50 couples in the UK are affected by recurrent miscarriages.

Researchers reveal cause of possible genetic problems in mitochondria

A group of researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine has revealed the importance of eliminating any excess of defective products that might have accumulated in the mitochondria, as its presence generates mitochondrial instability and information loss on the mitochondrial genome.

Study explores energetics and stride variability during gait transition in mammals

A dog's gait, according to the American Kennel Club, is "the pattern of footsteps at various rates of speed, each distinguished by a particular rhythm and footfall." When dogs trot, for example, the right front leg and the left hind leg move together. This is an intermediate gait, faster than walking but slower than running.
