Are tumor cells glutamine addicts?

Researchers found that tumor cells entering a reversible state of proliferation arrest when glutamine is depleted, rather than dying. c-MYC levels are down-regulated upon glutamine deprivation, suggesting it couples transcription to nucleotide availability.

Worldwide survey finds 16 percent rate of acute neurological conditions in critically ill children

A worldwide survey found 16% of critically ill children have acute neurological conditions with brain damage, highlighting the need for transformational ideas to improve outcomes. The study revealed that cardiac arrest was the most common cause of these conditions, followed by traumatic brain injury and central nervous system infection.

With magnetic map, young eels catch a 'free ride' to Europe

Researchers discovered that young European eels detect subtle differences in the earth's magnetic field, helping them swim towards the Gulf Stream, a conveyor belt transporting them to Europe. The findings reveal that juvenile eels use their magnetic map sense to increase their chances of catching a free ride to their destination.

The Lancet Infectious Diseases: Post-SARS, infection rates in China have steadied, but fast-growing and common infections now need attention

A new study tracks infectious disease trends in China over ten years, finding that while overall incidence has declined, some diseases like hydatid disease and hepatitis C are on the rise. The study highlights the need for improved prevention and control measures, particularly in remote border regions.

Catch me if you can

Researchers at Champalimaud Centre for the Unknown identify apterous neurons as key indicators of female receptivity in fruit flies. The discovery links a female's walking speed to her willingness to mate, with silencing these neurons reducing her receptivity.

Timely augmentation to triple oral antihyperglycemic therapy

A new study found that adding a third oral antihyperglycemic agent to metformin and sitagliptin can improve glycemic control in type 2 diabetes patients, overcoming 'clinical inertia' and allowing more than 60% of patients to reach the target HbA1c level. The study, which included over 7,800 participants, also found that the addition o...

Vitamin B diminishes effects of air pollution-induced cardiovascular disease

Researchers found that vitamin B supplements nearly reversed negative effects on heart rate, white blood count, and lymphocyte count in healthy non-smokers exposed to fine particle pollution. The findings suggest a potential preventive pharmacological intervention using B vitamins to contain air pollution health effects.

How to color a lizard: From biology to mathematics

Researchers at Université de Genève discovered that a lizard's skin color pattern forms a cellular automaton, a natural process generated by biological evolution, using a computational system invented by John von Neumann. Computer simulations implemented the discretisation of Turing's equations, which linked the biology-driven mechanis...

Restrictions on trans-fatty acid consumption associated with decrease in hospitalization for heart attack

A study published in JAMA Cardiology found that New York counties with trans-fatty acid (TFA) restrictions on eateries experienced a significant decrease in hospitalization rates for heart attacks and strokes compared to counties without restrictions. The study, which included data from 2002 to 2013, suggests that TFA restrictions may ...
