Research indicates that starting school later in the morning yields health and academic benefits for high schoolers, whose natural body clock tends toward late-to-bed, late-to-rise habits. While parents raise concerns about drowsy driving, irritation and impaired school performance, a new study led by researchers at UC San Francisco suggests another […]

Male fruit flies have only one X chromosome instead of two like their female counterparts. Therefore, their X chromosome must be twice as active to achieve the same “gene dosage”. If this does not succeed, the animals die. Researchers at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg […]

Finding just the right model to study human development—from the early embryonic stage onward—has been a challenge for scientists over the last decade. Now, bioengineers at the University of California San Diego have homed in on an unusual candidate: teratomas. Teratomas—which mean “monstrous tumors” in Greek—are tumors made up of […]

Reduced food intake, known as dietary restriction, leads to a longer lifespan in many animals and can improve health in humans. However, the molecular mechanisms underlying the positive effects of dietary restriction are still unclear. Researchers from the Max Planck Institute for Biology of Ageing have now found one possible […]

Scientists have found a new mechanism responsible for regulating stem cells in fruit flies, with possible implications for cancer therapies. The study, published by University of Alberta biologists, identifies an inhibition mechanism of an enzyme called Myt1 kinase, which manages how stem cells develop and differentiate during organ development in […]

Puberty, the transformational period where a child reaches physical and sexual maturity, is a near-universal human experience, yet the fundamental processes behind how and when it starts is still a mystery. For girls, puberty can begin as early as eight years old, with most instances of early puberty linked to […]

All over the world, chemical products such as stimulants, but also beauty products, (energy) drinks, vitamins and food supplements have become an integral part of young people's daily lives.

Cocoa is the cosy beverage of choice during dark winter evenings. You wrap yourself in a Christmas blanket, turn on an appropriate movie and just sip your hot cocoa. However, it is not just delicious – it is also good for your brain, as this new study from the University […]

Tiny microRNAs help destroy unwanted messenger RNAs in cells. New research finds how the body keeps them in check. MicroRNAs are short RNA sequences that maintain a tight control on which genes are expressed and when. They do this by regulating which messenger RNA (mRNA) transcripts — the single-stranded templates […]

Children under age 2 who take antibiotics are at greater risk for childhood-onset asthma, respiratory allergies, eczema, celiac disease, obesity and attention deficit hyperactivity disorder, according to a paper written jointly by Mayo Clinic and Rutgers researchers. In a study published in the journal Mayo Clinic Proceedings, the researchers looked at 14,572 children […]

In 2015, hundreds of children were born with brain deformities resulting from a global outbreak of Zika virus infections. Recently, National Institutes of Health researchers used a variety of advanced drug screening techniques to test out more than 10,000 compounds in search of a cure. To their surprise, they found […]

How those inconspicuous animals could be immortal and what potential brings stem cells they store? Not for many of us might be obvious that jellyfish is something more than 95% of water and rest of organic matter. Lack of brain, heart and blood doesn’t indicate them on being on evolutionary […]

Within a single cell, thousands of molecules, such as proteins, ions, and other signalling molecules, work together to perform all kinds of functions — absorbing nutrients, storing memories, and differentiating into specific tissues, among many others. Deciphering these molecules, and all of their interactions is a monumental task. Over the […]

Well managed adults with type 2 diabetes have a 21% higher risk of developing cardiovascular disease (CVD) compared to the general population, according to new research.
