Big Data Powers Design of ‘Smart’ Cell Therapies for Cancer

Finding medicines that can kill cancer cells while leaving normal tissue unscathed is a Holy Grail of oncology research. In two new papers, scientists at UC San Francisco and Princeton University present complementary strategies to crack this problem with “smart” cell therapies – living medicines that remain inert unless triggered […]

Did early life need long, complex molecules to make cell-like compartments?

Protocell compartments used as models for an important step in the early evolution of life on Earth can be made from short polymers. The short polymers, which better approximate the likely size of molecules available on the early Earth, form the compartments through liquid-liquid phase separation in the same manner […]

For Teens with Migraines, Sleeping In (a Bit) May Help

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 […]

A gel for dosage compensation

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 […]

‘Monster Tumors’ Could Offer New Glimpse at Human Development

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 […]

Sestrin makes fruit flies live longer

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 […]

Stem cell study identifies enzyme with potential for cancer treatment

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 […]

The Link Between Obesity and Puberty

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 […]

Why young people use chemical substances

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. Many of these products can be potentially harmful. The University of Amsterdam studied why young people use these products and how […]

Regulating the regulators

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 […]

Antibiotic Exposure in Children Under Age 2 Associated With Chronic Conditions

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 […]

Commonly used antibiotic shows promise for combating Zika infections

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 […]

Can jellyfish help regeneration medicine and bring us closer to immortality?

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 […]

Imaging method reveals a “symphony of cellular activities”

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 […]

HuBMAP: Hacking the Kidney

Our best estimates show there are over 7 billion people on the planet and 300 billion stars in the Milky Way galaxy. By comparison, the adult human body contains 37 trillion cells. To determine the function and relationship among these cells is a monumental undertaking. Many areas of human health would […]
