In the bone marrow, blood stem cells via precursor cells give rise to a variety of blood cell types with various functions: white blood cells, red blood cells, or blood platelets. In which cell type a cell develops depends on various factors. The correct dosage of the enzyme MOF at the right time triggers developmental programs in blood stem cells and precursor cells, and the cells differentiate...

A new study shows how an effective but largely abandoned treatment for Type 2 diabetes could be used again in combination with another drug to eliminate problematic side effects.

Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. But, as anyone who has ever played with a toy popper knows, buckling also releases a lot of energy. When the structure of a popper buckles, the energy released by the instability sends the toy flying through the air. Researchers have harnessed that energy and used buckling to their advantage to build...

Researchers have succeeded for the first time in recording, in action, a light-driven sodium pump from bacterial cells. The findings promise progress in the development of new methods in neurobiology.

Tests on new designs for next-gen solar cells can now be done in minutes instead of days thanks to a new system.

Using human population genetics, ancient pathogen genomics and isotope analysis, a team of researchers assessed the population history of the Lake Baikal region, finding the deepest connection to date between the peoples of Siberia and the Americas. The current study also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze Age.

Physicists have boosted their control of the fundamental properties of molecules at the quantum level by linking or 'entangling' an electrically charged atom and an electrically charged molecule, showcasing a way to build hybrid quantum information systems that could manipulate, store and transmit different forms of data.

For the first time, seismologists can characterize signals as a result of some industrial human activity on a continent-wide scale using cloud computing.

Childhood environment and socioeconomic status affect cognitive ability and brain development during adolescence independently of genetic factors, researchers report. The study demonstrates how important the family environment is, not just during early infancy but also throughout adolescence.

Researchers examine the effectiveness of consuming hemp oil extracted from the whole cannabis plant using a chronic neuropathic pain animal model. Researchers showed that legal cannabis hemp oil reduced mechanical pain sensitivity 10-fold for several hours in mice with chronic post-operative neuropathic pain.

You might have heard the advice to avoid eating a poppy seed bagel or muffin before a drug screen, lest you test positive for opiates. This urban legend is rooted in truth because the tiny black seeds contain small amounts of morphine and codeine that can show up in a drug test. Now, researchers have studied how different treatments affect levels of opiates in poppy seeds.

Physicists have measured the flight times of electrons emitted from a specific atom in a molecule upon excitation with laser light. This has enabled them to measure the influence of the molecule itself on the kinetics of emission.

Over 80% of the world's flowering plants must reproduce in order to produce new flowers. This process involves the transfer of pollen between plants by wind, water or insects called pollinators -- including bumblebees. In a new study, researchers at the University of Missouri discovered spiny pollen -- from a native wild dandelion species in the southern Rocky Mountains -- has evolved to attach to...

A new study could usher in a revolutionary development in materials science, leading to big changes in the way companies create modern electronics.

New research found that substituting prolonged sedentary time with sleep was associated with lower stress, better mood and lower body mass index (BMI), and substituting light physical activity was associated with improved mood and lower BMI across the next year.

Spring rains washes away some pollen, but not all. Researchers have found tree pollen fragments can remain airborne for hours after a storm. The tiny pollen particles can exacerbate allergies because they can reach deep in the lungs.

There is much debate about the correct storage of tomatoes. Should tomatoes be in the fridge or kept at room temperature? Researchers investigated whether there are differences in the flavor of ripe tomatoes depending on how they are stored, taking into account the chain of harvesting from farm to fork. No difference was found: the variety of tomato is much more important.

A new study has confirmed and quantified, for the first time, the presence of microplastics in terrestrial and aquatic birds of prey in Florida, including hawks, ospreys and owls. The research is important because birds of prey are critical to a functioning ecosystem. The accumulation of microplastics in their digestive systems could lead to poisoning, starvation and death.

In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation.

Researchers have developed a new strategy that uses optical coherence tomography (OCT) to acquire both the surface and underlying details of impressionist style oil paintings. This information can be used to create detailed 3D reconstructions to enhance the viewing experience and offer a way for the visually impaired to experience paintings.

When researchers asked prospective study participants who they would like to see in videos promoting healthy lifestyle behaviors, the answer was unequivocal: They wanted to see themselves -- that is, other mothers living in low-income households who were overweight or obese. The researchers obliged. And the intervention they designed produced the desired results when it came to improving...

As the world looks to tighten up the illegal capture of wildlife, migratory birds are being threatened by widespread and unsustainable hunting across the Asia-Pacific region. New research has revealed that three quarters of migratory shorebird species in the region have been hunted since the 1970s.

A new study has shown no correlation between obesity and how close you live to fast food restaurants or gyms. Studies from other countries have previously indicated that these factors may be important in adult obesity.

The world's growing population will necessitate a 30-70% increase in food production over the next 3 decades. If we are to succeed, it will require a complete overhaul of the way we produce food. Researchers have now created an overview of solutions that include a number of new technologies that can collectively address this global challenge.
