After searching 12 years for bipolar disorder’s cause, research team concludes it has many

Nearly six million Americans have bipolar disorder, and most have probably wondered why. After more than a decade of studying over 1,100 of them in-depth, a team of scientists has an answer -- or rather, seven answers.

How much soil goes down the drain: New data on soil lost due to water

According to a new study, almost 36 billion tons of soil is lost every year due to water, and deforestation and other changes in land use make the problem worse. The study also offers ideas on how agriculture can change to become a part of the solution from being part of the problem.

Heavy-petroleum fuels raising vanadium emissions

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.

3-D nanoscale imaging made possible

Imaging at the nanoscale is important to a plethora of modern applications in materials science, physics, biology, medicine and other fields. Limitations of current techniques are, e.g. their resolution, imaging speed or the inability to look behind opaque objects with arbitrary shapes. Scientists have now demonstrated a method for meeting this challenge with stunning properties.

Vitamin deficiency in later life

One in two persons aged 65 and above has suboptimal levels of vitamin D in the blood and one in four older adults has suboptimal vitamin B12 levels.

Madagascar’s vanilla situation is anything but plain

Now that vanilla is the second most expensive spice in the world, farmers need rely on armed guards to protect crops.

Cancer immunotherapy may work better in patients with specific genes

Investigators have been trying to understand why and have recently found how an individual's own genes can play a role in the response to the immunotherapy drugs.

New catalyst meets challenge of cleaning exhaust from modern engines

Researchers have created a catalyst capable of reducing pollutants at the lower temperatures expected in advanced engines.

Visitor patterns and emerging activities in Finish national parks revealed by social media posts

Social media data provide a reliable information to support decision-making in national parks.

First-of-its-kind chemical oscillator offers new level of molecular control

Researchers successfully constructed a first-of-its-kind chemical oscillator that uses DNA components. DNA molecules that follow specific instructions could offer more precise molecular control of synthetic chemical systems, a discovery that opens the door for engineers to create molecular machines with new and complex behaviors. « Previous PageNext Page »
