Study: Actually, potted plants don't improve indoor air quality

Plants can help spruce up a home or office space, but claims about their ability to improve the air quality are vastly overstated, according to research out of Drexel University. A closer look at decades of research suggesting that potted plants can improve the air in homes and offices reveals that natural ventilation far outpaces plants when it comes to cleaning the air.

Membrane fusion at each organelle requires conserved proteins: Rab-GTPases, effector tethering complexes, Sec1/Munc18 (SM)-family SNARE chaperones, SNAREs of the R, Qa, Qb, and Qc families, and the Sec17/α-SNAP and ATP-dependent Sec18/NSF SNARE chaperone system. The basis of organelle-specific fusion, which is essential for accurate protein compartmentation, has been elusive. Rab…

SMART discovers breakthrough way to look at the surface of nanoparticles

Researchers have discovered a way for scientists to study the properties of a nanoparticle without damaging it — something that is not possible with widely used chemical processes today. The revolutionary technique is also cheaper and faster than existing methods, and uses machines that are readily available in labs today. The breakthrough paves the way for researchers across different sectors an

Feast or famine: Scientists find key bio 'switch' that helps cells adapt

Scientists, in a study published in Molecular Cell, found that a chemical mark on histones – a key protein involved in the function of our DNA – occurs naturally under nutrient-limited conditions as cells change the way they make energy, and serves to repress genes that would otherwise drive cell growth. The chemical mark is called crotonylation, and until now its function has not been well unders

You should change your area of expertise every 10 years. Here's why.

People often mistake young minds as having a prerogative in making great scientific discoveries. However, finding innovative solutions is less a matter of youth and more about having a fresh take on things, a subject. One tip in developing innovative solutions is to venture off from your original field of study — in that tangent, you'll be able to grasp things with a "fresh" take. You may be able
