Smell Test May Predict Early Stages of Alzheimer’s Disease

Researchers from Columbia University Medical Center (CUMC), New York State Psychiatric Institute, and NewYork-Presbyterian reported that an odor identification test may prove useful in predicting cognitive decline and detecting early-stage Alzheimer’s disease.

Green polymer electrolyte based on N-phthaloylchitosan for dye-sensitized solar cells

A green polymer derived from bio-waste was applied to the dye-sensitized solar cells. Chitosan obtained from the insects’ and crustaceans’ chitin was modified to produce the phthaloylchitosan electrolyte for the dye-sensitized solar cells with efficiency of more than 7%.


Extensive research has been carried out to find a replacement for graphite as anode material. In this work, lithium tin vanadium oxide (LiSnVO4) has been synthesized via sol-gel method.

Fossil is Evidence of Earliest Human Cancer

Although the underlying cause of cancer is not fully known, modern medicine indicates that the disease is likely caused by today’s environment and lifestyles — factors, like diet, obesity and smoking.

Singapore scientists grow mini human brains

Scientists in Singapore have made a big leap on research on the ‘mini-brain’. These advanced mini versions of the human midbrain will help researchers develop treatments and conduct other studies into Parkinson’s Disease[1] (PD) and ageing-related brain diseases.

How comets are formed

Detailed analysis of data collected by Rosetta show that comets are the ancient leftovers of early Solar System formation, and not younger fragments resulting from subsequent collisions between other, larger bodies.
