Obese have a greater sense of smell for food

A new research has stated that overweight people have greater sense of smell for food.
Researchers from the University of Portsmouth said that their findings may explain why it’s difficult for some people to stay slim. Experts already know that part of the brain that processes information about odour is also connected to the feeding centres of the brain.
Stafford and his team asked 64 volunteers to take part in a series of experiments that tested their smelling ability and they study found that people appear to be slightly better at smelling food odours after they have eaten rather than when they are hungry.
His team found that people who are overweight — those with a higher body mass index or BMI — have a far heightened sense of smell for food compared to slim people, particularly after they have eaten a full meal.

Rheumatoid arthritis can lead to typing difficulties

A new research at University of Pittsburgh has revealed that joint damage caused by rheumatoid arthritis can lead to difficulties in typing. Rheumatoid arthritis is a chronic disease that causes pain, stiffness, swelling, and limitation in the motion and function of multiple joints.

Researchers hypothesised that touch typists with structural deformities caused by RA would have significantly different typing postures, motions and speeds than those without structural deformities.

They found that participants with structural deformities due to RA showed more whole hand and wrist motions — commonly called the ‘hunt-and-peck’ method of typing — than those without (64 per cent) structural deformities.

Finally, researchers found that significantly fewer participants with structural deformities used a wrist support, and there was no significant difference in typing speed between the two groups of participants.

Arsenic improves survival for leukaemia patients

Arsenic, a toxic compound, has a significant positive effect on the survival of patients with acute leukaemia. Wake Forest University Baptist Medical Centre researchers conducted the study.

“Patients with acute leukaemia can achieve remission with standard treatment, but it often comes back,” said Bayard L Powell. “Arsenic trioxide is then used to get them back into remission. For this study, we used arsenic as an early ‘consolidation therapy’ after the initial standard treatment to essentially, as one of our first patients described, ‘seal the deal’ the first time around. Not only did the leukemia rarely return in the patients who received the arsenic, those patients also lived longer.”
