Runner Soh Rui Yong has rewritten the national record for the men’s marathon after clocking 2:23:42 at the Seoul Marathon on Sunday (Mar 17).

Soh’s effort smashed the long-standing previous national mark, which was held by Murugiah Rameshon. Rameshon’s 2:24:22 time at the 1995 SEA Games in Chiang Mai had stood for more than 23 years before Soh’s effort on Sunday.

A prolonged cough may be a sign of tuberculosis


If you have been concerned over a persistent cough which lasted over a month, there is a chance you have contracted tuberculosis (TB).

It typically refers to an infection caused by the bacteria Mycobacterium tuberculosis, and lung infection by the bacteria is termed pulmonary tuberculosis (PTB). Symptoms of PTB may include prolonged cough, bloody phlegm, fever, weight loss, night sweats and shortness of breath.

Dr Mark Ng Chung Wai, family physician at SingHealth Polyclinics Outram and chair of its Infection Control and Infectious Disease Workgroup, said: "According to the 2016 guidelines on the prevention, diagnosis and management of tuberculosis by Singapore's Ministry of Health, the possibility of PTB should be considered in anyone with prolonged cough of more than three weeks, and a chest X-ray should be done."

Harvard University uncovers DNA switch that controls genes for whole-body regeneration

Humans may one day have the ability to regrow limbs after scientists at Harvard University uncovered the DNA switch that controls genes for whole-body regeneration.

Some animals can achieve extraordinary feats of repair, such as salamanders which grow back legs, or geckos which can shed their tails to escape predators and then form new ones in just two months.

Now scientists have discovered that that in worms, a section of non-coding or ‘junk’ DNA controls the activation of a ‘master control gene’ called early growth response (EGR) which acts like a power switch, turning regeneration on or off.

Humans also carry EGR, and produce it when cells are stressed and in need of repair, yet it does not seem to trigger large scale regeneration.
