NO NEED TO DELAY PREGNANCY AFTER MISCARRIAGE

A persistent apprehension in the minds of the ladies who have experienced a miscarriage is when to try again to concieve.A brand new exeptional study suggests that there is no reason for most ladies to avoid getting pregnant in the near future after a miscarriage.This remarkable new study concludes that the earlier a woman conceives again, the better her chances of having a healthy pregnancy.

Specifically, ladies who conceive within six months after a miscarriage are less likely to miscarry again or experience other pregnancy-related complications when compared with ladies who wait for longer periods of time.

Study researcher Sohinee Bhattacharya, MD, an obstetrician at the University of Aberdeen in Scotland feels that women must be in a positive frame of mind and proceed towards making another attempt at concieving as soon as possible.

Exactly how long a woman ought to wait to conceive after a miscarriage is controversial. Some doctors recommend trying again as soon as feasible, while guidelines from the World Health Organization (WHO) demand waiting for at least six months, & others recommend waiting for as long as 18 months.

The new study included information on subsequent pregnancies achieved among 30,937 ladies who miscarried in the course of their first pregnancy. The researchers did not have information about the reason for the miscarriage.

Interestingly, ladies who became pregnant within six months of miscarriage had better outcomes as well as a lower risk of complications than their counterparts who waited longer to conceive after a miscarriage.

Ladies who waited two years to conceive after their miscarriage ran a greater risk for potentially life-threatening ectopic pregnancy (when the fertilized egg has implanted outside the uterus, usually in the fallopian tubes) and/or pregnancy termination than ladies who conceived earlier. These ladies were also more likely to deliver by cesarean section or give birth to premature or low-birth-weight children than ladies who became pregnant within six months after their miscarriage, the study shows.

The study did include ladies who had miscarried later in pregnancy, & the findings were broadly similar to those who had miscarriages earlier in their pregnancy.

There's some subgroups of ladies who may need to wait longer before becoming pregnant again, including ladies who show signs of an infection, the researchers caution.

WILD CAT MIMICS MONKEY SOUNDS TO CAPTURE PREY

One wild cat species goes beyond physical camouflage to capture its prey - it disguises its voice,mimicking the calls of its victims,a new study finds.

Margays,wild cats native to the Amazon,have been observed imitating the calls of squirrel - sized monkeys known as pied tamarins.This is the first recorded instance of a wild cat species in the Americas copying the calls of its prey,the researchers say.In addition to physical agility,this cunning move gives them a psychological advantage over their prey which is mesmerizing in the literal sense of the word.

U.S.A TO FEEL MORE HEAT,MORE OFTEN IN COMING YEARS

A study conducted by the Stanford University has concluded that although the US and over 100 other countries agreed in Copenhagen to reduce emissions in order to hold the increase in global temperature below two degree celcius,that is just not enough to counter the damage already done.

The researchers say that in the next 30 years,the US could see an increase in heatwaves. The heat is most likely to reduce the yields of major crops like corn,soybean,cotton and wine grapes.

The scientists used 12 models to predict CO2 emissions in the next three decades.

KIDS WHO EAT WITH MOM,DAD THINNER

In a new study carried out by the Greek researchers,interviews of 1,138 children between ages 9-13 were conducted.The interviews centered around their diets and physical activities.

It was observed that kids who had meals with their families,had lower body mass index,smaller waistlines and less body fat - the reason being,a high intake of vegetables from traditionally cooked meals.

A surprise outcome of the study was that indulgence in fast food and a sedentary lifestyle did not contribute to obesity.

FORMULA TO PREDICT PHANTOM TRAFFIC JAMS

Researchers at the Massachusetts Institute of Technology have devised a model that can predict traffic jams.They have come up with a formula of phantom jams,based on the equations that describe detonation waves caused by explosions.

Phantom jams are those that appear for no apparent reason,in the absense of an accident or roadworks.

In high - density traffic,even a small disturbance,such as a driver braking too hard,becomes amplified as the cars behind react more strongly.The mathematicians call such phantom jams 'jamitons'.

Aslan Kasimov,a lecturer at MIT's Department of Mathematics,and the team found that the jamitons behave like detonation waves in that they have a 'sonic point',a sort of bottleneck,which seperates the traffic flow into upstream and downstream areas.

The MIT team said "Variables such as traffic speed and traffic density are used to calculate the conditions under which a jamiton is formed and how fast it will spread."

The mathematical model will not help break up jams once they have formed - drivers will simply have to wait them out.But it will allow civic planners to predict where jams are most likely to occur.

2 SPOONFULS OF SUGAR IN CUP OF TEA KEEPS STRESS AT BAY

Researchers from University of New South Wales and Queensland University found that sweetened drinks make people less aggressive and argumentative as the sugar rush provides the brain with the energy it needs to keep impulses under control,stopping people from lashing out when under pressure.

2 spoonfuls of sugar in a cup of tea (or any other beverage) before a stressful meeting helps one to maintain his cool even in the most trying circumstances by keeping his emotions under control.

The researchers gave lemonade to a group of people.Some was sweetened with sugar,the rest with an artificial sweetener.The volunteers were set a series of stressful tasks,culminating in preparing a speech.After giving their talk,some were provoked by being told that the content was boring and disappointing.Those who had drunk the sugary lemonade rose less to the bait.

TELESCOPE IMPLANT INSIDE EYE TO FIGHT AGE RELATED BLINDNESS

Strange as it may seem,US health officials have approved a first-of-its-kind technology to counter a leading cause of blindness in older adults - a tiny telescope implanted inside the eye.The Implantable Miniature Telescope aims to help in the end stages of incurable age - related muscular degeneration,a creeping loss of central vision that blocks reading.watching TV,eventually even recognizing faces.The telescope is surgically inserted into one eye for better central vision,while leaving the other eye alone for peripheral vision.The brain then fuses two views into a single image.The Food and Drug administration said 90 % of telescope recipients had their vision improve by at least two lines on an eye chart.
