Fish may cut heart disease risk

Eating fish, rich in omega 3 fatty acids like cod, salmon, herring, and mackerel, may help reduce heart disease risk in young women, a new study has suggested.

In the first population-based study in women of childbearing age, those who rarely or never ate fish had 50 percent more cardiovascular problems over eight years than those who ate fish regularly.

Compared to women who ate fish high in omega-3 weekly, the risk was 90 percent higher for those who rarely or never ate fish.

Researchers used a Danish nationwide population based pregnancy cohort to examine whether or not eating more fish might reduce cardiovascular disease risk in the young women.

About 49,000 women, 15-49 years old, median age of just under 30 years in early pregnancy – were interviewed by telephone or answered food frequency questionnaires about how much, what types and how often they ate fish, as well as lifestyle and family history questions.

The study revealed the even women who ate fish only a couple of times a month benefitted.

“Women who eat fish should find the results encouraging, but it is important to emphasize that to obtain the greatest benefit from fish and fish oils, women should follow the dietary recommendations to eat fish as a main meal at least twice a week,” said Marin Strom, lead researcher.

Fastest-rotating star spins at 600 km per second

Scientists have for the first time discovered the fastest-rotating massive star, which spins at the speed of 600 kilometers per second at the equator and could be the progenitor of some of the brightest explosions in the universe: gamma-ray bursts. The rotational velocity is so high that the star is nearly tearing apart due to centrifugal forces.

The observations were made at the European Southern Observatory’s Very Large Telescope, at the Paranal Observatory in Chile, as part of a survey of the heaviest and brightest stars in a region called the Tarantula Nebula.

The Tarantula Nebula is a region of star formation located in a neighbouring galaxy called the Large Magellanic Cloud, about 160,000 light years from Earth.
The reported star, VFTS 102, is extremely hot and luminous, shining about 100,000 times more brightly than the sun. According to the research team, this star had a violent past and was ejected from a double star system by its exploding companion star.                       

Eye movements to give accurate reading of memory

Eye movements could help tracking memory of individuals more efficiently than behavioural reports alone, a new study has revealed.

According to the study, tracking where and for how long a person focuses his or her eyes ‘can distinguish previously seen from novel materials even when behavioural reports fail to do so’.

“Eye movements are drawn quickly to remembered objects,” said Deborah Hannula, assistant professor at the University of Wisconsin Milwaukee. Apart from the potential for practical application, eye movement methods could be used to examine memory in individuals—like psychiatric patients  – who may have trouble communicating what it is that they remember.
