Detailed cross-section of another galaxy reveals surprising similarities to our home. The first detailed cross-section of a galaxy broadly similar to the Milky Way, published today, reveals that our galaxy evolved gradually, instead of being the result of a violent mash-up. The finding throws the origin story of our home into doubt.

The galaxy, dubbed UGC 10738, turns out to have distinct ‘thick’ and ‘thin’ discs similar to those of the Milky Way. This suggests, contrary to previous theories, that such structures are not the result of a rare long-ago collision with a smaller galaxy. They appear to be the product of more peaceful change.

And that is a game-changer. It means that our spiral galaxy home isn’t the product of a freak accident. Instead, it is typical.

The finding w...

Fat around the Heart Linked to Increased Risk of Heart Failure

Having excess pericardial fat — fat aro-und the heart — increases the risk of developing heart failure, especially in women, according to new Mount Sinai research.

Women with high amounts of pericardial fat are twice as likely to develop heart failure, while men are 50 percent more likely, according to the study, published in the May 24 online issue of the Journal of the American College of Cardiology. It is the largest study to identify the link between pericardial fat and heart failure, which could potentially lead to early intervention and heart disease prevention.

“For nearly two decades we have known that obesity, based on simple measurement of height and weight, can double one’s risk of heart failure, but now, we have gone a step further by using imaging technology to show...

Generating Electricity from Heat using the Spin Seebeck Device

Thermoelectric (TE) conversion offers a carbon-free power generation from geothermal, waste, body or solar heat, and shows promise to be the next-generation energy conversion technology. At the core of such TE conversion, there lies an all solid-state thermoelectric device which enables energy conversion without the emission of noise, vibrations, or pollutants. To this, a POSTECH research team proposed a way to design the next-generation thermoelectric device that exhibits remarkably simple manufacturing process and structure compared to the conventional ones, while displaying improved energy conversion efficiency using the spin Seebeck effect (SSE).

A POSTECH joint research team — led by Professor Hyungyu Jin and Ph.D...

36 Dwarf Galaxies had simultaneous ‘Baby Boom’ of New Stars

Surprising finding challenges current theories on how galaxies grow. Three dozen dwarf galaxies far from each other had a simultaneous “baby boom” of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe.

Galaxies more than 1 million light-years apart should have completely independent lives in terms of when they give birth to new stars...
