Lung cancer causes more deaths in the U.S. than the next three most common cancers - colon, breast, and pancreatic - combined, for a simple reason: poor detection.

You can be living your life with no symptoms while it is metastasizing uncontrollably and it reaches the point of no return. 

A  research team has revealed conflicting climate change patterns between the middle latitude areas of the Northern and Southern Hemispheres in relation to glacial and interglacial cycles which have been a puzzle for the past 60 years.

Their study collected samples from the stalagmites and flowstones in limestone caves which are called 'hard disks' containing the past climate change data and revealed how much they grew in which eras through isotope analysis and age dating, and traced the past climate changes by applying them to global climate change over 550,000 years.

Anesthesia works, we know that. Properly done, patients can be temporarily rendered completely unresponsive during surgery and then wake up again, with their memories and skills intact. Improperly done, of course, can be very bad.

But little is understood about the processes used by structurally normal brains to navigate from unconsciousness back to consciousness. Anesthesia leads the world in retracted papers.

Previous research has shown that the anesthetized brain is not "silent" under surgical levels of anesthesia but experiences certain patterns of activity, and it spontaneously changes its activity patterns over time.

In a marked cemetery northwest of Lake Baikal, a skeleton was found, buried ceremoniously with a nephrite disk and four arrowheads, one of which was broken and found in the eye socket. An arrow in the eye? That's no accident.

After radiocarbon dating and analysis, it was determined the individual was a 35-40 year-old male from the early Bronze Age, between 2406 and 1981 B.C.

Unlike most hunter-gatherer societies of the Bronze Age, the people of the Baikal region of modern Siberia (Russia) respected their dead with formal graves. This particular specimen was so unique that bioarchaeologist Angela Lieverse traveled across the world just to bring it back to the Canadian Light Source synchrotron for examination.

New observations made using NASA's Hubble Space Telescope show that dwarf galaxies are responsible for forming a large proportion of the universe's stars.

The result supports a decade-long investigation into whether there is a link between a galaxy's mass and its star-forming activity, and helps paint a consistent picture of how galaxies grew and evolved 3.5 to 6 billion years after the beginning of the universe. 

Cancer care has had lots of known side effects but one goes less discussed - the "financial toxicity", which is the expense, anxiety and loss of confidence confronting those who face large, unpredictable costs, often compounded by decreased ability to work.

Writing in Cancer, a team of University of Chicago cancer specialists describe the first tool to measure a patient's risk for, and ability to tolerate, financial stress. The researchers named their patient-reported outcome measure COST (COmprehensive Score for financial Toxicity) and uses
11 questions, assembled and refined from conversations with more than 150 patients with advanced cancer.
