Medical News Today: Is amyl nitrite safe?

People often take amyl nitrite, commonly referred to as poppers, for the euphoric effects. However, taking poppers can have serious health consequences and may be fatal.

Medical News Today: Spray gel could reduce cancer spread after surgery

A 'sprayable gel' embedded with nanoparticles carrying drugs that boost immunity controlled tumor recurrence at surgery site and at distant sites in mice.

Medical News Today: IBD increases prostate cancer risk by fivefold

According to a new study, inflammatory bowel disease increases the risk of developing prostate cancer. This finding opens up a challenging clinical debate.

How the brain tells you to scratch that itch

It's a maddening cycle that has affected us all: it starts with an itch that triggers scratching, but scratching only makes the itchiness worse. Now, researchers have revealed the brain mechanism driving this uncontrollable itch-scratching feedback loop. Researchers showed that the activity of a small subset of neurons, located in a deep brain region called the periaqueductal gray, tracks itch-evoked scratching behavior in mice.

Exercise-induced hormone irisin triggers bone remodeling in mice

Exercise has been touted to build bone mass, but exactly how it actually accomplishes this is a matter of debate. Now, researchers show that an exercise-induced hormone activates cells that are critical for bone remodeling in mice. A study identifies a receptor for irisin, an exercise hormone, and shows that irisin impacts sclerostin in mice, a major cellular regulator of bone structure in humans.

Neanderthal genes give clues to human brain evolution

A distinctive feature of modern humans is our round (globular) skulls and brains. Researchers report that present-day humans who carry particular Neanderthal DNA fragments have heads that are slightly less rounded, revealing genetic clues to the evolution of modern brain shape and function.

Novel mechanisms of dengue and Zika virus infections and link to microcephaly

New insights into how dengue and Zika viruses cause disease reveal strategies the viruses use to successfully infect their host and a link to microcephaly.

CRISPR joins battle of the bulge, fights obesity without edits to genome

A weighty new study shows that CRISPR therapies can cut fat without cutting DNA. Researchers describe how a modified version of CRISPR was used to ramp up the activity of certain genes and prevent severe obesity in mice with genetic mutations that predispose them to extreme weight gain. Importantly, the researchers achieved long-lasting weight control without making a single edit to the genome.

Medical News Today: 19 natural remedies for a headache

Headaches are a common complaint. Fortunately, there are many natural and home remedies a person can use to get relief. Learn about them here.

Megacity traffic soot contributes to global warming

Soot from road traffic in emerging countries can reach high altitudes, where it can be transported over long distances and thus contributes to global warming. The reduction of pollutants from road traffic such as soot particles from diesel cars should therefore have high priority in order to both protect the health of the population in the growing conurbations of emerging countries and reduce global warming.

Data use draining your battery? Tiny device to speed up memory while also saving power

Millions of new memory cells could be part of a computer chip and save power for smart devices, thanks to the discovery of a previously unobserved functionality in a super thin material.
