Way too many batteries still end up in a landfill, though it depends on the type. While 90% of lead acid batteries are recycled, experts estimate that only about 5% of lithium-ion batteries currently enter a recycling stream. Many more lurk in drawers or end up in the trash. That’s a problem.

Why you shouldn’t throw batteries in the trash

Lithium-ion batteries can cause fires when exposed to heat, mechanical stress, or other waste materials. Once exposed, the elements contained in the batteries could leach into the environment and contaminate the soil and groundwater. While this shouldn’t present an issue at a well-managed domestic facility, exported trash might end up at a more lenient landfill. Richa et al. note that “the greater risk is loss of valuable materials.”

It was thought that spongy bone in woodpeckers’ heads cushioned their brains from hard knocks, but in fact their skulls are stiff like a hammer.

The entirely theoretical cloud of icy space debris marks the frontiers of our solar system.

The Oort cloud represents the very edges of our solar system. The thinly dispersed collection of icy material starts roughly 200 times farther away from the sun than Pluto and stretches halfway to our sun’s nearest starry neighbor, Alpha Centauri. We know so little about it that its very existence is theoretical — the material that makes up this cloud has never been glimpsed by even our most powerful telescopes, except when some of it breaks free.

“For the foreseeable future, the bodies in the Oort cloud are too far away to be directly imaged,” says a spokesperson from NASA. “They are small, faint, and moving slowly.”

A geological mystery is unfolding far beneath our feet, and it may shed light on the life-sustaining magnetic field that extends far above our heads.

Each year, the solid-iron inner core at the heart of our planet expands by about a millimeter as the Earth’s nether regions cool and solidify. According to a recent study, one side appears to be growing faster — but scientists don’t know why.

This phenomenon likely dates back to the inner core’s creation, between 1.5 billion and half a billion years ago. At this point, after billions of years of cooling, the Earth’s fiery interior finally lost enough heat to begin an ongoing process of crystallization. Now, as the outer core’s molten iron loses heat, it crystallizes to become the newest layer of the inner core.

An international team of astronomers has conducted an astrometric and photometric wide-field study of the open cluster Messier 37. As a result, the researchers completed a comprehensive catalog of more than 200,000 sources in the field of Messier 37 and identified the hottest white dwarf candidate members of this cluster. The study was detailed in a paper published July 7 on arXiv.org.

Open clusters (OCs), formed from the same giant molecular cloud, are groups of stars loosely gravitationally bound to each other. So far, more than 1,000 of them have been discovered in the Milky Way, and scientists are still looking for more, hoping to find a variety of these stellar groupings. Studying OCs in detail could be crucial for improving our understanding of the formation and evolution of our galaxy.

Messier 37 (or M37, also known as NGC 2099) is the brightest and richest Galactic OC in the constellation Auriga, located at a distance of about 4,500 light years. The cluster has a radius of at least 10 light years and a total mass of some 1,500 solar masses. The age of Messier 37 is estimated to be between 400 and 550 million years, while its metallicity is at a level of 0.02–0.08.

From endpoint fluorescence to melting curve analysis.

Today’s research on somatic, genetic and epigenetic variation in eukaryotic cells requires fast, accurate and cost-effective methods for screening large numbers of samples or loci in parallel. Variations identified by genomic sequencing or array studies need to be subsequently confirmed and validated.

Powering plant growth with solar panels instead of photosynthesis could be a more efficient way of using the Sun’s energy for food. But it’s not all good news.

Astronomers have discovered a gargantuan galaxy. Alcyoneus is a massive radio galaxy 3 billion light-years away that extend 5 megaparsecs into space.
