In recent years, the notion of an insect apocalypse has become a hot topic in the conservation science community and has captured the public’s attention. Scientists who warn that this catastrophe is unfolding assert that arthropods – a large category of invertebrates that includes insects – are rapidly declining, perhaps signaling a general collapse of ecosystems across the world.

As time passes, our fertility declines and our bodies start to fail. These natural changes are what we call ageing.

In recent decades, we’ve come leaps and bounds in treating and preventing some of the world’s leading age-related diseases, such as coronary heart disease, dementia and Alzheimer’s disease.

But some research takes an entirely unique view on the role of science in easing the burden of aging, focusing instead on trying to prevent it, or drastically slow it down. This may seem like an idea reserved mainly for cranks and science fiction writers, but it’s not.

Consumers have been so saturated with vague marketing claims that nearly 50 percent can't correctly identify what is claimed to be a "healthier" option on packages.

That sounds bad, except buying whole grain or white bread or fancy crackers are not making any difference in health anyway.

The Atacama Large Millimeter/submillimeter Array (ALMA) in Chile recently took a census of stellar eggs in the constellation Taurus and their evolution state in order to better understand how and when a stellar embryo transforms to a baby star deep inside a gaseous egg. 

They also found a bipolar outflow, a pair of gas streams - that could be telltale evidence of a truly newborn star.

Life developed when there was no oxygen on earth. It was an anoxic environment dominated by bacteria, who instead of oxidation and reduction, as our mitochondria do to produce energy, probably extracted various substances by means of fermentation.

But there has long been another possibility; a kind of “oxygen-free respiration” hinted at in studies on primordial microbes that are still found in anoxic habitats today. There have been found genes in microbes that perhaps encode for a primordial respiration enzyme.

Yet proving the existence of this respiratory enzyme and isolating it requires time and effort. The complex is fragile and often fell apart during attempts to isolate it from the membrane. 

It’s a common assumption that exercise in older people is difficult and dangerous, so it’s perhaps best avoided. But this is often not the case – even if these ideas are ingrained in society. Research has repeatedly shown that exercise in older adults is linked with lower disease risk, reduced risk of falls, and better overall health.

Compared to cisgender people (gender identity corresponds to their sex), an analysis of over 600,000 adults finds transgender and gender-diverse adults are three to six times more likely to be diagnosed as autistic. 

The findings are simply exploratory and about co-occurrence between gender identity and autism diagnoses, they cannot inform or suggest causal links.  These correlations have confounders.

Egyptian coffins and mummy cases have been found covered in a mysterious 'black goo'. What is this goo made from and what can it reveal about Egyptian funerary practice? The British Museum's Kate Fulcher has detailed answers but you can read a summary below.

Djedkhonsiu-ef-ankh died almost 3,000 years ago in ancient Egypt. He was a priest in the temple of Amun at Karnak, where he was an ‘Opener of the Doors of Heaven’ - permitted to open the temple sanctuary which contained the image of their deity.

An annotated list of 219 pathogens that infect plants in Brazil, including many agriculturally important species, shows just how precarious things can be when it comes to maintaining an affordable, sustainable food supply.
