There has long been debate about the role of Earth’s orbit in driving global climate cycles. As most people know, 90,000 of every 100,000 years have been ice ages in patterns.

Scientists have long been aware that the waxing and waning of massive Northern Hemisphere ice sheets results from changes in the geometry of Earth’s orbit around the Sun. A new study has been able to pinpoint exactly how the tilting and wobbling of the Earth as it orbits around the Sun has influenced the melting of ice sheets in the Northern Hemisphere over the past 2 million years.

Cyanobacteria, also known as blue-green algae, can produce toxins and deplete lakes of oxygen when they die.  It can be dangerous for both pets and people. In August 2014, nearly half a million people in the Toledo area were without tap water for nearly three days due to contaminated drinking water. A type of blue-green algae, Microcystis, had produced particularly high levels of the liver toxin microcystin (MC) in Lake Erie.

Since the nutrient phosphorus is an important nutrient for these algae, and environmentalists and the politicians they influence don't understand biological systems thinking, they have made efforts to reduce phosphorus levels and inhibit the growth of cyanobacteria.

The common belief is that women who have twins are more fertile but what does the science say?

A detailed analysis of more than 100,000 births to women born between 1700 and 1899, published on 24 May 2022 in Nature Communications, found the answer is no.

Analysis of the offspring of twins shows that they are not exceptionally fertile when compared to the rest of the population. In addition, without refined statistical analysis, previous studies on the subject could not determine whether women have twins more often because they frequently release more than one egg during ovulation, or whether it is the multiplication of pregnancies that increases their chances.

"All The President's Men" inspired young people to rush to journalism while "Mad Men" caused enrollment in advertising courses to surge and "Top Gun led to more Navy recruits.

Film and television shapes young minds and marketers know it. A whole generation of people will believe a show like "The Offer" is a history of "The Godfather" film the same way some believe "Food Inc" is science; because it is on a screen. Yet trends have changed as fashions have. 'Stewardess' is out of the lexicon while 'Congressman' is still in.

A new study finds that hugging a romantic partner can prevent the acute stress response of female bodies.

Women who embrace their romantic partner prior to undergoing a stressful experience had lower levels of the stress hormone cortisol in saliva compared to women who did not embrace their partner. No effect was found for men.

Some papers have claimed that massages, embraces combined with hand-holding, and embraces combined with affectionate communication can reduce signs of stress in women but those usually do not include men nor any effects of a brief embrace.

At the centere of our galaxy, the Milky Way, there exists what must be a black hole. But detecting it has been challenging because of the cosmic dust around it.

Now, for the first time, a group of radio antennas knows as the Event Horizon Telescope Collaboration have unveiled the first image of the supermassive black hole four million times more massive than our Sun.

known as Sagittarius A* (Sgr A*, pronounced "sadge-ay-star") it obviously can't be seen, that is built into the black hole name, but it can be inferred thanks to a dark central region (called a “shadow”) surrounded by a bright ring-like structure. The new view captures light bent by the powerful gravity of the black hole.
