Researchers plan for new centre to explore refreezing the poles, sucking out CO₂ and ocean greening.

Cosmologists have a new guess about why the universe is expanding outward faster than data says it ought to.

The hypothesis, according to research first shared on the preprint server ArXiv in November, goes as follows: When the universe was just a mere 100,000 years old, a mysterious energy field that scientists are calling “early dark energy” formed, rapidly pushing the still-forming cosmos outward even faster than before.

Another 100,000 years after that, the research suggests, the strange energy field faded away — and left the young, accelerated universe to its own devices.

Where did Groot come from? In reality, he came from the imaginations of Jack Kirby, Dick Ayers, and Stan Lee. In the Guardians of the Galaxy movie, he came from another planet. In this essay, he came from the stuff in your yard. We’ll see which plants might have evolved, over time, to become the world’s most beloved tree-man. Warning: Major spoilers for the movie after this point!

Deforestation is a recurrent problem in practically the entire world. Recovering the damage done in recent years as a result of large industries and land depredated for agriculture and livestock is a difficult task. But Thailand believes it has found the best solution, fast, simple and effective.

“It was a huge surprise, we didn’t expect to find so many melanoma cancer cell markers in blood exosomes,” explains Hubert Girault, who heads up the Laboratory of Physical and Analytical Electrochemistry at EPFL Valais Wallis. Professor Girault and his team made the discovery almost by accident. Their findings, which have been published in the journal Chem, offer insight into how cancer cells communicate with each other and send information around the body.

All biological cells excrete exosomes, microscopic spheres or vesicles that are less than 100 nanometers in size and contain a wealth of information in the form of nucleic acids, proteins and markers. Exosomes perform cell-to-cell signaling, conveying information between cells. Under the supervision of Senior Scientist Dr. Horst Pick, EPFL doctoral assistant Yingdi Zhu used cell culture and mass spectrometry to isolate melanoma cancer cell exosomes. She was able to identify cancer cell markers in exosomes for each stage of melanoma growth.

When analyzing the blood exosomes of melanoma patients, the researchers were surprised to discover large quantities of cancer cell markers. The blood collects and transports all the exosomes that the body generates. While healthy cells usually produce exosomes in small quantities, cancer cells produce many more. But it was previously thought that these would be so diluted in the blood that they would be hard to detect. For Professor Girault, the discovery of large quantities of cancer cell markers in blood exosomes raises numerous questions about signaling between cancer cells, which until now were not thought to communicate over longer distances within the body.

Enough gold, uranium and other heavy elements about equal in mass to all of Earth’s oceans likely came to the solar system from the collision of two neutron stars billions of years ago, a new study finds.

If the same event were to happen today, the light from the explosion would outshine the entire night sky, and potentially prove disastrous for life on Earth, according to the new study’s researchers.

Recent findings have suggested that much of the gold and other elements heavier than iron on the periodic table was born in the catastrophic aftermath of colliding neutron stars, which are the ultradense cores of stars left behind after supernova explosions.
