Globalised economy making water, energy and land insecurity worse: study

Delivering healthcare services online can cut costs for patients, but not necessarily for providers, according to a new study. University of Queensland researcher Centaine Snoswell and colleagues reviewed telehealth to determine whether the introduction of video appointments and remote patient monitoring reduced the financial burden on the healthcare system.

Like its human counterparts, a young star is cute but prone to temper flares-only a star's are lethal. A flare from a star can incinerate everything around it, including the atmospheres of any nearby planets starting to form.

Ribosomes are small "factories" in which proteins are assembled according to genetic construction plans. The maturation of ribosomes, of which every human cell contains up to a million, is a complicated, multi-phase process. Now, with the aid of cryo-electron microscopy, scientists from Heidelberg University and Ludwig-Maximilians-Universität München have been able to clarify an important step in ribosomal formation. These "protein factories" consist of two ribosomal subunits and the scientists have shown that the smaller one "peels out" of a precursor complex and does not break off en bloc, as was so far assumed. The findings were published in the journal "Science".

As early as 1975, biologists discovered that the protein-coding parts of the chimpanzee and human genomes are more than 99 percent identical. Yet, chimpanzees and humans are clearly different in significant ways.

For much of Earth's four and a half billion years, the planet was barren and inhospitable; it wasn't until the world acquired its blanket of oxygen that multicellular life could really get going. But scientists are still trying to understand exactly how-and why-our planet got this beautifully oxygenated atmosphere.

A team of researchers from Freie Universität Berlin and ETH Zurich studied if antifungal and antibiotic resistance emerge faster than in the past
