Climate change: CO2 was not a problem before 1965 but we are suffering the consequences | Science | New

[ad_1] Climate researchers in Texas believe that the Earth existed in a "low-carbon environment" until the mid-1960s. A study published by the Texas College of Geosciences at A & M University's Texas has revealed that atmospheric CO2 levels do not exceed 320 parts per million – a record that has been unmatched for 2.5 million … Read more

An amateur astronomer spots a second interstellar visitor

[ad_1] TYears ago 'Oumuamua, an asteroid from interstellar space, visited the solar system. It was the first body of this type observed, but now a second extraterrestrial object (shown next) is in the line of sight of astronomers. 2I / Borisov is a comet rather than an asteroid. The difference is that, warmed by sunlight, … Read more

Do the gamma streams really reach superluminal speeds? | Astronomy

[ad_1] High-speed particle jets from gamma-ray bursts may exceed the speed of light in surrounding gas clouds, but they do not violate Einstein's theory of relativity, according to a team of astrophysicists at Michigan Technological University and the College of Charleston. Impression of an artist on a jet of particles emanating from a black hole … Read more

a black hole rips an unhappy star

[ad_1] By Joey Routlette WASHINGTON, Sept. 26 (Reuters) – Scientists have captured the vision of a colossal black hole violently tearing a doomed star, illustrating an extraordinary and chaotic cosmic event from start to finish for the first time with the help of NASA planetary hunting telescope. The exploration satellite orbiting the arbitration satellite transits … Read more

Ultrasonic imaging of gene expression in mammalian cells

[ad_1] Survey of mammalian cells Live cell imaging allows us to observe cellular processes in real time. Most methods rely on light and the low penetration of light into the tissue limits the application. Ultrasound penetrates the tissues and ultrasonic cell reporters have been developed recently. These reporters are air – filled protein structures that … Read more

Continuous accumulation of plant diversity through habitat connectivity over an 18 year experience

[ad_1] Habitat connectivity improves diversity Fragmentation of ecosystems results in loss of biodiversity in the remaining habitat patches, but maintaining communication corridors can reduce these losses. Using long-term data from a vast replicated experiment, Damschen et al. show quantitatively how these losses are reduced. In their pine savanna system, corridors reduced the probability of plant … Read more
