The human body can predict the timing of regular meals, according to a new study from the University of Surrey. The research team also found that daily blood glucose rhythms may be driven not only by meal timing but by meal size.   In the first study of its kind, researchers from Surrey, led by Professor Jonathan Johnston, investigated if the human circadian system anticipates large meals. Circadian rhythms/systems are physiological changes, including metabolic, that follow a 24-hour cycle and are usually synchronised to environmental signals, such as light and dark cycles.   Previous ...

In a new study, an international team of astrophysicists has discovered several mysterious objects hiding in images from the James Webb Space Telescope: six potential galaxies that emerged so early in the universe’s history and are so massive they should not be possible under current cosmological theory. Each of the candidate galaxies may have existed at the dawn of the universe roughly 500 to 700 million years after the Big Bang, or more than 13 billion years ago. They’re also gigantic, containing almost as many stars as the modern-day Milky Way Galaxy. “It’s ...

The world’s forests are losing their ability to absorb carbon due to increasingly ‘unstable’ conditions caused by humans, a landmark study has found. Dramatic changes to forests, and other habitats that store carbon in plants and soils, are becoming more likely in some regions across Earth, with less carbon consistently absorbed by the ‘land carbon sink’ provided by trees, soil and plants, according to scientists writing in Nature. The short-term impacts of rising temperatures, ...

Why is "junk DNA" not deleted from the original genome over millions of years of evolution? A new model offers an explanation for the huge variety of sizes of DNA in nature Unlike "junk email" that is immediately deleted from the email box, "junk DNA" continues to exist in living creatures in nature such as bacteria, insects, and even mammals such as humans, alongside the original genome and thus the genome grows throughout evolution. The researchers' explanation: the "junk DNA" hides in functional areas, thus deletions are likely to damage the functional ...

People are occasionally exposed to potentially harmful substances in the environment or through their diets or habits. For example, a compound found in cigarette and industrial smoke, benzo(a)pyrene (BaP), is known to damage DNA. Now, researchers reporting in ACS Central Science have mapped these effects — down to the single-nucleotide level — for the first time in human lung cells after BaP exposure. They say that this technique could help predict exposures that lead to cancers. When BaP gets into a person’s body and is metabolized, it can turn into a new compound, or metabolite, that irreversibly attaches to one ...

Although many measures are in place to prevent contamination, pollutants, such as mercury and lead, can still end up in the environment.
