Scientists discover shared genetic foundations between musical rhythm and human language

[Genetic] variants associated with higher likelihood of rhythm impairments tended to also be associated with a higher likelihood of dyslexia. The reverse was also the case: [variants] associated with more accurate musical rhythm skills co-occurred with genes linked to higher performance on language and reading tests[.]

Scientists find humans age dramatically in two bursts – at 44, then 60

The first wave of changes included molecules linked to cardiovascular disease and the ability to metabolise caffeine, alcohol and lipids. The second wave of changes included molecules involved in immune regulation, carbohydrate metabolism and kidney function. Molecules linked to skin and muscle ageing changed at both time points.

The redpoll finch saga: How two bird species just became one

[The] hoary redpoll finch, a small, plump bird commonly found in the Arctic, will be reclassified as the same species as the common redpoll finch, a smaller bird found in similar habitats. This announcement came as a direct result of a CU Boulder-led study which found that, despite their different looks, very few genetic differences exist between the two types of birds.

Analysis shows butterfly and moth genomes are mostly unchanged despite 250 million years of evolution

The team found not only were chromosomes incredibly stable, but the order of genes within them was too. […] However, researchers uncovered a rare subset of species such as the blue butterflies—Lysandra—and the group containing cabbage white butterflies—Pieris—that underwent extensive chromosome reshuffling[.]

Moth found in West London is a new species from Australia

In 2021 an amateur moth-er living in Ealing, West London, opened her moth trap to find something she didn’t recognise. […] Detailed analysis of the moth, including both morphology and DNA, revealed that the insect was indeed a new species to science, but one that is native to Western Australia rather than Ealing.

Crispr gene editing shown to permanently lower high cholesterol

In a small initial test in people, researchers have shown that a single infusion of a novel gene-editing treatment can reduce cholesterol, the fatty substance that clogs and hardens arteries over time.

Cause and Cure Discovered for Common Type of High Blood Pressure

The cause is a tiny benign nodule, present in one-in-twenty people with hypertension. The nodule produces a hormone, aldosterone, that controls how much salt is in the body. […] The researchers also discovered that this form of hypertension could be cured by unilateral adrenalectomy – removing one of the two adrenal glands.

Genetic determinants of liking and intake of coffee and other bitter foods and beverages - Scientific Reports

In summary, our genetic analysis suggests the psychostimulant effects of caffeine outweighs the bitterness of caffeine. A greater preference for caffeine based on genetic differences in the physiological effects of caffeine leads to a stronger preference for the taste/smell of coffee and dark chocolate. Similarly, greater sensitivity to the adverse physiological effects of caffeine was associated with avoiding the taste of coffee.
