My uneducated guess is that this is mostly an effect of other risky behavior (more prevalent among tattooed people) that they’ve not accounted for, such as alcohol consumption.
Possible association between tattoos and lymphoma revealed
“After taking into account other relevant factors, such as smoking and age, we found that the risk of developing lymphoma was 21 percent higher among those who were tattooed. It is important to remember that lymphoma is a rare disease and that our results apply at the group level. The results now need to be verified and investigated further in other studies and such research is ongoing”, says Christel Nielsen.

Urban great tits have paler plumage than their forest-living relatives
The distinctive yellow color in the great tit's feathers comes from pigments called carotenoids which are found in food sources. The great tits get these nutrients from the insects they eat, who, in turn get carotenoids from the plants they feed on. This new research suggests that urban great tits are not able to consume as many carotenoids from their food as their countryside counterparts, and possibly fewer than they might need to stay as healthy.

Urban great tits less stressed than their countryside cousins, finds study
"The great tit's high cognitive capacity means it is highly adaptable, and urban great tits seem to have adapted so well to the new environment that they are not stressed by high population density. Another possible explanation is that it was the most intelligent and most flexible individuals who succeeded in colonizing urban environments in the first place," says Anders Brodin, biologist at Lund University.

Climate change has increased diversity of butterflies in Sweden and Finland, may have major ecosystem consequences
New research shows that butterflies have expanded their ranges over the past 120 years to cope with a warmer climate in Sweden and Finland. Although driven by a warmer climate, range expansions have also been influenced by human land use and vary according to species thermal tolerances and habitat preferences.

Study shows bird feeding helps small birds fight infection
When the birds were exposed to a simulated infection, all the birds had essentially the same temperature during a fever. Instead of conserving energy to survive the winter, the birds without access to extra food were forced to use more energy in order to raise their body temperature high enough to battle infection.
