Surveying the genetic battlefield to uncover the rules of rapid evolution‎

The Malik Lab thrives on competition. But for HHMI investigator Harmit Malik and his team at the Fred Hutchinson Cancer Center, it's the genomes—not the people—that are in conflict. The lab studies rapid evolution—the genetic changes that happen in a species over a few generations rather than thousands of years. These fast changes are often fueled by genetic conflicts—competitions between different entities trying to maximize their success at the expense of another.

Pollution from human-generated waste in marine ecosystems has reached critical levels, with cigarette butts (CBs) among the most persistent and harmful pollutants. Globally, an estimated 4.5 trillion cigarette butts are discarded annually, making them the most common type of litter on beaches over the past three decades.

Habitat explains Finnish animal distributions better than climate, study finds‎

Researchers at the University of Helsinki wanted to understand which is the dominant factor for species occurrence and abundance: the climate or habitat-related variables, such as their natural state and the share of land shaped by human activity. Solutions to mitigate biodiversity loss depend on the answer to this question.

Power cuts and sleep: Students link load shedding to anxiety, disrupted rest and lower grades‎

South Africa endured its worst year of load shedding (scheduled power cuts by the country's utility, Eskom) in 2023. The power went off on 335 of the year's 365 days, often several times a day. Since then, the country has gone more than a year and a half without these planned power cuts.
