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.

Every egg cell and sperm cell depends on meiosis, a tightly choreographed process in which chromosomes find their partners, exchange genetic material, and then divide. When meiosis goes awry in humans, the consequences can include infertility, miscarriage, and birth defects. A new study from the Stowers Institute for Medical Research, published in Science Advances, shows that the molecular machinery guiding this process is more widely shared across animals than expected, and more flexible. The surprise was that familiar-looking parts were not always doing the same jobs, revealing an unexpected flexibility in how meiosis works across evolution.

Gill) When we look up at Mars, many millions of miles away, it's inspiring to think that someone may be looking back at us – not any heat-ray-equipped aliens, thankfully, but one of humanity's greatest accomplishments: NASA's Perseverance rover. In July of 2020, the affectionately nicknamed Percy left Earth forever in a bright flash of hope during some of modern history's darkest days. It, and we, have come a long way since then.

Perseverance is a product of its predecessors.

Using more than one type of app, including both mainstream sites such as Tinder or Hinge and gay sites like Grindr, could lead to lower levels of anxiety among gay men who use mobile dating platforms. The Flinders University study, published in Psychology & Sexuality, is one of the first efforts to compare users of different dating app types and sexual orientation with mental health and wellbeing outcomes.

VLSS J0318.9+5755, a strange, musical-note-shaped radio source hiding behind the Milky Way’s dusty disk, has turned out to be the glowing remains of an ancient black hole outburst inside a massive, colliding galaxy cluster. This composite image of the Treble Clef and its galaxy cluster contains X-rays from Chandra and eROSITA, radio data from LOFAR, and infrared data from UKIRT.
