Researchers developed a way to attach freeze-dried sperm to paper, allowing it to be transported easily and safely — even through the mail. Healthy mouse offspring have been produced from the freeze-dried sperm’s DNA.
NASA’s Perseverance rover came up empty-handed after its first sampling attempt on Mars. NASA is investigating why Perseverance couldn’t retrieve a sample from its first drill hole.
Researchers discovered how stress hormones impact neuroplasticity and cilia function in the brain. The findings could help researchers better understand chronic stress and its role in mental health.
A review of Curiosity rover data suggested that Gale Crater may be filled with wind-blown sediment, rather than lake sediment, as was previously believed. The finding could mean the area was less likely to host life than scientists thought.
Researchers identified a new species of beetle with distinct body markings from a spectacularly well-preserved fossil. The beetle was named Attenborough’s Beauty, after naturalist Sir David Attenborough.
Scientists developed a new type of micrometer-scale microgel that can help the body grow new blood vessels. The microgel could be used to speed healing in regenerative therapies.
The Intergovernmental Panel on Climate Change released a bombshell report concluding that human activity is responsible for hotter temperatures and extreme weather events. Slowing the trend is possible but requires decisive action.
Researchers discovered that wrinkles in venomous snakes’ teeth — which help attach teeth to the jaw — developed into venom grooves, giving snakes their distinctive, deadly fangs.
The Perseids meteor shower peaks between midnight on August 11 and sunrise on August 13. The brightest meteor shower of the year will be visible with the naked eye in dark places.
