Late-Stage Pandemic Is Messing With Your Brain2d
I first became aware that I was losing my mind in late December. It was a Friday night, the start of my 40-somethingth pandemic weekend: Hours and hours with no work to distract me, and outside temperatures prohibitive of anything other than staying in. I couldn't for the life of me figure out how to fill the time. "What did I used to … do on weekends?" I asked my boyfriend, like a soap-opera amn

Research offers insights on how night shift work increases cancer risk2d
A recently published study offers new clues as to why night shift workers are at increased risk of developing certain types of cancer compared to those who work regular daytime hours. Findings suggest that night shifts disrupt natural 24-hour rhythms in the activity of certain cancer-related genes, making night shift workers more vulnerable to DNA damage while also causing the body's DNA repair me
Microscopic wormholes possible in theory18h
Wormholes play a key role in many science fiction films—often as a shortcut between two distant points in space. In physics, however, these tunnels in spacetime have remained purely hypothetical.

A conserved Ctp1/CtIP C-terminal peptide stimulates Mre11 endonuclease activity [Biochemistry]20h
The Mre11-Rad50-Nbs1 complex (MRN) is important for repairing DNA double-strand breaks (DSBs) by homologous recombination (HR). The endonuclease activity of MRN is critical for resecting 5′-ended DNA strands at DSB ends, producing 3′-ended single-strand DNA, a prerequisite for HR. This endonuclease activity is stimulated by Ctp1, the Schizosaccharomyces pombe homolog…
Improved photosynthetic capacity and photosystem I oxidation via heterologous metabolism engineering in cyanobacteria [Plant Biology]20h
Cyanobacteria must prevent imbalances between absorbed light energy (source) and the metabolic capacity (sink) to utilize it to protect their photosynthetic apparatus against damage.

An epic walk: 15 million years needed for dinosaurs to get from South America to Greenland21h
For the first time, two researchers have accurately dated the arrival of the first herbivorous dinosaurs in East Greenland. Their results demonstrate that it took the dinosaurs 15 million years to migrate from the southern hemisphere, as a consequence of being slowed down by extreme climatic conditions. Their long walk was only possible because as CO2 levels dropped suddenly, the Earth's climate b
Head injury 25 years later — Penn study finds increased risk of dementia1d
New research at Penn shows that a single head injury could lead to dementia later in life. This risk further increases as the number of head injuries sustained by an individual increases. The findings also suggest stronger associations of head injury with risk of dementia among women compared to among men and among white as compared to among Black populations.
UCLA-led study reveals 'hidden costs' of being Black in the US1d

Recyclable bioplastic membrane to clear oil spills from water18h
Polymer scientists from the University of Groningen and NHL Stenden University of Applied Sciences, both in the Netherlands, have developed a polymer membrane from biobased malic acid. It is a superamphiphilic vitrimer epoxy resin membrane that can be used to separate water and oil. This membrane is fully recyclable. When the pores are blocked by foulants, it can be depolymerized, cleaned and subs
X marks the spot: How genes on the sex chromosomes are controlled1d
Because human females have two X chromosomes and males have one X and one Y, somatic cells have special mechanisms that keep expression levels of genes on the X chromosome the same between both sexes. This process is called dosage compensation and has been extensively studied in the fruit fly Drosophila. Now, researchers at the University of Tsukuba (UT) continued work with Drosophila to show that

How scientists found rare fireball meteorite pieces on a driveway—and what they can teach us1h
As people in the UK were settling down to watch the late evening news on February 28, a fresh news story, quite literally, appeared in the night sky. A large and very bright fireball was seen over southern England and northern France at 21:54 GMT. It was recorded by many doorbell webcams, so it was a very well-observed fireball. More importantly, it was also captured by the automated cameras of th
The most recent volcanic activity on the moon? Just 100 million years ago2h
Regions of the moon known as irregular mare patches—formed by magma cooling from a volcanic eruption—have almost no big craters, indicating that they must be relatively young. By studying the distribution of craters within them, we can estimate when these regions were formed: no more than 100 million years ago.
How do you get power into your lunar base? With a tower of concrete several kilometers high2h
It sounds like science fiction, but building an enormous tower several kilometers high on the lunar surface may be the best way to harness solar energy for long-term lunar exploration. Such towers would raise solar panels above obstructing geological features on the lunar surface, and expand the surface area available for power generation.
