Increasing riverine heat influx triggers Arctic sea ice decline and oceanic and atmospheric warming
Arctic river discharge increased over the last several decades, conveying heat and freshwater into the Arctic Ocean and likely affecting regional sea ice and the ocean heat budget. However, until now, there have been only limited assessments of riverine heat impacts. Here, we adopted a synthesis of a pan-Arctic sea ice–ocean model and a land surface model to quantify impacts of river heat on the

Has the hidden matter of the universe been discovered?
Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d'Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data.

Photopharmacology — light-gated control of the cytoskeleton
Ludwig-Maximilians-Universitaet (LMU) in Munich researchers have developed photoresponsive derivatives of the anticancer drug Taxol®, which allow light-based control of cytoskeleton dynamics in neurons. The agents can optically pattern cell division and may elucidate how Taxol acts.

Paleogenomics — the prehistory of modern dogs
An international team of scientists has used ancient DNA samples to elucidate the population history of dogs. The results show that dogs had already diverged into at least five distinct lineages by about 11,000 years ago and that their early population history only partially reflects that of human groups.

Down Syndrome-associated gene suppresses age-related corneal clouding
Down syndrome and hypercholesterolemia mouse models suggest that the DSCR-1 gene protects against abnormal cornea vascularization and associated blindness by suppressing oxidized LDL cholesterol production and downstream angiogenic signaling during chronic high cholesterol. While the neurological pathology of Down syndrome patients worsens with age, they are less susceptible to age-related vascula

Antidepressiv medicin skulle kunna funka mot barncancer
I en ny studie visar forskare att en vanlig antidepressiv medicin kan bromsa tillväxten av barnsarkom, åtminstone i möss och i celler som odlats i laboratorium. Resultaten väcker hopp om nya behandlingsstrategier mot denna cancerform. – Även om den här studien gjordes i möss och vi ännu inte vet hur överförbara resultaten är till människor, så ger det oss hopp om att kunna använda vanliga läkemed

Astronomers discover clues that unveil the mystery of fast radio bursts
Fast radio bursts, or FRBs—powerful, millisecond-duration radio waves coming from deep space outside the Milky Way Galaxy—have been among the most mysterious astronomical phenomena ever observed. Since FRBs were first discovered in 2007, astronomers from around the world have used radio telescopes to trace the bursts and look for clues on where they come from and how they're produced.

Honey bees lose sleep after ingesting pesticides, leading to greater stress and lower hive survival rates
Bees that ingest nonlethal levels of popular pesticides resembling nicotine, known as neonicotinoids, are losing sleep, according to new research from Vanderbilt University. That disruption of their circadian rhythm causes honey bees to lose their sense of time and navigation, leading to broader stress within highly social bee populations and lower hive survival rates.
