When a chromosome is lost: How do human cells react to monosomy?
Tiny lasers acting together as one: Topological vertical cavity laser arrays
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were unknown. This is where researchers at the Technical University of Kaiserslautern (TUK) came in. In collaboration with the European Molecular Biology...
Ultrathin electronic barrier layer to control interface luminescence
Israeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser—a highly effective laser network the size of a grain of sand. The findings are presented in a new joint research paper published online by the prestigious journal Science on Friday, September 24.

Oldest human footprints in North America found in U.S. park
Dendrochronologists, Paolo Cherubini with the Swiss Federal Institute for Forest, Snow and Landscape Research, has published a Perspective piece in the journal Science outlining the use of dendrochronology to determine the approximate age of old wooden stringed instruments. In his paper, Cherubini notes that analysis of tree rings of some instruments can be used to determine the terminus post...

Video: How lemur research can help endangered species
Experiment aims to address a gender gap where most space medicine research has been carried out on menIt may sound like a prolonged spa break but when 20 women tuck themselves into a waterbed in the south of France for five days this week, it will be under the guise of a scientific study into the impact of space flight on the female body.The experiment, by the European Space Agency, will simulate...
How COVID-19 upended our understanding of migration, citizenship and inequality
Research scientists Marina Blanco, Ph.D. and Lydia Greene, Ph.D. study lemurs at the Duke Lemur Center in Durham, North Carolina (home to the largest population of lemurs outside of Madagascar). Some people might assume that they do this just to hang out with these adorable primates all day, but the truth is that this research could be critical to the survival of some of the world's most...
Geological cold case may reveal critical minerals
The COVID-19 pandemic has shown that the global system governing migration may not be sustainable. Temporary migration schemes including those for seasonal agriculture workers or those allowing for construction and care work no longer function when people's mobility is hampered because of a rapidly circulating and dangerous virus.
Fossil footprints prove humans populated the Americas thousands of years earlier than we thought
Researchers on the hunt for why cold eclogites mysteriously disappeared from geological records during the early stages of the Earth's development may have found the answer, and with it clues that could help locate critical minerals today.
Bizarre armoured spikes belong to oldest ankylosaur ever discovered
Our species began migrating out of Africa around 100,000 years ago. Aside from Antarctica, the Americas were the last continents humans reached, with the early pioneers crossing the now-submerged Bering land bridge that once connected eastern Siberia to North America.
Lab grown tumor models could improve treatment for pancreatic cancer
An unusual fossil showing a series of spikes fused to a rib has been revealed to be the remains of the oldest ankylosaur ever found and the first from the African continent.

New research reveals credit rating agencies responded too slowly to COVID-19
An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.
Can sustainability standards effectively mitigate food system challenges?
The first study into the effect of COVID-19 on sovereign credit ratings found that rating agencies were slow to react to the pandemic's unprecedented economic and fiscal reverberations. The research raises questions about the timeliness and reliability of prominent creditworthiness measures, with potentially significant consequences for investors and for public debt and global financial stability.
Earth and Venus grew up as rambunctious planets
While agrifood production is essential for feeding our growing global population, it can also contribute to environmental and social problems, including deforestation, biodiversity loss, poor or precarious labor conditions, and persistent poverty. Certification and standards can encourage use of sustainable production practices, but how effective are such programs in addressing food system...
Sponges, blood cells and sound-art: the exhibition hoping to cure my cancer
What doesn't stick comes around: Using machine learning and simulations of giant impacts, researchers at the Lunar and Planetary Laboratory found that the planets residing in the inner solar systems were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation.
‘We haven’t finished the job’: JVT reflects on 18 months of Covid
The UK’s first ever cancer research exhibition pairs up patients with researchers to show the creative paths taken on the cutting edge of human discoveryShortly before the pandemic hit, I found myself dressed in a red lab coat, trying to find a cure for blood cancer. Although that might be overstating things a little. It’s Professor Dominique Bonnet who is at the cutting edge of cancer...
The US is about to kick-start its controversial covid booster campaign
Exclusive: Listen to the experts, says deputy chief medical officer Jonathan Van-Tam, not the celebritiesThey didn’t ask for the spotlight, and sometimes they didn’t always seem comfortable under the media glare.But the scientists who came into our lives at the start of the coronavirus pandemic became household names. None more so than Prof Jonathan Van-Tam. Continue...
Machine learning uncovers 'genes of importance' in agriculture and medicine
The news: The White House is set to kick off its booster shot campaign today, after Centers for Disease Control and Prevention director Rochelle Walensky overruled her own agency’s advisors in favor of recommending third doses of the Pfizer-BioNTech vaccine for frontline workers.
Who gets it: There are three groups of Americans now eligible for a booster shot: those 65 and older, some adults...
A Hunter-Gatherer’s Guide to the 21st Century review – sciencey self-help
Machine learning can pinpoint "genes of importance" that help crops to grow with less fertilizer, according to a new study published in Nature Communications. It can also predict additional traits in plants and disease outcomes in animals, illustrating its applications beyond agriculture.
How old is that lobster in the sea? It's now easier to find the answer
Evolutionary biologists Heather Heying and Bret Weinstein show how human nature is at odds with modern society, in a study soaked in pseudoscienceImagine discovering a fence in the middle of a desert. Not immediately seeing its purpose, you might think: “Let’s get rid of this useless fence!” But are you sure about that? Maybe you’re at the edge of a field of angry wildebeest, and by...
