Migrating starlings are no copycats
2024-07-05
Young, naïve starlings are looking for their wintering grounds independently of experienced conspecifics. Starlings are highly social birds throughout the year, but this does not mean that they copy the migration route from each other. By revisiting a classic ‘displacement’ experiment and by adding new data, a team of researchers at the Netherlands Institute of Ecology (NIOO-KNAW) and the Swiss Ornithological Institute (Vogelwarte Sempach) have settled a long-lasting debate. Their findings are now published in the scientific journal Biology Letters.
The question of how migratory birds locate their migration ...
Osteoblast-derived extracellular vesicles exert bone formation effects by WIF1-mediated regulation of mitophagy
2024-07-05
Osteoporosis is a common disorder, especially in the elderly, characterized by bone loss and increased fracture risk. Treatments target abnormal osteoclast activity but face adherence issues. The disease disrupts the balance between bone resorption and formation. Key factors like Wnt signaling and mitochondrial health influence osteoblast differentiation. However, WIF1's role in regulating mitophagy and osteoblast differentiation remains unclear.
This research investigated the role of WIF1 in controlling the osteogenic differentiation stage of the OB precursor cell line (MC3T3-E1 cells) and assessed ...
Based on the improvement of detection technology, a new summary is proposed for the application of liquid biopsy, future clinical trial design and patient management of NSCLC
2024-07-05
This study was led by Kezhong Chen (Department of Thoracic Surgery, Peking University People’s Hospital & Peking University People’s Hospital Thoracic Oncology Institute). In clinical practice, traditional tumor-node-metastasis (TNM) staging had difficulty achieving accuracy in prognosis stratification at the individual patient level. Researchers therefore proposed to introduce blood minimal residual disease (MRD) status and proposed a new tumor-node-metastasis-blood (TNMB) staging system to more accurately and individually define the postoperative status of lung cancer patients (Fig. 1).
LB, well known for its noninvasiveness, easy accessibility, ...

Exploring the radiative effects of precipitation on arctic amplification and energy budget
2024-07-05
One of the key metrics for climate modelling is radiative forcing. Most climate models, including the general circulation models (GCMs), focus on the effects of different atmospheric factors on radiative forcing. However, there are still large uncertainties in satellite observations and multi-model simulations associated with some atmospheric factors. Among them, clouds are a known source of uncertainty in GCMs, leading to radiative biases. However, another possible source of radiative uncertainty is associated with precipitation.
In principle, precipitating particles affect radiative forcing by disrupting incoming shortwave and outgoing longwave radiations. ...

Gondwana’s ultimate hunter – New giant fossil tetrapod found in Namibia
2024-07-05
After three years of meticulous study, an international team of researchers has announced the discovery of a fossilised giant basal tetrapod in Namibia's arid heartland in Nature. A basal tetrapod is an early four-legged vertebrate with fingers and toes, which lived during the transition from water to land. These ancient carnivores are among the earliest ancestors of all modern animals. This nearly complete 3-meter-long skeleton of an adult, unearthed in the Ugab River valley in Damaraland, is the largest ever discovered. This discovery is significant because it challenges previous assumptions that these early four-legged vertebrates, which lived during ...
Offshore windfarms – A threat for electro-sensitive sharks?
2024-07-05
An ongoing research project into the impact of offshore windfarm electromagnetic fields on shark development reveals that the alternating electric currents produced by underwater windfarm cables seems not to disrupt the growth or survival of sharks.
Offshore windfarms are one of the most common marine renewable energy (MRE) producers, and are seen as a pivotal technology in the global transition towards renewable energy and away from fossil fuels that contribute to climate change.
However, their proliferation in marine environments raises new questions about their impacts on wildlife. Energy operators and ...
A 2D device for quantum cooling
2024-07-05
To perform quantum computations, quantum bits (qubits) must be cooled down to temperatures in the millikelvin range (close to -273 Celsius), to slow down atomic motion and minimize noise. However, the electronics used to manage these quantum circuits generate heat, which is difficult to remove at such low temperatures. Most current technologies must therefore separate quantum circuits from their electronic components, causing noise and inefficiencies that hinder the realization of larger quantum systems beyond the lab.
Researchers in EPFL’s Laboratory of ...
MIT engineers find a way to protect microbes from extreme conditions
2024-07-05
Microbes that are used for health, agricultural, or other applications need to be able to withstand extreme conditions, and ideally the manufacturing processes used to make tablets for long-term storage. MIT researchers have now developed a new way to make microbes hardy enough to withstand these extreme conditions.
Their method involves mixing bacteria with food and drug additives from a list of compounds that the FDA classifies as “generally regarded as safe.” The researchers identified formulations that help to stabilize several different types ...
Why the U.S. food system needs agroecology
2024-07-05
Agroecology—a science, practice, and movement which seeks social, political, economic, and environmental sustainability in the global food system—is gaining momentum in the U.S., according to a new Dartmouth-led commentary in Nature Food. As the co-authors report, the approach requires coordination between scientists, farmers, and activists.
"When it comes to sustainable food and agriculture, people in the U.S. tend to be more familiar with organic farming, the production of food without synthetic inputs, and regenerative agriculture, which primarily strives to restore soil health," says lead author Theresa Ong, an assistant professor of environmental studies ...
Fresh wind blows from historical supernova
2024-07-05
A mysterious remnant from a rare type of supernova recorded in 1181 has been explained for the first time. Two white dwarf stars collided, creating a temporary “guest star,” now labeled supernova (SN) 1181, which was recorded in historical documents in Japan and elsewhere in Asia. However, after the star dimmed, its location and structure remained a mystery until a team pinpointed its location in 2021. Now, through computer modeling and observational analysis, researchers have recreated the structure of the remnant white dwarf, a rare occurrence, explaining its ...
Desert-loving fungi and lichens pose deadly threat to 5,000-year-old rock art
2024-07-05
The Negev desert of southern Israel is renowned for its unique rock art. Since at least the third millennium BCE, the hunters, shepherds, and merchants who roamed the Negev have left thousands of carvings (‘petroglyphs’) on the rocks. These figures are mostly cut into ‘desert varnish’: a thin black coating on limestone rock, which forms naturally. Many represent animals such as ibexes, goats, horses, donkeys, and domestic camels, but abstract forms also occur.
Now, a study published in Frontiers in Fungal ...
Scientists map how deadly bacteria evolved to become epidemic
2024-07-04
Pseudomonas aeruginosa – an environmental bacteria that can cause devastating multidrug-resistant infections, particularly in people with underlying lung conditions – evolved rapidly and then spread globally over the last 200 years, probably driven by changes in human behaviour, a new study has found.
P. aeruginosa is responsible for over 500,000 deaths per year around the world, of which over 300,000 are associated with antimicrobial resistance (AMR). People with conditions such as COPD (smoking-related lung damage), cystic fibrosis (CF), and non-CF bronchiectasis, are particularly susceptible.
How P. aeruginosa evolved from an environmental organism into a ...

New brain-to-nerve signaling mechanism reveals potential path to migraine pain
2024-07-04
The rapid influx of cerebral spinal fluid (CSF) and protein solutes released during cortical spreading depression (CSD) in the brain activates neurons to trigger aural migraine headaches, according to a new mouse study. The findings identify a novel non-synaptic signaling mechanism between the brain and peripheral sensory system important for migraine. They also suggest potential pharmacological targets for treating the painful disorder. Migraine with aura, or an aural migraine, is a distinct headache disorder that can include sensory disturbances, such as hearing- or vision-related symptoms that precede onset of ...
Federal grid reforms alone are not enough to solve clean energy interconnection problem
2024-07-04
Although energy production from wind and solar has grown rapidly in the United States, its integration into the national electric grid has been impeded by poor grid interconnection policies, leaving thousands of new facilities for generating renewable energy waiting to be connected to the grid. In a Policy Forum, Les Armstrong and colleagues highlight the interconnection problem and discuss whether federal grid policy reforms alone are enough to address it. Armstrong et al. argue that while the US Federal Energy Regulatory Commission’s (FERC) recent orders to improve this bottleneck are a step in the right direction, fundamental issues remain unaddressed. In the ...
Uncovering “blockbuster T cells” in the gut wins NOSTER & Science Microbiome Prize
2024-07-04
In the gut, dozens of strains of bacteria exert different effects on the immune system that in turn impact our health – fending off pathogens, helping digest food and maybe even influencing behavior. But pinpointing which bacteria exert which effects has been challenging. Better understanding this process could lead to a powerful way to treat a host of diseases. For developing a method by which to zero in on individual gut bacterium’s impacts on T cells, Kazuki Nagashima, a senior research scientist at Stanford University, is the winner of this year’s NOSTER & Science Microbiome ...

2024-07-04
New research describes for the first time how a spreading wave of disruption and the flow of fluid in the brain triggers headaches, detailing the connection between the neurological symptoms associated with aura and the migraine that follows. The study also identifies new proteins that could be responsible for headaches and may serve as foundation for new migraine drugs.
“In this study, we describe the interaction between the central and peripheral nervous system brought about by increased concentrations of proteins released ...
Scientists discover new T cells and genes related to immune disorders
2024-07-04
Researchers led by Yasuhiro Murakawa at the RIKEN Center for Integrative Medical Sciences (IMS) and Kyoto University in Japan and IFOM ETS in Italy have discovered several rare types of helper T cells that are associated with immune disorders such as multiple sclerosis, rheumatoid arthritis, and even asthma. Published July 4 in Science, the discoveries were made possible by a newly developed technology they call ReapTEC, which identified genetic enhancers in rare T cell subtypes that are linked to specific immune ...
The dawn of the Antarctic ice sheets
2024-07-04
In recent years global warming has left its mark on the Antarctic ice sheets. The "eternal" ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international research team led by the Alfred Wegener Institute has now discovered: sediment samples from drill cores combined with complex climate and ice-sheet modelling show that permanent glaciation of Antarctica began around 34 million years ago – ...
Not so selfish after all: Viruses use freeloading genes as weapons
2024-07-04
Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don’t seem to have a role to play in the competition for survival. Or so researchers thought.
These DNA pieces came to be known as “selfish genetic elements” because they exist, as far as scientists could tell, to simply reproduce and propagate themselves, without any benefit to their host organisms. They were seen as genetic hitchhikers that have been inconsequentially passed ...
Researchers identify unknown signalling pathway in the brain responsible for migraine with aura
2024-07-04
A previously unknown mechanism by which proteins from the brain are carried to a particular group of sensory nerves causes migraine attacks, a new study shows. This may pave the way for new treatments for migraine and other types of headaches.
More than 800,000 Danes suffer from migraines – a condition characterised by severe headache in one side of the head. In around a fourth of all migraine patients, headache attacks are preceded by aura – symptoms from the brain such as temporary visual or sensory disturbances preceding the migraine attack by 5-60 minutes.
While ...
Music: Song melodies have become simpler since 1950
2024-07-04
The complexity of the melodies of the most popular songs each year in the USA — according to the Billboard year-end singles charts — has decreased since 1950, a study published in Scientific Reports suggests.
Madeline Hamilton and Marcus Pearce analysed the most prominent melodies (usually the vocal melody) of songs that reached the top five positions of the US Billboard year-end singles music charts each year between 1950 and 2022. They found that the complexity of song rhythms and pitch arrangements decreased over this period as the average number of notes ...
