University of Liverpool scientists make promising discovery in fight against breast cancer

Researchers from the University of Liverpool have created a biomedical compound that has the potential to stop the spread of breast cancer. A recently published paper details these early findings. Scientists from the Chemistry and Biochemistry Departments at the University of Liverpool and Nanjing Medical School in China have discovered a possible way to block proteins produced in the body when a patient has cancer and which causes its spread to other parts of the body. This process, called metastasis, is largely responsible for patient deaths. The major problem hindering the successful treatment of commonly occurring cancers is not the primary tumour which can usually be removed by ...

Male crickets court females in unison – unless rivals get too close

Male crickets sing in unison to attract females – but stop singing if a rival gets too close, new research shows. University of Exeter scientists watched more than 100 male field crickets, and measured how often they chirped at the same time (called “singing overlap”). Singing by males one to five metres away from a listening male had a “stimulatory effect”, leading to a chorus of crickets singing together. However, males were less likely to sing if another cricket chirped within one metre – possibly because the territorial insects instead chose to fight ...

Some people’s brain function still affected by Long COVID years after infection

Some people’s brain function still affected by Long COVID years after infection  UK researchers have found that people with longer-term COVID-19 symptoms including brain fog showed reduced performance in tasks testing different mental processes up to two years after infection with the virus.   Researchers from King’s College London looked at whether infection with COVID-19 affected performance in two rounds of online cognitive testing that took place in 2021 and 2022. Data was collected for over 3,000 participants of the COVID Symptom Study Biobank study, across 12 tasks that tested memory, attention, reasoning, processing speed and ...

Researchers decipher the secrets of Benjamin Franklin’s paper money

Benjamin Franklin may be best known as the creator of bifocals and the lightning rod, but a group of University of Notre Dame researchers suggest he should also be known for his innovative ways of making (literal) money. During his career, Franklin printed nearly 2,500,000 money notes for the American Colonies using what the researchers have identified as highly original techniques, as reported in a study published this week in the Proceedings of the National Academy of Sciences. The research team, led by Khachatur Manukyan, an associate research professor ...

On the hunt for strangeness

NEWPORT NEWS, VA – Peter Hurck has been searching for strange particles, named such because they contain strange quarks, since beginning work on his Ph.D. As the 2023 Jefferson Science Associates (JSA) Postdoctoral Prize winner, he’ll continue conducting data analyses to identify strange particles and learn about their properties. Many of these experiments that contribute to the data Hurck is analyzing are conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, which is managed and operated by JSA. “Strangeness hasn't been studied as much because it's quite ...

To stick or to bounce: Size determines the stickiness of cosmic dust aggregates

Microparticle dust aggregates, which are thought to play a role in the formation of new planets, are less likely to stick together after a collision when the aggregates are larger. Current evidence suggests that microparticles of cosmic dust collide and stick together to form larger dust aggregates that may eventually combine and develop into planets. Numerical models that accurately characterize the conditions required for colliding microparticle aggregates to stick together, rather than bounce apart, are therefore ...

Long-term changes in waves and storm surges have not impacted global coastlines

Changes in ocean wave and storm conditions have not caused long-term impacts on sandy coastlines in the past 30 years, a new study has found. Published today in Scientific Reports, the study draws on data from 30 years of global satellite and model studies to investigate whether changes in ocean wave conditions will have an impact on the stability of coastal environments. The compounding effect of climate change driven variations in waves, storm surge and sea level rise is projected to lead to shoreline position change along most of the world’s sandy coasts.

Subseasonal transition of sea-ice anomalies in the Barents–Kara Sea in winter modulated by the “warm Arctic–cold Eurasia” pattern

The “warm Arctic–cold Eurasia” is one of the most significant patterns of winter climate system changes in the mid-high latitudes of the Northern Hemisphere. In winter 2020/21, this large-scale pattern underwent a significant and intense subseasonal reversal between the early and late winter. At the same time, the sea-ice anomalies in the Barents–Kara Sea changed from being significantly negative in early winter to positive in late winter. For the slow-varying process of winter sea ice, the rapid freezing ...

Miocene period fossil forest of Wataria found in Japan

An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch. Complete plant fossils are seldom found as a single piece, as wood, leaves, flowers, fruits, seeds, or pollen detach easily from plants. This results in leaves and trunks having separate scientific names. Putting together the different parts to reveal the complete plant is like putting together a jigsaw puzzle. Connecting these dots and reconstructing plants is important to establish their taxonomic identity—their ...

Going the distance for better wireless charging

A better way to wirelessly charge over long distances has been developed at Aalto University. Engineers have optimized the way antennas transmitting and receiving power interact with each other, making use of the phenomenon of “radiation suppression”. The result is a better theoretical understanding of wireless power transfer compared to the conventional inductive approach, a significant advancement in the field. Charging over short distances, such as through induction pads, uses magnetic near fields to transfer power with high efficiency, but at longer distances the efficiency dramatically drops. New research shows that this high efficiency ...

Probiotic combo stops bacteria that cause toxic shock syndrome

Highlights: Toxic shock syndrome (TSS) is a rapid-onset, life-threatening disease associated with strains of Staphylococcus aureus. New findings published in Microbiology Spectrum suggest that a probiotic combination could reduce incidence of TSS. In lab experiments, the probiotics reduced production of the superantigen that causes TSS. The researchers say a probiotic approach may also help people who suffer from other staph infections, including those with atopic dermatitis or type 2 diabetes. Washington, D.C. – The widespread, pathogenic microbe Staphylococcus aureus can colonize the skin and mucous membranes throughout the body, particularly the vagina ...

Tourists help scientists reveal microplastic pollution on remote Arctic beaches

Tourists acting as citizen scientists have helped a research team detect microplastics on remote Arctic beaches. The global scale of plastic production means that these tiny fragments of plastic are now ubiquitous, and scientists fear that ocean currents will cause plastic to accumulate in the Arctic, damaging ecosystems. But our knowledge of the scale and type of plastic pollution in the Arctic is incomplete. Researchers recruited holidaymakers to carry out sample collection during cruises, hoping to fill in some of the gaps in their knowledge. “Plastic pollution is now ubiquitous.

A ‘toolbox of biocatalysts’ improves control over free radicals

(Santa Barbara, Calif.) — One of the central challenges for synthetic chemists is to impose control over free radicals. Highly reactive molecules with an unpaired electron, free radicals may be familiar to you; these are the type of molecules we take antioxidant supplements for, in an effort to tame oxidative stress. In the world of synthetic chemistry, however, free radicals hold a lot of promise. “Free radical chemistry is very useful for the synthesis of both bioactive small molecules and everyday polymers,” said UC Santa Barbara chemistry professor Yang Yang, an author of a paper on the matter that appears in Nature Catalysis. “However, ...
