Proteogenomics enhances the identification of therapeutic vulnerabilities in breast cancer
- EurekAlert
- 20/11/18 06:00
Applying powerful proteogenomics approaches to breast cancer, researchers propose more precise diagnostics, identify new tumor susceptibilities for translation into treatments and implicate new mechanisms involved in breast cancer treatment resistance.
Research on environmental history: 330-year-old poplar tree tells of its life
- EurekAlert
- 20/11/18 06:00
Similar to genetic mutations, epigenetic changes, i.e. gene modifications that do not occur on the primary DNA sequence, sometimes arise accidentally in plants and can be transmitted across generations. Using trees as a model, researchers have now shown for the first time that these so-called epimutations accumulate continuously throughout plant development, and that they can be employed as a...
Researchers recognize a viral protein's M.O. by just 3% of its size
- EurekAlert
- 20/11/18 06:00
Skoltech researchers and their colleagues from Russia, the US, and Sweden have described an unusual RNA polymerase that helps a poorly studied crAss-like bacteriophage transcribe its genes. They "caught" this enzyme by a tiny -- less than 3% of its size -- portion of the amino acid sequence that was similar to other RNA polymerases.
Review examines sexual aggression in mammals
- EurekAlert
- 20/11/18 06:00
A recent review of published studies in non-human mammals examines 'sexual disturbance,' or male behavior towards a female around mating that can be costly for the female -- for example, that might inflict physical harm or cause mother-offspring separation. The findings are published in Mammal Review.
Revolutionary CRISPR-based genome editing system treatment destroys cancer cells
- EurekAlert
- 20/11/18 06:00
Researchers at Tel Aviv University (TAU) have demonstrated that the CRISPR/Cas9 system is very effective in treating metastatic cancers, a significant step on the way to finding a cure for cancer. The researchers developed a novel lipid nanoparticle-based delivery system that specifically targets cancer cells and destroys them by genetic manipulation. The system, called CRISPR-LNPs, carries a...
Saving your data together helps birds and bird research
- EurekAlert
- 20/11/18 06:00
It hasn't been more than a year and a half since the international researchers' network SPI-Birds started officially. Together they collect, secure and use long-term breeding population data of 1.5 million individually recognisable birds... and counting. Big questions in ecology and evolution can be answered using this data. Today, the publication of SPI-Birds' first scientific paper in the...
Scientists develop a magnetic switch with lower energy consumption
- EurekAlert
- 20/11/18 06:00
Joint research conducted by the UAB has shown the ability to switch magnetizacion « on » and « off » using voltage in a new class of easy-to-fabricate materials containing nitrogen. These results, published in Nature Communications, may be used to reduce energy consumption in electronic technologies.
Single-cell technique could provide 'egg health' indicators
- EurekAlert
- 20/11/18 06:00
Using the power of single-cell analysis, researchers at the Babraham Institute have assessed the effects of age on egg cells (oocytes) in mice, particularly looking to identify genomic and epigenetic factors that relate to reduced developmental competence. The knowledge uncovered by this research provides new insights into the mechanisms underlying egg quality and is relevant to the development of...
Small finlets on owl feathers point the way to less aircraft noise
- EurekAlert
- 20/11/18 06:00
Collaboration between City, University of London and RWTH Aachen University researchers reveals how these micro-structures enable silent flight.
Solving a mystery: How the TB bacterium develops rapid resistance to antibiotics
- EurekAlert
- 20/11/18 06:00
These slow growing bacteria have long puzzled TB researchers with their fairly rapid resistance to antibiotics. Researchers may have been barking up the wrong tree in exploring genetics, because the answer seems to lie in the epigenetic domain.
Starved, stuffed and squandered: Consequences of decades of global nutrition transition
- EurekAlert
- 20/11/18 06:00
Just a handful of rice and beans - a part of our world is starved. Hawaiian Pizza and ice-cream - another part of our world is stuffed, throwing away food every day. This gap is likely to worsen, while food waste will increase and pressure on the environment will go up, a new study shows.
Study confirms contribution of bioenergy to climate change mitigation
- EurekAlert
- 20/11/18 06:00
Across-border team of researchers refute arguments that carbon debt, opportunity cost and indirect land-use change prevent greenhouse gas mitigation by biofuels.
Study finds health trade-offs for wildlife as urbanization expands
- EurekAlert
- 20/11/18 06:00
City living appears to improve reproductive success for migratory tree swallows compared to breeding in more environmentally protected areas, a new five-year study suggests. But urban life comes with a big trade-off - health hazards linked to poorer water quality.
Study finds sexual lineage plays key role in transgenerational plasticity
- EurekAlert
- 20/11/18 06:00
A new pair of papers published in the Journal of Animal Ecology has shown that sexual lineage matters for how offspring receive adaptations from parents in stickleback fish. Researchers in the Bell lab studied how parents who were exposed to predators passed the behavioral information to their offspring in different ways based on sex.
Study identifies reasons for soaring nuclear plant cost overruns in the US
- EurekAlert
- 20/11/18 06:00
MIT researchers have analyzed the causes of many cost overruns on new nuclear power plants in the US, which have soared in the past 50 years. The findings may help designers of new plants build in resilience to prevent such added costs.
Suicidal risk during pregnancy, after childbirth on the rise
- EurekAlert
- 20/11/18 06:00
The prevalence of suicidal thoughts and self-harm in the year before and after giving birth nearly tripled among childbearing people between 2006 and 2017, according to a new study.
Super-resolution "street view" microscopy hits the SPOT
- EurekAlert
- 20/11/18 06:00
An advanced technique called SPOT is giving researchers a opportunities to study the sophisticated world of lipid dynamics within cells.
Surgeons' expectations more accurate in predicting outcomes after lumbar spine surgery
- EurekAlert
- 20/11/18 06:00
Surgeons' preoperative expectations were more accurate than patients' expectations in predicting patient-reported outcomes two years after lumbar spine surgery, according to a longitudinal study by investigators at Hospital for Special Surgery (HSS).
Surprises in 'active' aging
- EurekAlert
- 20/11/18 06:00
Aging is a process that affects not only living beings. Many materials, like plastics and glasses, also age -- ie they change slowly as their particles try to pack better. Biological materials, such as living tissue, show similar behaviour to glasses except that the particles are actual cells with their own propulsion. Researchers at Göttingen University used computer simulations to explore the...
System can sterilize medical tools using solar heat
- EurekAlert
- 20/11/18 06:00
Autoclaves, which are used to sterilize medical tools, require a steady supply of hot, pressurized steam. Researchers at MIT and the Indian Institute of Technology have come up with a way to generate that steam passively, using just the power of sunlight, to help maintain safe, sterile equipment at low cost in remote locations.

Tau protein changes in Alzheimer's disease correlate with dementia stage
- EurekAlert
- 20/11/18 06:00
In new research, Judith Steen, Ph.D. and colleagues at Boston Children's Hospital show for the first time that a pathological form of the tau protein involved in the progression of Alzheimer's disease changes over time due to chemical modifications. Observed in brain tissue from Alzheimer's patients, the modified tau forms correlated with stages of dementia. These discoveries likely mean it will...
The bull Y chromosome has evolved to bully its way into gametes
- EurekAlert
- 20/11/18 06:00
In a new study, published Nov. 18 in the journal Genome Research, scientists in the lab of Whitehead Institute Member David Page present the first ever full, high-resolution sequence of the Y chromosome of a Hereford bull. The research, more than a decade in the making, suggests that bulls' Y chromosomes have evolved dozens of copies of the same genes in a selfish attempt to make more males -- a...
