Spectacular discoveries during excavation of unique flagship Gribshunden
For three weeks the royal warship Gribshunden (1495) has been excavated on the seabed of the Baltic Sea off the coast of southern Sweden. Among others things, a very early firearm—one of the earliest to be found on a ship anywhere in the world—as well as a beautifully formed drinking tankard, with a crown-like engraving, have been found.
Study shows how serotonin and a popular anti-depressant affect the gut's microbiota

- 19/9/6 15:28
Researchers have developed an approach for precisely measuring changes in the magnetic order of antiferromagnetic materials in real time. Further understanding of these materials could enable electronic devices with speeds orders of magnitude higher.
How our brain filters sounds
- ScienceDaily
- 19/9/6 15:27
When two identical sounds are repeated quickly, a filter reduces the attention that the brain directs to the second sound it hears. In people with schizophrenia, this ability to reduce the brain's response to identical sounds does not function properly. But the question is: Why? Neuroscientists have been investigating the mechanism that lies behind this auditory sensory gating. Their results show...

- ScienceDaily
- 19/9/6 15:27
Researchers have developed a new platinum-based catalytic system that is far more durable than traditional commercial systems and has a potentially longer lifespan. The new system could, over the long term, reduce the cost of producing fuel cells.
'Tiny fat bubbles' can boost immunity, calm disease

People living with inflammatory autoimmune disease could benefit from an 'immune system reboot', and researchers have isolated specific cells to target.
Bad to the bone or just bad behavior?
- ScienceDaily
- 19/9/6 15:27
A new study suggests that the way we perceive others' bad behavior -- as either biological and innate or potentially changeable -- impacts our willingness to cut them some slack.
Fe metabolic engineering method succeeds in producing 1,2,4-butanetriol sustainably from biomass
- ScienceDaily
- 19/9/6 15:27
A more environmentally-friendly and sustainable method of producing the useful chemical 1,2,4-butanetriol has been discovered. The team utilized a method involving the direct fermentation of xylose in rice straw using an engineered yeast strain to produce 1,2,4-butanetriol.
How to build a 'perfect' language
It's well known that JRR Tolkien wrote the Lord of the Rings cycle to create people to speak the languages he had invented. But, in the television age, artificially created or invented languages—we call them "conlangs"—have been gaining increasing attention with the popularity of television series such as Star Trek and Game of Thrones, and films such as Avatar.
Are you mentally well enough for college?
Last spring an 18-year-old college freshman who got straight A's in high school—but was now failing several courses—came to my office on the campus where I work as a psychologist.
New insight into how much atmosphere Mars lost
A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements of this tracer—isotopes of oxygen—have disagreed significantly. An accurate measurement of this tracer is important to estimate how much atmosphere Mars once had before...
Scientists couple magnetization to superconductivity for quantum discoveries
Quantum computing promises to revolutionize the ways in which scientists can process and manipulate information. The physical and material underpinnings for quantum technologies are still being explored, and researchers continue to look for new ways in which information can be manipulated and exchanged at the quantum level.

Oceanographers found that marine microbes process sulfonate, a plentiful marine nutrient, in a way that is similar to soils.
Researchers find alarming risk for people coming off chronic opioid prescriptions
- ScienceDaily
- 19/9/6 15:06
A recent study found an alarming outcome: Patients coming off opioids for pain were three times more likely to die of an overdose in the years that followed.
GIS and eDNA analysis system successfully used to discover new habitats of rare salamander
- ScienceDaily
- 19/9/6 15:06
A research team has successfully identified an unknown population of the endangered Yamato salamander (Hynobius vandenburghi) in Gifu Prefecture, using a methodology combining GIS and eDNA analysis. This method could be applied to other critically endangered species, in addition to being utilized to locate small organisms that are difficult to find using conventional methods.
More targeted, less toxic: The golden future of cancer treatment
- ScienceDaily
- 19/9/6 15:06
New synthetic molecules are up to 24 times more effective at killing cancer cells than a widely-used cancer drug and they're built with resistance-fighting features to keep them effective over time, unlike current chemotherapies. Pre-clinical studies show the molecules are promising candidates for development into a new class of gold-based drugs that can wipe out the cancer without destroying...
Sugar alters compounds that impact brain health in fruit flies
- ScienceDaily
- 19/9/6 15:05
When fruit flies are exposed to a high sugar diet, key metabolites associated with brain health become depleted, according to a new study.
Typhoid toxin accelerates cell aging to enhance killer infection

Scientists have revealed how the typhoid toxin works to hijack DNA repair machines and accelerate the aging of cells, a breakthrough that could pave the way for new strategies to combat the killer disease.
Role of cancer protein ARID1A at intersection of genome stability and tumor suppression
- ScienceDaily
- 19/9/6 15:05
The ARID1A tumor suppressor protein is required to maintain telomere cohesion and correct chromosome segregation after DNA replication. This finding indicates that ARID1A-mutated cells undergo gross genomic alterations that are not compatible with survival and explains the lack of genomic instability characteristic of ARID1A-mutated cancers.
New Zealand launches plan to revive the health of lakes and rivers
New Zealand's government released a plan to reverse the decline of iconic lakes and rivers this week. It proposes higher standards for water quality, interim controls on land intensification and a higher bar on ecosystem health.
