Did you know multiple sclerosis (MS) means multiple scars? New research shows that the brain and spinal cord scars in people with MS may offer clues to why they developprogressive disability but those with related diseases where the immune system attacks the central nervous system do not. Researchers assessed if inflammation leads to permanent scarring in these three diseases.
DNA duplication linked to the origin and evolution of pine trees and their relatives
- ScienceDaily

A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads.
Making clean hydrogen is hard, but researchers just solved a major hurdle
- ScienceDaily
- 21/7/19 20:34
Researchers have found a low-cost way to solve one half of the water-splitting equation to produce hydrogen as clean energy -- using sunlight to efficiently split off oxygen molecules from water. The finding represents a step forward toward greater adoption of hydrogen as a key part of our energy infrastructure.
RNA modification may protect against liver disease

An RNA modification may offer protection against non-alcoholic fatty liver, a condition that results from a build-up of fat in the liver and can lead to advanced liver disease, according to a new study. The modification may also explain why females tend to have higher fat content in the liver.
Ocean microbes team up brilliantly to gather food when it's scarce
- ScienceDaily
- 21/7/19 20:33
What's a hungry marine microbe to do when the pickings are slim? It must capture nutrients - nitrogen, phosphorus, or iron - to survive, yet in vast expanses of the ocean, nutrients are extremely scarce.
Scientist casts doubt on validity of Boris Johnson’s ‘workplace pilot’
Statistician says PM’s initial excuse for not self-isolating is part of pattern of pilot studies that lack transparencyCoronavirus – latest updatesSee all our coronavirus coverageA scientist has cast doubt on the validity of a workplace pilot scheme used by Boris Johnson and Rishi Sunak to initially avoid self-isolation, accusing the government of secrecy surrounding it and other research.On...
The realization of curved relativistic mirrors to reflect high-power laser pulses
One of the topics investigated in recent physics studies is strong-field quantum electrodynamics (SF-QED). So far, this area has rarely been explored before, mainly because the experimental observation of SF-QED processes would require extremely high light intensities (>1025W/cm2), over three orders of magnitude higher than those attained using the most intense PetaWatt (PW)-class lasers available...
Freeze drying, oral health experiments make speedy return from space station aboard SpaceX Dragon
A suite of International Space Station scientific experiments soon journey back to Earth aboard the 22nd SpaceX commercial resupply services mission for NASA. Scientists on the ground look forward to having their experiments back within hours, an advantage that could provide better results. Dragon undocks from the space station July 7.
Making clean hydrogen is hard, but researchers just solved a major hurdle
For decades, researchers around the world have searched for ways to use solar power to generate the key reaction for producing hydrogen as a clean energy source—splitting water molecules to form hydrogen and oxygen. However, such efforts have mostly failed because doing it well was too costly, and trying to do it at a low cost led to poor performance.
Scientists on the scent of flavor enhancement
Flavor is the name of the game for scientists who want to optimize food for consumption in ways that improve nutrition or combat obesity.
Living near woodlands is good for children and young people's mental health
Analysis of children and young people's proximity to woodlands has shown links with better cognitive development and a lower risk of emotional and behavioral problems, in research led by UCL and Imperial College London scientists that could influence planning decisions in urban areas.
Experts challenge current understanding of transition dairy cow health
For dairy cows, the transition period—the time between a cow giving birth and beginning to produce milk—brings the greatest possibility of health problems. The current widespread belief is that the effects of excess nonesterified fatty acids (NEFA) in the bloodstream and the ensuing hyperketonemia during this period, coupled with low levels of available calcium, are largely responsible for...
Human action key to antibiotic resistance in giant tortoises of Galapagos
The Giant Galapagos tortoises which live in contact with human farming and tourism activities, or in urbanized zones, have more bacterial resistance to antibiotics than those that live in more isolated ecosystems.
Tail without a comet: The dusty remains of Comet ATLAS
A serendipitous flythrough of the tail of a disintegrated comet has offered scientists a unique opportunity to study these remarkable structures, in new research presented today at the National Astronomy Meeting 2021.

A new study shows how biometric data can be used to find potentially challenging and dangerous areas of urban infrastructure. By analyzing eye-tracking data from cyclists navigating Philadelphia's streets, researchers found that these individual-based metrics can provide a more proactive approach for designing safer roadways for bicyclists and pedestrians.
