Researchers solve a long-standing problem in organic chemistry
- ScienceDaily
- 20/7/16 22:30
Chemists have for a long time been interested in efficiently constructing polyenes - not least in order to be able to use them for future biomedical applications. However, such designs are currently neither simple nor inexpensive. Scientists have now found a bio-inspired solution to the problem.

Researchers have discovered new information about how a dangerous parasite takes control of a patient's cells as it spreads throughout their body, an important finding that could help in the development of new drugs to treat this infection.
Scientists identify new species of sea sponge off the coast of British Columbia, Canada
- ScienceDaily
- 20/7/16 22:30
A research team has published a study on the discovery of a new sponge that is abundant in the region, making up nearly 20 per cent of the live sponges in the reefs off the coast of British Columbia. The new species -- called Desmacella hyalina -- was discovered using an underwater robot that traveled along the ocean floor, surveying reefs and collecting samples.

A new study finds that groups led by subordinate males outperform those led by dominant and aggressive males.
About 94 per cent of wild bee and native plant species networks lost
- ScienceDaily
- 20/7/16 20:47
Climate change and an increase in disturbed bee habitats from expanding agriculture and development in northeastern North America over the last 30 years are likely responsible for a 94 per cent loss of plant-pollinator networks, researchers found. The researchers looked at plant-pollinator networks from 125 years ago through present day.
Strategies for recycling of solar panels
- ScienceDaily
- 20/7/16 20:47
Researchers have conducted the first global assessment into the most promising approaches to end-of-life management for solar photovoltaic (PV) modules.
Membrane technology could cut emissions and energy use in oil refining
- ScienceDaily
- 20/7/16 20:47
New membrane technology developed by a team of researchers could help reduce carbon emissions and energy intensity associated with refining crude oil. Laboratory testing suggests that this polymer membrane technology could replace some conventional heat-based distillation processes in the future.
Two paths of aging: New insights on promoting healthspan
- ScienceDaily
- 20/7/16 20:47
Scientists have unraveled key mechanisms behind the mysteries of aging. They isolated two distinct paths that cells travel during aging and engineered a new way to genetically program these processes to extend lifespan. Cells embark upon either a nucleolar or mitochondrial path early in life, and follow this ''aging route'' throughout their entire lifespan through decline and death. At the heart...
Genetics could help protect coral reefs from global warming
- ScienceDaily
- 20/7/16 20:47
The research provides more evidence that genetic-sequencing can reveal evolutionary differences in reef-building corals that one day could help scientists identify which strains could adapt to warmer seas.
Megaphages harbor mini-Cas proteins ideal for gene editing
- ScienceDaily
- 20/7/16 20:47
Cas proteins like CRISPR-Cas9 have great potential for gene therapy to treat human disease and for altering crop genes, but the gene-targeting and gene-cutting Cas proteins are often large and hard to ferry into cells with viral vectors such as adenovirus. Scientists have now discovered a hypercompact Cas protein, Cas-phi, that should work better. It is half the size of Cas9 and apparently evolved...
Will telehealth services become the norm following COVID-19 pandemic?
- ScienceDaily
- 20/7/16 20:47
Experts address whether the routine use of telehealth for patients with cancer could have long-lasting and unforeseen effects on the provision and quality of care.
Evidence for decades-old theory to explain the odd behaviors of water
- ScienceDaily
- 20/7/16 20:47
A new study provides strong evidence for a controversial theory that at very cold temperatures water can exist in two distinct liquid forms, one being less dense and more structured than the other. Researchers conducted computer simulations of water molecules to discover the critical point at the transition between the two forms.
Chest x-rays show more severe COVID-19 in non-white patients
- ScienceDaily
- 20/7/16 20:47
Racial/ethnic minority patients admitted to the hospital with COVID-19 infection are more likely to have more severe disease on chest X-rays than white/non-Hispanic patients, increasing the likelihood of adverse outcomes, such as intubation or death, according to a new study.
Dangerous blood clots form in leg arteries of COVID-19 patients
- ScienceDaily
- 20/7/16 20:47
COVID-19 is associated with life-threatening blood clots in the arteries of the legs, according to a new study. Researchers said COVID-19 patients with symptoms of inadequate blood supply to the lower extremities tend to have larger clots and a significantly higher rate of amputation and death than uninfected people with the same condition.
New test offers clarity for couples struggling to conceive
- ScienceDaily

A male fertility test could help predict which men might need treatment and which couples might have success with different forms of assisted reproduction.
How nutrient-starved cells recycle internal components
- ScienceDaily
- 20/7/16 18:30
Researchers systematically surveyed the entire protein landscape of normal and nutrient-deprived cells to identify which proteins and organelles are degraded by autophagy.
Gel that breaks down, puts itself back together could improve delivery of oral drugs
- ScienceDaily
- 20/7/16 18:30
An emerging hydrogel material with the capacity to degrade and spontaneously reform in the gastrointestinal tract could help researchers develop more effective methods for oral drug delivery. In research published in Soft Matter, Lehigh University rheologists mimic pH environment of GI tract to shed light on pharmaceutical potential of covalent adaptable hydrogels (CAHs).
Genome guardians stop and reel in DNA to correct replication errors
- ScienceDaily
- 20/7/16 18:30
New research shows how proofreading proteins prevent DNA replication errors by creating an immobile structure that calls more proteins to the site to repair the error. This structure could also prevent the mismatched region from being ''packed'' back into the cell during division.

- 20/7/16 18:30
No year since weather records began was as hot and dry as 2018. A first comprehensive analysis of the consequences of this drought and heat event shows that central European forests sustained long-term damage. Even tree species considered drought-resistant, such as beech, pine and silver fir, suffered.
