Nanospears deliver genetic material to cells with pinpoint accuracy

Mar 14 2018 - 00:03
In a step toward accelerating the production of new gene therapies, scientists report in ACS Nano that they have developed remote-controlled, needle-like nanospears capable of piercing membrane walls and delivering DNA into selected cells. They say the new technique, which can ferry biological materials to cells with pinpoint accuracy, overcomes many of the existing barriers to effective gene modification.

Removing heavy metals from water with MOFs

Mar 14 2018 - 00:03
An estimated 1 billion people do not have access to clean drinking water, a problem expected to worsen with climate change, according to the World Health Organization. In addition, higher energy needs and increased use of heavy metals in industrial processes have increased human exposure to these toxic materials from drinking water in recent decades. Researchers now report in ACS Central Science a new material that can remove heavy metals and provide clean drinking water in seconds.

Elevated lead in private wells could pose health risks

Mar 14 2018 - 00:03
Since the Flint Water Crisis in Michigan, concern in the US over lead in drinking water has increased. Information about water from private wells has been limited because such wells are exempt from the 1974 Safe Drinking Water Act, the 1986 Lead Ban and the 2011 Reduction of Lead in Drinking Water Act. Now, researchers report a case study in ACS' journal Environmental Science & Technology that sheds some light on the hidden health risks.

For nanomedicine, cell sex matters

Mar 14 2018 - 00:03
A research team has demonstrated that cell sex considerably influenced cellular uptake of nanoparticles and found that cells from men and women responded differently to reprogramming techniques used to enhance the ability of the cells to differentiate into a greater variety of cell types.

Chain reaction of fast-draining lakes poses new risk for Greenland ice sheet

Mar 14 2018 - 00:03
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.

Artificial and biological cells work together as mini chemical factories

Mar 14 2018 - 00:03
Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications.

'Body on a chip' could improve drug evaluation

Mar 14 2018 - 00:03
MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before they are approved for human use. Using a microfluidic chip that connects tissue samples from up to 10 organs, the researchers can accurately replicate human organ interactions, allowing them to measure the effects of drugs on different parts of the body.

High numbers of elderly Japanese women will soon live in poverty, predicts new model

Mar 14 2018 - 00:03
Roughly one in four elderly Japanese women will live below the poverty level in the near future, predicts a model of the Japanese pension system. Never-married and divorced women will be the most affected, with around 50 percent of these women predicted to become impoverished in the next 50 years.

Are palaeontologists naming too many species?

Mar 14 2018 - 00:03
A comprehensive new study looking at variations in Ichthyosaurus, a common British Jurassic ichthyosaur (sea-going reptile) also known as 'Sea Dragons', has provided important information into recognizing new fossil species.

New research solves the 60-year-old paleontological mystery of a 'phantom' dicynodont

Mar 14 2018 - 00:03
A new study has re-discovered fossil collections from a 19th century hermit that validate 'phantom' fossil footprints collected in the 1950s showing dicynodonts coexisting with dinosaurs.

Smoke-damaged airway tissue restored on switching to glo

Mar 14 2018 - 00:03
Studies by British American Tobacco show that airway tissue damaged on exposure to smoke was restored when exposed to vapor from glo rather than smoke. These results add to evidence that glo has reduced risk potential compared to cigarettes. glo is a tobacco heating product designed to heat rather than burn tobacco. Tests show that glo heated tobacco vapor has around 90-95 percent less of certain toxicants than cigarette smoke.

Decreased oxygen levels could present hidden threat to marine species

Mar 14 2018 - 00:03
In research published in Nature Scientific Reports, scientists from the University of Plymouth have shown that creatures which develop in hypoxic (low oxygen) conditions in the marine environment could experience previously unseen hindered development, and become compromised as adults.

Exploration of a new chemical synthesis process -- synergy of two catalysts in one flask

Mar 14 2018 - 00:03
Development of a general and simple reaction by an organocatalyst and a transition-metal catalyst in cooperation is highly desirable for various organic syntheses but remains a challenge. Herein, we report the one-step synthesis of a ketone from an aldehyde by the combination of thiazolium N-heterocyclic carbene and palladium/bisphosphine catalysts in one flask. The two catalysts function in a synergistic manner. This study is expected to lead to new synthesis processes of precursor compounds for medications.

It's not only size, but scales that matter in some male moth antennae

Mar 13 2018 - 00:03
Male moths have evolved intricate scale arrangements on their antennae to enhance detection of female sex pheromones, which allows them to keep their antennae small enough to maximize flying, new research suggests.

Climate change risk for half of plant and animal species in biodiversity hotspots

Mar 13 2018 - 00:03
Up to half of plant and animal species in the world's most naturally rich areas, such as the Amazon and the Galapagos, could face local extinction by the turn of the century due to climate change if carbon emissions continue to rise unchecked. Even if the Paris Climate Agreement 2°C target is met, these places could lose 25 percent of their species. Researchers examined the impact of climate change on nearly 80,000 plant and animal species in 35 areas.
