Carbon nanotubes show promise for high-speed genetic sequencing

Researchers at Arizona State University use single-walled carbon nanotubes to accelerate DNA sequencing, detecting sharp spikes in electrical activity during DNA translocation. The technique has potential to speed up sequencing by thousands of times while reducing costs.

It's never too late to quit smoking and save your vision

A UCLA study published in the American Journal of Ophthalmology found that older women who quit smoking had a significantly lower risk of developing advanced age-related macular degeneration. The research, led by Dr. Anne Coleman, followed 1,958 women over five years and showed that even after age 80, quitting smoking can reduce AMD risk.

Evolution caught in the act

A US-German team studied genetic changes in Arabidopsis thaliana over 30 generations, finding that new mutations occur frequently, with an average of one per genome per generation. The study also reveals that not all parts of the genome are equally affected and provides new estimates for when species split up.

Got a pet tarantula? Then wear eye protection

A 29-year-old man experienced symptoms after a tarantula released 'a mist of hairs' into the air, which got stuck in his eyes. He was treated with topical steroids and made a full recovery. The case highlights the importance of proper eye protection when handling tarantulas.

NASA's TRMM satellite measures Cyclone Laurence's heavy rainfall

Cyclone Laurence dropped heavy rainfall over northwest Australia, with the heaviest totals exceeding 450 mm near Cape Bougainville. The Australian coast also experienced high rainfall totals, with areas along the coast receiving over 150 mm of rain from the cyclone.

Neglected tropical diseases -- momentum must be continued

Lymphatic filariasis, onchocerciasis, and other neglected tropical diseases (NTDs) cause significant morbidity and mortality globally. NTDs have been hindered by limited funding and coordination, but successful control initiatives like onchocerciasis elimination demonstrate the potential for progress.

Using modern sequencing techniques to study ancient modern humans

Researchers overcome DNA contamination hurdle to analyze 30,000-year-old human DNA using modern sequencing techniques, providing insights into the evolution and prehistory of our species. The study allows scientists to directly glimpse into the genetic makeup of ancient humans who lived tens of thousands of years ago.

Catheter ablation prior to defibrillator shock reduces risk of recurrence of life threatening rapid heartbeat in patients with stable ventricular tachycardia (VTACH study)

A randomized controlled trial shows that catheter ablation before ICD implantation reduces VT recurrence at two years, with a 40% lower risk of repeat VT or VF. Prophylactic catheter ablation may be considered for patients with stable VT and reduced left-ventricular function.

Nervous culprit found for Tassie devil facial tumor disease

Researchers have identified the genetic marker for Devil Facial Tumour Disease (DFTD), a transmissible cancer affecting only Tasmanian devils. The discovery reveals that DFTD originates from Schwann cells, which protect peripheral nerve fibres.

To a mosquito, matchmaking means 'singing' in perfect harmony

Researchers have found that male and female mosquitoes harmonize with each other to find a compatible mate. The study reveals that different mosquito forms can travel together despite their genetic diversity, which has significant implications for malaria control.
