Airway muscle-on-a-chip to aid in search for new asthma treatments

Unfortunately for asthma sufferers and those looking to develop new treatments to help them, animal models traditionally used to test potential new drugs don't always mimic human responses. Joining lungs and guts, scientists at Harvard's Wyss Institute have now developed a human airway muscle-on-a-chip that could help in the search for new treatments for asthma. The device accurately mimics the way smooth muscle contracts in the human airway, both under normal circumstances and when exposed to asthma triggers. Read More

Blood test provides first objective diagnosis of depression in adults

Diagnosing depression can be a difficult task, currently relying on patients reporting symptoms – something those suffering depression don't always do – and doctors correctly interpreting them – which isn't easy as the symptoms are non-specific. Now researchers have developed a blood test to diagnose depression in adults, providing the first objective, scientific diagnosis for the condition.Read More

Turret flight tests to pave the way for laser weapons on military aircraft

High energy laser (HEL) systems have been the subject of military research for decades, but it is only in recent years that the technology has advanced to the point where it is feasible for such systems to be mounted on military ground vehicles and sea vessels. Initial flight tests have now been conducted on a new aircraft laser turret that will help pave the way for HEL systems to be integrated into military aircraft.Read More

Newly-discovered waste-eating bacteria could help in nuclear waste disposal

"Extremophile" bacteria have been found thriving in soil samples from a highly alkaline industrial site in Peak District of England. Although the site is not radioactive, the conditions are similar to the alkaline conditions expected to be found in cement-based radioactive waste sites. The researchers say the capability of the bacteria to thrive in such conditions and feed on isosaccharinic acid (ISA) make it a promising candidate for aiding in nuclear waste disposal.Read More

Put your feet up (for three years): TiVo Mega records over 26,000 hours of TV

TiVo obviously believes things have improved since 1992 when Bruce Springsteen sang about 57 Channels (And Nothin' On). The company has announced the TiVo Mega, a digital video recorder (DVR) that packs a whopping 24 TB capacity. This allows the device to store over 26,000 hours of TV, which translates to around three years of non-stop viewing – which would stretch the endurance of the most dedicated TV marathoner.Read More

Xenon could provide protection for the brain after a blow to the head

Injuries from a blow to the head are a two-stage affair, with the primary injury caused by the initial impact being followed by a secondary injury that develops in the subsequent hours and days. We have seen the development of devices like the Jolt Sensor that are designed to detect the severity of the initial impact, but there is currently no drug treatment for the secondary injury, which is largely responsible for a patient sustaining mental and physical disabilities. Now scientists at Imperial College London have found that xenon gas shows promise as such a treatment.Read More

Activating gene in key organ systems slows aging process throughout the body

With a typical lifespan of around six weeks, the common fruit fly is one animal that could benefit from a slowing of the aging process. And that's just what a team of biologists at UCLA have achieved by activating a gene called AMPK. Possibly of more interest to us higher life forms is the researchers' belief that the discovery could help delay aging and age-related diseases in humans.Read More
