Discovery of How to Limit Asthma Attack Damage could Stop Disease

Scientists at King’s College London have discovered a new cause for asthma that sparks hope for treatment that could prevent the life-threatening disease.

Most current asthma treatments stem from the idea that it is an inflammatory disease. Yet, the life-threatening feature of asthma is the attack or the constriction of airways, making breathing difficult. The new study, published in Science, shows for the first time that many features of an asthma attack—inflammation, mucus secretion, and damage to the airway barrier that prevents infections—result from this mechanical constriction in a mouse model.

The findings suggest that blocking a process that normally causes epithelial cell death could prevent the damage, inflammation, and mucus that result from an asthma attack.

Computer Scientists discover Gap in the Latest Security Mechanisms used by some Chips

Over the past few years, hardware manufacturers have developed technologies that ought to make it possible for companies and governmental organizations to process sensitive data securely using shared cloud computing resources. Known as confidential computing, this approach protects sensitive data while it is being processed by isolating it in an area that is impenetrable to other users and even to the cloud provider. But computer scientists at ETH Zurich have now proven that it is possible for hackers to gain access to these systems and to the data stored in them.

The researchers ran two attack scenarios, both using what’s known as the interrupt mechanism, which temporarily disrupts regular processing—for instance to prioritize a different computing task...

New Research Traces the Fates of Stars Living Near the Milky Way’s Central Black Hole

Despite their ancient ages, some stars orbiting the Milky Way’s central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these stars look young for a much darker reason.

They ate their neighbors.

This is just one of the more peculiar findings from new Northwestern University research. Using a new model, astrophysicists traced the violent journeys of 1,000 simulated stars orbiting our galaxy’s central supermassive black hole, Sagittarius A* (Sgr A*).

So densely packed with stars, the region commonly experiences b...

Did you know that Physical Activity can Protect you from Chronic Pain?

UiT researchers have found that physically active people have a lower risk of experiencing chronic pain several years later. “This suggests that physical activity increases our ability to tolerate pain and may be one of the ways in which activity helps to reduce the risk of developing severe chronic pain,” says doctoral fellow Anders Årnes.FOTO: DAVID JENSEN / UIT

One of the reasons is that it increases your pain tolerance. Researchers found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later...
