Manipulating superconductivity using a 'mechanic' and an 'electrician'

In strongly correlated materials such as cuprate high-temperature superconductors, superconductivity can be controlled either by changing the number of electrons or by changing the kinetic energy, or transfer energy, of electrons in the system. Although a large number of strongly correlated materials have been examined with different parameters to understand the mechanism of superconductivity, the range of parameter control is always limited. A versatile experimental method to achieve simultaneous control of the number and the transfer energy of the electrons has been long desired.

Supply-chain hack attacks are worrying investigators

What do you know about supply-chain attacks? In January, an article in CSO said it's when a weak link in your enterprise security might lie with partners and suppliers. It's when someone infiltrates your system through an outside partner or provider with access to your systems and data.

Limiting oxygen could control symptoms of Friedreich's ataxia

Friedreich's ataxia (FRDA) is a rare, inherited disorder that causes progressive damage to the nervous system. This damage leads to ataxia—problems with movement and coordination—that worsens with time. Other symptoms, such as loss of strength and sensation in the arms and legs, muscle stiffness, and impaired speech, hearing, and vision, can also result. New research in cell models and in mice suggests that limited environmental oxygen, known as hypoxia, might one day help FRDA patients, although the safety of doing so is yet unknown.

NASA Northern quadrant strength in Tropical Cyclone Lili

NASA's Aqua satellite used infrared light to analyze the strength of storms in Tropical Cyclone Lili as it moved through the Southern Indian Ocean. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.

HIV prevention drug can curb the epidemic for high-risk groups in India

Pre-exposure prophylaxis (PrEP), a combination drug used to prevent HIV infection, has already gained significant traction in the U.S. and Europe. The once-a-day pill, when taken consistently, can reduce the risk of HIV acquisition by over 85 percent. A new study published in Clinical Infectious Diseases by an international research team suggests that making PrEP available to men who have sex with men (MSM) and people who inject drugs (PWID) in India may be a cost-effective way of curbing the epidemic there.
