Nanotubes enable travel of Huntington's protein

A toxic protein linked to Huntington's disease can move from neuron to neuron through a nanotube tunnel whose construction is initiated by a protein called Rhes, say scientists at Scripps Research.

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.

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.

Pixel 3a vs. Pixel 3: Great camera for the price makes Google's $399 phone the better buy

Google's launch Tuesday of the $399 Pixel 3a and $479 Pixel 3a XL smartphones only seven months after the release of the pricier Pixel 3 and Pixel 3 XL handsets likely has you asking: "Why would I want to spend at least $400 more for Google's premium flagships, when these latest mid-priced devices offer so many overlapping features?"

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.

Using AI to predict breast cancer and personalize care

Despite major advances in genetics and modern imaging, the diagnosis catches most breast cancer patients by surprise. For some, it comes too late. Later diagnosis means aggressive treatments, uncertain outcomes, and more medical expenses. As a result, identifying patients has been a central pillar of breast cancer research and effective early detection.
