An international team of researchers has found a genetic variant that may explain why some people of African ancestry have naturally lower viral loads of HIV, reducing their risk of transmitting the virus and slowing progress of their own illness.
In January 2017, Reddit users read about an alleged case of terrorism in a Spanish supermarket. What they didn’t know was that nearly every detail of the stories, taken from several tabloid publications and amplified by Reddit’s popularity algorithms, was false. Now, Cornell University research has shown that urging individuals to actively participate in the news they consume can reduce the spread of these kinds of falsehoods.
It’s an elegant solution: Remove the habitat of a parasite-carrying aquatic snail and reduce the level of infection in the local community; all while generating more feed and compost for local farmers.
A team of scientists led by the University of Oxford have achieved a significant breakthrough in detecting modifications on protein structures.
Johns Hopkins Applied Physics Laboratory (APL) researchers have developed one of the world’s smallest, most intense and fastest refrigeration devices, the wearable thin-film thermoelectric cooler (TFTEC), and teamed with neuroscientists to help amputees perceive a sense of temperature with their phantom limbs. This advancement, one of the first of its kind, enables a useful new capability for a variety of applications, including improved prostheses, haptics for new modalities in augmented reality (AR) and thermally modulated therapeutics for applications such as pain management.
Ion channels play a crucial role in many cellular processes, including neuronal communication, muscle contraction or cell proliferation. Most multi subunit ion channels exist in two functional states, either closed or open. During gating, one should expect that all subunits undergo conformational changes. The absence of intermediate conduction levels is surprising and asks for an explanation. A team of researchers from the University of Vienna and the Washington University in St. Louis created a smart model system to answer this important question. The study is currently published in Nature Communications.

Opioids remain the most potent and effective pain relievers in medicine, but they’re also among the most addictive drugs that can halt a person’s ability to breathe during an overdose — which can be deadly. Researchers have been racing to develop safer pain reliever drugs that target a specific opioid receptor, called the kappa opioid receptor, that is only found in the central nervous system and not elsewhere in the body, like other opioid receptors.
Chimeric antigen receptor (CAR)-T cells are a powerful, new form of cancer therapy that are being studied to treat blood cancers. Using a new approach, Yale Cancer Center researchers at Yale School of Medicine found a new way to substantially improve the effectiveness of CAR-T cell therapy. The new study was published in Nature Immunology on July 27.

And one of those ways is by allowing residents to have a say in policy making.
Reducing waste is one way to help combat hunger around the world, but stricter control over food loss and waste does not lead to better environmental outcomes, according to researchers at the University of California, Irvine and the University of Colorado Boulder. In a paper published recently in Nature Food, the scientists stress that curbing food spoilage increases the amount of produce in markets, which leads to lower costs.
In the face of existential dilemmas that are shared by all of humanity, including the consequences of inequality or climate change, it is crucial to understand the conditions leading to cooperation. A new game theory model developed at the Institute of Science and Technology Austria (ISTA) based on 192 stochastic games and on some elegant algebra finds that both cases – available information and the lack thereof – can lead to cooperative outcomes.
Water, water, everywhere – not in drops, but as steam. Scientists using NASA’s James Webb Space Telescope have discovered that thirsty planets in the PDS 70 system have access to a reservoir of water. Importantly, the water vapor was found within 100 million miles of the star – the region where terrestrial planets like Earth may be forming. (The Earth orbits 93 million miles from our Sun.)
