Everyone has scents that naturally appeal to them, such as vanilla or coffee, and scents that don’t appeal. What makes some smells appealing and others not? Researchers studied the behavior of the locusts and how the neurons in their brains responded to appealing and unappealing odors to learn more about how the brain encodes for preferences and how it learns.
Developed over the past six years by NYU Tandon's Biomedical Engineering Associate Professor Rose Faghih, MINDWATCH is an algorithm that analyzes a person's brain activity from data collected via any wearable device that can monitor electrodermal activity (EDA).

Herpes viruses are treacherous: once you are infected, you can never get rid of the virus. This is because herpes viruses lie dormant in certain host cells in the body for a lifetime.
Arctic sea ice, an important component of the Earth system, is disappearing fast under climate warming. Summer sea ice is anticipated to vanish entirely within this century.

The key to understanding proteins — such as those that govern cancer, COVID-19, and other diseases — is quite simple. Identify their chemical structure and find which other proteins can bind to them. But there’s a catch.
Cornell researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior of the material, rather than at the edges, as scientists had long assumed.
New research published today in Nature has revealed the importance of mineral forms of iron in regulating the cycling of this bio-essential nutrient in the ocean.
In chemical reactions, molecules transform from reactants into reaction products through a critical geometry called a transition state that lasts less than one millionth of one millionth of a second. Scientists recently captured a critical geometry using the ultra-high speed “electron camera” at SLAC. The research will help explain why reactions generate only specific reaction products.

Cancer research centers conducting clinical trials could enroll more patients from underrepresented racial and ethnic groups by placing greater emphasis on relieving investigators of the costs of translating consent documents into languages other than English, according to a UCLA Jonsson Comprehensive Cancer Center study.
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.
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.
