A new system devises hardware architectures to hasten robots’ response time — ScienceDaily

Contemporary robots can move quickly. “The motors are fast, and they’re powerful,” says Sabrina Neuman. Yet in complex situations, like interactions with people, robots often don’t move quickly. “The hang up is what’s going on in the robot’s head,” she adds. Perceiving stimuli and calculating a response takes a “boatload of computation,” which limits reaction […]

Rhesus macaques develop promising immune response to SARS-CoV-2

In a promising result for the success of vaccines against COVID-19, rhesus macaque monkeys infected with the human coronavirus SARS-CoV-2 developed protective immune responses that might be reproduced with a vaccine. The work was carried out at the California National Primate Research Center at the University of California, Davis and is published Jan. 22 in […]

Hurricanes Wakes Show Asymmetrical Response in Ocean Salinity

Hurricanes (known as tropical cyclones in the Pacific) often form in response to above average ocean surface temperatures. But they are also well known to leave a cold wake after their passage mainly because the strong winds stir and upwell the colder water that lies below the surface layer. While one might expect […]

An augmented immune response explains the adverse course of COVID-19 in patients with hypertension

This most likely explains the augmented response of the immune system and the more severe disease progression. However, certain hypertension-reducing drugs known as ACE inhibitors can have a beneficial effect. They not only lower blood pressure, but also counteract immune hyperactivation. The scientists have now published their findings in the journal Nature Biotechnology. More than […]

Single-dose COVID-19 vaccine triggers antibody response in mice — ScienceDaily

Across the world, health care workers and high-risk groups are beginning to receive COVID-19 vaccines, offering hope for a return to normalcy amidst the pandemic. However, the vaccines authorized for emergency use in the U.S. require two doses to be effective, which can create problems with logistics and compliance. Now, researchers reporting in ACS Central […]

Response to infection therapy better understood thanks to a new technique

Infectious diseases are caused by pathogenic viruses, bacteria, fungi or parasites. The treatment of bacterial and fungal infections relies particularly on antimicrobial drugs, while the focus in treating viral infections is the alleviation of symptoms. Initial therapy for infection is often empiric and guided by clinical presentation. Its efficacy on the pathogen is, however, only […]

Dual-acting immuno-antibiotics block an essential pathway in bacteria and activate the adaptive immune response — ScienceDaily

Wistar Institute scientists have discovered a new class of compounds that uniquely combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance (AMR). These finding were published today in Nature. The World Health Organization (WHO) has declared AMR as one of the top 10 global public […]

Diseased cell fragments burst from pockets in immune cells to activate response

Researchers at the Francis Crick Institute have uncovered an important process in how our immune system detects signs of disease and activates a protective response. This understanding could improve efforts to find new and effective immunotherapy treatments for diseases like cancer. In their study, published in Nature Immunology, the scientists found a mechanism by which […]

Modification of the oxytocin gene is correlated with personal distress, an emotional response related to empathy, scientists show — ScienceDaily

Our ability to feel and understand the emotions of others, or “empathy,” is at the core of our prosocial behaviors such as cooperation and caregiving. Scientists have recognized two types of empathy: cognitive and affective. Cognitive empathy involves understanding another person’s emotions on an intellectual level, taking into consideration someone’s situation and how they would […]
