Penn researchers find three distinct immune responses for sicker COVID-19 patients

Researchers from the Penn Institute of Immunology discovered three distinct immune responses to the SARS-CoV2 infection that could help predict the trajectory of disease in severe COVID-19 patients and may ultimately inform how to best treat them. A second study from researchers at Penn uncovered new details about the innate, or initial, response to SARS-CoV2.

Polycatenanes in mesoscale

An international research group led by Chiba University has succeeded in forming self-assembled molecule rings called "polycatenanes" without using additional molecular templates. The research group also succeeded in observing the polycatenanes, the longest structure reaching 500 nm, by using atomic force microscopy. This work, published in the journal Nature, is the first vital step in...

Regular physical activity seems to enhance cognition in children who need it most

Researchers at the Universities of Tsukuba and Kobe re-analyzed data from three experiments that tested whether physical activity interventions lead to improved cognitive skills in children. They found that (1) the benefits of regular exercise on cognition were greater in children who have poor cognitive performance before the intervention and (2) spending time on physical activity did not hinder...

Research raises concerns about firearm access for people with dementia

Today, new research released from faculty at the University of Colorado School of Medicine at the Anschutz Medical Campus looked at how caregivers address the issues of firearm safety when taking care of someone who has Alzheimer's Disease and Related Dementias (ADRD) and has access to a gun. The findings published today in JAMA Network Open.

Researchers outline strategy for testing ketone bodies against COVID-19

Given that many of the risk factors for COVID-19 are age-related, a compelling argument can be made that those infected are suffering from an aging-related disease, no matter how old they are. A review published in Med encourages researchers studying metabolism and immunity to turn their attention to ketone bodies, which are being widely studied for their role in aging, as a possible therapeutic...

Scientists identify new material with potential for brain-like computing

Chinedu E. Ekuma and his colleagues at the Sensor and Electrons Devices Directorate at the U.S. Army Research Laboratory have developed a new complex material design strategy for potential use in neuromorphic computing, using metallocene intercalation in hafnium disulfide (HfS2). The work is the first to demonstrate the effectiveness of a design strategy that functionalizes a 2D material with an...

Setting up an alarm system in the Atlantic Ocean

Climate scientists Laura Jackson and Richard Wood from The Met Office, UK have identified metrics that may give us early warnings of abrupt changes to the European Climate. The work is part of the EU Horizon 2020 TiPES project which is coordinated by the Niels Bohr Institute at the University of Copenhagen, Denmark.

Shaking light with sound

Combining integrated photonics and MEMS technology, scientists from EPFL and Purdue University demonstrate monolithic piezoelectric control of integrated optical frequency combs with bulk acoustic waves. The technology opens up integrated ultrafast acousto-optic modulation for demanding applications.

Slow growth the key to long term cold sensing

In this study which appears in Nature, researchers Yusheng Zhao and Rea Antoniou-Kourounioti in the groups of Professor Dame Caroline Dean and Professor Martin Howard at John Innes Centre show that slow growth is used as a signal to sense long-term changes in temperature.
