Older Adults who play Digital Puzzle Games have the Same Memory Abilities as People in their 20s, a new study has shown.

Age plays a part in the type of digital games that are best to stimulate memory

The study, from the University of York, also found that adults aged 60 and over who play digital puzzle games had a greater ability to ignore irrelevant distractions, but older adults who played strategy games did not show the same improvements in memory or concentration.

It is known that as humans age, their mental abilities tend to decrease, particularly the ability to remember a number of things at a single time — known as working memory. Working memory is thought to peak between the ages of 20 and 30 before slowly declining as a person gets older.

Previous research, however, has shown that the way we hold information in the brain changes as we get older, and so the York team looked at whether the ...

Surprise COVID Discovery Helps Explain How Coronaviruses Jump Species

DNA-tethering and fusion of SARS-CoV-2 pseudoviruses and virus-like particles (VLP). The experiment design is schematized in panel (a), where DNA-functionalized viral particles are added to a microfluidic flow cell and allowed to bind to protein-free liposomes functionalized with complementary DNA. After unbound particles are washed away, fusion is initiated by addition of a soluble protease and monitored via lipid mixing, detected as fluorescence dequenching of Texas Red dye in the VLP or pseudoviral envelope. Representative images of a 10.1 × 9.6 μm sub-micrograph before and after lipid mixing are shown in panel (b) with a fusing particle outlined in magenta. The corresponding fluorescence intensity trace is plotted in panel (c).

Scientists Identify Genes linked to High Production of Key Antibody

A collaboration led by UCLA and the Seattle Children’s Research Institute has yielded new knowledge about the genes responsible for the production and release of immunoglobulin G, the most common type of antibody in the human body.

The finding has the potential to advance manufacturing of antibody-based therapies for diseases such as cancer and arthritis, as well as the development of medical treatments that rely on the production of antibodies.

Common Cold Virus Linked to Potentially Fatal Blood Clotting Disorder

A new observation suggests that a life-threatening blood clotting disorder can be caused by an infection with adenovirus, one of the most common respiratory viruses in pediatric and adult patients.

Platelets, or thrombocytes, are specialized cellular fragments that form blood clots when we get scrapes and traumatic injuries. Viral infections, autoimmune disease, and other conditions can cause platelet levels to drop throughout the body, termed thrombocytopenia.

After a robust clinical and research collaboration, Stephan Moll, MD, and Jacquelyn Baskin-Miller, MD, both in the UN...
