The researchers found those who showed positive age beliefs were 30% more likely to recover from cognitive impairment than those who held negative age beliefs, irrespective of the severity of the cognitive decline. The time for recovery was also quicker in people with positive age beliefs.

They also found that the participants who stayed positive about aging were less likely to develop mild cognitive impairment over 12 years.

It is widely believed that memory loss associated with aging is irreversible. However, a new study says people who embrace aging positively may recover from cognitive decline.

Pneumonia is a potentially fatal lung infection that progresses rapidly. Patients with pneumonia symptoms – such as a dry, hacking cough, breathing difficulties and high fever – generally receive a stethoscope examination of the lungs, followed by a chest X-ray to confirm diagnosis. Distinguishing between bacterial and viral pneumonia, however, remains a challenge, as both have similar clinical presentation.

Mathematical modelling and artificial intelligence could help improve the accuracy of disease diagnosis from radiographic images. Deep learning has become increasingly popular for medical image classification, and several studies have explored the use of convolutional neural network (CNN) models to automatically identify pneumonia from chest X-ray images. It’s critical, however, to create efficient models that can analyse large numbers of medical images without false negatives.

Now, K M Abubeker and S Baskar at the Karpagam Academy of Higher Education in India have created a novel machine learning framework for pneumonia classification of chest X-ray images on a graphics processing unit (GPU). They describe their strategy in Machine Learning: Science and Technology.

Misfolded proteins are toxic to cells. They disrupt normal functions and cause some age-related human degenerative diseases, like Alzheimer’s, Parkinson’s, and Huntington’s diseases. Cells work constantly to eliminate misfolded proteins, but these clearance mechanisms are still poorly understood.

In a new study published April 20 in Nature Cell Biology, researchers at Stanford University discovered a previously unknown cellular pathway for clearing misfolded proteins from the nucleus, the compartment where the cell stores, transcribes, and replicates its DNA. Keeping junk away from those processes is critical to normal cellular function. The new pathway could be a target for age-related disease therapies.

To find the new pathway, researchers in the lab of Judith Frydman, the Donald Kennedy Chair in the School of Humanities and Sciences, integrated several genetic, imaging, and biochemical approaches to understand how yeast cells dealt with misfolded proteins. For the experiments, the team restricted misfolded proteins to either the nucleus or the cytoplasm—the area inside the cell but outside the nucleus. The team visually followed the fate of the misfolded proteins through live-cell imaging and super-resolution microscopy.

NASA landed 12 astronauts on the moon during the Apollo program more than half a century ago. So why is the upcoming Artemis 2 mission just doing a lunary fly-around?

Facebook and Instagram owner Meta will release a commercial A.I. product, following moves from Google, Microsoft, and OpenAI, in 2023 confirmed Reality Labs boss Andrew Bosworth.

Rupert Sheldrake, PhD, is a biologist and author best known for his hypothesis of morphic resonance. At Cambridge University he worked in developmental biology as a Fellow of Clare College. He was Principal Plant Physiologist at the International Crops Research Institute for the Semi-Arid Tropics in Hyderabad, India. From 2005 to 2010 he was Director of the Perrott-Warrick project for research on unexplained human and animal abilities, administered by Trinity College, Cambridge. Sheldrake has published a number of books — A New Science of Life (1981), The Presence of the Past (1988), The Rebirth of Nature (1991), Seven Experiments That Could Change the World (1994), Dogs That Know When Their Owners are Coming Home (1999), The Sense of Being Stared At (2003), The Science Delusion (Science Set Free) (2012), Science and Spiritual Practices (2017), Ways of Going Beyond and Why They Work (2019).

Since its launch in November 2022, ChatGPT, an artificial intelligence (AI) chatbot, has been causing quite a stir because of the software’s surprisingly human and accurate responses.

The auto-generative system reached a record-breaking 100 million monthly active users only two months after launching. However, while its popularity continues to grow, the current discussion within the cybersecurity industry is whether this type of technology will aid in making the internet safer or play right into the hands of those trying to cause chaos.

Enterprise-level network equipment on the secondary market hide sensitive data that hackers could use to breach corporate environments or to obtain customer information.

Looking at several used corporate-grade routers, researchers found that most of them had been improperly wiped during the decommissioning process and then sold online.
