Exploring the evolution of social norms with a supercomputer

Posted by in categories: evolution, supercomputing

Researchers from the RIKEN Center for Computational Science (Japan) and the Max Planck Institute for Evolutionary Biology (Germany) have published new findings on how social norms evolve over time. They simulated how norms promote different social behavior, and how the norms themselves come and go. Because of the enormous number of possible norms, these simulations were run on RIKEN’s Fugaku, one of the fastest supercomputers worldwide.

New Malware Hits 300,000 Users with Rogue Chrome and Edge Extensions

Posted by in category: cybercrime/malcode

An ongoing, widespread malware campaign has been observed installing rogue Google Chrome and Microsoft Edge extensions via a trojan distributed via fake websites masquerading as popular software.

“The trojan malware contains different deliverables ranging from simple adware extensions that hijack searches to more sophisticated malicious scripts that deliver local extensions to steal private data and execute various commands,” the ReasonLabs research team said in an analysis.

“This trojan malware, existing since 2021, originates from imitations of download websites with add-ons to online games and videos.”

Sonos Speaker Flaws Could Have Let Remote Hackers Eavesdrop on Users

Posted by in category: cybercrime/malcode

Cybersecurity researchers have uncovered weaknesses in Sonos smart speakers that could be exploited by malicious actors to clandestinely eavesdrop on users.

The vulnerabilities “led to an entire break in the security of Sonos’s secure boot process across a wide range of devices and remotely being able to compromise several devices over the air,” NCC Group security researchers Alex Plaskett and Robert Herrera said.

Successful exploitation of one of these flaws could allow a remote attacker to obtain covert audio capture from Sonos devices by means of an over-the-air attack. They impact all versions prior to Sonos S2 release 15.9 and Sonos S1 release 11.12, which were shipped in October and November 2023.

Fasting-Style Diet Seems to Result in Dynamic Changes to Human Brains

Posted by in categories: biotech/medical, food, neuroscience

Scientists looking to tackle our ongoing obesity crisis have made an important discovery: Intermittent calorie restriction leads to significant changes both in the gut and the brain, which may open up new options for maintaining a healthy weight.

Researchers from China studied 25 volunteers classed as obese over a period of 62 days, during which they took part in an intermittent energy restriction (IER) program – a regime that involves careful control of calorie intake and relative fasting on some days.

Not only did the participants in the study lose weight – 7.6 kilograms (16.8 pounds) or 7.8 percent of their body weight on average – there was also evidence of shifts in the activity of obesity-related regions of the brain, and in the make-up of gut bacteria.

New Biomaterial Could Finally Repair Damaged Cartilage in Injured Joints

Posted by in categories: innovation, materials

The body is pretty good at repairing itself, but some parts of our anatomy struggle to bounce back after an injury.

One such material is cartilage – the spongy yet firm connective tissue that keeps our bones from rubbing and jarring against each other. Over time, the translucent or ‘hyaline’ components of cartilage can become heavily degraded, resulting in painful conditions like osteoarthritis and chondromalacia.

Scientists have been working on a way to regenerate hyaline cartilage for years, and now a team led by Northwestern University in the US has achieved a breakthrough. They have developed a biomaterial that, injected into damaged cartilage in living sheep, acted as a scaffold that promoted cartilage regrowth in active joints.

Scientists discover microwaves are home to swarms of radiation-resistant bacteria

Posted by in category: biological

The kitchen can be a messy place in any home – some more than others, as anyone who’s lived in a student flat can attest to – but it turns out the humble microwave is home to far more microbes than you could possibly imagine.

And, not only that, but the bacteria these devices are hoarding is resistant to radiation and multiplying by the second.

A new study from a team from Darwin Bioprospecting Excellence SL in Paterna, Spain, published in journal Frontiers in Microbiology has found that hardy microbes able to adapt to extreme conditions and thrive in microwaves.

Serotonin changes how people learn and respond to negative information

Posted by in categories: biotech/medical, health

Increasing serotonin can change how people learn from negative information, as well as improving how they respond to it, according to a new study published in the journal Nature Communications.

The study by scientists at the University of Oxford’s Department of Psychiatry and the National Institute of Health and Care Research (NIHR) Oxford Health Biomedical Research Center (OH BRC) found people with increased serotonin levels had reduced sensitivity to punishing outcomes (for example, losing money in a game) without significantly affecting sensitivity to rewarding ones (winning money).

The study involved 26 participants who were given the drug to increase serotonin, with a further 27 in a , who were asked to do a series of tasks measuring learning and behavioral control. State-of-the-art models were then used to understand participant behavior.
