Are talented youth nurtured the wrong way? Top performers develop differently than assumed, says study

Traditional research into giftedness and expertise assumes that the key factors to develop outstanding achievements are early performance (e.g., in a school subject, sport, or in concerts) and corresponding abilities (e.g., intelligence, motor skills, musicality) along with many years of intensive training in a discipline. Accordingly, talent programs typically aim to select the top-performing youth and then seek to further accelerate their performance through intensive discipline-specific training.

However, this is apparently not the ideal way to promote young talent, as a team led by Arne Güllich, professor of sports science at RPTU University Kaiserslautern-Landau, has recently discovered.

The work is published in the journal Science.

Alaska’s Arctic Is Burning Like Never Before in 3,000 Years

Wildfires across Alaska’s North Slope have been more frequent over the last century than at any point in the previous 3,000 years, according to new research published in the journal Biogeosciences.

The work was carried out in Arctic Alaska by an international group of scientists representing institutions in Germany, Poland, the United Kingdom, Romania, and the University of Alaska Fairbanks’ Toolik Field Station.

Angelica Feurdean, the study’s lead author and a senior researcher at Goethe University in Germany, explained that the team combined multiple scientific methods to piece together a long-term record of fire activity. The results suggest that the recent surge in wildfires is linked to expanding woody vegetation and increasingly dry soils, both of which are associated with rising temperatures.

New password spraying attacks target Cisco, PAN VPN gateways

An automated campaign is targeting multiple VPN platforms, with credential-based attacks being observed on Palo Alto Networks GlobalProtect and Cisco SSL VPN.

On December 11, threat monitoring platform GreyNoise observed the number of login attempts aimed at GlobalProtect portals peaked at 1.7 million during a period of 16 hours.

Collected data showed that the attacks originated from more than 10,000 unique IP addresses and were aimed at infrastructure located in the United States, Mexico, and Pakistan.

Comparison of Diagnostic Parameters Using Cardiac CT–derived Aortic Valve Area and Aortic Valve Calcium Scores for Low-Gradient Aortic Stenosis

To compare the performance of cardiac CT–derived hybrid aortic valve area (AVA) and planimetry, in combination with aortic valve calcium (AVC) or AVC density (AVCd), for assessing low-gradient aortic stenosis (LGAS).

‘Ouzo effect’ reveals how oil droplets can resist flow and form stable patterns in liquids

Whether it’s Greek ouzo, French pastis or Turkish raki, when these spirits are diluted with water, the mixture becomes cloudy. The reason for this is that the aniseed oils contained in the spirit dissolve well in alcohol but not in water. The clear ouzo from the bottle has a high alcohol content at which the oil is fully soluble.

However, when water is added, the aniseed oils can no longer dissolve completely in the significantly reduced alcohol content. As a result, small droplets disperse finely in the drink, creating a milky appearance. Researchers at TU Darmstadt have now used this so-called ouzo effect to create oil droplets for a laboratory experiment. This led to a new discovery: such a droplet can resist a fluid flow and remain in place or even move upstream.
