Coffee - stroke protection

10.10.2010

According to a study conducted at the University of Cambridge (England) involving more than 20 Caucasian men and women aged 39 to 79, coffee may protect against strokes. Over 12 years, 855 cases of stroke were noted in this large sample.

Among coffee drinkers there were 29% fewer of them than among those who prefer other drinks. And it doesn’t matter what method the espresso coffee was prepared with, simple boiling, drip coffee maker or another method. So does decaffeinated coffee, and even instant coffee.

The protective effect applies to those who drink four cups a day, and those who need one. The reasons for the phenomenon remain unclear, but it is suggested that it may be due to the expansion of brain vessels under the influence of coffee.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Samsung has released a mobile phone with a hard drive 23.12.2005

Samsung Electronics is launching its new SPH-V7900 mobile phone, which is notable for having a hard drive inside.

Moreover, this is the second model of a mobile phone from Samsung equipped with a hard drive. The previous phone of this type - SPH-V5400 - was released in December 2004. Its hard drive capacity was 1,5 GB, and the new SPH-V7900 has a 3 GB hard drive (for comparison, most modern cell phones have 100 MB internal memory ).

Of course, any data can be written to 3 GB, but if these are audio, photo or video files, then they can be played directly on the SPH-V7900 phone (MPEG-4 / H.264 video files and MPEG-4 audio files are supported AAC, AAC+ and MP3). The available 2 GB is enough for 3-700 hours of video or XNUMX songs.

The phone also has a function of converting music into visual images. The main TFT LCD screen of the phone has a resolution of QVGA (240x320 pixels) and support for 262K colors, the second small screen on the outer cover has a resolution of 96x96 pixels and support for 65K colors.

In addition, the phone has a built-in 2-megapixel camera with 2x optical zoom and a connector for displaying recorded images on a TV. The dimensions of the mobile phone case are 103x52x27,6 mm, weight - 165 g. The SPH-V7900 phone, like its predecessor SPH-V5400, will work in CDMA networks, so for now it will be sold only in South Korea, where its price will be about 700 dollars.

True, Samsung is preparing a version of this phone for GSM networks. This model is called SGH-I300, it is also equipped with a 3 GB hard drive and runs on Windows Mobile.
