Weismann Barrier
The Weismann barrier has long been regarded as a basic tenet of biology. However, upon close examination of its historical origins and August Weismann's own writings, questions arise as to whether such a status is warranted. As scientific research has advanced, the persistence of the concept of the barrier has left us with the same dichotomies Weismann contended with over 100 years ago: germ or soma, gene or environment, hard or soft inheritance.

Weeds Enhance Pollinator Diversity in Mango
Weeds increase the diversity of pollinating insects on mango flowers, and mangos with weeds growing below produced more fruit than those without weeds. Weeds can provide ground cover and flowers that can support insect pollinators, natural enemies, and increase biodiversity at the field and landscape level.

Weed Management
Weeds can affect food production in agricultural systems, decreasing the product quality and productivity due to the competition for natural resources. On the other hand, weeds can also be considered to be valuable indicators of biodiversity because of their role in providing ecosystem services. In this sense, there is a need to carry out an effective and sustainable weed management process, integrating the various control methods (i.e., cultural, mechanical and chemical) in a harmonious way, without harming the entire agrarian ecosystem. Thus, intensive mechanization and herbicide use should be avoided.

Weed Detection in Wheat Crops
Wheat (Triticum aestivum L.) is a commonly cultivated cereal worldwide that covers about 237 million hectares annually, producing 765 million tons of yield. Weeds cause economic losses in wheat crops that can range from 40 to 50%, and must be controlled throughout the crop’s growing season to achieve an appropriate crop yield. Weeds constitute unwanted plants that fight with crops for nutrients, resources, and sunlight. They can have a number of detrimental effects, including reducing agricultural yields and unmanageable weed populations.

Wearables as Digital Diagnostics
Wearables, which refer to smart consumer devices that record digital health data, are becoming an integral part of our daily lives. This reflects the growing health consciousness among people. Wearable biosensors are low-price, non-invasive, and non-irritating devices that function by continuously measuring a person’s physiological parameters in real time, which can be used for the early as well as in-depth diagnosis of several conditions. Wearable devices contain different types of sensors that collect data on step counts, heart rate, sleep duration, calories burnt, stress, and oxygen levels.

Wearable Optical Sensor
Miniaturization advances have led to several wearable sensors that are now being employed in a variety of biomedical applications. Some of these have been ingrained in people’s daily lives. Smart bands and smartwatches with pulse monitors, pulse oximeters, accelerometers, gyroscopes, and other sensors are one example.
