Here we show that after 20 years, cattle presence decreased total soil carbon and nitrogen pools, while the presence of megaherbivores (mainly elephants) increased these pools and even reversed the negative effects of cattle. Our results suggest that a mix of cattle at moderate densities and ...
Improving the energy and environmental performance of the building sector is an increasingly urgent imperative, although, to this point, most efforts have focused primarily on energy use and associated CO2 emissions. Here, we focus on the local thermal environment effects of buildings. The use of ...

Triple negative breast cancer (TNBC) accounts for 15–20% of breast cancer cases in the United States. Systemic neoadjuvant chemotherapy (NACT), with or without immunotherapy, is the current standard of care for patients with early-stage TNBC. However, up to 70% of TNBC patients have significa...

yet willpower is not enough. technology is designed to psychologically stimulate the reward centers of our brain to keep us coming back for more, mimicking the effects of a physical drug addiction. 30 rectifying this will ultimately require that developers and technologists adopt the human-cent...

The effects of carbon types in the NEs on the electrochemical performance of LICs have been extensively investigated [13], [14], [15], [16]. Among its notable features, graphite has a high theoretical capacity of 372 mAh/g and a low initial irreversible capacity of 5–20% [17]. ...
Nevertheless, cytotoxic drugs are usually used, and many of them may also inhibit effector cells while killing cancer cells5. In addition, prescription of immunosuppressive drugs may be necessary to alleviate the side effects. A new strategy that can simultaneously improve cancer cell eradication and...
There are solutions that exist to overcome the negative effects of externalities. These can include those from both the public andprivate sectors. Taxes Taxes are one solution to overcoming externalities. To help reduce the negative effects of certain externalities such as pollution, governments can ...
