If I asked you to imagine your dream snog, chances are it wouldn't be with a Neanderthal; burly and hirsute as they may be. However, my team's new research suggests that these squat beefcakes might have been right up your ancestors' street.

Memory T cells are a special type of white blood cell that "remember" past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found throughout the body: some circulate in the blood, while others settle down as "residents" in tissues like the lungs, intestines and lymphoid organs (such as the spleen and lymph nodes).

Hydrogenases catalyze the reversible splitting and production of hydrogen gas (H2), using complex catalytic cofactors comprising Earth-abundant nickel and/or iron ions. These enzymes, especially the [NiFe]-hydrogenases (fig. 1), are remarkably efficient, making them inspiring models for clean-energy technologies. Yet despite extensive study by many groups worldwide, key steps in their catalytic cycle have remained difficult to observe.

Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune "attack" cells in the pancreatic lymph nodes that appear earlier in the disease could offer the first real chance to detect—and even stop—T1D, according to new research from the Perelman School of Medicine at the University of Pennsylvania detailed in Science Immunology.

Pancreatic cancer is the deadliest form of cancer worldwide, mainly because the disease is often discovered late. Symptoms associated with these tumors are often non-specific, so patients and doctors do not immediately suspect cancer. Moreover, these tumors are difficult to detect in the early stages on abdominal CT scans. Once the diagnosis is made, curative treatment is usually no longer possible. Only 10% of patients survive beyond five years.

We owe a lot to tissue resident memory T cells (TRM). These specialized immune cells are among the body's first responders to disease.

Reducing the U.K.'s energy demand could help the country reach its net zero target faster and at half the cost compared to relying mainly on supply-side technologies, according to new research by energy experts.

The poplar (Populus alba) has a unique survival strategy: when exposed to hot and dry conditions, it curls its leaves to expose the ventral surface, reflecting sunlight, and at night, the moisture condensed on the leaf surface releases latent heat to prevent frost damage. Plants have evolved such intricate mechanisms in response to dynamic environmental fluctuations in diurnal and seasonal temperature cycles, light intensity, and humidity, but there have been few instances of realizing such a sophisticated thermal management system with artificial materials.

Paper packaging is a sustainable alternative to plastic. However, as it is permeable to air, food packaged in paper loses its flavor over time, and undesirable substances such as solvents can penetrate the packaging. Up to now, extensive tests were necessary for each type of paper to determine to what extent and how quickly this happens.

The National Institute of Standards and Technology (NIST) has published a report identifying strategies for developing a more efficient, sustainable and resilient U.S. metals processing infrastructure, where metals are used and reused more efficiently throughout the economy.
