One shot for life: New research brings us closer to universal flu vaccine

Because the flu mutates so frequently, we have to get a new flu shot every year that's designed for that year's strain of flu. But researchers recently discovered an antibody found in an infected patient's blood that prevents the virus from replicating, even across multiple strains. According to researchers, this effect "is just mind-boggling." The antibody works by targeting a very specific part

Simulated sunlight reveals how 98% of plastics at sea go missing each year

Trillions of plastic fragments are afloat at sea, which cause large "garbage patches" to form in rotating ocean currents called subtropical gyres. As a result, impacts on ocean life are increasing and affecting organisms from large mammals to bacteria at the base of the ocean food web. Despite this immense accumulation of plastics at sea, it only accounts for 1 to 2 percent of plastic debris input

Why have so many new diseases developed in the bagged salads sector?

Ready-to-eat salads, also known as fresh-cut or bagged salads, have steadily gained popularity since their introduction in Europe in the early 1980s. This popularity is expected to grow, marking opportunities for the fresh food industry. As this industry grows dynamically, so does the number of new diseases. There are many reasons for this increase according to a new review in Plant Disease.

The importance of Madagascar's lowland rainforest for lemur conservation

Throughout their evolutionary history, animals in regions with limited lowland habitat have evolved to adapt to higher elevations. Although lemurs — among the most endangered mammals on Earth — are flexible and can persist at intermediate and high elevations in the Madagascar's eastern rainforest, a new study shows that the few remaining patches of lowland rainforest host the highest levels of l

Feast or famine: Scientists find key bio 'switch' that helps cells adapt

Scientists have found that a chemical mark on histones – a key protein involved in the function of our DNA – occurs naturally under nutrient-limited conditions as cells change the way they make energy, and serves to repress genes that would otherwise drive cell growth. The chemical mark is called crotonylation, and until now its function has not been well understood.
