Vaccine for African swine fever may save our bacon

Náhled

Wild boar can be immunized against African Swine Fever by a new vaccine delivered to the animals in their food. This is the first report of a promising inoculation against this deadly disease, which is a worldwide threat to the swine industry. The study shows immunity can be passed on via contact, but further studies need to examine how this occurs, the safety of repeated administration and its genetic stability as it is passed on.

New material also reveals new quasiparticles

Náhled

Researchers have investigated a novel crystalline material that exhibits electronic properties that have never been seen before. It is a crystal of aluminum and platinum atoms arranged in a special way. This resulted in novel properties of electronic behavior for the crystal as a whole, including so-called Rarita-Schwinger fermions in its interior. Číst dále >>> Přeložit do en

Stem cells make more 'cargo' packets to carry cellular aging therapies

Náhled

media thumbnail Scientists report that adult cells reprogrammed to become primitive stem cells, called induced pluripotent stem cells (iPSCs), make tiny 'cargo packets' able to deliver potentially restorative or repairing proteins, antibodies or other therapies to aged cells. They say the human iPSCs they studied produced much more of the packets, formally known as extracellular vesicles, than other kinds of adult stem cells commonly used for this purpose in research.

Fat fruit flies: High-sugar diet deadens sweet tooth; promotes overeating, obesity in flies

Náhled

media thumbnail Some research suggests that one reason people with obesity overeat is because they don't enjoy food—especially sweets—as much as lean people. Číst dále >>> Přeložit do en

Lions vs. porcupines—Historical records show what leads lions to hunt porcupines and what happens when they do

Náhled

media thumbnail Not much can mess with a lion. They're four-hundred-pound top predators, bringing down large prey like wildebeests, zebras, and even giraffes. But they're not invincible—a new study delves into the interactions between lions and porcupines, and shows how these spiky, cocker spaniel-sized critters can come out on top.

Science Says: Why biodiversity matters to you

Náhled

media thumbnail You may go your entire life without seeing an endangered species, yet the globe's biodiversity crisis threatens all of humanity in numerous unseen or unrecognized ways, scientists say. Číst dále >>> Přeložit do en

Naplňme sklady cisternami místo vzácných kovů, obcí bez vody přibude, požaduje Babiš

Náhled

Po úterním jednání Národní koalice pro boj se suchem premiér také oznámil, že stát počítá s investicemi ve výši 30 miliard. Číst dále >>>

Close relatives can coexist: two flower species show us how

Náhled

media thumbnail Scientists have discovered how two closely-related species of Asiatic dayflower can coexist in the wild despite their competitive relationship. Through a combination of field surveys and artificial pollination experiments, the new study shows that while reproductive interference exists between the two species, both can counter the negative effects of this interference through self-fertilization.
