Bitter or sweet? The same taste bud can tell the difference

...iven the current findings, Herness thinks that CCK tells the brain that something bitter is on the tongue, while NPY sends a message that something sweet is being eaten. "We were surprised to see that NPY had the exact opposite action of CCK," he said. "But this would ensure that the brain gets a clear me...

Two designer drugs hit same lung cancer target, but only one is effective

...ly effective in those carrying a mutant EGFR. "It tells us something about the difference in the drugs' ability to cause a regression of the cancer by shutting down the abnormally active growth signal receptor, EGFR," says Janne. "If you want to choose a way of inhibiting the mutant EGFR receptor, you wou...

Monkeys understand numbers across senses

...between two different sensory modalities, and this tells us that language is not necessary to represent number abstractly," she said. "When we humans apply the word 'three' to sounds or visual images, we're using language to link these different sets from different modalities. And the question has been whe...

New discovery blurs distinction between human cells and those of bacteria

...hat struck me is how tightly packed they are. That tells us the shell plays an important role in controlling what comes in and goes out. When we saw how the many hexagons come together, we saw that they filled the space tightly as well." The UCLA biochemists determined the structures from their analysis o...

Field tested: Grasslands won't help buffer climate change as carbon dioxide levels rise

Study provides insight into cellular defenses against genetic mutation

...the first time that the mRNA-binding protein CBP80 tells the NMD system which mRNAs to review for nonsense codons," according to Lynne E. Maquat, Ph.D., professor of Biochemistry and Biophysics at the Medical Center, and senior author of the Nature piece together with post-doctoral associate Nao Hosoda, Ph...

Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see

...inhibited just the cells that excited it, and that tells us there is specificity in these fine-scale circuits." They then went on two show that these neuron pairs with two-way connections belonged to the same fine-scale subnetworks. "This means that inhibitory circuits can also precisely influence the act...

The earliest animals had human-like genes

... of Platynereis genes we have been able to look at tells a very clear story," says researcher Florian Raible, who performed most of the computer analyses. "The worm's genes are very similar to human genes. That's a much different picture than we've seen from the quickly-evolving species that have been stud...

Newly discovered birdlike dinosaur is oldest raptor ever found in South America

..."Buitreraptor is one of those special fossils that tells a bigger story about the Earth's history and the timing of evolutionary events," says Makovicky, lead author of the Nature paper. "It not only provides definitive evidence for a more global distribution and a longer history for dromaeosaurs than was ...

Scientists map one of biology's critical light-sensing structures

...laborating senior authors of the Nature paper. "It tells plants when to germinate. It tells them where to grow to absorb the most light and to avoid competition. It tells them when to flower. ...

How does Mycobacterium tuberculosis infect the lung?

... those with different lung diseases, and what that tells us about the way the infection spreads in the lung. In particular, they looked at the surface of the lung cells, because this is the part directly involved in the first contact with the Mycobacterium. As they report now in the international open-acce...

Molecular research suggest shift needed in how some drugs are created

...s that contain death-domains. "What our structure tells us is that the particular arrangement that was seen in the structure that was solved by the researchers at Dallas Southwestern cannot possibly exist in humans, because of bad steric interactions that preclude the formation of this particular complex,...

Scientists narrow the time limits for the human and chimpanzee split

...oes not pinpoint the precise time of the split, it tells us that proportional differences on branches in family trees should be considered when proposing new times. For example, we now know that a 10-to-12-million-year human-chimp split would infer a divergence of Old World monkeys from our lineage that i...

Scientists develop protein-sequence analysis tool

... property such as charge or polarity. "Experience tells us that such positions are likely to be biologically important for defining the specific functions of the two protein classes," Shanklin said. When the Brookhaven team used the program to scan three test cases, each consisting of two groups of relat...

You will remember this

...o memory but now we have found brain activity that tells how well your memory will work in advance." Two experiments were conducted to tap into long-term memory and arrive at the results. In the first, a symbol was presented on screen a few seconds before each word, telling the subjects what kind of decis...

Embryos tell story of Earth's earliest animals

...r). "This is good news," Raff said. "Embryo size tells us a great deal about the evolution and development of these organisms." The fertilization envelope, a semi-hard membrane that surrounds the urchin envelope, is crucial to the fossilization of the embryo. Without the membrane, or with a broken memb...

Liver cancer linked to cellular repair pathway

...og pathway. During embryonic development, Hedgehog tells cells where and when to grow. In adult tissue, it signals the body to grow new tissue. "If the liver is injured badly, it uses some of the same mechanisms to repair itself as a fetus uses in growing a liver," Diehl said. The Hedgehog pathway is also...

Ultrasounds show mothers' drinking shrinks fetal brain

... Clinical and Experimental Research . "What this tells us is that the earlier you abstain in a pregnancy, the better the outcome," said lead author Nancy Handmaker, a University of New Mexico clinical psychologist with expertise in maternal-fetal health. Alcohol use during pregnancy is a leading preven...

Lactic acid not athlete's poison, but an energy source - if you know how to use it

...t the University of California, Berkeley, however, tells a different story: Lactic acid can be your friend. Coaches and athletes don't realize it, says exercise physiologist George Brooks, UC Berkeley professor of integrative biology, but endurance training teaches the body to efficiently use lactic acid ...
