When Do Infants Begin To Discriminate Pain From Touch?

in medicine, biology

How early can a human brain differentiate painful stimuli from gentle touches? According to a new study, brain wiring necessary to discriminate between a touch and a painful stimulus is in place from 35-37 weeks of gestation in the human brain.

Pigeons produce "milk" with antioxidants - Genomics of the lactating crop

in biology

Deakin University scientists have revealed some of the secrets behind the pigeon’s rare ability to produce ‘milk’ to feed its young by studying the genes behind pigeon ‘milk’ production. They found that, like mammalian milk, it contains antioxidants and immune-enhancing proteins important for the growth and development of the young.

Researchers show they can reverse stem cell aging process

in medicine, biology

Researchers have shown they can reverse the aging process for human adult stem cells, which are responsible for helping old or damaged tissues regenerate. They turned back the clock on adult stem cells aging by suppressing a certain genetic elements called retrotransposons.

Foldit Gamers Solve Protein Folding Puzzle

in technology, medicine, biology, omics

According to a research report, following the failure to solve the crystal structure of a retroviral enzyme by conventional methods, Foldit game players were challenged to produce accurate models. Online gamers solved the structure of the retrovirus enzyme whose configuration had stymied scientists.

Genes that determine coffee drinking

in medicine, biology, omics

How many cups of coffee do you drink every day? Did you know that coffee consumption is a model for addictive behavior? Researchers say they have identified genes that play a role in influencing how much coffee people drink.

Inorganic Chemical Cells - Creating ‘Life’ Without Carbon Bonds

in technology, biology

Scientists at the University of Glasgow say they have taken their first tentative steps towards creating ‘life’ from inorganic chemicals potentially defining the new area of ‘inorganic biology’.

Data capacity of cell signal is lower than the signal from a dial-up modem

in technology, medicine, biology, omics

This might sound strange or unbelievable, but researchers say that the data capacity of cell signal is lower than the signal from a dial-up modem. 

Promising tinnitus discovery could lead to new ways to stop the ringing in the ears

in environment, medicine, biology

Scientists report new approaches to treat tinnitus, including retraining the brain, and new avenues for developing drugs to suppress the ringing in the ears.  Tinnitus, is the perception of sound, such as ringing, within the human ear in the absence of corresponding external sound.
