Babies’ Language Learning Starts From The Womb
Artist’s rendering of a human fetus growing inside the womb.
From their very first days, newborns’ cries already bear the mark of the language their parents speak, reveals a new study published online on November 5th in Current Biology, a Cell Press publication. The findings suggest that infants begin picking up elements of what will be [...]
Domestic Horse Genome Sequenced
Twilight, a Thoroughbred horse from Cornell University.
An international team of researchers has decoded the genome of the domestic horse Equus caballus, revealing a genome structure with remarkable similarities to humans and more than one million genetic differences across a variety of horse breeds. In addition to shedding light on a key part of the mammalian [...]
Gene Therapy Technique Slows Brain Disease ALD Featured In Movie ‘Lorenzo’s Oil’
This figure represents four cells, four purified CD34+ (the CD34+ cell population comprises true hematopoetic stem cell) from patient P1.
A strategy that combines gene therapy with blood stem cell therapy may be a useful tool for treating a fatal brain disease, French researchers have found.
Caught In The Act: Butterfly Mate Preference Shows How One Species Can Become Two
Polymorphic mimicry in Heliconius cydno alithea in western Ecuador, where the white form mimics the white species Heliconius sapho and the yellow form mimics the yellow species Heliconius eleuchia.
Breaking up may actually not be hard to do, say scientists who’ve found a population of tropical butterflies that may be on its way to a split [...]
Common Plants Can Eliminate Indoor Air Pollutants
Hemigraphis alternata, or purple waffle plant, one of the highest ratedornamentals for removing indoor air pollutants.
Air quality in homes, offices, and other indoor spaces is becoming a major health concern, particularly in developed countries where people often spend more than 90% of their time indoors. Surprisingly, indoor air has been reported to be as much [...]
Tiny Laser-scanning Microscope Images Brain Cells In Freely Moving Animals
New data from rats with head-mounted microscopes shed light on how we put the world together seamlessly while we move around.
By building a tiny microscope small enough to be carried around on a rats` head, scientists at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany, have found a way to study the complex [...]
‘Spoonful Of Sugar’ Makes The Worms’ Life Span Go Down
C. elegans.
If worms are any indication, all the sugar in your diet could spell much more than obesity and type 2 diabetes. Researchers reporting in the November issue of Cell Metabolism, a Cell Press publication, say it might also be taking years off your life.
Vast Right Arm Conspiracy? Study Suggests Handedness May Affect Body Perception
Body maps in our brain may influence how we perceive our physical bodies — for example, if there is a lot of brain area associated with our right arm, we will view it being as longer compared to our left arm.
There are areas in the brain devoted to our arms, legs, and various parts of [...]
Eating Quickly Is Associated With Overeating, Study Indicates
Eating a meal quickly, as compared to slowly, curtails the release of hormones in the gut that induce feelings of being full, according to new research.
According to a new study accepted for publication in The Endocrine Society’s Journal of Clinical Endocrinology & Metabolism (JCEM), eating a meal quickly, as compared to slowly, curtails the release [...]
Origin Of Cosmic Rays: VERITAS Telescopes Help Solve 100-year-old Mystery
This representative-color figure shows the very-high-energy gamma-ray emission observed by VERITAS coming from the Cigar Galaxy, also known as Messier 82.
Nearly 100 years ago, scientists detected the first signs of cosmic rays — subatomic particles (mostly protons) that zip through space at nearly the speed of light. The most energetic cosmic rays hit with the [...]
African Desert Rift Confirmed As New Ocean In The Making
New research confirms that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea.
In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed [...]
Nasca People Of Ancient Peru: Forest Clearances Sealed Civilization’s Downfall
Nazca Lines in the Peruvian Desert.
An ancient South American civilisation which disappeared around 1,500 years ago helped to cause its own demise by damaging the fragile ecosystem that held it in place, a study has found.
NASA’s Fermi Telescope Detects Gamma Rays From ‘Star Factories’ In Other Galaxies
Fermi’s Large Area Telescope (LAT) shows that an intense star-forming region in the Large Magellanic Cloud named 30 Doradus is also a source of diffuse gamma rays.
Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA’s Fermi Gamma-ray Space Telescope. Two so-called “starburst” galaxies, plus a [...]
Terrible Teens Of T. Rex: Young Tyrannosaurs Did Serious Battle Against Each Other
Young tyrannosaurs did serious battle against each other.
We all know adolescents get testy from time to time. Thank goodness we don’t have young tyrannosaurs running around the neighborhood.
Venomous Shrew And Lizard: Harmless Digestive Enzyme Evolved Twice Into Dangerous Toxin In Two Unrelated Species
A harmless digestive enzyme can be turned into a toxin in two unrelated species — a shrew (pictured) and a lizard — thereby giving each a venomous bite.
Biologists have shown that independent but similar molecular changes turned a harmless digestive enzyme into a toxin in two unrelated species — a shrew and a lizard — [...]
Next-generation Microcapsules Deliver ‘Chemicals On Demand’
A new generation of microcapsules, shown above, promise to deliver “chemicals on demand” for a wide range of uses, including medicine and personal care.
Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen. The new [...]
Angry Faces: Facial Structure Linked To Aggressive Tendencies, Study Suggests
New research finds that a quick glance at someone’s facial structure may be enough for us to predict their tendency towards aggression.
Angry words and gestures are not the only way to get a sense of how temperamental a person is. According to new findings in Psychological Science, a quick glance at someone’s facial structure may [...]
Regeneration Can Be Achieved After Chronic Spinal Cord Injury
Mark Tuszynski, MD, PhD.
Scientists at the University of California, San Diego School of Medicine report that regeneration of central nervous system axons can be achieved in rats even when treatment delayed is more than a year after the original spinal cord injury.
HIV Tamed By Designer ‘Leash’
This thin-section transmission electron micrograph (TEM) depicted the ultrastructural details of a number of human immunodeficiency virus (HIV) virus particles, or virions.
Researchers have shown how an antiviral protein produced by the immune system, dubbed tetherin, tames HIV and other viruses by literally putting them on a leash, to prevent their escape from infected cells. The [...]
The Six Golden Rules of Sexting
Message-sent is often different than message-received
Professing your love (or lust) takes just a few seconds of typing in the age of flirtexting, also famously known as sexting. While ‘XOXO’ stands for hugs and kisses, ‘French’ is the new tongue-incheek for French Kiss and ‘IWSN’ (I want sex now) is the best way to tell your [...]

Secrets In A Seed: Clues Into The Evolution Of The First Flowers
Nymphaea lotus.
Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. In the late 1800s, Darwin referred to their development as an “abominable mystery.” To this day, scientists are still challenged by this “mystery” of how angiosperms originated, rapidly diversified, [...]
