For more than a century, neuroscientists believed that the brains of humans and other mammals differed from the brains of other animals, such as birds (and so were presumably better). Researchers have now found that a comparable region in the brains of chickens concerned with analyzing auditory inputs is constructed similarly to that of mammals.

Scientists are reporting an advance toward the next big treatment revolution in dentistry -- the era in which root canal therapy brings diseased teeth back to life, rather than leaving a "non-vital" or dead tooth in the mouth. Researchers now describe a first-of-its-kind, nano-sized dental film that shows early promise for achieving this long-sought goal.

When the connective tissue under a newborn's tongue is too tight, it prevents the baby from being able to breastfeed properly. A simple surgical snip can fix the problem, but many doctors do not perform the procedure.

Even brief exposure to ultrafine pollution particles near a freeway is potent enough to boost the allergic inflammation that exacerbates asthma, according to new research.

Dramatic scenes are played out under Ralf Sommer’s microscope: his research object, the roundworm Pristionchus pacificus bites another worm, tears open a hole in its side and devours the oozing contents. The squirming victim does not stand a chance in this duel: Caenorhabditis elegans may be a close relative of Pristionchus; unfortunately, however, it does not have the same strong "teeth". Pristionchus’ impressive hunting technique though is not the focus of interest for the biologists. Their concern is the development of its mouthparts.

More than two billion people worldwide do not have adequate access to surgical treatment, according to a new study.

Anyone who has had recurring, chronic aches and pains knows how difficult the pain is to live with and also how very difficult it is to get rid of it.  However, a new study has shown that alternative treatments are of immense benefit for back pain.

As many as 60% of those surveyed said that they had tried some or other (in cases more than one type) of alternative treatment for their back pain and that the CAM (complementary and alternative medicine) therapy had offered exceptional relief. The top therapies that were shown to provide the maximum relief for back pain were:

• Chiropractic Treatment
• Massage
• Yoga
• Tai Chi qi Gong
• Acupuncture
• Herbal remedies
• Relaxation techniques

From among these, it was seen that chiropractic care was the most effective and the most preferred option with 74% people using that to resolve their back pain. Massage therapy came in next; however a range of different alternative remedies were used by back pain sufferers ranging from naturopathy to hypnotherapy.

Though the findings of the study are significant and encouraging in that they show that alternative therapies do work for a great many people, it was disheartening to note that 24% of those surveyed had alternative therapy recommended by their regular medical practitioners.

The guy running the snake down our sewer looks matter-of-fact. Our sewage has been backing up. Right next to the pipe connecting our house to the sewer line running down our street stands a 70-year-old willow oak, and I worry the tree's roots have found their way, during the droughty past year, into our line. He shrugs: Maybe it's tree roots, maybe it's a collapsed pipe, maybe it's a yo-yo. The snake went in only a dozen feet or so and found a clog, and now the little claw at the end is spinning. Once he pulls it out we'll know better what's going on. I leave him to his business, though I cast an annoyed glance at the oak. Sewer pipes fit together simply, with a bell joint, and tiny root hairs find their way to the nutrient-rich flow, then grow larger, eventually growing large enough to shatter the vitreous clay pipe that forms so many service lines or dislodge a joint if the pipes are cast iron. Nobody knows what our pipes, 70 years old, are made of, but I fear we're about to find out.

Fifteen minutes later he's winding the snake back up, writing a bill, and exonerating the oak.
