As many couples trying to conceive know, much can go wrong during that fateful meeting of sperm and egg. Now scientists have identified a new protein eggs use to draw in sperm, which could one day lead to new fertility treatments and contraceptives.

Melanoma is the deadliest form of skin cancer thanks to its ability to rapidly spread to other organs. Brazilian researchers have now developed a peptide that seems to slow the growth and spread of melanoma, improving the survival rates of test mice.
-
Spinal cord injuries are among the most debilitating. In a new breakthrough study, Northwestern University researchers have developed a gel containing “dancing molecules” that allowed paralyzed mice to walk again four weeks after a single injection.

Antibiotic-resistant bacteria are poised to become a major health threat in the coming decades – but new antibiotics may have been inside us all along. A search algorithm has discovered dozens of potential antimicrobial peptides in the human body.
-
Not only are surgical scars unsightly, but their limited elasticity can also reduce the patient's range of motion. There may be new hope, though, as a recent study has shed light on how a therapeutic peptide could drastically reduce such scarring.
-
It's no secret that the more we use antibiotics, the greater the chances that bacteria will develop a resistance to them. A new antibacterial wound dressing is designed to get around that problem, by using proteins instead of regular antibiotics.
-
While snakebite antivenom is certainly a lifesaver, it's also expensive, time-consuming to produce, and must be administered by trained clinicians. A new low-cost type of antivenom, however, could conceivably be self-applied right away, on the spot.
-
Antibiotic-resistant bacteria are poised to become a huge health problem, and we desperately need new treatments. Now, researchers have engineered new antimicrobial molecules from wasp venom, which have shown promise in tests in mice.
-
Spider venom isn’t normally something you want in your body, but there might be exceptions. Australian researchers have identified two peptides from tarantula venom that show promise in blocking organ pain, working particularly well in mice with IBS.
-
Although it's vitally important to keep wounds free of harmful bacteria, antibacterial ointments have to be regularly reapplied, requiring bandages to be removed. A new wound dressing, however, is claimed to continuously kill bacteria all on its own.
-
Treatments for blood clots in the body naturally come with a risk of excessive bleeding from an injury. But a new synthetic blood thinner bypasses this side effect, fighting thrombosis while still allowing blood to clot normally in a wound.
-
Peptides could be a useful type of drug, but they can’t be taken orally because stomach acids destroy them. Now, researchers have developed a new method of testing and creating therapeutic peptides that can survive this degradation.
