A SpaceX Falcon 9 rocket thundered into space and delivered a Dragon cargo capsule into orbit on May 22, 2012. The launch began an ambitious mission to show that the company is ready to deliver cargo to the International Space Station.
Heart rules the head when we make financial decisions
- ScienceDaily
- 12/5/22 03:36
Our 'gut feelings' influence our decisions, overriding 'rational' thought, when we are faced with financial offers that we deem to be unfair, according to a new study. Even when we are set to benefit, our physical response can make us more likely to reject a financial proposition we consider to be...

Pancreatic cancer may be detected with simple intestinal probe
- ScienceDaily
- 12/5/22 03:35
By simply shining a tiny light within the small intestine, close to that organ’s junction with the pancreas, physicians have been able to detect pancreatic cancer 100 percent of the time in a small study. The light, attached to a probe, measures changes in cells and blood vessels in the small intestine produced by a growing cancer in the adjoining...

Activating genes that suppress tumors and inhibit cancer
- ScienceDaily
- 12/5/21 22:41
A promising new strategy for "reactivating" genes that cause cancer tumors to shrink and die has now been developed. The discovery may aid the development of an innovative anti-cancer drug that effectively targets unhealthy, cancerous tissue without damaging healthy, non-cancerous tissue and vital...
Method to strengthen proteins with polymers
- ScienceDaily
- 12/5/21 22:41
Scientists have synthesized polymers to attach to proteins in order to stabilize them during shipping, storage and other activities. The study findings suggest that these polymers could be useful in stabilizing protein formulations.
Morphing robots and shape-shifting sculptures: Origami-inspired design merges engineering, art
- ScienceDaily
- 12/5/21 22:41
Researchers have shown how to create morphing robotic mechanisms and shape-shifting sculptures from a single sheet of paper in a method reminiscent of origami, the Japanese art of paper folding.
New discoveries about severe malaria
- ScienceDaily
- 12/5/21 22:40
Researchers have uncovered new knowledge related to host-parasite interaction in severe malaria, concerning how malaria parasites are able to bind to cells in the brain and cause cerebral malaria -- the most lethal form of the disease.
Surgical removal of abdominal fat reduces skin cancer in mice
- ScienceDaily
- 12/5/21 22:40
In animal studies, Rutgers scientists have found that surgical removal of abdominal fat from mice fed a high-fat diet reduces the risk of ultraviolet-light induced skin cancer – the most prevalent cancer in the United States with more than two million new cases each year – by up to 80...
Diabetes drug target identified

New research points to the naturally produced protein apolipoprotein A-IV as a potential target for a new diabetes therapeutic.
Modern dog breeds genetically disconnected from ancient ancestors
- ScienceDaily
- 12/5/21 22:38
Cross-breeding of dogs over thousands of years has made it extremely difficult to trace the ancient genetic roots of today's pets, according to a new study.
Richer parasite diversity helps protect frogs from viruses that cause malformed limbs
- ScienceDaily
- 12/5/21 22:38
Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new study.
Today's environment influences behavior generations later: Chemical exposure raises descendants' sensitivity to stress
- ScienceDaily
- 12/5/21 22:38
Researchers have seen an increased reaction to stress in animals whose ancestors were exposed to an environmental compound generations earlier. The findings put a new twist on the notions of nature and nurture, with broad implications for how certain behavioral tendencies might be...
What baboons can teach us about social status
- ScienceDaily
- 12/5/21 22:38
High-ranking male baboons recover more quickly from injuries and are less likely to become ill than other males, biologists have found.
Physical properties predict stem cell outcome
- ScienceDaily
- 12/5/21 22:37
Tissue engineers can use mesenchymal stem cells derived from fat to make cartilage, bone, or more fat. The best cells to use are ones that are already likely to become the desired tissue. Researchers have discovered that the mechanical properties of the stem cells can foretell what they will become, leading to a potential method of concentrating them for use in...
Squid ink from Jurassic period identical to modern cuttlefish ink
- ScienceDaily
- 12/5/21 22:37
Scientists have found that two ink sacs from 160-million-year-old giant squid fossils discovered 2 years ago in England contain the pigment melanin, and that it is essentially identical to the melanin found in the ink sacs of modern-day squid.
Totally RAD: Bioengineers create rewritable digital data storage in DNA
- ScienceDaily
- 12/5/21 22:37
Scientists have devised a method for repeatedly encoding, storing and erasing digital data within the DNA of living cells. In practical terms, they have devised the genetic equivalent of a binary digit -- a "bit" in data parlance.
Hunter-gatherers and horticulturalist lifestyle linked to lower blood pressure increases, atherosclerosis risks
- ScienceDaily
- 12/5/21 22:36
Traditional "hunter-gatherer" and "horticulturalist" populations have significantly lower age-related increases in blood pressure and less risks of atherosclerosis than "modernized" populations. Lifestyle factors of these traditional populations -- high physical activity and high fruit and vegetable diets -- may protect against normal aging phenomena, high blood pressure and hardening of the...
Proven friction stir welding technology brings together reliability and affordability for NASA's space launch system
- ScienceDaily
- 12/5/21 21:35
NASA's next heavy-lift launch vehicle, the Space Launch System, is moving further in development faster thanks to proven advanced technologies like friction stir welding. Friction stir welding uses frictional heating combined with forging pressure to produce high-strength bonds virtually free of defects. The welding process transforms metals from a solid state into a "plastic-like" state, and uses...
Stunning view of Lyrids and Earth at night

- 12/5/21 21:26
NASA's Cassini spacecraft made its closest approach to Saturn's tiny moon Methone as part of a trajectory that will take it on a close flyby of another of Saturn's moons, Titan. The Titan flyby will put the spacecraft in an orbit around Saturn that is inclined, or tilted, relative to the plane of the planet's equator. The flyby of Methone took place on May 20 at a distance of about 1,200 miles...
