Seafarers' scourge provides hope for biofuel future
- ScienceDaily
- 10/3/23 08:21
For centuries, seafarers were plagued by wood-eating gribble that destroyed their ships, and these creatures continue to wreak damage on wooden piers and docks in coastal communities. But new research is uncovering how the tiny marine isopod digests could hold the key to converting wood and straw into liquid...
Chagas disease surveillance focuses on palms, undercover bugs

How dinosaurs rose to prominence
- ScienceDaily
- 10/3/23 08:21
How did dinosaurs become rulers of Earth more than 200 million years ago? Widespread volcanism and a spike in atmospheric carbon dioxide wiped out half of all plant species, and extinguished early crocodile relatives that had competed with the earliest dinosaurs, according to...
New bone-hard biomaterial for surgical screws
- ScienceDaily
- 10/3/23 08:21
Screws used in surgical operations are often made of titanium. They usually have to be removed after a while or replaced by new ones. A new biomaterial makes this unnecessary. It promotes bone growth and is biodegradable.

The sizes of the portions and plates in more than four dozen depictions of the Last Supper -- painted over the past 1,000 years -- have gradually grown bigger and bigger, according to a new study.
How strong is your booze? True strength of alcohol revealed by new portable device
- ScienceDaily
- 10/3/23 08:21
Both legitimate brewers and distillers -- and authorities on the track of illicit alcohol from home stills -- will soon have a helping hand. Measurement experts have unveiled a portable device to determine the strength of alcoholic drinks quickly and easily, almost anywhere. In a new study, the researchers show that their technique is just as accurate, and more sophisticated, than widely used...
Exploring the link between sunlight and multiple sclerosis
- ScienceDaily
- 10/3/23 08:21
For more than 30 years, scientists have known that multiple sclerosis is much more common in higher latitudes than in the tropics. Because sunlight is more abundant near the equator, many researchers have wondered if the high levels of vitamin D engendered by sunlight could explain this unusual pattern of...
Memory may decline rapidly even in stage before Alzheimer's disease
- ScienceDaily
- 10/3/23 08:21
Memory and thinking skills may decline rapidly for people who have mild cognitive impairment, which is the stage before Alzheimer's disease when people have mild memory problems but no dementia symptoms, and even more rapidly when dementia begins, which is when Alzheimer's disease is usually...
Controlling HIV: Highly promising new compound developed
- ScienceDaily
- 10/3/23 08:21
A compound that can inhibit the transfer of HIV from one cell to another has been developed by researchers in France. It acts by saturating a receptor called DC-SIGN, which is used by HIV to ensure its transmission throughout the body.
Cracking the plant-cell membrane code
- ScienceDaily
- 10/3/23 07:00
To engineer better crops and develop new drugs to combat disease, scientists look at how the sensor-laden membranes surrounding cells interact with their environment. But remarkably little is known about how proteins interact with these protective structures. For the first time for any multicellular organism, researchers have analyzed 3.4 million potential protein/membrane interactions and have...
Giant 'microscope' will use neutrons to study glass transition mystery in solid-state research
- ScienceDaily
- 10/3/23 07:00
Scientists are building an electrostatic levitation chamber that will be installed at the Spallation Neutron Source in Oakridge National Laboratory. Using neutrons as a probe, the instrument will allow scientists to watch atoms in a suspended drop of liquid as the drop cools and solidifies. Researchers are particularly eager to see what the new instrument will tell them about the "glass...
Immunology: New Gene Mutation Linked To Antibody Deficiency
- ScienceDaily
- 10/3/23 07:00
Individuals who have abnormally low levels of immune molecules known as antibodies have an increased susceptibility to infection with certain types of bacteria. By analyzing one such person, researchers have identified a new genetic cause of antibody deficiency, mutations in the CD81...
Physical therapy exercise program can reduce risk of postnatal depression in new mothers
- ScienceDaily

A physical therapy exercise and health education program is effective in improving postnatal well-being and reducing the risk for postnatal depression.
Another perk of painkillers? Decreased hormone levels may reduce cancer risk
- ScienceDaily
- 10/3/23 05:00
Postmenopausal women who regularly use aspirin and other analgesics (known as painkillers) have lower estrogen levels, which could contribute to a decreased risk of breast or ovarian cancer.
Binge drinking doesn't affect next-day student test-taking
- ScienceDaily
- 10/3/23 05:00
In a first-of-its kind controlled experiment, researchers have found that surprisingly, binge drinking the night before a test does not impact college students' test performance -- although it can affect their moods, attention and reaction times.
Boosting endangered freshwater mussels population
- ScienceDaily
- 10/3/23 05:00
The endangered freshwater mussel species has been given a welcome boost following a 12 year cultivation project. Over 300 of the mussels, which are threatened in many parts of Europe and North America, have been released back into the wild at a range of secret locations in Northern...
Chemotherapy plus synthetic compound provides potent anti-tumor effect in pancreatic cancers
- ScienceDaily
- 10/3/23 05:00
Human pancreatic cancer cells dramatically regress when treated with chemotherapy in combination with a synthetic compound that mimics the action of a naturally occurring "death-promoting" protein found in cells, researchers have found.

Disease-causing mutation disrupts movement of cell's 'power house'
- ScienceDaily
- 10/3/23 05:00
New research shows how a mutation causes a common inherited neurodegenerative disease. The study shows that the mutation of a specific protein known to cause Charcot-Marie-Tooth disrupts the movement of mitochondria, the energy-supplying machines inside each cell. The regulated movement of mitochondria along nerve cell fibers is vital to normal communication between the brain and...
