| What did Megalodon eat? Anything it wanted -- including other predators. Posted: 22 Jun 2022 01:45 PM PDT Megalodon sharks, which went extinct about 3 million years ago, were three times longer than modern great white sharks and were apex predators at highest trophic level ever measured. Researchers used the traces of nitrogen trapped in shark tooth enamel to calculate the trophic levels of the prehistoric predators. |
| Surgeons develop new technique to reduce Adam's apple without neck scar Posted: 22 Jun 2022 01:45 PM PDT Doctors at the UCLA Gender Health Program have developed a technique to reduce an Adam's apple bump without leaving a scar on the patient's neck. |
| Indigenous communities used the Caribbean Sea as an aquatic highway Posted: 22 Jun 2022 01:45 PM PDT Researchers recently turned to pottery to tease apart the navigational history of the Caribbean, analyzing the composition of 96 fired clay fragments across 11 islands. The study was conducted in the Greater Antilles and marks the first time that pottery artifacts from the Lucayan Islands -- The Bahamas plus the Turks and Caicos Islands -- have been analyzed to determine their elemental composition and origin. |
| Where once were black boxes, new LANTERN illuminates Posted: 22 Jun 2022 01:45 PM PDT A new statistical tool for predicting protein function could help with tasks ranging from producing biofuels to improving crops to developing new disease treatments. Not only could it help with the difficult job of altering proteins in practically useful ways, but it also works by methods that are fully interpretable -- an advantage over conventional AI. |
| Blood test developed to predict liver cancer risk Posted: 22 Jun 2022 01:45 PM PDT An estimated one-quarter of adults in the U.S. have nonalcoholic fatty liver disease (NAFLD), an excess of fat in liver cells that can cause chronic inflammation and liver damage, increasing the risk of liver cancer. Now researchers have developed a simple blood test to predict which NAFLD patients are most likely to develop liver cancer. |

| Biomarkers found that could be drug targets against a deadly form of brain cancer Posted: 22 Jun 2022 11:19 AM PDT Biomarkers that could be targets for novel drugs to treat glioblastoma brain tumors have been identified, providing hope for a cancer that is highly lethal. This new finding provides early evidence that there may be a benefit in targeting specific alterations in cancer cells with newer agents once a patient's tumor becomes resistant to temozolomide. |
| Flicker from the dark: Reading between the lines to model our galaxy's central black hole Posted: 22 Jun 2022 11:19 AM PDT Researchers have shown in a single model the full story of how gas travels in the center of the Milky Way -- from being blown off by stars to falling into the black hole. |
| How humans evolved to get along (to extent that we do) Posted: 22 Jun 2022 11:19 AM PDT The research shows that four neighboring groups of bonobos they studied at the Kokolopori Bonobo Reserve in the Democratic Republic of Congo maintained exclusive and stable social and spatial borders between them, showing they are indeed part of distinct social groups that interact regularly and peacefully with each other. |
| Scientists identify sensor underlying mechanical itch Posted: 22 Jun 2022 11:18 AM PDT New finding could lead to better drug treatments for chronic itch conditions, like eczema. |
| Attitudes around older motherhood too often emphasize risk and pregnancy timing Posted: 22 Jun 2022 11:18 AM PDT A political science professor argues that much of the official language around older motherhood is rooted in both ageism and ableism, as well as being out of step with current childbirth trends. The average age of childbirth has been rising steadily since the mid-1960s, and in some countries, more women are giving birth between the ages of 35 to 39 than between 20 and 24. But societal expectations of mothers remain largely unchanged. |
| Fights in pro hockey don't deter greater violence, study finds Posted: 22 Jun 2022 11:18 AM PDT Allowing fights among players in the National Hockey Leagues does not deter greater violence in the modern game, according to a new study. |
| Uncovering links between grit and cognitive function Posted: 22 Jun 2022 11:18 AM PDT Gritty people may be more able to self-regulate and show 'cautious control' -- but don't necessarily have greater cognitive ability, according to a new study. |
| Hormones are linked with sleep apnea, snoring in postmenopausal women Posted: 22 Jun 2022 11:18 AM PDT A new study has found an association between obstructive sleep apnea risk and low estrogen and progesterone levels in women. |
| Organic bipolar transistor developed Posted: 22 Jun 2022 10:08 AM PDT Researchers have developed a highly efficient organic bipolar transistor. The work opens up new perspectives for organic electronics -- both in data processing and transmission, as well as in medical technology applications. |
| Posted: 22 Jun 2022 10:07 AM PDT To identify variations in climate across Maine wild blueberry fields at different times of the day and year, researchers analyzed annual and seasonal data from 1980-2020 for Washington, Hancock, Piscataquis, Waldo, Knox, Lincoln, Kennebec and York counties. They found that location, season and the time of day influence how fast temperatures are rising at wild blueberry fields due to climate change. |
| Pushing T cells down 'memory lane' may improve cancer therapy Posted: 22 Jun 2022 10:07 AM PDT Scientists have identified proteins that help decide T cell fate and used the finding to improve CAR-T cell therapy in a solid tumor model. |
| New understanding of congenital heart disease progression opens door to improved treatment options Posted: 22 Jun 2022 10:07 AM PDT Researchers have uncovered new insights into the mechanisms underlying the progression of congenital heart disease (CHD) -- a spectrum of heart defects that develop before birth and remain the leading cause of childhood death. |
| Women in science receive less credit for their contributions Posted: 22 Jun 2022 08:32 AM PDT Women in science are less likely than their male counterparts to receive authorship credit for the work they do, new research finds. Researchers for the first time used a large set of administrative data from universities that revealed exactly who was involved with and paid on various research projects. |

| Engineers devise a recipe for improving any autonomous robotic system Posted: 22 Jun 2022 07:14 AM PDT Engineers devised a recipe for improving any autonomous robotic system. Their optimization code can automatically identify how and where to tweak a system to improve a robot's performance. |
| Optical microphone sees sound like never before Posted: 22 Jun 2022 07:14 AM PDT A camera system can see sound vibrations with such precision and detail that it can reconstruct the music of a single instrument in a band or orchestra. Even the most high-powered and directed microphones can't eliminate nearby sounds, ambient noise and the effect of acoustics when they capture audio. The novel system uses two cameras and a laser to sense high-speed, low-amplitude surface vibrations. These vibrations can be used to reconstruct sound, capturing isolated audio without inference or a microphone. 'We've invented a new way to see sound,' said Mark Sheinin, a post-doctoral research associate at the Illumination and Imaging Laboratory (ILIM) in the RI. |
| TB treatment during pregnancy is safe for mom and baby, study suggests Posted: 22 Jun 2022 07:13 AM PDT Seven out of 10 pregnant women were cured of their multidrug-resistant tuberculosis and delivered healthy babies after taking a medication that had previously been considered unsafe in pregnancy, a new study has found. |
| Reducing air pollution can support healthy brain development Posted: 22 Jun 2022 07:07 AM PDT A new study finds that having a portable air cleaner in the home can reduce the negative impacts of air pollution on brain development in children.
