The world's most widely used weed killer may also be indirectly killing bees. New research from The University of Texas at Austin shows that honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria.
Update: After a morning of contradictory reports, it now seems that Deputy Attorney General Rod Rosenstein will remain on the job at least until Thursday. The topsy-turvy story—and the still uncertain ultimate outcome—remind of a core lesson of the Trump years: What happens to U.S. institutions is not something only to watch. An energized public can deter the administration's worst instincts—whet
Russia's unlikely alliance with Israel in Syria is in peril. Today, Moscow announced it would supply Syria with a sophisticated S-300 air-defense system over explicit Israeli reservations. The announcement comes one week after Syria shot down a Russian Ilyushin-20 over the Mediterranean, killing 15 Russian military personnel. Syrian defenses had been targeting Israeli fighter jets that had bombed
Results from the Lipid-Rich Plaque (LRP) study demonstrate the correlation between the presence of non-flow-limiting, non-intervened upon, lipid-rich plaques detected by NIRS-IVUS imaging and the development of a major adverse cardiac event (MACE) from a de novo culprit lesion at both the patient level (vulnerable patients) and segment level (vulnerable plaques) within 24 months post intravascular
The first study designed to determine the benefits of intravascular ultrasound (IVUS) guidance over angiography guidance during drug-eluting stent (DES) implantation in all-comer patients found that IVUS improved clinical outcomes by lowering the rate of target vessel failure at one year.
New evidence supports the idea that plants owe their rainbow of fruit colors to the different animals that eat them. Researchers first had to get past the fact that most animals don't see colors quite the way humans do.

New research from an international team led by Oxford University's Department of Zoology and the National-Kapodistrian University of Athens, published today in Proceedings of the National Academy of Sciences (PNAS), shows that an ancient retrovirus — HK2 — is more frequently found in drug addicts and thus is significantly associated with addiction.
A breakthrough has been made in the fight against Alzheimer's disease — researchers have found a new way to target the toxic particles that destroy healthy brain cells. Academics at the University of Cambridge and at Lund University in Sweden have devised the first strategy to 'go after' the cause of the devastating disease, leading to hope that new drugs could be developed to treat dementia.
Researchers at University of Tsukuba showed that mutation of a single amino acid in the SIK3 protein caused mice to exhibit more non-REM sleep and increased 'sleep need,' including when awake, reflected in particular patterns of brainwave activity. The findings could help research on human sleep disorders given the similarity of this protein to that in humans.
Birds' voiceboxes are in their chests instead of their throats like mammals and reptiles. Scientists aren't sure how or why birds evolved these unique voiceboxes, but a new study in PNAS sheds some light on how they came about. Similarities in the windpipes of birds, crocodiles, cats, mice, and salamanders suggest that birds' weird voiceboxes might have arisen from a windpipe reinforcement. From t
Birds tote around two vocal organs inside their bodies, but only one works. New interdisciplinary research suggests that this distinctly avian anatomy arose because birds, somewhere in their evolutionary history, opted for building a brand new vocal organ — the syrinx– instead of modifying an existing one that is present in an array of animals but silent in birds — the larynx.
Honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria. Scientists believe this is evidence that glyphosate might be contributing to the decline of honey bees and native bees around the world.

Long-held assumptions that stepfathers are far more likely to be responsible for child deaths than genetic parents have been challenged by researchers at the University of East Anglia (UEA).Findings suggest that differences in rates of child homicides by stepfathers and genetic fathers are considerably smaller than previous researchers have claimed, and that the relative ages of fathers implicated
Results of a new international survey of more than 2,500 responders from five countries show that women know more about men's health issues than men do, men have poor knowledge of key urological symptoms and don't take early signs of potentially life-threatening urological conditions seriously.The low level of awareness indicated by the survey is of particular concern as urological conditions are
Obstetricians are often reluctant to recommend restricted weight gain for pregnant women due to safety concerns for the baby and lack of time and tools to safely guide women in their weight control efforts. A new Northwestern Medicine study shows with proper nutrition guidance it is safe and feasible to restrict weight gain in obese and overweight pregnant women. Women in the study gained five pou
When mothers use marijuana during the first 12 years of their child's life, their cannabis-using children are more likely to start at an earlier age than children of non-using mothers, according to a new study from the Harvard T.H. Chan School of Public Health. This study is the first to establish a relationship between maternal cannabis use during a child's lifetime and earlier initiation in a na
Children whose mothers use marijuana are more likely to start their own marijuana use an average of two years earlier than children whose mothers don't use the drug, according to a new study from Harvard T.H. Chan School of Public Health.
Black women are more likely to be diagnosed at later stages of breast cancer partly due to barriers to timely screening mammography. port for their health needs.
An intensive, multifaceted online diabetes prevention program is as effective as in-person programs and can make prevention programs more accessible to those at risk for developing diabetes. Weight loss for online participants was at least comparable to what it was for in-person program participants. In addition, the researchers found that the online program had significantly better participation

A species of seed-feeding fly is critically damaging the seed production of multiple orchid species, as revealed by a group of Japanese researchers. If the damage caused by this fly is occurring long-term and across Japan, these already-endangered orchid species could become unable to reproduce using seeds, and their dwindling numbers will take a large hit.
Using a bioinformatics approach, researchers found that CD4+ T cell's binding partner, a molecule called MHC-II, may have even more influence on emerging tumors than MHC-I, the better known partner of CD8+ T cells. The finding may help researchers improve cancer immunotherapies and predict which patients will respond best.
Scientists have identified another way the process that causes oil to form droplets in water may contribute to solid tumors, such as prostate and breast cancer. Researchers found evidence that mutations in the tumor suppressor gene SPOP contribute to cancer by disrupting a process called liquid-liquid phase separation. Liquid-liquid phase separation is seen often in nature and is the reason why oi
SWEEPER is designed to operate in a single stem row cropping system, with non-clustered fruits and little leaf occlusion.

Researchers from Tokyo Metropolitan University have discovered a new way of controlling the drying patterns formed by re-crystallizing salt. They found that the coffee ring effect can be used to pin the edge of drying droplets, creating a range of different geometric patterns. The same principles may be applied to understand and improve the adhesion of printer ink to surfaces and the manufacture o
Scientists have developed a blood test to tell whether you have skipped a night's sleep, bringing us a step closer to developing a test for driver sleepiness. The breakthrough could help police identify suspected drowsy drivers in road traffic accidents, or assist employers in assessing fitness for duty, such as in the aviation sector.
Experts want action to tackle 'huge public health threat' after new projections Obesity is on track to overtake smoking as the single biggest cause of preventable cancer in British women within 25 years, according to a Cancer Research UK report. The charity expects that within 17 years around 23,000 cases of cancers in women (9% of the total) could be caused by excess weight and about 25,000 (10%
Researchers have identified a new genetic syndrome in a 3-year-old girl who, for more than two years, has gone without diagnosis. The discovery is the first to link a particular gene, known as ODC1, or ornithine decarboxylase, to developmental problems in a human, something that up until now, has been only seen in mice. The findings, which appear in the American Journal of Medical Genetics , coul
Time may not be passing at all, says the Block Universe Theory. Time travel may be possible. Your perception of time is likely relative to you and limited. We seem to perceive time as passing in one direction. After all, we can't just just forward to the future or revisit our past if we felt like it. Every minute of every day appears to move us ahead, pulling us through our lives towards an inexo
A vastly expanding gap in age, gender, and diversity is creating an even deeper divide between the Republican and Democratic parties, according to a new paper by an expert on the 26th Amendment. Jenny Diamond Cheng, a lecturer in law at Vanderbilt University, also argues that this chasm between the nation's largest generation—millennials—and baby boomers is exacerbating voter discrimination. "The
Too many people are missing out on the health benefits of golf, says a panel of international experts in a consensus statement, which aims to widen participation in the sport.The evidence suggests it may not only be good for mind and body, but also for a long life, says the statement, published online in the British Journal of Sports Medicine.
Many have tried to contact the Sentinelese, to write about them, or otherwise. But the inhabitants of the 23 square mile island in the Bay of Bengal don't want anything to do with the outside world. Their numbers are unknown, but either 40 or 500 remain. None Between waves of refugees, armed conflicts, and bickering over oil reserves, the world feels like it's become a rather small place. The wor
Athelstan Spilhaus designed an oceanic thermometer to fight the Nazis, and the weather balloon that got mistaken for a UFO in Roswell In 1942, he produced a world map with a unique perspective, presenting the world's oceans as one body of water The Spilhaus Projection could be just what the oceans need to get the attention their problems deserve This is a world map unlike any other. Uniquely, it
