A pair of chemicals used by wallflowers and their kin to ward off predators have evolved to complement each other, with one targeting generalist herbivores and the other targeting specialised herbivores that have become resistant to the generalist defence.
Key Takeaways:
Researchers identify critical factors at each of three phases of crowdfunding: "friend funding", "getting crowded", and "races to the goal" and the characteristics of crowdfunders contributing to the successful fund raising.
Based on this understanding, fundraisers can maximize both the likelihood of successful fund raising and the amount of capital raised by optimizing fundraising goals, and crowdfunding platforms can optimize their targeting strategies in promotional campaigns and better predict which projects are likely to be successful.
Scientists from the Berlin Institute of Health (BIH), Charité - Universitätsmedizin Berlin and the Thorax Clinic at Heidelberg University Hospital, whose collaboration is taking place under the auspices of the German Center for Lung Research (DZL), have examined samples from non-virus infected patients to determine which cells of the lungs and bronchi are targets for novel coronavirus (SARS-CoV-2) infection. They discovered that the receptor for this coronavirus is abundantly expressed in certain progenitor cells.
CLEMSON, South Carolina -- A team of Clemson University College of Science researchers, in collaboration with international colleagues, has reported the first definitive detection of a relativistic jet emerging from two colliding galaxies -- in essence, the first photographic proof that merging galaxies can produce jets of charged particles that travel at nearly the speed of light.
The brain is permanently exposed to new impressions. Even when sleeping, it does not rest and processes recent experiences. In very early childhood, it has been thought that sleep primarily promotes semantic memory. This includes general knowledge such as the meaning of words.
New Rochelle, NY, April 6, 2020--A team of researchers in Wuhan, China have developed a multidisciplinary self-managed home quarantine method that was effective in controlling the source of COVID-19 infection and was useful in alleviating the shortage of medical resources.

A new report calls for measures to protect elderly people in long-term care facilities and their caregivers who are particularly vulnerable to the COVID-19 pandemic.
Elderly people in long-term care facilities are at high risk of dying from COVID-19 and the risk of transmission of the virus is also especially high at these residences.
ABERDEEN PROVING GROUND, Md. (April 7, 2020) - Team disagreements might be the key to helping Soldiers identify objects in battle, researchers say.
While studies on combat identification typically focus on how technology can help identify enemy forces, researchers sought to understand how teams work together to identify armored vehicles--using only their training and each other.
WASHINGTON, April 7, 2020 -- Tiny biohybrid robots on the micrometer scale can swim through the body and deliver drugs to tumors or provide other cargo-carrying functions. The natural environmental sensing tendencies of bacteria mean they can navigate toward certain chemicals or be remotely controlled using magnetic or sound signals.
To be successful, these tiny biological robots must consist of materials that can pass clearance through the body's immune response. They also have to be able to swim quickly through viscous environments and penetrate tissue cells to deliver cargo.
Bacterial canker of tomato is a disease that leads to wilt, cankers, and eventually death. The disease was first discovered in Grand Rapids, Michigan, in 1909, but annual outbreaks now affect tomato production areas worldwide. For some farmers, bacterial canker can be devastating and spoil an entire season's planting.
OAK BROOK, Ill. (April 7, 2020) - A multinational consensus statement from the Fleischner Society on the role of chest imaging in the management of patients with COVID-19 was jointly published today in the journals Radiology and Chest.
WASHINGTON, April 7, 2020 -- Infertility is estimated to affect 9% of reproductive-aged couples globally, and many couples consequently turn to assisted reproductive technology (ART). Selecting embryos with maximum development potential plays a pivotal role in obtaining the highest rate of success in ART treatment, which ultimately determines whether a couple gets pregnant.
WOODS HOLE, Mass. - A selective mating experiment by a curious butterfly breeder has led scientists to a deeper understanding of how butterfly wing color is created and evolves. The study, led by scientists at University of California, Berkeley, and the Marine Biological Laboratory, Woods Hole, is published today in eLife.
April 07, 2020-- Researchers have identified the most common clinical characteristics of 109 patients with COVID-19 related pneumonia who died in Wuhan, China in the early stages of the coronavirus pandemic, according to a new study published online in the Annals of the American Thoracic Society.
ITHACA, N.Y. - Researchers from Cornell University have identified a possible target for antiviral treatment for COVID-19.
The researchers initially set out to analyze the structure and characteristics of SARS-CoV (severe acute respiratory syndrome coronavirus) and MERS-CoV (Middle East respiratory syndrome coronavirus), with a focus on the spike protein - specifically the fusion peptide - that allows these viruses to infect cells by transferring their genome.
